+### Issue 24: Missing Garmin Sync Cron Automation & Missing Activities Directory
+
+- **Date**: 2026-10-11
+- **Severity**: Medium (Automated nightly mirror of Garmin Connect metrics did not run; user suspected Garmin sync was broken)
+- **Symptom**:
+  Moritz noticed that Garmin Connect metrics (daily total expenditure, active calories, sleep scores, and activities) were not appearing in the newly deployed health dashboard (`moritz.html`) and nutrition log for recent days, suspecting the sync cron job was broken.
+- **Root Cause Isolated**:
+  1. **Unregistered Cron Job**: The setup script `k8s/openclaw/setup-garmin-cron.sh` had been authored during datastore implementation but was never registered in OpenClaw's cron scheduler (`openclaw cron list` showed 22 jobs, none for Garmin).
+  2. **Grep Truncation Failure**: In `setup-garmin-cron.sh`, the check `openclaw cron list | grep "$JOB_NAME"` was susceptible to CLI table truncation (e.g. `garmin-nightly-m...`), preventing reliable idempotent management.
+  3. **Missing Announce Flag**: The job lacked `--announce`, preventing fallback delivery to Telegram Topic 20 if authentication errors occurred.
+  4. **Missing Directory on PVC**: `garmin_sync.py` failed when saving activities because `/home/node/.openclaw/wiki/main/data/garmin/activities` was missing on the PVC.
+  5. **Outdated Dashboard Pipeline Step**: `setup-garmin-cron.sh` only called `render_views.py` and omitted `update_moritz_website.py` and staging `public/`, leaving the web dashboard unrefreshed after nightly runs.
+- **Resolution**:
+  1. **Hardened `setup-garmin-cron.sh`**:
+     - Switched idempotency lookup to `openclaw cron list --json` with `--declaration-key`.
+     - Added `--announce` for delivery of 2FA re-auth notices to Telegram Topic 20 (`fitness`).
+     - Added `update_moritz_website.py` and `git add public/` to the nightly automation pipeline.
+  2. **Created Activities Store**:
+     - Created `data/garmin/activities/` on the PVC and verified activity ingestion.
+  3. **Executed Setup Script**:
+     - Successfully registered `garmin-nightly-mirror` (`id: ea1f35b0-9b04-4433-bd1f-7266e60292e3`, cron: `30 3 * * * @ Europe/Berlin`).
+  4. **Backfilled Metrics**:
+     - Ran full sync for 2026-10-09, 2026-10-10, and 2026-10-11. All daily summaries, sleep logs, and activities were written to JSONL, views were re-rendered, and commits pushed to `knowledge-wiki`.
+- **How to Avoid Recurrence**:
+  - Always register cron jobs with `--declaration-key` and check existing jobs via JSON rather than table text grep.
+  - Document all declarative setup scripts in `AGENTS.md` under `Register / Sync Automations`.
+  - Ensure all data directories (`daily`, `sleep`, `activities`) are safely created in `GarminMirrorWriter`.
