Fix a branch's demo build
Fix a branch whose demo build is missing: apply the deterministic Ankra-side fixes first (publish-readiness auto-fix, failed-run rerun, failed-setup retry) and, when those cannot produce an image, dispatch a one-shot mission agent that investigates the repository and opens a pull request with the fix. Browser session authentication with the X-Ankra-CSRF double-submit header only (no bearer twin).
Authorizations
Bearer authentication header of the form Bearer <token>, where <token> is your auth token.
Path Parameters

Response
Successful Response
The fix-build answer: the deterministic actions taken, whether the build is already resolved or building, and the dispatched mission agent when one was needed.
