- memory_commit: closes the 'commit hole' — writes verified answers from
closed gaps back into atoms (mandatory dedup); leaves gap open if no
verified answer exists. Reads verified status from PostgreSQL (source of
truth), not the Qdrant projection.
- memory_stale: staleness guard with two signals — content-staleness
(re-fetch + LLM verdict, needs proxy for foreign sites) and age-staleness
(proxy-free fallback by pm_document.fetched_at, max_age_days).
- db: populate pm_document.fetched_at on upsert (freshness signal).
- docs: README/AGENTS/ARCHITECTURE/EXAMPLES updated (18 tools).
- self_improve.py: new module (227 lines).
