The new page lacked incoming discovery and a complete docs shell. It used an undocumented exception name, ignored its caller request, and omitted tab-panel relationships. The empty fixture used success semantics. Unrelated tabs also triggered an inherited keyboard-handler error. The implementer's 19-check replay exited 0 but omitted material requirements, including the retry page. Every input, archive, reconstruction, changed-file and output seal remained intact. The verifier disclosed historic summary text in a tool response; its exact source could not be established, weakening clean-context isolation.
