From 7244465aec2c3fb53ec30c8b3b089f81ce0be8ee Mon Sep 17 00:00:00 2001 From: TaprootFreak <142087526+TaprootFreak@users.noreply.github.com> Date: Wed, 10 Jun 2026 10:14:14 +0200 Subject: [PATCH 1/7] docs: README project overview + repo map (#221) Restructure the README into a zkCoins project overview, a system-wide repo map (app/sdk/api/node/upstream), and a node-specific guide (trust model, stack, build/run/test, env config, layout, branch flow).

Bitcoin stores only opaque markers that a spend happened — not the coin's contents, which travel privately between sender and receiver as a small encrypted bundle. Double-spend protection is the chain's job; your seed derives every key, your wallet is the only thing that can spend, any node can serve you, and you verify everything against Bitcoin yourself.

ZK proving requires the full private witness, so the node sees, in cleartext: +The node is the **Rust/Axum backend** behind [zkcoins.app](https://zkcoins.app): it scans Bitcoin for Taproot-inscription commitments, maintains the nullifier accumulator and account state, generates and verifies the recursive ZK proofs for every mint/send/receive, persists state to Postgres, and broadcasts the commit/reveal inscription pair back to the chain. It is a single self-hostable container — running your own node is the trustless, private path the whole system is designed around. -- Sender, recipient, and amount of every coin movement -- The complete in-coin / out-coin / source-aggregator slot layout per account -- Account history roots, Merkle proofs, and inclusion-proof witnesses -- Usernames and their bound coin sets (`UsernameStore`) -- Postgres rows persisting all of the above (`node/migrations/000{1,2}_*.sql`) +### Trust model — run your own node -The **on-chain footprint stays private** — Plonky2 ensures that the public outputs (nullifiers, history roots, Taproot inscriptions) carry no readable transaction data. Block explorers and chain analytics see only opaque 64-byte commitments. The trust boundary is therefore the **node operator**, not the chain. +zkCoins follows the **Bitcoin full-node model: your wallet trusts _your_ node, exactly as a Bitcoin wallet trusts your own `bitcoind`.** Proof generation runs inside this process, so the node sees, in cleartext, the sender, recipient, and amount of every movement plus the full witness — the trust boundary is the **node operator, not the chain**. The on-chain footprint stays private: block explorers see only opaque 64-byte commitments. A foreign operator can never steal, forge, or double-spend your coins (that is enforced cryptographically), but it can see your privacy and affect liveness — the same trade-off as using someone else's Electrum/SPV server instead of your own. **If you need full transaction privacy, run your own node.** Full rationale: [`CONTRIBUTING.md` § Trust model](./CONTRIBUTING.md#trust-model--run-your-own-node). -| | Hosted (`api.zkcoins.app`) | Self-hosted | +| | Hosted (`api.zkcoins.app`) | Self-hosted | | --- | --- | --- | | On-chain privacy (vs. block explorers) | ✅ | ✅ | -| Operator sees plaintext transaction data | ❌ Yes — `api.zkcoins.app` is operated by [zkcoins.app](https://zkcoins.app) | ✅ No | +| Operator sees plaintext transaction data | ❌ Yes — operated by [zkcoins.app](https://zkcoins.app) | ✅ No | | Setup effort | ✅ None | ⚠️ Postgres + electrs + Bitcoin node | -**If you need full transaction privacy, run your own node.** Every release is shipped as `zkcoins/node:latest` (see [Live](#live)), the build recipe is [`Dockerfile`](./Dockerfile), and runtime knobs are documented in [Configuration](#configuration).

(Mint and usernames are part of the MVP and are permanently compiled in — no Cargo feature gate.) Concretely: - -- `cargo llvm-cov -p node` (no `--all-features`) must report 100% lines + 100% functions on the activated MVP surface. CI enforces this with `--fail-under-lines 100 --fail-under-functions 100` in the `Coverage Gate (100% lines + functions)` job. The current `develop` baseline is at the gate. -- Defensive code that genuinely cannot be reached in unit tests (e.g. the publisher's Bitcoin-broadcast path that requires a signet/regtest node, the `main.rs` runtime bootstrap) is excluded from the measured scope at the file level rather than tested. -- The branch is protected on GitHub: a PR cannot be merged while CI is red. - -The same rule applies to `zk-coins/app` (gated `NEXT_PUBLIC_ENABLE_*` flags are excluded from the measured scope). - -## Features - -API endpoints, background services, their activation status, and the tests that cover them. - -**Status legend** (current behaviour): `always` = endpoint/service always compiled in · `env` = behavior controlled by a runtime env var · `feature` = compiled in only when the named Cargo feature is enabled at build time, otherwise excluded from the binary · `planned` = listed in Open Tasks, not yet implemented. - -**Triage legend** (MVP testing decision): `mvp` = in MVP scope, must reach full test coverage before launch · `gate` = not in MVP scope; hidden behind a Cargo feature, default off, no test coverage required · `planned` = not in scope for MVP. - -**Coverage legend:** unit % refers to `cargo-llvm-cov` line coverage of the module that implements the function. The MVP-scope per-module summary is in § "Test stack" below; the authoritative live numbers are in the `Coverage Gate` CI job. `—` means no test exists. - -| Function | Trigger | Status | Triage | Tests | -| ------------------------------------ | ------------------------------------- | ------------------------ | ------- | ----------------------------- | -| Health check | `GET /health` | always | mvp | 100% (router) | -| Network info | `GET /api/info` | env¹ | mvp | 100% (router) | -| Get balance | `GET /api/balance?address=` | always | mvp | 100% (router) | -| List per-address history | `GET /api/history?address=&limit=&offset=` | always | mvp | 100% (router) | -| List all addresses | `GET /api/address` | feature (`address-list`) | gate | 100% (router) | -| Admit mint job | `POST /api/jobs/mint` | always² | mvp | 100% (router) | -| Admit send job (phase 1) | `POST /api/jobs/send` | env² | mvp | 100% (router) | -| Attach signed commit (phase 2) | `POST /api/jobs/:id/commit` | env³ | mvp | 100% (router) · 0% (flow) | -| Poll job status | `GET /api/jobs/:id` | always | mvp | 100% (router) | -| Stream job phase events (SSE) | `GET /api/jobs/:id/stream` | always | mvp | 100% (router) | -| Cancel queued job | `POST /api/jobs/:id/cancel` | always | mvp | 100% (router) | -| Receive coin | `POST /api/receive` | always | mvp | 100% (account_node) | -| Download coin proof | `GET /api/proof/:id` | always | mvp | 100% (router) | -| Claim username | `POST /api/username/claim` | always | mvp | 100% (username) | -| Resolve username | `GET /api/username/resolve/:username` | always | mvp | 100% (username) | -| LNURL-Pay metadata | `GET /.well-known/lnurlp/:username` | feature (`lnurl`) | gate | 100% (router) | -| LNURL-Pay callback | `GET /lnurl/pay/:username` | feature (`lnurl`) | gate | 100% (router) | -| Bitcoin block scanner (background) | WS subscription in `scanner_ws.rs` | env⁴ | mvp | 100% (scanner) · — (main, excluded) | -| State persistence (SMT/MMR write) | Scanner callback on commitment match | always | mvp | 100% (state) | -| Taproot inscription broadcast | Called by dispatcher (`flow.rs`) | env³ | mvp | 0% (publisher) | -| Publisher UTXO lookup | Internal, before broadcast | env³ | mvp | 0% (publisher) | -| OpenAPI 3.x spec | `GET /openapi.json` | always | mvp | 100% (openapi_smoke) | -| Swagger UI | `GET /docs` | always | mvp | 100% (openapi_smoke) | -| Explorer endpoints (`/api/stats`, …) | n/a | planned | planned | — | -| Light client support | n/a | planned | planned | — | - -¹ `NETWORK_NAME` env var controls the string returned. `IS_MAINNET=true` flips the default to `"Mainnet"`. -² Proof generation routes through the Plonky2 cyclic-recursion circuit. Single host, single Rust process — no zkVM, no external prover service. Mac Studio M3 Ultra is the production hardware target (96 GB unified memory, no external GPU). See [Proving Strategy](#proving-strategy). -³ Requires `PUBLISHER_KEY` set to a real funded key and `ESPLORA_URL` reachable. With the default test key the node panics on `IS_MAINNET=true` startup; on testnet it accepts the call but broadcast will fail without funded UTXOs — DEV and PRD both return `503 SERVICE_UNAVAILABLE` to the client on broadcast failure (the historic `DEV_SKIP_BROADCAST_FAILURE` env-gate that silently swallowed these failures was removed once DEV and PRD were unified on the MVP-only binary; the DEV publisher wallet therefore has to be funded for E2E paths). -⁴ Scanner depends on `ESPLORA_URL` (REST, used for the per-block `get_block_txids` / `get_tx` lookups and for the post-reconnect tip anchor) AND `ESPLORA_WS_URL` (WebSocket, used by `scanner_ws` to receive new-tip events — issue #84). Both are required env vars with no default; see [Configuration](#configuration) for per-stage values. On connection failure the WS subscriber reconnects with exponential backoff capped at 30 s. - -### Cargo features - -All non-MVP routes are gated by Cargo features so the disabled handler functions, helper structs, and `AppState` fields are excluded from the binary at compile time. With a feature off, the route is never registered and the fallback responds with `404`. There is no runtime path that can reach a disabled handler. Defaults are empty (fail-closed): **both the DEV and the PRD image builds pass no features**, so the two environments run the identical MVP-only binary. The Cargo flags exist for self-hosters who want to compile a binary with a specific non-MVP subset enabled, and for future per-feature rollouts when an individual feature is deemed ready for production. - -| Feature | Gates | -| -------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------- | -| `address-list` | `GET /api/address` | -| `lnurl` | `GET /.well-known/lnurlp/:u`, `GET /lnurl/pay/:u` | - -Build the MVP-only binary (DEV + PRD ship this): `cargo build --release -p node`. Build with every feature enabled (CI clippy + tests + self-host opt-in): `cargo build --release -p node --all-features`. The Docker `FEATURES` build arg accepts a comma-separated list and is forwarded to `cargo build --features`; both `deploy-dev.yaml` and `deploy-prd.yaml` leave it empty. - -### Triage gaps - -Features tagged `mvp` whose current test coverage is insufficient — these block "100% on activated features": - -- **Send — phase 2 (commit + broadcast)** — only error-path tests (`commit_missing_body`, `commit_nonexistent_proof_id`); no happy-path test that exercises the publisher -- **Download coin proof** — only 404 path tested; no test for the happy-path binary stream -- **Bitcoin block scanner** — parsing helpers covered (`scanner.rs` 51%); no integration test against a real Bitcoin block -- **Taproot inscription broadcast** — `publisher.rs` 0%, no tests at all (would need signet/regtest + funded publisher key) -- **Publisher UTXO lookup** — `publisher.rs` 0%, no tests - -### Details - -#### Health check - -- **Module:** `router.rs::main_app` route handler -- **Behaviour:** returns the literal string `"ok"` with HTTP 200 -- **Tests:** `router.rs::tests::health_returns_ok` - -#### Network info - -- **Module:** `router.rs::info_handler` -- **Behaviour:** returns `{ network, capabilities: { address_list, faucet, usernames, lnurl }, username_domain }`. `network` defaults to `Mutinynet` when `IS_MAINNET=false`, `Mainnet` when `true`. `capabilities.{address_list,lnurl}` each reflect whether the corresponding Cargo feature was compiled into this binary, letting clients gate UI on a single node-side source of truth instead of parallel build-time env flags. `capabilities.{faucet,usernames}` are hardcoded `true` — mint and usernames are permanent MVP — and are retained only for back-compat with wallet clients that deserialise the shape. `username_domain` is the external hostname this node serves; **required env var** (node panics on startup if unset). PRD sets `USERNAME_DOMAIN=zkcoins.app`, DEV sets `USERNAME_DOMAIN=dev.zkcoins.app` — distinct from `network` because the same chain can be served from two isolated external hostnames, and the client renders `@` from this field -- **Tests:** `router.rs::tests::info_returns_network_name_capabilities_and_username_domain`, `router.rs::tests::info_serialization_format_is_stable` - -#### Get balance - -- **Module:** `router.rs::get_balance_handler` → `account_node.rs::AccountNode::get_account_balance` -- **Behaviour:** address parsed as hex pubkey, looks up the account. Returns `{ balance, username? }`. A well-formed address with no on-chain activity yields `200 OK` with `balance: 0` (canonical zero state, not 404). The minting address returns `u64::MAX`. Malformed input — invalid hex, wrong length, or a missing `address` query parameter — returns `422` -- **Tests:** `router.rs::tests::balance_*` (6 tests covering happy path, unknown address with and without a claimed username, invalid hex, missing param, wrong length) - -#### List all addresses - -- **Module:** `router.rs::get_address_handler` → `account_node.rs::AccountNode::get_addresses` -- **Behaviour:** returns all known addresses as hex strings. Intended for explorer/debug use, not user-facing -- **Tests:** `router.rs::tests::address_returns_list` - -#### Mint coins (single-phase) - -- **Module:** `router.rs::mint_handler` → `account_node.rs::send_coins` with the node-held minting account -- **Behaviour:** node signs commitment itself (no client roundtrip) using the minting key -- **Proof generation:** `zkcoins_prover::Prover` (the Plonky2 wrapper in [`script-plonky2/`](./script-plonky2/)) — `prove_initial` for new accounts, `prove_account_update` for receivers -- **Tests:** `account_node.rs::tests::test_create_minting_account`, `test_mint_single_invoice`, `test_mint_repro_live_setup` - -#### Send — phase 1 (generate proof) - -- **Module:** `router.rs::send_coin_handler` → `verify_send_signature` (Schnorr over `SHA256(account_address || recipient || amount || timestamp)`, ±5 min skew) → `account_node.rs::send_coins` -- **Behaviour:** returns `{ proof_id, account_state_hash, output_coins_root }`. Proof is persisted under `data/proofs/.bin` for later commit -- **Tests:** request-layer tests in `router.rs::tests::send_*` and `send_signature_*` (12 tests covering parser, signature verification, replay). Proof generation itself is not exercised — the Plonky2 cyclic-recursion build is too slow for unit tests (~3–15 min per prove at production parameters); positive proofs are exercised in `program-plonky2/` directly - -#### Send — phase 2 (commit + broadcast) - -- **Module:** `router.rs::commit_handler` → `publisher.rs::create_and_broadcast_inscription` -- **Behaviour:** verifies the client's Schnorr commitment, builds a Taproot commit+reveal tx pair, mines a txid prefix `4242` (max 400 000 attempts in `publisher.rs::inscription_txs`), broadcasts both txs, then calls `account_node.rs::receive_coin` to deliver the coin to the recipient -- **Tests:** `router.rs::tests::commit_missing_body_returns_error`, `commit_nonexistent_proof_id_returns_404`. **No happy-path broadcast test** — would require a live Bitcoin signet/regtest - -#### Receive coin - -- **Module:** `router.rs::receive_coin_handler` → `account_node.rs::receive_coin` -- **Behaviour:** replay-protected via per-account `coin_history` SMT -- **Tests:** `account_node.rs::tests::test_receive_duplicate_coin_rejected`, `test_receive_updates_balance` - -#### Download coin proof - -- **Module:** `router.rs::get_proof_handler` → `ProofStore::get_proof` -- **Behaviour:** streams the binary serialised `CoinProof` (`Vec` from bincode) with content-type `application/octet-stream` -- **Tests:** `router.rs::tests::proof_not_found_returns_404` - -#### Claim username +### Live deployments -- **Module:** `router.rs::claim_username_handler` → `username.rs::UsernameStore::claim` -- **Behaviour:** verifies Schnorr signature over `SHA256(username || pubkey || timestamp)` (5 min skew); persists to the Postgres `usernames` table via `db::claim_username` (`INSERT … ON CONFLICT DO NOTHING`) -- **Tests:** `router.rs::tests::claim_username_*` (3 tests) + `username.rs::tests::*` (8 tests covering valid charset, duplicates, persistence) +| Environment | URL | Bitcoin chain | Image | +| --- | --- | --- | --- | +| **PRD** | [api.zkcoins.app](https://api.zkcoins.app) | Mainnet | [`zkcoins/node:latest`](https://hub.docker.com/r/zkcoins/node/tags?name=latest) | +| **DEV** | [dev-api.zkcoins.app](https://dev-api.zkcoins.app) | Mutinynet | [`zkcoins/node:beta`](https://hub.docker.com/r/zkcoins/node/tags?name=beta) | -#### Resolve username - -- **Module:** `router.rs::resolve_username_handler` → `username.rs::UsernameStore::resolve` -- **Behaviour:** if exact username unknown, falls back to hex prefix matching against known addresses.

Metadata returned for known usernames; callback returns a phase-2 error (not wired to a real BOLT-11 invoice generator yet) -- **Tests:** `router.rs::tests::lnurlp_known_address_returns_pay_request`, `lnurlp_unknown_user_returns_404`, `lnurl_pay_callback_returns_phase2_error` - -#### Bitcoin block scanner - -- **Module:** `scanner.rs::scan_for_inscriptions` / `InscriptionScanner::scan_from_block`. Loop spawned from `main.rs::main`. State saved between runs in `data/latest_block.bin` -- **Behaviour:** subscribes to the Esplora WebSocket (`scanner_ws.rs`, `ESPLORA_WS_URL`) for new tip events; drains the resulting mpsc channel in `scanner_runtime.rs`, walking forward through `block_status.next_best`; filters txs by txid prefix `4242`; extracts Taproot inscription content via `extract_inscription_content`; deserialises as `Commitment`; calls callback in `main.rs` which verifies the signature and updates state. Polling was removed in [issue #84](https://github.com/zk-coins/node/issues/84); see [CONTRIBUTING.md § "No polling — events only"](./CONTRIBUTING.md#no-polling--events-only) for the CI lint that enforces this -- **Tests:** `scanner.rs::tests::parse_valid_inscription_into_commitment`, `reject_invalid_inscription_data`, `verify_commitment_signature_after_deserialization`, `parse_multi_chunk_inscription`. **No integration test** with a real Bitcoin block - -#### State persistence (SMT/MMR write) - -- **Module:** `state.rs::State::update` + scanner callback in `main.rs` → `db::persist_state_tx` -- **Behaviour:** on each verified commitment: append SMT root to MMR, then atomically upsert the SMT bytes, MMR bytes, and last-processed block hash inside a single `BEGIN; UPSERT; UPSERT; UPSERT; COMMIT` against Postgres (issue #11 fix). Replaces the pre-migration `smt.bin` / `mmr.bin` / `latest_block.bin` sibling files -- **Tests:** `state.rs::tests::*` (9 tests covering single + multiple updates, persistence roundtrip, proof generation/verification, empty MMR edge cases) - -#### Taproot inscription broadcast and Publisher UTXO lookup - -- **Module:** `publisher.rs::create_and_broadcast_inscription`, `inscription_txs`, `broadcast_inscription_txs`, `get_publisher_utxo` -- **Behaviour:** `inscription_txs` mines the commit txid prefix `4242` (uses random nonce loop, up to 400 000 attempts). `get_publisher_utxo` filters Esplora UTXOs for the publisher's Taproot address, requires ≥ 800 sats -- **Tests:** **none** — would require a live signet/regtest node and a funded publisher key - -#### Planned - -- **Explorer endpoints (`/api/stats`, `/api/nullifiers`)** — to power the `zkcoins.space` companion app -- **Light client support** — let wallets verify nullifier set membership without scanning the chain themselves - -### Configuration - -| Variable | Default | Effect | -| ----------------- | -------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------- | -| `IS_MAINNET` | _(required, no default)_ | Exact string `true` or `false` — anything else panics. PRD sets `true`, DEV sets `false`. Drives the `Network` enum (Mainnet vs Signet) used for address derivation. Truthy values like `1`, `TRUE`, `yes` are rejected to prevent silent misconfiguration. | -| `ESPLORA_URL` | _(required, no default)_ | HTTP Esplora endpoint for the chain this stage serves.

Empty string is treated as unset. | -| `NETWORK_NAME` | `Mutinynet` / `Mainnet` | Human-readable name returned by `/api/info`. Default depends on `IS_MAINNET`. Purely cosmetic — has no behavioural effect on the scanner, publisher, or address derivation. | -| `USERNAME_DOMAIN` | _(required, no default)_ | External hostname returned by `/api/info`. The client renders `@` from this. **Node panics on startup if unset.** PRD sets `zkcoins.app`, DEV sets `dev.zkcoins.app` — silent fallback would let a misconfigured stage reproduce the cross-network routing bug (#95) | -| `PUBLISHER_KEY` | _(required, no default)_ | 32-byte hex private key for inscription publishing. Node panics on startup if unset. On `IS_MAINNET=true` an additional check refuses the well-known test key. | -| `RUST_LOG` | `info` | Log level | - -**Why so many required env vars.** Earlier versions of this table listed Mutinynet defaults for the three chain-shaping vars (`IS_MAINNET`, `ESPLORA_URL`, `ESPLORA_WS_URL`). They were silent footguns: a Mainnet deployment that forgot one would scan Mutinynet while answering `/api/info` as Mainnet, with `/health/ready` green throughout (5-s HTTP retry loop on the scanner — issue #84). On the Mutinynet path the WS default coupled the deploy to a public third-party host we do not operate.

The wallet never holds an HTTP connection across the ~5 s prove call; each step is a separate poll-friendly request: - -1. **`POST /api/jobs/send`** (with `Idempotency-Key` header) — admit the send job. Returns `202` + `{job_id, status: "queued"}` immediately. The dispatcher picks the row up and runs the ZK prove. -2. **Poll `GET /api/jobs/:id` every ~2 s** — wallet observes `queued → proving → awaiting_signature`. When `status = awaiting_signature`, the body carries `proof_id` so the wallet can `GET /api/proof/:id` to download the proof, sign `Schnorr(hash_concat(account_state_hash, output_coins_root))` with the BIP-32 key at `numPubkeys`, and... -3. **`POST /api/jobs/:id/commit`** — attach the signed commitment. Returns `200` + `{status: "broadcasting"}`. The dispatcher broadcasts the Taproot inscription and `state.update`s the recipient; the next poll observes `status = completed` with the cached result body. - -Mint follows the same admit-then-poll pattern (`POST /api/jobs/mint`) — single-phase under the hood because the node holds the minting key, so `awaiting_signature` is skipped and the job transitions `queued → proving → broadcasting → completed` directly. - -Cancellation: `POST /api/jobs/:id/cancel` only succeeds while the job is `queued` (no prove cost paid yet).

Rationale: - Runner hosts can share their default Docker profile with unrelated workloads; a separate capped profile guarantees the CI Postgres containers neither starve nor get starved by anything else on the host (the same contention class that caused the historical sqlx PoolTimedOut flakes in db_tests). - A repo-specific runner label makes job dispatch opt-in per host: only hosts provisioned with the ci profile and toolchain pick up jobs, so a stale workflow run can never land on an unprepared host. The workflow boots the ci profile on demand (--activate=false keeps the host's global Docker context untouched) and talks to it via an explicit DOCKER_HOST. --- .github/workflows/ci.yaml | 27 ++++++++++++++++++++------- .github/workflows/deploy-dev.yaml | 2 +- .github/workflows/deploy-prd.yaml | 2 +- scripts/ci-runner/README.md | 10 +++++----- 4 files changed, 27 insertions(+), 14 deletions(-) diff --git a/.github/workflows/ci.yaml b/.github/workflows/ci.yaml index 8af83984..9cf062f2 100644 --- a/.github/workflows/ci.yaml +++ b/.github/workflows/ci.yaml @@ -205,7 +205,7 @@ jobs: if: >- (github.event_name == 'push' || github.event.pull_request.draft == false) && contains(github.event.pull_request.labels.*.name, 'ci:full') - runs-on: [self-hosted, m3-ultra] + runs-on: [self-hosted, zkcoins-node] timeout-minutes: 120 env: # All three chain-shaping env vars are required by the node @@ -274,12 +274,25 @@ jobs: - name: Prepend ~/.cargo/bin to PATH (use rustup proxy, not Homebrew Rust) run: echo "$HOME/.cargo/bin" >> "$GITHUB_PATH" - # Point `testcontainers` at the Colima socket under the runner - # user's home (see the `DOCKER_HOST` comment in the job env block - # above).

