chore: excise the dead Central NATS consumer path (-11,328 LOC) (#144)
* chore: excise the dead Central NATS consumer path
Central was retired and its database dropped 2026-07-15; its NATS broker no
longer exists. Verified against the live CT108 deployment: all 12 adapters
run feed_source=native, zero on central, and central.enabled is False
(default, never overridden). The consumer and its handlers were unreachable.
Removed:
- central/consumer.py and 6 dead handlers (nws, quake, swpc, nwis, avy,
incident) -- their handle_* entrypoints were reachable only from the
consumer's dispatch
- the Central wiring in main.py (init, guarded start, retry loop, stop path)
- the dead config surface: CentralConsumerConfig, EnvironmentalConfig.central,
adapter_config ("central","severity_thresholds") and its display block
- the nats-py dependency (consumer.py was its only importer)
- 19 test files that exercised only the dead path
KEPT -- these live under central/ but are imported directly by native
adapters, and deleting them would break production:
- wfigs_handler.py: firms_handler._handle_pass_boundary() calls its _render()
on the live FIRMS growth-fire path (env/firms.py -> ingest_hotspot_pixel)
- firms_handler, satpass_handler, tle_handler: split files whose handle_*
entrypoints are dead but whose engines are live. Left intact; splitting
them is separate work.
- pass_predictor, budget, idaho_gauge_sites: fully live.
The usgs_quake keys global_mag_floor / regional_mag_floor / regional_centroid
/ regional_radius_mi / broadcast_pager_alerts are NOT removed despite comments
labelling them "CENTRAL-PATH ONLY" -- notifications/gating/quake.py reads them
unconditionally in the native path. Those comments are corrected separately.
Test-count note: the suite drops ~425 tests. Most were migration PARITY tests
whose sole purpose was proving the native rewrite byte-matched the Central
handler (golden byte-parity, cross-source identity, gate-sequence replay).
With the handler deleted there is nothing left to compare against, so they
cannot exist. Native-only tests were kept and reworked where a test reached
for a central symbol incidentally. This is a real coverage loss, accepted
deliberately: the parity harness proved the refactor faithful, and git
history preserves the originals.
Suite: 1984 passed, 6 failed -- the same 6 pre-existing failures as main
(stale SCHEMA_VERSION x3, expired TLE fixtures x2, one order-dependent),
all being fixed on fix/green-test-suite. No new failures.

refactor(phase1): quake + swpc(Kp+flare) + avalanche, behind staged-cutover gate (#29)
* fix(fixtures): rewrite capture_fixtures.py to use ephemeral push subscribe
Previous script hardcoded stream="CENTRAL" which does not exist — Central
partitions into domain streams (CENTRAL_QUAKE, CENTRAL_SPACE, etc.). It
also called pull_subscribe_bind() without await, making the fetch a no-op.
Fix: mirror the proven CentralConsumer.start() pattern — use
js.subscribe(subject, cb=..., AckPolicy.NONE, no durable) which auto-
discovers the correct stream via the subject filter, identical to how the
live consumer binds. Messages are funnelled through asyncio.Queue with
an idle-timeout to detect drain completion.
Adds live captured fixtures:
- tests/fixtures/quake/ — 3 envelopes (CENTRAL_QUAKE stream, mode=all)
- tests/fixtures/swpc/ — 40 envelopes (CENTRAL_SPACE, mode=all, proton_flux history)
- tests/fixtures/swpc_last/ — 23 envelopes (mode=last: 21 alert variants + kindex + proton_flux)
Avalanche: confirmed empty off-season (CENTRAL_AVY stream, 0 messages).

* refactor(phase1): migrate quake, swpc(Kp+flare), avalanche + staged-cutover gate
First hazards on the source-agnostic formatter+decider path, behind a
staged-cutover gate so deploy = shadow-only (old path still broadcasts; new
path dry-run-diffed) until MESHAI_CUTOVER_CATEGORIES flips a category live.
- formatters/{quake,swpc,avalanche}.py + gating/{quake,swpc,avalanche}.py:
source-agnostic format(event,*,now,budget) + decide(data,*,source,now)->GateResult.
quake (earthquake_event, tier-b: render PAGER + live update-prefix), swpc
(geomagnetic_storm + rf_propagation_alert, Kp+flare only; proton/solar_radiation
_storm stays legacy; geomag 600s window re-homed off the module-global into
gating/swpc with a deferred stamp; tier-b scale-based severity), avalanche
(avalanche_warning/watch; centralseverity->NAADS 1-5 remap; synthetic fixtures
off-season).
- central/{quake,swpc,avy}_handler.py bridges: cutover -> new decide()+canonical
data; not-cutover -> exact legacy behavior. env/{usgs_quake,swpc,avalanche}.py
emit canonical Event.data (avalanche stops precomposing). env/store.py generic
native decider hook (cutover-gated).
- notifications/cutover.py (is_cutover via MESHAI_CUTOVER_CATEGORIES); composer
dispatch + shadow hooks are cutover-aware (shadow no-ops once a category is live).
- scripts/capture_fixtures.py fixed (per-domain streams e.g. CENTRAL_QUAKE, await
bind); real quake/swpc fixtures captured; avalanche synthetic.
Tests: +~150 (quake/swpc/avalanche parity+cross-source+gate-sequence+cutover);
0 new failures (34 baseline, 1426 passed).
