Subject: [PATCH 001/113] refactor(providers): move the tile budget helpers out
 of the TomTom module

utcDayKey, normalizeBudget and isOverBudget move unchanged to
src/data/tileBudget.js. Nothing in them was TomTom-specific; the next
keyed tile proxy (Xweather) counts a monthly allowance through the same
two functions. tomtomTiles.js re-exports them, so the traffic provider
and its tests keep their imports.

Subject: [PATCH 002/113] fix(server): declare the method contract on the three
 read-only query proxies
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

/api/opensky, /api/adsblol/mil and /api/route answered any verb with the same
body while ignoring the request entirely. Measured against a running server
before the change: POST /api/opensky returned 200 with 833,759 bytes of live
state vectors, POST /api/adsblol/mil returned 47,372 bytes. Their siblings do
not: /api/geocode, /api/weather and /api/transit answer 405, and /api/overpass
is deliberately POST-only.

These three are read-only query proxies, so they now answer 405 to anything but
GET, using the wording and shape /api/geocode already uses. The refusal comes
first, before rate limiting and before any upstream call, which the tests
assert by stubbing fetch to throw.

Scope, stated plainly: this is a consistency and intent fix. No rate limiter
was being bypassed — /api/route already limits every request regardless of
verb, and the two aircraft routes have no limiter at all, only 9s and 12s
server-side caches that bound upstream cost for any method.

One existing fixture in src/search/geospatial.test.mjs built a request without
a method, which a real Node request always has; it now sets GET.

Verified on a running server after the change: GET still 200 on all three,
POST 405 on all three, /api/overpass and the other proxies unchanged.
Suite goes from 5090 to 5092 tests, 0 failures.

A malformed record answers 400 and a failed write 500, both with a fixed message.

 responses

RFC 9110 section 15.5.6 requires a 405 to name the methods it accepts, and
/api/radio/stations already does this in-tree. Thanks to kvnloo for catching it
on review. The same gap on the pre-existing handlers is tracked in #809 and is
deliberately left alone here.

Subject: [PATCH 005/113] feat(server): compress the cached OpenSky snapshot
 for clients that accept gzip

The ~860 KB snapshot is held for an adaptive 9-300 s TTL and was served as
identity bytes to every request; no response in server/ set Content-Encoding or
Vary. Gzip it once per refresh beside the cached body, off the event loop, and
return the body and the header that names it together so the two can never
disagree. Live against an anonymous snapshot: 874,002 B to 258,012 B, 3.39x,
decompressing byte-identical to the uncompressed response.

+- The live flight snapshot is compressed on the wire. `/api/opensky` gzips its

+  refresh and serves that frame to clients offering gzip — roughly 860 KB
+  becomes roughly 258 KB — while a client that offers nothing receives the same
+  bytes uncompressed. Both answers carry `Vary: Accept-Encoding`, and a response

Subject: [PATCH 007/113] fix(server): read the whole q value, not a numeric
 prefix
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Number.parseFloat accepts any valid numeric prefix, so `gzip;q=1oops` read as 1
and the out-of-range `gzip;q=2` was accepted — both contradicting the comment
two lines above, which promises that a quality this cannot read confidently
fails closed. Matching the qvalue grammar of RFC 9110 section 12.4.2 makes the
code do what it already claimed to do.

Thanks to kvnloo for catching it on review.

Subject: [PATCH 012/113] fix(voice): keep canonical analyst IDs out of
 display-text normalization

compactAnalystItem normalized every string field, including `id`.
Bikeshare uses the raw station name as its ID, so a station with
repeated spaces or a name over 180 code units was registered as a
referent under a different key and a numbered fly_to_location reported
it as no longer loaded. Normalize display fields only; layerKey, id,
icao24, mmsi, noradId, registration and callsign pass through as the
layer reports them.

Adds an analyst_query -> referent -> fly_to_location test for
repeated-space and long station names, and documents the rule in
docs/CURRENT-STATE.md.

 - **Camera verbs** (`src/cameraVerbs.js`) — one motion slot, driven per clock tick. `move_camera` orbits/pans/tilts/rotates; `fly_route` is a cinematic dolly along an existing route annotation. `rotate_globe` rotates the world-space camera rigidly around Earth's center using its screen-up axis, preserving geocentric range and framing. Left/right describe visible globe motion, while `rotate` turns the camera in place. Omitted globe direction/mode default to right/continuous; explicit values prevail. Other camera motions keep their once default. Admission requires 3D, no Cockpit/tracking owner and the whole globe inside the existing keyhole circle, using the shared keyhole/projection geometry and vertical camera FOV with a rotation-local bounding-sphere cone for off-axis containment. Canvas-edge clipping alone does not block a rigid rotation or its unchanged Globe View preset. There is no altitude cutoff. An already smaller, fully framed globe rotates directly; repeated nudges, direction and speed changes recheck current framing without demanding a reset merely because ellipsoid altitude varied. A close-up or overlap refuses without moving the camera. When the unchanged Globe View preset fits, voice says “Globe rotation isn’t available from this view. You can say ‘Reset to Globe View and rotate the globe.’” without asking a permission question or automatically resetting. Explicit Reset/Show Globe View commands remain direct; an explicit reset-and-rotate request waits for reset success before requesting rotation. If OpenAI dispatches both tools together, rotation waits for earlier same-response resets and is skipped if any fails or is cancelled. OpenAI rejects later tool calls in the same response after a globe refusal, including calls arriving while globe admission is pending, and preserves response-scoped `tool_choice: none` for the refusal follow-up; Gemini rejects further tool execution, including queued sibling calls, until fresh typed input or admitted speech. Model interruption, advisory captions and microphone toggles do not release that guard. There is no pending Yes/No offer. Outside the refused response, explicit-command interpretation and avoiding repeated resets remain model-guided; a distinct model-issued reset call is not an app-enforced proof of user intent. A failed standalone reset can still be retried by the model, and a reset result does not guarantee the camera has fully settled. Before suggesting a reset, a cloned camera checks the unchanged Globe View destination against the same keyhole/depth rules without moving the live camera. If that preset cannot fit, `globe-reset-unavailable` asks for further zoom and the refusal instructs further zoom instead of a reset; this also covers ultrawide views. Unsupported view geometry or non-WGS84 projection assumptions fail closed without the closer-zoom instruction. Supported camera inputs/navigation intents cancel rotation before their action. Finite radius greater than the ellipsoid's maximum radius proves whole-arc clearance at constant centre-distance; no low-altitude swept solver is needed. The unchanged Globe View reset preset remains 18,000,000 m. Terrain and buildings remain outside the guarantee.
   - **The route dolly is shaped, not linear** (2026-08-20). A trapezoid speed profile (smoothstep up, cruise, smoothstep down, distance taken as the closed-form integral) eases both ends without changing the pace — duration is still `totalM / ROUTE_M_S[speed]`, with one exception: a 0.5 s minimum keeps a degenerate route from being an instant teleport, so routes under 10 m (slow) / 20 m (normal) / 45 m (fast) fly SLOWER than the speed word, never faster. Turns bank up to **10°** (a 90° street corner settles near 7.5°), measured as a triangular pulse over a 4 s window centred on the camera so the roll leads in and unwinds after. Altitude breathes ±20 m around the 260 m mean and lifts up to 26 m into turns. Pitch is LOCKED at −32°; heading comes from a gaze that leads the path by 6.5 s of travel. `prefers-reduced-motion` zeroes the roll and the altitude shaping and keeps the easing.

Subject: [PATCH 014/113] fix(tools): wrap whole-degree headings at 360 to 0

The query tools rounded courses, headings, bearings and azimuths with
Number(value.toFixed(0)) and no wrap, so a direction of 359.5 degrees or
more came back as 360: find_vessel with course 359.7 and heading 359.6
returned course_deg 360 and heading_deg 360.

Round them through the shared roundHeadingDegrees helper the layers and
UI already use (src/data/headingDegrees.js), which wraps into 0 to 359:
course_deg and heading_deg (vessels), course_deg (aircraft), bearing_deg
(transit), heading_deg (cameras), and rise_azimuth_deg and azimuth_deg
(satellites). Other rounding is unchanged.

Subject: [PATCH 017/113] test(nominatim): check cache file modes only where
 POSIX modes exist

The disk-cache test asserts the cache directory is 0o700 and its files
0o600. Windows has no POSIX mode bits (the directory stats as 0o666), so
the test always failed there. Both checks now run only off Windows, as
localServices.test.mjs and mcpPanelKey.test.mjs already do for their
0o600 checks. The cache code is unchanged.

Subject: [PATCH 019/113] fix(firms): stop requesting the retired Suomi NPP
 source

NASA stopped delivering Suomi NPP data on 2026-11-02 (FIRMS news page).
With a live MAP_KEY on 2026-11-04, VIIRS_SNPP_NRT came back ok with zero
rows while NOAA-20, NOAA-21 and MODIS returned 57k, 49k and 11k, so the
source only spent one transaction per refresh. The proxy now requests
NOAA-20, NOAA-21 and MODIS NRT. The "N" satellite label stays, so cached
or archived Suomi NPP rows still read SNPP.

Tests count sources from the list instead of assuming four, and a
regression test keeps the retired source out of the production list.

Refs #849

Subject: [PATCH 021/113] fix(perimeters): show a 0.25-acre fire as 0.25 ac,
 not 0 ac

The incident card rounded the WFIGS size to whole acres, so every fire
under half an acre read "0 ac". The live perimeter feed carries many of
these (0.01 to 0.37 acres). Sizes under one acre now keep the reported
hundredths.

