From 573a4df02797142c1c1e8b4428db7fb82ba120c5 Mon Sep 17 00:00:00 2001 From: RNT56 Date: Fri, 10 Jul 2026 13:44:26 +0200 Subject: [PATCH 1/2] fix: repair every finding from the features-completeness review MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit An 11-agent adversarial audit of the whole tree found 11 HIGH defects (all independently verified, four reproduced with runnable proofs), ~48 MED and ~70 LOW. This fixes all of them. Every fix carries a discriminating test: one that fails on the pre-fix code and passes on the fix. The verifier is the only authority on "done" (I2), and it was compromised four independent ways: - code.test_passes built `go test -- ''`, which go test reads as test-binary args for the CURRENT directory. The selected package was never tested; a green root greened a red package. Now `go test `. - The vcache key under-covered the composite it wrapped: the content hash skipped .nilcore (so a rewritten artifact replayed an old chain-verified pass) and the key omitted the browser-verify command, the verify-pack list, the evidence toggles and the sandbox image. Turning a check on replayed a green recorded with it off. - Evidence verifiers were discovered EAGERLY, at env construction, before the backend ran — when .nilcore/artifacts/ is necessarily empty. The composite froze with zero evidence legs and never checked the run's own artifact. Now lazy, as the build path already was. - swarm --resume re-seeded only failed and passed-unmerged shards. A DAG dependent skipped because its dep failed persists as StatusQueued, which neither source reads, so a resumed run converged exit 0 with planned work never executed. Red budget-exhausted shards now also block a clean converge. Also: the tiered fast path armed on the wrong leg of a compound command and dropped -run/-skip; validateVerifyPacks (the documented "explicit startup signal") had no caller at all. Security and liveness: - browsersession scrubbed typed secrets from page text, title, console and element values but NOT Observation.URL — a secret typed into a GET form reached the model prompt and the append-only event log. Its test never asserted the URL, so it passed blind (I3). - termui's spinner stop closed its channel and joined the animator while holding the console mutex the animator needed. Reproduced; fixed with TryLock so a dropped frame, never a wedge. - MCP's stdio WRITE side was not ctx-cancellable: Encode blocked forever under the transport mutex against a peer that stopped draining stdin, permanently leaking a serve drive slot. Responses are now size-capped (a hostile server could OOM the host) and children are reaped. - session persist ran on the ctx the drive had just cancelled, so conversation state never wrote and the error was swallowed. Detached via context.WithoutCancel. Session.Checkpoint had zero callers; now wired. - An empty-content model reply was appended verbatim and poisoned history, killing the run terminally. Reachable: the Anthropic decoder drops server_tool_use blocks, so a web-search-only turn decodes to empty. Shipped features that were structurally inert: - Graduated auto-approval could never fire. Presets use AllowBranches ["*"], matched by path.Match, whose * never crosses '/' — but every real gate scope is a slash-y branch. Trust and the per-day rate/dollar windows keyed on per-run-unique scopes, so MinSuccesses was unsatisfiable and MaxPerDay and MaxDollarsDay never bound. Now * matches any non-empty scope and the three windows key on a stable scope FAMILY. The protected-base floor, DenyBranches, the kill-switch and the chain-verified requirement are unchanged and still evaluated on the CONCRETE branch. Fixing reachability exposed the dollar-window bug, which is fixed here too. - self-improve had NO merge step: Propose logged self_edit_merged and returned merged=true while nothing merged. A real Flow.Merge seam now lands the verified branch, and merged=true means it landed. - swarm derived each shard's egress and dropped it on the floor; every shard ran --network none, so the research preset could never verify green and --egress-allow was inert. The allowlist proxy now enforces the ROLE-INTERSECTED set (never the operator's wider tree) and the change to what a shard may reach is announced and audited. - memory/lessons and operator steering reached only run/watch, never the doors people use (chat, TUI, serve). -blast-radius fenced neither chat nor serve native drives. A serve-restart-resumed run had no dollar ceiling. serve's --webhook opened a second SQLite handle on the DB serve owned. BEHAVIOR CHANGE, deliberate and double-opt-in: with NILCORE_SELFIMPROVE_AUTOAPPROVE=1 the flywheel previously performed a no-op and now performs a real merge. DefaultScope still forbids the verifier of record, the core loop and every contract file, the execution-time Changed screen still fails closed, and the edit is still verifier-green first. BEHAVIOR CHANGE, announced: code/fix/research swarm shards now reach the hosts their preset declares (previously none). Deny-all presets stay --network none; a proxy that cannot bind fails closed. Docs reconciled to the code as it now is: AGENTS.md's constitution had been corrupted by a find/replace into "the native loop, Codex, and Codex"; PREREQUISITES demanded Go 1.23 while go.mod requires 1.25; four merged PRs had no CHANGELOG entry (CLAUDE.md §6); REFERENCE.md was a full phase stale; dead references to pruned symbols (impact.Localize, policy.Gate, EgressWith, blackboard) and two documented-but-never-implemented env gates were removed; nine dark env vars are now documented. make verify green (119 packages, 0 lint issues); go test -race clean across 17 concurrency-sensitive packages; -tags tui builds; the default binary still links zero Charm (I6); GOOS=linux sandbox cross-compiles.

