Oskar Kapala	20f6761a67	feat(ha-diag-agent): UnavailableEntitiesCheck with root cause dedup ... - shared aiohttp ClientSession in HAClient (Phase 1 Flag #2 fixed): make_session() factory, session injected at startup, closed on shutdown - Check.run() → list[CheckResult]: clean multi-event interface - first real diagnostic check: entity unavailable > 24h (INSERT OR IGNORE baseline preserves first-seen timestamp) - root cause grouping: emit ha_integration_failed instead of N entity events when ≥50% of integration's entities are unavailable (≥3 min) - alert deduplication via SQLite cooldown window (default 6h) - recovery clears baseline + dedup for immediate re-alert - configurable thresholds: duration, integration %, cooldown - 38 unit tests + 7 integration tests (42 pass, 3 skip w/o live HA) Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-05-29 13:41:55 +02:00