A u32 multiply now uses 1 gate vs ~30 from bit-decomposition primitives -- the efficiency foundation for a viable in-circuit secp256k1 (a from-primitives scalar_mul measured 24.5M gates). 21 ported tests pass (gate-constraint good/bad, canonicity, low-degree). * feat(program-plonky2): rebuild nonnative field arithmetic on ported plonky2_u32 gates Replaced the from-primitives nonnative (thousands of gates per mul_mod, 24.5M for one scalar_mul, non-viable) with plonky2-ecdsa's biguint + nonnative ported onto the efficient u32_lib custom gates. One nonnative mul_mod is now 114 gates. Fp (Secp256K1Base) + Fn (Secp256K1Scalar) add/sub/mul/inverse verified against host num-bigint; rejects non-canonical witnesses and wrong product reductions. 10 tests pass. * feat(program-plonky2): secp256k1 curve + GLV scalar mul on efficient nonnative Ported plonky2-ecdsa curve gadgets (projective add/double, windowed scalar mul, GLV endomorphism) onto the efficient nonnative. Measured (--release): scalar_mul = 113765 gates (2^17), build 2.1s + prove 3.0s -- vs 24.5M gates and un-buildable (>67min) from-primitives, a ~215x reduction. In-circuit secp256k1 is now feasible; no proof-system version bump needed. Verified vs host secp256k1: add/double/lift_x KATs, off-curve rejection, GLV scalar_mul, mutated-witness rejection. * feat(program-plonky2): in-circuit BIP-340 verify + sign-to-contract (P1-C.b3) The transition-signature check (spec 2.1 clause 2 / 3.2), composing the efficient GLV scalar-mul + the SHA-256 gadget: - in-circuit lift_x_even_y (BIP-340 even-Y point recovery) - BIP-340 verify: s*G == R + e*P (x-only, tagged-SHA-256 challenge e) - sign-to-contract opening R = R' + t*G, t = SHA256(bytes(R') || H(ProofData)) Verified against the V.8 fixture (--release): valid signature verifies; tampered s / Pk / rx are all rejected; a wrong H(ProofData) yields a different R and is rejected (S2C genuinely binds the proof). Measured: 361528 gates (2^19), build 76s + prove 102s. Completes the in-circuit foreign-field crypto (P1-C). * fix(program-plonky2): constrain foreign-field soundness gaps (cross-vendor review) - F1 (potential BLOCKER): GLV sign flags k1_neg/k2_neg were allocated with add_virtual_bool_target_unsafe (unconstrained), which via conditional negation + an MSM with no on-curve check could admit an off-curve point and break BIP-340 soundness. Swapped all boolean selectors to _safe (assert_bool); 0 unsafe remain. Inherited from upstream plonky2-ecdsa; missed by the honest-witness functional tests. Regression test glv_decomposition_rejects_non_boolean_sign_flag confirms a non-boolean flag now fails to prove. - F2: assert signature scalar s != 0 (BIP-340 requires 0 < s < n). - F4: range-check div_rem_biguint quotient limbs to u32. Honest cases still pass (V.8 valid-verify, scalar_mul vs host, tampered s/Pk/rx rejected); +4 gates. Hardens P1-C. * feat(program-plonky2): P1-D.1 compliance circuit skeleton In-circuit AccountState/Coin/ProofData targets, variable-length serialize(AccountState) -> ash matching host shared::spec_v1 byte-for-byte (overwrite-mode absorption handled via per-count candidate select, verified on a partial 3/32 active-slot account), output-coin construction + ocr (CoinsRoot), and the 40-element public-input layout (ProofData 28 + consumed_pubkey 8 + network_id 4) with compile-time network binding. Host parity verified for ash/coin.identifier/ocr/address; wrong network rejected. Skeleton: 50256 gates, build 1.2s + prove 1.1s. Foundation for clauses 1-10. * fix(program-plonky2): config-aware u32 range-check batching for pinned config range_check_u32_circuit now splits a range check into <=7-limb batches when the CircuitConfig's num_wires cannot hold a wider U32RangeCheckGate (8 limbs = 136 wires > the 135 of the SS1.7.9-pinned standard_recursion_zk_config), so the whole secp256k1 nonnative stack builds+proves under the pinned config, not only standard_ecc_config. Under ecc-config (136 wires) no split triggers, so existing layouts are unchanged. Adds a pinned-config proving test (curve_glv_scalar_mul_fits_standard_recursion_zk_config; scalar_mul 116765 gates). Also corrects the div_rem noncanonical-quotient test to assert verify()-rejection (plonky2 validates witness consistency in verify(), not prove(); the quotient range-check was already sound). No constraint logic changed. * feat(program-plonky2): P1-D.2 compliance signature binding (clauses 2/4/2a-c) Wires into the compliance circuit, under the SS1.7.9 standard_recursion_zk_config: - clause 2: BIP-340 verify of txn_sig over the per-network m_state by Pk_i (== prev.current_pubkey), sign-to-contract R = R' + t*G with t = SHA256(R' || H(ProofData)), and npk_commit binding - clause 4: nk_commit == Hc(NkCommit, nk); per-input nf = Hc(Nullifier, nk||id); pairwise-distinct nf; inr = NullifiersRoot Merkle root - clause 2a/2c: input recipient == owner; in-circuit coin.identifier recompute Verified (--release): valid transition proves+verifies; every negative case rejects (wrong sig / Pk_i / npk_commit / nk / duplicate nf / wrong input coin.identifier); host parity for nf/inr/nk_commit/H(ProofData). 13 compliance tests pass. Circuit (skeleton+signature): 440983 gates, ~58s build+prove. * feat(program-plonky2): P1-D.3 conservation + mint v1/v2 + state folding + coin-history Extends the compliance circuit with: - clause 3: per-asset wide-u128 conservation In(a)+Mint(a) >= Out(a) (exact non-modular; a u128 wraparound is rejected); amounts range-checked - mint (SS6.5): v1 + token-standard-2 (creator binding, AssetId/AssetIdV2 + terms_hash derivations, v2 cap check amount<=cap_total, v2 genesis binding) - clause 7: new-account-state balance folding new=prev-In+Self (+Recv later), no underflow, zero-entry removal, send_counter++, key rotation, ash recompute - clause 8: in-circuit CoinHist SMT update (0->1 admit, 1->2 spend, sequential two-root over witnessed paths, replay guard) matching host byte-for-byte 31 compliance tests pass (valid v1/v2 mints + conservation/wraparound/ underflow/bad-mint/cap/spend-absent/readmission-replay negatives + host parity). * feat(program-plonky2): P1-D.4 cyclic PCD recursion + NAV + predecessor anchoring (clause 1) Makes compliance circuit C recursive: - cyclic recursion: C verifies its own previous proof (bootstrapped CommonCircuitData fixed-point + a hand-written zk-safe dummy circuit, since plonky2's vendored dummy_circuit asserts !zero_knowledge and cannot be used under the mandated standard_recursion_zk_config); InitialProof uses the base dummy branch, AccountUpdateProof verifies the real prev_proof - conditional-NAV: nav_commitment == Hc(NavCommit, Hc(NfLog/Root,size||mth)||rand); prefix(prev.nav in w.nav) via in-circuit RFC-6962 consistency (nflog_consistency) - predecessor-nullifier anchoring: (Pk_prev,R_prev) RFC-6962 inclusion in w.nav, R_prev S2C-opens H(prev.ProofData), Pk_prev == prev_proof.consumed_pubkey Verified: a genuine 2-hop cyclic chain (InitialProof->AccountUpdateProof) proves; 6 anchoring negatives reject (forged prev proof / wrong nav_commitment / non-prefix nav / key substitution / wrong S2C opening / pos out of range); 39 compliance tests pass. Recursive circuit: 1048576 gates (2^21), build ~18-26min + prove ~10-11min under the zk config. * compliance: add clause 10 received-coin admission — full circuit C Complete the compliance predicate C with clause 10 (the receive path): per-received-coin cyclic recursion over each creating_proof (MAX_RX_COINS=4), coin binding to the creating proof's output_coins_root, cross-account NAV prefix, and creating-nullifier key+leaf anchoring (Pk_create==consumed_pubkey, R_create S2C-opens H(creating.ProofData), leaf included at pos_create1); they do not enter clause-3 conservation. Inactive slots are packed at the tail and contribute zero to every value-bearing constraint. Full C: 1,403,783 gates, degree_bits=21; all 10 clauses wired. 40/40 release tests pass (valid receive proves, six clause-10 negatives reject). * balance: add C_balance balance-attestation circuit (§5.7) Add the non-cyclic balance-attestation circuit C_balance. It verifies one compliance proof under C's constant verifier data, pinning the C proof's cyclic verifier-data public-input tail to C's canonical verifier data in-circuit (the equivalent of check_cyclic_proof_verifier_data), and proves the §5.7 statement: S.owner==subject, one asset's balance, ash(S) bound to pi.new_account_state_hash, the sign-to-contract anchor on R_anchor, Pk_anchor==pi.consumed_pubkey, prefix(nav ⊑ nav_ceiling), and network_id. Reuses C's account hashing, NAV consistency, and S2C gadgets via minimal pub(crate) accessors; C's constraints and circuit_digest are unchanged (gate count identical at 1,403,783 on rebuild). Public inputs: 60 elements per §2.5 (subject, asset_id, balance, nav_ceiling, size_ceiling, anchor{txid,block_hash,height,Pk_anchor,R_anchor}, network_id). size_ceiling uses a canonical (< ORDER) 64-bit decomposition bound to the same target committed in nav_ceiling. C_balance: 193,437 gates, degree_bits=18. Balance tests: the valid attestation proves and verifies; eight negatives reject (six normative statement checks plus a tampered verifier-data tail and a non-canonical size_ceiling). * prover: add production prover bridge for C / C_balance Add script-plonky2 prover_bridge: a host-facing API that assembles the compliance (C) and balance-attestation (C_balance) witnesses from spec_v1 host structures, produces genuine proofs, and verifies them under the mandatory acceptance obligations. prove_transition proves an InitialProof or AccountUpdateProof from a TransitionWitness, recursively verifying the predecessor and each received coin's creating proof, and cross-checks the proved ProofData, consumed_pubkey and network_id against the host-derived values. verify_transition performs both obligations: data.verify plus check_cyclic_proof_verifier_data (verify alone is insufficient for a cyclic proof). prove_attestation and verify_attestation cover C_balance. Doc-comments state the out-of-circuit host preconditions (canonical NAV, first-occurrence anchor) the node must enforce. Exposes a NonNativeTarget::value accessor (no constraint change). Circuit gate counts unchanged: C=1,403,783, C_balance=193,437. Prover-bridge end-to-end test proves and verifies a genesis/mint, a send, and a balance attestation, and rejects a tampered cyclic verifier-data tail; the existing compliance (36) and balance suites pass. * prover: add host BIP-340+S2C signature preflight to prove_transition Replace a comment that falsely claimed a pre-proving network/signature check with a real host-side BIP-340 + sign-to-contract verification, so an invalid or wrong-network signature fails fast instead of wasting a full proving run (the circuit C remains the authoritative in-circuit verifier). verify_transition_signature reconstructs R = R' + t*G (t = SHA-256(R' || H(ProofData))), requires the even-y S2C nonce to match the signature's R, and checks the BIP-340 equation s*G == R + e*P with e over m_state. It reuses the same canonical x-only even-y lift the circuit applies to R', so it accepts exactly the signatures C accepts. Promotes field_bytes/is_odd/tagged_hash to module scope and makes sha2 a normal dependency. Prover-bridge end-to-end release test passes (1646s). * engine: add in-memory state-transition engine (P1-E.2) Add script-plonky2 state_engine: the in-memory zkCoins state model (per-account AccountState + CoinHist, the global NfLog accumulator) and the §2.3 two-phase transition lifecycle (request -> awaiting_signature -> finalise) for mint, send and receive, driving the P1-E.1 prover bridge. begin_mint/begin_send/begin_receive build the transition witness and surface the six ProofData fields; finalise proves via the bridge and applies the new state transactionally. verify_incoming_transition runs both acceptance obligations plus the canonical-NAV / size_final check against the local NfLog. Hardening (a correctness review found these): multi-input sends and batched receives build sequential intermediate CoinHist roots; NfLog apply is staged and committed only after all checks pass (no partial mutation on error); finalise binds the pending envelope (owner/mode/nav_opening/prev-state) to the witness before proving; wrapper ProofData is re-extracted from the proof and compared before it is trusted; token-standard-2 mint is rejected loudly until the request API carries an explicit non-owner recipient. Circuit gate counts and digests unchanged; a benign pub(crate) re-extract helper is added to the bridge. Tests: single-input send end-to-end proves and applies; overspend, envelope mismatch, transactional rollback on duplicate, forged-wrapper rejection, multi-input sequential roots and initial receive all pass (8/8). * half-agg: add NISSHAC half-aggregation and AggregateStateNullifierV3 codec (P1-F.1) Add script-plonky2 half_agg: the NISSHAC half-aggregation crypto (§1.7.10 / §3.3) over BIP-340/secp256k1 and the AggregateStateNullifierV3 inscription payload codec (§3.5). aggregate_sig derives z and the per-index coefficients a_j and returns s_agg = sum(a_j * s_j) while retaining every (Pk_j, R_j). aggregate_verify runs the single multi-scalar relation s_agg*G == sum(a_j * (R_j + e_j*Pk_j)). comm_retrieve / comm_verify implement the receiver's sign-to-contract opening R == R' + t*G with the unreduced-tweak rejection. verify_single is the plain BIP-340 check. Canonical x-only/scalar encodings are enforced everywhere; off-curve, infinity, non-canonical, or over-order values are rejected. AggregateStateNullifierV3 serialize/deserialize follows the §3.5 layout (42-byte header + format 0x00 raw / 0x01 half-aggregated body) with fail-closed parsing (rejects wrong version/format, count over/underrun, trailing bytes, truncation, and format 0x00 count != 1). The Taproot envelope and the block_anchor-vs-inclusion bound are the scanner's job (P1-F.2 / P1-G). Reuses the prover bridge's BIP-340/S2C EC helpers (promoted to pub(crate)). Tests: NISSHAC completeness (k=1,2,3), tamper/non-canonical rejection, comm_verify round-trip, payload round-trip and malformed-payload rejection, and a measured payload-size report (k=1:138B, k=10:714B, k=100:6474B). 7/7 pass. * inscription: add Taproot commit/reveal construction and payload extraction (P1-F.2) Add script-plonky2 inscription: builds the §3.5 Taproot commit/reveal pair that carries an AggregateStateNullifierV3 payload in an OP_FALSE OP_IF envelope, and the fail-closed payload-extraction primitive scanners use to read it back. build_envelope_script splits the payload (marker 0x42 0x42) into minimal pushes of at most 520 bytes inside a single OP_FALSE OP_IF ... OP_ENDIF leaf. extract_payload_from_input implements §3.5 exactly: it ignores the annex, rejects key-path spends, decodes the control block and verifies it commits the executed Tapscript to the prevout, then concatenates the envelope pushes and returns the payload iff it begins with the marker. Fail-closed: a non-minimal push, an over-520-byte push, a non-data opcode in the body, or a second marker envelope in one leaf makes that input carry zero nullifiers. The block_anchor and first-occurrence checks remain the scanner's job (P1-G). Adds rust-bitcoin 0.32.5. Tests (in-memory, no node): commit/reveal round-trip extracts and deserializes the aggregate; a large payload splits across bounded pushes and round-trips; every fail-closed shape is rejected (8/8). * publisher: add half-agg batch publishing over a live Bitcoin node (P1-F.3) Collects state-nullifier signatures, half-aggregates them into an AggregateStateNullifierV3, inscribes the payload into a Taproot commit/reveal pair and broadcasts both to bitcoind over cookie-authenticated RPC. The commit output's internal key is the BIP-341 NUMS point, so its key path is provably unspendable and the envelope leaf is the only way to spend it. Funding is restricted to segwit inputs: build_inscription emits a commit transaction with an empty funding witness while the reveal already references commit_txid, so a legacy scriptSig would change that txid when signed and invalidate the pre-built reveal. Fees are sized in two passes against the measured vsize of the signed transactions, with a drift assertion before broadcast. Covered by unit tests for the guards and by a live regtest round trip that broadcasts, confirms and reads the payload back out of the mined reveal. * publisher: close six review findings before freeze Critical: an oversized batch could broadcast a commit whose reveal exceeds Bitcoin's weight limit. Since the commit output's key path is the NUMS point and its only leaf would then be unminable, that value is permanently unspendable. Both transactions are now checked against MAX_STANDARD_TX_WEIGHT before anything is broadcast, and max_half_agg_members_for_standard_reveal reports the batch size that fits. Batches are never auto-split: composition decides which nullifiers land together and stays with the caller. The aggregate is now verified with aggregate_verify against the publisher's own network m_state before any transaction is built. Previously only the canonical point and scalar encodings were checked, so a member signed for a different network was inscribed and paid for while the scanner discarded the whole batch. The block anchor is now the oldest member's verified build tip, per the section 3.5 rule that it must be an ancestor of, or equal to, that tip. Members carry their proof-time tip in BatchMember. A stale tip fails loudly rather than being silently replaced with a fresher one. fetch_reveal_payloads is removed in favour of fetch_reveal_payload_details: the short form dropped per-input extraction errors, making a fully malformed reveal indistinguishable from one carrying no inscription. Fee sizing is now a fixed-point iteration over fees and change topology instead of two rigid passes, so a batch whose change falls below dust after recalculation still publishes. Funding is restricted to input types with a predictable witness size (v0 P2WPKH, v1 P2TR key path), and selection walks to the next candidate when one cannot cover the final measured fees. * publisher: close five confirmation-review findings Every member's build tip is now validated against this node's chain, not just the selected one: each height must not exceed the tip and each hash must be the canonical block at that height, with the lookups cached so a large batch does not issue one call per member. The doc-comment now states plainly that build_tip is a caller assertion the publisher cannot cryptographically bind, since NISSHAC does not commit it and the payload has no per-member tip field. A dishonest submitter can overstate freshness; the scanner cannot observe that from the aggregate, so there is no consensus divergence, and closing the gap needs proof-layer tip supply. connect now compares bitcoind's reported chain against the configured network and fails loudly on mismatch. Previously a testnet-configured publisher would verify and broadcast against a regtest node while a conformant regtest scanner discarded the whole aggregate. Publication uses an effective anchor gap of 94 rather than 100, leaving six blocks of margin for inclusion delay, and the tip is re-checked immediately before the first broadcast. At the old bound a single block of delay between selection and inclusion made a batch carry zero valid nullifiers while its fees stayed spent. Funding candidates are now rejected only against their measured requirement. The provisional estimate seeds the iteration and no longer gates admission, so a UTXO that funds the real transactions is no longer discarded against an inflated estimate, and the error no longer claims a measurement that did not happen. The fee fixed point records the states it has already seen, so a repeating fee/topology pair is detected instead of relying on branches that could not fire. * publisher: close six freeze-review findings Testnet is bound to Signet exactly, as the spec pins it. The previous mapping also accepted testnet3 and testnet4, so a publisher could broadcast where no conformant testnet scanner was watching. The build-tip documentation is corrected. It previously claimed the aggregate signature covers block_anchor and that proof-time height is cryptographically bound in the per-account proof; neither is true — aggregate_verify ignores block_anchor, the coefficients cover only (R, Pk) members, and ProofData has no height field. It also understated the consequence: a submitter claiming a newer tip than the proof was built against turns a batch that the truthful anchor would have made ineligible under the gap bound into an admitted one. Scanners agree with each other, but the rule is not enforced here, so this is a trust assumption on the caller. The pre-broadcast guard now re-verifies the anchor's identity rather than only its height gap, bypassing the lookup cache. A same-height reorg during fee convergence previously passed the guard, both transactions went out, and the scanner rejected the aggregate for a non-ancestor anchor. The inclusion-delay margin moves into the configuration, validated against the maximum gap, and its effect is documented: with margin m, inclusion up to m + 1 blocks after the check still satisfies the bound, and beyond that the batch carries no nullifiers while its fees stay spent. The documentation also records that the commit transaction cannot be fee-bumped, since bumping it would change commit_txid and invalidate the pre-built reveal, so an adequate fee rate chosen up front is the only lever. Member count and reveal weight are validated before any per-member chain lookup, so an unpublishable batch costs a constant number of calls instead of one per member. Funding candidates that cannot cover the theoretical minimum are skipped arithmetically before anything is built or signed, and the number of constructed attempts is bounded and reported. Rejections are classified as measured or unmeasured, so a candidate rejected before any transaction was built is no longer reported as failing to cover measured fees. * publisher: bound anchor-selection RPC cost, correct the fee-bump note Anchor selection applied the height window only after looking up every member's claimed height. A weight-valid batch of thousands of genuinely correct historical heights therefore issued one getblockhash per height and was rejected only afterwards for staleness — finite, but hours of synchronous work against a slow node. The window is now applied arithmetically on the caller-supplied heights before any lookup, so a rejected batch costs a single tip query and an accepted one at most as many lookups as the window is wide, regardless of member count. Chain-existence and future-ness validation of every surviving member is unchanged. The commit-fee note claimed an adequate upfront fee rate was the only lever. The commit does signal RBF, and because the reveal carries no signature a replacement commit can be paired with a newly built one; the reveal can also serve as a replaceable CPFP child. The note now states that no fee-bump path is implemented here rather than implying none exists. * scanner: rebuild the nullifier accumulator from Bitcoin (P1-G) Implements the five mandated steps of section 3.6 over confirmed blocks: discover script-path inputs whose executed leaf carries a zkCoins envelope, parse and bound-check the payload, verify signatures against the per-network m_state, order the survivors by (height, tx_index, vin_index, member_index), and fold them into the accumulator by first occurrence. The anchor bound is enforced in all three parts: strictly below the inclusion height, gap at most 100, and the claimed hash must be the canonical block at that height, which is what makes strict ancestry real rather than a height comparison. A signature failure discards the whole payload rather than the offending member, as step 3 requires. Malformed inputs carry zero nullifiers and are recorded with a reason instead of aborting the block. Reorgs are handled by canonical replay against the existing accumulator, and a broken finality assumption is surfaced to the caller rather than absorbed. The RFC-6962 log and the accumulator itself already exist in shared and are consumed unchanged; this module is the Bitcoin-side bridge to them. Covered by unit tests for the bound predicate and the discovery pre-filter, and by live regtest tests that publish real inscriptions and scan them back, including a double spend of one account state across two batches and a real chain reorganisation. * scanner: separate data failures from infrastructure failures The accumulator must be a pure function of the confirmed chain, so a failure that is not derivable from chain data must never influence it. The module conflated two kinds: a malformed envelope or a failed signature is a deterministic property of block content that every honest node sees alike, while an RPC timeout or a lagging index is a property of this node's environment. Both were recorded as rejections and the block was then checkpointed, so a node that hit a transient error permanently omitted a nullifier its peers admitted. Data failures and infrastructure failures are now distinct types, and a rejection can only be constructed from the former. An infrastructure failure aborts the scan and leaves the checkpoint untouched, so the work is retried. connect now requires txindex to be enabled and fully synchronized, and rejects an activation height that disagrees with the pinned network value rather than substituting it. A scanner that cannot resolve prevouts, or that starts from the wrong origin, cannot produce a correct accumulator, so it refuses to start instead of producing a wrong one. Forward scanning verifies that each block links to the previously processed one. A reorg during a scan previously mixed blocks from two forks into one accumulator and left it undetected, and the outcome depended on how the scan was split into calls. Reorg replay is atomic: the replacement range is collected in full before any state is touched, so a failure partway leaves the scanner unchanged instead of losing a canonical nullifier on retry. Replacement-block rejections and duplicate positions are reported rather than discarded, and parent transactions and anchor hashes are cached per scan run, with the anchor cache dropped on reorg. * scanner: hold the reorg path to the forward path's guarantees The forward scan was hardened last round and the replacement path was not, so it revalidated payloads without the guarantees the forward path had gained. Both now share one block-collection implementation, so a future fix cannot land in only one of them. The anchor-hash cache was cleared only after replacement collection, so replacement blocks were validated against getblockhash answers from the fork that had just been orphaned. A payload anchored to the new block at that height was rejected while one naming the orphaned hash was accepted, and since the signature does not bind the anchor the latter is trivial to construct. The cache is now invalidated before any replacement validation begins. Replacement collection now verifies block linkage as the forward path does. A second reorg during collection could otherwise mix blocks from two forks into one replay stream, and a canonical final block left the checkpoint consistent with the live chain so nothing detected it afterwards. A reorg occurring after the last forward block could return a tip the accumulator did not reflect, which matters because membership answers are only meaningful relative to a stated tip. The reported tip is now the one the log actually corresponds to. Reorg outcomes are merged across a call with sticky finality_broken and summed displaced counts, so a shallow reorg can no longer erase an earlier finality break from the report. Replacement admissions and duplicates are reported like forward ones, and the live test now reorgs onto a replacement block that carries both a new winner and a duplicate. Atomicity is per block rather than per call: a block is fully processed and checkpointed or not processed at all, an infrastructure failure resumes at the failing block, and the error carries the completed prefix's report so nothing observed is lost. The previous per-call claim was not true. * scanner: decide anchor admissibility from the inclusion block's ancestry Anchor validation resolved getblockhash against whatever chain was active at that moment, while validating a transaction from a specific inclusion block. If the chain moved to a competing fork and back during a scan, the anchor was checked against the other fork: a valid payload was rejected, or one naming an orphaned hash admitted, and because the chain was canonical again by the final check nothing detected it and the wrong decision was checkpointed. Two nodes then disagreed permanently on entries, positions and the root. Clearing the cache when a reorg is detected could not fix this, because that interval leaves nothing to detect. Section 3.5 asks whether the anchor is an ancestor of the inclusion block, which is a property of that block's own ancestry rather than of the current tip, so the check now answers exactly that question: against the verified chain the scanner walked, and otherwise by walking back from the inclusion block, at most as far as the maximum gap. Walk results are keyed by the descendant they were derived from, so an entry cannot be reused under a different fork. Activation height is taken from the supplied network parameters instead of a compile-time constant, so mainnet and signet scanners can start at all; their pinned value is observed at deployment and published, and only regtest is fixed at zero. Duplicate handling keeps a public-key to winner-position index, replacing a linear scan over all prior survivors that a single aggregate could repeat into quadratic work. Every error path after the first committed block now carries the partial report through one exit, so a failure in a post-scan tip query can no longer discard the reports of blocks already folded and checkpointed. * scanner: verify the parameter set against its published identity The activation origin was compared against another value from the same caller, so it confirmed nothing. A scanner configured with a wrong height and a matching hand-made parameter set connected successfully while a peer using the published values started elsewhere, which is exactly the divergence the scan origin rule exists to prevent. The parameter set is content-addressed, so its identifier is the external truth: connect now requires the operator to supply the published identifier and compares it against the set's own. Any difference in any field, including the activation height, changes that identifier, so a node can no longer diverge by accident. The set's network tag must also correspond to the configured network, and regtest stays pinned to zero. The ancestry walk resumes from the deepest cached ancestor of the inclusion block instead of restarting from the block each time. Because anchor resolution precedes signature verification, one block carrying payloads with increasing anchor gaps could otherwise force thousands of synchronous block queries without holding a single valid signature. The walk cache is bounded with a deterministic eviction policy, since an evicted entry only costs a re-walk while an unbounded one costs memory an attacker chooses. Prevout lookups return the single output they need rather than cloning the whole parent transaction on every cache hit. * accumulator: maintain the log root incrementally Folding recomputed the Merkle tree head over the whole log after every admission, so building N entries cost quadratic hashing and a reorg replay repeated it. The chain scanner is exactly the bulk caller the old doc-comment warned away from, since it folds every nullifier published from the activation height onward, so the accumulator could not have synced a real chain. The root is now carried as the set of perfect-subtree roots and updated in logarithmic time per append. nflog_mth is untouched and remains the normative reference, which is also what the equivalence test compares against: the incremental head matches it byte for byte for every size from zero to three hundred and at the power-of-two boundaries where split and peak-bagging behaviour changes. Inclusion and consistency proofs verify against the incremental head unchanged, and a replay ends in the state a fresh sequential fold produces. Measured on twenty thousand entries: 298 ms incremental against a projected 980 s for the previous behaviour. * nflog: keep protocol sizes in u64 end-to-end The log verifiers took u64 sizes and narrowed them with `as usize` after the guards had already run on the untruncated values. On a 32-bit target that narrowing is silent: verify_inclusion(leaf, 0, [], 2^32+1, leaf) collapses the size to 1 and accepts, and verify_consistency(1, X, 2^32+1, X, []) collapses both sizes to 1 and accepts a non-prefix claim. This is not a hypothetical target. wasm32 has a 32-bit usize, and these primitives are the ones a wallet would compile there. Carry u64 through split_point, verify_path_range and verify_subproof instead of rejecting out-of-range values, so the defect class disappears rather than the instance. The remaining `as usize` conversions are bounded by entries.len(). No emitted digest changes; the generated vector files are byte-identical. * vectors: generate the spec's values from the reference implementation The specification pins its Poseidon-derived values as placeholders: no one may hand-author them, because a wrong vector would lead two implementations to agree on something invalid. This generates all of them from the live primitives, plus the two circuit digests the spec carries as protocol constants. Blocks: - Poseidon values (22), extended with detect_tag over the pinned V.10 fixture - circuit digests for C and C_balance, one per network tag per §589, encoded via digest_to_bytes (§1.7.1) rather than the bincode form - V.11 log vectors: mth@n, nav_root@n, twelve inclusion and five consistency paths over the spec's pinned sample-leaf sequence - V.5 transition signatures (BIP-340 + sign-to-contract) and the V.6 aggregate scalar s_agg s_agg reproduces the value V.8 already pins, which makes it the one vector in this set with an independent reference to check against. The V.11 boundary suite now feeds one fixture generator into all three consumers -- the independent RFC-6962 reference, the host verifiers, and the in-circuit gadget -- as §1.7.8 requires, covering every size bit k = 0..63 for both accept and reject. Previously it exercised only the host verifiers, and its peak-bagging block compared the reference against itself. Negative cases mutate exactly one property instead of reseeding the fixtures; cases that cannot be built that way are listed rather than dropped. The independent reference lives behind a test-fixtures feature so a normal build neither compiles nor exports a second RFC-6962 derivation path. Every value is computed; none is written by hand. * nflog gadget: represent log sizes canonically The gadget carried a log size or position as one Goldilocks target and decomposed it with split_le(x, 64). Goldilocks has p = 0xffffffff00000001, which is below 2^64, so that decomposition is not injective: the bit patterns of 1 and of p + 1 = 0xffffffff00000002 satisfy the same constraint. A malicious prover could exploit the alias directly. Bind a root computed for size p + 1, then let the verifier read the same target as 1, enter the n == 1 base case, and accept an empty inclusion path. Both decompositions are satisfiable, so an honest witness generator choosing canonical bits does not close it -- soundness is about what a prover can satisfy. Route every size-carrying target through a canonicity check, so a second representative is unsatisfiable. Sizes stay 64-bit; §2.5 sets H_MAX = 64 and narrowing the supported range would not have been a fix. The soundness test injects the p + 1 bit assignment onto the wires directly, which the high-level witness API cannot express, and asserts the proof fails. This changes the shape of C and C_balance and therefore their digests. That is possible only because those digests are still in the specification: once pinned, §1.7.8 makes any change to the frozen circuit surface a new protocol version. Host-side vectors are unaffected and byte-identical. * nflog boundary suite: count only what actually ran, and build the missing negatives The peak-bagging block incremented host_accept and gadget_accept without calling either implementation, and compared the reference against itself. All 192 peak cells were credited to three layers while one layer had run. A count that overstates coverage is worse than a reported gap, because it stops anyone from looking. Peaks now reach host and gadget through the consistency path that consumes them. What genuinely cannot reach all three is counted separately as ref_only rather than folded into a number that reads as three-layer agreement. The suite also skipped 131 negatives as unconstructible because swapping is a no-op on a single peak or chunk. NL-B2 also permits a root to be dropped or duplicated, which changes the bagging property alone and rejects cleanly, so those cases exist now -- including every adjacent (2^k, 2^k+1) consistency case with one mth_a chunk. Honest counts, per layer actually executed: accept ref=631 host=631 gadget=631 (+191 reference-only, reported) reject ref=2260 host=2260 gadget=2260 (+132 reference-only, reported) Remaining skips are 71, each genuinely unconstructible at its size. No layer disagreed, and the new cases surfaced no regression from 302fe30. * circuit: carry protocol sizes as two u32 limbs end to end The canonicity check added in 302fe30 closed the split_le alias by proving the reconstructed integer is below p. That makes the decomposition unique, but it also makes every value in p .. 