Keep the proven frame cost and GPU reference for each cap, and probe the shorter hold when a movie or thermal cap ends. Otherwise a GPU-bound game can fall straight back to 30 fps without a usable recovery reference. Save an uninterrupted sustained run when a cap begins, even if no earlier hitch populated cref. Keep the earlier reference through short runs and update it after another sustained run. Count cap-release probes and give them all 30 grace frames: the completed frame at the old cap consumes none. Add movie and thermal recovery regressions, including first movies, repeated caps, full grace and failed-probe backoff. Document the mechanism and link it from both Zelda game notes. Validated: 64/64 frame-step checks, including ASan/UBSan; six checks fail against the original PR. Production thermal tests and ThreadSanitizer, docs tests and diff checks pass; the BotW Mac host builds. Device clock recovery remains modelled, without a new gameplay observation.

Subsystem references
How the host meets each part of a Switch game, and every failure met so far, one entry per mechanism: symptom, cause, fix (file and function), the games it was found on (linked to their notes in dm/games/<id>/README.md). Start from the symptom index when you have a log line or a visible result; the workflows that lead here are in docs/agents.

A new general finding goes into the file and section it belongs to, in the same form, with a line in the symptom index; a fact about one game goes into that game's note.
