…8483) The Zero backup-monitor polls Litestream's `/metrics` endpoint to determine the safe replication watermark for changelog pruning. Without a configured `addr`, Litestream never serves its metrics endpoint, so the backup-monitor can't reach it (`ECONNREFUSED` on `localhost:4850`). This means the changelog table never gets pruned — it grew to 6.7GB (75% of the DB) in 6 days. This adds `addr: localhost:4850` to the Litestream config so it serves metrics on the port Zero expects (default port 4848 + 2). ### Change type - [x] `bugfix` ### Test plan 1. Deploy to staging 2. Verify `curl localhost:4850/metrics` returns litestream metrics from inside the RM container 3. Monitor changelog table size — should start decreasing as backup-monitor triggers cleanup ### Release notes - Fix Zero changelog table growing unbounded by enabling Litestream metrics endpoint for backup-monitor. ### Code changes | Section | LOC change | | ------- | ---------- | | Apps | +1 / -0 |
Disables Zero deployment on production branch while we resolve WAL accumulation and replication slot invalidation issues. The Zero replication slot was consuming 4GB WAL (hitting `max_slot_wal_keep_size` limit) and getting invalidated, causing cascading issues including Supabase restarts and sync-worker slot invalidation. Staging (`main` branch) continues to deploy Zero normally. ### Change type - [x] `bugfix` ### Test plan 1. Merge to `main` — staging deploy should still deploy Zero (`flyio-multinode`) 2. Merge to `production` — should skip Zero deployment entirely ### Code changes | Section | LOC change | | -------------- | ---------- | | Config/tooling | +1 / -1 |