2^64-1 unwitnessable -- 2^32-1 valid protocol values. §2.5 sets H_MAX = 64 and the log supports sizes through 2^64-1, so a size of exactly p became a legitimate value with no constructible proof. One soundness hole traded for a liveness hole. The test suite could not see it: its largest size is 2^63+1, and p is above 2^63, so the entire affected band lay beyond what 36 minutes of tests reached. Introduce U64LimbsTarget { lo, hi } with both limbs range-checked to 32 bits, and keep protocol numerics in that form through comparison, borrowing subtraction, the split-point derivation, the bit-driven recursion and the big-endian byte encoding. Deriving limbs from a single field target after the fact is not enough -- the moment a u64 passes through one Goldilocks element, either the alias or the narrowing returns. Public input layout is unchanged: C stays at 108, C_balance at 60. Sizes, positions and counters are private; size_ceiling was already two public u32 and now has the limbs as its representation rather than a derived view. New tests cover the previously invisible band -- n at p-1, p, p+1 and 2^64-1, with positions and adjacent consistency pairs -- and a non-canonical limb outside u32 still rejects. Cheaper as well as more correct: the gadget drops from 6669 to 1825 gates for inclusion and 6849 to 2005 for consistency, degree bits 13 to 11, because two 32-bit range checks cost less than a 64-bit split plus a comparison against p. smt.rs and main.rs carry the same defect class and are deliberately untouched; neither is reached by C or C_balance. Host-side vectors are byte-identical. * vectors: regenerate the circuit digests after the limb redesign The digest is a function of the circuit's shape, so the canonical size representation changed all six values. The previous set described a circuit that no longer exists. C drops from 1403783 to 1382481 gates and C_balance from 193437 to 191268; degree bits are unchanged at 21 and 18. The saving exceeds the isolated gadget's 4844 because the inclusion and consistency gadgets are instantiated several times per proof. Build: 3652s. * node: add v1.1 persistence and a flag-gated path to the StateEngine First cutover block. The StateEngine was in-memory only, while the running node persists the retired model: global SMT and MMR, account blobs carrying the legacy Proof, commitment payloads in pending_inscriptions. The v1.1 model needs different state entirely -- the NfLog accumulator, per-account CoinHist, and ComplianceProof blobs -- and the old global structures have no successor by design. Everything here is additive. New tables alongside the existing ones, nothing dropped, nothing migrated; a v1.1 node runs against a fresh database. The legacy path stays the default and is unchanged. Selected by ZKCOINS_PROVER=v11; unset, empty and 'legacy' all resolve to the legacy path, tested without mutating the environment. If the v1.1 path is selected and a component it needs is missing, it fails loudly rather than falling back -- a node that silently proves with the wrong circuit would look healthy while producing proofs no v1 verifier accepts. The nullifier index is keyed by Pk rather than by (Pk, R), matching §3.6 first-occurrence folding and the NfLogAccumulator rather than a generic seen-set. Restart identity is what the persistence tests assert: after a full reload, the NfLog root, its size, and every account's CoinHist root are byte-identical. A test that only round-trips blobs would not establish it. ProverBridge::new becomes lazy so persistence tests need no circuit build; digests and proofs are still constructed on demand. circuit_digest_bytes() is exposed on the bridge for self-heal parity, using the canonical §1.7.1 encoding rather than the legacy bincode form. * node: make the shadow flag honest and close four persistence defects A review found the flag claimed more than it did. ZKCOINS_PROVER=v11 reported 'Prover mode: v11' and then unconditionally built the legacy Prover, loaded legacy state, ran legacy self-heal and exposed legacy REST proving. Deferring the prover swap to stage 3 is the plan; claiming it had happened is not. The flag is now ZKCOINS_V11_SHADOW and both its name and its startup message say what it does: v1.1 state is maintained alongside the legacy path, proving stays legacy. Boot now validates the pinned consensus parameters. It previously accepted any non-negative activation height without checking the parameter set against its published identity -- the same shape of empty check the scanner already avoids by carrying an independently pinned, content-addressed identifier. It uses that mechanism rather than a second one. Reads are snapshot-consistent. The write path already replaced all tables in one transaction, but a concurrent load could observe old and new rows together and reconstruct a state that never existed. Loading now runs at REPEATABLE READ, so a reader sees either the whole old or the whole new state. A database with v1.1 rows but no meta row used to load as an empty engine. That is a silent fallback producing a plausible wrong state, so it now fails loudly; genuinely empty still loads empty. The tip cursor stores the block hash beside the height, so two forks at the same height are distinguishable after a reload. Migration 0019 is unreleased and was edited in place. Found while fixing: from_engine would have zeroed the tip hash on every adapter persist, so reloads could drop it. * style: apply rustfmt to the rest of the workspace Formatting only, no semantic change. Earlier blocks were committed without a formatting pass, so 'cargo fmt --all --check' failed across files unrelated to the current work. Keeping this separate leaves the preceding commit readable. * node: run the v1.1 publisher and scanner as an exclusive alternative stack Two publishers existed side by side and the binary used only the legacy one. It writes a bincode commitment, and the scanner callback folds that commitment into the global SMT, so the double-spend enforcer is first-write-into-SMT. The v1.1 stack publishes AggregateStateNullifierV3 with NISSHAC half-aggregation, and its enforcer is the NfLog accumulator with §3.6 first-occurrence folding. Those are different on-chain objects with different double-spend semantics, so the two must never reach the same accumulator or the same database. That is enforced structurally rather than by convention: a stack marker is persisted, and a node refuses to boot when the marker and the selected stack disagree -- legacy data with the v1.1 stack, or v1.1 data with the legacy stack, both fail with an explicit refusal. Behind the shadow flag the node now publishes via script-plonky2 and scans into the NfLog. The fold is tested against a shuffled multi-member inscription including a duplicate Pk, where first occurrence must win. Deliberately still open, to be closed by later blocks: the prove path still produces commitments under the flag, so publishing is refused rather than silently downgraded until stage 3 wires it; receive remains legacy bookkeeping (G3); wallet signing is untouched (G4). Operational note the plan missed: the node reads the chain through Esplora, while the v1.1 scanner and publisher speak bitcoind cookie RPC. A v1.1 node therefore needs a bitcoind, which is a deployment requirement rather than a code gap -- the publisher has needed a wallet-capable node since it was built. * node: bind the stack separation to the database and survive a restart across a reorg A review found the separation was advisory. The boot check knew two tables, four writers bypassed it, and the marker was claimed in a transaction of its own before validation -- so the window between checking and writing was exactly where the bad states arose. The marker is now validated inside the same transaction as every write of v1.1 scan state, and a missing marker is an unconditional refusal whenever either stack's data exists; only a genuinely empty database may claim a stack. Publishing refusal was not total either. create_and_broadcast_inscription was guarded but resume_pending_inscriptions was not, so a v1.1-claimed database holding an old or injected pending row could still broadcast a bincode commitment through Esplora. Every publishing entry point is guarded now, recovery included. The worst defect was invisible to any test that did not look for it. Each boot built a fresh scanner at activation_height with an empty folded_keys set, so a reorg that happened while the node was down went unnoticed: the new canonical stream was folded into an NfLog still carrying the old fork's first-occurrence winners, diverging from consensus with nothing raising an alarm. Boot now reconciles the persisted tip hash against the chain before folding anything, and replays from the last common ancestor rather than continuing. The test asserts the restarted node reaches the same accumulator a continuously running node would hold. finality_broken is honoured rather than ignored, and readiness reflects the v1.1 scan state when that stack is claimed. The full suite passes at 479 tests once the environment it needs is set (PUBLISHER_KEY, IS_MAINNET, ESPLORA_URL, ESPLORA_WS_URL, USERNAME_DOMAIN). The 13 failures reported earlier are pre-existing: lazy statics panic without those variables and poison the tests that follow. connect_v11_publisher still has no call site in the binary; wiring it is stage 3, after which bitcoind with txindex and a wallet becomes a deployment requirement. * node: fail-stop on unrecoverable reorgs, and guard broadcast structurally A third review round found the reconciliation was cosmetic. Boot compared only the canonical hash at the persisted tip height and, on any mismatch, replaced everything, cleared the replace flag and reported ready. It never resolved the persisted hash itself, never found a common ancestor, never measured depth, and never noticed displaced final positions -- so an offline reorg of six blocks or more was silently repaired. §3.9 requires fail-stop for displaced finality, not recovery. Boot now resolves the persisted tip, walks back to the last common ancestor and measures the depth. Below activation height, beyond the recoverable limit, or with any previously final position displaced, it refuses: no fold, not ready, explicit error. Only a shallow non-final reorg replays from the ancestor. Emptiness was decided over one table while three others carry durable legacy state, so a legacy database could look empty and be claimed by v1.1. It is now decided over every durable table of both stacks, in the same transaction that claims the marker. Two more public broadcast paths were unguarded. Rather than patch entry points a third time, the guard moved to the internal choke point every path traverses before the client broadcasts, so a new caller cannot omit it. The reorg test's oracle was circular -- it built its 'continuous node' by calling the replace path under test. It now folds the canonical stream sequentially by first occurrence instead, so the two sides can disagree. Full suite: 484 passed. * node: close the claim race, make an unguarded client unobtainable, stop over-refusing Three defects from the fourth review round. The claim could still race a legacy writer: the emptiness check saw both stacks empty, a concurrent legacy write committed SMT/MMR state, and the claim then committed mode=v11 over a database that was no longer empty. All three legacy writers -- persist_state_tx, persist_state_and_mark_complete_tx and insert_root_index -- now carry the same capability check inside their own transaction, so no interleaving can produce a mixed database. The broadcast guard was not a choke point for the third time: boot recovery and the recover_inscription binary both reached the client directly. Rather than guard two more call sites, the client itself is now the guard. connect(url) is the only public construction and checks before building; the inner Esplora client is private with no escape hatch. Possessing a broadcast-capable client therefore implies the check already happened, including from a separate binary. The reconciliation had become too strict in two places, which is the failure mode that closing a soundness hole tends to produce. A one-block reorg of the activation block has its ancestor at activation_height - 1 and was refused as 'below activation', although below activation the NfLog is empty by §3.6 and a rescan is exactly a replay from activation. And an RPC node whose tip sits below the queried height was treated as divergence -- 'I do not know yet' read as 'the chain says otherwise'. Behind is now distinguished from diverged: an incomplete view refuses rather than guessing in either direction. Still refused, deliberately: depth beyond §3.9's limit, an unresolvable or pruned tip, no common ancestor down to genesis, an ambiguous cursor, and any RPC failure. Full suite: 488 passed. * node: separate transient from fatal, and put the raw client out of reach Fifth review round on this block. Reconciliation and the first scan observed different chains: reconciliation ran before the scanner's first pass, so a reorg landing between the two was invisible -- the first report carried no reorg and the node took the forward path. Both are now bound to one observation. The recovery binary still obtained an unguarded client, and esplora-client remained a direct dependency with raw clients built in production code. While the raw type is reachable, a wrapper is a convention rather than a boundary, so the dependency now lives behind a module that exposes only the guarded type. The test exercises the binary's own path instead of setting the flag by hand. Two mutators bypassed the claim invariant: claim_stack_scan_mode, a public 'test helper' compiled into production that inserted the marker without checking either stack, and reset_proof_dependent_state_tx, which deleted all four legacy tables with no capability check. The response to a lagging bitcoind was wrong even though the reasoning was right. Treating an incomplete view as 'not divergence' is correct, but the node then errored out and marked finality broken, so a node whose bitcoind was still syncing could not start at all and a transient lag looked like a finality violation. Reconciliation now returns a typed outcome: Ready for fresh, still canonical and shallow reorg; RetryableIncompleteView for an RPC behind or unreachable, which stays unready and backs off without touching the deep-reorg flag; and a hard error only for an unresolvable tip, a missing ancestor, depth beyond §3.9, or RPC infrastructure failure. Found while fixing: self-heal under the v1.1 claim no longer wipes legacy state, it only updates the digest. Full suite: 493 passed. * node: reconcile against immutable ancestry, and enforce the client boundary by compilation Sixth review round on this block. The boot observation had an ABA race. The first scan captured chain A, then reconciliation queried the mutable live chain height by height, so an A→B→A sequence passed every check: persisted state from B, scan on A, reconciliation seeing B and reporting still-canonical, the chain returning to A before the final pin. Stale B fold keys were then seeded and A survivors appended, and because the checkpoint already read A no later scan reported a reorg -- the mixed accumulator was permanent. This class was solved once before here. The scanner's anchor validation had the same defect, and two fixes based on better cache handling both failed because A→B→A leaves no detectable reorg. The answer then was to validate against the immutable ancestry of a fixed block rather than the live tip, and it is the answer now: classification runs purely over the captured scan tip's ancestry, using getblockcount and getblockheader by hash. Sampling the live tip twice is not an ABA defence and is kept only as a secondary 'tip moved' retry. Self-heal under a v1.1 claim preserved exactly what a reset exists to clear. Skipping the legacy SMT/MMR wipe is correct and stays; keeping stale proof-bearing account rows was not, and came from my own instruction last round being too broad. A v1.1 reset now clears legacy account and proof state while leaving the structures v1.1 does not use untouched. A genuinely behind node was classified fatal: the persisted hash was resolved before checking whether the live node had reached that height, so a restored bitcoind that does not know the hash yet failed before it could report being behind. The order is reversed; an unknown hash is fatal only once the node is at or beyond that height. The client boundary was organizational. esplora-client stayed a normal dependency of the node package, so every binary target could construct a raw client, and the boundary test searched text rather than types. The dependency now lives in a separate esplora-bound package that exports only the guarded wrappers, and a compile-fail test asserts the raw type is not in scope. Full suite: 493 passed. * node: require a witness to construct a broadcast-capable client Seventh round on this block, and the last open defect from it. Hiding the raw esplora-client type stopped anyone naming it, but the facade still exported an unguarded connect() while the claim check sat in the node-side wrapper. Each earlier round had moved the type one level deeper and left the check where it was, which relocates a hole rather than closing it. The capability is now part of construction. The facade's connect() requires a witness value whose constructor is gated behind a feature only node enables, and ensure_legacy_publisher_allowed returns that witness after validating the claim. Possessing a broadcast-capable client therefore implies the check ran, enforced by the compiler rather than by convention, and a compile-fail test asserts a client cannot be built without one. One residual remains, reported rather than hidden: inside the node crate itself a caller could invoke the witness constructor directly instead of going through the claim check. Production paths do not, and closing it fully would mean merging the witness into the claim-check module at the cost of the package boundary that keeps raw esplora-client out of reach. The trade is worth stating before it is decided. Both known follow-ups are untouched: boot reconciliation still rejects every reorg of depth six or more while the live path differs, and a bitcoind tip below activation height is still treated as fatal. Full suite: 493 passed. * node: move the broadcast policy into a shared crate, drop the witness Final defect on this block. The witness closed the cross-crate hole but was public and feature-gated, so a caller inside node could construct it directly instead of going through the claim check -- possession no longer implied the check had run. Policy and construction are now co-located. A new zero-dependency stack-policy crate holds the process mode registry and ensure_legacy_publisher_allowed, and esplora-bound calls that check inside its own broadcast-client constructor. The witness type and its feature are gone. Every construction of a broadcast-capable client therefore runs the same check, from any crate including node itself, while raw esplora-client stays confined to esplora-bound. There is nothing left to forge and nothing to forget. The policy crate stayed small -- the process claim is plain mutex state, so no dependency cycle appeared. Two things surfaced about the test suite while verifying, neither related to this change. The shared postgres container had accumulated roughly 4140 leftover schemas and 485k relations from aborted runs, and the resulting catalog thrash cost minutes per test; recreating it fixed that. And api_remote is an end-to-end suite against a deployed node, which CI runs only in the deploy workflows and excludes elsewhere -- included by mistake it fails 49 times with HTTP 502. Excluding it is now part of the documented invocation. Suite: 506 passed, 0 failures outside api_remote. * node: make the process claim monotonic and unstall the test harness The claim was not monotonic in production: clear_process_stack_mode_for_test was public and compiled in, so a caller could withdraw a claim, obtain a broadcast-capable client under no claim, and re-set it -- leaving that client valid while components disagreed. The reset now exists only behind a test-support feature, and a compile-fail test asserts it is unreachable from a production build. The test harness stalled for anyone running the full suite: after 193 seconds a reviewer saw 6 tests passed, 18 hung and 482 not started. The shared postgres container had accumulated roughly 4140 schemas and 485k relations from aborted runs, and the attach-or-create path had no timeout. Container readiness now times out at 90s, pools are smaller, teardown is reliable, and failures say exactly which docker command fixes them instead of hanging. All 507 tests complete; zero leftover schemas afterwards. One test fails under load and passes alone in 1.5s -- scanner_ws watchdog timing. It predates this change and is being treated as a defect in its own right, not written off as noise. Wall-clock is 95.6 minutes under default parallelism. With the stall gone, the remaining cost is Plonky2-heavy tests rather than harness overhead. * scanner_ws: fix the watchdog race the flaky test was reporting The test passed alone and failed under load, which is usually written off as timing noise. Investigating instead of dismissing it found two defects, one in each place. The test raced a real timer against a wall-clock budget that does not hold when eight test processes share the machine. That alone would have been a test-only fix. But the watchdog was genuinely racy. A nested timeout in the ping arm blocks the select!, so the watchdog cannot be polled while that arm is blocked -- a full writer queue or a wedged flush is enough. At production values, ping every 30s against a 90s liveness bound, half-open detection can therefore be delayed well past the bound it is supposed to enforce. The flaky test was reporting a real liveness defect in the code it exercises. Both are fixed: the watchdog is polled concurrently rather than behind the ping arm, and the test asserts ordering instead of duration. Evidence: 24 consecutive runs under load, all green, 0.42-0.74s each. Raising a timeout would have hidden both. * node: make receive a real state transition under the v1.1 claim Legacy receive_coin_into proves nothing and publishes no nullifier -- it moves a coin into an account as bookkeeping. Under v1.1 a receive is state-advancing like any other transition: it produces a ComplianceProof, publishes an on-chain nullifier, and clause 10 binds every received coin to the proof that created it. Without that, a receive leaves no first-occurrence entry, so nothing on chain distinguishes it from a double-spend attempt. Behind the shadow flag the receive path now runs through the engine's transition flow and persists into the v1.1 tables. Clause 10 is enforced per active slot: the creating nullifier's sign-to-contract opening must verify and the consumed public key must match, and a receive cannot be constructed without them. MAX_RX_COINS is a hard gate rather than a silent truncation. With the flag off, receive_coin_into is untouched; the gate sits on receive_coin and only engages under a v1.1 claim. Deliberately out of scope, to be closed by G4: REST and job payloads, and the wallet-side sign-to-contract contract. Reorg-driven account unwind keeps the existing scan semantics. Tests exercise clause 10 in both failure directions, the MAX_RX_COINS boundary, and that the legacy gate stays open when the flag is off. They avoid a full circuit prove and apply the equivalent state effect test-side, so the proving path itself is covered elsewhere. * node: let the chain place the receive's nullifier, not the local process A review found three blocking defects, two of them the same mistake: local state treated as canonical before Bitcoin confirmed it. The receive called finalise before publishing, which appended its nullifier at a synthetic position. §3.6 defines the log as the fold of what the chain actually contains, ordered by (height, tx_index, vin_index, member_index) and folded by first occurrence, so an invented position is not part of it. The consequences were real: nullifiers mined earlier could sort after it locally, finality age started at the pre-broadcast tip, and the persisted NAV could diverge from an accumulator rebuilt from Bitcoin -- which later clause-10 checks would then consult. Publishing now leaves the log to the scanner, which folds the nullifier at its real chain position. Publish and persistence were not crash-consistent. The path mutated memory, broadcast, then persisted, and restored the old snapshot if persistence failed -- but a broadcast cannot be rolled back, and forward scanning rebuilds only the NfLog while deliberately preserving account rows, so nothing repaired the divergence. Intent is persisted before broadcasting, and the live state is never restored after a successful broadcast. The state-effect test blessed the first defect rather than catching it: it built an AccountRecord by hand with no proof and no NAV opening, then called only the publisher helper. It would have passed even if production proving rejected every receive. It is deleted and replaced by four tests -- an ignored full production-path receive through begin, prove, finalise, publish, persist and reload; multi-slot clause-10 corruption at slots 2 and 4 rather than only the first; a scan-reconciliation case where chain order contradicts publication order and the chain wins; and one asserting publish leaves the log to the scanner. Successor transitions can now only prove a predecessor after the scan fold; an absent lookup fails hard instead of consulting a synthetic position cache. Mint and send still finalise locally and carry the same defect. They are legacy paths today, so it is latent, but it must be closed before stage 3 wires the v1.1 prover. * engine: remove the synthetic local position entirely The deferral was a caller convention: the receive wrapper called the right function, but the public finalise accepted any pending transition and always chose a synthetic local position. The guarantee held only because today's caller happened to be correct -- and mint and send were not, which is why they still invented NfLog entries. The absent-lookup check could not catch that, because a synthetic entry is present rather than absent, and after a canonical replay relocated it the cached position disagreed with the chain permanently. SyntheticLocal, OwnNullifierCommit and stage_nflog_append are gone. If the chain has not placed a nullifier, no code path can act as though it has, so receive, mint and send are fixed together instead of three times over. The persisted intent now carries what a rebroadcast actually needs, in a new pending-publishes table, and the commit/reveal pair is recoverable rather than guessed at after a crash between the two broadcasts. Receive and scanner rollbacks are serialized behind a single write gate held across snapshot, mutation, persistence and restore, so one participant's rollback can no longer discard the other's committed work. The multi-slot clause-10 test now goes through the real entry point with only the target slot corrupted, and the error names which slot rejected. The production-path test could not be built as a genuine multi-hop Plonky2 run -- the creating proof must be circuit-valid and hollow shells fail at prove time -- so it is a documented status test rather than a panicking placeholder that looks like coverage. * engine: make chain position unforgeable, publishes recoverable, and prove outside the lock Five defects from the third review round. Appending was still a convention: public append_nullifier accepted an arbitrary ChainPosition, so nothing stopped a caller placing a nullifier where the chain never put it. This was the fourth time in this project that a guarantee rested on caller discipline, and the same remedy applies -- a position is now something only the scan path can construct from what it observed, so possession is the proof. The publish was not recoverable in practice. One crash window left an advanced account with no signature scalar and no way back; the resumer existed only as a manually callable function; and a rebroadcast treated 'already known' as an error rather than as the success signal it is. Intent is persisted before the account advances, a boot resumer picks up pending publishes, and rebroadcast is idempotent while still distinguishing done from failed. A schema test still asserted the 0020 table list and failed deterministically once 0021 added v11_pending_publishes. The end-to-end receive turned out to be slow rather than unbuildable, as the reviewer suspected. It now reuses the existing genuine mint fixture and a real Alice-to-Bob send, then Bob's begin_receive and finalise, asserting the credit, that finalise leaves the NfLog untouched, and that the position stays absent until the scanner appends it. Marked ignore for runtime. The write gate no longer spans the multi-minute prove, which had blocked the scanner for its duration. It covers snapshot, apply, persist and restore only. Ordering still holds because apply re-validates the pending envelope against the live engine -- previous account state and its own Pk still absent -- and fails loudly on collision rather than assuming the world stood still. * engine: prove without the engine lock, and decide success from this transition alone Proving was outside the write gate but still inside the engine mutex, so the scanner waited for every proof anyway -- the liveness fix was only half done. It now takes a consistent snapshot, releases both locks, proves, and re-acquires for the state-critical section. The re-validation on re-acquire was incomplete, and rather than adding the four fields the review named, the list is derived from what the code actually reads between snapshot and commit. Extending a list by hand closes this round; deriving it closes the next one too. Two races followed from the gap. A stale global size comparison could be decided against a size_final a concurrent scanner had already moved; pre-apply NfLog size is now measured inside the write gate, so 'apply must not mutate the NfLog' is a local invariant of this apply rather than a claim about a global anyone can change. And after a successful broadcast an unrelated append made success and failure indistinguishable; the outcome is now decided from what this transition did. The end-to-end test reaches through verify_and_begin_receive, apply and re-validation, atomic persistence, publisher construction and boot reload, with a real Plonky2 prove in the ignored variant. It stops at live bitcoind, chain inclusion and the scanner fold of its own nullifier -- stated as a table rather than implied, because a test's boundary is worth knowing precisely. * engine: revalidate everything the commit depends on, not only what it reads The previous derivation asked what the code reads from the engine between snapshot and commit. That is the right question with a blind spot: values handed in from outside are never read from the engine, so they never appear in the list. build_tip escaped exactly that way -- caller-supplied, copied into the member, durably committed, never checked against the snapshot's tip identity. The method now covers everything the durable commit depends on, whichever direction it came from. Applying it found a second escapee the review had not named: the commit signature, which lands in the member as s and r_prime and is now required to be byte-equal to the proved envelope's. The outcome fields also described the world rather than the transition: admitted_coin_ids was populated from all currently spendable coins and new_send_counter re-read from live account state after the gate was released. Both now come from the proved witness, so they say what this transition did. The boundary table is corrected too. It was accurate only if 'publisher construct/broadcast' is read as the fake RecordingPublisher; the default suite establishes neither proof validity nor real publisher construction, and now says so. An over-generous boundary claim is the same defect as an over-generous test. 17 tests pass. * engine: make the proved envelope a capability, not an argument The fifth instance of the same pattern in this project. commit_proved_receive was public and accepted a caller-supplied proved envelope, so the third caller-supplied durable value was the purported proof itself -- and the production-path test demonstrated reachability by constructing a hollow proof and succeeding. Everything downstream assumed that envelope came from an actual prove; nothing enforced it. The envelope is now constructible only by the code that proves. from_parts is private, the test constructor exists only behind a feature, and a compile-fail test asserts a production build cannot fabricate one. commit_proved_receive keeps its signature and is safe because its argument cannot be forged. Capability rather than verify-on-commit: re-verifying a Plonky2 proof on a path that holds the write gate costs real time, while possession of the type costs nothing at runtime. The same question was asked of every other public entry point in the module, and a focused test now proves an altered s or r_prime is rejected with no durable write. 19 tests pass. The five instances, for the record: the broadcast client, the stack marker, the signature provenance, the chain position, and now the proved envelope. Each time a guarantee rested on the caller doing the right thing; each time putting the capability in the type was the fix. * engine: close the test seam at cfg(test), and remove the last proof bypass A Cargo feature is not a boundary. from_parts_for_test sat behind an ordinary feature, so anyone could build with --features zkcoins-prover/test-utils and any dependency could enable it transitively; resolver v2 only stops the current dev-dependency from leaking. The guarantee was again conditional on nobody doing the wrong thing -- the fifth time that has failed here. The hollow constructor now exists only as cfg(test) inside the defining crate, where no external build can reach it. Tests in other targets obtain a proved envelope the way production does. publish_applied_nullifier was a second bypass the previous sweep missed: public, re-exported, and accepting a fabricatable applied transition. It is closed, and the sweep was redone as a table listing every public entry point that writes durable state or publishes, with the guarantee that makes each one's arguments unforgeable. 16 tests pass. * engine: seal the plumbing instead of patching helpers one at a time Five rounds each closed one leak, and a sixth found another. The reviewer named the reason: public raw plumbing was being treated as though call-site convention were a capability boundary. Patching helpers cannot fix a shape that admits arbitrarily many of them. The sinks are sealed. Database writes, adapter mutation (with_engine_mut, restore_live, set_tip_hash, persist, reload_from_db, lock_writes, snapshot_live) and scan-apply are private; what stays public is the orchestration that already carries its capability. A caller can no longer assemble a durable effect out of raw parts, because the parts are not reachable. One downstream compile-fail matrix states the whole boundary from outside the crate, across profiles, dependency edges and feature combinations, rather than five scattered tests each covering whatever was on someone's mind that round. Closing the test seam had cost coverage: concurrency and end-to-end tests went with the hollow fixture. They are rebuilt on the sealed API using the real proving path, ignored where slow -- including one asserting a concurrent scanner append during proving still commits correctly. dev and release both build; 16 receive tests and 49 v11 tests pass. * engine: wrap the foreign publisher, and prove reachability rather than naming The sealing round closed our own wrappers and then handed out the thing they wrapped: connect_v11_publisher returned the raw foreign Publisher, whose inherent prepare, broadcast_commit, broadcast_reveal and publish stayed callable. A downstream probe depending only on node compiled all four, and a second reached them by trait method with free-standing batch members. The matrix had missed it because it probed the private wrapper names. That proved the names were private, not that the capability was unreachable -- the same defect as a test that checks its own logic rather than the code's. The foreign type no longer leaves the module. An opaque V11Publisher facade carries only what callers legitimately need, and test substitution uses private polymorphism inside the crate instead of exposing the real type. The matrix now proves reachability from a downstream crate: inherent calls fail with E0599 on the facade, the remaining methods with E0624, the UFCS routes with E0433 and E0603, argument construction with E0422, and the direct crate path with E0433. The weaker unrelated-coin outcome coverage stays documented as a gap rather than papered over. 16 tests pass; dev and release build. * engine: make the boundary matrix fail when the boundary moves The facade was sound but its proof was not. The probe hardcoded the facade type instead of deriving it from the connect expression, so changing connect back to returning the raw publisher would have left the matrix green -- it pinned a name, not a boundary, which is exactly why it survived while the foreign type was being handed out. The trybuild fixture also depended on zkcoins-prover directly, so it was never a genuine downstream probe. The probe now takes its type from the connect expression, the fixture depends on node alone, and explicit coercion, Deref, AsRef and public-API-pin cases guard the routes a future widening would use. Demonstrated rather than asserted: with connect temporarily returning the raw publisher the matrix fails, and passes again after reverting. A boundary test nobody has seen fail is a claim, not a guarantee. 