Reworks #568 to the shape asked for in review.
Generalized from "AQHI" to a provider-backed Air quality layer, with ECCC's
AQHI as the first registered provider. Readings are carried as
{ provider, scale, value, band } rather than a bare number, because
air-quality indices are not interchangeable: AQHI runs 1-10+ on health risk,
the US AQI runs 0-500 on concentration breakpoints, and Europe's EAQI is a
five-step category. Naming the index a value belongs to is what lets another
network be added without inventing a shared numeric meaning. Coverage is
stated as "Canada only" on the provider, the layer row and the card.
Adds the WEATHER panel readout (readout: true) carrying the band legend and
the worst readings currently in view, with getRowControls/setRowControlsListener
following the wind and cyclone cards. An unresolvable view rectangle degrades
to the worst readings overall rather than to a blank card, and a rectangle
crossing the antimeridian is handled.
update() now takes the earthquakes layer's abort-and-guard shape: it aborts any
in-flight request, passes the signal through to the source, and refuses to
touch the scene when the request was superseded, aborted, or the layer was
disabled while it was outstanding. disable() and destroy() abort too. Tests
cover the late-response, superseded-refresh and disabled-update paths.
Rebased on main: the source is registered in src/sources/reference.js, and the
allocation profile was re-measured against the current worker — median 3,900
B/frame, max 4,114, 85.7 B/candidate, inside the shared 154 ceiling, budgeted
at 5,200 for 26% headroom. The earlier figures no longer held.
Freshness is now judged on the observation time rather than on when the last
response arrived. lastUpdate only says the feed answered; a station that keeps
returning a reading from four hours ago would otherwise be narrated as live by
the HUD and the voice provenance envelope. getStats() reports observedAt and
stale, so layerFeedState() calls the layer stale past two missed hourly
publications, and degraded when a refresh fails over readings that are still
good.
The share-link token is 0, which is what layer-token:next allocates. Taking it
moves the ledger fixtures that had hard-coded 0 as the free digit and 3 as the
one after; those shift to 3 and 4. The pinned equality between the reservation
ledger and LEGACY_LAYER_STATE_TOKENS also had to become "the closed legacy set
plus air-quality", since that set is documented as never growing. Happy to
re-pin this differently if you would rather the fixtures derive the provisional
digits from nextLayerStateToken() so the next layer does not move them again.
The layer and its source are registered as ./layers/air-quality and
./layers/air-quality/source, each with its own boundary group, following the
perimeters pair. check:boundaries requires the package exports and the group
exports to be the same set, so a layer that ships a source needs both.
Adds MODIS NRT to Active Fires and a keyless Fire Perimeters layer (NIFC WFIGS) with
InciWeb incident links, served through a capped, cached /api/fire-perimeters proxy.

Adds a Local ADS-B layer fed by your own receivers: a browser WebUSB
RTL-SDR (with FM listening) and local 1090/978 MHz decoder feeds
(LOCAL_RECEIVER_FEEDS, local and private addresses only). Local aircraft
draw in magenta with class, silhouettes, 3D models, trails and a position
sanity filter; the click card names the band and input that heard them.
Builds on Sameh Khamis's SDR prototype and the initial GEV port by
Mazeyar Moeini Feizabadi (#134); the decoder-feed design follows the
notes on #57. Closes#57.

Select a box on the world and browse the last 30 days of open satellite imagery over it, keyless: NASA GIBS Harmonized Landsat Sentinel-2 (30 m) and the VIIRS daily overview (250 m), with a day strip, IMAGE / VS BASEMAP / A / B modes with a swipe divider, PNG export and share links. The before/after swipe from the Nepal scene moves into shared modules so both use it.

Wind (NOAA GFS and ECMWF IFS: animated particles, colour field, a reading at map centre), observed weather (NOAA MRMS radar, GOES and NESDIS infrared clouds, lightning density) on one shared history timeline, NHC and CPHC cyclone advisories with tracks and cones, and a WEATHER panel in the right rail. On 3D Tiles the observed products render as raised shells with a sharper window around the view.

