Import the deliverable's own test-case script.

Import the deliverable's own test-case script: markdown is the submission checklist — its §6 cases, and its starter prompts and release notes when it carries them — parsed deterministically, so malformed markdown is a named 400 and nothing is stored. starterPrompts, releaseNotes and platforms override what it says. The script is this deliverable's alone; the import bumps scriptVersion and clears every variant's last check.
