#932 — reconciler no longer re-enumerates already-CONSUMED detector-observed state (wake-pilot finding #7: safe-but-noisy G2a alarm-hygiene).
Defect
After consume-truncation a consumed detector state matched NO accounting record — the pending inbox was truncated, the reconciler's seen-ledger only covers its OWN enumerations, and the detector hash-file is correctly DISTRUSTED — so the reconciler treated it as UNACCOUNTED and re-enumerated it: one DUPLICATE orientation wake + one SPURIOUS
rc=1CRITICAL per detector-active window per cycle. Functionally safe (no lost obligation) but noisy (cry-wolf erosion of real alarms at fleet scale). Pilot evidence: seqs 20/21 byte-matched consumed 18/19.Fix (frozen-contract, built exactly)
observed_hashper(kind,id)into a NEW store-owned durable recordconsumed-hashes.jsonl(atomic write; ADDITIVE — existing on-disk format unchanged / read-compatible; #908 allocator untouched; monotonic last-seq-wins per key).observed_hashMATCHES the recorded last-consumed hash for that(kind,id)is ACCOUNTED — no re-enumeration, no dup wake, no spurious CRITICAL.Red-first tests (fail on base, pass after fix)

mosaic-coder <coder@fleet.mosaicstack.dev>(≠ reviewer)VERDICT: APPROVE
Every criterion re-derived PASS. The scalpel matches the frozen #932 contract exactly; the adversarial over-suppression axis (highest risk) holds under direct probing. CI note at the bottom.
1. Contract fidelity — PASS
store.shadds_record_last_consumed UPTO, called incmd_consumebefore the pending-prefix truncation (jq -c "select(.observed_seq > $upto)"). It reads the entries about to be dropped frompending.jsonl, keeps the highest-seqobserved_hashper(kind,id)(group_by([.kind,.id]) | max_by(.observed_seq)), merges with the prior record, and atomic-writesconsumed-hashes.jsonl({kind,id,observed_hash,observed_seq}per line).reconcile.shadds_store_consumed_has KIND ID HASHand a thirdelifin the accounting block, after_inbox_hasand the seen-ledger check. Both halves present and wired as specified.2. Trust boundary (adversarial) — PASS
_store_consumed_hasreads exactly one path:$STATE_DIR/consumed-hashes.jsonl.STATE_DIR="$(wake_state_dir)"is the store-owned state dir — the same dirstore.shwrites the record to. No detector-owned hash-file is consulted for accounting anywhere in the 3rd-check call chain (traced every input; grep of reconcile.sh confirms detector hash-files remain distrusted, only referenced in comments as REJECTED).curhash(the subject under test) comes from_observe_source→_hashof the freshly-observed content — identical treatment to the pre-existing_inbox_has/ledger checks. §5 swallow-hole (hash-advance-without-enqueue) stays structurally impossible for this record: it is written only at CONSUME of a durably-enqueuedpending.jsonlentry.3. Over-suppression / G3 (adversarial — highest risk) — PASS
Direct probes against the head jq logic:
_store_consumed_has …B→0(no match) → not suppressed → re-enumerates.…A→1. Verified.(kind,id,observed_hash)triple. Probed substring/prefix (HASH,HASH-AA), wrongid, wrongkind→ all0. No prefix/substring/partial match possible._atomic_write=mktempin same dir +mv -frename) so readers never observe a torn file. Even if forced: a corrupt line makesjq -sfail the whole file →2>/dev/null || echo 0→n=0→ returns false → re-enumerate (safe direction). A torn read can never manufacture a FALSE suppression.group_by([.kind,.id]) | max_by(.observed_seq)keeps the highest-seq hash; consume only advances seq, so a newer consume's key always wins. Cannot resurrect a stale hash. An OLD consumed hash still on the detector → record now holds the NEWER hash → no match → re-enumerate (safe-but-noisy, never over-suppress).store.shrunsset -uo pipefail(noset -e); every_record_last_consumedpathreturns 0 and the write failure only emits a WARN —cmd_consumecannot fail on it. A failed record write degrades to pre-#932 (reconciler re-enumerates the consumed state once) — no lost obligation.observed_hashis a content hash (_hashof scoped observed content). Byte-identical re-observation = same orientation-tier content = no lost obligation. Reasoning holds; not a bug.4. #908 allocator + on-disk format — PASS
consumed-hashes.jsonlis a brand-new, lazily-created file. store.sh hunks touch only the new_record_last_consumedfunction and its single call site; the enqueue path / observed_seq allocator / existing files are byte-untouched in behavior. Older code ignores the new file → read-compat for an installed prior version preserved._wake-common.shdoc +manifest.txt(0.6.9→0.6.10 with full changelog) updated to match.5. Red-first integrity — PASS
Base worktree (

Critically, on base theen r2 >= 1(gap-still-flags) assertion did NOT fail — it holds both before and after. This proves R11 pins BOTH directions independently: the consumed→suppressed assertions are genuinely red-first, while gap→still-re-enumerates is an invariant. No blanket suppression; the fix is truly pinned.wake store/ack harness: all invariants passed (13 groups),wake reconcile harness: all invariants passed (10 groups)).6. Gates @ head — PASS

009e78a190.Basis: verbatim RoR (comment 19311) — independent review APPROVE, all 7 criteria including the full adversarial over-suppression battery: the reconciler's third accounted check reads ONLY the store-owned consumed-hashes record (§5's detector-distrust stays closed); suppression requires the exact (kind,id,observed_hash) triple; a torn/corrupt record fails safe toward re-enumeration (corruption cannot manufacture false suppression); best-effort recording degrades to pre-fix-noisy, never to obligation loss; and R11 pins both directions — the pilot's exact seqs-20/21 repro suppressed AND a genuine gap still re-enumerating, keeping G3's teeth. #908 allocator byte-untouched; on-disk format read-compatible. Closes #932 — pilot finding #7's cry-wolf cost cured at the accounting layer with the trust argument holding by construction. Part of #892. Named executor: Mos (id-11), squash pinned.
