# Path B cron entries

Two background jobs keep dev containers cheap and recoverable. Wire
both to whatever scheduler is convenient (host crontab, Coolify
Scheduled Tasks, or a separate vibn-cron service later).

## 1. Workspace autosave — every 5 min

Force-pushes `/workspace` of every running dev container to a
`vibn-autosave/main` branch in the project's Gitea repo. Throttled
internally so it's safe to call more often than 5 min if needed.

```cron
*/5 * * * * curl -fsS -X POST \
  -H "Authorization: Bearer $NEXTAUTH_SECRET" \
  -H "Content-Type: application/json" \
  -d '{"sweep":true}' \
  https://vibnai.com/api/admin/path-b/autosave \
  >> /var/log/vibn-autosave.log 2>&1
```

What it does on a per-project basis (see
`autosaveWorkspace` in `vibn-frontend/lib/dev-container.ts`):

1. Skips containers that aren't `state='running'`.
2. Skips containers without a `.git` directory in `/workspace`.
3. `git checkout -B vibn-autosave/main`, adds everything, commits if
   there are changes, force-pushes.
4. Records the push in `fs_dev_autosaves` (per-project history,
   bounded by retention you can prune later).

## 2. Idle-suspend sweep — every 5 min

Suspends every running dev container whose last `shell.exec` is older
than 30 minutes. Coolify-stops the service; the workspace + cache
volumes persist; resume happens automatically on the next
`shell.exec` (~3-5s).

```cron
*/5 * * * * curl -fsS -X POST \
  -H "Authorization: Bearer $NEXTAUTH_SECRET" \
  "https://vibnai.com/api/admin/path-b/idle-sweep?minutes=30" \
  >> /var/log/vibn-idle.log 2>&1
```

Override the threshold per-tier later by passing a different
`?minutes=` value. 30 was chosen because it covers a coffee break
without disrupting active work.

## Quick install on the Coolify host

```bash
sudo tee /etc/cron.d/vibn-path-b > /dev/null <<EOF
NEXTAUTH_SECRET=<paste-from-.env.local-on-coolify>

# Workspace autosave to Gitea
*/5 * * * * root curl -fsS -X POST \
  -H "Authorization: Bearer \$NEXTAUTH_SECRET" \
  -H "Content-Type: application/json" \
  -d '{"sweep":true}' \
  https://vibnai.com/api/admin/path-b/autosave \
  >> /var/log/vibn-autosave.log 2>&1

# Idle-suspend dev containers (30m threshold)
*/5 * * * * root curl -fsS -X POST \
  -H "Authorization: Bearer \$NEXTAUTH_SECRET" \
  "https://vibnai.com/api/admin/path-b/idle-sweep?minutes=30" \
  >> /var/log/vibn-idle.log 2>&1
EOF
sudo chmod 0644 /etc/cron.d/vibn-path-b
sudo systemctl reload cron
```

## Manual smoke

```bash
# autosave one project
curl -X POST -H "Authorization: Bearer $NEXTAUTH_SECRET" \
  -H "Content-Type: application/json" \
  -d '{"projectId":"<vibn-project-id>"}' \
  https://vibnai.com/api/admin/path-b/autosave

# sweep all
curl -X POST -H "Authorization: Bearer $NEXTAUTH_SECRET" \
  -H "Content-Type: application/json" \
  -d '{"sweep":true}' \
  https://vibnai.com/api/admin/path-b/autosave

# idle suspend (use a huge minutes value to dry-run safely)
curl -X POST -H "Authorization: Bearer $NEXTAUTH_SECRET" \
  "https://vibnai.com/api/admin/path-b/idle-sweep?minutes=99999"
```

## Disabling

If something goes wrong, flip the kill switch — the chat will fall
back to gitea-write tools and the cron sweeps will return `scanned: 0`
because no containers will be running.

```bash
curl -X POST -H "Authorization: Bearer $NEXTAUTH_SECRET" \
  https://vibnai.com/api/admin/path-b/disable
```

Re-enable later with `/api/admin/path-b/enable`.