Subject: [PATCH 023/113] test(firms): pin the refresh call count and read
 sources from production

Review follow-up for #1552:
- environmentProviders: assert exactly 3 upstream calls per refresh again,
  so a returning fourth source would fail the test.
- firmsProxy: build the test's SOURCES from server/providers/firms.js, so
  there is one list instead of a mirrored copy.
- firmsProxy: drop the unused fourth count entry.

Subject: [PATCH 024/113] Say why Transit and Bike Share rows are empty outside
 coverage
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Over a city with no feed or system (London, Tokyo) both rows read
"ON · — · never", the same as a feed that never answered. Transit already
computed a coverage note but put it only in `coverage`, which the row does
not show; Bike Share reported nothing at all.

Both layers now report a `zoom-in` guidance status with a `statusMessage`:
"Fly below 3,000 km to a covered region" / "No feed here yet · N regions
available" for Transit, and "Fly below 48 km to a covered city" / "No bike
share here yet · N systems available" for Bike Share. A loading or failed
Bike Share city keeps its own text. Leaving coverage clears the layer's
last-update time, so the row no longer dates data it no longer draws.

The coverage-note translations move from the voice card into
`translateStatusMessage` (ui/statusText.js), which the Layers row and the
voice card now share.

Subject: [PATCH 026/113] Hide a vessel's detection callout while its own card
 paints

With Vessels and Detection on, a vessel with an ambient card on the map
also got its detection callout next to the bracket. The callout lane
paints beneath the cards, so its text showed through the card's plate
and covered the speed and course.

The callout now gives way only to a card the shared overlay actually
paints in the same frame. The overlay paints part of the published
cards (shared budget, collisions, UI chrome), so a vessel whose card
was dropped keeps its callout.

The detection lane paints before the cards publish their paint rects,
so getOverlayPaintRect has nothing for the current frame there. The new
isOverlayEntryQueued answers from the paint queue that the overlay
solves before painting. Vessel detection objects name their card in
cardSourceId/cardEntryId.

   Mission world text has no native `LabelGraphics`: overview launch markers publish at most 48 ambient candidates for a 24-winner budget, while selecting a mission clears that overview source and publishes its launch-site callout, stage re-entry annotations, live/estimated payload-position readout, and orbit annotation as protected selected-lane entries. The source retains the exact former strings and colors. Static anchors reuse the Cartesian values used to build their mission geometry; the moving payload entry reads the layer's per-frame live-position cache; catalog-backed orbit annotation positions are cached in the same one-second matrix update that realigns the orbit primitive. Keyhole edge fade, horizon culling, final collision placement, and UI exclusion are owned by the shared host. Deselect restores the bounded overview, and refresh, disable, and destroy replace or clear both mission sources.
   A selected mission renders its orbit as four repeating tactical sectors, each containing one prominent cyan dot followed by one hundred thin translucent dashes. The bright dots act as orbit anchors while the subdued dash field remains depth-tested against the globe and is shown only for the selected mission.
   Close selected-pad views add one static 500 m-radius cyan launch-zone ring with a low-opacity translucent fill over the sampled photoreal launch-site surface. The single scene primitive is created only for the visible selected site and is otherwise dormant. It appears during Focus, sufficiently close manual zoom, and the replay countdown, but is suppressed above 120 km camera altitude, beyond 180 km direct camera-to-pad range, for unselected missions, and whenever Space Missions is inactive. Focus establishes a launch-site-centered camera transform once; subsequent manual heading and pitch changes remain centered on that site without an automated per-frame correction. Surface mission markers and labels use an additional conservative globe-limb margin before the exact ellipsoid occluder boundary, preventing near-horizon visibility from alternating between frames.
-- **AIS vessels**: chevron symbology (naval cyan base, type tints), world-space headings, MMSI-keyed reconciliation (selection survives refreshes; pinned 3 refreshes with STALE marker when absent), detection-overlay integration (`type: 'SEA'`), contextStore registration for voice Q&A. Empty-space clicks, id-less photorealistic-tile picks, and Escape dismiss the vessel card/HUD/context and clear its trail; picks owned by another layer (including `gev-trail:*`) and raw vessel-record picks without a live MMSI key are no-ops for vessel selection. Click and key handlers detach while the layer is disabled and reinstall on enable. Selecting another vessel replaces the selection and trail, and reconciliation clears a trail if its owning vessel is evicted.

 - **Track trails**: server accumulates per-MMSI ring buffers (`/api/vessels/track?mmsi=`, Float32+Uint32, 64 samples, 30s/25m thinning); aircraft backfill proxies `/api/flights/track` (OAuth, own credit bucket). Military aircraft keep only their locally accumulated trails: `/api/military/track` validates the hex, then answers `503 history_unavailable` without an upstream request.
 - Shared `src/data/pickRegistry.js` stops the two flight layers' click handlers from fighting over the camera.

Subject: [PATCH 028/113] Keep the queued-card check off the per-frame
 allocation path

Writing a fractional alpha onto the overlay record for every paint item
boxed a heap number per item per frame. The allocation gate caught it:
the generic 60-entry workload went from 2,838 to 12,614 B/frame. The
record now keeps only the frame stamp and a pointer to its paint item,
and isOverlayEntryQueued multiplies the alphas when it is asked. The
gate is back to main's numbers on Node 24.

 - **Cockpit camera anchor:** first-person mode does not write feed-boundary corrections directly into the camera. A cockpit-only inertial anchor advances from the selected aircraft's displayed course and speed, then converges toward the authoritative delayed track with correction capped below forward motion. The displayed kinematics are derived from the same consecutive fix segment as the rendered position, with raw feed speed/course used only as fallback; a transient zero/missing feed speed therefore cannot freeze a visibly moving aircraft after layer enable or a map/cockpit handoff. Rendered altitude continues to come from that interpolated track position. Late ADS-B fixes and short render stalls can remove drift without accelerating or reversing the view. Camera placement runs before scene update/culling at a bounded 20 Hz so a moving cockpit does not force Photoreal 3D Tiles to retraverse on every display frame; textual instruments update at 10 Hz and context/layout work at 4 Hz. Every far Cockpit contact pip shares one stable Cesium texture-atlas entry and skips unused screen-projected course calculations, while only in-range 2D aircraft silhouettes pay the screen-projected rotation cost; ambient glTF collections are hidden/retained rather than synchronously destroyed at cockpit entry, and context rails lay out only on explicit content/state changes and viewport resize. The deliberate 15/30-second layer interpolation delays and per-Cesium-frame position caches remain unchanged.
 - **Cockpit route, vision, and view controls:** visible on-screen `COCKPIT`, `RESET`, and `EXIT COCKPIT` controls replace reliance on the `C` shortcut. RESET uses the same canonical globe route as the map and voice actions, exits Cockpit, and releases its camera ownership rather than exposing the hidden map-style top action. When the tracked commercial flight has a plausible ADSBDB route, the top of the right briefing rail shows a compact `FROM → TO` airport strip and the visor shows a centered estimated-destination chevron with its relative bearing; its destination label rounds to whole degrees in 000–359, wrapping rounded north to 000° while the chevron continues to use the relative bearing independently of label rounding; absent or implausible route data hides the strip and cue rather than guessing. The cockpit-local vision control is an interactive `PREV / CURRENT / NEXT` carousel over `NORMAL`, `CRT`, `NVG`, `FLIR`, `ANIME`, and `NOIR`; its previous/next actions wrap, and activating the current value advances to the next style. Cockpit enters on the active map preset, so a Cyber FLIR map opens Cockpit on FLIR while Normal remains a distinct option instead of producing a second FLIR entry. Cockpit choices temporarily activate the existing Cesium post-process stages, while exiting Cockpit through either EXIT or RESET restores the pre-entry map style. The regional-news page uses a free Google News RSS locality query first, with the existing GDELT query retained only as a fail-soft fallback; linked headlines remain reporting, not verified incidents or risk intelligence.
 - Cockpit wind-direction labels wrap after rounding to whole degrees, so a direction of 359.5° displays as `N · 0°` rather than `N · 360°`.
-- The transit, ALPR, vessel, CCTV, Local ADS-B, flight and military context, awareness, Cockpit and Street Level heading readouts round through `roundHeadingDegrees` in `src/data/headingDegrees.js` (whole degrees 0–359, `null` when not finite, so each caller keeps its own placeholder); `normalizeHeading` lives there too and `cockpitMath.js` re-exports it. The Cockpit's `TRACK ACQUIRED` signal uses `formatHeadingReadout`, so a 359.6° track reads `COURSE 000°`.

The Cockpit's `TRACK ACQUIRED` signal uses `formatHeadingReadout`, so a 359.6° track reads `COURSE 000°`.
 - **Cockpit missing observations:** missing local weather observations remain unknown rather than being converted to zero or clear skies, in the briefing and in the cloud effects; a missing temperature drops the whole local weather record, including its wind and condition.
 - **Cockpit weather status:** the earlier multi-canvas atmospheric compositor remains fail-closed and is not attached to the live viewer. Cockpit clouds are a separate transparent WebGL pass with a capped 520×320 framebuffer, 24 ray steps, three FBM octaves, and a 12 FPS ceiling. It defaults off and starts only when local storage explicitly contains the persisted `WX ON` opt-in (`'1'`). When opted in, observations refresh after five minutes or 25 km of aircraft movement, fail transparent when unavailable or clear, and stop on exit or disable. `WX OFF` governs atmospheric rendering only: the briefing still fetches source-backed Natural Earth region, headline, and Open-Meteo local-information data, aborting and replacing any in-flight request when the selected aircraft changes. No weather effect runs in map mode and no synthetic fallback is shown.
 - **Cockpit trail visibility:** entering cockpit hides the selected aircraft's trail body and head so they cannot cross the first-person view; exit restores them. This cockpit-only presentation change does not alter the normal map-mode invariant that aircraft trails render through terrain using their depth-fail material.

