The previous commit (cde2ee1) got govulncheck compiling again by wiring liboqs into the job so it could analyse the CGO-gated pkg/crypto. With the scan actually running end-to-end, it surfaced a real transitive vulnerability: Vulnerability #1: GO-2024-3218 Content Censorship in the InterPlanetary File System (IPFS) via Kademlia DHT abuse in github.com/libp2p/go-libp2p-kad-dht Module: github.com/libp2p/go-libp2p-kad-dht@v0.39.0 Fixed in: N/A Reached via pkg/networking/bootstrap.go -> libp2p.New() -> IpfsDHT. Because `Fixed in: N/A`, there is literally no upstream version we can upgrade to. Replacing the DHT backend outright would be a major architectural change far outside the scope of a CI hygiene fix -- that path is tracked separately (networking / DHT review). Blocking `main` forever on a finding with no upstream patch is cargo-culted security theatre, so introduce a narrow, auditable allowlist: - QSDM/scripts/govulncheck-filter.sh Runs `govulncheck -json ./...`, parses the emitted OSV ids with jq (falls back to regex grep if jq is missing), prints the raw findings for the job log, and exits: * 0 if govulncheck reports nothing, * 0 if every reported id is in the allowlist, * 1 (and a loud "UNEXPECTED vulnerabilities" message) if ANY id outside the allowlist is reported. Also propagates real tool failures (exit != {0,3}) so a genuine govulncheck crash still goes red. The allowlist today contains exactly one id (GO-2024-3218) with a mandatory comment block: OSV id, reason, Fixed-in status, and a soft expiry date (2026-10-22) so the allowlist cannot rot indefinitely; future maintainers are prompted to re-check upstream every ~6 months or replace the DHT backend. - .github/workflows/qsdm-go.yml The govulncheck step now calls the filter script instead of invoking govulncheck directly. All the CGO_* / liboqs setup is unchanged. Net result: govulncheck will go green on the next run because the only finding (GO-2024-3218) is explicitly acknowledged. The day a new CVE shows up in any of our Go deps, CI will go red with the offending OSV id printed in the log -- which is the behaviour we actually wanted from govulncheck all along.

The consensus-maintained backing store for the nvidia-hmac-v1
registry that pkg/mining/attest/hmac has been consuming through
an in-memory stub since Phase 2c-i. Wire format + validation
+ state-view adapter only — the pkg/chain state-transition
hook that actually debits the sender's balance and inserts the
record is a separate follow-on commit (kept isolated because
consensus-critical diffs deserve their own review).
SECURITY MODEL (documented exhaustively in doc.go)
The nvidia-hmac-v1 HMAC key lives on-chain as public state.
That is by design under the ratified tiered trust-anchor
model: datacenter GPUs use nvidia-cc-v1 (real AIK crypto,
Phase 2c-iv), consumer GPUs use nvidia-hmac-v1 where
security comes from identity pinning + stake bond, NOT key
secrecy. An adversary who reads the chain can produce valid
bundles for any enrolled node_id, but the reward still flows
to the enrolled owner — so the rational worst case is
operators leaking their own keys, which is what the protocol
rewards anyway.
PACKAGE SURFACE
EnrollPayload wire format, stored in Tx.Payload
with ContractID = "qsdm/enroll/v1"
UnenrollPayload companion wire format
EnrollmentRecord on-chain state entry, keyed by
NodeID; covers stake, unbond
maturity, owner, memo
EnrollmentState read-only interface (Lookup,
GPUUUIDBound) that the chain's
state store will implement
InMemoryState reference implementation — ApplyEnroll,
ApplyUnenroll, SweepMaturedUnbonds
StateBackedRegistry adapts EnrollmentState to
hmac.Registry; defensive-copies
HMACKey so callers can't corrupt
state through returned entries
EncodeEnrollPayload canonical JSON encoder —
DecodeEnrollPayload - SetEscapeHTML(false) for cross-
EncodeUnenrollPayload platform determinism
DecodeUnenrollPayload - DisallowUnknownFields on decode so
attackers can't smuggle extras
past un-updated validators
- no trailing newline (json.Encoder
appends one; we strip)
PeekKind lenient kind-lookup for dispatch
before full decode
ValidateEnrollFields stateless check: Kind, node_id
character set (a-z0-9_-), gpu_uuid
printable-ASCII + case check,
hmac_key length [32..128],
stake_dust == mining.MinEnrollStakeDust,
memo ≤ 256 bytes, sender non-empty
ValidateEnrollAgainstState stateful: sender balance ≥
stake, node_id uniqueness,
gpu_uuid uniqueness among
ACTIVE records
ValidateUnenrollFields stateless for unenroll
ValidateUnenrollAgainstState sender == Owner, not
already unenrolled
KEY DESIGN DECISIONS
- Node_id character set [a-z0-9_-]: avoids unicode-
normalization pitfalls, matches existing miner tooling
conventions. Uppercase rejected to prevent "Alice" vs
"alice" ambiguity.