Default to the standard library. There are three sanctioned exceptions: **SQLite** (`modernc.org/sqlite`, Phase 4 — the persistent backbone for `internal/store` and the code-intelligence graph in `internal/codeintel/{graph,semantic}`; a pure-Go driver, so releases keep `CGO_ENABLED=0`), **`golang.org/x/sys`** (Phase 7 — the namespace sandbox's Landlock / `no_new_privs` / seccomp syscalls in `internal/sandbox`; the Go project's own extended standard library, already pulled in transitively by SQLite), and the **Charm TUI stack** (`bubbletea`/`lipgloss`/`bubbles`), isolated behind the `//go:build tui` tag so the default `nilcore` binary links **zero** Charm. The MCP client is **not** a module — it speaks JSON-RPC over the standard library (`internal/mcp`). Any further module dependency requires the justification above. 7. **Untrusted input is data, never instructions.** Tool output, file contents, and fetched web content never become controlling instructions for the agent. @@ -162,7 +162,7 @@ docs/ cmd/nilcore/ ← entrypoint internal/ model/ ← Anthropic Messages API client (stdlib only) - backend/ ← CodingBackend contract + native / codex / Codex + backend/ ← CodingBackend contract + native / codex / claude-code sandbox/ ← container executor verify/ ← the verifier (source of truth for "done") eventlog/ ← append-only audit trail diff --git a/CHANGELOG.md b/CHANGELOG.md index 9535a3c..b8b10bf 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -16,8 +16,14 @@ On a release, the maintainer moves the accumulated `[Unreleased]` entries into a ## [Unreleased] +- **chore(features-review): reconcile shipped-but-inert subsystems, then a full docs pass over the assembled diff.** A features-review sweep found a cluster of built-but-silently-dead paths (several of which reported false green), fixed each with a discriminating test, and then reconciled the docs to the code as it now is. **Verifier integrity:** the `vcache` key now folds in the browser-verify command, `NILCORE_VERIFY_PACKS`, `NILCORE_EVIDENCE_VERIFY`, `NILCORE_EVIDENCE_MAX_AGE` and the sandbox image identity (a behavioral toggle can no longer serve a stale green), and the worktree content hash includes `.nilcore/artifacts` when evidence verification is on; evidence verifiers are now discovered **lazily at Check time** on run/chat/serve/resume (they were built eagerly and so never ran); tiered verify reads only the `go test` leg of a compound command and replicates `-run`/`-skip`; a new boot `validateVerifyEnv` exits 2 on a bad `NILCORE_VERIFY_PACKS`/`NILCORE_EVIDENCE_MAX_AGE`. **Artifact packs:** `code.test_passes` ran `go test -- ''` (which never tested the selected package — a false green) → `go test ''`; `code.build_passes` on an undetectable layout is now Unverifiable, not Pass; `schema_verify` events are actually emitted (the report's SchemaDefects section was permanently empty; `DefectMeta` gained `claim_id`/`reason` + json tags); `software.github_tag_exists` paginates; the audit pack rejects leading-dash patterns. **Swarm:** shards now actually receive their derived egress (an allowlist proxy is stood up and applied per shard box — previously every shard ran `--network none`, so the research preset could never verify green and `--egress-allow` was inert); `--resume` re-seeds skipped/queued/running shards (planned-DAG dependents were being dropped — a false green) and red budget-exhausted shards block a clean converge. **Graduated auto-approval (graapprove) was structurally unreachable:** `AllowBranches:["*"]` never matched slash-y branches (`path.Match`) and trust/rate keyed on per-run-unique scopes — now `*` matches any non-empty scope, and trust + the per-day rate window key on a stable scope **family** (`task/trig-123`→`task/*`, a bare sha→`#commit`); the protected-base floor (main/master/release/trunk/stable/prod*) and `DenyBranches` stay on the **concrete** branch; an empty scope never auto-approves. **Self-improve now really merges:** it had no merge step (it logged `self_edit_merged` and returned `merged=true` while nothing landed) — there is now a real `Flow.Merge` seam, `Run` returns the verified branch, `merged=true` means it actually landed, and new event kinds record the failure modes (`self_edit_merge_unwired`/`self_edit_no_branch`/`self_edit_merge_failed`). **Session / front door:** drive-terminal persist ran on an already-cancelled ctx so conversation state never wrote (now detached — `context.WithoutCancel` + 5s timeout); `Session.Checkpoint` (previously zero callers) is now called on chat exit and in serve's drainShutdown; steer markers (`!`/`/steer`) are stripped before the model sees the turn; memory/lessons (`MemoryContext`) and operator steering (`SteeringContext`) now reach chat/TUI and serve, not just run/watch; `-blast-radius` now fences chat and serve native drives (chat mints ONE shared blast budget for its proxy + sandboxes + gate; a serve-restart-resumed run gets the dollar ceiling); serve's `--webhook` no longer opens a second SQLite handle on the DB serve owns; the serve-embedded flywheel gate is deny-default (was bound to `os.Stdin`); a failed serve drive no longer renders "✓ not verified" over Telegram/Slack. **Security / robustness:** `browsersession.Observation.URL` is scrubbed for typed secrets (an I3 leak into the model prompt AND the append-only log); browseragent irreversible-signal, `router.Classify`, `trust.Classify` and `session.referencesGoal` moved from substring to word-boundary matching; Slack model text is escaped (was ``-injectable), evidence-rich gates clip to Slack's 3000-char cap instead of silently auto-denying, 429/Retry-After is honored, and ws frame length is sanity-checked; Telegram scrubs the token from transport errors and clips long messages; MCP stdio writes are ctx-cancellable (a deadlock), responses size-capped, children reaped, stale resource/prompt wrappers pruned; one malformed SKILL.md no longer disables ALL skills; codeintel + live walks skip symlinks (I4) and vendor dirs (node_modules/vendor/.venv/dist/build), and several tool reads moved to `O_NOFOLLOW`; the termui spinner stop/animate deadlock is fixed (TryLock). **Backends / providers:** an empty-content native reply no longer poisons history and kills the run; Anthropic — a zero-frame clean-EOF stream is a retryable error, server-tool-only (`pause_turn`) turns are preserved, all beta headers collected; OpenAI — web plugin deduped, tool_result error signalled, max_tokens splice fixed; codex/claude-code `digText` matches the real claude-code stream-json (`result` key, `message.content[]`). **Also:** experience projection is rotation-aware (`Rebuild` drops stale keys); autosrc no longer kills a source permanently on a full queue; emit neutralizes ANSI in gate evidence; integrate stops on a failed `merge --abort`; the eventlog torn-tail heal won't drop committed lines; the report writer error-lists as json. **Docs reconciled to the code:** restored the AGENTS.md backend set (a find/replace had corrupted it to "Codex, Codex"), corrected Go 1.25 + dropped the never-adopted `sqlc` in PREREQUISITES, purged dead-symbol references (`impact.Localize`/SBFL, `policy.Gate`/`EgressWith`, `internal/blackboard`, `emit.NopEmitter`, `objective.MarkRun`), corrected the phantom `NILCORE_BROWSER_AGENT`/`NILCORE_DESKTOP_DARWIN` gates to the shipped gating, documented the previously-undocumented env vars in `docs/REFERENCE.md`, refreshed the stale REFERENCE.md metrics/CLI/package inventory, and stated the true Phase-15 status (web search shipped;

(2) an unvalidated SKILL.md frontmatter `name` became the `skill_` API tool name, so one malformed installed skill 400'd EVERY model call of every run — the name is now sanitized/validated at load, the `Defs()` boundary skips+warns any tool violating `^[a-zA-Z0-9_-]{1,64}$` (legit builtins unaffected), and `registry.InstallSkill` validates at install. **Confirmed clusters fixed:** *silent-failure bugs* — `scheduler.Submit` deadlock on >1024 tasks submitted pre-Start (→ unbounded cond-queue, FIFO/bounded-concurrency preserved); a swallowed `wt.Commit` fault stranding a verified green shard as a false-green (→ surfaced not-done); `resilience.Stream` double-paint across a retry (→ concat(forwarded)==returned invariant preserved); the MCP `Manager` single-flight binding the shared connect to one caller's ctx and poisoning a concurrent peer (→ detached connect ctx). *Dead-as-advertised closed-loop features* — trusted-preset Deploy auto-approval unreachable;

`-blast-radius` wall fence unenforced on the DEFAULT Linux namespace backend (→ wired via a build-tagged helper). *Invariant edges* — the read-path final-component symlink TOCTOU across read/edit/editchecked/format/patch (→ `worktreefs.ReadConfined` O_NOFOLLOW, false hardening comment corrected); `maint.RotateLog` overwriting a hash-chained generation (→ lossless multi-generation, I5); macOS keychain `Set` leaking the secret on argv (→ off-argv); MCP `Headers` promising host-side secret resolution no code performed (→ `{{secret:NAME}}`/`{{env:NAME}}` resolved via the SecretStore, unresolved = hard error;