Subject: [PATCH 031/113] Fade a vessel's callout by its card's painted opacity

The callout now asks for the opacity its own card paints with this frame,
keyhole fade included, and fades out as the card fades in. A card faded out
at the keyhole rim leaves the callout readable, and a card fading out after
leaving its source still hides it. The vessel card id is cached on the
record, and the allocation gate covers the lookup.

Static anchors reuse the Cartesian values used to build their mission geometry; the moving payload entry reads the layer's per-frame live-position cache; catalog-backed orbit annotation positions are cached in the same one-second matrix update that realigns the orbit primitive. Keyhole edge fade, horizon culling, final collision placement, and UI exclusion are owned by the shared host. Deselect restores the bounded overview, and refresh, disable, and destroy replace or clear both mission sources.
   A selected mission renders its orbit as four repeating tactical sectors, each containing one prominent cyan dot followed by one hundred thin translucent dashes. The bright dots act as orbit anchors while the subdued dash field remains depth-tested against the globe and is shown only for the selected mission.
   Close selected-pad views add one static 500 m-radius cyan launch-zone ring with a low-opacity translucent fill over the sampled photoreal launch-site surface. The single scene primitive is created only for the visible selected site and is otherwise dormant. It appears during Focus, sufficiently close manual zoom, and the replay countdown, but is suppressed above 120 km camera altitude, beyond 180 km direct camera-to-pad range, for unselected missions, and whenever Space Missions is inactive. Focus establishes a launch-site-centered camera transform once; subsequent manual heading and pitch changes remain centered on that site without an automated per-frame correction. Surface mission markers and labels use an additional conservative globe-limb margin before the exact ellipsoid occluder boundary, preventing near-horizon visibility from alternating between frames.
-- **AIS vessels**: chevron symbology (naval cyan base, type tints), world-space headings, MMSI-keyed reconciliation (selection survives refreshes; pinned 3 refreshes with STALE marker when absent), detection-overlay integration (`type: 'SEA'`; a vessel whose ambient card the shared host paints in the current frame draws no detection callout, because the callout would show through the card's plate, while a vessel whose card was published but not painted (shared budget, collisions, UI chrome) keeps its callout — its detectable object names the card in `cardSourceId`/`cardEntryId`, and the callout lane asks `isOverlayEntryQueued` in `src/overlays/worldOverlay.js`, which answers from the solved paint queue because the detection lane paints before the cards publish their paint rects), contextStore registration for voice Q&A. Empty-space clicks, id-less photorealistic-tile picks, and Escape dismiss the vessel card/HUD/context and clear its trail; picks owned by another layer (including `gev-trail:*`) and raw vessel-record picks without a live MMSI key are no-ops for vessel selection. Click and key handlers detach while the layer is disabled and reinstall on enable. Selecting another vessel replaces the selection and trail, and reconciliation clears a trail if its owning vessel is evicted.
+- **AIS vessels**: chevron symbology (naval cyan base, type tints), world-space headings, MMSI-keyed reconciliation (selection survives refreshes; pinned 3 refreshes with STALE marker when absent), detection-overlay integration (`type: 'SEA'`; a vessel's detection callout fades out while its own ambient card paints in the same frame, judged by the card's painted opacity including the keyhole fade, so a card dropped by budget, collisions or UI chrome, or faded out at the keyhole rim, leaves the callout readable), contextStore registration for voice Q&A. Empty-space clicks, id-less photorealistic-tile picks, and Escape dismiss the vessel card/HUD/context and clear its trail; picks owned by another layer (including `gev-trail:*`) and raw vessel-record picks without a live MMSI key are no-ops for vessel selection. Click and key handlers detach while the layer is disabled and reinstall on enable. Selecting another vessel replaces the selection and trail, and reconciliation clears a trail if its owning vessel is evicted.
 - **Track trails**: server accumulates per-MMSI ring buffers (`/api/vessels/track?mmsi=`, Float32+Uint32, 64 samples, 30s/25m thinning); aircraft backfill proxies `/api/flights/track` (OAuth, own credit bucket). Military aircraft keep only their locally accumulated trails: `/api/military/track` validates the hex, then answers `503 history_unavailable` without an upstream request.
 - Shared `src/data/pickRegistry.js` stops the two flight layers' click handlers from fighting over the camera.

Subject: [PATCH 032/113] Name the real gate altitude and repaint coverage rows
 at once

The Transit prompt said "Fly below 3,000 km", but the closed gate opens at
2,850 km; it now names the enter threshold, as Bike Share does. When the
camera changes coverage, Transit and Bike Share ask the Layers panel to
repaint instead of leaving the old prompt up until the next 15 s / 60 s tick.

Subject: [PATCH 033/113] feat(transit): add Szczecin buses and trams (ZDiTM,
 CC0)

Keyless GTFS-Realtime feed published by ZDiTM Szczecin under CC0 1.0.
Speeds are m/s (checked against vehicle movement), the file refreshes about
every 20 s, and the feed carries no route ids, so vehicles take the default
bus mode.

 - **Houston TranStar cameras.** Keyless. The camera list is the public `traffic.houstontranstar.org/data/layers/cctvSnapshots_json.js` catalog (~1,000 cameras across Greater Houston); frames are stills at `www.houstontranstar.org/snapshots/cctv/<id>.jpg`, synthesized from a validated numeric id rather than taken from the payload, and only that host is registered. Cameras whose catalog id is `0` (a different, non-snapshot class) and cameras outside Greater Houston are dropped. TranStar's `dir` field is the side of the freeway the camera sits on, not the way it faces: TranStar's own map shows it as "Traffic closest to the camera is traveling …" (South → eastbound, North → westbound, West → southbound, East → northbound). That travel direction (90°, 270°, 180°, 0°) seeds the heading as a low-confidence prior with the low-confidence pose; `None` or an unknown value uses the shared id-hash fallback at low confidence. Headings are corrected with the in-app calibration gizmo. Off by default. TranStar's [Content Usage terms](https://traffic.houstontranstar.org/disclaimer.aspx) prohibit copying or distributing the site's information, and external framing or linking to specific images, without TxDOT's prior written permission; its FAQ grants permission-free use only for the RSS feeds. This project does not hold that permission for downstream installations, so the pack loads only when an operator who holds TxDOT's written permission sets `CCTV_HOUSTON_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to TranStar. Once enabled, it loads the 250 cameras nearest downtown, Uptown, the Medical Center, IAH and Galveston; `CCTV_HOUSTON_MAX_SOURCES` (8–400) changes the cap. Snapshots update about every 3 minutes, which is also the ambient still cadence. Frames are fetched from TranStar and relayed to the browser on demand, buffered only transiently per request, sent with `Cache-Control: no-store`, and not archived.
 - **Autostrada del Brennero (A22) webcams.** Keyless. The camera list is one request to the Open Data Hub tourism API (`tourism.api.opendatahub.com/v1/WebcamInfo?source=a22`), run by NOI Techpark in South Tyrol, which republishes Autobrennero's own list of 13 motorway webcams with coordinates and kilometre markers. Frames are the operator's stills on `www.autobrennero.it/WebCamImg/km<N>.jpg`, refreshed about once a minute, and only the exact image for each camera's kilometre is registered. The feed names no bearing, so headings use the id-hash fallback at low confidence. The road climbs from about 20 m in the Po valley to about 1,370 m at the Brenner Pass, so each camera's ground elevation comes from a per-kilometre table sampled from the Copernicus GLO-90 DEM (via Open-Meteo's elevation API); a camera not in the table uses a 200 m prior. The Open Data Hub tags every record CC0 (`ClosedData: false`, Autobrennero as licence holder), but that tag is the aggregator's metadata and Autobrennero publishes no terms of its own for the images, so they are credited to the operator as a courtesy and are not redistributed. Frames are fetched at request time and never stored. Disable with `CCTV_A22_ENABLED=0`.
 - **Camera frame content.** Public camera frames can contain people, vehicles and license plates, and the camera layer does nothing with them beyond putting them on the map. A successful upstream response is relayed as the provider served it: nothing in the camera pipeline blurs, redacts, enhances or restores it, and nothing there runs face, plate or object detection or otherwise recognises or classifies what is in the picture. (The ALPR layer described below maps where plate-reader cameras are, from locations contributors tagged in OpenStreetMap; it reads nothing from any camera frame.) When an upstream has no frame for a camera, what you see instead is a Google Street View still or the app's own placeholder card; the panel's source badge names which of them you are looking at, and a refresh that fails after a frame has arrived leaves the last good picture on screen rather than replacing it. The browser resamples each frame for display: onto a fixed 1920x1080 surface for the camera's projection plane in the scene, and onto a 192x108 canvas for the small ambient card. That scaling is the only change made to the picture, and the only pixels the camera layer reads back are a 64x36 downscale hashed to tell whether the picture has changed. Live streams are piped through; the still path reads the image into memory to pass it on — TxDOT wraps its JPEG in a JSON envelope, which is decoded there — and no frame is written to disk (the disk cache, `.gev-cache/`, holds feed JSON for other layers and never camera imagery). Outside that pipeline, the voice assistant is the one feature that sends imagery anywhere: when it answers a question about what is in view it may attach a downscaled screenshot of the rendered scene — including any camera plane on screen — to the request it sends to the voice model. Frames are fetched only from server-registered camera URLs — a client cannot hand the proxy a URL (see [SECURITY.md](SECURITY.md)). What the app does stays inside the line README draws: no named-person search, no face recognition, no tracking individuals.
-- **Transit (GTFS-Realtime).** The proxy requests only registered operator feeds, validates redirects, bounds responses, and uses conditional requests, short snapshot caching and failure backoff. All eighteen registered feeds, covering seventeen regions, are live-enabled; each can be disabled independently. Vehicles use delayed playback between reports, with report age and waiting states shown separately. Session-local selected trails are available for every feed. MBTA additionally retains up to 15 minutes of recently observed positions in the running proxy, so available history can survive a browser reload; server restart clears it. History reads never fetch upstream, and other feeds have no proxy retention. Nothing is archived to disk or collected in the background. Operator text credits are included as a courtesy and do not imply endorsement. Heights are aligned to work with Google 3D tiles; subway markers are shown at street level because these feeds do not supply depth. The TTC feed is BusTime, the surface system: it carries buses and streetcars and no subway at all. About four in ten of its vehicles report no route at all (unassigned or deadheading), and those are shown with the feed default rather than a route-established mode. It sends no ETag or Last-Modified, so its conditional requests fall through to the ordinary snapshot cache. Three Golden Horseshoe neighbours run alongside it — MiWay, Hamilton HSR and Durham Region Transit — each bus-only and each polled only near its own region. Durham Region Transit publishes no bearing on any vehicle, so those sprites take their heading from observed movement like any other feed that omits it. Guelph, Kingston and Barrie extend the same pattern eastward and north. Hamilton, Guelph, Burlington, YRT and Rio’s SMTR publish route ids that are not the number on the vehicle, so those entries carry a route-name table taken from each operator’s own published GTFS; any id missing from a table renders unchanged rather than blank. A label is never invented: YRT runs a route `9101` that appears nowhere in its published routes, so it stays as the feed sends it. Burlington’s is the one that cannot be shortcut: `351` is route 1 while `3510` is route 10, so the table is a real join rather than a trimmed prefix. GO Transit / Metrolinx is deliberately absent: its REALTIME feed requires an API key issued by manual review, which the keyless admission rule excludes (its static schedule download is keyless, but carries no vehicle positions). Barrie and YRT/Viva each invite acceptance of their licence through a form, and each licence also states that using the data is itself acceptance; this deployment relies on that clause, which is recorded in both entries. Grand River Transit in Waterloo is absent for a different reason: it answers, but its feed header was months stale and it publishes no per-vehicle timestamps, so it would render vehicles that look live and are not. Ottawa’s OC Transpo falls to the same keyless admission rule as GO Transit — its realtime feed requires an API key. London Transit and Thunder Bay Transit publish vehicle positions over plain HTTP with no HTTPS endpoint available. Every other Ontario system — Brampton, Oakville, Niagara, Milton, Windsor, Greater Sudbury, UP Express and a dozen smaller operators — publishes static GTFS schedules only, with no realtime vehicle positions to register. Between the nine included and these exclusions, every Ontario realtime vehicle-position feed catalogued in the Mobility Database is accounted for.