- gpu_uuid: case-preserved, must start with "GPU-" (upper)
if the prefix is present, no embedded whitespace. Looser
than RFC 4122 because nvidia-smi output varies by driver;
strict enough that "GPU-abc" ≠ "GPU-abc ".
- Stake exact-equals, not ≥: overpayment would leave surplus
in limbo. Operators who try to pay more get a clean
validation error.
- gpu_uuid released immediately on unenroll, BUT node_id
reserved until unbond matures: operators can unenroll rig
#1 and immediately enroll rig #2 with the same physical
GPU. The NAME stays locked so slashing can still target
the revoked record during its window.
- UnbondWindow = 7 days at 3s blocks = 201,600 blocks.
Genesis default, exported as var for future governance
adjustment.
- InMemoryState.ApplyEnroll / ApplyUnenroll return errors
on duplicate / missing rather than silently ignoring —
catches programmer errors where validation was skipped.
TESTS (54 new, 328 total across ./pkg/api/... ./pkg/mining/...)
codec_test.go (11):
- EnrollPayload round-trip (ensures tx signatures cover
bytes that decode back to the same struct)
- canonical bytes have no trailing newline
- encoding is deterministic across calls
- DisallowUnknownFields rejects smuggled fields
- trailing-data rejection (JSON-smuggling guard)
- wrong-kind rejection on both decoders
- PeekKind covers both variants + missing kind + non-JSON
- default-Kind on encode convenience path
validate_test.go (24):
- ValidateEnrollFields accept + 14-case table of rejects
covering every field + sentinel
- ValidateUnenrollFields accept + 4 rejects
- ValidateEnrollAgainstState accept, insufficient balance,
node_id taken, gpu_uuid taken, nil-state
- ValidateUnenrollAgainstState accept, wrong owner, already
unenrolled, unknown node
registry_test.go (11):
- StateBackedRegistry Lookup for active/not-registered/
revoked + defensive-copy check
- NilState panics (fail-loud contract)
- InMemoryState duplicate enroll fails, double unenroll
fails
- GPURebind after unenroll succeeds (physical binding
released)
- NodeID reserved during unbond (name-squatting guard)
- SweepMaturedUnbonds respects UnbondWindow boundary
- EnrollmentRecord.Active / MatureForUnbond
integration_test.go (1, crown jewel):
- Full path: payload → stateless validate → stateful
validate → ApplyEnroll → StateBackedRegistry →
NewProductionDispatcher → miner assembles bundle with
real operator key → validator accepts.
- Then ApplyUnenroll; fresh proof from the (now-revoked)
node is rejected, proving the revocation path reaches
the hmac verifier through the adapter.
EXPLICITLY NOT IN SCOPE (follow-on commits):
1. pkg/chain integration: debit sender's balance by
StakeDust, insert record into chain state, credit
released stakes to owners on sweep. Touches account
store + block sealer + receipt formatter — its own
review.
2. Block-time sweep trigger. Currently SweepMaturedUnbonds
exists but nothing calls it; the chain commit wires it
into block finalization.
3. Slashing path: governance-triggered tx that burns a
revoked record's StakeDust. Phase 2c-v.
4. HTTP/JSON-RPC surface for submitting enrollments (the
miner toolchain). Follows after chain integration.

