+**Status: prepared, not installed** — installing a self-running agent loop is
+a founder action (the Claude Code permission layer rightly refuses to let an
+agent install its own persistence). Everything else is ready:
+`scripts/rhythm-session.sh` runs a headless, lane-restricted Claude Code
+session that does queue hygiene, writes the daily brief, and pulls one
+autopilot item (agent name `agt-rhythm-bridge`; flock guard, logs to
+`~/.cache/binky-control/rhythm/cron.log`).
+
+**Enable (founder, one line):**
+```bash
+( crontab -l; echo '23 8 * * 1-5 /home/worsch/binky-control/scripts/rhythm-session.sh # binky rhythm bridge' ) | crontab -
+```
+
+**Disable:** `crontab -e` and delete the `binky rhythm bridge` line.
+
+This is explicitly a **bridge**: once activity-core definitions (T05) and an
+llm-connect executor (T06 follow-up) are live, the cron line is removed and
+scheduling moves to the sanctioned coordination layer.
+
+Guardrails baked into the script: Green/Blue lane only, allowed tools limited
+to file edits + git add/commit, no push, no network, one-run-at-a-time lock,
+bounded "maintenance pass" prompt.

+You are the Binky operating-rhythm bridge session (see OperatingRhythm.md).
+Work autonomously, Green/Blue lane only. Do, in order:
+1. Queue hygiene: check DecisionQueue.md (flag items older than 14 days),
+   OfficeHourQueue.md, RiskRegister.md escalation dates against today.
+2. Write today's daily brief to briefs/<YYYY-MM-DD>-daily-brief.md in the
+   format defined in OperatingRhythm.md (Decide now / Progress / Risks /
+   Best next hour; one screen max). Skip if today's brief already exists.
+3. If time remains, pull ONE item from AutopilotWorkQueue.md you can fully
+   complete in Green/Blue lane; mark it in_progress with agent
+   "agt-rhythm-bridge", do it, move it to the Completed log.
+4. Commit all changes with a concise message.
+Never touch Red/Yellow lane actions; queue them instead. Keep total effort
+bounded — this is a maintenance pass, not a project session.
