# 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.
|
||
|

||
## 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.
