R3 review follow-ups on the keyframe cache: - clearKeyframeCacheForFile collected ids from the index.html alias prefix too, so a re-scan of one composition file wiped rows a sibling file had just written (several files re-scan concurrently). Only the file's own prefixed keys name the ids now; clearKeyframeCacheForElement still takes the alias and bare key with them. - toClipKeyframes fell back to a fixed 1s tween duration, which put a duration-less tween's keyframes at a percentage no edit path agreed with. It now spans the clip, matching resolveEditableTweenDuration. - collectAnimatableKeyframeProperties takes `object` so call sites drop their `as Record<string, unknown>` casts. Regression tests cover both fixes.
