Why: The approved revision spans Backend, UI and Documents and needs one reviewable Dev composition. Evidence: Backend go test ./...; UI 158 tests and typecheck; Frontend 84 affected tests; exact component SHAs recorded in the task card. Impact: The task card keeps real-model QA NOT_RUN and the earlier failed sample separate from this candidate. Refs: U3 quality revision r0.2
