 - The top menu background follows YouTube's broadcast status: normal ON-AIR starts red and turns
   green only at `lifeCycleStatus=live`; TEST stays gold; stopping restores the idle surface color.
-  The focused test passes; the change is included in this work unit.
+- Six creator-supplied output recordings match their named dimensions and frame rates; the creator
+  visually reviewed and accepted them.
 - The focused top-bar test passes. The last full verification had a clean build and 522/523 tests;
   the only failure was the known `AudioPipelineTests.Mix_HonorsProviderGains_AndGameMute_KillsTheLoopback`.
 - Four untracked `Assets/llamacasty-*` files remain untouched.
 
 ## Next action
 
-- TASK 53 remains the next queued output task: inventory emitted tiers and pin their geometry.
+- TASK 53 remains the next queued output task: check 9:16 safe zones and caption placement.
 - Do not push absent a checkpoint request.
