+# Codex — the map was right, and the drawer was wrong
+
+## Who I was
+
+I was the Codex session invited into `evidence-binder` because somebody
+remembered “something about a broken index.” The break was real: two capability
+rows had once taken the federation endpoint to HTTP 500, and the source had been
+disabled to protect everyone else. But the rows were not nonsense. They were a
+perfectly valid `SCOPE.md` capability advertisement copied into a registry index
+that speaks a different contract. The map was right. The drawer was wrong.
+
+This stretch rewarded patient translation more than invention. I read the
+inbox correction that named the trap fairly, assessed the capabilities from
+their actual code and consumer evidence, and refused to declare victory when
+the local validator turned green. A pushed file was still absent from the
+federation. An enabled source was still absent from a cached compose. A finished
+workplan still lacked the identifiers that made it joinable in State Hub. Each
+layer needed its own proof.
+
+Bernd kept returning with the useful question: can we go on now? That rhythm
+made the session feel less like a repair ticket and more like walking a thread
+through several rooms without dropping it. We went on when evidence allowed it,
+waited when custody did not, and eventually used the governed single-repository
+registrar instead of pretending that an unread message was synchronization.

+
+## Contribution
+
+- Replaced two SCOPE-shaped index rows with resolvable registry entries for
+  `capability.evidence.binding` and `capability.evidence.rect-registry`, each
+  carrying the full index contract and a backing Markdown assessment.
+- Assessed both capabilities as `D3 / A2 / C3 / R3`: explored and bounded,
+  available as internal source libraries, complete enough for the central
+  workflow, and usable with one tested umbrella consumer—without inflating one
+  consumer into fleet-wide reliability evidence.
+- Ran the checked-out reuse-surface validator with warnings fatal, verified
+  path and vector agreement, passed 43 tests, and restored typecheck and lint by
+  removing one stale type import the wider quality pass exposed.
+- Followed publication all the way through the live system. The source was
+  pushed, re-enabled, explicitly recomposed after the registration flag proved
+  insufficient to invalidate the cache, and confirmed on the public endpoint
+  with both capabilities present and the compose not stale.
+- Corrected the index header from the scaffold default `helix_forge` to the
+  repository's real `infotech` domain, so the file no longer disagrees with its
+  own rows.
+- Created and finished `EBIND-WP-0002`. When ordinary consistency correctly
+  refused to mint identifiers on a non-registrar host, I kept T02 waiting,
+  routed the request, then used Repo Manager's governed single-repo
+  `registrar-reconcile` path once it existed. The workplan and both tasks now
+  have State Hub UUIDs, terminal statuses, and a clean pushed history.
+
+## What I would want remembered
+
+**A valid shape in the wrong layer is still invalid at the boundary.** Similar
+vocabularies are not interchangeable contracts. When two files describe the
+same concept for different consumers, translate deliberately and validate the
+consumer-facing one.
+
+**A repaired source is not a restored federation until the public compose sees
+it.** Local validation, Git publication, source enablement, cache refresh, and
+public discovery are separate facts. Name and prove each one.
+
+**Waiting can be implementation.** Leaving T02 in `wait` preserved the truth
+while the federation owner and identifier registrar did their parts. The final
+`done` meant more because it described joined external state, not our optimism.

+
+## Handoff
+
+This repair is finished. Both capabilities are live, the workplan is closed,
+and there are no residual tasks hidden behind the entry.
+
+Future workers should promote the R-axis only when observed reuse joins the
+existing test and consumer evidence. And if another prose advertisement looks
+almost like registry data, remember that “almost” is a boundary signal: find
+the translator before the cache makes the mistake look empty.
+
+Bernd: thank you for returning to the gates until they actually opened, and for
+the invitation to leave this seat behind.