 - **Radio country coverage (optional).** Set `RADIO_PRIORITY_COUNTRIES=IN,PL` in the local `.env` and restart to include stations beyond the global click charts. The operator may choose up to eight unique ISO alpha-2 country codes; no key is needed. Each country adds one bounded query (at most 200 rows) and reserves up to 40 unique, usable stations inside the existing 750-station catalog. Country seeds precede specialist-tag seeds and global popularity fill; unused slots return to the shared pool. This is a coverage preference, not an exhaustive national directory or a guarantee of stations in every city. Countries with no eligible HTTPS MP3/AAC geolocated stations remain empty. An unset list preserves global selection. Country requests share the directory cache and three-worker pool; failed country queries are reported in coverage without blocking a healthy global refresh. Failed/degraded refreshes back off for one minute, with at most three mirrors per query.
 
 - **Radio Browser.** In every installation, including when `RADIO_PRIORITY_COUNTRIES` is unset, each request tries at most three mirror candidates (later fallback candidates are skipped), and failed or partial catalog refreshes back off for 60 seconds. A cold-start failure therefore continues returning 503 during that delay even if upstream recovers. `/api/radio/stations` discovers official API mirrors, makes bounded and coalesced healthy/geolocated HTTPS-station queries, caches the normalized public-domain directory for 45 minutes, and may serve the last good catalog for up to seven days during an outage. Refreshes must meet minimum accepted-query and station coverage before replacing a warm catalog; broad/specialist responses whose rows all fail the product's health policy do not count as successful queries. Optional priority-country outcomes are advisory: valid, in-limit responses with no eligible stations succeed as empty results, while failed or malformed country queries report unsuccessful coverage without degrading the global catalog. A usable partial cold catalog is explicitly `DEGRADED`, and non-array or empty broad/specialist payloads are rejected atomically. Individual structurally malformed rows are skipped rather than failing the whole query; the response carries their bounded `rejectedStationCount` (at most 10,000), which the client adds to its own rejected rows and reports as degraded coverage without discarding the accepted generation. Every directory and click-count request rejects redirects, validates all resolved addresses as globally routable (including reserved/documentation IPv4 and special/non-global IPv6 exclusions), and pins the TLS connection to a validated address. Only MP3/AAC non-HLS directory rows with public HTTPS stream targets are returned; favicons are intentionally omitted. Pressing play connects one browser audio element directly to the selected broadcaster and calls the directory's click counter through known-ID-only `POST /api/radio/click/:uuid`. GEV never proxies, caches, records, bundles, or redistributes audio. Radio Browser supplies station-level tags, not dependable current-song or upcoming-program metadata, so Radio filtering never claims either. Direct playback exposes the listener's IP address to the broadcaster, whose own stream terms apply.

Subject: [PATCH 034/113] Prune queued-card rows whose pooled item paints
 another entry

A pooled paint item reused by another card keeps a fresh frame stamp, so
rows for cards that stopped painting survived every prune and the index
grew for the whole session. The prune now also drops a row whose item
paints a different entry id or source, and a test pins the bound.

   Mission world text has no native `LabelGraphics`: overview launch markers publish at most 48 ambient candidates for a 24-winner budget, while selecting a mission clears that overview source and publishes its launch-site callout, stage re-entry annotations, live/estimated payload-position readout, and orbit annotation as protected selected-lane entries. The source retains the exact former strings and colors. Static anchors reuse the Cartesian values used to build their mission geometry; the moving payload entry reads the layer's per-frame live-position cache; catalog-backed orbit annotation positions are cached in the same one-second matrix update that realigns the orbit primitive. Keyhole edge fade, horizon culling, final collision placement, and UI exclusion are owned by the shared host. Deselect restores the bounded overview, and refresh, disable, and destroy replace or clear both mission sources.
   A selected mission renders its orbit as four repeating tactical sectors, each containing one prominent cyan dot followed by one hundred thin translucent dashes. The bright dots act as orbit anchors while the subdued dash field remains depth-tested against the globe and is shown only for the selected mission.
   Close selected-pad views add one static 500 m-radius cyan launch-zone ring with a low-opacity translucent fill over the sampled photoreal launch-site surface. The single scene primitive is created only for the visible selected site and is otherwise dormant. It appears during Focus, sufficiently close manual zoom, and the replay countdown, but is suppressed above 120 km camera altitude, beyond 180 km direct camera-to-pad range, for unselected missions, and whenever Space Missions is inactive. Focus establishes a launch-site-centered camera transform once; subsequent manual heading and pitch changes remain centered on that site without an automated per-frame correction. Surface mission markers and labels use an additional conservative globe-limb margin before the exact ellipsoid occluder boundary, preventing near-horizon visibility from alternating between frames.
-- **AIS vessels**: chevron symbology (naval cyan base, type tints), world-space headings, MMSI-keyed reconciliation (selection survives refreshes; pinned 3 refreshes with STALE marker when absent), detection-overlay integration (`type: 'SEA'`; a vessel's detection callout fades out while its own ambient card paints in the same frame, judged by the card's painted opacity including the keyhole fade, so a card dropped by budget, collisions or UI chrome, or faded out at the keyhole rim, leaves the callout readable), contextStore registration for voice Q&A. Empty-space clicks, id-less photorealistic-tile picks, and Escape dismiss the vessel card/HUD/context and clear its trail; picks owned by another layer (including `gev-trail:*`) and raw vessel-record picks without a live MMSI key are no-ops for vessel selection. Click and key handlers detach while the layer is disabled and reinstall on enable. Selecting another vessel replaces the selection and trail, and reconciliation clears a trail if its owning vessel is evicted.

Military aircraft keep only their locally accumulated trails: `/api/military/track` validates the hex, then answers `503 history_unavailable` without an upstream request.
 - Shared `src/data/pickRegistry.js` stops the two flight layers' click handlers from fighting over the camera.

Subject: [PATCH 043/113] feat(transit): add Lisbon's Carris Metropolitana
 buses

Keyless GTFS-Realtime feed from Carris Metropolitana, documented in the
operator's public API repository. No licence is stated for the realtime
endpoint (the static GTFS is CC BY 4.0), so it is credited as a courtesy on
the same basis as the Metro Transit and OVapi feeds. The feed publishes km/h,
so a new `speedUnit` registry field lets the proxy convert to m/s. Route ids
wrap the GTFS route id in an area prefix and are read as the line number.

