+-- Player presence — the room instance a player is currently in, plus the status
+-- fields the match heartbeat echoes back. Stored as a JSON blob in `data` with
+-- generated (virtual) columns for the fields we query on, the same pattern as the
+-- rooms/room_instance tables. One row per account (unique `account_id`); writes
+-- upsert via INSERT OR REPLACE. Rows carry an absolute `expires_at` (epoch
+-- seconds) — reads filter expired rows out and a cleanup pass purges them.
+-- Generated from packages/domain/src/presence-db.ts (PRESENCE_SCHEMA_DDL) — keep
+-- in sync. Written by the match/auth workers, read by match/rooms.