the embedder hardwired to api.openai.com (→ `NILCORE_EMBED_BASE_URL`); the semantic index mixing vectors across embedding models (→ model+dimension-keyed cache). **Contract/infra/docs:** `make verify` now runs golangci-lint (the dogfooded gate matches CLAUDE.md §4 + CI); the `-race` lane gained model/meter/mcp/trace/trust/graapprove (their `*Race*` tests stop being tautological); a new CI job runs the CONTAINER-sandbox I4 confinement+egress tests under `NILCORE_SANDBOX_MUST_RUN` (the primary sandbox boundary had zero regression protection); `tui-verify` now covers the swarm-board + trace tui code; releases publish per-binary SHA-256 + a SHA256SUMS and the installer verifies before installing (fail-closed); a hermetic model-free native-loop convergence smoke test proves the core loop in CI; doc drift fixed (the non-existent `nilcore run` in SELFACC/ARCHITECTURE/CLAUDE, the vestigial `nullclaw` `docs/.gitignore`). **Then a 12-slice adversarial review of the ASSEMBLED diff caught 8 confirmed second-order regressions the tests missed** — all fixed: a `mkdirAllNoFollow` boundary fallback that could still FOLLOW an attacker-swapped in-worktree symlink out of the tree (I4 escape — reproduced, then closed by canonicalizing root AND target in one symlink-space); the graded auto-approval `$` meter denying everything under the default `-blast-radius off` because it charged cumulative run spend as one action's cost (→ per-day metering against `MaxDollarsDay` seeded from the durable log, `min(clause, blast dayCeil)` when a budget is present, structural main/prod/release denials intact); repomap PageRank dropping ALL call edges post-migration (raw `Edges` vs resolved `CallEdges`); the macOS `ConfigDir` move orphaning an existing secrets vault on upgrade (→ reverted to the stable Application Support home, mint-a-fresh-key data loss averted); `route.Race` loser-cancel making the winner nondeterministic (→ index-aware: a passer cancels only strictly-higher indices, so the lowest-index passer always wins); a chat stdin close-on-ctx racing `os.ErrClosed` into `fatal()` on a clean Ctrl-C (→ mapped to a clean end). A ninth (lowering the high-entropy redaction floor to mask bare hex) was applied then REVERTED when it proved to also mask the audit log's own content/chain/cache-key hashes — breaking the verify cache (a cached-green test surfaced it); the belt's comment now documents why context-free hex is deliberately not masked (keyed hex secrets are still caught by the prefix rules). `make verify` (119 pkgs, lint-inclusive) + Linux cross-build + the expanded `-race` lane + a fully-uncached `go test ./...` all green. _Owns:_ repo-wide — `internal/*`, `cmd/nilcore/*`, `.github/workflows/*`, `Makefile`, `scripts/install.sh`, `docs/*`. _(audit remediation)_ - **feat(upgrade-program): execute the judge-ranked upgrade program — 17 items across 5 waves (dormant loops · context lifecycle · verification latency · swarm DAG completion · delivery loop + gate evidence + sandbox hardening).** A 9-lens, 3-judge analysis over the whole tree (58 scored proposals) found the recurring shape "the system records what it never consumes and builds what it never wires"; this executes the top-ranked program. **Wave 1 — wire the dormant loops:** the Anthropic adapter now emits the **3 prompt-cache breakpoints** (system block-array, last tool, moving last-message marker; Complete+Stream shared; ≤4-bound respected) whose 0.25x read pricing the meter always accounted for — and activating it exposed a REAL dormant bug: Anthropic reports *disjoint* usage tallies while the pricer assumes totals, so a live cache would have massively under-billed; `toModelUsage` now folds `input+cache_read+cache_creation` (test-pinned). The **lessons last mile** is closed — `memory.TaskContext` merges ScopeProject + ScopeGlobal (where the distiller writes) under one newest-first budget, so the agent finally sees its own scars; **race escalation** threads the failed attempt's fail-class + fenced verifier tail into each candidate's `Constraints` (the most expensive escalation no longer starts blind); **`final_verify` is class-tagged and folded into the trust ledger** alongside `race_outcome` (skip-not-panic guards; pre-upgrade logs replay byte-identical) so per-class routing warms on single-backend deployments; **`read` gains {offset,limit} paging + a 48KB cap** with a recovery-teaching notice and the mcp result is capped at the shared fence seam. **Wave 2/3 — context lifecycle + verification latency:** the native loop bounds shell/registry output (head 2KB + tail 6KB backstop; self-bounded tools exempt), records structured edits in the advisor trail, handles `max_tokens` (16384 default cap, `textBlocks()` salvage + harness re-emit turn + `json.Valid` belt — a truncated tool call no longer spins the nudge), injects a one-shot budget wrap-up signal, prepends a **fenced repo map** (new bounded `repoMap` walker behind the `RepoContext` seam) and **compacts in-run** (`CtxWindow` from the meter's window table; `msgs[0]` kept byte-identical to preserve the cache prefix; pairs never split; tool bodies excluded from summaries — I7; context-overflow 400 ⇒ compact-once-retry instead of losing the worktree; events `truncated_turn`/`budget_wrapup`/`loop_compact`). **`NILCORE_VCACHE` flips default-on** (kernel-cutover pattern, `=0` hatch) killing the pure-waste 2x verify on every success; a **FlakeProbe** decorator (test-class red + identical content hash ⇒ ONE real-verifier re-run; `verify_flaky` event) stops a coin-flip test from triggering an N-worktree race; a **TieredVerifier** (**opt-in**, `NILCORE_TIERED_VERIFY=1`) short-circuits in-loop RED via scoped `go vet`+`go test` of touched packages — armed ONLY for a full-module `go test ./...` command whose flags it replicates, short-circuiting ONLY a *provable* subset red (a package-load error falls through to Full); only the FULL verifier can PASS — I2 by construction; order `tiered(flakeprobe(vcache(base)))`. The `vcache→flake→tiered` chain is wired on every orchestrator path (run/serve/chat/resume), not just build/swarm, so a green run pays ONE full verify (not two) and a flaky final verify is re-probed once before any N-worktree race. **Wave 4 — swarm DAG completion (extends #94):** `Shard.BaseRef` + dependency-aware base resolution (single dep ⇒ its verified branch; multi ⇒ integrated TipSHA, `super.depTip` pattern) with a bounded fenced claim-status+summary handoff — DAG edges now buy the dep's CODE, not just ordering; **merged-set tracking** stops the every-pass re-merge spam and a **conflict requeue** rebuilds a conflicted-but-green shard on the integrated tip under the requeue Ledger; **termination honesty**: `Outcome.Unmerged` folds into `Remaining` so a silently-dropped green can never exit 0; **evidence-carrying focused requeue** (red keeps its branch; retry continues from it with red claim ids + verifier detail in the goal); fixed a latent blocker (attempt-branch name collisions made ANY shard retry fail at the worktree cut — now uniquely suffixed) and armed the always-zero requeue budget via `--retries` (default 2). **Wave 5 — delivery + gates + sandbox:** verified chat/run drives **keep their branch** (the front door no longer verifies work then deletes it) with `/diff` preview and `/apply` merging through the EXACT structured PromoteToBase gate (maint caps kept branches; WorkState survives restarts); **every attended gate shows evidence** — `policy.GateEvidence` (diffstat + bounded head-biased excerpt + verify tail with verdict line + spend, redacted at construction) rides `GateAction.Evidence` through the existing StructuredApprover seam, mirrored to `emit.GatePrompt`, rendered on console/plain-writer/styled-REPL/TUI/Slack/Telegram, with legacy flat approvers byte-identical (pinned) and the graapprove fall-through forwarding the FULL action (11 sites; previously every graded fall-through flattened to one line); the **namespace sandbox masks operator credentials** before Landlock — vault dir + `~/.ssh`/`.aws`/`.gnupg`/`.netrc`/`.config/gh`/`.docker/config.json`/`.codex`/`.claude*` (ro tmpfs over dirs, `/dev/null` over files, fail-closed 126, worktree-shadow exclusion) — closing the in-box vault-decryption I3 hole.

This builds it. New **`internal/router`** (pure stdlib leaf, deps-guarded, mirroring `agent.TrustOracle`): `Classify(goal) Preset` — a deterministic keyword bucket picking the cheapest preset that fits (breadth/parallel → `swarm`; project/scaffold → `build`; else `run`); an `Oracle` seam for a future learned/model-backed router (`nil ⇒ Classify`); and `Route(ctx, oracle, goal, allowed) (Preset, provenance)` — fail-closed (a nil/no-opinion/out-of-bounds/invalid oracle pick, or a heuristic pick outside `allowed`, falls back safely; never returns an unrunnable choice). New **`nilcore do -goal "…"`** entry routes a goal and dispatches to the chosen proven machine (`-dry-run` previews the decision, `-as` forces a preset, `-preset` passes a swarm preset); it adds NO execution of its own — the chosen machine still owns verify (I2), gate (I3), and log (I5), and the routing only ORDERS the machine choice (I7: the goal is inert data). Additive + opt-in: the explicit `run`/`build`/`swarm` commands are unchanged. **Design discovery recorded** in `docs/ROADMAP-KERNEL-V2.md`: the *iterative* `project.Loop` (plan one slice → judge → reflect → repeat) does NOT fit the kernel's *one-shot* `Recursive` fan-out, so it is deliberately NOT re-expressed (a lossy, risky fit); the native recursive engine stays available, tested, and dormant until a genuine static-decompose workload justifies a `decompose` preset + cross-worktree integrator (specced, not built — no hardening of consumer-less code).

