Cross-family review (Codex CLI 0.155.1, gpt-6-astra, model_reasoning_effort=max, read-only sandbox), 2026-09-26. Run by the workstation coordinator against a clean checkout of main after merge. Supported findings get a repair PR (one repair round; residuals recorded).

DEFECTS FOUND

• high | results-20260925.json:238 | Most of the 89 checks retain only the custom analyzer’s booleans. Native responses, handoff state and process receipts are neither published nor hash-bound, preventing independent verification of the native_cli_e2e claim. | Retain sanitized per-phase inputs, responses and execution receipts; classify the custom fixture as local integration and distinguish it from unchanged upstream acceptance.

• medium | pr-292.meta:25 | The claimed “live quality” gate coverage contradicts the gate’s requirements: live-store policy, scoped retrieval quality and evaluated learning remain untested and are explicitly excluded by this blueprint. | Remove the gate-closure claim from the PR body and PREREGISTRATION.md:19; describe only the isolated lifecycle properties exercised.

• medium | analyze.py:38 | Missing hits becomes an empty successful search. Replacing four restart query responses with {} still produces 17/17 passing checks, falsely confirming deletion and sweep persistence. | Require a list-valued hits field and reject malformed responses before evaluating emptiness.

• medium | analyze.py:89 | Any integer-coded error satisfies the scope-conflict check, including "storage unavailable", although preregistration requires a message identifying the conflict. Similarly, a method-not-found error passes the deleted-page check. | Validate each rejection’s expected semantics, including the conflict or missing-page message, against the tested version.

• medium | analyze.py:91 | The multi-project check accepts three copies of alpha’s hit while returning nothing from beta or gamma: it checks only count and identical paths. | Compare distinct returned page IDs with the IDs written to alpha, beta and gamma, and verify their scopes.

• medium | exercise.py:237 | Sweep verification checks search visibility only. Swept pages could remain directly readable while every check passes, contradicting the claimed removal from the MCP surface. | Assert that direct reads of both swept paths fail immediately after sweeping and after restart.

• medium | PREREGISTRATION.md:268 | The failed attempt’s output was discarded, violating the evidence-retention policy. The results also mark the amended preregistration hash as recorded “before any run,” despite documenting its post-failure correction. | Preserve failed-attempt receipts and original/amended preregistrations; distinguish the original freeze from the corrected rerun.

• low | results-20260925.json:5 | observed_at_utc is 20:28Z, but the completed TTL trials cross expirations at 20:32:08Z and 20:32:16Z. The observation timestamp predates the reported observations. | Derive observation and per-phase timestamps from retained execution receipts.

Correction (2026-09-26). Parts of this description are withdrawn or corrected by #330. Sources: blueprints/memory-lifecycle-v2/results-20260926.json, the corrections list in blueprints/memory-lifecycle-v2/results-20260925.json, and blueprints/memory-lifecycle-v2/history/attempts-20260925.json.

1. Withdrawn: "the "live quality" half of the memory-lifecycle gate in catalogs/us-equities/convergence-review.json". The run used disposable stores only: a real-time TTL crossing, scoped routing across 4 projects in 2 workspaces, and a restart. The gate's remaining requirements (live-store policy, scoped retrieval quality and evaluated learning) were not exercised, and the gate stays open.
2. Corrected: the evidence class is local_integration (a locally authored fixture that drives the official binaries over stdio MCP), not native_proven. ai-memory's own test suites are recorded separately in memory-lifecycle-v2 repairs: ai-memory's own upstream suites at v2.3.2/v2.4.0/v2.4.1, repaired fixture (GPT-6 reviewed) #330.
3. Withdrawn: "it qualifies 2.4.0's lifecycle semantics as identical to 2.3.2's on this suite", and the 72/72 and 17/17 results (89/89 in the title) as acceptance. The merged analyzer still scored 72/72 and 17/17 after each of four mutations of the retained responses: the four restart queries answered {}, "storage unavailable" in place of the scope-conflict rejection, -32601 in place of the deleted-page error, and three copies of alpha's hit as the scopes[] result. Re-checked with the repaired rules, the retained responses pass 95 of 95 comparable checks on both binaries (history/recheck-20260925.json); the acceptance evidence is now the 2026-09-26 rerun.
4. Corrected: "PREREGISTRATION.md was written before any run", "Two harness defects were found and fixed before any complete result existed" and "both are disclosed in it with the superseded preregistration hash". 2.3.2 had five attempts and 2.4.0 two. The first three 2.3.2 attempts failed: at 20:21:37Z the phase-post call-count guard (15 against 16 calls); at 20:23:08Z scope tuples sent as (project, workspace); at 20:27:16Z a complete run in which 8 of 72 phase-pre checks failed, after which analyze.py was changed to read global_hits. Only the call-count fix is disclosed in PREREGISTRATION.md (the correction note in its section 4), and the superseded hash is in the preregistration note of results-20260925.json, not in PREREGISTRATION.md. The scope-tuple swap appears only in this description, in no file of this PR, and the third failure and the analyzer change were not disclosed at all. Every attempt directory except the final 20:32Z pair was deleted. The committed PREREGISTRATION.md is the amended text (sha256 fb82e0aa…, recorded 20:23:01Z, after the first failed attempt and before the second); the original (ca81e9b4…, recorded 20:17:18Z, before any run) is kept byte-identical under history/.

The repaired rerun in #330 is local integration evidence: ai-memory 2.3.2, 2.4.0 and 2.4.1 each passed 82/82 phase-pre and 19/19 phase-post checks on their first attempt. ai-memory's own cargo test --workspace --all-targets passed at v2.3.2 (3,357 passed, 0 failed, 11 ignored), v2.4.0 (3,515 / 0 / 14) and v2.4.1 (3,615 / 0 / 14); v2.4.1's cargo test --workspace --doc selected no tests and is recorded as untested.
