Each keyframe-cache writer re-derived a clip-relative percentage inline, and the post-commit writer rounded to 0.1% while the others used 0.001%. Selection keys embed that number, so a commit-time rewrite could orphan a live key. toClipPercentage owns the rounding, toClipKeyframes owns the whole row (percentage plus the tween percentage and animation identity the lanes read), and the parsed write reuses elementCacheKeys instead of open-coding the three key variants.
