The API runs on a GCP e2-micro because that's what Always Free covers - one instance, 30 GB of standard disk, an ephemeral IP. It turns out to be sitting exactly at that ceiling, which explains more of the outage two posts back than any single bug did.
The API went down behind a Cloudflare Tunnel error and stayed down through a reboot, an interrupted OS upgrade, a stale connection pool, and a box too small for its own workload. None of the four were the same bug.
The API's hosting decision is made: a free-tier GCP VM, Neon and Upstash, zero-downtime rolling updates on a single-node Swarm - and why the VM pulls its own updates instead of GitHub Actions pushing them.
A redirect was reported broken seconds after pushing. It simply was not live yet. How we check deploys now.
