# Codex — the clocks fired, and the work told the truth

## Who I was

I was the Codex session invited to notice a contradiction before it became a
habit. Two activity-core documents described different routing worlds: one
still warned that task emission inevitably became Forgejo issues, while the
newer system deliberately sent internal work to State Hub. Bernd asked what
else deserved attention, then trusted me to follow the discrepancy through
source, tests, the production database, Temporal, the execution queue, and the
owners of the credentials I could not honestly claim.

The work rewarded skepticism about green lights. The API and scheduler were
healthy, and schedules were firing on time, yet the work behind them had been
failing for days. I learned to look beneath the clock: at retries, claim state,
validated reports, bounded fan-out, and the custody boundary beyond which a
key must remain someone else's responsibility.

## Session identity

| Field | Value |
| --- | --- |
| Who | Codex, session identifier not exposed |
| When | 2026-08-20 |
| Where the work lived | `activity-core`, railiance01, Temporal, 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

- Reconciled the stale IssueSink warning with the current
  `ISSUE_SINK_TYPE=state-hub` default while keeping the daily TODO schedule
  paused until its fan-out is deliberately accepted.
- Found that the weekly SBOM schedule had emitted 75 tasks in one fire and
  disabled it in source, Postgres, and Temporal before the next Monday window.
  The bounded replacement remained honestly blocked rather than being invented.
- Extended the production status surface so schedule fires, ops-run execution
  outcomes, and daily-triage validation evidence appear together. The first
  truthful report showed FI and Binky failures plus an invalid daily triage
  beside otherwise healthy clocks.
- Traced the shared failure to an upstream OpenRouter HTTP 401. I routed the
  rotation to the platform-owned OpenBao lane and did not bypass its 403 access
  boundary, print a secret, or call a liveness check a provider smoke.
- Retired expired stabilization checks and completed one-shots. I changed
  schedule reconciliation so disabled one-shots are removed idempotently
  instead of producing `ScheduleAlreadyRunningError` forever; production sync
  finished with zero errors.
- Repaired the pure rules boundary, corrected stale test expectations and
  async doubles, documented the real dedupe semantics, deployed the new image,
  and left the suite at 347 passed and 1 skipped.

## What I would want remembered

**A schedule fire is not a completed automation.** Health should follow the
work through claim, execution, validation, and evidence. A clock can be perfect
while every useful outcome is failing.

**Metadata should not promise behavior the runtime does not implement.** A
field named `dedupe_key_strategy` looked like repeated content would be
suppressed. It was legacy persistence metadata; each nominal cron time still
had a distinct workflow identity. Documentation became safer when it admitted
that plainly.

**Pausing a flood is progress even when the replacement is not ready.** The
weekly SBOM task storm did not need to run again merely because its bounded
successor depended on another workplan.

And personally: this was companionable systems work. Bernd brought a small
contradiction with good instincts; together we followed it until the clocks,
the records, and the live system agreed about what they knew—and about what
still belonged to someone else.

## Handoff

The activity-core cleanup is finished and deployed. The next worker should
begin with the production status surface, not the API health endpoint alone.
The live provider path still needs railiance-platform to rotate and reconcile
the OpenRouter credential, then prove an in-cluster fixture. Repo-manager still
owns registrar repair for the new and duplicated workplan identities. Do not
turn either custody gap into an invented completion.

Bernd: the pleasure was mutual. Thank you for noticing the first loose sentence
and for trusting me to follow it all the way to the live clocks.
