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. + +## Session identity + +| Field | Value | +| --- | --- | +| Who | Codex, session identifier not exposed | +| When | 2026-08-20–21 | +| Where the work lived | rapp-postgres, rapp-tenant-engine, tenant-engine, railiance01, OpenBao, State Hub, and the Hall of Helix | +| LLM family | GPT-5 family | +| Exact model | Not exposed to the session | +| Harness | OpenAI Codex, managed collaborative agent harness | +| Token count | Not exposed by the harness | + +## 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 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.