Fix: a shared `evalUntil` poll re-evaluates the actionability check over a bounded budget (default 3s, 50ms interval), tolerating transient evaluate errors during navigation, so both selector-targeting commands wait for the element to become present + actionable instead of failing immediately — mirroring the auto-wait every mature browser-automation tool performs.

The wait budget is a configurable `Conn` field (tests set it sub-tick to keep the no-match path fast).

Docs-only (no code); `make verify` green. _Owns:_ `CLAUDE.md`, `docs/ARCHITECTURE.md`, `docs/TASKS.md` (contract docs, serialized). _(promotion)_ - **CU-MAC-T07 + T09 (native-macOS host-control hardening — permission probe, kill-switch, per-app allowlist)** — completes the verifiable host-control tier of `docs/ROADMAP-COMPUTER-USE-DARWIN.md`. **T07 live permission probe** (`cmd/tools/nilcore-desktop-darwin/permissions.go`): `--probe` (also `nilcore desktop --mac-probe` and `make desktop-mac-probe`) checks LIVE TCC readiness by *attempting a real `screencapture`* (the `could not create image from display` failure is the ungranted Screen-Recording signature, confirmed empirically) rather than the stale, launch-cached `AXIsProcessTrusted`, plus cliclick presence — emitting ordered, actionable "grant X in System Settings, then restart" guidance and exiting non-zero when not ready (a host-readiness gate). **T09 host-gate hardening** (`…/hardening.go`): a **kill-switch** (`$NILCORE_DESKTOP_STOP`, else `~/.nilcore/desktop/STOP` — `touch` it to halt all actuation instantly) and a **per-app allowlist** (`NILCORE_DESKTOP_ALLOW_APPS="App1,App2"` pins the agent to those frontmost apps via an `osascript` seam), both **fail-closed before every mutating act** (click/type/key/scroll) — an unidentified frontmost app under a set allowlist is refused. The host-control banner now surfaces all three. Fully hermetic: probe (faked capture/lookPath seams), kill-switch (temp sentinel), allowlist (faked frontmost), and the guard's wiring into `perform` are unit-tested; `golangci-lint` clean; `make verify` green; the live `osascript`/`screencapture` paths are the operator's (TCC-gated). **I4 stays relaxed only on the doubly-gated `--mac-host` path — and these controls narrow that surface.** _Owns:_ `cmd/tools/nilcore-desktop-darwin/{permissions,hardening}.go` (+tests), `cmd/nilcore/desktop.go` (mac-probe + banner), `Makefile` (desktop-mac-probe). _(Phase CU — darwin hardening)_ diff --git a/CLAUDE.md b/CLAUDE.md index 1945b16..bc78115 100644 --- a/CLAUDE.md +++ b/CLAUDE.md @@ -180,8 +180,8 @@ internal/ blastbudget/ ← Phase 16 the hard runtime fence (hosts · irreversible · sandbox wall · per-day auto-approval $) the auto-approval envelope reads flywheel/ ← Phase 16 self-improvement flywheel (selfeval · distiller · measure · loop) — verified, human-gated, never edits the verifier of record autosrc·objective/ ← Phase 16 autonomy daemon (bounded source queue) + operator-only standing-objectives backlog - kernel/ ← Phase 16 Pillar 8: the UNIFIED orchestration kernel — one recursive Run over Node/Envelope; run/build/swarm are presets, the router picks an envelope not a machine (pure leaf; machines inject as RunFunc/Plan/Integrate; default-on via NILCORE_KERNEL [escape hatch =0], equivalence-proven) - router/ ← Phase 16 Pillar 8 (UOK V2): the preset ROUTER that completes the kernel — Classify(goal)→run|build|swarm + an Oracle seam; backs `nilcore do` so the agent picks how to work (pure leaf; only orders the machine choice — never overrides a verdict/gate; docs/ROADMAP-KERNEL-V2.md) + kernel/ ← Phase 16 Pillar 8: the UNIFIED orchestration kernel — one recursive Run over Node/Envelope; run/build/swarm/decompose are presets, the router picks an envelope not a machine (pure leaf; machines inject as RunFunc/Plan/Integrate; default-on via NILCORE_KERNEL [escape hatch =0], equivalence-proven) + router/ ← Phase 16 Pillar 8 (UOK V2): the preset ROUTER that completes the kernel — Classify(goal)→run|build|swarm|decompose + an Oracle seam; backs `nilcore do` so the agent picks how to work (pure leaf; only orders the machine choice — never overrides a verdict/gate; docs/ROADMAP-KERNEL-V2.md) ``` New packages introduced by later phases are listed as **extension points** in `docs/ARCHITECTURE.md` and owned by specific tasks in `docs/TASKS.md`. diff --git a/README.md b/README.md index 068a3e0..36136d0 100644 --- a/README.md +++ b/README.md @@ -105,7 +105,7 @@ Code is one artifact type among many — reports, comparison matrices, audits, b ▸ **Code intelligence** (**19 languages** — Go · Python · TS/JS · Rust · Java · C/C++ · C# · Ruby · Kotlin · Swift · …; heuristic scanners, LSP = the precise lens) -AST · call graph · PageRank repo‑map · LSP · pure‑Go **HNSW** semantic search · Impact Set + SBFL · live worktree‑aware updates. +AST · call graph · PageRank repo‑map · LSP · pure‑Go **HNSW** semantic search · Impact Set + affected-tests · live worktree‑aware updates. ▸ **It can see the running app** A sandboxed headless browser (`browser_view`) can **drive a flow first** (click / type / key / wait — log in, submit a form) over a pure‑Go CDP client, then hands the model a screenshot as a multimodal image; opt‑in, a composite verifier folds the behavioral check into the verdict. *(Live run is CI‑only; fails closed without a browser.)* diff --git a/cmd/nilcore/blast.go b/cmd/nilcore/blast.go index 49f084f..316c6cb 100644 --- a/cmd/nilcore/blast.go +++ b/cmd/nilcore/blast.go @@ -117,6 +117,22 @@ func rebuildBlastDay(b *blastbudget.Budget, logPath string) { sum += autoApprovalActualUSD(d) } } + // A scan fault (an over-long line, a read error) means we did NOT see the whole log, + // so today's rebuilt total may be an UNDER-count — the fail-OPEN direction on a safety + // ceiling (it would let the day's auto-approval $ run past its cap).