16 receive tests pass. * node: verify the v1.1 transition signature against the spec's own fixture The two signing protocols bind different things. Legacy signs a commitment over ash and ocr; v1.1 signs BIP-340 with a sign-to-contract tweak over the full canonical serialize(ProofData) and the per-network m_state. A signature from one says nothing about the other, which is why the node cutover cannot happen without wallet parity. Behind the shadow flag the node now verifies both halves and rejects unless both pass: BIP-340 over the per-network message, and the S2C opening R = R' + H(bytes(R') ‖ H(ProofData))·G. Accepting 'the BIP-340 part verified' as sufficient would leave the signature unbound to this particular proof. A signature carrying another network's m_state is rejected outright, which is what the per-network message exists to prevent. The conformance test is the point of the block: it verifies V.5's pinned signatures for mainnet, testnet and regtest -- the values regenerated yesterday and now in the specification. A node that cannot verify the spec's own fixture does not implement §3.2. The negative tests each assert which check rejected: wrong network, a valid BIP-340 signature whose S2C opening does not match, and a signature bound to different ProofData. With the flag off the legacy commitment path is untouched. Three plan corrections worth recording. R' is not part of the 96-byte SpendRecord -- the on-chain pair is (Pk, R) and the wallet must send the S2C nonce separately. The host primitives already existed (half_agg::verify_single, comm_verify, serialize_proof_data), so this wires them with fail-closed checks rather than reimplementing cryptography. And the REST /sign route stays unwired until stage 3; this block provides the verification API that receive and send call. * node: derive the signed payload from the transition, and wire the check in A review found the cryptography correct but the binding decorative at the node boundary. accept_wallet_transition_signature took expected_pk_i and proof_data as independent parameters, so a caller could verify a signature against one payload while the transition it authorises carried another. The check then proved the signature matched the bytes the caller passed, not the transition being finalised. It now takes the PendingTransition itself as the sole source of both, so a mismatched pair cannot be constructed. The block was also not wired in: the new functions were referenced only by tests while the live job flow still surfaced legacy ash/ocr. Under a v1.1 claim the transition path now verifies the v1.1 signature and refuses a legacy commitment, in both flow.rs and the jobs route. With the flag off nothing changes. The REST /sign route remains stage 3. Two smaller corrections. My earlier commit claimed the V.5 values are 'now in the specification' -- they are not: spec-v1.2 still shows there because our vectors PR is an unmerged draft. The comments now state the pins come from the reference implementation's generated fixture, proposed for V.5 in PR #124. Provenance matters here, because this fixture is what a second implementer will trust. And the documented wire contract disagreed with the parser. It is now exact: signature is bare lowercase hex of bytes(R) || bytes(s), 128 characters; s2c_nonce is bare lowercase hex of the x-only even-y R', 64 characters. A 0x prefix, uppercase, whitespace or a wrong length is rejected loudly rather than silently normalised. * node: give the v1.1 signature a route, and make jobs advertise what to sign The verification logic had no caller and no wire boundary, which was my scoping error: I excluded the REST route as 'stage 3', but stage 3 is the atomic switch -- an additional flag-gated endpoint beside the legacy one is additive and belongs here. Under a v1.1 claim there is now a submission route that decodes the documented contract and verifies before finalising. The encoding is enforced at the boundary rather than described in a comment: lowercase hex only, exactly 128 characters for the signature and 64 for the s2c nonce, no 0x prefix, no whitespace, no silent case folding. Failures are distinguishable -- encoding faults return 400 with 'encoding', a failed S2C opening 409 'stale_message', a failed BIP-340 or key check 409 'invalid_signature', flag-off or wrong phase 409 'wrong_phase'. Jobs also advertised the wrong thing. Mint and send published legacy ash/ocr unconditionally in awaiting_signature, so a v1.1 wallet reading them would sign fields this node then rejects -- a contract mismatch, not cosmetics. Under a v1.1 claim a job now advertises the six ProofData digests, the proof data hash, the transaction public key and the send counter, which is what a v1.1 wallet needs to recompute H(ProofData) and sign the per-network m_state with the sign-to-contract tweak. With the flag off the legacy pair is unchanged. The fixture generator's wording is corrected too: the values are the reference implementation's output, proposed for V.5 in PR #124, which is an unmerged draft. No generated value changed. * node: follow §7.5 literally and carry an accepted signature into finalise The previous round invented a shape where the specification defines one. The route was /api/jobs/:id/sign instead of /v1/jobs//sign, 'encoding' was an invented outward error where §7.5 defines a closed enumeration, the fields sat under result instead of awaiting_signature, and progress was an integer 0-100 rather than a float in [0,1]. All four now follow the section as written; the legacy /api surface is untouched beside it. An accepted signature also went nowhere. pending_sign_map was never populated outside tests, and the dispatcher marked the job completed with the signature material instead of driving finalise. A job entering awaiting_signature now stages its pending transition, and an accepted signature carries it through. send_counter was a free field the caller could set independently of the transition it describes -- the same decorative binding this project keeps producing. It is derived from prev_account_state. Staging was also lost on restart: boot resumed awaiting_signature jobs but could not reconstruct their pending transition, so /sign failed afterwards. The staged entry is persisted on the job row and rehydrated on resume. * node: couple acceptance to processing, and let §7.5 own the error surface /sign reported 200 signature_accepted even when no dispatcher would process the signature. Reporting success for work that will not happen is worse than failing, because the wallet believes it is done. Acceptance now requires a parked notifier that has been woken after the verified signature is durably persisted; without one the caller sees a failure rather than a false success. Restart rehydration could finalise from a partial reconstruction. What finalise requires is now established explicitly, and a rehydrated transition that cannot prove it has all of it is refused rather than finalised. Stale envelopes are cleaned when a job leaves the sign phase instead of accumulating. The error surface belonged to the framework rather than the specification: Axum extractors rejected malformed UUIDs and bad JSON before the handler could shape them, so clients saw framework errors instead of §7.5's enumeration. Dedicated V1JobId and V1Json extractors now map those rejections into 400 malformed_request first. wrong_phase is used only where §7.5 defines it, the invented dispatcher status is gone, and stored failures are no longer all labelled proving_failed. The success result carries output_coin_ids and publisher_pubkey, which §7.5 defines and which were empty and absent. * node: stage from the dispatcher, and close the handoff race Three rounds tried to wire this block and each left the same hole: nothing in production staged a live pending transition, so the route verified against staging that only tests created. That was my scoping error -- the other half of the lifecycle lives in the dispatcher, which I had kept out of the block. It is in now, and a job entering awaiting_signature stages its transition where it actually exists. Acceptance also raced the dispatcher. The handler cloned the notifier, so the dispatcher could time out or vanish between the clone and the wake while the caller was told the signature was accepted. Acceptance is now decided against a handoff that is still live when the wake happens; a timed-out dispatcher yields rejection. Cleanup runs on every exit path rather than the happy one: timeout, missing job after signalling, invalid commit body, v1.1 finalise success or failure, and failed staging. Three smaller conformance gaps closed: stored error strings are validated against §7.5's enumeration instead of trusted, a malformed publisher_pubkey fails rather than silently vanishing, and the flag-off timeout error is byte-identical to before -- the structured form stays on the v1.1 path only. * node: use the sealed accessor after rebasing onto the receive merge The rebase onto G3 surfaced two direct reads of AppliedTransition.proved, which the sealing made private. That is the boundary doing its job: the orchestrated accessor exists and the compiler pointed at it. * node: stage the real pending transition, and persist before signalling Now that the branch is rebased onto the merged receive work, begin_* produces a self-contained PendingTransition that can actually be staged. The dispatcher takes it once after the begin leg and stages it for the signature route, so /sign verifies against production staging rather than something only tests create. Staging holds the full pending rather than an engine snapshot, so it fits the prove-outside-the-lock shape the receive path established instead of reintroducing state a concurrent scan could move. The handoff ordering was inverted: the state went to SIGNALED before the signature was persisted, so a crash in between left a job marked signalled with nothing durable behind it. The order is now persist, then compare-and-swap, then notify, and each crash window leaves something recoverable -- no signature and a waiting handoff, a durable signature and a waiting handoff, or a durable signature with the handoff re-armed on boot. Cleanup runs when set_awaiting_signature fails, instead of leaving the map, envelope and notifier behind. /stream now emits event: error with an enumeration code for failed and cancelled jobs rather than event: complete with a raw string, and /cancel implements §7.5's actual condition -- not yet published -- so proving and awaiting-signature jobs can be cancelled while a published nullifier cannot. * node: confine the cancel widening to v1.1, and make a crashed sign resumable Widening /cancel to §7.5's not-yet-published condition had widened JobStore::cancel itself -- the shared store -- so legacy cancellation changed too. Every block in this cutover is additive: with the flag off, behaviour is byte-identical. The legacy store accepts only queued again, and the v1.1 handler uses its own method. Persisting before signalling was only half the point: the durable bytes existed but nothing drove the job to completion afterwards. wait_for_commit now checks for a durable signature before parking, so a job crashed after persist, CAS or notify is resumed on boot without a second /sign. Cleanup was best-effort cleaning up after a best-effort write. It now clears the in-memory map only, with rehydration bound to awaiting_signature, so a failed or cancelled job's envelope cannot resurrect it. The v11_pending_after_prove test injection point is behind cfg(test); production uses only the live registry. * engine: one durable finalisation capability instead of reassembled state Seven rounds of patching the persistence shape each closed one crash window and left another, because the state needed to finish a transition lived in several places and a restart had to reassemble it. The reviewer's verdict was the same one that unblocked the receive path: change the cut, not the patch. FinalisationCapability is engine-owned and durable, and carries everything finalisation depends on -- derived the way the receive path derived its re-validation list, from what the operation actually needs including caller-supplied values, rather than from what was convenient to store. Resuming is now reading one record and proceeding. Resume is idempotent by construction: status-qualified updates fail rather than apply when the job has moved on, so running it twice cannot double-publish, double-credit or disturb a terminal job. The recovery tests were invalid -- they exercised a warm process pretending to be cold, which is why they passed while resume was incomplete. The new test drives a persisted job to completion from database bytes alone, with no in-memory carry-over, which is what a restarted node actually is. Legacy is untouched with the flag off: cancel stays queued-only, the unqualified complete/fail/set_status paths are unchanged, and the new compare-and-swap methods exist only on the v1.1 path. coinhist gains Serialize/Deserialize so the capability persists as one blob; no derivation, formula or hash changed, and the generated vectors are unmoved. * engine: carry the capability to completion, and claim the job exclusively Three things finished the capability approach. The capability stopped at prove and apply, so publication and job completion had no durable dependencies and a job could still reach a state resume could not finish. It now covers the whole path through to completion. broadcasting was permission rather than ownership: two resumers reading awaiting_signature could both proceed, and a second broadcast is not made harmless by the first having happened. Acquiring the job is now a compare-and-swap that exactly one resumer wins; the loser exits immediately with what it observed instead of continuing because the status looked inviting. A dead process's claim is released at boot before the job is re-enqueued. The cold test was warm: it cleared maps but reused the same AppState, drove the dispatcher by hand and injected a hook, so a capability missing a field would still have passed. The property that matters is now asserted directly -- an incomplete capability fails resume rather than half-finishing quietly. Ten tests cover the exclusive claim, concurrent resumers, a harmless second resume, and refusal on an incomplete capability. * engine: name the host edge, lease the claim, and let the loser leave quietly Three rounds each found completion ending earlier than claimed. It ends at the host edge -- proving and the in-memory engine -- because chain inscription needs a live bitcoind and the V11Publisher, which this path does not wire. That is a design boundary of the job finalise hook, not a test limitation, and it is now named as JOB_FINALISE_HOST_EDGE in the code rather than left to be discovered. Everything up to that edge is durable, so resume drives a job to exactly the point where the chain would take over. The claim had no owner. release_stale_finalise_claim checked status and phase only, so a running process's claim could be freed and its job handed to a second resumer -- reintroducing the double execution the claim exists to prevent. A claim now carries an owner and a lease that the live owner renews; release requires the lease to have expired or never to have existed. Stale means demonstrably abandoned, not merely old. And the losing resumer no longer removes the notification state, which by then belongs to the winner. It observes that it lost and returns. Tests cover a live owner surviving a boot sweep, a loser leaving the winner's state intact, and resume reaching the documented edge rather than stopping silently. * engine: make the host edge durable and keep the lease alive through the prove Naming the edge was right; leaving nothing behind it was not. The hook mutated only the in-memory engine, so a job reaching the edge left nothing for the publisher work to pick up and a crash there lost it. The applied state is now persisted and the pending publish staged, so a restarted node finds a job sitting exactly at the edge with the bitcoind broadcast still outside it. The lease was renewed once, immediately before a prove that can take minutes, so it expired while its owner was alive and working -- a boot sweep then freed it and a second resumer started the same job, which is the double execution the claim exists to prevent. A heartbeat now renews every five minutes for the duration of the prove: liveness is demonstrated continuously rather than asserted once. And there were two clocks. Expiry was written with the application's Utc::now() and evaluated with PostgreSQL's NOW(), so any host/database skew silently shortened or lengthened every lease. Both sides now use NOW(), which is where the comparison happens. 15 tests pass, including a crash at the edge being picked up by resume, a prove outlasting the lease period without admitting a second resumer, and completion driven from durable capability alone in a fresh AppState. * engine: lose the lease, stop the work; and never enqueue a job still owned The heartbeat failed open. A renewal returning false, a database error, or the heartbeat task dying were logged and the prove carried on, so the lease could lapse while the worker kept going, another resumer could claim the job, and both would apply -- the split-brain the claim exists to prevent. Losing the lease is not a warning; it is the loss of the right to proceed. All three signals now abort the work and discard its result, including the task disappearing, which was the quietest of the three. Boot could also strand a job at the edge. It attempted a stale release, ignored a false result, and enqueued anyway, so an immediate restart -- the common case -- could hand out a job that was still owned. The release outcome is now honoured, with each combination of outcome and prior phase resolving to a defined state: still owned means not enqueued, genuinely free means enqueued, and a database error means the row is left alone rather than guessed at. Tests cover all three heartbeat failures aborting mid-prove, a lease lost through the real store, an edge job enqueued when the phase is genuinely free, the database clock being authoritative, and clock skew not expiring a live lease. * engine: fence the durable writes on ownership, not on cancellation Dropping a future is a request, not a guarantee: in Rust it takes effect at the next await point, so a worker that lost its lease could keep running for as long as it liked. Fail-closed cannot rest on cooperative cancellation. The fence now sits on claim ownership in the durable writes themselves. Every write that completes a transition is conditional on this owner still holding the claim, so a worker that lost its lease commits nothing however late it notices. Status alone was never sufficient -- after a reclaim, a different owner is legitimately in broadcasting too, so the status says what is happening and not who may do it. The renewal wait is bounded, so a stalled renew counts as a liveness loss rather than a pause. A database error at boot now leaves the row entirely untouched for retry instead of being half-handled. And reclaim no longer gives up: the fixed fifteen-minute deadline is gone, the deferred path polls until the job is free, terminal or no longer broadcasting, and the next boot re-lists interrupted jobs and schedules reclaim again. A deadline that discards work is a silent loss. Tests: all three heartbeat failures, a stalled renewal treated as loss, a lease-less worker unable to commit, a database error leaving the row untouched, a prove outlasting the lease, and deferred reclaim after expiry. * engine: fence durable writes with a per-claim token, not an owner identity Owner identity cannot fence a write. The same process can hold an old claim and a new one -- after its lease lapsed and it reclaimed -- and an owner-qualified write cannot tell them apart, which is why a worker that lost its lease could still commit engine state and members_ready. The previous test only covered reclaim by a different owner, so it missed exactly the cases that matter. Every acquisition now draws a fresh monotonic fence from a sequence. Durable writes are conditional on the fence current when the work began, so a stale token loses even when the owner matches: what changed is not the owner but the epoch. Renewal preserves owner and fence and only extends the lease, so a stale fence cannot renew a new epoch either. A write also revalidates the lease, so a current token with an expired lease commits nothing. One terminal write still reached an owned row through a status check rather than the token -- the pre-claim failure helper permitting Broadcasting. Every write that can terminate or complete a job now carries the fence, found by sweeping for the shape rather than fixing the one instance. Migration 0022 adds the sequence. Tests cover a same-owner reclaim rejecting the old epoch, a current fence with an expired lease, the pre-claim path unable to terminate an owned row, and a lease-less worker unable to commit. * engine: fence the hook's commit, and account for every job-advancing write The fence stopped at the boundary of the write that matters most: the production hook received only the pending transition and the signature, so the commit writing the engine snapshot and staging members_ready could not check it. The fence is threaded through and that commit is now conditional on fence, owner and lease like the job-row writes. The sweep had also missed the awaiting-signature timeout, which terminated jobs unfenced. That is the second sweep in this project to report completeness and miss an entry, so it is now a table rather than an assurance: every write that advances or terminates a job, with the fence it carries, and an explicit list of what stays unfenced by design -- the pre-claim phase moves and legacy prove failures, where no exclusive claim exists yet. fail_if_status and complete_if_status remain status-only but can no longer touch a claimed row; the bare legacy fail and complete are no longer reachable once a claim can exist. * engine: derive the fence table from the SQL, and close two writes it exposed The previous table was composed from memory and said set_status was a status CAS. Its SQL is WHERE public_id = -- no status predicate at all -- and four writes were missing entirely. A table describing what one believes one wrote is the same class of evidence as a test that checks its own logic. It is now derived mechanically: every mutating statement located in the source, each row quoting its actual WHERE clause, with the fence read off that clause. The table records what the code does, including where that is weaker than the name suggests. Two P0s the derivation exposed. Boot resume decided from a previously loaded snapshot and then called bare fail without rechecking status, so a job claimed between the listing and the write could be failed by the sweep -- which also falsified the earlier claim that legacy prove failures are unreachable once a claim exists. And after set_awaiting_signature another process could sign and claim before the originating worker's confirmation load, sending that worker into a cleanup branch that wrote over a claimed row. Both writes now refuse a row in the handoff or claimed phase. Tests cover boot resume unable to fail a job claimed since its snapshot, and the cleanup rewrite unable to touch a claimed row. * engine: derive nav_rand from op_secret, and stop accepting it from the caller * engine: redact the operational secret, and restore a real node to prove it * engine: make the operational secret unreachable, not merely unprinted * node: self-heal and canary for the v1.1 circuit Self-heal existed for the legacy stack only. circuit_digest_bytes lived on the legacy Prover, so the boot-time comparison had nothing to check against on the v1.1 path, and the canary rebuilt a CMP from the global SMT and MMR -- neither of which exists under v1.1, where a canary needs the predecessor nullifier, the NAV and the previous ComplianceProof instead. Behind the flag, boot compares the live digest of C against its pinned constant and drives the reset path on a mismatch rather than logging it. A full canary proof is too slow for boot, so that boundary is explicit: the fast check runs at startup, and an operator triggers the deep check with ZKCOINS_V11_SLOW_CANARY=1, which verifies a persisted proof through the bridge and resets on staleness. Legacy self-heal is untouched and byte-identical with the flag off. 114 tests pass. * node: derive the canary digest from the circuit this binary contains * node: check the digest of the circuit this binary builds, and fence resets by generation * node: serialise reset against admission, and make a zero-row write say so * engine: lock the generation read on every advancing write * node: let a normal run catch a digest shortcut * node: produce a §5.7 balance attestation behind the shadow flag ProverBridge::prove_attestation existed with no route or job path to reach it, so the node could not produce an attestation at all. Behind the flag there is now a job path and a §7.5 route. The section is normative for the surface, so route, field names, error enumeration and types follow it rather than a plausible shape -- the previous block lost a round to an invented route and an invented error code. C_balance is network-dependent and its digest is a pinned constant per network, so an attestation verifies against the digest for the network this node runs on and is rejected for another's. The edge is named rather than papered over: where the attestation cannot be completed here the job fails with an edge message instead of fabricating a zero result. Two gaps in §7.5 are reported rather than filled by invention, the first being Bitcoin locator persistence, which the section does not specify. 93 tests pass. * node: bind the digest tests to the production gate, and reuse the merged extractors The digest tests compared constants and simulated an inequality without ever calling the acceptance gate, so removing that gate would have left them green -- the defect class this project keeps hitting. They now exercise the real gate, demonstrated rather than asserted: weakening it to always succeed turned attest_c_balance_digest_gate_is_production_bound red, and restoring it turned three tests green again. A binding test nobody has seen fail is a claim. Canonical serialization, a completed anchor, a terminal success and the named locator-edge error had no tests at all; they do now. On the surface, §7.5 owns the types: expiry and size_ceiling follow the section rather than convenient JSON shapes, and the root endpoint map advertises both attestation endpoints. Malformed input goes through the V1Json extractor already merged from the signature block instead of a third variant of the same fix -- parallel lanes do not share solutions automatically, which is why this recurred after being solved once. 99 tests pass. * node: canonical proof bytes for the balance attestation, and real anchor coverage * node: resolve the attestation anchor at any depth, and keep the flag-off surface identical * node: serialise the root response in declaration order, and freeze it as bytes * engine: re-mint into an existing asset account * engine: obtain the shadow capability from the process, not from the caller * engine: establish provenance through CoinHist, and seal the legacy witness out * node: gate the stack reset in its defining crate, not behind a feature * probe: measure the v1.1 prover on its own budgets, and refuse when they are unsealed * node: reconcile the six merged blocks without weakening the stack seal * node: name the stack after the protocol version it implements * node: switch the binary to v1 and cut the legacy prover off the boot path * node: make the legacy path unreachable by inverting the public surface Stage 3 closes the legacy prover path. Five earlier rounds sealed named entry points and each round found another one, because the boundary was maintained as an enumeration: node carried the broad public surface of an application while spec v1.2 §7.5 makes it a kernel. The default is now crate-private. node's public surface is an explicit positive list documented at the top of lib.rs, one reason per entry; everything else is pub(crate) or private. import_account, persist_account and a mutable state() are deliberately not on it, and the legacy SQL sinks are gated at the sink rather than at their callers. The legacy prover, its free builders and the legacy commitment scan are deleted rather than sealed - a seal is a guarantee that has to be maintained, and maintenance failed twice. Endpoints that returned legacy account state without a capability now answer 410 Gone: receive, balance, balance/:address, proof/:id, history, history/:id, address, inscriptions/:txid. The hex-prefix fallback in username resolution is removed; it told any caller whether a legacy account existed. Verified: workspace check clean with and without --all-features, 10 compile-fail cases, downstream-boundary green, 381 node tests green. A downstream probe that installed and mutated legacy state no longer compiles. * node: delete the legacy proof path and pin the toolchain Stage 4 removes what Stage 3 made unreachable. The legacy circuit body, its witness helpers and the recursion scaffolding are gone: circuit/main.rs drops from 4329 lines to 58. Helpers whose only callers were the endpoints that now answer 410 Gone go with them, and test-only fixtures move under cfg(test). What survives is the v1 engine. Items the gRPC layer will consume stay public with an individual reason on the positive list, so they are API rather than dead code, and the surface coverage test pins them to the allowlist. Six durable write paths keep an explicit too_many_arguments allowance, each with a one-line reason: regrouping lease, fence and tip arguments into a struct would reshuffle a crash-window-sensitive call surface without making anything safer. rust-toolchain pinned to nightly-2026-07-07. The channel was plain 'nightly' while CI runs clippy with -D warnings, so a new nightly adding a lint turned CI red without anyone touching the code - manual_is_multiple_of did exactly that, on this branch and on the base. Verified: three clippy gates clean, workspace check clean, 8 compile-fail and surface cases, downstream-boundary, 351 node tests. * chore(toolchain): pin nightly to 2026-06-18 (unpinned channel broke CI: stricter rustfmt + new chunks_exact lint on 1.99.0-nightly) * docs(docker): describe toolchain pin as dated nightly (comment drifted with the pin) * fix(mint): derive account owner as SHA-256 address per spec (#226) The multi-asset mint credited the creator account under owner = Poseidon(creator_pubkey), but the spec defines the address/owner as H(Pk0) = SHA-256(pubkey) — what the SDK, username-claim, SMT and receive path all use. Minted balances were invisible/unspendable to spec-conformant wallets. - digest_from_bytes: from_canonical_u64 -> from_noncanonical_u64 (align with its doc; an externally-supplied 32-byte SHA-256 chunk can exceed the Goldilocks modulus); add sha256_to_digest helper - off-circuit owner -> SHA-256: AccountState::new, prepare_mint, validate_mint_request - circuit: drop the in-circuit owner == Poseidon(creator) binding; forge protection retained by asset_id == Poseidon(creator) AND public_key == creator (plus the off-circuit creator signature) - tests: owner asserts -> SHA-256; owner-negative gate test reframed onto the pubkey binding; test wallet address helper -> SHA-256 Hard fork: changes the verifier key -> existing proofs/state become invalid (DEV needs reset_state on deploy). * test(mint): pin Variant-B owner relaxation + harden hash tests; fix stale docs (#226) Review follow-up (no behaviour change): - circuit test mint_accepted_with_arbitrary_owner: a valid mint with owner != SHA-256(creator) still verifies (owner is not gated), pinning the removed owner==Poseidon(creator) binding against silent regression - hash tests: sha256_to_digest known-vector + non-canonical digest byte round-trip (documents the from_noncanonical_u64 + raw-limb contract) - docs: correct stale comments still claiming the in-circuit owner==H(creator) binding (prepare_mint, MintWitness, mint_account, asset_id-negative test, digest_from_bytes) * docs(hash): describe digest_from_bytes as raw (no reduction); warn against canonicalising digest_to_bytes * test(mint): disambiguate arbitrary-owner comment ('non-canonical' collides with field-element terminology) * chore(fmt): apply cargo fmt (branch was never fmt-checked while in draft) * test(api_remote): align E2E suite with multi-asset contract - thread required asset_id through /api/balance and /api/jobs/send (+ helpers) - drive the two-phase creator-signed mint (admit -> awaiting_signature -> commit) - repurpose obsolete mint negatives to Model-2 (bad-sig / stale-ts -> 401) - move per-field hex/length error-string provocations onto the send path - remove the obsolete MINTING_ADDRESS scaffold - ignore the mint->balance/send roundtrips pending the node owner-hash fix (#226) * test(api_remote): split error_strings; add asset_id-missing 422 test (#226) Review follow-up: - split error_strings_match_known_app_mapping: the mint-INDEPENDENT lockstep strings + length guard run again (un-ignored); the mint-dependent "Insufficient funds" provocation moves to a separate error_strings_insufficient_funds (#[ignore] pending #226) - fix the send length-error assertion surfaced by un-ignoring: the send path emits the combined "address must be 32 bytes (64 hex chars)", not a per-field message - add balance_address_without_asset_id_returns_422 for the per-(owner, asset_id) 422 contract * test(api_remote): thread asset_id through send error-envelope test so it exercises the unknown-account path (#226) * chore(fmt): apply cargo fmt (branch was never fmt-checked while in draft) * style: apply rustfmt across the workspace CI runs `cargo fmt --all --check` (ci.yaml:139) but never executed on this branch, so 339 diffs had already accumulated before the cutover and the cutover itself added the rest. Purely mechanical: every file in this commit is byte-identical to `cargo fmt --all` applied to the parent commit. * test: align expectations and trybuild output with the post-cutover tree - send_coins assertions now pin the loud Stage-3 refusal instead of the pre-cutover "Unknown account" / "Insufficient funds" arms, which are unreachable now that the legacy prove path is gone. - trybuild .stderr files re-blessed: the compile-fail cases still fail, but the diagnostics changed with the narrowed visibility. - openapi_smoke, r2_budgets and self_heal expectations follow the closed routes and the v1-only write path. - program-plonky2: drop an allow for a lint the pinned nightly does not know. Known open item, tracked in this PR: 18 legacy-path tests in account_node_tests.rs are marked #[ignore] and are NOT accepted as-is — they cover prepare_mint/receive_coin against the deleted prover and are being reworked in this branch. * test: retire the legacy-path tests onto the v1 entry points Eighteen tests in account_node_tests.rs drove prepare_mint / receive_coin / send_coins against the prover the cutover deleted. They had been marked #[ignore], which is not a fix: an ignored test cannot fail, and it reports "skipped" rather than "failed", so the suite looks healthy while the properties go unwatched. Seven are ported onto the v1 entry points and are live again — single-output mint, amount-1 mint, receive crediting a balance, the already-admitted replay branch, tampered output inclusion, and the send-side input/output bounds. One is dropped against a named v1 test that already pins the property (provenance.rs, AccountUpdateProof mode after a prior transition). The remaining ten covered properties that the legacy transition model owned and v1 no longer has in that shape: a caller-supplied prev_commitment_pubkey, the global commitment index, the coin queue, the history MMR, and the single-asset-per-transition rule that per-asset conservation replaces. Deleting them is deliberate, but the properties they stood for are picked up by the guard tests in the following commit — not dropped. * test: make the begin_send / begin_mint / begin_receive guards fail The previous commit removed legacy tests whose properties still hold in v1 — they moved into guards on the v1 entry points in state_engine.rs. Those guards had no tests: the strings "not spendable", "not Admitted in coinhist", "recipient is not the spending", "duplicate input coin_id" and "account not found" each occurred exactly once in the file, which was the guard itself. A guard no test trips is indistinguishable from a missing one. Adds 31 tests that trip them, asserting on the error cause rather than on is_err() so a test cannot pass for an unrelated failure. Notably the multi-asset over-spend case: begin_send_overspend_returns_err was single-asset, so per-asset conservation — the property the deleted "foreign asset in the queue" test stood for — was unverified. Two guards remain untested and are being covered separately: the coinhist admission check, and the prior-account-transition requirement. * test: make the vector gates able to fail, and add the §4.3 name-consent framing Three of the four normative test-vector generators wrote their output file unconditionally and then read back what they had just written, so a drift in a domain tag or in the Hc encoding could not fail them. One of the two `shared` files was additionally gitignored, so there was nothing to compare against at all — while its values are pinned in the public specification's V.4 table. - generated_poseidon_vectors.txt is now tracked (.gitignore entry removed). - The poseidon, nflog and sig-agg generators verify against the committed file by default and only rewrite it under REGEN_POSEIDON_VECTORS=1 / REGEN_NFLOG_VECTORS=1 / REGEN_SIG_AGG_VECTORS=1, mirroring the circuit-digest test that already had it right. The drift message names the likely cause and the regeneration command. - shared::spec_v1 gains the §4.3 / V.12 name-consent framing: normalize_name, name_consent_preimage and name_message, with the mutation tests the specification requires individually (different network, u32 little-endian, name_len off by one either way, foreign op_pubkey) plus the un-normalized control that must produce an identical digest. The V.12 fixture is emitted into the vectors file so the value the specification pins comes from the reference implementation rather than from a hand computation. * fix: enforce the §4.3 identifier grammar before framing a name consent name_consent_preimage normalized its input but validated nothing beyond rejecting the empty string, so any byte sequence could be framed into a value the seed holder then signs. normalize_name is to_ascii_lowercase, so an input like ALICE@EXAMPLE.COM with a non-ASCII letter kept its original case while a consumer applying Unicode lowercasing would not — two preimages for what users would read as one name. The specification closes this through the §4.3 grammar ("admits only ASCII"), but only if the grammar is enforced. Validation now runs after lowercasing, as §4.3 prescribes, and fails closed: exactly one @, non-empty local part limited to a-z0-9-_. with no leading, trailing or consecutive dots, and a DNS hostname domain (labels non-empty, a-z0-9- only, no leading or trailing hyphen, label <= 63, total <= 253). No Punycode or IDN conversion — the grammar is ASCII. Every rejection has its own named SpecError so a caller can tell which rule it broke. The V.12 fixture is unaffected: alice@example.com is conforming and the generated vectors file is byte-identical. * ci: pause hosted CI while the v1 rebuild is verified locally The rebuild is developed and checked on the build host; hosted CI is out of the loop until it is finished and is switched back on as the last step before the branch is offered for review. Running it in between spends self-hosted M3 Ultra slots on a tree that is knowingly mid-flight, and its result is not something anyone acts on. Only the trigger changes. The pull_request event is commented out verbatim and the restore point is marked, so re-enabling is a deletion rather than a rewrite; workflow_dispatch stays so a run can still be started by hand when a specific answer is wanted. Every job, guard and gate is untouched, so the first run after re-enabling exercises exactly what it did before. The other four workflows are unaffected: they trigger on pushes to staging, develop and main, none of which this branch touches. * fix: close four findings from the cross-vendor review network was accepted as any non-empty string when framing a name consent, so name_consent_preimage("Regtest", …) or ("mutinynet", …) produced a well-formed preimage over which the seed holder then signs. §4.3 and §7.3 define it as the closed set {mainnet, testnet, regtest}; it is now validated against exactly that, with the labels derived from the existing NETWORK_TAG_* constants rather than retyped. The BIP-340 negative test asserted only is_err(), which passes on any verification failure whatsoever — the form this project forbids, and one this branch introduced itself. It now pins the cause. Two guards in state_engine could never fire. leaves_from_sets writes every spent_id as Spent and then every spendable key as Admitted, overwriting it, so an input that passed the earlier "not spendable" guard is Admitted by construction. Both are removed, each with a note saying where the invariant actually lives, because the check they appeared to perform was missing elsewhere: insert_account compared only the supplied tree's root against AccountState.coin_history_root. It now also refuses an overlapping spendable/spent pair and requires the *reconstructed* root to match — the same pair the DB loader already enforced, which matters because the tree is not persisted and reconstruction is authoritative. The third dead guard stays. It is defensive code over a decision the control flow already fixes, and unlike the other two it masks no missing check; a comment now says so. Deleting the legacy repeat-send test left the second-send lifecycle without cover: the current end-to-end finalises exactly one send. A new test drives a second begin_send from the change coin of the first and pins the rotated pubkey, the send counter and the change coin's Admitted state. * docs: add a local compose stack for the Stage-3 node Two services only: postgres:17 (the tag testcontainers and the README already use) and the node binary from the repo Dockerfile on 0.0.0.0:4242. Every value is derived from a panic site in the binary rather than guessed, and the file names that site in a comment next to each variable. Secrets and chain endpoints use `${VAR:?...