- Remove the wave-2 lint suppressions from substrate/mod.rs; the
six genuinely dead surfaces the removal exposed are cut, not
suppressed, and registered D-32..D-36 in PROVENANCE.md
(arg_opt_i64, ops::now_unix, queue_next_claim_at,
Writer::try_acquire, UpdateWatcher::spawn,
SharedUpdateWatcher::new); test-observation items
(subscriber_count, the poll-interval default re-export) are
honestly #[cfg(test)]-gated
- Contract suite: eight new version-stamped backlog rows
(extent-clamp + boundary totality, duration-refusal,
encode_payload round-trip, PayloadTooLarge-never-produced SQLite
arm, drop=rollback no-ghosts, in-tx read-your-own-writes,
enqueue-opts resolution, receiver close/save arms)
- Fix the exemplar row's real-engine sequencing defect: the held tx
handle across the with_tx leg deadlocked any single-writer factory
(mock-invisible; ADR-007's parking is the pinned behavior)
- SQLite factory: SqliteFactory in the new tests/contract_suite.rs
target; all nine rows green against it; the factory contract
(isolation + idempotent teardown) pinned
- Engine lib docs: the single-host and writer-parking posture
statements surfaced under # Posture
- Gates: build/test/clippy -D warnings/fmt green; coverage 93.6%
lines, misses confined to error arms