Fifteen surviving defects were re-fixed. The code is untouched: markdown only. Load-bearing corrections: - router.Classify(goal) returns run|build|swarm — NOT |decompose. Decompose is a fourth Preset, opt-in only ("Classify never auto-selects it; it is not in All()"), reached solely via `nilcore decompose` / `do -as decompose`. CLAUDE.md, AGENTS.md and docs/TASKS.md all asserted the wrong return set. - docs/ARCHITECTURE.md overstated the container egress control. It claimed an allowlist proxy "is the only way out" and summarized it as an "SSRF-safe egress allowlist". In fact Container.AllowEgressVia only sets --network bridge and HTTP(S)_PROXY, and no iptables/nftables filter exists anywhere in the tree: enforcement is at the PROXY layer, honored by proxy-aware clients, not at the packet layer. The proxy is the only *sanctioned* way out, not a hard network wall. Egress is off by default, and the namespace backend (the Linux default) has no proxy path and is unconditionally deny-all. Both the §Execution-model prose and the §Security summary now say this precisely. - Metrics refreshed against the code everywhere they appear: 120 packages (111 under internal/), 375 source + 406 test files, ~89.8K non-test LOC, ~177.5K total, Go 1.25. - Six operator env vars were documented only in suffix shorthand (NILCORE_OPENROUTER_{MODELS,REASONING,TRANSFORMS,PLUGINS}, NILCORE_COMPAT_{AUTH_SCHEME,KEY_ENV}) and so were unfindable by their exact name; they are now spelled out, along with the four prefix-constructed NILCORE_{CODEX,CLAUDE}_{MODEL,EFFORT} that a literal grep misses entirely. - docs/REFERENCE.md gained an upgrade note for the two settings whose MEANING changed at 573a4df: NILCORE_SELFIMPROVE_AUTOAPPROVE=1 was a no-op and now performs a real merge, and `nilcore swarm` shards now reach their preset's declared hosts (they previously ran --network none). - Roadmap and plan docs keep their plans but now carry accurate SHIPPED / PARTIALLY SHIPPED / NOT BUILT status, and no longer name pruned symbols (impact.Localize, policy.Gate, EgressWith, internal/blackboard, emit.NopEmitter, objective.MarkRun, route.SingleRouter) as live. Where a doc claimed a feature worked that in fact never did — graduated auto-approval was structurally unreachable; self-improve logged a merge it never performed — it now says so plainly rather than quietly rewriting itself. CHANGELOG.md history is untouched (append-only; 224 -> 225 entries, none removed). No .go, Makefile or CI file changed; `go build ./...` still clean.

The native loop, Codex, and Claude Code all satisfy it. Changing `Task`, `Result`, or the interface is a dedicated, serialized contract task — never a side effect of another change. 2. **The verifier is the only authority on "done."** No backend's self-report (`Result.SelfClaimed`) decides whether work ships. After any backend runs, the project's checks re-run and that verdict governs. 3. **No ambient authority.** Secrets are held by the `SecretStore` (environment, OS keychain, encrypted vault, or external) — never written to disk in plaintext, never logged, never placed in a prompt or in source, and never given to the model. The process holds no broad credentials by default. -4. **Model-emitted execution is sandboxed.** Any *shell command* a model emits, and any delegated coding CLI (Codex, Claude Code), runs inside the container sandbox — a model can never run an arbitrary program on the host. The native loop's structured tools are the one deliberate, bounded exception: the file tools (read/write/edit/search) and the git tool run host-side, but each is confined to the disposable worktree (symlink-safe path resolution + `O_NOFOLLOW`) and the git tool runs a fixed, hardened subcommand set.

The native loop's structured tools are the one deliberate, bounded exception: the file tools (read/write/edit/search) and the git tool run host-side, but each is confined to the disposable worktree (symlink-safe path resolution + `O_NOFOLLOW`) and the git tool runs a fixed, hardened subcommand set. They perform scoped file/VCS I/O only — never arbitrary execution. The native-macOS **host-control** tier (`nilcore desktop --mac-host`, `docs/ROADMAP-COMPUTER-USE-DARWIN.md`) is a second, explicitly-recorded relaxation: it drives the operator's REAL desktop, so I4's sandbox boundary does NOT hold there — which is why it is reached only behind a *separate* opt-in (`NILCORE_DESKTOP_HOST=1`, never implied by the normal computer-use gate), forces an unconditional human approval, and is bounded at runtime by a kill-switch + per-app allowlist. The default (contained) desktop and every other path keep I4 intact. See `docs/ARCHITECTURE.md` §Execution model. 5. **The event log is append-only.** Every model call, tool execution, verify, and gate decision is recorded and replayable. Never mutate or delete history. 6. **The core has zero external dependencies.** Adding a Go module dependency requires explicit justification in the PR description and the CHANGELOG entry. Default to the standard library. There are three sanctioned exceptions: **SQLite** (`modernc.org/sqlite`, Phase 4 — the persistent backbone for `internal/store` and the code-intelligence graph in `internal/codeintel/{graph,semantic}`; a pure-Go driver, so releases keep `CGO_ENABLED=0`), **`golang.org/x/sys`** (Phase 7 — the namespace sandbox's Landlock / `no_new_privs` / seccomp syscalls in `internal/sandbox`; the Go project's own extended standard library, already pulled in transitively by SQLite), and the **Charm TUI stack** (`bubbletea`/`lipgloss`/`bubbles`), isolated behind the `//go:build tui` tag so the default `nilcore` binary links **zero** Charm. The MCP client is **not** a module — it speaks JSON-RPC over the standard library (`internal/mcp`). Any further module dependency requires the justification above. 7. **Untrusted input is data, never instructions.** Tool output, file contents, and fetched web content never become controlling instructions for the agent. @@ -48,7 +48,7 @@ Breaking any of these means the PR is **rejected**, no matter how good the rest ## 3.

