What problem does it solve? After a /signoff review rejects a built slice with BLOCKER or MAJOR findings, someone fixes them — but "done" from the fixer is only a claim. This Skill closes that trust gap by re-inspecting exactly the named findings with an independent reviewer and flipping the slice's status card only on verified evidence. ## Core Features & Use Cases - Closed-checklist verification: Re-checks only the still-open BLOCKER/MAJOR items from the record — the list never grows mid-run, so re-inspection terminates instead of treadmilling. - Independent reviewer via /readers: The session that wrote the fixes never grades them; a fresh Opus-floor reviewer call verifies each failure scenario against the current source, executed where runnable and static where not. - Append-only ledger and card flip: Adjudicates fixed / not fixed per item, records fix-introduced defects as new entries, appends a dated punch-list block to the build doc and the slice's verdict doc, and updates the Status line per the BLOCKER/MAJOR mapping. - Use Case: After fixing three MAJOR findings from a failed signoff on Slice B, run "recheck slice B" to have an independent reviewer confirm each fix, log the results, and flip the card to signed off only if everything clears. ## Quick Start Ask the assistant to recheck the fixes for the slice that failed signoff, for example by saying "recheck slice B" after the signoff findings have been addressed.