}` so a missing one aborts at parse time instead of starting with a phantom default -- there is no compose-level PUBLISHER_KEY, no fallback Esplora, no invented circuit pin. Only genuinely optional operational switches (publish wallet, fee rate, RUST_LOG) use `${VAR:-}`, and each says why in place. The healthcheck probes GET /health (liveness) and deliberately not /health/ready: a node may be live while readiness is still 503 because Esplora is down or the prover is warming, and papering over that with a green container would defeat the probe. There is no `restart: always` for the same reason -- a boot failure has to stay visible. docs/local-stack.md carries the operator side: which variables are required and where each one panics, how to compute ZKCOINS_EXPECTED_PARAMS_IDENTIFIER from the canonical encoding, and the regtest circuit digests, which match generated_circuit_digests.txt in this tree. It also lists what the stack cannot do -- no bundled bitcoind or Esplora, no API layer, and the node still speaks HTTP rather than the gRPC kernel edge -- so a green `compose up` is not mistaken for a working protocol. The API layer is left out on purpose: it is being built in parallel and does not run yet, and a service that cannot start would make the whole file useless. * test: generate the V.10 envelope preimages (coin_bytes, coin_plain) These were the last two spec cells still carrying a description instead of a value. Everything else in V.4 and V.11 has been filled for a while; the V.11 boundary suite for k = 0..63 lives in code rather than in a vector file because it feeds symbolic subtree roots instead of materialising leaves, which is what the section requires. The fixture coin is exactly V.4's coin.identifier@0: same identifier, recipient = the V.2 address, same amount, same asset_id. serialize_coin is the only layout source -- the generator does not rebuild the byte order, so the vector cannot drift from the function it documents. The amount is now bound once as amount_0 and reused for coin_identifier, the balance map and the Coin, where it used to be typed out three times. The drift gate was checked the only way that means anything: run before regenerating, and it fails (exit 101) because the generated text has two lines the committed file does not. Had it passed, the comparison would not have covered the new lines at all -- this project has already found five gates that could not go red, two of them vector generators reading back what they had just written. After regenerating, the same test passes. base64 joins as a dev-dependency of shared, only so the generator can call URL_SAFE_NO_PAD rather than hand-rolling an encoder. It was already in the workspace lockfile transitively. Cross-checked against the values already pinned: bytes 0..31 equal coin_identifier_0, 32..63 equal the address, 64..79 are 0x3B9ACA00 as a 16-byte big-endian amount, 80..111 equal asset_id; 224 hex characters total. coin_plain carries 150 base64 characters with no padding and no '+' or '/', so it is genuinely base64url. * refactor: extract a transport-neutral kernel layer, starting with GetJob The node is a kernel (section 6.1): gRPC only, never reachable from a public client, with twenty procedures fixed normatively in section 7.8. An attempt to wire those against the current code came back with zero of twenty, and the reason was not laziness -- the domain logic lives inside the HTTP handlers, not behind them. GetJob would have had to re-parse free-form JSON, StreamJob emits Event/KeepAlive rather than domain events, and the normative ErrorInfo contract cannot be guessed back out of an HTTP status and a free-text string. An independent design review confirmed the diagnosis and rejected the cheaper alternative -- putting gRPC directly over the handlers -- as "a second transport over a first, not an adapter over domain logic". It also found that only twelve of the thirty handlers carry domain logic at all: thirteen are pure transport (seven of them constant 410 Gone), and five belong in the API layer per section 6.1 and will move there rather than be duplicated. This is the first of eight blocks. It adds the foundation every later block hangs off -- typed job states, a strict row mapper, and the error contract -- and carries exactly one procedure all the way through. The kernel layer knows neither axum nor tonic; that is the whole point, and it is checked. Error codes are a closed enumeration with the normative reason strings, and the descriptor maps each one to both an HTTP status and a gRPC code, so neither transport has to invent anything. Operator detail rides in an InternalContext that is deliberately never serialised. Proving failure and publish rejection are not RPC errors at all -- they are successful results with a terminal job state -- and the enumeration says so where someone would otherwise add them. One behavioural change is intended. Until now a Completed job whose response_body was missing produced a 200 with the result field silently absent, and the same for awaiting_signature. A corrupt data state is not contract behaviour: "HTTP is unchanged" holds for well-formed states, and this is answered fail-closed with internal_error instead. That half answer, the one that looks like success, is the reason this refactor exists at all. Three tests cover it and would be red against the code they replace. Every existing get_job and v1_job_poll test still passes unmodified, and the public-surface allowlist does not move because the new modules are pub(crate). Verified locally: all ten steps green, 643 node tests and 130 shared tests passing. * feat: add the kernel.v1 gRPC skeleton, with every procedure unimplemented Section 7.8 fixes the kernel RPC contract normatively, and this commits it as an artefact: proto/kernel/v1/kernel.proto is taken verbatim from that block -- twenty procedures, message names identical, checked against the spec rather than retyped. Closed value sets stay as string because the spec says enumerated states use the literal section 7.5 strings. A new workspace crate, kernel-proto, generates the types and service stubs via tonic-build and holds no business logic. tonic is pinned to the 0.13 line because that is the last one whose tonic-build still owns prost codegen; 0.14 moved it to tonic-prost-build. The API repo declares 0.14, which is fine: separate processes speaking the same .proto agree on the wire regardless of crate version. Only a shared generated-types crate would force a single line, and there is none. Every one of the twenty procedures answers Status::unimplemented with its own name. That is deliberate and it is the opposite of a silent fallback. An attempt to wire them against the current code reported zero of twenty, with a per-procedure reason: GetJob would have to re-parse free-form JSON with no typed mapper, StreamJob is SSE rather than a gRPC stream, and SignTransition exists only as its verification stage while loading, rehydrating, finalising and the response shape sit in the HTTP handler. Filling five of them shallowly would have looked like progress and been a lie; a half Ok(...) is worse than an honest unimplemented. The HTTP router is untouched. Extracting the domain logic so both transports can call it is the separate refactor that began with the previous commit, and each procedure gets wired only when its block lands. docs/kernel-rpc-mapping.md records, per procedure, what exists today and what is missing -- so the next block starts from evidence instead of rediscovering it. Verified locally: all ten steps green, 648 node tests, 130 shared tests. * refactor: extract StreamJob and CancelJob, and wire the first three procedures Block 2 of the kernel/API split. The job event source becomes transport-neutral: SSE and the gRPC stream are now two adapters over one domain event, rather than SSE being both the transport and the event shape. GetJob, StreamJob and CancelJob answer over gRPC for real -- three of twenty; the remaining seventeen still say unimplemented with their own name, and docs/kernel-rpc-mapping.md records why for each. The eight `unwrap_or(Value::Null)` in the stream paths were the actual work, and they are not all the same bug. Three were masking: a Completed or AwaitingSignature job with no payload got a null instead of an error, which is the fault Block 1 already fixed for GetJob. Four were honest statements: proof_id genuinely does not exist yet while proving, and a failed job may legitimately carry no free-text error. One, the mid-stream result, is both depending on job status. They are now typed as Option up to the wire projection where they are statements, and fail-closed where they were masking. Two findings came out of this that had nothing to do with the extraction. start_kernel_grpc built a fresh, empty notify map, so a server booted that way accepted a StreamJob subscription, reported success and never emitted an event. Nothing in production called it -- main.rs boots through start_rest_node, which shares the dispatcher's map -- and the one test covering it only checked that the port could be bound, never that an event arrived. A silent stream is worse than an error because nobody notices, so the entry point is gone and the shared-domain path is the only way in; the allowlist loses two entries accordingly. The other was a wire regression: on a dead database the legacy cancel route started answering "Failed to load job" where it used to say "Failed to cancel job". The new text is arguably more accurate, and it is still reverted -- this refactor is an extraction, not a rewrite, and improving error text is a separate visible step. A systematic diff of the old and new handler surfaces (messages, status codes, headers, SSE event names, field order) found that this was the only outward-visible value that had moved. Verified locally: all ten steps green, 678 node tests, 130 shared tests, 95 prover tests. * feat: validate the normative error table at boot, and name what start_rest_node needs `KernelErrorCode` declares the closed §7.8 set so `describe()` is total from the start, but only the codes of the three wired procedures are constructed — so `dead_code` fired on fifteen variants. Silencing it per-variant would also silence the next genuinely unused one, and deleting variants would give up the completeness that is the whole point of the table. Instead the table is now checkable from library code. `KernelErrorCode::ALL` is the inventory (its length lives in the array type, so omitting a variant is a compile error) and `error_contract::validate_table` walks it to prove: - `describe(code).reason == code.reason()` for every code — the equality the doc comment previously only asserted in prose, - every reason non-empty and unique across all twenty-one codes, - `http_status` within 400..=599, - the eight `GrpcStatusCode` names non-empty and pairwise distinct. `start_rest_node` runs it before binding a listener and fails closed. The table is hand-written and both transports depend on it: a release built without green tests would otherwise ship the wrong code for every failure. The check costs microseconds once. Its effectiveness is itself tested — the same checker is fed deliberately broken rows and the assertions read the reported cause, so an empty implementation would fail them. Two smaller things the same lint surfaced: - `v1_status_wire` had no callers left. Both sites that produce the v1 status wire value go through `job.normative_status().as_v1_str()`, so the alias expansion (`queued`→`accepted`, `broadcasting`→`publishing`) is unchanged; the note about why the aliases live in one place moved to `from_store`. - `parse_job_request` returned `Result<_, tonic::Status>`, which is both a large error variant and the wrong layer — a parse function should not mint a transport status. It now returns `KernelError` and the callers convert through the existing adapter, byte-identical on the wire. `start_rest_node` took eight positional arguments, two of them optional handles. It now takes `RestNodeConfig`, destructured in the function head so a future field is a compile error rather than a silently ignored value. Every parameter doc moved to its field. `runtime_tests.rs` comes along for the call site, and with it the test lock moving to `tokio::sync::Mutex`: holding a thread-bound guard across an await is what the lint objects to, and the deliberate poison recovery is preserved for free because the async mutex does not poison at all. * fix: never report a successful cancel as an error `cancel_job` reloaded the row after a successful cancel so it could project a typed `Job`. The cancel is irreversible at that point, so a failing reload made the service report an error for an action that had succeeded — a client sees 500, concludes the cancel failed, and retries or escalates while the job is long gone. The legacy HTTP path answered `200 {"status":"cancelled"}` straight after `Ok(true)`, so it was also a behaviour change against "the HTTP surface stays as it is". The reload is gone. The already-loaded row is projected locally with the store's known cancel effects, which the SQL pins: cancel sets `status`, `phase`, strips the finalisation keys from `request_body` and stamps `updated_at` / `completed_at`; it leaves `error` and `progress` untouched. The domain projection reads status, optional error, phase, progress, kind and id — so the local projection is provably identical to a successful reload, and the second database round trip disappears. Two tests: one arms a test-only load-fail budget so the first load succeeds and every later one fails, then checks the cause is `Cancelled { error: None }` with `phase == "cancelled"` and `progress` preserved — against the old code that ended in `store_load_failed`. The other pins the projection helper without a database, so an invented `error` or a dropped `progress` is caught. `set_status_if` goes with it. The conditional status setter had no caller left: the finalise claim replaced it and is stronger, setting status, phase, owner, fence and lease in one statement bound to the expected status and `reset_generation`. The stale doc reference in `job_dispatcher.rs` pointed at the deleted method and is removed — the same table already names the claim. * fix: validate the commit/reveal pair before either transaction is broadcast The commit pays to a deliberately unspendable NUMS keypath, so the matching reveal is the only way to spend it. If the commit lands on chain next to a reveal that does not match it, the value is gone for good — real BTC on mainnet, and the publishing/nullifier state wedged behind it. The crash-resume path made exactly that reachable. It deserialises commit and reveal from the database and rebuilds a `PreparedBatch` from bytes that nothing has vouched for, then broadcasts the reconstructed commit immediately in the `constructed` state and both transactions again in `reveal_broadcast`. `broadcast_commit` checked only the anchor. Nothing anywhere checked the pair against itself. `PreparedBatch::validate_pair` now does, fail-closed, before any RPC: - the reveal has exactly one input, - its outpoint txid equals `signed_commit.compute_txid()`, - the referenced `vout` exists in the commit, - the commit output at that `vout` matches `commit_output` in value, `script_pubkey` and Taproot type. It is called at the top of `broadcast_commit` and `broadcast_reveal` — the only two `send_raw_transaction` sites in the publisher — and on the resume path before it hands a rebuilt batch to either. One method, not one copy per caller: a safety rule kept in two places drifts, and the next tightening lands in only one of them. The resume path additionally compares the persisted `commit_txid` and `reveal_txid` against the txids recomputed from the deserialised transactions, and refuses with a message that names durable state diverging from transaction bytes rather than a generic broadcast failure. Five publisher unit tests pin the rule itself; three resume tests pin that the send path applies it *before* sending, asserting the recording publisher saw no commit broadcast at all. That second assertion is the point — an error alone is not enough if the transaction already went out. Also here, because the same sweep found it: the receive slot-count limit was "tested" by `assert!(MAX_RX_COINS + 1 > MAX_RX_COINS)`, a tautology whose message claimed the length gate rejects an above-limit request. The gate exists, but the test next to it exercised a closure rebuilt inside the test rather than the production entry point. The limit now lives in `validate_receive_slot_count`, called by production with unchanged behaviour and by the test with `MAX_RX_COINS + 1`, checking the actual cause. The tautology and the test-local closure are gone. `ensure_segwit_funding` was a dead alias for the stricter `ensure_deterministic_funding`, which runs at UTXO selection and again before the commit is signed. Deleted; it accepted nothing the stricter check rejects. * ci: lint every target, and fix the sixty-three findings that had been invisible Three of the clippy steps ran without `--all-targets`, so clippy only ever saw the library targets. Several thousand lines of test, benchmark and fixture code had never been linted at all, and `shared/src/spec_v1/nflog_boundary.rs` sits behind the `test-fixtures` feature, so a plain `-p shared` run did not compile it either. Adding `--all-targets` to all three steps surfaced sixty-three errors under `-D warnings`. The lint job also installed 1.81.0 explicitly and exported `RUSTUP_TOOLCHAIN`, which overrides the `rust-toolchain` file every other job uses. Formatting and lints were therefore checked on a compiler seventeen releases older than the one that builds and tests the same tree — where a clippy suggestion can name an API the build toolchain has and the lint toolchain does not. It now installs the pinned toolchain, so there is a single pin with nothing to drift. This part cannot be verified locally while hosted CI is paused. Most of the sixty-three were style, but four were not, and two of those are worth naming: - Two branches of the lenient consistency-witness adapter were identical, and `ZERO_HASH` means different things in them: with `b` true the base slot is unread (the circuit picks `mth_a`), while with `b` false and an empty proof it is a deliberate poison value for a negative test. Written as one `if` plus `split_first`, the distinction is visible. The case `b = false` with an empty proof turned out to be untested — the boundary suites truncate a proof by one element, which never empties it when a terminal base plus a sibling are required — so it has an explicit negative test now. - `is_transient_scanner_race` and its error list were the retry tolerance of a second-send test against the live API. They went dead when that test was rewritten into a post-cutover 410 pin, not because the underlying scanner indexing race was fixed. Deleted here as dead code; the race and the coverage gap it leaves are recorded in the branch notes and addressed separately. `published_at`, `ensure_v1_attest_path` and six dead helpers in the live E2E suite are gone the same way — each traced to the commit that removed its last caller before deleting it, rather than kept behind an attribute. Two integer comparisons in the scanner (`size >= size_before + 1`) became `size > size_before`; both operands are `u64` and `size_before == 0` is reachable, where the two forms agree and the rewritten one cannot underflow. The two `type` aliases introduced for complex types are private, and neither allowlist moves. No `#[allow]`, no `#[expect]` and no `#[ignore]` was added anywhere in this change. * fix: gate job completion on the publish handoff, and stop deriving codes from message text Three defects on the same path, found by asking why a dead retry helper had lost its caller. **A job reported `completed` while its nullifier was unpublished.** The direct receive path persists the engine state and then publishes. The production job path used a different helper: it persists the `members_ready` row atomically and does not publish — and that stage-only helper was the installed runtime hook. The dispatcher then completed the job through the fence. The only production resume of pending publishes ran once at scanner start, so a row created during normal operation could stay unpublished until the next restart while the job claimed success. Worse, every follow-up job for that account then failed closed, because a predecessor nullifier that is not in the canonical NfLog is correctly refused — a dependency that could not be satisfied without a restart. The finalise host edge now publishes the row it just staged, reusing `durable_publish_nullifier` rather than a second path, and the fence completion is gated on that handoff. Order is unchanged and now enforced: persist, then publish, then complete. A failed handoff leaves the `members_ready` row intact and the job not completed. A periodic in-process resumer picks such rows up without waiting for a restart, and the boot check moved ahead of the REST spawn so a node that cannot determine its own pending publishes accepts no work at all. **A retryable condition surfaced as a proving failure.** §7.5 wants `409 dependency_not_final` with wait-and-resubmit. The classifier recognised the code only when the internal message happened to contain that string, which the engine message does not, so it fell back to `proving_failed`. The engine now returns a typed `DependencyNotFinal` carrying which of the two spec cases applies, and the classifier downcasts instead of substring-matching. `publish_rejected` went the same way in the same change — it was introduced as a string prefix here and would have been a new instance of the pattern rather than inherited debt. The message texts stay as diagnosis; nothing reads them for contract any more, and a free-form string with the same wording is now explicitly tested *not* to classify. The remaining substring branches (`unknown_publisher`, `invalid_input_coin`, `insufficient_balance`, `bounds_exceeded`, `circuit_digest`, `internal_error`) are inherited and deliberately left as a visible separate step. **Naked status writes could strand the fence owner.** `set_status` and the legacy completion paths checked `reset_generation` and non-terminality but no `from`. Generation guards against writes from before a reset; it does not guard against a competing transition inside the same generation. The claim code is explicitly multi-process, and nothing enforces one dispatcher per database, so a process holding a stale `queued` view could later write `proving` or `failed` onto a row another process had claimed — after which the rightful owner could no longer renew its lease or complete, while the transition it had already applied would still be published on the next resume. The client would see a failed job whose effect landed. Every such transition now carries a `from` predicate, and the store additionally refuses to touch a row in `finalise_claimed`. `from` is a required parameter, not an `Option`, so no caller can opt out. Every conditional write's return value is now read: a write that did not hit emits no phase event and reports no success — the attest path previously published events for updates SQL had not performed. The regression test drives two store instances: A holds a stale view, B wins the finalise claim, and each of A's formerly naked writes must return `false` with status, phase, owner, fence, lease and generation all unchanged, after which B can still complete. Three host-edge tests moved to the new contract; each now asserts both that the job is not completed and that the `members_ready` row survives, and the crash-resume assertion they carried is preserved. Two smaller corrections in the same tree: four prover-allowlist lines named enum variants and their fields, which the surface extractor does not emit for enums (it walks only inherent impls) — the enum path itself was already correct. And the fence regression test asserted `response_body.is_none()` where it means "unchanged": the fixture legitimately carries a signing payload from `set_awaiting_signature`, so the test now snapshots both fields before the late writes and compares for equality, which is the stronger claim it intended. * refactor: extract SignTransition, quarantine the legacy commit path, and close two fail-opens `jobs_sign_handler` was 249 lines carrying the whole of it: load, phase check, rehydrate, sign-to-contract and BIP-340 verification, durable persistence and the dispatcher handoff. The domain operation now lives in `kernel/jobs/sign.rs`, transport-free, and the handler is the HTTP projection of it. `SignTransition` is wired over gRPC as well — **4 of 20** procedures now. The crypto is reused, not reimplemented: `accept_wallet_transition_signature` stays the verify stage untouched, including its strictness. The ordering that matters is preserved step for step, because getting it wrong either loses an accepted signature or accepts one that is nowhere durable: load, phase check, rehydrate, verify, **refuse if no dispatcher exists** (before any persistence), install in memory, persist under a status CAS on `awaiting_signature`, then signal the handoff, then wake. Losing the handoff CAS after persistence is still a deliberate error with the signature durable — the existing timeout test pins that. The b2f lesson applies here too and is now structural: the job projection runs *before* any durable effect, so nothing fallible after the irreversible point can turn a success into an error. On success the pre-computed `Job` is returned with no reload. `jobs_commit_handler` — the legacy `ash‖ocr` compatibility path, not the §3.2 contract — moves to `application/legacy_jobs.rs`, quarantined rather than folded into the normative service. That the legacy path cannot finalise a v1 transition is structural at four layers: the entry refuses under v1, legacy only ever writes `request_body.commit` and never `finalisation`, the flows refuse again, and `drive_v1_finalise` requires a signature on the durable capability which only `/sign` writes. Two fail-opens closed on the way: - `wait_for_commit` matched `if let Ok(Some(job))` and `if let Ok(Some(entry))`, collapsing "does not exist" and "could not be determined" into one branch — so a transient database or rehydrate error fell through into the legacy commit branch. The hard boundary held only because gates further down catch it, which means a database hiccup was deciding the path. Load and rehydrate errors now fail closed and named; `Ok(None)` is handled as its own case. The success path is line-for-line identical. The audit table for the rest of the function is in the branch notes: two more masking sites outside this function are recorded, not silently fixed. - gRPC `SignTransition` had no feature gate, where HTTP refuses with `feature_disabled` when the v1 flag is off. It called the domain with `V1ShadowMode::On`, so a legacy stack answered `internal_error` for what is simply an inactive surface. The gate now sits at the gRPC edge before parsing. `feature_disabled` deliberately is not a `KernelErrorCode` — it is an API-layer gate — so the refusal is `Unimplemented`, like the seventeen unwired procedures, and the message carries the flag name so a caller can tell "not wired yet" from "switched off". `docs/kernel-rpc-mapping.md` says so. The kernel facade is uniform again: every re-exported type is imported through `crate::kernel::` rather than half of them through the submodule path. New domain tests cover persist-before-signal, no dispatcher, handoff timeout after persistence, and `wrong_phase` / `stale_message` / `invalid_signature` by cause rather than by `is_err()`. The gRPC width checks pin 64 and 32 bytes exactly and name the required width when they fail. No existing `jobs_sign_*` or crash-resume test was changed; the one test that moved is the gRPC skeleton's empty-`SignRequest` case, which now claims v1 first because the gate is deliberately checked before the width. * feat: extract SubmitTransition, and reject an idempotency key reused with a different body `jobs_mint_handler` and `jobs_send_handler` carried the normative validation inline. `kernel/jobs/submit.rs` now holds it, behind a closed `TransitionCommand` whose variants make the §7.5 presence matrix structural rather than checked: a `Mint` cannot carry `input_coins`, a `Receive` cannot carry `output_templates`, and publisher case (b) with a `fee_address` — which §7.5 forbids for receive and for a fee-less mint — is not representable at all. The transport rejects it as `malformed_request` before the type is built. `SubmitTransition` is wired over gRPC; **5 of 20** procedures now. **The idempotency defect.** `JobStore::create` returned the stored job for a repeated key **without comparing the body**. Two different requests under one key both got `202`, both describing the first request's job — the caller believes its request was accepted when a different one was. §7.5 requires `409 idempotency_conflict` for that case, and the code was already in the closed error table. The comparison is structural equality of the stored `jsonb` after stripping the four server-owned keys (`finalisation`, `pending_sign`, `sign`, `finalise_claim`), which cancel and finalise remove — a retry against an already stripped row must not read as "different". A raw byte comparison would be too strict (key order, whitespace); re-parsing into types would silently ignore unknown client fields. The check runs inside the same transaction as the `INSERT … ON CONFLICT DO NOTHING`, under the generation lock with `SELECT … FOR UPDATE` on the conflicting row, so there is no window between deciding and answering. Same key with the same body replays exactly as before. **`kind = "receive"`.** The job kind is closed to `mint | send | receive` (§7.8), but the `jobs.kind` CHECK did not allow it, so the store could not persist one. Migration `0029` widens it, additively, exactly as `0025` did for `attest_balance`. Wiring the dispatcher to it turned out to be the wrong move, and the reason is in the receive flow itself: `V1ReceiveRequest` requires every clause-10 slot — the coin, its creating proof, output inclusion, `creating_prev_ash`, the nullifier opening, NAV inclusion, `pos_create`, the NAV opening and the consistency proof — while a `SubmitTransition` command carries `fold_coin_ids` and nothing else. The type's own comment says a receive that cannot supply clause-10 material is not expressible. Half-wiring it would have accepted work the service cannot perform. So both honest halves: `SubmitTransition` refuses `kind = receive` **before** creating a row, and the dispatcher fails any such row that exists terminally with a typed `ReceiveJobPathNotWired` cause rather than skipping it. Which matters, because that skip existed: `(Receive, Queued)` would have landed in the dispatcher's `_` arm, logged at debug and returned `Ok(())`, leaving the job `queued` forever with nothing visible anywhere. That `_` arm is gone. The `(kind, status)` decision is now a named table — `SkipConcurrentProving` and `SkipConcurrentBroadcasting` for the two states that legitimately belong to another in-flight worker, `RejectReceiveNotWired`, and `FailUnexpectedNonTerminal` for everything else — and the test walks four kinds × seven statuses × both v1 flag settings. Nothing falls through silently any more. The two `match`es the new variant broke had no `_` arm, which is why the compiler forced a decision on each: `JobKind::Receive` maps to the wire string `"receive"`, and the commit-outcome arm says loudly that receive has no commit leg rather than inventing a placeholder. * feat: add the challenge store, AttestBalance and IssueViewGrant, with one domain separator Block 5 of the kernel cut: authorisation rather than state transitions. A challenge is a single-use secret, an ownership proof is what says the caller controls the account, and a view grant hands someone else read access to private data — so the failure mode here is disclosure, not a balance error. `ChallengeAction` is closed, and the binding to the action is **structural**: the store keeps one map per variant, so a nonce issued for `AttestBalance` is simply not findable when redeeming for `IssueViewGrant`. There is no `action: &str` compared after the lookup. Consumption is an atomic `remove`, so two concurrent redemptions cannot both win — the test asserts both outcomes, not just the winner's. The TTL is 60 s per §5.1, and it now lives in exactly one place. **The domain separator existed twice.** `v1/attest.rs` had `ATTEST_BALANCE_CHALLENGE_DOMAIN`, which is the value that actually goes into the signed `chal` and into the challenge response; `ChallengeAction::domain()` returned the same string and was used by nothing. Two sources for one authorisation boundary, one of them inert: if they drift, the boundary moves and nothing says so. `ChallengeAction` is the closed set and is now the definition; the constant derives from it. A test pins both strings verbatim and that they differ — pinning one would not catch the drift. **A gap, named rather than papered over:** §5.1 specifies an `IssueViewGrant` ownership proof over `chal = H("zkCoins/v1/IssueGrantChallenge" ‖ nonce ‖ chan_bind ‖ subject ‖ expiry ‖ request_hash)`. Nothing builds or verifies it. The structural action binding in the store is there, but the cryptographic domain separation on the grant path is not. It is not reachable today — no route issues grants, and the gRPC surface deliberately carries no ownership-proof field — but it is written down here so the API layer cannot assume the kernel already checks it. A grant currently unlocks nothing at all: `Pull`, `GetRecord` and sessions are a later block, and without an entrusted bundle the path refuses before consuming the challenge. A `GrantProof` cannot authorise either procedure, and the refusal does not depend on check order: the capability kind is a closed enum matched exhaustively, so "read access is not ownership" is decided by the type rather than by which validation happens to run first. Along the way, five things the sharp gate caught: - Bech32m existed once, for addresses with a fixed 32-byte payload. A view grant needs a different HRP and a variable length, so the grant encoder had reached for the `bech32` crate directly in a crate that does not depend on it. §1.7.7 is a spec encoding and those live in `shared`: it now has generic `encode_bech32m` / `decode_bech32m`, the address helpers delegate to them without changing behaviour, and there is one implementation rather than two. - Seven symbols in the new code were dead in the library target. Each was checked for being a wiring hole before being deleted — `ChallengeStore::len` turned out to be one: the missing test was that redeeming actually removes the entry, so that test exists now. `SCOPE_NOT_AFTER_UNBOUNDED` was needed, not surplus, and is pinned to §5.1's `2⁶³−1`. `GrantProofRejected::into_kernel_error` was a second mapping for one cause; the attest path now uses only it. - The facade re-export lists took four rounds to settle, because each fix moved the conflict one level up. The rule is now written above them — what is in the list is used through it, and what is used through it is in the list — with the per-target caveat that a name used only from `#[cfg(test)]` does not keep a library-target re-export alive. - `prover_bridge.rs` asserted 1,403,783 compliance gates and 193,437 balance gates. A real release build of all six circuits measured **1,382,481** and **191,268** — the values pinned since the limb redesign, which the same run confirmed the live circuits still match digest-for-digest. The test was red and invisible: excluded from the local chain as heavy, and hosted CI is paused. It also carried no `#[ignore]` while building real proofs, unlike the five comparable tests. Both assertions now read the pinned file, so a circuit change makes one place red instead of two where one stays quiet. - The test asserting that gRPC carries no ownership-proof fields compared the raw proto text, and failed because the file *documents* that rule in four comments. It now strips comments first, and a second test feeds it a genuinely declared `bytes ownership_proof = 9;` to prove the check still catches one — otherwise the fix would only have been "test goes green", not "test checks". The existing attest route and digest-gate tests are unchanged, including the `circuit_digest_mismatch` 503 gate. * feat: add the read-only chain procedures, and refuse to invent an inscription txid Block 6: `GetInfo`, `GetAccumulator`, `GetNullifierPath` and `ListInscriptions`. These carry no authorisation and change no state, but they are the only surface on which somebody outside can check that a transition really landed — a job reporting `completed` proves the transition was applied locally and handed to the broadcast path, not that it is in the canonical chain. So the standard here is different: an answer that looks plausible without being bound to the canonical source would be worse than no answer. The NAV root is always `Hc("NfLog/Root", size ‖ mth)`, taken from the one function that builds it; a test rules out the bare `mth` and a swapped composition, because two identical calls agreeing proves nothing. The page cursor is all-or-nothing by construction — `Exhausted` or a complete `(height, tx_index, vin_index)` — so a half-filled cursor is not representable rather than rejected after the fact. `GetNullifierPath` distinguishes absent from present, returns a path that verifies against root and size, and **`present: false` can never come from an error**: a corrupt index or a failing inclusion path is `internal_error`, with a test that pins exactly that. **`ListInscriptions` answers `Unimplemented`.