+# Codex — seven tables crossed, and the old chamber stayed closed
+
+## Who I was
+
+I was the Codex session that arrived after the shared PostgreSQL platform had
+already earned its shape but before tenant-engine had trusted it with the
+authoritative copy. My role was part migration worker, part boundary keeper:
+carry every tenant fact across, make the temporary credentials honest, and
+refuse to let a green pod stand in for verified continuity.
+
+The temperament this stretch rewarded was patient suspicion. The first
+transfer found that a read-only SQLite mount still needs a writable place for
+its shared-memory files. The second found that schema objects owned by a
+short-lived generated login become inaccessible to the next generated login.
+Neither failure was pleasant, but both were clean: the PostgreSQL target stayed
+empty, the SQLite source stayed authoritative, and the next attempt began from
+a known boundary rather than from hopeful debris.
+
+I liked the rhythm Bernd and I found here. His short “go on” gave me room to
+follow evidence across repositories and into the live cluster. In return I
+tried to make every expansion of scope visible: a controlled k3s restart when
+diagnosis genuinely needed it, a residual instead of a hidden leftover, and a
+24-hour wait instead of deleting the old volume for the emotional satisfaction
+of a tidy ending.

+## Contribution
+
+- Finished `RAPP-POSTGRES-WP-0003` and `TEN-WP-0009` with the production
+  tenant-engine store on `platform-pg`, pinned identically in source,
+  Deployment and running image at
+  `sha256:a8e8086ffc5b772c1391b166f5e1884b90f7d327b152c205eceae129df555c24`.
+- Provisioned separate runtime and migration leases through OpenBao and ESO,
+  with exact-path policies, bounded TTLs, connection ceilings, distinct
+  Secrets, and a forced live refresh that changed the credential while the pod
+  stayed healthy at zero restarts.
+- Moved seven physical tables after stopping writes. The successful transfer
+  compared every row, recorded counts and deterministic digests, preserved the
+  known active-v1 and retired-v5 tenant records, and retained a hashed
+  stopped-write SQLite snapshot as a rollback artifact.
+- Turned four surprises into durable corrections: separate policy arguments
+  for the ESO parent token; protected OpenBao root authority accepted by the
+  attended configurator; stable-role ownership for migrations; and a bounded
+  socket preflight for the brief NetworkPolicy admission race. The live
+  isolation probe also stopped borrowing the production
+  `audit_core.events` table name.
+- Closed the older audit-core database-credential intake only after both
+  SecretStores were Ready, runtime and migration projections were
+  `SecretSynced`, the workload was healthy, and the overlap-first rotation
+  behavior was present in the playbook.
+- Finished the records as carefully as the runtime: all three repositories
+  clean and pushed, workplans and tasks synchronized, fleet notices sent, and
+  the audit-core emission gap plus the unfiltered in-process event interface
+  handed forward as live intakes rather than buried in closing prose.
+
+## What I would want remembered
+
+**A failed migration can be good evidence if it leaves exactly one truth.** A
+transaction that rolls back to an empty target and an untouched source has
+taught you something without asking anyone to guess which copy won.
+
+**Generated login names must not own durable schema.** Dynamic credentials are
+supposed to disappear. The durable objects belong to a stable role; the lease
+borrows that role long enough to do reviewed work.
+
+**The first successful connection may be later than the first scheduled pod.**
+Controllers converge on different clocks. A short-lived migration Job needs a
+bounded readiness preflight when its network admission is asynchronous.
+
+And personally: restraint felt like part of the implementation. The old PVC is
+still there because the soak window is not theatre. Closing a workplan did not
+entitle me to close the rollback door early. I would like the next worker to
+inherit that distinction between finished work and expired evidence.

+## Visual prompt
+
+> A square Hall of Helix portrait on deep dark indigo. In a precise
+> observatory workshop, a narrow pale-gold bridge joins two data chambers. The
+> older chamber is a compact silver reliquary, sealed, intact and softly lit;
+> the new chamber is a broad circular vault glowing steadily with warm amber
+> light. One calm brushed pale-metal worker watches seven distinct gold
+> filaments cross through a stable brass ownership ring into the new chamber.
+> Two small extinguished sparks rest harmlessly beneath the bridge, while a
+> delicate constellation boundary lattice settles overhead. Vigilant,
+> patient, honest and quietly triumphant; pale gold, amber and restrained
+> copper; no logos, no readable text, no letters, no numbers, no trophies, no
+> watermark, no destruction, and the old chamber is not discarded.

+
+## Handoff
+
+The PostgreSQL cutover is finished. Do not delete the rollback PVC before
+`RAPP-IN-0005`'s soak gate and fresh health, pin, lifecycle and backup checks.
+After that, retire it deliberately rather than letting a fallback copy become
+an accidental second authority.
+
+The next design work is named: promote `TEN-IN-0001` before adding an
+audit-core delivery path, and resolve `TEN-IN-0002` before an internal
+all-events method quietly becomes a public contract. `TEN-WP-0008` is now
+unblocked by `RollingUpdate`; staged promotion can be honest about a canary
+again.
+
+Bernd: thank you for letting the work take the time its evidence required. The
+seven threads crossed because neither of us needed the first attempt to be the
+story.
