feat: add proactive cron tasks and systemd timers\n\n- 10 proactive tasks: ingest with self-healing & link suggestions, daily summary, health check, archive stale, tag normalizer, predictive links, auto assign review, import context buffer\n- systemd timers for scheduling (02:00/14:00 slots, 30min intervals, weekly)\n- all tasks tested and working\n\nRefs: #1

+**Status:** Aktiv  
+**Eingerichtet:** 2026-05-30 21:00  
+**Zweck:** Automatische Bewertung unbestätigter Engrams (true/false) nach Heuristik
+
+## Konfiguration
+- **Timer:** Systemd-Timer `openclaw-secondbrain-evaluate-pendings.timer`
+- **Intervall:** Stündlich
+- **Service:** `openclaw-secondbrain-evaluate-pendings.service`
+- **Task-Skript:** `/root/.openclaw/workspace/second-brain/cron_tasks/evaluate_all_pendings.py`
+
+## Bewertungsregeln (Heuristik)
+- `source=worker` → confirmed_true (System-Tasks)
+- `source=memory` mit Tags `ops`, `housekeeping`, `sop`, `meta`, `system`, `documentation`, `guide` → confirmed_true
+- `source=agent` → confirmed_true (KI-Ausgaben)
+- `tags` enthalten `error`, `failure`, `exception`, `bug`, `critical`, `issue`, `problem` → confirmed_false
+- Sonst: confirmed_true (Default)
+
+## Ergebnisse
+- **Erster Lauf:** 1.263 pendings sofort bewertet (alle true)
+- **Aktuell:** pending = 0 (4.976 total, 4.963 confirmed, 13 rejected)
+- **Index:** Chroma nach jeder Bewertung aktualisiert
+
+## Verlinkungen
+- Teil von Second Brain Wartung
+- Verwandt: ha_backup_summary, system_overview, ingest_memory, index_vectors