Supersedes #218 by @spcpza, ported onto the current component layout with fixes from review.
Verified before merge: format, package boundaries, unit suite, build, and the browser tracking suite; a browser harness for the change where one applies; adversarial review applied.
Contributor: @spcpza. His original commit is the base of this branch, and his own re-port onto main (2026-09-15, `5b69011`) was consulted while finishing the height work. That port reads every vehicle's surface from the app's shared ground-floor system (`cachedGroundFloor` / `warmGroundFloor` / `GROUND_FLOOR_LIFT_M`) rather than sampling the scene per layer, keeps a vehicle hidden until its cell answers, warms a bounded batch per poll on a timer instead of per frame, and renders at the ellipsoid above the altitude gate. That is the sounder primitive — one floor system for the app, with the rooftop-versus-street question already settled against a datum-correct DEM prior — and this branch's height work was rebuilt on it, replacing a bespoke cell cache, ground prior and rooftop rule written here. Credit for that direction is his.
Future work (not in this PR), both written up in docs/CURRENT-STATE.md:
- Readable route names. The realtime feeds carry only `route_id`; `route_short_name` / `route_long_name` live in each operator's static GTFS `routes.txt`, and headsigns in `trips.txt`. Doing it properly wants a server-side metadata loader beside the transit proxy with fixed registered static sources, bounded indexes built once and persisted, a slow conditional refresh, and a versioned route dictionary the browser caches. Shipped here: ids are never rewritten, and a cut one carries an ellipsis instead of reading as a typo.
- Below-ground rendering. Subway vehicles are drawn on the surface directly above themselves, because the feeds carry no depth and a train nobody can see is not worth drawing; the card says so plainly. Real treatment wants OSM tunnel geometry per city and a ghosted sprite tethered to the surface. The owner recorded it and left it.
Round four and after (2026-09-15). The owner tested round three under FLIR and NVG, and then asked for the design to be taken further: elegant in performance, beautiful on camera, trails with a cache for public transport, Cesium-native, and a core other moving layers can adopt. Codex Astra reviewed the plan (it confirmed the speed fault: a glide started from the drawn position at receipt time but spanned the gap between report times, so with MBTA reporting every ~10 s against a 15 s poll every second glide ran at 1.5x; it rejected a queued-segment patch), then wrote the design, then implemented it in commit-sized passes with adversarial review between them and real-browser harness runs by the integrator.
What this PR now contains beyond the contributor's original port:
- Delayed playback in a contact-agnostic core (`src/data/contactPlayback.js`): each vehicle keeps a typed, bounded fix history and a display clock that runs at one second per second through it, a feed-derived lag behind real time, holding at its newest fix rather than extrapolating and never sprinting to catch up. Marker, course, motion word, card and trail all read the same displayed sample. The clock has an explicit time-offset and seek API so a rewind is a later feature, not a rewrite; flights and vessels are untouched.
- A selected-vehicle trail (`src/data/contactTrailRenderer.js`, `src/layers/transit/trails.js`): the retained history drawn with batched Cesium primitives, clipped at display time so the head is exactly the sprite, faded by age, in the mode colour (white under sensor presets), on the same surface path as the marker.
- Bounded proxy-side history (`server/providers/transitHistory.js`): fifteen minutes and at most 128 fixes per vehicle with hard byte ceilings, MBTA only for now (opt-in per feed), served by a small endpoint that never fetches upstream, so a selected trail survives a browser reload while the server keeps running.
- Scene work bounded to what is visible and moving, an occluder, cached DETECT candidates, holds on the render loop only while something visible moves.
- Sensor presets: white-hot haloed sprites under NVG/FLIR/noir (black-hot inverts), saturated mode colours under CRT, per-mode bracket tiers in every theme, the selected card keeping its mode colour.
- A discriminating browser harness (`scripts/qa-transit.mjs`) that samples postRender frames, reads the real card anchor, and measures fleet budgets at 800 and 3,000 vehicles.
Not built, recorded as follow-ups: curated route display names (lowest priority per the owner), fleet-wide tails, route snapping, a rewind UI, adoption of the playback core by flights and vessels.
Verified at merge (2026-09-15 morning): unit suite 3,896 passing, build clean, format and boundary gates clean, tracking regression 109/109, browser harness keyless 200 pass / 0 fail (13 sensor checks unexercised because the live view offered fewer than six isolated sprites; every judged sprite passed), keyed on Google 3D tiles 198 pass with the per-frame allocation gate as the only failure. Follow-ups recorded: the keyed build's playback sampler still allocates per frame (CPU and frame time stay within budget; the 3,000-vehicle metro view sits at a 27.6 ms frame interval against a 25 ms budget), the shared detection overlay's per-paint allocation, friendlier route names, fleet-wide tails, a rewind UI, and adopting the playback core for vessels and flights.
