The first version kept the PostgreSQL-era pool configuration: up to 100 connections, with the tests running across eight workers.</p> <p>The suite began failing with <code>500 Internal Server Error</code> responses and <code>Database busy</code> messages. The failures looked intermittent, but the underlying mismatch was straightforward: we had changed the database without changing our model of write concurrency.</p>
