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

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

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

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

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

After parallel week passes:

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

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.
