Rapid GSAP edits (ease/duration/keyframe/property) fired overlapping read-modify-write POSTs to one script file — coalesceKey only dedupes edit history, not requests. The gsap_fidelity shadow then diffed an op against whichever POST's scriptText resolved, which could predate that op → false "expected null, actual power2.out" mismatches. Server persists correctly; a pure client request-pairing race. Adds createKeyedSerializer (per-key promise chain, rejection-safe, self- cleaning). commitMutation now serializes every GSAP-script commit per target file by default (key `gsap-file:<path>`) — covering all op types and all animations, not just one meta family — so same-file POSTs can't interleave. Distinct files run concurrently; an explicit serializeKey still overrides. Co-authored-by: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
