- dedupe files conflicts for disagreeing fields instead of dropping them - merged-away records never file removals - matched work committed before apply so retries reuse it (no draft leaks) - stale pending events superseded by newer values - multi-source engagement removal only detaches the source - list records applied with history-derived ownership - gone targets resolve as ignored; counts only for committed records Co-Authored-By: Claude Opus 5.5 <[email protected]>