 - **Houston TranStar cameras.** Keyless. The camera list is the public `traffic.houstontranstar.org/data/layers/cctvSnapshots_json.js` catalog (~1,000 cameras across Greater Houston); frames are stills at `www.houstontranstar.org/snapshots/cctv/<id>.jpg`, synthesized from a validated numeric id rather than taken from the payload, and only that host is registered. Cameras whose catalog id is `0` (a different, non-snapshot class) and cameras outside Greater Houston are dropped. TranStar's `dir` field is the side of the freeway the camera sits on, not the way it faces: TranStar's own map shows it as "Traffic closest to the camera is traveling …" (South → eastbound, North → westbound, West → southbound, East → northbound). That travel direction (90°, 270°, 180°, 0°) seeds the heading as a low-confidence prior with the low-confidence pose; `None` or an unknown value uses the shared id-hash fallback at low confidence. Headings are corrected with the in-app calibration gizmo. Off by default. TranStar's [Content Usage terms](https://traffic.houstontranstar.org/disclaimer.aspx) prohibit copying or distributing the site's information, and external framing or linking to specific images, without TxDOT's prior written permission; its FAQ grants permission-free use only for the RSS feeds. This project does not hold that permission for downstream installations, so the pack loads only when an operator who holds TxDOT's written permission sets `CCTV_HOUSTON_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to TranStar. Once enabled, it loads the 250 cameras nearest downtown, Uptown, the Medical Center, IAH and Galveston; `CCTV_HOUSTON_MAX_SOURCES` (8–400) changes the cap. Snapshots update about every 3 minutes, which is also the ambient still cadence. Frames are fetched from TranStar and relayed to the browser on demand, buffered only transiently per request, sent with `Cache-Control: no-store`, and not archived.
 - **Autostrada del Brennero (A22) webcams.** Keyless. The camera list is one request to the Open Data Hub tourism API (`tourism.api.opendatahub.com/v1/WebcamInfo?source=a22`), run by NOI Techpark in South Tyrol, which republishes Autobrennero's own list of 13 motorway webcams with coordinates and kilometre markers. Frames are the operator's stills on `www.autobrennero.it/WebCamImg/km<N>.jpg`, refreshed about once a minute, and only the exact image for each camera's kilometre is registered. The feed names no bearing, so headings use the id-hash fallback at low confidence. The road climbs from about 20 m in the Po valley to about 1,370 m at the Brenner Pass, so each camera's ground elevation comes from a per-kilometre table sampled from the Copernicus GLO-90 DEM (via Open-Meteo's elevation API); a camera not in the table uses a 200 m prior. The Open Data Hub tags every record CC0 (`ClosedData: false`, Autobrennero as licence holder), but that tag is the aggregator's metadata and Autobrennero publishes no terms of its own for the images, so they are credited to the operator as a courtesy and are not redistributed. Frames are fetched at request time and never stored. Disable with `CCTV_A22_ENABLED=0`.
 - **Camera frame content.** Public camera frames can contain people, vehicles and license plates, and the camera layer does nothing with them beyond putting them on the map. A successful upstream response is relayed as the provider served it: nothing in the camera pipeline blurs, redacts, enhances or restores it, and nothing there runs face, plate or object detection or otherwise recognises or classifies what is in the picture. (The ALPR layer described below maps where plate-reader cameras are, from locations contributors tagged in OpenStreetMap; it reads nothing from any camera frame.) When an upstream has no frame for a camera, what you see instead is a Google Street View still or the app's own placeholder card; the panel's source badge names which of them you are looking at, and a refresh that fails after a frame has arrived leaves the last good picture on screen rather than replacing it. The browser resamples each frame for display: onto a fixed 1920x1080 surface for the camera's projection plane in the scene, and onto a 192x108 canvas for the small ambient card. That scaling is the only change made to the picture, and the only pixels the camera layer reads back are a 64x36 downscale hashed to tell whether the picture has changed. Live streams are piped through; the still path reads the image into memory to pass it on — TxDOT wraps its JPEG in a JSON envelope, which is decoded there — and no frame is written to disk (the disk cache, `.gev-cache/`, holds feed JSON for other layers and never camera imagery). Outside that pipeline, the voice assistant is the one feature that sends imagery anywhere: when it answers a question about what is in view it may attach a downscaled screenshot of the rendered scene — including any camera plane on screen — to the request it sends to the voice model. Frames are fetched only from server-registered camera URLs — a client cannot hand the proxy a URL (see [SECURITY.md](SECURITY.md)). What the app does stays inside the line README draws: no named-person search, no face recognition, no tracking individuals.
-- **Transit (GTFS-Realtime).** The proxy requests only registered operator feeds, validates redirects, bounds responses, and uses conditional requests, short snapshot caching and failure backoff. All nineteen registered feeds, covering eighteen regions, are live-enabled; each can be disabled independently. Vehicles use delayed playback between reports, with report age and waiting states shown separately. Session-local selected trails are available for every feed. MBTA additionally retains up to 15 minutes of recently observed positions in the running proxy, so available history can survive a browser reload; server restart clears it. History reads never fetch upstream, and other feeds have no proxy retention. Nothing is archived to disk or collected in the background. Operator text credits are included as a courtesy and do not imply endorsement. Heights are aligned to work with Google 3D tiles; subway markers are shown at street level because these feeds do not supply depth. The TTC feed is BusTime, the surface system: it carries buses and streetcars and no subway at all. About four in ten of its vehicles report no route at all (unassigned or deadheading), and those are shown with the feed default rather than a route-established mode. It sends no ETag or Last-Modified, so its conditional requests fall through to the ordinary snapshot cache. Three Golden Horseshoe neighbours run alongside it — MiWay, Hamilton HSR and Durham Region Transit — each bus-only and each polled only near its own region. Durham Region Transit publishes no bearing on any vehicle, so those sprites take their heading from observed movement like any other feed that omits it. Guelph, Kingston and Barrie extend the same pattern eastward and north. Hamilton, Guelph, Burlington, YRT and Rio’s SMTR publish route ids that are not the number on the vehicle, so those entries carry a route-name table taken from each operator’s own published GTFS; any id missing from a table renders unchanged rather than blank. A label is never invented: YRT runs a route `9101` that appears nowhere in its published routes, so it stays as the feed sends it. Burlington’s is the one that cannot be shortcut: `351` is route 1 while `3510` is route 10, so the table is a real join rather than a trimmed prefix. GO Transit / Metrolinx is deliberately absent: its REALTIME feed requires an API key issued by manual review, which the keyless admission rule excludes (its static schedule download is keyless, but carries no vehicle positions). Barrie and YRT/Viva each invite acceptance of their licence through a form, and each licence also states that using the data is itself acceptance; this deployment relies on that clause, which is recorded in both entries. Grand River Transit in Waterloo is absent for a different reason: it answers, but its feed header was months stale and it publishes no per-vehicle timestamps, so it would render vehicles that look live and are not. Ottawa’s OC Transpo falls to the same keyless admission rule as GO Transit — its realtime feed requires an API key. London Transit and Thunder Bay Transit publish vehicle positions over plain HTTP with no HTTPS endpoint available. Every other Ontario system — Brampton, Oakville, Niagara, Milton, Windsor, Greater Sudbury, UP Express and a dozen smaller operators — publishes static GTFS schedules only, with no realtime vehicle positions to register. Between the nine included and these exclusions, every Ontario realtime vehicle-position feed catalogued in the Mobility Database is accounted for.

 - **Radio country coverage (optional).** Set `RADIO_PRIORITY_COUNTRIES=IN,PL` in the local `.env` and restart to include stations beyond the global click charts. The operator may choose up to eight unique ISO alpha-2 country codes; no key is needed. Each country adds one bounded query (at most 200 rows) and reserves up to 40 unique, usable stations inside the existing 750-station catalog. Country seeds precede specialist-tag seeds and global popularity fill; unused slots return to the shared pool. This is a coverage preference, not an exhaustive national directory or a guarantee of stations in every city. Countries with no eligible HTTPS MP3/AAC geolocated stations remain empty. An unset list preserves global selection. Country requests share the directory cache and three-worker pool; failed country queries are reported in coverage without blocking a healthy global refresh. Failed/degraded refreshes back off for one minute, with at most three mirrors per query.
 
 - **Radio Browser.** In every installation, including when `RADIO_PRIORITY_COUNTRIES` is unset, each request tries at most three mirror candidates (later fallback candidates are skipped), and failed or partial catalog refreshes back off for 60 seconds. A cold-start failure therefore continues returning 503 during that delay even if upstream recovers. `/api/radio/stations` discovers official API mirrors, makes bounded and coalesced healthy/geolocated HTTPS-station queries, caches the normalized public-domain directory for 45 minutes, and may serve the last good catalog for up to seven days during an outage. Refreshes must meet minimum accepted-query and station coverage before replacing a warm catalog; broad/specialist responses whose rows all fail the product's health policy do not count as successful queries. Optional priority-country outcomes are advisory: valid, in-limit responses with no eligible stations succeed as empty results, while failed or malformed country queries report unsuccessful coverage without degrading the global catalog. A usable partial cold catalog is explicitly `DEGRADED`, and non-array or empty broad/specialist payloads are rejected atomically. Individual structurally malformed rows are skipped rather than failing the whole query; the response carries their bounded `rejectedStationCount` (at most 10,000), which the client adds to its own rejected rows and reports as degraded coverage without discarding the accepted generation. Every directory and click-count request rejects redirects, validates all resolved addresses as globally routable (including reserved/documentation IPv4 and special/non-global IPv6 exclusions), and pins the TLS connection to a validated address. Only MP3/AAC non-HLS directory rows with public HTTPS stream targets are returned; favicons are intentionally omitted. Pressing play connects one browser audio element directly to the selected broadcaster and calls the directory's click counter through known-ID-only `POST /api/radio/click/:uuid`. GEV never proxies, caches, records, bundles, or redistributes audio. Radio Browser supplies station-level tags, not dependable current-song or upcoming-program metadata, so Radio filtering never claims either. Direct playback exposes the listener's IP address to the broadcaster, whose own stream terms apply.

