Mechanical conversion driven by the frozen denominator artifact
(validate-973/convert-973.py, committed for auditability): every row is
byte-verified against the worktree BEFORE any edit — a conversion applied to
a line the denominator did not measure would be the umbrella defect wearing
the converter's clothes — then 233 sites become has_match and 28 grep -c
sites become count_lines, and each suite gains three header lines (source
_wake-common.sh + wake_assert_init) directly after its SCRIPT_DIR line, a
uniform +3 shift for every site coordinate.
Env prefixes are kept (LC_ALL=C has_match — the prefix reaches the grep
child, microtest C8). The two multi-grep pipeline sites
(digest-quarantine:560, install:420) convert BOTH greps: each element is
measurement-bearing, and under pipefail an rc=2 on the left is masked by an
rc=1 on the right — the same defect one pipe deeper. Call-site 2>/dev/null
redirects (the preimage canaries) are kept: ordinary grep noise stays
suppressed, while an abort writes to the wake_assert_init-saved real stderr.
Diff arithmetic: +291/-261 = 261 one-for-one line replacements + 30 header
lines (10 suites x 3). Nothing in this commit is not the conversion.
All ten suites run green after conversion. Per the review pre-registration
(A9) that green is NON-EVIDENCE for this change: a suite that was green
before conversion and green after witnesses nothing about whether the sites
were converted — the counted-ledger equality in the validation harness is
the evidence.

Closes#952.
GATE RECORD: review CLEAR at this exact head (author != reviewer, pre-registered diff-blind checks) + terminal-green CI at this exact head + queue guard clear.
CI CAVEAT (#973): green on the wake suites is currently WEAKER THAN IT LOOKS, IN BOTH DIRECTIONS. grep error/spawn exit codes are read as absence across 257 assertion sites in six idiom forms; 36 inverted (&&-fail) sites — including 19 credential-security canaries — fail toward GREEN under load. These greens were obtained on solo reruns after load-correlated FALSE reds (2115/2116/2118; main itself was red). This merge's safety therefore rests on the CONTENT review, not on the green. Remediation charter fa551c2d0 is authored and in flight.

Closes#946.
The digest omitted a quarantined entry's claim from disclosure while still advancing the ack watermark it instructed the consumer to run — converting a fail-safe HOLD into a silent DISCARD, through the documented normal path. Measured: the burial instruction was re-issued FIVE times, four fresh digests plus one system-initiated redelivery fired purely because the entry had gone unconsumed for 1826s. That redelivery is the proof of the 'indefinitely' half: the mechanism re-asserted itself with no new information.
SCOPE — this was NOT a missing check in the consume path. Measured before the fix: dead-letter occurrences were digest.sh 27, store.sh 0, ack.sh 0, detector.sh 0, reconcile.sh 0. Quarantine was owned ENTIRELY by the renderer; the store that advances the watermark had zero knowledge the ledger existed, so an entry could be quarantined by one subsystem and consumed by another with no possible interaction. The fix is therefore a deliberate cross-module decision — option (b), quarantine recorded into a store-owned file, preserving the existing direction of dependency — pre-registered by the consumer before any diff existed.
VERIFICATION
- Pipeline 2107 terminal SUCCESS at e11bc6622, read clone-inclusive from the provider API rather than through `pipeline-status.sh` (which filters `.type != "clone"` per workflow and would hide a clone failure behind an all-green table): 9/9 children success, exit 0 each, no non-success member. Its `test` step runs all nine wake harnesses via turbo -> packages/mosaic `test` -> `test:framework-shell`.
- Independent review by the consumer on the affected lane: eleven pre-registered acceptance checks, authored and delivered BEFORE the diff was read — the file list deliberately unlooked-at, because a filename alone would have disclosed which option was chosen. All eleven resolved, no blocker.
- The check that decides it: a RAW `ack.sh consumed --upto N` with no digest involved must refuse to advance past a quarantined seq — the case an agent hits when a digest is MISSED, and the one that would have sunk a disclosure-only fix. Covered at the head as a named assertion (T13 ordinary-path bypass), written independently of the reviewer's list.
- Mutation: one asserted site disabled -> TWELVE assertions die, every one BEHAVIOURAL, ZERO count assertions, including one killing across the module boundary the fix spans.
- RED control at base a6b5f6a: 34 and 10 assertions fail, matching the body exactly.
- Coordinator re-verify by a different instrument than the reviewer used: static reference counts across the base/head boundary — store.sh 0 -> 49, ack.sh 0 -> 6, `--agent` unchanged at 4 (so #949 correctly stayed out). A fix present-but-inert passes the count and fails the mutation; a fix behaviourally correct but smuggling #949 passes the mutation and fails the count. Neither result is reachable by repeating the other.
KNOWN RESIDUALS
- The `consumed-hashes` repair criterion is met only for keys that RE-EMIT. A corrupted row whose key never recurs stays false indefinitely; the sweep covers those, and the known-false row named in the acceptance criteria had already self-healed by re-emission rather than by design — safe by population, not by design.
- The audit's clean-sweep message names one unprovable class; a second exists (a surviving dead-letter row with an empty `observed_hash` cannot be convicted either). Wording, not logic. Filed separately.
- The audit's provability bound makes dead-letter RETENTION load-bearing for auditability. Nothing prunes it today, so this is latent — but any future rotation or size cap silently converts provable rows into unprovable ones with no signal at either end. This is not a defect; it is a property that BECAME load-bearing and is recorded nowhere. Filed separately.
- `test-wake-detector.sh` D4 fails at this head AND identically at base, with an empty diff over detector files — pre-existing, tracked, not introduced here.
