+- `main`; relevant commits: vertical scaling through FFmpeg `6310f50`, Day 2 reconciliation
+  `f921c01`, Steam-frame-rate entitlement `7216c95`, Task 53 visual acceptance `1993e7c`.
 - 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.
-- Six creator-supplied output recordings match their named dimensions and frame rates; the creator
-  visually reviewed and accepted them. The vertical YouTube player check is also accepted.
+- TASK 53 is complete: six output recordings and the vertical YouTube player view were accepted by
+  the creator. Platform-specific safe zones are explicitly out of scope.
+- Output entitlement code now gates by frame rate; the paid Steam App ID still needs Steamworks metadata.
 - 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: verify the local vertical MP4 matches the YouTube live output.
+- Next queued coding task: TASK 3·17, the Text layer.
 - Do not push absent a checkpoint request.