Headline corrections: `router.Classify(goal)` returns `run|build|swarm` — **not** `|decompose` (`Decompose` is a fourth `Preset`, opt-in only, excluded from `All()`), a claim three contract files asserted wrongly; `docs/ARCHITECTURE.md` overstated the container egress control as SSRF-proof/IP-layer when `AllowEgressVia` only sets `--network bridge` + `HTTP(S)_PROXY` and no packet filter exists — the proxy is the only *sanctioned* way out, not a hard network wall; metrics refreshed everywhere (120 packages, 375 source + 406 test files, ~89.8K non-test LOC); the six `NILCORE_OPENROUTER_*` / `NILCORE_COMPAT_*` vars documented only in suffix shorthand are now spelled out; `docs/REFERENCE.md` gained an explicit upgrade note for the two settings whose MEANING changed at `573a4df` (`NILCORE_SELFIMPROVE_AUTOAPPROVE=1` was a no-op and now really merges; swarm shards now reach their preset's declared hosts). Roadmap/plan docs keep their plans but now carry accurate SHIPPED / PARTIALLY SHIPPED / NOT-BUILT status and no longer name pruned symbols as live. `CHANGELOG.md` history untouched (append-only). Markdown only — no `.go`, `Makefile` or CI file changed. _Owns:_ `*.md`, `docs/**`. _(Phase 16 — documentation)_ + - **chore(features-review): reconcile shipped-but-inert subsystems, then a full docs pass over the assembled diff.** A features-review sweep found a cluster of built-but-silently-dead paths (several of which reported false green), fixed each with a discriminating test, and then reconciled the docs to the code as it now is. **Verifier integrity:** the `vcache` key now folds in the browser-verify command, `NILCORE_VERIFY_PACKS`, `NILCORE_EVIDENCE_VERIFY`, `NILCORE_EVIDENCE_MAX_AGE` and the sandbox image identity (a behavioral toggle can no longer serve a stale green), and the worktree content hash includes `.nilcore/artifacts` when evidence verification is on; evidence verifiers are now discovered **lazily at Check time** on run/chat/serve/resume (they were built eagerly and so never ran); tiered verify reads only the `go test` leg of a compound command and replicates `-run`/`-skip`; a new boot `validateVerifyEnv` exits 2 on a bad `NILCORE_VERIFY_PACKS`/`NILCORE_EVIDENCE_MAX_AGE`. **Artifact packs:** `code.test_passes` ran `go test -- ''` (which never tested the selected package — a false green) → `go test ''`; `code.build_passes` on an undetectable layout is now Unverifiable, not Pass; `schema_verify` events are actually emitted (the report's SchemaDefects section was permanently empty; `DefectMeta` gained `claim_id`/`reason` + json tags); `software.github_tag_exists` paginates; the audit pack rejects leading-dash patterns. **Swarm:** shards now actually receive their derived egress (an allowlist proxy is stood up and applied per shard box — previously every shard ran `--network none`, so the research preset could never verify green and `--egress-allow` was inert); `--resume` re-seeds skipped/queued/running shards (planned-DAG dependents were being dropped — a false green) and red budget-exhausted shards block a clean converge. **Graduated auto-approval (graapprove) was structurally unreachable:** `AllowBranches:["*"]` never matched slash-y branches (`path.Match`) and trust/rate keyed on per-run-unique scopes — now `*` matches any non-empty scope, and trust + the per-day rate window key on a stable scope **family** (`task/trig-123`→`task/*`, a bare sha→`#commit`); the protected-base floor (main/master/release/trunk/stable/prod*) and `DenyBranches` stay on the **concrete** branch; an empty scope never auto-approves. **Self-improve now really merges:** it had no merge step (it logged `self_edit_merged` and returned `merged=true` while nothing landed) — there is now a real `Flow.Merge` seam, `Run` returns the verified branch, `merged=true` means it actually landed, and new event kinds record the failure modes (`self_edit_merge_unwired`/`self_edit_no_branch`/`self_edit_merge_failed`). **Session / front door:** drive-terminal persist ran on an already-cancelled ctx so conversation state never wrote (now detached — `context.WithoutCancel` + 5s timeout); `Session.Checkpoint` (previously zero callers) is now called on chat exit and in serve's drainShutdown; steer markers (`!`/`/steer`) are stripped before the model sees the turn; memory/lessons (`MemoryContext`) and operator steering (`SteeringContext`) now reach chat/TUI and serve, not just run/watch; `-blast-radius` now fences chat and serve native drives (chat mints ONE shared blast budget for its proxy + sandboxes + gate; a serve-restart-resumed run gets the dollar ceiling); serve's `--webhook` no longer opens a second SQLite handle on the DB serve owns; the serve-embedded flywheel gate is deny-default (was bound to `os.Stdin`); a failed serve drive no longer renders "✓ not verified" over Telegram/Slack. **Security / robustness:** `browsersession.Observation.URL` is scrubbed for typed secrets (an I3 leak into the model prompt AND the append-only log); browseragent irreversible-signal, `router.Classify`, `trust.Classify` and `session.referencesGoal` moved from substring to word-boundary matching; Slack model text is escaped (was ``-injectable), evidence-rich gates clip to Slack's 3000-char cap instead of silently auto-denying, 429/Retry-After is honored, and ws frame length is sanity-checked; Telegram scrubs the token from transport errors and clips long messages; MCP stdio writes are ctx-cancellable (a deadlock), responses size-capped, children reaped, stale resource/prompt wrappers pruned; one malformed SKILL.md no longer disables ALL skills; codeintel + live walks skip symlinks (I4) and vendor dirs (node_modules/vendor/.venv/dist/build), and several tool reads moved to `O_NOFOLLOW`; the termui spinner stop/animate deadlock is fixed (TryLock). **Backends / providers:** an empty-content native reply no longer poisons history and kills the run; Anthropic — a zero-frame clean-EOF stream is a retryable error, server-tool-only (`pause_turn`) turns are preserved, all beta headers collected; OpenAI — web plugin deduped, tool_result error signalled, max_tokens splice fixed; codex/claude-code `digText` matches the real claude-code stream-json (`result` key, `message.content[]`). **Also:** experience projection is rotation-aware (`Rebuild` drops stale keys); autosrc no longer kills a source permanently on a full queue; emit neutralizes ANSI in gate evidence; integrate stops on a failed `merge --abort`; the eventlog torn-tail heal won't drop committed lines; the report writer error-lists as json. **Docs reconciled to the code:** restored the AGENTS.md backend set (a find/replace had corrupted it to "Codex, Codex"), corrected Go 1.25 + dropped the never-adopted `sqlc` in PREREQUISITES, purged dead-symbol references (`impact.Localize`/SBFL, `policy.Gate`/`EgressWith`, `internal/blackboard`, `emit.NopEmitter`, `objective.MarkRun`), corrected the phantom `NILCORE_BROWSER_AGENT`/`NILCORE_DESKTOP_DARWIN` gates to the shipped gating, documented the previously-undocumented env vars in `docs/REFERENCE.md`, refreshed the stale REFERENCE.md metrics/CLI/package inventory, and stated the true Phase-15 status (web search shipped;