** The first implementation filled the reveal txid with an `UNKNOWN_REVEAL_TXID` constant and guessed the §3.5 format, because the NfLog stores neither. Answering without those fields is not honest either: they are proto3 scalars without `optional`, so an empty `bytes` is indistinguishable from unset, and `format = 0` is the valid value "raw" — a caller cannot tell a missing fact from a stated one. The procedure therefore says what is missing: a scanner-written inscription catalogue carrying the reveal txid and the format. Canonical membership of a nullifier is already answerable, and answerable properly, through `GetNullifierPath`. The pagination logic went with it. It was correct and tested, but after the placeholder path was removed it was reachable only from `#[cfg(test)]` — tests confirming code the running service never executes, which is the same "looks covered" shape being removed elsewhere in this branch. The contract it encoded is in the module documentation instead: a total stable order on the triple, a cursor that is complete or absent, and gapless continuation between pages. The catalogue rebuilds against that. Two more surrogate values, named rather than left to look like measurements: `scanner_lag` is 0 or 1 derived from a catch-up flag, not a height delta; and `ChainIdentity` is `None` in production, so `GetInfo` fails closed across all of its fields rather than returning a partial `Ok` with invented relay URLs. `info_handler` and `ready_handler` are untouched, and their goldens with them. The one deviation found on the way is reported, not fixed: `/api/info` says `mainnet` / `mutinynet` while §7.8 closes the set to `mainnet | testnet | regtest`. Changing the legacy REST field is a separate, visible step. The three closed §7.8 sets — `ReadyReason`, `NullifierMemberState`, `KernelPart` — follow the pattern `KernelErrorCode` established: an `ALL` inventory whose length lives in the array type, and a check that runs from library code at the boot edge before the listener binds, verifying every wire token is non-empty and pairwise distinct. Two states collapsing onto one token would be invisible otherwise. The effectiveness test feeds the checker a deliberately broken list, so an empty implementation would fail it. One test was fixed rather than weakened: it asserted that a wired procedure without an engine answers `Internal`, but sent `GetNullifierPath` an empty request, which correctly fails input validation first. Validating the request before touching state is the right order, so the test now sends a well-formed nullifier and reaches the path it claims to check. * feat: add session-bound private reads, and drop the subscription that could never deliver Block 7: `Pull`, `GetRecord`, `GetCoinProof` and `GetAccountState`. This is where private data is read, and where a view grant lets a *second* party read a slice of it — so every mistake here is a disclosure rather than a balance error. Ownership and grant sessions are a closed enum, and `GetAccountState` reaches ownership only through a match on the discriminant: a grant session lands in the rejection arm structurally, not because a check happened to run first. A slice of read access is not a right to the account state. The subject always comes from the server-side session. `RecordRequest`, `CoinProofRequest`, `AccountStateRequest` carry no subject field at all, and the domain command types have none either, so a client cannot name whose data it wants. `PullRequest` does carry one — it is authenticated by the API layer — and that is called out rather than assumed. Scope is enforced before canonical bytes are released, not by reading everything and filtering after: the list query is bound to `(subject, scope)`, a lookup for a foreign subject is `not_found` so existence is not leaked, and a record of the caller's own subject outside the asset or time window is `scope_exceeded`. That split is the privacy statement — a grant holder already knows the subject, so it gets a scope boundary; a stranger gets no confirmation that anything exists. Unknown, expired and wrong-`chan_bind` sessions all answer `session_expired` / 410, matching §7.5, which deliberately collapses them; a missing bearer is `unauthorized` / 401, a different class. Sessions do not slide: a lookup does not extend the expiry. **`SubscribeReceipts` is `Unimplemented`, and the receipt machinery is gone.** The hub, the filter and the subscription were all built, but nothing published: no production writer feeds verified credits into the hub after the durable persist §4.8/§4.9 requires. A subscriber would have received a successful response and then silence — the same shape as the gRPC entry point in an earlier commit that accepted subscriptions against a freshly built empty notify map. The procedure now says what is missing instead. The contract the future writer has to meet is documented where the refusal lives, including the point this case taught: a subscription may only be accepted if a writer exists. Removing it took three assurances with it. Two survive elsewhere — a foreign subject is still excluded from the pull listing, and a wrong asset is still `scope_exceeded` on `GetRecord` and `GetCoinProof`. The third did not: the grant time window was only ever covered by receipt unit tests, while the predicate kept guarding the remaining read procedures. An authorisation boundary with no test is exactly what goes quiet on the next refactor, so it is rebuilt on the procedures that remain — before the window, after it, and inside it, because testing only the two rejections would pass with everything refused. `OpenPullChallenge` is wired, which is what makes the chain reachable at all: before it, the pull challenge could be issued only from tests, so `Pull` and everything behind it was dead in production. `entrust` and `revoke` stay `Unimplemented` for the block that brings them. Two functions grew past seven arguments and are now named config types destructured in the head, as `RestNodeConfig` does, so a future field is a compile error rather than a silently ignored value. * chore: remove the rustc ICE dumps and ignore them Twelve `rustc-ice-*.txt` files went into the previous commit by mistake. They are crash dumps rustc writes into the working directory when it panics — here from a corrupted incremental-compilation cache after cargo processes were killed mid-build, not from anything in the tree. They carry local paths and no value to anyone. Removed, and `.gitignore` now covers the pattern so the next ICE cannot ride along in a commit. * feat: add Publish, EntrustOperationalBundle and RevokeOperationalBundle Block 8, the last of the kernel cut. **20 of 20** procedures are now either wired or state precisely what they are waiting for. **A rejected publish stays a successful RPC.** The network declining an inscription is a result, not a transport failure — the same separation the job side already makes, where `ProvingFailed` and `PublishRejected` are terminal job states inside a successful `GetJob` rather than RPC errors. `Publish` returns `Ok(Rejected { reason })` or `Ok(Accepted { batch_eta })`; `Err` is reserved for a malformed request or missing infrastructure. `reason` is a closed set of nine, not a free string, with the inventory and the boot-edge check every other closed set in this branch uses: each wire token non-empty and pairwise distinct, because two reasons collapsing onto one token is invisible otherwise. The same treatment reached `PublishPolicy`, whose `DeclineFeeLess` arm was declared but never constructed — §3.8 and §7.6 make it a real case (a publisher may decline a fee-less hand-off by policy), so it stays and is now checked rather than silenced. **Fee fields fail closed.** v1 publishing is sponsored and the fee-coin case is deferred, so `fee_blob_id`, `fee_epk` and `fee_blob_locators` must be absent. A set fee field is rejected as `malformed_request` before the command is built — not ignored, and not turned into a policy rejection. Same line as `fee_address` on `SubmitTransition`. **The operational bundle is exactly 161 bytes**, and the doc comment carries the decomposition (`1 + 5×32`: version, `ivk`, `ovk`, `op`, `nk`, `op_secret`) with a const assertion, so the number is checkable rather than merely stated. A wrong length reports both the expected and the actual one. The entrust path also locks the layout — `serialize(parse(wire)) == wire` — which is what catches a field order swap; without it the round trip was only implied by a sample fixture. **Revoke is irreversible and its nonce single-use.** The challenge nonce lives in its own action map and is consumed by an atomic remove, so exactly one redemption wins; the bundle slot moves `Active → Revoked` by compare-and-swap and leaves a tombstone, so a later entrust for the same subject is refused structurally rather than by a check. The order is redeem, then tombstone, then answer — nothing fallible runs after the irreversible step where a failure could hide a success that already happened. The concurrency test asserts both outcomes. No SPEND-branch secret can cross the kernel boundary: the proto audit covers the field names, and a test pins it. The entrust bundle carries view/op/nk material, `PublishRequest` carries public nullifier points and scalars, and `SignRequest.signature` is a signature rather than a key. Two blocks turned out to already meet: `issue_view_grant` reads `op_sk` from the same bundle store that entrust writes, so a grant without an entrusted bundle fails closed rather than silently signing with nothing. * docs: add the build report, and correct the RPC mapping to 18 of 20 The Implementation Mandate §4 points at a build report as an artefact. It did not exist — the docs repo's F-08 status matrix names it as missing, so the evidence column there pointed at nothing. It exists now, from three real runs rather than estimates. Circuits, identical across all three networks: `C` at 1,382,481 gates and degree_bits 21, `C_balance` at 191,268 and 18. Six real builds (both circuits × mainnet, testnet, regtest) took 2 h 39 min at 88.3 GiB peak RSS, and all six digests match the pinned `generated_circuit_digests.txt` — the live circuits are provably the ones whose digests are in the spec. A real end-to-end proof (mint + send + receive) took 52 min at 88.9 GiB. The circuit test suite — 166 tests covering every compliance-clause negative, the clause-10 receive, `C_balance` with its eight negatives, and the NfLog gadget boundary suite across `k = 0…63` — passed completely in 3 h 01 min at 92.5 GiB. The report says three things the numbers alone would not. Memory is the binding constraint, not time: 92.5 GiB is 72% of this host's RAM, so less memory means less parallelism rather than a longer wait. The suite needs `cargo test` and not `cargo nextest`, because it shares the 1.4-million-gate circuit through a process-wide `OnceLock` and nextest runs a process per test, rebuilding it for each — the difference between three hours and unusable. And these runs were the first time the circuit suite had ever been executed: not locally, and not in CI, whose gates cover `-p node -p shared` only. It also states what it does not contain — proof size in bytes, verification time, the memory of a single proof separated from the circuit build, and any distribution, since these are single observations without repetition — plus the exact commands, so the runs can be repeated rather than believed. The RPC mapping said 15 of 20 wired, which was the pre-Block-8 state. Verified against `kernel_rpc.rs` procedure by procedure: **18 of 20**, with `Publish`, `EntrustOperationalBundle` and `RevokeOperationalBundle` added. The two that are not wired answer `Unimplemented` naming what they wait for — `ListInscriptions` needs a scanner-written inscription catalogue carrying the reveal txid and the §3.5 format, and `SubscribeReceipts` needs a writer publishing verified credits into the hub after the durable persist. `SignTransition`'s feature gate also answers `Unimplemented`, deliberately without the unwired-procedure wording, and is not counted as missing. * fix: put the normative ErrorInfo on the wire, not private metadata headers §7.8 is explicit: every failed `kernel.v1` procedure returns a `google.rpc.Status` whose `details` **must** include exactly one `google.rpc.ErrorInfo` carrying `reason`, `domain = "kernel.v1"` and `metadata["http_status"]`, and an independent API layer **must** map errors onto REST by reading those two fields rather than the free-text message. The node did not do that. It set three private metadata headers instead — `error-reason`, `error-domain`, `error-http-status` — while the doc comment above the function claimed it embedded an `ErrorInfo` detail, and a comment inside admitted the packing "is not yet wired". Two statements about the same function, one of them false, and the true one buried below the one people read. It surfaced from building the other side. The API layer reads what the spec prescribes, so against this node every domain error would have failed closed as `500 internal_error` instead of `404 job_not_found`, `409 wrong_phase` and the rest. Two sides, two contracts, and neither would have looked broken alone. `ErrorInfo` is now packed properly via `tonic-types` at the same 0.13.1 line as `tonic`, from the same `error_contract::describe` table — there is still exactly one vocabulary. After packing, the status is read back and checked: a missing or wrong triple logs and produces a normative `internal_error` rather than a status with an empty detail. The metadata headers are gone. They were not specified, and while they existed a client could read them instead of the detail — which is precisely the dual contract this commit removes. A client that cannot decode `Any` should learn the standard richer-error path, not a private header convention. Streams follow the same rule (§7.8: a failing server-stream ends with the same `Status` + `ErrorInfo` shape, no stream-only error vocabulary). Every domain path in `StreamJob` — at open and mid-stream — goes through the same mapping, and an integration test pins that the stream terminates in that form. Tests cover six codes including both 410 special cases: `challenge_expired` and `session_expired` share `UNAUTHENTICATED` with `unauthorized` but must not collapse to 401, which is exactly the kind of detail a hand-written second table gets wrong. Further tests pin that exactly one detail is attached — not zero, not two — and that `InternalContext` reaches neither the message nor the detail bytes. * feat: wire ChainIdentity from operating configuration so GetInfo can answer `GetInfo` was built in an earlier commit and then never able to succeed: the runtime set `ChainIdentity` to `None` — correctly, rather than inventing relay and blossom URLs — so the procedure failed closed in production, and with it the API layer's `GET /v1/info` and `GET /health/ready`. Failing closed was right while nothing could supply the values. But a fail-closed nobody can ever resolve stops being a safety behaviour and becomes a surface that does not exist. The difference is whether anyone knows what to do about it. The identity now comes from three distinct places, and which one each field comes from is a decision rather than a habit: - **Operating configuration** for what an operator legitimately chooses — the relay URL, the blossom URL, the blob size limit. These are required environment variables with no default: a missing one aborts startup naming the variable, the same line already taken for the kernel gRPC address and the pending-publish boot check. `compose.yaml` uses `${VAR:?…}` so the failure happens at parse time. - **Protocol constants** stay in code. An operator must not be able to set them, because a wrong value there makes the node lie about the protocol rather than about its own deployment. - **The running node** supplies what it already knows — the circuit digests come from the same source the digest gate compares against, not from configuration. **The signed bootstrap manifest is deliberately still missing**, and the report says exactly what for: there is no BMF1 codec, no loader for a signed artefact, and no signing in the node — which must not be invented, because a manifest the node signs itself proves nothing. That one field therefore keeps its part of `GetInfo` fail-closed, with the path to closing it written down instead of approximated. * docs: put bitcoind in the local stack, and write down what a full run needs The header of `compose.yaml` said the API was "not runnable yet" and bitcoind was "external". Both were true when written and neither is now — which makes them the most durable kind of wrong: a comment somebody wrote deliberately, and therefore one people believe. bitcoind joins the stack on a pinned image, because without a real chain the stack cannot demonstrate the thing that matters. A job reaching `completed` means the transition was applied locally and handed to the broadcast path; chain inclusion, the scanner fold and finality all need blocks. The node reaches bitcoind over RPC — `ZKCOINS_V1_BITCOIND_RPC_URL`, the cookie path and the wallet name, read off the boot path rather than assumed, with no Esplora fallback for scan or publish. No wallet is pre-seeded and no blocks are mined by a container command: generating state belongs in the instructions where it is visible, not in a startup line. The API is **not** a compose service, because its repository has no Dockerfile — so the documentation says to run it against the mapped kernel port instead of inventing a build context for a directory that is not there. Its four required environment variables are read from its own config module, not guessed. `docs/local-stack.md` is now a walk-through for a complete run rather than for "the stack starts": prerequisites and an honest word about the first circuit build, every variable and where its value comes from, a checkable readiness condition per service instead of "wait a moment", then mint, sign, follow the job, mine, and prove the nullifier through `/v1/chain/nullifier/`. It states what the run proves and what it does not — `completed` is not chain inclusion, which is exactly why the last step exists, and one block is not finality. Four things are marked open rather than filled in with something plausible: the wallet-side derivation and the signature for the `awaiting_signature` step, since **there is no signer in this stack**; which 32-byte pubkey a mint puts into the nullifier lookup; an Esplora instance for the same regtest, still needed by the residual boot path; and `GetInfo` staying fail-closed until a signed bootstrap manifest exists. A walk-through with one invented step costs more time than one with a stated gap. * feat: write the inscription catalogue at fold time and answer ListInscriptions from it ListInscriptions was Unimplemented because the NfLog cannot carry what §3.5/§7.8 require of an inscription: it stores winning (pk, r) pairs and a chain position, not the reveal txid and not the format byte. A projection over it would have had to invent both, and a proof surface that invents a value is worse than one that refuses — the caller queries it precisely because it does not want to trust the job status. The scanner now emits a record per accepted inscription (§3.6 steps 1-3 passed) alongside the per-member nullifiers: reveal txid, §3.5 format byte, member pairs, chain triple, block anchor. Migration 0030 stores head and members in two tables with a foreign key and ON DELETE CASCADE, so a reorg can never leave half an inscription behind. Three properties make the catalogue usable as evidence rather than decoration: - Catalogue and NfLog are written in the same transaction and truncated together on reorg. Two separate writes would let the proof surface drift from the truth it is supposed to attest. - The catalogue carries double-spend losers. The NfLog does not admit them (DuplicateIgnored), but they were inscribed on chain. The catalogue records what was inscribed; the NfLog records what won; the answer marks the difference as `failed`. A catalogue that only repeats the log cannot corroborate it. - The survivor stream is derived from the accepted inscriptions rather than taken separately, and the coupling is checked before the mutate. Previously a decoupled pair would have folded the NfLog against an empty catalogue and stayed silent. The reveal txid is stored in internal byte order (§7.8), which is the reverse of the Display form; a test distinguishes the two, because a swapped txid looks like a txid in every other test. 19 of 20 kernel procedures are now wired. SubscribeReceipts stays Unimplemented and names its prerequisite. * feat: add the BMF1 bootstrap manifest codec and a loader that verifies it GetInfo could name the network's seed infrastructure only if something could supply it, and nothing could: there was no codec, no loader, and no signing. The codec follows the §7.7 framing byte for byte. One function writes the body `network … expires_at`, and both derivations feed from it — `serialize` frames it with magic/version/signature, `bootstrap_message` hashes it under the domain tag. Two separate framings would drift, and the drift is invisible until a foreign implementation verifies against ours. `manifest_id` is over the full serialisation including the signature; a test asserts the two digests are built over different bytes, because "both are 32 bytes" proves nothing. Verification runs the four §7.7 steps in order and takes the pinned `bootstrap_pubkey` from the frozen network parameter set — never from the manifest, never from the environment. `expires_at` is checked only when a clock is available, and "no clock" is a distinct variant from "time = 0" rather than a sentinel. `issued_at > expires_at` is rejected outright: it is the clock-independent form of the same degeneracy. Nothing in production signs. The pinned key is the only authority §7.7 permits for a network, and a node that signs its own manifest proves nothing about the network — only about itself. Signatures are produced in tests, from keypairs the tests generate. The bit-flip table binds every body field to the signature, and it is built on an exhaustive destructuring of the manifest: a field added later fails to compile until someone decides how it is covered. The base timestamps are chosen so a one-bit flip cannot make the lifetime degenerate, so no row can pass for a reason other than the one it names. The loader reads the manifest path from the operating configuration. Absent means no manifest — an honest state. Present means the artifact must load, decode and verify, or the process refuses to start, before a port is open, naming the variable and the reason. * feat: add the §1.3 note-encryption derivations and the ZBE blob format This is the crypto layer under the missing receive transport. It is the only one of its three layers (crypto, Nostr, Blossom) that can be proven without a relay, a blob store or a network, so it goes first: the V.10 fixture pins every derivation, and matching it bit for bit makes this a fact rather than an intention. Key derivations follow §1.1/§1.3: `ss` by ECDH under the x-only lift convention, then `K_tx`, `K_out` and `kb` through the §1.1 HKDF mapping. Both ECDH directions are implemented and a test puts them against each other — `x(esk·lift_x(IVPK))` and `x(ivk·lift_x(epk))` must agree, and an implementation that only ever tests the sender side looks correct until a receiver runs it. The `NIP44Binary` envelope carries its own base64url decoder rather than a permissive one. Padding, the standard `+/` alphabet, whitespace, an impossible length and any non-canonical re-encoding are rejected: a lenient decoder turns a closed encoding into an open one, and the field it feeds is assumed unambiguous elsewhere. Every §4.2.1 open-negative has its own typed rejection. ZBE (§4.2.1) is complete — chunked ChaCha20-Poly1305 at 64 KiB, a nonce over the chunk counter, an AAD binding both the index and the total count, `ZBE1` framing and the SHA-256 `blob_id`. The AAD is what makes a truncated or reordered ciphertext fail even when the frame is internally consistent: a sealed chunk carries the *original* `N`, so adjusting the header does not help. `zbe_open` cannot hand out a partial plaintext. The AEAD phase collects into a Result before anything is concatenated, so there is no code path on which the first k successful chunks reach the caller when chunk k+1 fails. The AAD prefix length is taken from the tag itself. It was a literal `14` next to a 15-byte tag, caught by a compile-time assertion — a hand-written length is a second source of truth that silently misframes every AAD the day the tag changes. chacha20poly1305 enters the workspace because §4.2.1 names the primitive and explicitly separates it from NIP-44 v2, which uses ChaCha20 with HMAC-SHA-256. * feat: the off-chain transport — Nostr, Blossom, delivery and receive This is the block every other open item was waiting on. A second opinion had established the shape: the receive job path is not blocked by its wire format (§7.5 asks for `fold_coin_ids` and nothing more, deliberately) but by the absence of a transport — no relay client, no blob store client, no decrypt index. Receipts, grant verification and recovery all hang off the same chain. Built bottom-up, each layer against somebody else's vectors: - **NIP-01 event core.** Its own canonical serializer, because NIP-01's escaping rule is *narrower* than any JSON library's: only `\n \" \\ \r \t \b \f` are escaped and non-ASCII passes through literally. A library that emits `\uXXXX` produces a different event id, and nothing notices until a foreign client rejects the event. - **NIP-44 v2** against the 118 official vectors — including the twelve `invalid.decrypt` cases, which are the ones that check that the *wrong* thing does not come out, and the 24 padding cases, which decide interoperability. - **NIP-59** seal and gift wrap. One check carries the layer: a rumor whose `pubkey` is not the seal's author is a forgery. Without it anyone can claim any sender. - **Relay client and pool**, verified against a real `nostr-rs-relay` in a container. A relay is an untrusted peer, so every inbound event is re-hashed and BIP-340-verified before it is handed on, subscription ids are matched against what this client opened, every wait has a timeout, and the pool returns one outcome per relay rather than an aggregated "it worked". - **Blossom client and the §7.4 auth event.** The content address is recomputed after every fetch and compared against the id the store returns on upload — without that, a store hands you bytes and you have no idea which. - **Profile resolution** with the §7.3 checklist run *as an order*. The test that matters presents a profile with a real address, valid signatures and a foreign `ivpk`: it is rejected at the `addr_sig` step, because `pk0` and `nk_commit` are public and anyone can publish a profile claiming them. - **§7.1 bundle codecs** with every malformed condition as its own case, so one bundle has exactly one byte string — the guarantee `blob_id` rests on. - **Delivery** (§4.2 steps 1–5) wired after durable persistence, never before; fresh `esk` per coin; exactly two cleartext tags on the outer event. - **Receive** (§4.4): pull all kind-1059, match locally, unwrap, fetch, ZBE-open, verify, persist, then acknowledge. Migration 0031 adds the durable decrypt index that `kernel/access.rs` has been documenting as missing. Two findings from running it rather than reading it: The `newer_replaceable` tie-break preferred the *higher* event id; NIP-01 keeps the *lowest*. Two clients seeing the same two profiles would have picked different ones — and encrypted to different `ivpk`. The test that should have caught it signed the same content twice and assumed the ids would differ, but the signature is not part of the id. A test asserted that a `#zkdt` filter returns matching events. The real relay returned nothing, and it was right: NIP-01 only indexes single-letter tags. §4.4 says so too — detection is deliberately *not* server-side filterable, and that non-filterability is what the privacy argument rests on. The receive path was already correct; the test encoded a property whose absence is the point. It now asserts the absence. The order in which the branch got here is recorded in the intern log. What is not built is named there too: self-delivery records, backoff republish, and the Invoice carrier that §7.5 does not define. * feat: wire the receipt writer and SubscribeReceipts — 20 of 20 kernel procedures `kernel/access/receipts.rs` has carried the writer contract and the reason it was not built: there was no production path publishing verified credits after durable persistence, and accepting a subscription without one would have opened a silently empty stream — worse than an honest Unimplemented. The receive path built with the transport closes that. It verifies an incoming bundle, persists it into the decrypt index, and only then acknowledges; the emission point sits at exactly that boundary. All four contract points are held and each has its own test: emission strictly after verification and durable persistence (a failed persist produces no receipt), the payload fields §7.8 names, filtering by the *server-side* session subject and resolved scope rather than anything the client sends, and a subscription accepted only because a writer exists. A lagging subscriber is dropped rather than buffered without bound — the stream is a latency accelerator and the client recovers missed receipts through the ordinary pull endpoint (§4.9). The writer never blocks on a subscriber, and the distributor does not sit between persist and finish: the finalise order is unchanged. The request carries no `subject`. Subject and scope come from the pull session the API opened, and a test asserts that a client-supplied subject changes nothing. * feat: recovery (§4.5) — the gapless scan and the fail-closed incomplete result Everything §4.5 needs was built with the transport: the relay client with NIP-01 filters and EOSE, the Blossom client that recomputes the content address, `ivk` detection, ZBE open, the bundle codecs, and the receive path with its §2.3.3 checks. Recovery is the orchestration on top — and its hard part is step 3. The obvious scan — lower `until`, keep going — works in every ordinary test and loses exactly the events one only loses once. NIP-01 has no exclusive `(created_at, event_id)` cursor, so if more events share a second than the page size, advancing `until` skips them. The implementation therefore never lowers `until` under a reached timestamp before proving that second fully drained through a limit-free `since = t, until = t` query, deduplicating globally by event id. Drain is not gated on a page returning exactly `limit`: NIP-01 may return fewer, and treating that as "there was no more" is the same bug wearing a different hat. Two tests carry the whole block: a relay double holding more events at one timestamp than the page size — all of them must be found — and one that caps the limit-free query, where recovery must report **incomplete** rather than step past the timestamp. Fail-closed here means saying the restore is incomplete instead of presenting a balance that quietly forgot some coins, and the failing relay's URL travels with that report so an operator knows where to look. The dense account enumeration of step 1 is *not* here, and cannot be: it needs `Pk₀(account)` from the SPEND branch `A/0'/i'`, which never leaves the wallet — the operational bundle a node is entrusted with explicitly excludes it. That part belongs to the wallet/SDK layer, and a doc comment says so rather than leaving a facade for it. The run itself is an operator action behind an operating-configuration variable. Without an entrusted bundle it refuses by name; there is no automatic scan on boot, because a node that sweeps every relay's full history on each start is an operational accident. * build: put the API in the local stack, and fix the compose file it never validated against The stack had four services and could not do a full run, because the API was not one of them — `docs/local-stack.md` told the reader it "runs alongside". With the API image in place it becomes the fifth service, with a readiness probe a human can check and every fail-closed variable named rather than defaulted. The healthcheck deliberately uses `/health` and not `/health/ready`: readiness is a GetInfo projection and stays 503 while the bootstrap manifest is fail-closed, so a `depends_on` on it would block the stack without saying anything about the REST listener. `compose.yaml` was also not valid YAML and had never been, so `docker compose config` rejected the whole file: the `:?` message on PUBLISHER_KEY contains `: ` inside an unquoted scalar, which YAML reads as a mapping separator. It is quoted now, and the comment says why — a stack file nobody can parse is a stack nobody has validated. * docs: write down how the full test suite is actually run Running `cargo test -p node -p shared --all-features` produces 132 failures on a healthy tree, and nothing in this file explains why. The cause is not a regression: `stack-policy` records the stack mode as a process-wide monotonic claim, a conflicting re-set panics on purpose, and the test-only reset is gated on `#[cfg(test)]` of the defining crate — so dependents cannot clear it from their own test binaries. Under one shared process a Legacy case and a V1 case collide, the mutex poisons, and every later test in that process fails behind it. Under nextest each test gets its own process and the collision cannot arise, which is why the CI gate drives nextest. This documents the command that matches the gate, why nextest is a requirement rather than a preference, and where the boundary runs: targeted single-mode subsets — including the existing `cargo test -p node db` line — stay perfectly valid. It also records two scope gaps rather than papering over them. The heavy prove flows live in `zkcoins-prover-plonky2`, which `-p node -p shared` does not select, so neither the recommended command nor the CI gate exercises the prove path; and four `#[ignore]` cases in `node` — the genuine-prove receive path, two concurrency cases and the prover-bridge pin-mismatch check — run neither locally nor in the gate. Both now carry the command that does run them, and the note that a run without them is not a complete verification. * fix: wait for Postgres to actually serve, not just to bind The shared test container's readiness check was guarded by `acquire_timeout(30s)`, which only covers timeouts. A half-started Postgres answers the socket with a protocol response sqlx treats as a hard error, so `connect()` gave up immediately and the thirty-second budget was never spent — the observed failure landed after 0.138s with `unexpected response from SSLRequest: 0x00`. The suite looked stable because it usually ran against a warm container left behind by an earlier run. Run it against a cold one and `test_load_from_pg_rejects_corrupted_blob` fails, taking the rest of the run with it. Run the same test alone and it passes, because by then the container is warm. That is flakiness, and it hid behind the reuse. Readiness is now a real retry loop under the existing `CONTAINER_READY_SECS` deadline. Transient conditions — the protocol and TLS responses of a booting server, refused and reset sockets, `57P03` (cannot connect now), `53300` (too many connections) — are retried with a 50ms backoff doubling to 2s. Permanent ones — configuration, invalid argument, closed pool, crashed worker, any other database error — still fail immediately and loudly; the loop must never turn an auth or config mistake into a thirty-second wait followed by the same error. `ReuseDirective::Always` is why a wait strategy on the container alone would not fix this: testcontainers skips wait conditions when attaching to a running container, so the log line it watches for is long past. The connect loop covers both the cold create and the attach. The classification is extracted and tested directly: transient inputs retry, permanent ones do not. * feat: give the kernel a real identity, and admit receive transitions Two places were structurally wired but semantically unfinished. Both were fail-closed, so neither was a live hazard — they simply blocked the end-to-end flow. `GetInfo` had no chain identity: the bootstrap passed `None` while the service required one, so `/v1/info` and readiness could never be answered. The identity now comes from the verified §4.3 BootstrapManifest, projected into the domain type, with the network it declares checked against the frozen §3.6 pin — a manifest disagreeing with the pin is refused rather than echoed. When no verified manifest is available the node refuses to start, before it binds a listener. A node without an identity must not serve, and there is no default worth inventing: an empty identity would be a claim about the network, made up by the process that is supposed to prove it. Receive transitions were refused outright at submission, which killed the receive flow even though the domain logic for it exists. Submission now admits `kind == "receive"` and records the job like mint and send, with the §7.5 presence rules enforced at the wire edge — missing `fold_coin_ids`, or `input_coins` / `output_templates` present where the kind forbids them, are `400 malformed_request`. The dispatcher side is deliberately *not* finished here. Executing §2.3.3 needs `ReceivedCoinSlot` reconstituted from `fold_coin_ids`, the private index and the live nullifier log — a `CoinProof` carries neither `pos_create` nor the NAV paths. Until that exists the job path fails terminally rather than being skipped in silence, so a receive job that cannot run says so instead of disappearing. `bootstrap_manifest_from_verified` takes a field struct rather than eight positional arguments. The decoupling from the verification type is the point — the projection must not depend on its layout — and a named field bag keeps that while making the call site readable. * feat: a tool that produces the manifest the node now demands Requiring a verified §4.3 BootstrapManifest at startup was correct — a node without an identity must not serve, and an empty identity would be a claim about the network invented by the process meant to prove it. But nothing in the tree could produce such a manifest: no artifact, no generator, no CLI, and `compose.yaml` never set the path. The local stack could not start, and no test showed it, because tests build the store directly. `gen_bootstrap_manifest` closes that. It writes a real BMF1 artifact in the same encoding and signature domain the verification path expects, reusing the shared codec rather than restating it. The secret comes from an env var or a file, never from argv, and is never printed or written alongside the output. If the public key derived from the secret does not match the supplied `bootstrap_pubkey`, it aborts before writing a single byte — refusing to produce an artifact the verifier would reject is more useful than producing one and discovering it at boot. `compose.yaml` wires the path through, and `docs/local-stack.md` gains the ordered walkthrough: provide the operator key material, set the pubkey, generate, point the node at it, start. Five places in that document described the missing loader as a permanent limitation; those are now the procedure instead. Verified against the tool itself: a deliberately wrong pubkey aborts and leaves no file; the correct one writes 186 bytes opening with the BMF1 magic, the regtest tag and the v1 protocol version. Starting the full stack end to end still needs Postgres and bitcoind and is not covered here. * feat: make Publish real — policy, durable queue, aggregation, inscription `Publish` was the last big pretence in the kernel: a hard-wired `AcceptFeeLess` with a sixty-second promise, and behind it nothing. A caller got "accepted" and the transition never reached Bitcoin — worse than a refusal, because the wallet had no reason to retry. The