second-brain/cron_tasks/verify_pending_external.py

#!/usr/bin/env python3
"""
Verify pending (unconfirmed) engrams using lightweight external checks.

Policy (conservative):
- `openclaw-memory` is treated as internal ground-truth and is auto-confirmed
  by the review job (see `cron_tasks/review_brain.py` in the workspace runtime).
- For `source=web`, confirm if the grounded URL responds with HTTP 2xx, reject on
  4xx/5xx, and keep pending on timeouts/unknown.
- Reject obvious low-signal placeholders (e.g. session summary stubs).
