"""Phase-2 NWS refactor tests — formatter+gater architecture verification.

Four test groups:

1. Golden byte-parity (tier-a): for each NWS fixture, run the OLD _render()
   under pinned_time+pinned_tz, then run the NEW format() from canonical
   data built by the Central bridge, and assert_byte_identical.  This MUST
   be exactly equal — any difference is a regression.

2. Cross-source identity: the native adapter's to_event() canonical dict
   (for a synthetic fixture) produces the same formatter output as the
   Central-bridge canonical dict built from the same alert data.

3. Gate-sequence: replay a synthetic 4-step lifecycle (first→dup<3h→
   dup>3h→Cancel) through the OLD handle_nws gating and the NEW
   gating.nws.decide(), and assert broadcast/suppress match at every step.

4. Schema-conformance: env/nws.py _fetch() emits all canonical schema keys;
   description is not truncated; to_event() produces a canonical event.data.