decision now follows the request and the configuration. A node whose `kernel_parts` does not include the publisher declines; one that does requires `ZKCOINS_PUBLISH_BATCH_ETA_SECS` to be configured — there is no invented deadline — and only then checks the member's signature and anchor and enqueues it durably. Acceptance *is* the durable enqueue: a restart finds open hand-offs via `list_resumable` and resumes them, so an accepted member can no longer evaporate with the process. The drain path half-aggregates queued members per §3.3 — arithmetic over collected BIP-340 signatures, no circuit, no secret keys — into one `AggregateStateNullifierV3` and inscribes it per §3.5, walking each member through constructed → commit-broadcast → reveal-broadcast to a terminal state. Member status is classified from actual chain observation (§3.10) rather than asserted: `completed` exists only at sufficient confirmations, and a failure on the inscription path is a named terminal state, never a silent skip and never an `accepted`. Where the process ends at a boundary this tree cannot cross without a running bitcoind, it fails terminally and says so. The compose file and the local-stack walkthrough carry the new required variable — a fail-closed requirement without its wiring is how the manifest requirement briefly killed the local stack, and that mistake does not need a second edition. * feat: verify the delivery credential in the kernel, and keep only what delivery needs §7.5 now carries `OutputTemplate.delivery`; this is the kernel side of it. The proto gains the closed oneof (`invoice` | `profile`), and the conversion layer keeps absent and empty distinct, as it already does for `publisher_pubkey`. The presence rule runs at the wire edge, before a job exists: on send and mint, every output that is not a self-output must carry a credential, and self-output is exactly the spec's conjunction — recipient, subject and the persisted account owner decode equal, and the operational bundle is held under that very subject. A node holding a foreign account's bundle does not make that account "self"; a test proves the attempted shortcut fails. The end-to-end witness drives `submit_transition` itself and asserts that a foreign output without a credential produces no job row and leaves the target store untouched. The cryptographic chains run kernel-side before proving, reusing the §4.3 machinery that already existed: for an invoice the three checks in order plus byte-exact equality of recipient, asset and amount with its own output template; for a profile the event chain plus the recipient-address match, with freshness tracked per author against a high-water mark — relay-relative, exactly as the spec now words it, and an older event than the one already seen is refused. The age window takes an injected clock rather than reading the wall clock, following the bootstrap's ManifestClock pattern: the honest fixture had failed simply because time had passed, which is the same flakiness class the Postgres readiness fix closed — a test that is green today and red in a year. An unavailable clock rejects the profile with a named reason; the check is never skipped. After a credential passes, the target store keeps `{ivpk, op_pubkey, relays}` and the deadline. `pk0`, `nk_commit`, `memo` and the signatures are dropped — not persisted, not logged, not quoted in errors — because `pk0` links a recipient to its genesis nullifier on Bitcoin, and a delivery path has no business retaining that. * fix: probe the relay before the pool tests use it Under a parallel full run, `integration_pool_publish_and_query_per_relay _results` hit the window in which the relay container has bound its port but does not yet complete a WebSocket handshake, and failed with "Handshake not finished". Run alone it passes every time — the container is warm by then. That is the same flakiness class the Postgres readiness fix closed: a test whose green depends on who ran before it. The pool's production semantics are untouched — reporting an unreachable relay as `Unreachable` per relay is correct fail-closed behaviour and stays. What was wrong was the tests' readiness assumption. The shared test setup now probes the relay with a real WebSocket connect in a retry loop under a deadline before any test body runs: transient conditions (handshake not finished, refused, reset) back off and retry, exhaustion panics with the attempt count and the last error. Every test of the module that attaches to the same container goes through the same probe, so the fix is not one test wide. Verified against the failure mode: the full suite run twice from cold containers, 1313 tests green both times. * feat: execute receive — reconstitute the slots and run §2.3.3 for real Admission for `kind == "receive"` existed; execution did not. The job path ended in a deliberate terminal failure because nothing could turn the persisted `fold_coin_ids` back into the `ReceivedCoinSlot`s the receive transition needs — a `CoinProof` carries neither `pos_create` nor the accumulator paths, on purpose. Reconstitution now builds each slot from what the node itself holds: the stored `CoinProof` the §4.4 receive path persisted, the coin's creating position from the private index, and the inclusion paths from the live nullifier log of the node's own scan. Any missing ingredient — an unknown coin id, a nullifier not yet `completed`, a duplicate, more than `MAX_RX_COINS` — fails the job terminally with a named reason. Clause 10 demands every folded coin pass; there is no partial success to offer. The dispatcher's receive branch drives the same begin/execute pair the production path owns: shape validation at begin, reconstitution, then `verify_and_begin_receive` through to `awaiting_signature`, with `execute_v1_receive` after the signature — the same phase mechanics as send, because §7.5 gives all three kinds the same handshake. The NotWired terminal is gone entirely. The first version of the end-to-end witness went through `JobStore::create` directly and exercised a sanity path *beside* the dispatcher — green tests over code the production flow never reached, the same gap the publisher wiring had. It now drives `submit_transition` and a real dispatcher tick. Its wall time is the genuine receive circuit build (~6 min measured), so it sits in the heavy `#[ignore]` class with the four prove flows and their `--ignored --release` run; the fast negative and presence tests keep the wiring covered in the default suite. Test fixtures claim the v1 stack mode the way every other v1 persist test does — the stack-separation guard refused them until they did, which is exactly its job. * feat: durable delivery — an outbox backbone and the second SDR phase Delivery held its pending state in process memory: a restart between persisting a transition and delivering it dropped the delivery, the sender discarded the held record the moment an ACK arrived without waiting for the replication receipts §4.2 requires, and nothing ever republished. Crash in the wrong millisecond and a coin was anchored on Bitcoin but never reached its recipient. And the self-delivery record had only a first phase — the second, which §4.5 recovery and multi-device rest on, was unbuilt. **The outbox.** A Postgres-backed outbox (migration 0032) is now the single backbone. Every pending delivery lands there before its first attempt, so the insert is durable with the step that owes it. Each row runs a state machine: pending → published (with attempt count and next-attempt time) → awaiting ACK → awaiting the k receipts → completed. A row completes only when the ACK *and* the receipts are in; before that it is never discarded. The runtime loop that used to poll ACKs now drives due rows with exponential backoff (§4.2, 30s doubling to 1h), and on boot resumes every non-terminal row — the crash point stops mattering, because what the outbox knows it finishes. Terminal failures are named and leave the loop (`failed` + reason); the backoff caps the delay, not the attempt count, so a purely transient target keeps retrying. The Blossom upload receipt is persisted rather than discarded. **SDR phase B.** `SelfDeliveryRecordV1` now has its second phase (migration 0033). Phase A stages the durable material at send time, keyed by the transition nullifier. Phase B is a scanner hook: when the account's own nullifier is a first-occurrence winner inside `size_final` (§3.10 completed), it fills the inclusion block and BIP-113 MTP, seals `serialize(SelfDeliveryRecordV1)` under ZBE, and inserts a `self_delivery` outbox row — so the same drive/resume/backoff machine carries it. Incomplete material fails the record with a named reason rather than skipping the self-delivery in silence. The scanner hook is live in the production scan loop (`run_v1_scan_loop`), reached across the binary/library boundary through the crate's public-façade allowlist, not behind a feature that would drop it from the MVP node. Receipt trust-list and BIP-340 verification against the operator set, and SDR recovery replay, are named follow-ups: until they land the k count admits any well-formed receipt with a distinct holder — a counting property, not yet a security one. * fix: three silent fallbacks that turned a broken value into a plausible one Each of these took an absence or a corruption and quietly produced something that looked fine, which is the failure mode that hides the longest. A job status read from the database that the code did not recognise was mapped to `Failed` — so a schema drift or a newer status would silently mark every affected job as failed, indistinguishable from a real failure. It is now a decode error propagated with `?`, exactly as `Job::from_row` already treats an unparseable row; the loader returns the error instead of inventing a terminal state. `unix_now()` returned `0` when the host clock sat before the epoch, so challenge-expiry and grant-window checks would compare against a meaningless timestamp. It now returns a result, and the ten kernel session and challenge paths that read it fail closed with a named "Kernel clock unavailable" — a broken clock stops the operation rather than dating it to 1970. (The helper returns the domain error rather than `Result`; a tiny Ok beside a large `tonic::Status` is the `result_large_err` shape the file already avoids, so the call sites map with `map_domain_err`.) A completed job replayed with no recorded `response_status`, or with a stored value that is not a valid HTTP status, was served as `200 OK` — a missing status became success. Both now return `500 internal_error`: an absent or corrupt status is an internal inconsistency, not a result to hand back as if the request had gone through. * ci: measure coverage honestly — a real floor, not a 100% fiction The coverage gate reported "100% lines + functions" by removing from the measurement exactly the production modules that were least tested: `publisher.rs`, `runtime.rs`, `flow.rs`, `job_dispatcher.rs`, the scanners, and all of `shared/src`. A green gate meant nothing about those files, and a log entry once claimed this was fixed when the fix lived only in an uncommitted worktree. Measured on the current tree, with only the defensible exclusions, the node + shared surface is 77.28% lines and 77.82% functions. That is the floor now: `--fail-under-lines 77 --fail-under-functions 77`, and the `--ignore-filename-regex` is trimmed to test infrastructure (`*_tests.rs`, `test_db.rs`, `bin/`), crate entrypoints (`main.rs`, `lib.rs`), and the Plonky2 circuit packages. The illegitimate exclusions are gone: publisher, runtime, flow, job_dispatcher, the scanners and shared are all measured. The circuit packages are the one non-trivial exclusion, and the baseline says why: their correctness is secured by the §1.7.9 digest generator, the prove tests, and the D-05 differential test against the reference implementation — line coverage over gate tables would drown the floor in structurally un-executable paths without adding assurance. `.github/coverage-baseline.md` records the rules, the measured floor, the per-file gap list, and the standing rule that the floor does not sink. README and CONTRIBUTING drop the 100% claim for the measured floor. The workflow stays paused; moving this gate from `ci:full`-only to every non-draft PR is noted in the baseline as CI-endgame work, so the un-pause cannot quietly ship the old fiction. * build: install protoc in the node image, and add the local-e2e harness The node image would not build: `kernel-proto/build.rs` compiles the `kernel.v1` gRPC contract with prost, which needs `protoc` at build time, and the builder stage never installed it. Local `cargo build` (protoc already on the developer's PATH) and the paused CI both hid this — only a clean-base image build surfaced it. The builder now installs the same pinned `protobuf-compiler` the api image uses. `deploy/local-e2e/` is the entry point the stack lacked: env template, an ordered `up.sh` that generates the bootstrap manifest and waits on each service's healthcheck before the next, a `journey` that runs the mandate's §3 A-to-Z assertions, and `down.sh`. It reuses the existing regtest `compose.yaml` rather than a second stack definition. The journey is honest about what runs for real and what does not yet. The default run hard-asserts steps 1 and 2 — `GET /v1/info` equals the pinned regtest digests and bounds, and Alice's mint drives a real Plonky2 prove to `completed`, inscribes its nullifier, reaches §3.10 `completed` after six mined blocks, and lands the expected balance. The fee-less send's `fee_address` rejection is asserted; the positive send/receive path, the token-standard-2 second asset, and the reorg/recovery/portability/attestation/grant controls (§3 steps 3–11) are TODO skeletons that fail with a named error rather than passing silently — the delivery loop they need is real Nostr/Blossom transport, built but not yet driven from this harness. No mocks on the protocol path; a skeleton says so instead of pretending. * build: harden the local-e2e harness from the first real boot Running the stack for the first time turned up three things a written harness could not have predicted. The node builds the §1.7.9 circuits (C and C_balance) at boot before it serves `/health` — cold, that is multiple minutes of "Adding blinding terms", not a hung process. The node service's healthcheck now carries a `start_period` of 1200s with 30 retries so a slow cold build does not burn probes into `unhealthy`, and `up.sh` waits 20 minutes with a progress line that says the circuit build is why. The circuit build is memory-heavy: the node container was OOM-killed (exit 137, OOMKilled) in a ~15.6 GiB Docker VM. The README gains a Memory prerequisite — assign the Docker VM at least 24 GiB, because 15.6 demonstrably is not enough — and `up.sh` reads `docker info` and warns (non-fatally, the exact figure depends on the build) when the VM looks smaller than ~20 GiB. And the env file derived its paths from `${BASH_SOURCE[0]}`: sourced under zsh, that is unset, so `COMPOSE_FILE` pointed a level too high and compose could not find `compose.yaml`. The shebang protects execution but not sourcing, so the env file now refuses loudly under any non-bash shell with the exact bash invocation to use, rather than deriving a silent wrong path. * ci: switch the hosted runners back on, and gate the prove path Hosted CI was paused for the whole v1 rebuild so the self-hosted pool was not spent on a tree known to be mid-flight. The rebuild is done and verified locally, so this restores it — the un-pause is the deletion the paused block was written to be: the PAUSED note goes, and the `pull_request:` trigger that sat commented out verbatim comes back. `workflow_dispatch` stays for a hand-started run. Two things move past where they were parked. The coverage gate now runs on every non-draft PR instead of only under the `ci:full` label — the measured 77% floor is the standing check, not an opt-in, and the baseline already recorded that this belongs to the un-pause. And the prove path, which the gate never exercised, gets two steps on the heavy self-hosted job: the `zkcoins-prover-plonky2` release suite, and the four `#[ignore]` flows in node + shared run under `--run-ignored ignored-only` (begin_receive / begin_send / verify_incoming / prover_bridge_real_end_to_end). Those are the tests that ran nowhere; they run here now. A representative of the set was verified locally — a real multi-input send prove, 290s, green — before wiring it in. The heavy job's timeout goes to 180 minutes to hold them. * fix: fail-closed on mainnet for provisional inclusion/MTP, plus review follow-ups A review of the Phase-B self-delivery path surfaced a real risk: the scanner hook sealed a SelfDeliveryRecordV1 from a provisional Inclusion/MTP stand-in (chain-tip hash + wall-clock seconds) on every network. That stand-in is fine for regtest and testnet while first- occurrence inclusion and BIP-113 median-time-past over bitcoind are still being wired, but on mainnet it would write a non-normative record. The provisional builder is now `provisional_inclusion_mtp_for_network`, which refuses on mainnet with a named token (`PROVISIONAL_MTP_MAINNET_REFUSED`) and an operator-readable reason. On refusal the finalizer leaves the Phase-A rows open for a future real-MTP path rather than marking them failed, so no recoverable material is destroyed. The polling-guard CI step was checking deleted Esplora WS scanner files, so the live scan loop in `main.rs` was never covered — the guard was green over code it no longer looked at. It now greps `main.rs` and `publisher.rs`, and each grandfathered idle-backoff sleep there carries a same-line `scanner-polling-ok:` marker naming why it is not a tip-advance poll. The awaiting-receipts outbox rows had no timeout path: a hand-off that never gathered its k receipts stayed pending forever. `fail_stale_ awaiting_receipts` now moves them to a named failed state past the timeout instead of blocking silently. Doc and test honesty: the kernel-RPC mapping no longer claims RPCs are fully wired where only the transport boundary is; the RPC tests now distinguish a mapped-but-malformed request (InvalidArgument / Internal) from a genuine feature-gated Unimplemented, so a green test no longer implies a reachable production path; and CONTRIBUTING documents the provisional-MTP mainnet refusal. * fix: only fail delivery rows that truly missed their receipts; tighten the timeout sweep A review of the awaiting-receipts timeout found it could mark a row `failed` even when the required receipts had in fact arrived: the sweep keyed off the ACK age alone. It now locks each past-deadline `awaiting_receipts` row `FOR UPDATE`, counts the durable receipts under that lock, and completes the row when the count already meets `replication_k` — only a row still short of k after the deadline becomes `failed`, with the named reason. The lock serialises against `store_receipt`, so the k-th receipt and the timeout can no longer race to opposite terminal states. The receipt-count helper is marked `#[cfg(test)]`, since production counts inline within that same transaction; the doc that claimed otherwise is corrected. Errors from the sweep are now surfaced with a named log instead of being swallowed. The mainnet provisional-MTP refusal is now covered through the production finalizer (not just the helper): a mainnet adapter seals no SDR and leaves the Phase-A rows open. CONTRIBUTING documents the mainnet feature restriction and fixes the Docker example and CI-gate description; the kernel-RPC mapping doc is made internally consistent. * style: rustfmt the outbox timeout and SDR mainnet-guard changes * ci: install protoc before the Rust steps (kernel-proto build.rs needs it) * test: race-test the receipt/timeout boundary; make the quick-start actually start Follow-up review asked for the concurrency and mainnet-guard properties to be proven, not just asserted on helpers. The receipt/timeout boundary now has a test that races the k-th receipt against the timeout sweep and shows the row completes rather than fails, and the mainnet SDR test recognises terminal self-delivery outbox rows. The CONTRIBUTING quick-start and the local-e2e script are corrected so a fresh checkout can actually start, with the real prerequisites named. * ci: target the zkcoins-node runner label so the heavy test gate can actually schedule * ci: install protoc on the self-hosted runner too (heavy test gate builds kernel-proto) * test: refresh the nav_rand compile-fail snapshot for the pinned toolchain The `ReceiveRequest`-has-no-`nav_rand` trybuild snapshot still carried the older rustc note ("available fields are: …"); the pinned nightly now emits "all struct fields are already assigned" for the same case. The invariant is unchanged — the code still fails to compile with E0560, so `nav_rand` stays unobtainable by construction — only the compiler's secondary note wording is refreshed to match the pin. This surfaced now because the heavy test gate had never been able to reach this step before (runner label + protoc issues fixed separately). * fix: remove the drop/receipt subsystem — a node never deletes stored data (Data Permanence) Satisfies Data Permanence (Requirement 12): a node never deletes, drops, or expires data it has received. The delivery outbox loses its entire awaiting-receipts / ReplicaReceiptV1 / replication-factor-k / drop-after-k machinery (fail_stale_awaiting_receipts, the receipts table, replication_k, the drop conditions) — over 900 lines removed from db_outbox.rs alone. Reliable §4.2 delivery is untouched: pending → awaiting_ack → completed on a valid ACK, with republish backoff; the sender simply keeps its own copy forever instead of dropping it after k receipts. Migration 0032 drops the receipts table and replication_k from its definition (unshipped), and the status CHECK no longer admits awaiting_receipts. The node's own Blossom store loses its DELETE handler and becomes append-only. Tests assert the removed status/column/table are gone and that no delete or drop path remains. * fix: never physically delete derived state either — archive-and-recompute via state epoch Extends Data Permanence (Requirement 12) to reconstructable derived state: no production code path physically deletes a stored row anywhere. The self-heal proof-dependent reset stops wiping the state tables with DELETE and instead bumps a `derived_state_epoch` (migration 0034 adds `derived_state_epoch_meta` and a `state_epoch` column to every derived table): the recompute writes rows under the new epoch, reads are scoped to the current epoch, and every prior-epoch row is retained in the store, never deleted — only excluded from the canonical view. A reorg was already recompute-based (`accumulator::reorg_replay` re-folds positions canonically and keeps orphaned entries), so no deletion path existed there. Every remaining production `DELETE FROM` / `TRUNCATE` is gone; only test-DB resets still clear rows. Multi-epoch coexistence relaxes a few cross-table foreign keys (an old-epoch row can reference an old-epoch parent), which the epoch scoping replaces logically. Tests assert the pre-reset state survives in the store while the canonical view shows the recomputed state, and the self-heal error-propagation test now injects its failure on the epoch table the reset actually writes. * feat(v1): wire the mint/send prove paths and make finalised balances readable Complete the v1 migration in the job dispatcher: process_mint and process_send_initial now build the native StateEngine MintRequest/SendRequest and drive begin_v1_mint/begin_v1_send through the same finalise handshake as receive, instead of the legacy DTO path (which only ever refused under the v1 shadow mode). Carry the spec-mandated issuance creator_pubkey (Pk0) across the proto, kernel, API and SDK; a genesis mint resolves current_pubkey from it, a remint from the account's rotated engine state. Enforce the operational -bundle authorization gate on send, matching mint and receive. Make a finalised transition's account state readable: mirror the engine's post-persist AccountState into the process-local index that GetAccountState serves (unconditionally, right after durable persist, for mint/send/receive), hydrate that index from the engine at boot for restart-safety, and fail closed on poisoning. Self-delivery outbox rows now complete on durable publish rather than waiting for an ACK that self-delivery never receives. Remove the now-dead legacy mint/send flow and its helpers, and add a .dockerignore so the build context no longer ships the target directory. * feat(v1): add the genesis-receive Pk0 carrier and dedup self-delivery per transition A recipient's first transition is a genesis receive whose InitialProof binds owner == H(Pk0 ‖ nk_commit); Pk0 is wallet-only and rotates per transition, so it must travel on the wire (the identical reason a mint carries creator_pubkey). Thread the new genesis_pubkey field proto→kernel→dispatcher and resolve the genesis current_pubkey from it, with the engine independently re-checking the owner binding fail-closed. Scope the self-delivery outbox uniqueness by transition_pk (migration 0035) so each transition's own record is kept. * feat(v1): complete token-standard-2 mint with non-owner emission Wire the token-standard-2 (capped-supply) mint path end-to-end so an issuer can emit newly minted units to a non-owner recipient (spec §6.5 clause g), proven live through the local-e2e journey (stage 2b: a third account mints a capped EUR-Demo asset that a first account then receives, ending on a verified two-asset balance). - state_engine::begin_mint: add MintRequest.output_templates; require token-standard-2 mints to carry explicit non-owner emission outputs and token-standard-1 mints exactly one self-addressed output. Validate the owner binding before the output-shape checks so a genesis-owner mismatch reports its own error rather than a spurious output-shape error. - job_dispatcher: parse and thread output_templates through the mint job. - local-e2e: list the third account's operational op_pubkey in the Blossom upload allow-list so a non-owner emission's mesh delivery is accepted. - tests: carry output_templates in the mint fixtures; extend the prover public-surface allow-list for the new field. * test(v1): refresh the sig-agg vector header to match its generator The committed generated_sig_agg_vectors.txt still carried the pre-correction header ("pinned by the spec / earlier generators"). The generator was later made honest about the V.5 provenance ("reference-implementation output; proposed for V.5 in PR #124 draft", generated_sig_agg_vectors_test.rs) without regenerating the file, leaving the verify gate red. Regenerate so the artifact matches its generator: only the header comment changes — every V.5 signature, V.6 s_agg and V.8 fixture value is byte-identical. * feat(v1): attestation and view-grant disclosure controls with trustless verifier cache Complete the two v1 disclosure controls (Requirements 9(b) and 9(c)) end-to-end, proven live through the local-e2e journey (stages 10 and 11). Attestation (§5.7, Req 9(b)): - attest_verify.rs: an independent, trustless BalanceAttestationV1 verifier — decode (exact inverse of the serializer), verify the C_balance proof, and bind every one of the proof's 60 public inputs to the decoded header before the §5.7 host checks, so a valid proof can never be paired with a mismatched header. - Producer wiring that production never populated: derive last_nullifier_pos from the NfLog when the account cache is empty; resolve the anchor reveal_txid from the durable inscription catalog (not only the transient pending-publish); and record scanned per-height block hashes (block_log had no production writer). - verifier_cache.rs: a digest-pinned verifier-data cache. The node serializes the C_balance verifier data once at boot; verify_attestation loads it (megabytes, no ~100 GiB circuit rebuild) and, before trusting it, recomputes the circuit digest from the loaded data and requires it to equal both the file's stored digest and the pinned digest — so a forged cache carrying the pinned digest beside a foreign circuit body is rejected. Ships the verify_attestation binary and the ZKCOINS_VERIFIER_CACHE_DIR volume path. View grants (§5.1/§5.2, Req 9(c)): - Self-delivered coins (own mint output, send change, receive fold) were never disclosable: only the receive path wrote records, so a scoped pull returned zero records for an account's own history. Record a self_delivery entry (durable v1_self_delivery_index plus the in-memory index mirror) at SDR-phase-A finalise, retaining the canonical CoinProof bytes before they are sealed; idempotent per (subject, coin_id). local-e2e: journey stages 10 (produce -> independent verify -> tamper-reject) and 11 (issue USD-scoped grant -> in-scope pull -> out-of-scope EUR refused 403). * feat(v1): secondary-node boot mode loading a verified C_balance cache Enable a second node instance to boot against a SHARED verifier-cache volume without rebuilding the ~100 GiB C_balance circuit, so a multi-node local stack does not run two concurrent circuit builds (OOM on a 96 GiB VM). Foundation for the reorg/recovery/portability journey controls. ZKCOINS_VERIFIER_CACHE_ROLE (primary|secondary): - primary (default): unchanged — build both circuits, verify their digests against the §3.6 pins, write the cache. - secondary: load_balance_verifier_cache_checked (recomputes C_balance's circuit digest from the loaded constants and requires it to equal the pin — the same cryptographic guarantee as a rebuild), then mark the balance identity satisfied from that verified digest. Builds only the small C circuit lazily at first prove; never builds C_balance. Install the §3.6 circuit pins early — before the ledger load and before the role branch, for both roles — so the ProverBridge identity gate is armed before any circuit build (a ledger-load prev-proof bind, or first prove) and every build is checked against the pin. ensure_proving_identity now builds only the circuit whose identity flag is unset, keeping the fail-closed invariant: no proof proceeds unless both C and C_balance are pin-verified (by a local build or by the cache's digest-recompute-vs-pin). require_live_identity is unchanged for the primary boot. Also fix a latent guard: install_network_pins compared OnceLock::set's returned value (the caller's own pins) instead of the stored pins, so a divergent second install was silently accepted; it now reads the stored value and refuses a genuine pin swap. * feat(local-e2e): second node instance (node2/api2/postgres2) for multi-node journey Add a full second node to the local-e2e stack so the reorg/recovery/portability journey controls can target a real second node. node2 boots in secondary verifier-cache mode: it loads the shared cache node1 writes (verifier_cache_shared volume) and — proven live — comes up in ~6s using ~26 MiB, never building the ~100 GiB C_balance circuit, so the stack never runs two concurrent circuit builds. - compose.yaml: node1 mounts the shared cache and is pinned ZKCOINS_VERIFIER_CACHE_ROLE: primary; new postgres2 (own volume, no host port), node2 (ports 4243/50052, own DB, own funded wallet, depends_on node1 healthy so the shared cache exists before it boots, ROLE: secondary), api2 (port 8081, dials node2). New volumes node2_data, postgres2_data, api2_blossom_data, verifier_cache_shared. - up.sh: fund node2's own bitcoind wallet and restart node2 after node1, never concurrent restarts; fail-closed on a zero balance exactly like node1; wait node2/api2 healthy. - env.example.sh: PUBLISHER_KEY_2, ZKCOINS_V1_BITCOIND_WALLET_2, ZKCOINS_BLOSSOM_URL_2, ZKCOINS_API_URL_2, ZKCOINS_NODE_URL_2. * feat(local-e2e): journey stage 7 — reorg convergence control (N-09) Drive a shallow regtest reorg on the shared bitcoind (invalidate the last 3 blocks, mine a strictly longer 6-block branch) and assert the two independent nodes converge: node1 (which processed the reorg incrementally) and node2 (a fresh from-genesis scanner) reach the same accumulator (size, root) at the same stabilised tip. waitNodesConverged polls both nodes for tip equality + stability rather than an externally-computed exact hash (which is fragile under regtest equal-height forks and scan lag). Proven live: both nodes converged to size 3, identical root, tip_height 244. Follow-up hardening: the current reorg spans an already-final region; to fully exercise "spanning a pending nullifier" (§ mandate V.9 N-09) a fresh pre-finality send should be issued immediately before the reorg. Tracked for the final pass. * v1: durable verifier cache + §4.5 SDR-replay recovery, reorg-safe canonical inclusion/MTP - Persistent digest-pinned C/C_balance verifier cache: a secondary node loads the pinned verifier data instead of rebuilding the circuit at boot. - §4.2 SelfDeliveryRecordV1 two-phase self-delivery and §4.5 recovery replay with the full soundness checks (owner/nk/send_counter binding, equivocation, ordering). - Inclusion block + BIP-113 median-time-past resolved canonically via bitcoind get_block_hash at a final height (robust against same-height flip-flop reorgs) and stored in block_log byte order so §4.5 check (v) matches on an honest node. - Recovery campaign retries a bounded window to survive asynchronous relay propagation. - Recovered account head is registered in the in-memory private index so the capability-gated pull endpoint can serve it after recovery. - Full local journey (mint -> send -> receive -> reorg convergence -> recovery) green on the two-node stack; recovered balance equals the source node. * v1 recovery: persistent multi-entrust driver + already-recovered skip; retry/private-index tests; stage-9 portability journey - Recovery driver is now a persistent background service (outer loop, 20s watch) that recovers accounts entrusted at any time, not just the first one — fixes portability / multi-account: a second, later-entrusted subject is now reconstructed. - Re-running passes skip subjects already recovered on this node (checked via the same private-index the pull endpoint reads), so they are never re-scanned/re-installed while still counting as satisfied for the restored decision. - Unit tests: the retry predicate should_retry_recovery (5 cases) and the recovered-head private-index registration (servable via get_account_state). - Journey stage 9 (Requirement 10 portability): repoint Alice to the second node, assert balances identical there (green), then a send from the repointed node. The send exposes a separate secondary-node proving limitation (a verifier-cache-only node cannot yet build a self-consistent prover on demand) tracked as follow-up. * test(shared): full coverage for spec_v1 error + datastructures - error.rs: unit-test every SpecError variant Display (96/96) + Error/source + derives → 100% line/function - datastructures.rs: construct/roundtrip Address/AccountState/Coin/CoinTemplate/ProofData/SpendRecord incl. BigArray64 serde, valid + invariant-violation paths → ~97% (only an unreachable-with-bincode serde Visitor arm remains) * test(accumulator): §3.9 Reorg-Finality-Matrix — Tiefe 1-7 deterministisch Reorg-Tiefe 1-5 toleriert (finality_broken=false, displaced=0), 6 verdrängt eine finale Position (displaced=1), 7 verdrängt zwei (displaced=2). Plus content-preserving-Deep-Reorg (Tiefe 6, gleiche pk/r → kein Break: Semantik ist inhalts-, nicht tiefenbasiert), shrink-with-missing-final-position, size_final-Grenzen (tip<5, exakt 6 Confs, Höhen-Lücken), empty/identical/ reorder-nonfinal-Streams, unsortierter-Input-sortiert-intern, und Fold-Error-Propagation bei doppelter chain_pos (fail-loud, kein Swallow). 15 neue Tests, nur Testmodul, Produktionslogik unverändert. * test(shared): Coverage 96→98% — spec_v1 + commitment Error-/Edge-Pfade Gezielte Tests für Error-Arme, Roundtrip-Encodings und Grenzbranches in accumulator, bootstrap_manifest, bundle, coinhist, datastructures, encoding, hashes, network_params, nflog, nflog_boundary, note_encryption, serialize, trees, commitment. error/network_params/trees/datastructures jetzt 100% Lines. Nur Testmodule, Produktionslogik unverändert. Zwei Testfixes: Pattern-Binding- Shadowing (accumulator) und echt-falscher Top-Pivot statt No-Op (nflog_boundary). * feat(prover): host-weiter Prover-Lifecycle — Lease == Circuit-Residenz, drop-when-idle Der ~90-GiB-C-Prover wurde prozessweit im OnceLock ewig gehalten → zwei provende Nodes passten nicht auf 128 GiB. Umbau auf droppbare Arc-Slots + host-weite exklusive flock-Proving-Lease (ZKCOINS_PROVER_LEASE_PATH auf geteiltem external Volume): die Lease-Lebensdauer ist an die tatsächliche Circuit-Residenz gekoppelt (Arc::strong_count), die flock fällt erst, wenn der letzte Arc weg ist UND Idle-TTL abgelaufen. Jeder Build-Pfad (prove, Boot-Self-Heal, Digest, Gate-Count) laeuft unter der Lease → max. EIN C-Prover host-weit. Reaper selbstheilend (catch_unwind je Tick), balance_circuit prueft eigenen Slot zuerst (kein C-Rebuild bei C_balance-Cache-Hit), fail-closed bei fehlendem Lease-Pfad, Pin-Check §1.7.9 bei jedem Neubau. Schaltet Stage-9-Send, Multi-Network-Dual-Stack und 3-Node auf 128 GiB frei. 10 Lease-Unit-Tests (strong_count-Eviction, external-ref-blockiert-Freigabe, flock-Gegenseitigkeit, Panic-Recovery, fail-closed). Zweifach codex-reviewt (INV-1 haelt). Live-2-Node-Integration folgt. * chore(local-e2e): ZKCOINS_PROVER_IDLE_TTL_SECS=180 für beide Nodes Idle-TTL für den lokalen 2-Node-Journey erhöht (Default 30s), damit node1 seinen C-Prover über aufeinanderfolgende Prove-Stages hält statt zwischen Stages zu evicten+neu bauen; Stage-9-Handoff an node2 bleibt auf ≤180s begrenzt. * fix(v1): Blossom-Auth-Timestamp am Upload-Boundary frisch lesen (Stage-9-Send 401) Die kind-24242-Blossom-Auth-Timestamps wurden beim Finalise-Hook-Eintritt erfasst — also vor dem mehrminuetigen Proving. Seit node2 dank Prover-Lifecycle selbst C baut (~5min), ueberschritt die Proving-Dauer das 300s-Replay-Fenster, sodass Blossom das abgelaufene Auth-Event korrekt mit HTTP 401 ablehnte. fresh_blossom_auth_timestamps() liest now() jetzt unmittelbar vor jedem PUT; auth_expiration-Vorabberechnung aus dem finalise/outbox/SDR-Pfad entfernt. Fail-closed bei Clock-vor-Unix-Epoch (kein stiller 0-Fallback). 2 wiremock-Tests. * test(shared): letzte Meile — nflog/note_encryption/nflog_boundary/bootstrap Rest-Branches nflog.rs jetzt 100% Lines (m==0&&n>0 false-Zweig), note_encryption base64url rem==0-Pfad, nflog_boundary m==n&&b==true-Basisfall (subproof_honest), bootstrap matches!-Region-Attribution. Nur Testmodule. Verbleibende ~40 Zeilen sind nachweislich unerreichbare defensive Pfade (dokumentiert in coverage-baseline). * docs(coverage): shared-Crate Rest-Zeilen als nachweislich unerreichbar dokumentiert shared spec_v1/commitment auf ~99% Lines (5 Dateien 100%); der Rest sind defensive/unmoegliche-Zustands-Pfade (72PB-Allok, 2^-128-Preimage, Err(_) nach garantiert-32-Byte-Konversion, pre-validierte bundle-Arme, llvm-cov Region- Artefakte). Baseline-Regel 3: dokumentiert statt still ignoriert. * test(node): v1/mode.rs Env-/Boot-Pin-Parsing vollständig getestet 42 Tests für v1_boot_pins_from_env, v1_shadow_mode_from_env, verifier_cache_role_from_env, parse_hex_32, network_label, validate_v1_boot_pins — jeder Fehler-/Env-Parsing-Zweig (unset/blank/ungueltig/non-UTF8/Grenzwerte).

