## What runs where (after cutover)

```text
activity-core schedules (Europe/Berlin)
        │
        ├─ (ideal) IssueSink → claimable work → agent-harness poller
        │     currently: ISSUE_SINK_TYPE=state-hub → progress only (no claim)
        │
        └─ interim: railiance01 systemd user timers
              scripts/railiance-rhythm/run-{daily,mail,review}.sh
              → agent-harness run | mail-scan
              → hub progress + local commits (deploy key)
```

Install / reinstall timers on railiance01:

```bash
cd ~/binky-control && git pull
./scripts/railiance-rhythm/install-on-railiance.sh
```

## Residual after BINKY-WP-0006 (2026-07-22)

| Gap | Status / follow-up |
| --- | --- |
| Post-scan **triage** via llm-connect | **Done** — `agent-harness mail-triage`; three clean railiance cycles 2026-07-22 |
| Daily brief without host coding agent | **Done** — `brief-daily` |
| Weekly review prep without host coding agent | **Residual intake AWQ-011** — `brief-weekly` (same pattern) |
| Host timers dual activity-core schedules | Simplify when in-cluster CronJob/poller owns cadence |
| **Out of scope / rejected:** install Claude Code on railiance01 | — |

## Rollback

1. `ssh railiance01 'systemctl --user disable --now binky-rhythm-*.timer'`  
2. Re-add workstation cron line (see OperatingRhythm.md rollback).  
3. Optionally set activity-core definitions `enabled: false` if schedules must pause.
