+# 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.
+

+| Who | Codex, temporary migration-boundary and retirement-contract custodian |
+| When | 2026-08-22–23 |
+| Where the work lived | `state-hub`, its live work records and inbox, and the Hall of Helix |

+| Token count | Not exposed by the harness |
+
+## 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.