Subject: [PATCH 044/113] feat(transit): add 32 more keyless cities across
 Europe, Asia, Oceania and North America
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Prague, Warsaw, Kraków (buses and trams), Poznań, Gdańsk, Rzeszów, Vilnius,
Bucharest, Cluj-Napoca, Iași, Rome, Turin, Venice (buses and waterbuses),
Bordeaux, Montpellier, Rouen, Toulon, Le Havre, Tours, Málaga, Lisbon's city
Carris, Sendai, Johor Bahru, Kota Bharu, Adelaide, Atlanta, Denver, Edmonton,
Halifax and Victoria.

Each entry records its licence, or that none is stated and the Metro
Transit/OVapi basis it ships on. Montpellier and Toulon publish km/h and are
converted. Route ids are read as the rider-facing line; Prague, Bordeaux and
Le Havre trams and Venice waterbuses take their own mode. Adelaide needs
`Accept: */*` to get binary protobuf. Every feed was fetched through the dev
proxy on 2026-11-08.

 | **SMTR Rio de Janeiro** (dados.mobilidade.rio) | Transit layer live vehicles, Rio de Janeiro: municipal buses (SPPO) and the Mobi-Rio BRT, as two feeds | CC BY 4.0, stated on both data.rio catalog pages. Keyless GTFS-Realtime published by the Secretaria Municipal de Transportes, labelled beta, with a gateway limit of 5 requests a second and 60 a minute. Line names come from SMTR’s GTFS `routes.txt` (dados.mobilidade.rio/gtfs/schedule), under the same licence. | Attribution to SMTR / Prefeitura da Cidade do Rio de Janeiro under CC BY 4.0 |
 | **ZDiTM Szczecin** (zditm.szczecin.pl) | Transit layer live vehicles, Szczecin, Poland: buses and trams as one feed | CC0 1.0, stated on the ZDiTM developer page: “The data are provided free of charge under the CC0 1.0 licence, for use in any context, with no prior notification required.” Keyless GTFS-Realtime; the page says one update a minute, measured at about every 20 seconds. The feed carries no route id, so every vehicle takes the default bus mode. | None required (CC0); credited to ZDiTM Szczecin as a courtesy |
 | **Carris Metropolitana** (api.carrismetropolitana.pt) | Transit layer live vehicles, Lisbon Metropolitan Area, Portugal | Keyless GTFS-Realtime documented in the operator’s public API repository (github.com/carrismetropolitana/api). No licence is stated for the realtime endpoint; the operator’s static GTFS is CC BY 4.0. Included on the same basis as the Metro Transit and OVapi feeds and credited as a courtesy; it can be switched off if Carris objects. Speeds are published in km/h and converted to m/s by the proxy. Route ids are read as the line number per the operator’s `/v2/routes`. | Courtesy credit to Carris Metropolitana |
+| **Prague PID** (api.golemio.cz) | Transit layer live vehicles, Prague and Central Bohemia, Czechia | CC BY (https://pid.cz/o-systemu/opendata/). Stated: “Data, která lze stáhnout přímo zde z webu, jsou stejně jako celý obsah webu opatřena licencí CC-BY” The PID open-data page lists this realtime feed and licenses the data it publishes under CC BY, crediting the author and any changes. The same page says data served from other sources follows that source’s licence; the feed is served by Golemio, the city’s data platform, which states none of its own. Keyless since the catalogue moved it off the X-Access-Token endpoint. Speeds are m/s, checked against movement on 2026-11-07. Route ids are `L` plus the line number; lines below 100 are trams. | Pražská integrovaná doprava (PID) / Golemio |
+| **Warsaw buses and trams** (mkuran.pl) | Transit layer live vehicles, Warsaw, Poland | Warsaw Open Data Project Usage Terms (https://mkuran.pl/gtfs/). Stated: “The City Hall requires a credit by providing the name Miasto Stołeczne Warszawa, data download date (use the timestamp from the FeedHeader) and link to http://api.um.warszawa.pl.” Positions come from the Warsaw City Hall API, repackaged as GTFS-RT by Mikołaj Kuranowski’s unofficial feed. The credit names the city and its API; the download date it asks for is the feed timestamp the layer already shows with each snapshot. Vehicle timestamps ran about two minutes old on 2026-11-07, which the delayed playback absorbs. | Miasto Stołeczne Warszawa (api.um.warszawa.pl) |
+| **Bordeaux TBM** (bdx.mecatran.com) | Transit layer live vehicles, Bordeaux, France | Licence Ouverte / Etalab 2.0 (https://transport.data.gouv.fr/datasets/offres-de-services-bus-tram-et-scolaire-au-format-gtfs-netex-gtfs-rt-siri-lite). The quote is the licence field of the national access point’s dataset record (fr-lo is the Licence Ouverte), which asks only for credit. The `apiKey` in the URL is not a credential: it is the same fixed string printed in the open-data listing for everyone. Speeds are m/s. Trams run on lettered lines A–D; numbered lines are buses. | Bordeaux Métropole (TBM) |
+| **Sendai City Bus** (api-public.odpt.org) | Transit layer live vehicles, Sendai, Japan | CC BY 4.0 (https://creativecommons.org/licenses/by/4.0/). Served by the Open Data Challenge for Public Transportation (ODPT) public API, which needs no key for this feed; the catalogue records CC BY 4.0 as its licence. Vehicle timestamps ran about two minutes old on 2026-11-07. Speeds are m/s. | 仙台市交通局 (Sendai City Transportation Bureau) / ODPT |
+| **Poznań buses and trams** (ztm.poznan.pl) | Transit layer live vehicles, Poznań, Poland | ZTM Poznań open-data terms (https://www.ztm.poznan.pl/otwarte-dane/dla-deweloperow/). Stated: “Treści udostępniane są bezwnioskowo i bezpłatnie, na zasadach powszechnego dostępu i stanowią źródło informacji.” Reuse is free on three conditions: name the source, give the date of the last update, and say the data were processed. The credit names ZTM and says processed; the snapshot timestamp is the update date. The feed carries no bearing, so heading comes from movement between fixes. | Zarząd Transportu Miejskiego w Poznaniu (processed) |
+| **Gdańsk buses and trams** (ckan2.multimediagdansk.pl) | Transit layer live vehicles, Gdańsk, Poland | CC BY 4.0 (https://dane.gov.pl/pl/dataset/38599,rozklady-jazdy-i-lokalizacja-przystankow-gtfs-rt). The national catalogue (dane.gov.pl) lists this dataset under CC BY 4.0. No bearing; heading comes from movement. Speeds are m/s. | Zarząd Transportu Miejskiego w Gdańsku |
+| **Edmonton Transit Service** (gtfs.edmonton.ca) | Transit layer live vehicles, Edmonton, AB | City of Edmonton Open Data Agreement (https://www.edmonton.ca/transportation/Web-version2.1-OpenDataAgreement.pdf). The agreement is the same municipal template as Mississauga and Burlington: a licence to use, modify and distribute for any lawful purpose, in any medium. It was read from search excerpts; the PDF itself would not extract here. Route ids are zero-padded. Speeds are m/s. | Contains information licensed under the Open Data Agreement – City of Edmonton |
+| **Halifax Transit** (gtfs.halifax.ca) | Transit layer live vehicles, Halifax, NS | Halifax Open Data Licence (https://www.halifax.ca/home/open-data/open-data-licence). The catalogue points at Halifax’s open-data licence; the licence page renders only in a browser and was not quoted. Speeds are m/s. | Halifax Regional Municipality (Halifax Transit) |
+| **Victoria Regional Transit** (bct.tmix.se) | Transit layer live vehicles, Victoria, BC | BC Transit Open Data Terms of Use (https://www.bctransit.com/open-data/terms-of-use). Stated: “BC Transit grants you a limited, revocable and non-exclusive license to use, reproduce, and redistribute the Data in accordance with these Terms.” The grant is revocable, like the Ontario municipal templates. Route ids carry a `-VIC` system suffix. Speeds are m/s. | BC Transit |
+| **Montpellier TaM** (gtfsproxy.e-tam.fr) | Transit layer live vehicles, Montpellier, France | ODbL (https://transport.data.gouv.fr/datasets/offre-de-transport-tam-en-temps-reel-gtfs-rt-urbain-et-suburbain). The quote is the dataset record’s licence field. ODbL asks for credit and share-alike on a derived database; the layer redistributes no database, it draws the positions. Speeds are km/h: readings ran 3.3 times the measured movement on 2026-11-07, so the proxy converts them. | Montpellier Méditerranée Métropole (TaM) |
+| **Kraków buses** (gtfs.ztp.krakow.pl) | Transit layer live vehicles, Kraków, Poland | No licence stated (https://gtfs.ztp.krakow.pl/). ZTP publishes this feed keyless on its own GTFS server and lists it in the Mobility Database, but states no licence there or on dane.gov.pl. Shipped on the same basis as Metro Transit and OVapi; switch it off if ZTP objects. | Zarząd Transportu Publicznego w Krakowie |

+| **Rome public transport** (romamobilita.it) | Transit layer live vehicles, Rome, Italy | No licence stated (https://mobilitydatabase.org/feeds/gtfs_rt/mdb-1776). Keyless file on the agency’s own site; the catalogue’s older `/sites/default/files/` path now 404s. No licence found; same basis as Metro Transit and OVapi. Fewer than one vehicle in five carries a bearing, so most headings come from movement. | Roma Servizi per la Mobilità |
+| **Turin GTT** (percorsieorari.gtt.to.it) | Transit layer live vehicles, Turin, Italy | No licence stated (https://mobilitydatabase.org/feeds/gtfs_rt/mdb-2696).

