Moves the last two live files out of the retired-Central folder. central/ is
now EMPTY and deleted entirely (incl. __init__.py).
- fire-fusion engine (ingest_hotspot_pixel + the growth/cluster/spotting
engine) → env/fire_fusion.py, next to its sole consumer env/firms.py.
- wildfire text renderer (_render + its live helpers) → env/fire_render.py.
THE COUPLING RESOLVED: firms_handler._handle_pass_boundary had a LAZY import
inside a function body — `from meshai.central.wfigs_handler import _render` —
sitting on the live FIRMS fire-growth path. It is now a normal top-of-file
import (`from meshai.env.fire_render import _render`), visible and greppable.
PURE MOVE — no behavior change:
- The parity oracle (test_fire_refactor.py) PASSES UNCHANGED (only its import
paths updated) — proving the fire wire output is byte-for-byte identical
before and after. Fire alerts say exactly what they said.
- handle_firms / handle_wfigs (dead entrypoints, only caller was the deleted
consumer.py) were KEPT and moved rather than dropped — the wording-cleanup
PR removes them deliberately. "When unsure, keep."
- fire_render.py's geo-helper imports still point at central_normalizer — that
file's split is a SEPARATE PR; carried the imports along, did not touch it.
Consumers + test import paths rewired. Full suite: 2059 passed, 0 failed.

Foundation for making all hazard formatting+gating source-agnostic. ZERO
behavior change — the formatter/decider registries are empty (get_formatter/
get_decider return None → existing precomposed/Mode-B path preserved), and the
shadow comparator is off unless MESHAI_SHADOW_CATEGORIES is set.
- notifications/formatters/ (registry+dispatch with family fallback), gating/
(GateResult + deferred-commit contract), both empty registries.
- notifications/clock.py determinism seam; route wfigs/quake/nws gating time
reads through it (identical values) so goldens can freeze time.
- formatters/_budget.py = copy of central/budget.py; central/budget.py is now a
re-export shim (import-smoke test guards it).
- compose_mesh_message consults the registry first (verbatim, no Mode-B re-cap),
falls back to legacy; _resolve_budget injects per-category budget.
- notifications/shadow.py + two DRY-RUN hooks (consumer._normalize, dispatcher
render): compute the new result and diff-log SHADOW_MISMATCH JSONL, but NEVER
commit/emit/write tables and always broadcast the OLD result. Inert by default.
- tests/harness (pinned_time/pinned_tz, byte-golden, gate-sequence) +
scripts/capture_fixtures.py (ephemeral read-only NATS capture); tzdata pinned.
Tests: +60 (18 scaffold + 42 harness/shadow); 0 new failures (34 baseline).