Nur Testmodule. 1231 node-Tests grün (nextest, process-isoliert). Rest-Zeilen = dokumentierte Unerreichbare (Guards) bzw. PgPool-/Scanner-abhängige Integrationspfade. * feat(coverage): Integration-Coverage-Pipeline — Journey unter llvm-cov Coverage-gated SIGTERM/SIGINT-Flush-Handler (__llvm_profile_write_file, hinter cfg(all(feature=coverage-flush, coverage_nightly)) — null Produktionsverhalten sonst), instrumentierter Docker-Build (ARG COVERAGE), compose.coverage.yaml, collect-Skript (Journey 1→9 unter Coverage → profraw mergen → mit Unit-lcov kombinieren). Deckt die nur-über-den-Live-Stack erreichbaren Integrationspfade. Beide Builds kompilieren. * coverage: Circuit-Crates von Instrumentierung ausnehmen (crate-level coverage(off)) Der instrumentierte node-Build instrumentierte auch den ~1.38M-Gate-plonky2-Prover → C-Konstruktion zu langsam fuer den Integration-Coverage-Journey-Lauf (node1-Boot ueberschritt den Health-Timeout). #![cfg_attr(coverage_nightly, coverage(off))] auf script-plonky2 + program-plonky2 nimmt die (ohnehin von der Coverage-Floor ausgenommenen) Circuit-Crates aus der Instrumentierung → normal-schneller Prover, nur node-Integrationscode wird gezaehlt. Null Produktionswirkung (cfg-gated). * coverage: Instrumentierung via RUSTC_WORKSPACE_WRAPPER auf Workspace-Crates beschraenken Globales RUSTFLAGS=-C instrument-coverage instrumentierte auch das externe plonky2-Crate (schwere zk-Mathematik) → C-Konstruktion zu langsam → node1-Health-Timeout im Coverage-Lauf. RUSTC_WORKSPACE_WRAPPER wird von cargo NUR fuer Workspace-Member aufgerufen, nicht fuer Registry-Deps wie plonky2 → Prover normal-schnell, nur node+shared instrumentiert. * docs(coverage): node unit+integration = 83.09% (Journey unter llvm-cov gemessen) Integration-Coverage-Pipeline funktioniert: Journey 1→9 unter Instrumentierung (workspace-only via RUSTC_WORKSPACE_WRAPPER, plonky2 uninstrumentiert+schnell) deckt die nur-live erreichbaren Integrationspfade; kombiniert mit Unit-Tests springt node-src 76.3→83.09%. Reproduktion + Weg zu 100% (Fault-Injection + weitere Unit-Dateien) dokumentiert. * test(node): sdr.rs §4.5 SDR-Replay — 49 neue Tests (63 total) Phase-A-Staging + Phase-B-Finalise (stage_phase_a, try_finalize_one_from_snapshot, finalize_due_phase_b_with_mtp), publish_sdr_outbox_row inkl. aller Fehler-/fail-closed-Zweige (kind-mismatch, Material-Decode, Hex-Feld-Kurzlaengen, Content-Address-Mismatch, Blossom-Upload- Fehler via wiremock, Relay-Ablehnung), pure Hex-Parser (parse_hex32_field/parse_hex_vec, output_ref_from_built). Integration-only Pfade (bitcoind-RPC, echter Blossom+Relay-Erfolg) bewusst ausgelassen + dokumentiert. * test(node): db_decrypt_index.rs — 12 Tests (neues Testmodul, vorher 0) DecryptVerificationStatus-Roundtrip, decrypt_record_id-Determinismus, to_indexed_record-Feldmapping, ensure_row_shape/exact32/into_row-Fehlerzweige, insert_verified_coin_proof + alle 3 UNIQUE-Constraints isoliert (already-present ohne Ueberschreiben), mark_acked-Idempotenz, get_by_*/list_by_subject Present/Missing, occurred_at-Ueberlauf fail-closed vor DB-Write. Reine SQL/Pure-Datei, keine Integration-only-Pfade. * docs(coverage): node kombiniert 83.09→84.18% (Welle 2: sdr 93%, db_decrypt_index 99.8%) Frische Vollmessung 1606 Tests alle gruen; node-src Unit 77.53%, kombiniert (Unit∪Integration) 84.18% (41456/49249). 4-Schichten-Weg zu 100% dokumentiert (unit-testbar / Fault-Injection / Journey-Erweiterung flow.rs 18% + attest_verify 39% / coverage(off) unreachable). * test(node): self_heal_tests.rs +2 Fehlerzweig-Tests heal_v1_propagates_error_from_reset_tx (reset-tx-Fehler wird propagiert), heal_legacy_reset_refuses_missing_stack_mode_marker (fail-closed ohne Claim). * fix(node): validate_send_request meldet fehlenden Timestamp korrekt + flow.rs Coverage validate_send_request buendelte signature.is_none()||timestamp.is_none() zu 'Missing signature' entgegen dem dokumentierten Vertrag (router.rs: getrennte 'Missing signature'/'Missing timestamp').

Exakte AttestError-Varianten. Scanner-gebundene verify-Pfade integration-only. * docs(coverage): node kombiniert 84.68→85.35% (Welle 4: attest 88%, profile 89.5%, recovery §4.5); inline-Testmodul-Mess-Artefakt dokumentiert * coverage: inline Testmodule via coverage(off) aus der Messung nehmen (ehrliche Produktiv-Coverage) 46 inline #[cfg(test)] mod tests tragen jetzt #[cfg_attr(coverage_nightly, coverage(off))] (wie shared/script/program). Misst echte Produktiv-Coverage statt Testcode. Ehrliche node-src-Zahl: kombiniert 78.63% (24257/30848) — die vorherigen 85% zaehlten Testcode mit (die Testmodule sind ~95% covered und blaehten auf). Rest dominiert von integration-only Produktivcode (Scanner/bitcoind/async/ Blossom/Prover ohne Test-Hook); Korrektheit durch Journey+Reorg+fail-closed gedeckt. 1721 Tests gruen. * test(e2e): Fault-Injection-Stages fuer die Integration-Fehlerzweige (hinter Flag) journey.mjs: bitcoind-Ausfall + postgres-Ausfall als Fault-Stages (Fault -> node meldet fail-closed not-ready -> Stack wiederherstellen -> Erholung verifizieren), hinter ZKCOINS_JOURNEY_FAULTS=1 (Default- Pfad byte-unveraendert, node --check gruen). collect-integration-coverage.sh setzt das Flag. Trifft die Scanner/bitcoind- + DB-Fehler-/fail-closed-Zweige im Live-Node, die der Happy-Path nie erreicht. Live-Lauf reproduzierbar, aber RAM-blockiert (node-C-Build ~82 GiB Peak, aktuell 44 GiB frei) — braucht frischen Boot; Syntax+Signaturen verifiziert, Live-Fault-Verhalten noch nicht end-to-end gefahren. * fix(e2e): collect-integration-coverage wiped stale volumes vor dem Lauf Ohne Wipe schlug Stage 2 mit KeyBindingRefusalError fehl (stale account state aus frueherem Lauf, sendCounter>0). down -v vor up.sh macht jeden Coverage-Lauf reproduzierbar frisch. * fix(e2e): bounded Fetch-Retry in journey httpJson gegen transiente Verbindungsfehler Ein einzelner transienter Verbindungsfehler (fetch failed unter RAM-Druck des instrumentierten Coverage-Stacks) brach bisher die ganze Journey ab. httpJson wiederholt den fetch jetzt bounded (max. 3 Versuche, Backoff 500/1500ms via sleep, 15s AbortController-Timeout pro Versuch). Retry ausschliesslich bei geworfenem fetch (keine Response erhalten) - eine erhaltene HTTP-Antwort (auch 4xx/5xx) wird nie wiederholt, daher keine Doppel-Submission nicht-idempotenter POSTs. Nach 3 Fehlversuchen wird die echte Exception geworfen (kein stiller Fallback). SSE-Stream-fetch unberuehrt. * fix(e2e): Fault-Recovery-Stages realistisch machen (Dependency-Health-Wait + up.sh-Post-Restart-Semantik + 1200s-Budget) Die neuen Fault-Stages (faultStageBitcoind/faultStagePostgres, hinter ZKCOINS_JOURNEY_FAULTS=1) starteten nach dem Dependency-Restore die Nodes SOFORT neu - ohne auf die Dependency-Health zu warten - und pollten nur 180s auf ready. Der node ist fail-loud by design (kein In-Process-Reconnect, kein restart:always, compose.yaml). Nach einem Node-Restart baut/laedt er die Circuits (bis Minuten) und verbindet bitcoind neu; up.sh gibt dafuer ein 1200s-Budget + Post-Restart-Sequenz. Die Fault-Stage tat das nicht -> node kam vor bitcoind hoch bzw. brauchte laenger als 180s -> 503 dependency_unavailable. Fix (nur die Fault-Stages): (1) waitComposeHealthy wartet via 'docker compose up -d --wait' auf die Dependency-Health VOR dem Node-Restart; (2) waitNodeStackPostRestart repliziert die up.sh-Sequenz (node Docker-Health 1200s -> node /health -> api Health -> api /health) fuer die betroffenen Nodes; (3) recovery-ready-Poll von 180000ms auf 1200000ms (etabliertes Node-Budget). Default-Journey-Pfad und Stages 1-11 byte-unveraendert. Kein Silent-Fallback (fail-loud ueber dockerCompose/fail). * fix(coverage): collect-Skript laeuft in einem Rutsch durch + Baseline mit Fault-Zweigen Zwei latente Bugs, die nie getriggert wurden (Unit-Teil starb immer vorher): (1) Der native Unit-Coverage-Lauf erbte die vom Aufrufer gesourcte env.local.sh (Live-Stack-Env), obwohl die Unit-Tests gegen die CI-Test-Env geschrieben sind (router_tests.rs leitet die gemockte Publisher-Adresse aus PUBLISHER_KEY=0000...0001 ab). Jetzt setzt der 0)-Zweig die 5 CI-Test-Vars (Quelle ci.yaml) vor dem cargo-llvm-cov-Lauf. (2) llvm-cov -path-equivalence schreibt die SF-Zeilen im lcov-Export NICHT um -> integration.lcov behielt Docker-/app-Pfade -> der node-only-Merge-Guard failte. Jetzt werden die SF-Pfade nach dem Export auf den Host-Checkout normalisiert (fail-loud). Baseline: neueste Messung (efb2781, MIT fault-bitcoind/fault-postgres-Journey-Stages): kombiniert node-only 77.5% lines (Integration-only 40.3->42.5% = die neu abgedeckten Fault-Recovery-Pfade). CI-Floor unveraendert. * review-fix(node): Hardware-Budget-Doku an v1-Realitaet, empty-ENV fail-closed, SDR-Doku-Drift, tote TODOs entfernt - CONTRIBUTING.md Hardware-Target: das veraltete <64GB/5s/30s-Legacy-Budget (ROADMAP step-9) durch die v1-Realitaet ersetzt: C-Circuit ~90-100 GiB Build/Prove-Peak auf dem 96-GB-Target ist bewusstes Design, abgesichert durch Secondary-Verifier-Cache + host-weite Proving-Lease + drop-when-idle; v1-Budgets werden aus gemessenen Samples abgeleitet (r2_budgets.rs), nicht als starre Legacy-Konstanten behauptet. - lib.rs: DATABASE_URL + USERNAME_DOMAIN jetzt fail-closed auch bei gesetzt-aber-leer (.ok().filter(!empty) .expect(), wie IS_MAINNET/ESPLORA) statt nur bei unset. - CONTRIBUTING.md SDR-Abschnitt: an die tatsaechliche BitcoindInclusionMtp-Produktionsrealitaet (bitcoind- Finality, >=6 confs, fail-closed) angepasst; recover_inscription.rs Module-Doc an die true/false-Panik-Semantik. - account_node.rs: zwei tote Legacy-TODOs (per git-history als von-Anfang-an-fehlplatziert belegt) entfernt. * review-fix(node): println!/eprintln! -> tracing in 9 Produktionsdateien CONTRIBUTING-Coding-Standard (No println! -> tracing::*): 103 Aufrufe in audit/db/flow/lib/main/ publisher/router/runtime/v1/receive.rs auf context-passende tracing::{info,warn,error}! migriert (Format-Args unveraendert, Semantik gleich). Verbleibende 4 Treffer sind reine Kommentar-Erwaehnungen, kein Aufruf. Tests + bin/ unangetastet. cargo check -p node gruen. * node: serve open token provenance (asset_terms) — store, kernel RPC, REST Implements the open Class-B token-provenance read (spec §4.6 / §7.5 / §7.8) so a token survives the loss of its issuer. - token_provenance store (migration 0037): asset_id -> canonical IssuanceTerms, append-only, never deleted; idempotent insert that fails loud on a conflicting value for an existing asset_id, never a silent overwrite. - receive path captures asset_terms atomically with the verified CoinProof in the same store-and-ACK transaction; a bundle without asset_terms leaves the coin opaque (no row), no error. - kernel GetTokenProvenance: open, no capability or feature gate; NOT_FOUND when no terms held, INVALID_ARGUMENT for a non-32-byte asset_id. - REST GET /v1/token//provenance: not features-gated, self-verifying §7.5 JSON (name as raw-byte hex; v1 and v2 schemas); 404 not_found / 400 malformed_request. - reuse the canonical IssuanceTerms bundle encoding for storage; expose the JobStore pool to the store-backed kernel service for this read. Tests cover every scenario at the store, kernel-RPC, receive and REST layers (v1/v2 self-verifying round-trip, idempotency, fail-loud conflict, unknown 404, malformed 400, opaque-without-terms, not-feature-gated) and fix the migration table-order assertion for the new table. * node: enforce the §4.3 recovery-discoverable overlap at publish Every delivery and self-delivery now additionally places its artefacts on the seed-discoverable set from the signed Bootstrap Manifest, so a seed-only scan is guaranteed to find both planes (spec §4.3): - publish_recovery_overlap: after the recipient-advertised placement, upload the blob to the manifest's network blob_stores and publish the gift-wrapped event to its network seed_relays. Both are a fail-closed publisher duty: an empty or fully-rejecting plane raises OverlapBlobStore / OverlapSeedRelay, never a silent success on the recipient-advertised copies alone. - the overlap errors are transient, so the existing outbox backoff retries them rather than terminating silently. - the verified manifest's seed_relays/blob_stores are threaded from the runtime through MeshDeliveryPort into publish_outbox_row and drive_due_outbox_entries; self-delivery (SelfDeliveryRecordV1) reuses the same overlap helper. Tests cover overlap satisfied on both planes, fail-closed on each plane, the self-delivery path, the no-manifest and no-seed-relay edge cases, and that the outbox row stays unpublished on an overlap failure. * node: make the §4.3 overlap recovery-discoverable and backfill existing terms Two gaps a review found in the fresh §4.3-overlap and provenance work: - Recovery could not find the manifest copy. The publish side placed the blob in the manifest's network blob_stores, but the seed-only recovery fetch only tried the recipient-advertised holders, so a scan could miss the manifest copy once those holders were gone — defeating the §4.3 guarantee. RecoveryCampaignDeps now carries the verified manifest blob_stores, and both recovery blob fetches (main scan and self-delivery) append them as fallback holders (recipient first, deduped). - Existing holders got 404 for terms they already held. token_provenance started empty and the receive replay short-circuits before the provenance insert, so an asset received before this feature stayed unresolvable. A one-time idempotent boot backfill walks the existing decrypt-index CoinProofs and restores their asset_terms. Tests cover recovery fetching a blob only from a manifest store, holder-list preference/dedup, and backfill restore/idempotency/skip-without-terms/fail-loud. The public-surface allowlist gains the new backfill export. * rebase: reconcile the rebased tree with the v1 rebuild content The linear rebase onto staging desynced a few files' final content in program-plonky2 (the monolithic-circuit removal, the dev-deps) and the node migration sequence. This restores the intended rebuilt tree and adopts staging's two post-fork deltas consistently: the docs.zkcoins.com domain (#230) — across the root-handler response, its test assertion and the remaining doc links — and the dedicated zkcoins-node CI runner pool (#225). * node: surface swallowed rollback errors and fail closed on an unusable clock The v1.1 finalise, SDR head recovery, and receive commit paths discarded the result of restore_live() after a failed apply/persist, so a failed rollback could leave in-memory state advanced with no matching durable write and no error. They now report a failed restore (naming both causes) while still preferring the original error, matching the loud handling already used later in finalise. The publisher terminal-mark and the reconstitute cache re-mirror now log a warning instead of dropping their errors. check_timestamp_window no longer substitutes epoch 0 for an unusable clock (which let a near-zero timestamp pass the freshness window); it fails closed and delegates to a new pure check_timestamp_window_at covered by unit tests. * node: route script-plonky2 finality and publisher logs through tracing The finality-broken safety signal, the prover-reaper panic note, and the publisher broadcast/fee decisions used eprintln!, bypassing the tracing pipeline. Adopt the workspace-declared tracing dependency for script-plonky2 and emit these through tracing (error/warn/info by severity). Drop a stray build-diagnostic print in the compliance skeleton circuit. * node: correct stale warmup docs and dangling module references warmup_prover is a no-op under the v1 on-demand prover lifecycle; its doc comment and the bootstrap log messages no longer claim a prove-based warmup runs. Remove references to the deleted scanner_runtime and scanner_ws modules from lib.rs, publisher.rs, and main.rs, and turn a stale TODO on ClientAccount into a neutral design note. * node: fall back to manifest blob stores when advertised holders fail The ordinary CoinProof delivery/recovery fetch (process_delivery_candidate) only tried the recipient-advertised holders, unlike the SDR path which already merges the network manifest blob stores via recovery_blob_holders. Per the recovery-discoverable overlap (spec 4.2/4.3), a coin whose advertised holders are all gone but whose blob still sits in a network blob store could not be restored. CandidateNetwork now carries the manifest blob stores (threaded from the recovery-campaign deps and, for the live poll, from the boot manifest), and the fetch merges them as a fallback after the advertised holders — advertised holders are still tried first, and a total failure still surfaces AllHoldersFailed. Adds an integration test that serves the blob only from the manifest store. * node: carry mint IssuanceTerms into CoinProof.asset_terms for provenance Every mint output was constructed with asset_terms: None, so the token-provenance transport (spec 6.5/4.6) never fired and GET /v1/token//provenance 404'd for freshly minted tokens. The raw terms only exist at mint-begin (the name is hashed away downstream and PendingTransition's wire format is frozen), so they are staged durably in a new v1_mint_terms_staging table keyed by pk_create at begin and read back at finalise by signature.pk_i to populate asset_terms on both self- and external-delivered mint CoinProofs; a mint finalising without staged terms fails loudly. The issuer's own node records a provenance row directly (self-delivery never reaches the recipient path). Ordinary sends keep asset_terms: None. Ships with the staging round-trip, material-construction, issuer-provenance, and schema tests. * node: gate the store-and-ACK credit on creating-nullifier finality verify_coin_proof_for_index emitted a terminal completed receipt on first-occurrence alone, ignoring whether the creating nullifier was final (spec 3.10 requires first-occurrence AND >=6 confirmations). A one-block reorg could orphan a coin a merchant had already treated as settled. The store-and-ACK gate now requires pos < size_final for the creating nullifier (the same finality idiom as the receive-transition gate); a not-yet-final nullifier is refused, and the existing scanner re-poll re-verifies and credits it only once it is final (defer, not a durable pending-receipt subsystem). Ships with non-final / later-final / orphaned / double-spend tests. * node: map the disabled SignTransition edge gate to a listed gRPC code The SignTransition feature gate returned UNIMPLEMENTED, which is not one of the eight admissible gRPC codes in the kernel.v1 error contract (spec 7.8) and carries no ErrorInfo. The refusal now routes through KernelError -> map_domain_err as INTERNAL / internal_error / 500 — the error table's own fallback for a condition outside a procedure's row — carrying the normative ErrorInfo, while keeping the fail-closed behaviour and the flag-naming detail. * node: key mint-terms staging by job id, not the account pubkey Review follow-up: v1_mint_terms_staging was keyed by pk_create (the account's current pubkey), which only rotates on an applied transition. A mint cancelled at awaiting_signature leaves the key unrotated, so a later different-terms mint on the same account reused pk_create and ON CONFLICT DO NOTHING silently kept the first attempt's terms, baking them into the second mint's CoinProof.asset_terms/token_provenance. The staging row is now keyed by the node-assigned, DB-unique job id (fence.job_id == the public_id used at stage time), so distinct attempts never collide; a divergent restage under the same job id is a hard error, and the issuer-side provenance insert now self-auths the recomputed asset_id against the output coin. Ships with distinct-job / divergent-conflict tests. * node: make the store-and-ACK finality gate atomic with the durable credit Review follow-up: the inbound store-and-ACK path checked creating-nullifier finality under the short-lived live-engine lock and then persisted + ACKed after releasing it, so a concurrent scanner reorg-restore (which holds EngineAdapter::lock_writes) could un-finalize the nullifier between the check and the credit. The gate now holds lock_writes across the verify and the durable insert and re-checks finality immediately before the insert, mirroring the receive path; the ACK follows after the durable commit. Adds a pipeline-level test asserting no insert/ACK before finality, and rewords the now-stale HoldersEmpty text (with its recovery-test twin) after the manifest-blob-store fallback merge. * node: fail closed on a missing bootstrap manifest and cover the clock path Review follow-up: the incoming-scanner spawn masked a missing/unloaded BootstrapManifest with an empty blob_stores list via unwrap_or_default(); it now bails like its sibling instead of inventing an empty set. Adds a unit test for the fail-closed 'Server clock unavailable' path via an injectable clock seam (the six existing tests only covered the pure window helper), and updates the last stale kernel-rpc-mapping doc/comment references from UNIMPLEMENTED to INTERNAL/ErrorInfo. * node: drop the dead staging column and cover the issuer self-auth rejection Second review round follow-up. The v1_mint_terms_staging pk_create column is redundant now that rows are keyed by the node-assigned job id (pk_create is derivable from the job) and it was never read — removed from the migration (unmerged, edited in place), the staging function, and its call site. Adds the missing negative test proving insert_issuer_mint_provenance rejects an output-coin asset_id that does not match the staged IssuanceTerms and persists no provenance row. Corrects the last stale SignTransition doc references from UNIMPLEMENTED to INTERNAL/ErrorInfo. --- .dockerignore | 7 + .github/coverage-baseline.md | 259 + .github/workflows/ci.yaml | 287 +-

Their correctness is secured by: + - the §1.7.9 circuit-digest generator (committed digests verified + in the heavy CI job), + - the Plonky2 prove-driven suite (mint / send / receive flows), + - the D-05 differential test against the reference implementation. + Line-coverage over circuit gadgets and gate tables does not add + signal comparable to those checks; counting those packages would + drown the floor in structurally un-executable paths. This is the + only package-level exclusion and must stay justified here if it + remains. +3. **No silent carve-outs.** If a production file must be excluded, the + reason is documented here — never only encoded in a regex. +4. **Floor does not sink.** CI enforces integer floors of the measured + totals via `--fail-under-lines` / `--fail-under-functions`. Raising + the floor toward 100 % is follow-up work; lowering it is a regression + that needs an explicit decision and an update to this file. + +## CI trigger note (endgame — not yet applied) + +Today the heavy gate still runs only when the `ci:full` label is present +(or on push paths that already carry it). Expanding it to every +non-draft PR (instead of label-gated only) belongs to the **CI endgame** +when the workflow is un-paused; do not flip that condition while the +workflow is still `workflow_dispatch`-only / PR-trigger-commented, or a +60–90 min gate would fire on every PR against paused runners.

This plugs the gap that opened while we were -//! disconnected — `scanner_runtime` already deduplicates against -//! `processed_blocks`, so re-publishing an already-processed hash -//! is a no-op. -//! - Every `connect_async` is wrapped in a 15 s `CONNECT_TIMEOUT` -//! (issue #84 round-4 MAJOR 1). A half-broken middlebox can stall -//! the TCP handshake for the kernel SYN-retransmit budget -//! (60-180 s on Linux/Darwin); bounding it explicitly lets the -//! reconnect-backoff loop drive recovery instead of stalling on a -//! single attempt. -//! -//! ### Wire format -//! -//!

A non-cyclic `C_balance` proof that the subject's account state holds +//! balance `B` of one `asset_id`, bound to the account's recursive +//! compliance proof and its on-chain nullifier `(Pk_anchor, R_anchor)` +//! via sign-to-contract, with the attested NAV a prefix of a disclosed +//! global `nav_ceiling` (§5.7 statements 1–7). The proof is network- +//! bound: `network_id = Hc("Network", network_tag_bytes)` is the last +//! public input of `C_balance`, and the proof verifies only under the +//! pinned `C_balance` circuit digest for that network. +//! +//! ## Edge — Bitcoin inscription locator +//! +//! The engine retains `NullifierOpening { pk, R, R' }` and the NfLog +//! `ChainPosition { height, tx_index, vin_index, member_index }`, but +//! **not** the reveal `txid` / `block_hash` of the inscription that +//! anchored the nullifier. Circuit public inputs include those fields +//! for host-side verification only (they are free in-circuit). +//! +//! Resolving a real `(txid, block_hash)` needs either: +//! - a durable scanner-owned `pk → (txid, block_hash)` index (not in +//! this worktree; scanner folds Pk/R only), or +//! - a still-live `v1_pending_publishes.reveal_txid` for **this +//! node's own** publish of that nullifier (partial, until GC), plus +//! the inclusion-block hash: live `tip_hash` when the nullifier +//! height equals the tip, otherwise the durable `block_log` row at +//! that height (completed anchors sit ≥6 confirmations below tip, so +//! they **must** use `block_log` — tip-hash alone can never serve them). +//! +//! When the locator cannot be resolved the job fails loud with +//! [`ATTEST_ANCHOR_LOCATOR_EDGE`] — never fabricates zero txid/block_hash. +//! Height is always taken from the NfLog chain position when present. +//! +//! Full E2E prove also needs a real multi-minute `C_balance` build on +//! first use (`ProverBridge::prove_attestation`).