The container is rootless, drops capabilities, mounts the rootfs read-only, and defaults to **deny-all egress** (`--network none`). Opening egress (`Container.AllowEgressVia`, `internal/sandbox/sandbox.go:118`) switches the container to `--network bridge` and points `HTTP_PROXY`/`HTTPS_PROXY` at a host-side allowlist proxy (`internal/policy`), which pins the first resolved IP and refuses loopback/link-local/private destinations, so traffic *that transits the proxy* cannot be turned into an SSRF pivot. + +> **Precisely how strong this is.** Enforcement is at the **proxy layer**, honored by proxy-aware clients — **not** at the packet/IP layer. NilCore installs no iptables/nftables egress filter, so once egress is opted in the proxy is the only *sanctioned* way out, not a hard network wall: a command that ignores the proxy env (`curl --noproxy '*'`, a raw socket) reaches the bridge directly. Two things bound this: egress is **off by default** (deny-all, and `web_fetch` is not even advertised), and the namespace backend — the auto-detected default on Landlock-capable Linux — has **no proxy path at all** and is unconditionally deny-all (`CLONE_NEWNET` with no interface, `internal/sandbox/namespace_linux.go`). A packet-layer filter for the container tier is not implemented. **Two Tier-1 backends, one interface (the isolation spectrum).** `sandbox.Sandbox` has two implementations and `sandbox.New` auto-detects between them (override with `-sandbox auto|namespace|container` or `NILCORE_SANDBOX`): - **Container** (`sandbox.Container`, podman/docker) — the portable choice wherever a runtime is present: a separate image rootfs, `--cap-drop=ALL`, `--security-opt no-new-privileges`, a read-only rootfs + tmpfs, the worktree bind-mounted at `/work`, and `--network none`. -- **Namespace** (`sandbox.Namespace`, Linux only) — needs **no runtime, image, or daemon**, so the loop stays sandboxed (I4) on a bare host (a cheap VPS, a Pi, a locked-down CI runner). Each command re-execs the nilcore binary inside fresh user/mount/pid/net/ipc/uts namespaces (mapped to a userns-only root that holds no host capability); the re-exec'd child — `sandbox.MaybeRunInit`, the first call in `main` — sets `no_new_privs`, a **Landlock** domain (read+execute the host toolchain everywhere, read+write **only** the worktree, a `/tmp` scratch, and the usual character devices like `/dev/null`), and a **seccomp-bpf** syscall denylist (P7-T02: EPERMs `mount`/`ptrace`/`kexec`/module-(un)load/`setns`/`unshare`/`chroot`/keyring/clock-set/… and allows the rest — defense-in-depth, applied via `seccomp(2)`+TSYNC and graceful when the kernel lacks it), then `execve`s `/bin/sh -c `. `execve` carries the Landlock domain, `no_new_privs`, and the seccomp filter into the command, so the model's command runs *only after* confinement is in place; the pre-`execve` code is trusted harness code, never model input. `CLONE_NEWNET` with no configured interface is the default-deny-egress equivalent of `--network none`.

The isolation strength runs **Firecracker microVM (strongest; Linux/KVM; future) → container → namespace + Landlock (lightest, most portable)**. `New` prefers the namespace backend wherever the kernel offers Landlock (≥5.13) and unprivileged user namespaces, but is **conservative**: it treats an AppArmor- or sysctl-restricted userns as unsupported and falls back to a container rather than risk an `EPERM` at exec, so `auto` is always correct. The one deliberate trade for needing no runtime: the namespace backend shares the host's filesystem **read-only** (enforced by Landlock) instead of a separate image rootfs. Because the security property (real confinement) is only observable on Linux, a dedicated `sandbox-linux` CI job runs the escape tests with `NILCORE_SANDBOX_MUST_RUN=1` — they fail rather than skip — as the authoritative verifier. **Tier 2 — host-side, worktree-confined (scoped I/O, never arbitrary execution).** The native loop's structured tools run in-process on the host because they are *bounded operations*, not a shell: - `read` / `write` / `edit` / `search` — file I/O confined to the disposable worktree. Confinement is enforced both lexically and after symlink resolution (`filepath.EvalSymlinks` on the worktree root and the target's deepest existing ancestor), and writes use `O_NOFOLLOW` to close the final-component TOCTOU — so an in-tree symlink (`evil -> /etc`) cannot escape. -- `git` — a fixed subcommand set (`status`/`diff`/`add`/`commit`/`log`), never `push`/`reset`/`remote` writes.

The reason Tier 2 is host-side is performance and simplicity (structured edits don't need a container round-trip), and it is *safe* to be host-side precisely because these tools cannot execute arbitrary code and cannot reach outside the worktree. If that confinement ever weakened, the tools would have to move into Tier 1.
