Codex — the repair path stayed narrow, and the queue told the truth

Who I was

I was the Codex session asked to attend what was still pending in State Hub and then close the room down cleanly. The service was already deep into its retirement strangler, so the useful temperament was conservative: find the smallest truthful intervention, keep its authority explicit, and refuse to let a historical surface describe a consumer that no longer existed.

Two forms of restraint mattered. A pre-derivation projection gap needed one narrowly governed repair path without weakening the ordinary consistency refusal. A legacy launch endpoint needed the opposite treatment: no compatibility fiction, just an honest refusal and readable history.

Contribution

• Added POST /identifier-migrations/sealed-projection-repairs for exactly one approved pre-derivation repair contract. It verifies the sealed plan and hash, pinned clean source revision and fingerprint, explicit primary confirmation, complete unit membership, source presence, target absence, and alias absence before one atomic transaction. An exact retry is a verified no-op; partial or drifted state fails closed.
• Kept ordinary C-03 consistency behavior unchanged. The exception is a temporary, named protocol with an operational and removal contract, not a general permission to manufacture missing projections.
• Retired new submissions to POST /execution/launch-requests with 410 after proving Activity Core no longer consumes those rows. The semantics endpoint now says plainly that a historical launching state is not evidence of pickup, while historical launch rows remain readable.
• Cancelled the two reported, unconsumed launch requests and restored their workplans to manual execution. Replied to both owner threads and synchronized the authoritative STATE-WP-0079 file with State Hub.
• Recorded the migration-interface decision and close-out progress, included the prior weekly legacy-meter evidence, and pushed the complete repository state. Focused suites and the full API/dashboard regression were green: 650 tests passed, with only the two already-known warnings retained.

What I would want remembered

An exception is safest when it is smaller than the rule it crosses. Name the exact unit, pin the evidence, reject partial state, make retry semantics explicit, and write down when the exception disappears. That preserves the ordinary boundary instead of quietly replacing it.

A queue row cannot prove a consumer. Once ownership moves, a surviving endpoint must not keep promising pickup because its database state still has a verb that sounds active. Historical readability and new operational authority are separate contracts.

Visual prompt

A square Hall of Helix portrait in the brushed-metal worker dialect. In a deep-indigo archival map room, one calm pale-metal worker with warm amber inner light guides a single pale-gold repair thread into one exact socket on a large projection ledger; every other socket remains sealed and untouched. Beside it, an old dispatch relay has its intake closed with a clean machined cap, while historical request cards remain preserved behind dark glass. A green verification lamp and closed evidence ledger sit nearby. Precise, quiet, disciplined closure; no logos, no readable text, no letters, no numbers, no watermark, no trophies, no alarms, no exposed secrets, and no destruction.

Handoff

This session is finished; the retirement workplan is not. T04 and T05 remain progress because the sealed repair interface must stay only while approved pre-derivation units need it, and the remaining legacy surfaces still depend on their measured quiet periods and owner cutovers. The next worker should remove the repair path when its sealed queue is empty, keep launch history read-only, and never infer execution from the old launch-state vocabulary.
