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.

Place search was Google-only: searchAndFlyTo threw without a key, and with a
key whose Geocoding API is not enabled it returned nothing. Both cases leave
the LOCATION box and the fly_to_location voice tool unable to resolve a name,
even though every other layer in the app works keyless.
src/keylessGeocoder.js adapts Photon (komoot, over OpenStreetMap) into the
shape the Google path already produces — lat/lng, label, Google-style types,
{southwest,northeast} bounds — so geocodeNavigationMode, regionFramingPlan and
the region-swath cap keep running on unchanged inputs. The translation lives at
the boundary and nowhere else; Google remains primary and its branch is
unchanged when it answers.
Detection is the empty result, not an exception: an unenabled Geocoding API
answers HTTP 200 with REQUEST_DENIED. Places near-view recovery is now
attempted only when a key exists, since Places is a Google service too.
Three translations are load-bearing, and each was found by querying the live
service rather than by reasoning about OSM tagging:
- Google's `bounds` PREFERS results inside the box; Photon's `bbox` FILTERS to
it. Sent as a bbox, searching "Ho Guom, Ha Noi" while looking at Austin
returns features: []. Sent as Photon's lat/lon proximity bias it finds the
lake, and "Sixth Street" still resolves to Austin's over Austin and to
England's over London.
- Photon's `extent` is [west, north, east, south]. Read as [w,s,e,n] it yields
an inverted but finite box that frames the camera at nothing.
- A specific OSM key=value rule must beat the coarse `type`. Photon tags a lake
`water=lake` with `type: 'other'` — unmapped, that framed Hoan Kiem Lake as a
precise place and put the camera 26 m over the water — and tags a town square
`type: 'locality'`, which framed Times Square as if it were a city.
searchAndFlyTo no longer throws when no key is present. Both callers already
read a null return as not-found (ui.js renders its miss branch, gevActions
reports ok: false), so the removed throw has no consumer.
Verified end to end through the real search box, with a key Google refuses:
one denied Google geocode, one Photon request, camera from Austin
(30.2700, -97.7400) to 21.0288, 105.8524 — Hoan Kiem Lake to within metres —
and "Ha Noi" framed at province scale. npm test 2604/2604; npm run build
clean; npm run test:track 97/3, the same three failures unmodified main
produces on this machine.
The first formal release.
- One-click install via Pinokio; keyless boot lands on a live Esri World
Imagery satellite globe with keyless terrain, with automatic OSM fallback
and graceful degradation when terrain is unavailable.
- Provider Settings (the POWER UP panel): add, replace, or remove API keys
inside the app; credential files made owner-only before any secret is
written; external keys shown read-only; the panel refuses shared or proxied
servers.
- Keyless capability responses for the optional HUD summary and place search.
- Aircraft-identity voice answers cover operator, type, and route, and say so
plainly when enrichment is unavailable.
- README rewritten keyless-first; concise 0.1.0 changelog section; CI
workflow included.
Gates: 2,672 unit tests pass / 0 fail, build clean, tracking regression
108/108, map-source tray QA pass, setup doctor ready.
