Take 6 measured render 35-41ms — WORSE than take 5's 25.5 — and the run could not be attributed to a binary: exe mtime != build contents (incremental builds serve stale exes; a source edit without rebuild is a silent old binary). Three takes of a perf saga had been judged against builds nobody could prove. - ytLive.csproj GenerateBuildStamp target: fresh GUID per compile (writes obj/BuildStamp.g.cs -> Helpers/BuildStamp.Id/BuiltLocal). Deliberately defeats incremental lies: every 'dotnet build' recompiles the app project. - Wordmark shows the id as a superscript (TopBar.xaml, x:Static, 9px grey BaselineAlignment=Superscript); startup.log records 'Build <id> (compiled <time>)' so every take is cross-readable with the visible UI. - FramePump stats split the tick: 'avg render Xms (resolve Y), avg submit Z' — the resolver is timed separately (wrapper resolver on per-tick paths; bake keeps the raw one) so take 7 names the hot half of 'render' with data. - Fixed a latent transition-clock bug found on the way: lastTick now restarts every frame (the branch rework had restarted it only during transitions, letting a transition begun after idle complete instantly on its first Tick). ONE integration test family: BuildStampTests (unit: shape) + BuildStampDisplayTests (RealApp, namescoped FindName on TopBar proves the wordmark SHOWS the id). 47/47 per-class green, clean build 0 warnings. Docs same commit. User's top-bar/session spec (re-sent twice) + settled Q&A decisions folded into HANDOFF Unit B — next work unit after take 7 verdict.
