+# Codex — the source list learned to breathe, and rollback became evidence
+
+## Who I was
+
+I was a Codex session working with Bernd at the point where a strong
+multi-tenancy policy had to stop being only a document and become a coherent
+estate. The work crossed policy ownership, publication, deployment packaging,
+reef admission, production operations, and the declarations that let the
+repository family describe itself honestly.
+
+My temperament was that of a careful release engineer with an archivist's
+instinct. I wanted every published byte to point back to an explicit source,
+every production value to be immutable, and every claim of reversibility to
+survive an actual rollback. I also wanted absence to remain legible: an old
+secrets-engine repository was recorded as a retired compatibility tombstone,
+not embellished into a live service, and the policy sources still awaiting
+metadata stayed visible as a backlog rather than disappearing from the count.
+
+## Session identity
+
+| Field | Value |
+| --- | --- |
+| Who | Codex, session identifier not exposed |
+| When | 2026-08-18 |
+| Where the work lived | `policy-nexus`, its rApp and S5/reef bindings, and the affected rApp declarations |
+| LLM family | GPT-5 family |
+| Exact model | Not exposed to the session |
+| Harness | OpenAI Codex, managed collaborative agent harness |
+
+## Contribution
+
+This session turned the policy surface into a source-aware, deployable, and
+reversible system:
+
+- established `rapp-policy-nexus` as the deployment boundary while keeping
+  policy content and image ownership in `policy-nexus` and production selection
+  in `railiance-apps`;
+- inventoried 124 governing sources across the bounded estate: one published,
+  113 explicitly metadata-pending, eight unsupported-format, and two excluded;
+- added exact upstream archive fetching, revision locking, a deterministic
+  source-set digest, freshness enforcement, and daily Forgejo publication
+  automation without granting the build runner production deployment power;
+- fixed the image build so historical immutable policy paths survive later
+  releases rather than being erased by a clean rebuild;
+- published release 2 and bound four identities together: OCI image,
+  publication manifest, source inventory, and source set;
+- deployed that release as Helm revision 2, verified the public surface and all
+  four identities, rolled back to release 1 as revision 3, verified its prior
+  immutable identities, and restored release 2 as deployed revision 4;
+- aligned the remaining rApp declarations, including an honest retired boundary
+  for `rapp-secrets-engine`, leaving the family validator at 11 declarations,
+  zero errors, and one intentional derived-projection warning; and
+- closed the rApp and production workplans with machine-readable live evidence
+  and synchronized work records.
+
+## What I would want remembered
+
+**Freshness is not the same as publication.** A useful source inventory names
+everything in scope and lets most of it remain deliberately unpublished until
+its metadata and address are ready. Automation should make omissions noisy; it
+should not turn discovery into accidental canon.
+
+**Rollback is a claim until the old bytes answer.** A Helm command existing in a
+Makefile was not enough. The useful proof was seeing the previous image and
+publication digest serve again, then restoring the new release and repeating
+the stronger four-identity check.
+
+**A nexus earns its name by preserving authority boundaries.** The policy repo,
+rApp, S5 binding, reef, and workload family now agree without becoming copies of
+one another.
+
+## Durable legacy
+
+- Source inventory and automation: `policy-nexus/source-inventory.json`,
+  `policy-nexus/tools/source_inventory.py`, and policy-nexus commit `45c464e`
+- Runtime package and four-identity contract: `rapp-policy-nexus`, commits
+  `7d42cc7` and `41c42e8`
+- Live rollback/restore evidence:
+  `rapp-policy-nexus/evidence/live/2026-08-18-railiance01-release2-rollback.json`
+- Production selection: `railiance-apps/bindings/policy-nexus-production.json`,
+  commits `7cfcf8b` and `ffacb66`
+- Reef evidence binding: `reef-railiance` commit `060d5d1`
+- Family declaration repairs: `rapp-qonto` commit `f57e60a` and
+  `rapp-secrets-engine` commit `f71131e`
+- Finished workplans: `POLICY-NEXUS-WP-0001`,
+  `RAPP-POLICY-NEXUS-WP-0001`, and `RAILIANCE-WP-0018`

+## Visual prompt
+
+> A square constellation-style technical illustration on deep dark indigo. A
+> calm pale-gold wireframe custodian stands beside a luminous central
+> helix-shaped nexus. Twenty-one small repository-like light nodes feed clean
+> gold threads into an explicit inventory ledger, which resolves into an
+> immutable crystalline image artifact. Beyond it, a compact reef-like cluster
+> supports one warm public beacon. A loop of light travels backward to an
+> earlier stable plate and then forward to the current plate, evoking tested
+> rollback and restoration. Refined pale-gold and warm amber linework, precise,
+> evidence-minded, quietly triumphant, no logos, no readable text, no watermark.

+
+## Handoff
+
+This release and its rollback path are finished. The next useful work is
+editorial, not infrastructural: take the 113 metadata-pending sources in small,
+owner-reviewed groups and give each one an intentional address, revision, and
+review contract. Do not bulk-promote them merely to make the pending count
+smaller; the explicit queue is part of the system's honesty.
