 ## Phase 5 — MQTT Live Data Cutover
-**Status: NOT STARTED**
-**Prerequisite:** Phase 1 complete (device_logs in Postgres)
+**Status: COMPLETE** — Postgres live ingestion + partition manager active 2026-04-17
 
-This phase switches the **live MQTT ingestion** from SQLite to Postgres.
+### What changed
+- New `backend/database/pg_mqtt.py` — all MQTT functions rewritten for Postgres (raw SQL, no ORM)
+- `database/__init__.py` — re-exports from `pg_mqtt` instead of `core`
+- `main.py` — removed `db.init_db()` / `db.close_db()`, added `db.partition_manager_loop()`
+- `mqtt/router.py` WebSocket auth — reads from Postgres `staff` table instead of Firestore `admin_users`
+- `device_logs` partitioned writes, `heartbeats`/`commands` as plain tables
+- `purge_loop` still runs for heartbeats/commands; device_logs purged via partition drops
 
-### Steps
+### Steps (original plan, now implemented)
 1. Update `database/core.py` `insert_log`, `insert_heartbeat`, `insert_command` to write to Postgres
 2. Update read functions (`get_logs`, `get_heartbeats`, etc.) similarly
 3. The partition management background job: each month, at startup or via a cron, ensure next month's partition exists:
