1\section{Visual evidence gallery}2\label{app:gallery}3Every image below is an unmodified or cropped capture of a real surface, recorded in the screenshot manifest (\texttt{evidence/manifests/screenshots.csv}) with its capture mode, tool, UTC time, SHA-256 of the original and of the public copy, and the run and event it documents. Capture failures are listed with their reason and have no image. Hashes attest file integrity relative to the manifest; they do not independently prove the moment of capture, which is triangulated with the session and event timestamps in the state store.4\paragraph{S001 (no image)} \textbf{S001} --- mode \texttt{viewer\_postrun}; 2026-10-30T03:42:35 UTC; run RD0002; tool /usr/sbin/screencapture (macOS 27.0); original SHA-256 532a5184efbfe3de\ldots; public SHA-256 --\ldots; none. CAPTURE FAILURE: window-level capture of Safari produced the browser chrome without the page content (web content is rendered out of process); retained as a record of the failure, not usable as evidence.