ACTV lists this feed in its own open-data catalogue; that page would not render for a script, so its licence is not quoted. Same basis as Metro Transit and OVapi.

+| **Adelaide Metro** (gtfs.adelaidemetro.com.au) | Transit layer live vehicles, Adelaide, SA | No licence stated for the realtime feed (https://mobilitydatabase.org/feeds/gtfs_rt/mdb-1772). Official keyless endpoint; the state catalogue page refused automated reads, so no licence is quoted. Same basis as Metro Transit and OVapi. Speeds are m/s. The server picks its encoding from Accept, hence the override. | Adelaide Metro |
+| **MARTA buses** (gtfs-rt.itsmarta.com) | Transit layer live vehicles, Atlanta, GA | No licence stated (https://mobilitydatabase.org/feeds/gtfs_rt/mdb-1601). Official keyless endpoint; no licence found. Same basis as Metro Transit and OVapi. Speeds are m/s. | MARTA |
+| **Denver RTD** (open-data.rtd-denver.com) | Transit layer live vehicles, Denver, CO | RTD GTFS-realtime licence agreement (https://www.rtd-denver.com/business-center/open-spatial-data/gtfs-realtime-license-agreement). RTD links a licence agreement for its realtime feeds; the page refused automated reads (403), so it is not quoted. The feed itself is keyless. Speeds are m/s. | Regional Transportation District (RTD) |
+| **Cluj-Napoca CTP** (cluj-rt-feed.gtfs.ro) | Transit layer live vehicles, Cluj-Napoca, Romania | No licence stated (https://mobilitydatabase.org/feeds/gtfs_rt/mdb-2614). Keyless; no licence found. Same basis as Metro Transit and OVapi. | Compania de Transport Public Cluj-Napoca |
+| **Iași CTP** (iasi-rt-feed.gtfs.ro) | Transit layer live vehicles, Iași, Romania | No licence stated (https://mobilitydatabase.org/feeds/gtfs_rt/mdb-2118). Keyless; no licence found. Same basis as Metro Transit and OVapi. | Compania de Transport Public Iași |
+| **Rzeszów city transport** (mpkrzeszow.pl) | Transit layer live vehicles, Rzeszów, Poland | MPK Rzeszów open data (https://www.mpkrzeszow.pl/otwartedane/). Listed on the operator’s open-data page, which names no licence. No bearing; heading comes from movement. | MPK Rzeszów |
+| **Málaga EMT** (gtfs.emtmalaga.es) | Transit layer live vehicles, Málaga, Spain | No licence stated (https://mobilitydatabase.org/feeds/gtfs_rt/mdb-2213). Keyless; no licence found. Same basis as Metro Transit and OVapi. No bearing; heading comes from movement. | EMT Málaga |
+| **Carris (Lisbon city)** (gateway.carris.pt) | Transit layer live vehicles, Lisbon, Portugal | No licence stated (https://mobilitydatabase.org/feeds/gtfs_rt/mdb-2930). Keyless official gateway; no licence found. Same basis as Metro Transit and OVapi. Carries neither bearing nor speed, and vehicle reports run about a minute old. Route ids append a variant. | Carris |
+| **BAS.MY Johor Bahru** (api.data.gov.my) | Transit layer live vehicles, Johor Bahru, Malaysia | No licence stated for the feed (https://mobilitydatabase.org/feeds/gtfs_rt/mdb-3174). Served keyless by Malaysia’s national open-data API; no licence for the feed was found. Same basis as Metro Transit and OVapi. Without the trailing slash the API redirects. Route ids append an operator code. | BAS.MY / data.gov.my |

The metropolis publishes its realtime data under the Licence Ouverte (dataset record quoted); this registry reads it through bus-tracker.fr, an unofficial relay that merges the city’s networks into one GTFS-RT file. Route ids carry the network prefix (`TCAR:`). | Métropole Rouen Normandie (Astuce) / bus-tracker.fr |

 - **Houston TranStar cameras.** Keyless. The camera list is the public `traffic.houstontranstar.org/data/layers/cctvSnapshots_json.js` catalog (~1,000 cameras across Greater Houston); frames are stills at `www.houstontranstar.org/snapshots/cctv/<id>.jpg`, synthesized from a validated numeric id rather than taken from the payload, and only that host is registered. Cameras whose catalog id is `0` (a different, non-snapshot class) and cameras outside Greater Houston are dropped. TranStar's `dir` field is the side of the freeway the camera sits on, not the way it faces: TranStar's own map shows it as "Traffic closest to the camera is traveling …" (South → eastbound, North → westbound, West → southbound, East → northbound). That travel direction (90°, 270°, 180°, 0°) seeds the heading as a low-confidence prior with the low-confidence pose; `None` or an unknown value uses the shared id-hash fallback at low confidence. Headings are corrected with the in-app calibration gizmo. Off by default. TranStar's [Content Usage terms](https://traffic.houstontranstar.org/disclaimer.aspx) prohibit copying or distributing the site's information, and external framing or linking to specific images, without TxDOT's prior written permission; its FAQ grants permission-free use only for the RSS feeds. This project does not hold that permission for downstream installations, so the pack loads only when an operator who holds TxDOT's written permission sets `CCTV_HOUSTON_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to TranStar. Once enabled, it loads the 250 cameras nearest downtown, Uptown, the Medical Center, IAH and Galveston; `CCTV_HOUSTON_MAX_SOURCES` (8–400) changes the cap. Snapshots update about every 3 minutes, which is also the ambient still cadence. Frames are fetched from TranStar and relayed to the browser on demand, buffered only transiently per request, sent with `Cache-Control: no-store`, and not archived.
 - **Autostrada del Brennero (A22) webcams.** Keyless. The camera list is one request to the Open Data Hub tourism API (`tourism.api.opendatahub.com/v1/WebcamInfo?source=a22`), run by NOI Techpark in South Tyrol, which republishes Autobrennero's own list of 13 motorway webcams with coordinates and kilometre markers. Frames are the operator's stills on `www.autobrennero.it/WebCamImg/km<N>.jpg`, refreshed about once a minute, and only the exact image for each camera's kilometre is registered. The feed names no bearing, so headings use the id-hash fallback at low confidence. The road climbs from about 20 m in the Po valley to about 1,370 m at the Brenner Pass, so each camera's ground elevation comes from a per-kilometre table sampled from the Copernicus GLO-90 DEM (via Open-Meteo's elevation API); a camera not in the table uses a 200 m prior. The Open Data Hub tags every record CC0 (`ClosedData: false`, Autobrennero as licence holder), but that tag is the aggregator's metadata and Autobrennero publishes no terms of its own for the images, so they are credited to the operator as a courtesy and are not redistributed. Frames are fetched at request time and never stored. Disable with `CCTV_A22_ENABLED=0`.
 - **Camera frame content.** Public camera frames can contain people, vehicles and license plates, and the camera layer does nothing with them beyond putting them on the map. A successful upstream response is relayed as the provider served it: nothing in the camera pipeline blurs, redacts, enhances or restores it, and nothing there runs face, plate or object detection or otherwise recognises or classifies what is in the picture. (The ALPR layer described below maps where plate-reader cameras are, from locations contributors tagged in OpenStreetMap; it reads nothing from any camera frame.) When an upstream has no frame for a camera, what you see instead is a Google Street View still or the app's own placeholder card; the panel's source badge names which of them you are looking at, and a refresh that fails after a frame has arrived leaves the last good picture on screen rather than replacing it. The browser resamples each frame for display: onto a fixed 1920x1080 surface for the camera's projection plane in the scene, and onto a 192x108 canvas for the small ambient card. That scaling is the only change made to the picture, and the only pixels the camera layer reads back are a 64x36 downscale hashed to tell whether the picture has changed. Live streams are piped through; the still path reads the image into memory to pass it on — TxDOT wraps its JPEG in a JSON envelope, which is decoded there — and no frame is written to disk (the disk cache, `.gev-cache/`, holds feed JSON for other layers and never camera imagery). Outside that pipeline, the voice assistant is the one feature that sends imagery anywhere: when it answers a question about what is in view it may attach a downscaled screenshot of the rendered scene — including any camera plane on screen — to the request it sends to the voice model. Frames are fetched only from server-registered camera URLs — a client cannot hand the proxy a URL (see [SECURITY.md](SECURITY.md)). What the app does stays inside the line README draws: no named-person search, no face recognition, no tracking individuals.
-- **Transit (GTFS-Realtime).** The proxy requests only registered operator feeds, validates redirects, bounds responses, and uses conditional requests, short snapshot caching and failure backoff. All twenty registered feeds, covering nineteen regions, are live-enabled; each can be disabled independently. Vehicles use delayed playback between reports, with report age and waiting states shown separately. Session-local selected trails are available for every feed. MBTA additionally retains up to 15 minutes of recently observed positions in the running proxy, so available history can survive a browser reload; server restart clears it. History reads never fetch upstream, and other feeds have no proxy retention. Nothing is archived to disk or collected in the background. Operator text credits are included as a courtesy and do not imply endorsement. Heights are aligned to work with Google 3D tiles; subway markers are shown at street level because these feeds do not supply depth. The TTC feed is BusTime, the surface system: it carries buses and streetcars and no subway at all. About four in ten of its vehicles report no route at all (unassigned or deadheading), and those are shown with the feed default rather than a route-established mode. It sends no ETag or Last-Modified, so its conditional requests fall through to the ordinary snapshot cache. Three Golden Horseshoe neighbours run alongside it — MiWay, Hamilton HSR and Durham Region Transit — each bus-only and each polled only near its own region. Durham Region Transit publishes no bearing on any vehicle, so those sprites take their heading from observed movement like any other feed that omits it. Guelph, Kingston and Barrie extend the same pattern eastward and north. Hamilton, Guelph, Burlington, YRT and Rio’s SMTR publish route ids that are not the number on the vehicle, so those entries carry a route-name table taken from each operator’s own published GTFS; any id missing from a table renders unchanged rather than blank. A label is never invented: YRT runs a route `9101` that appears nowhere in its published routes, so it stays as the feed sends it. Burlington’s is the one that cannot be shortcut: `351` is route 1 while `3510` is route 10, so the table is a real join rather than a trimmed prefix. GO Transit / Metrolinx is deliberately absent: its REALTIME feed requires an API key issued by manual review, which the keyless admission rule excludes (its static schedule download is keyless, but carries no vehicle positions). Barrie and YRT/Viva each invite acceptance of their licence through a form, and each licence also states that using the data is itself acceptance; this deployment relies on that clause, which is recorded in both entries. Grand River Transit in Waterloo is absent for a different reason: it answers, but its feed header was months stale and it publishes no per-vehicle timestamps, so it would render vehicles that look live and are not. Ottawa’s OC Transpo falls to the same keyless admission rule as GO Transit — its realtime feed requires an API key. London Transit and Thunder Bay Transit publish vehicle positions over plain HTTP with no HTTPS endpoint available. Every other Ontario system — Brampton, Oakville, Niagara, Milton, Windsor, Greater Sudbury, UP Express and a dozen smaller operators — publishes static GTFS schedules only, with no realtime vehicle positions to register. Between the nine included and these exclusions, every Ontario realtime vehicle-position feed catalogued in the Mobility Database is accounted for.

