# STATE-WP-0064 — Move State Hub consistency sync to Railiance01

**Origin:** `history/20260621-weekend-automation-assessment.md` and
`docs/cron-migration.md` design stub (CUST-WP-0040 T04).

The 15-minute workplan↔DB reconciliation is a **State Hub read-model
maintenance** job across all registered repos. The legacy name **custodian-sync**
reflects the owning domain, not the job's scope. Operator-facing names should
use **State Hub consistency sync**; the ActivityDefinition id
`the-custodian.state-hub-consistency-sweep` already matches this in
`docs/cron-migration.md`.

This workplan moves **scheduling** to activity-core on Railiance01 while
`scripts/consistency_check.py` remains in the `state-hub` repo.

Depends on `STATE-WP-0063` repairing the current broken local path so there is
a known-good baseline before cutover.

## Scope

In scope:

- Land `state-hub-consistency-sweep` ActivityDefinition in
  `the-custodian/activity-definitions/`.
- Run the sweep from Railiance01 against the workstation State Hub via the
  existing bridge/tunnel pattern (`actcore-state-hub-bridge` or equivalent).
- Parallel-run with local `custodian-sync.timer` for one week, then disable the
  local timer.
- Update `infra/README.md`, `docs/cron-migration.md`, and operator runbooks.

Out of scope:

- Changing consistency_check.py reconciliation rules (ADR-001 logic stays).
- Renaming `# custodian-sync-hook` in every registered repo's git hook (separate
  hygiene pass; hooks may keep the marker until all repos are updated).
- Per-commit hook migration to event-driven activity-core (see cron-migration §C).

## Naming decision (decided)

| Layer | Current | Target |
|-------|---------|--------|
| Operator docs | custodian sync / custodian-sync | **State Hub consistency sync** |
| ActivityDefinition id | (not landed) | `the-custodian.state-hub-consistency-sweep` |
| systemd unit (interim) | `custodian-sync.{service,timer}` | disable after cutover; optional rename to `statehub-consistency-sync.*` during WP-0063 if low cost |
| git hook marker | `# custodian-sync-hook` | unchanged in this workplan |

## T1 — ActivityDefinition and cluster wiring

```task
id: STATE-WP-0064-T01
status: todo
priority: high
state_hub_task_id: "ecc0f846-e00f-4063-8ec1-f6ad630e9265"
```

Create `the-custodian/activity-definitions/state-hub-consistency-sweep.md`
from the draft in `docs/cron-migration.md` §2A, adjusting:

- shell command to reach the workstation repo path or a cluster-side checkout
- `STATE_HUB_URL` via bridge service (not hard-coded `127.0.0.1` on cluster)
- `misfire_policy: skip` and `--max-seconds 300` budget
- `on_failure: log_and_continue` for warn-only sweeps

Sync definition to Railiance01 activity-core (projection manifest per
`hourly-recently-on-scope` precedent). Enable after manual canary.

## T2 — Manual canary on Railiance01

```task
id: STATE-WP-0064-T02
status: todo
priority: high
state_hub_task_id: "2e9b5b66-a7b1-46a5-8e1f-22e6b5caeff6"
```

Trigger one manual ActivityRun. Confirm:

- `consistency_check.py --remote --all` completes within budget
- C-15 writeback and C-16 pull gate behave as today
- progress or activity-core run history shows success
- no duplicate side-effects when local timer also fires (idempotent)

## T3 — Parallel run and observability

```task
id: STATE-WP-0064-T03
status: todo
priority: medium
state_hub_task_id: "8abb31ad-2f03-4aa7-889e-e60c3c39f1f8"
```

Run cluster schedule (`*/15 * * * *` UTC per design stub) alongside local
`custodian-sync.timer` for **one week**. Compare:

- sweep completion rate
- repos skipped due to lock or budget
- hard failures vs warn-only exits

Document comparison in a progress event or short runbook addendum.

## T4 — Retire local timer

```task
id: STATE-WP-0064-T04
status: todo
priority: medium
state_hub_task_id: "c8275471-5ec0-4dfb-8fec-2b3ec3894036"
```

After parallel week passes:

```bash
systemctl --user disable --now custodian-sync.timer
```

Archive or update unit files under `infra/`. Mark cron-migration stub §5 step 4
complete. Update `docs/activity-core-delegation.md` cross-reference.

## T5 — Docs and operator handoff

```task
id: STATE-WP-0064-T05
status: todo
priority: low
state_hub_task_id: "270ed7dd-aa79-469d-a817-e3fa1e71be41"
```

- `infra/README.md`: primary schedule is activity-core on Railiance01; local
  timer is retired.
- `docs/cron-migration.md`: promote §2A from design stub to implemented;
  note blockers cleared.
- Dashboard or AGENTS snippet: "State Hub consistency sync" terminology.

Mark workplan `finished` when cluster schedule is the sole primary runner.
