# 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.

## 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.