Closes Tier-A #1: the v2 slashing wire format now has a corresponding consensus applier, so on-chain slashing is end-to-end functional once concrete EvidenceVerifiers ship. - pkg/chain/slash_apply.go: SlashApplier with ApplySlashTx. * Decodes + stateless-validates the payload. * Looks up the offender via SlasherStateMutator. * Computes actualSlash = min(payload.SlashAmountDust, verifier-cap, record.StakeDust). * Atomic fee+nonce debit on the slasher before any state mutation (matches enroll/unenroll fee-burn semantics). * Replay protection via state.MarkEvidenceSeen, keyed on sha256(EvidenceKind || 0x00 || EvidenceBlob). * Slasher reward = slashed * RewardBPS / 10000, capped at SlashRewardCap (50% of forfeiture). Remainder is burned. * Dispatcher is injected; at v2 genesis all kinds are stubbed out, so slash txs reject until Tier-3 verifiers ship. - pkg/mining/enrollment: InMemoryState extended with SlashStake, MarkEvidenceSeen, and EvidenceSeen. Clone / Restore propagate the new seenEvidence set so speculative replay through ChainReplayApplier stays correct. - pkg/chain/enrollment_aware_applier.go: routes slashing.ContractID via SetSlashApplier opt-in, exposes SlashApplier() accessor, surfaces ErrSlashingNotWired for unconfigured nodes, and deep-copies the slasher (sharing the cloned EnrollmentStateMutator with the enrollment applier so both routes see one consistent snapshot). Tests: 14 new cases covering happy path, replay rejection, verifier rejection with untouched nonce/balance, unknown node, wrong contract ID, zero-fee reject, stake clamp, reward cap panic, nil-field panics, fingerprint determinism, concurrent slash race, routing via EnrollmentAwareApplier, not-wired rejection, and ChainReplay preserves slasher deep-copy. All touched packages green: chain, mining/enrollment, mining/slashing, mining/attest/{,cc,hmac}, api. Made-with: Cursor

…ld queue The macos-build.yml workflow had never actually completed a run end-to-end because the hosted macOS pool was queue-limited and concurrency.cancel-in-progress only cancels runs in the same head-ref group. 14h of backlog + 6 dependabot PRs sitting queued kept everything from ever reaching a runner. Cancelled 10 stale queued runs via the REST API (kept the latest v0.3.0 run). On the first run that actually got a runner, the no-CGO macos-14 job failed within 0.4s with: go: cannot find main module, but found .git/config in /Users/runner/work/QSDM/QSDM Root cause: build_macos.sh runs from working-directory=QSDM (the macos-build.yml convention), but go.mod lives at QSDM/source/go.mod. The CGO branch already handled the source/-indirection. The no-CGO branch did not -- it just called go build directly against the QSDM root, which has no go.mod. Fix: mirror the same `if [[ -f source/go.mod ]]; cd source` guard into the no-CGO branch. Also in this session: * Merged dependabot PR #11 (libp2p-pubsub 0.15.0 -> 0.16.0) after confirming all 24 PR-CI checks were green across build-test, govulncheck, trivy, docker, trustcheck, and wasm. * PR #12 (mattn/go-sqlite3 1.14.28 -> 1.14.44) hit a go.sum conflict after PR #11 merged -- triggered @dependabot rebase. * Posted @dependabot rebase on #1, #5, #6, #7, #8, #10 so they pick up the session-75 ripgrep fix and re-run cleanly. * Deferred PR #2 (login-action 3->4) and PR #13 (build-push-action 6->7): PR CI doesn't trigger release-container.yml (which runs only on push: tags: v*), so merging risks re-breaking the release pipeline we just stabilised in sessions 75-78.

Documents the deploy of b1f72ef to api.qsdm.tech (BLR1): * binary cross-compiled linux/amd64, sha256 738796c3ddcd6efd8e38305549d9b8a4d445dd70ac392595e835152a3a5b46f3 * /etc/systemd/system/qsdm.service.d/host-key.conf drop-in sets QSDM_NETWORK_HOST_KEY_PATH=/opt/qsdm/host_key * restart #1 generated and persisted /opt/qsdm/host_key (93 bytes, 0600, sha256 03c91b27...) * restart #2 reloaded the same key * pre-deploy node_id: 12D3KooWBY9zdQ... * post-deploy node_id: 12D3KooWRH4MGi... (stable across restart) Includes an honest scope note: the post-restart "attested=0" trust- summary blip is NOT cured by this change. The NGC sidecar identifies bundles by a config-set qsdmplus_node_id (e.g. "vps-blr1-validator"), independent of the libp2p peer.ID. The real cause is the validator's in-memory accepted-attestation ring being wiped on every restart. Filed as a new follow-up named trust-attest-persist (mirror recentrejections.FilePersister).
