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.

*/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).

*/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.

Manual smoke

# 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}' \

# idle suspend (use a huge minutes value to dry-run safely)
curl -X POST -H "Authorization: Bearer $NEXTAUTH_SECRET" \

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.

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.
