+### Scribe long-term history (verified 2026-08-29)
+
+- **Scribe 3.8.0** (`/homeassistant/custom_components/scribe/`), configured from
+  `configuration.yaml` (`scribe:` block; config entry
+  `01KC2VFJWEQ3XDHY6TQKHPDVRB`, `source: import` — UI "Configure → Advanced"
+  edits are overridden by the YAML on restart; treat YAML as authoritative).
+- TimescaleDB at `192.168.55.15:5432/scribe` (DB user `hass`; host in inventory,
+  see [hosts/pgdb.md](../hosts/pgdb.md)). Database re-initialized 2026-08-29 14:06 CST
+  (user-handled; earlier `relation "entities" does not exist` errors resolved).
+  Health: `binary_sensor.scribe_database_connection`.
+- 2026-08-29 config applied (backup `/homeassistant/configuration.yaml.bak-20260829-scribe`):
+  - `record_events: true` with `include_events` whitelist: `automation_triggered`,
+    `matrix_e2ee_command`, `matrix_e2ee_message_received`,
+    `matrix_e2ee_verification_done`, `script_started`, `tag_scanned`,
+    `mobile_app_notification_action`, `homeassistant_start`, `homeassistant_stop`.
+  - State noise trimmed: `exclude_domains` update/button; glob
+    `sensor.zigbee2mqtt_bridge_*`; 4 hassio cpu/mem-percent entities.
+  - Global `exclude_attributes` drops tianqi `hourly_*` arrays (~19 KB/state —
+    the recorder-side `_unrecorded_attributes` patch does not apply to Scribe).
+  - `enable_stats_io` + `enable_stats_size` on → 14 `sensor.scribe_*` stats
+    entities (`scribe_states_written`, `scribe_events_written`, rates, sizes).
+  - Verified post-restart 14:23 CST: writer started, `scribe_events_written=1`
+    (homeassistant_start), states ~110/min, buffer 3, no scribe log errors.
+- **Scribe 3.8.0 has no retention option** (upstream feature, newer versions
+  only). Retention requires upgrading Scribe first; the DB is a fresh 3.x-schema
+  so an upgrade is safe. Do not expect retention YAML keys to validate on 3.8.0.
+- Recorder stays external-Postgres with `purge_keep_days: 30` for daily UI
+  history; Scribe is the permanent archive.