 - **Radio country coverage (optional).** Set `RADIO_PRIORITY_COUNTRIES=IN,PL` in the local `.env` and restart to include stations beyond the global click charts. The operator may choose up to eight unique ISO alpha-2 country codes; no key is needed. Each country adds one bounded query (at most 200 rows) and reserves up to 40 unique, usable stations inside the existing 750-station catalog. Country seeds precede specialist-tag seeds and global popularity fill; unused slots return to the shared pool. This is a coverage preference, not an exhaustive national directory or a guarantee of stations in every city. Countries with no eligible HTTPS MP3/AAC geolocated stations remain empty. An unset list preserves global selection. Country requests share the directory cache and three-worker pool; failed country queries are reported in coverage without blocking a healthy global refresh. Failed/degraded refreshes back off for one minute, with at most three mirrors per query.
 
 - **Radio Browser.** In every installation, including when `RADIO_PRIORITY_COUNTRIES` is unset, each request tries at most three mirror candidates (later fallback candidates are skipped), and failed or partial catalog refreshes back off for 60 seconds. A cold-start failure therefore continues returning 503 during that delay even if upstream recovers. `/api/radio/stations` discovers official API mirrors, makes bounded and coalesced healthy/geolocated HTTPS-station queries, caches the normalized public-domain directory for 45 minutes, and may serve the last good catalog for up to seven days during an outage. Refreshes must meet minimum accepted-query and station coverage before replacing a warm catalog; broad/specialist responses whose rows all fail the product's health policy do not count as successful queries. Optional priority-country outcomes are advisory: valid, in-limit responses with no eligible stations succeed as empty results, while failed or malformed country queries report unsuccessful coverage without degrading the global catalog. A usable partial cold catalog is explicitly `DEGRADED`, and non-array or empty broad/specialist payloads are rejected atomically. Individual structurally malformed rows are skipped rather than failing the whole query; the response carries their bounded `rejectedStationCount` (at most 10,000), which the client adds to its own rejected rows and reports as degraded coverage without discarding the accepted generation. Every directory and click-count request rejects redirects, validates all resolved addresses as globally routable (including reserved/documentation IPv4 and special/non-global IPv6 exclusions), and pins the TLS connection to a validated address. Only MP3/AAC non-HLS directory rows with public HTTPS stream targets are returned; favicons are intentionally omitted. Pressing play connects one browser audio element directly to the selected broadcaster and calls the directory's click counter through known-ID-only `POST /api/radio/click/:uuid`. GEV never proxies, caches, records, bundles, or redistributes audio. Radio Browser supplies station-level tags, not dependable current-song or upcoming-program metadata, so Radio filtering never claims either. Direct playback exposes the listener's IP address to the broadcaster, whose own stream terms apply.

-- Add Szczecin, Poland and the Lisbon Metropolitan Area to the Transit layer.
-  Szczecin's buses and trams come from ZDiTM's keyless feed under CC0 1.0; it
-  carries no route ids, so vehicles show as buses. Lisbon's buses come from
-  Carris Metropolitana's keyless feed, which states no licence of its own and

+  read as the line on the vehicle; Prague, Bordeaux and Le Havre trams and

Subject: [PATCH 047/113] feat(satellites): owner, operator and COSPAR
 groundwork for the orbital view

The orbital view reads a satellite's owner country, operator, COSPAR id,
TLE epoch and whether its class can be ridden. #1558 now carries only
what the class toggles read, so this brings the rest back here, where it
is first used: the classes.js helpers and the UCS pack's operator and
owner fields.

 - **Satellite classes** (`src/layers/satellites/classes.js`): every satellite is filed under one of six classes, each with its own point colour, legend swatch and toggle: STATIONS (warm white), IMAGING (cyan), TELECOM (violet; communications and navigation, so GPS, GLONASS, Galileo and BeiDou read as one family), STARLINK (dim slate), PROBES (muted blue-gray) and DEBRIS (receding brown-gray). That module is the single source of truth for class, label and colour, so the dot, the card and the legend swatch cannot disagree. Two deliberate palette rules: no class may sit in the 40–48° amber band, which is the app-wide known-military convention; and STARLINK stays far below PROBES in Rec.601 luminance so the dense shell stays separable when NVG/FLIR collapse the scene to one channel. The ISS keeps its long-standing red hero dot rather than the STATIONS colour — it carries a permanent name label and its card still reads `STATIONS · ISS`; it is a station whichever group ingested it, so a stations-feed outage cannot refile it. `src/data/satelliteClass.js` keeps the group-based labels beneath the classes: the constellation subtype and a group's own label for a satellite with no class.
 - Class is also a **text field**, not just a color: `TELECOM · GPS` / `STARLINK` / `STATIONS · ISS` leads the tracked card's detail block and replaces the raw CelesTrak tag on the detection-overlay label. Because that canvas composites above the post-FX chain, the class stays readable in NVG/FLIR after the in-scene dot colors are flattened.
 - The satellites row in DATA LAYERS carries per-layer sub-controls (`DataLayerManager._syncRowControls`, the first consumer of the optional `getRowControls()` layer hook): one chip per class (the STARLINK chip exposes the existing `catalog` param), a swatch legend with live per-class counts, and an info line while SATCAT is stale or unavailable (`Classes may lag: SATCAT is a cached copy` / `Classes may lag: SATCAT unavailable`). Default is the sparse core catalog. The chips are stateless — each declares the params to apply and the manager owns the write — so the Space Missions capture/restore path over the same param stays authoritative. Controls stay hidden while the layer is off. An explicit CORE or DENSE choice participates in versioned local and share-link state; temporary Space Missions overrides do not.
-- **Class toggles** (`src/layers/satellites/classes.js`): the layer row carries one chip per class — STATIONS, IMAGING, TELECOM (communications and navigation), PROBES (science, technology development and demonstration, unknown purpose) and DEBRIS (rocket bodies, fragments, unknown objects launched before last year and dead payloads) on by default, so the layer shows what it did before classes; STARLINK off, as DENSE was. Points of a hidden class stay built and are only hidden, so a toggle needs no reload; hidden classes are left out of the detection overlay, the voice/framing position lists and analyst answers (the tracked satellite still answers), and the legend keys only the classes on screen. The class comes, strongest evidence first, from CelesTrak SATCAT (object type and operational status, fetched per group through `/api/celestrak-satcat/<group>`, cached a day by the proxy; the layer keeps a current read six hours rather than asking on every five-minute update), the bundled UCS Satellite Database pack (UCS-Satellite-Database 5-1-2023: each satellite's purpose; `src/data/local_data/ucs_satellites/`), name patterns for satellites launched after May 2023, and finally the CelesTrak groups the TLE came in (a mission group such as `weather` before the orbit group `geo`; a UCS purpose of "Unknown" counts as none). Only crewed stations and the craft that visit them, by name, are STATIONS: the CubeSats CelesTrak's stations group also carries after their deployment from the ISS are classed like any other satellite. A payload whose SATCAT record gives no status, with no UCS record and no recognisable name, that launched 20 or more years ago (SATCAT's launch date, else the TLE designator's year) is presumed dead and filed as debris; without a SATCAT record (a failed read) nothing is presumed. To cover imaging launched after the UCS snapshot the core catalog also reads CelesTrak's `resource`, `weather`, `planet`, `sar` and `science` groups. Retired stations and the shuttles have re-entered and have no orbit to show. An explicit class choice is kept in local and share-link state as the `classes` option, one letter per class shown (`sitpd`: stations, imaging, telecom, probes, debris; `0`: none; `src/data/satelliteClassMask.js`), and the layer takes those letters back through `setParams({classes})`; STARLINK maps to the existing `catalog: 'dense'` param instead.

 - **The STARLINK chip (formerly DENSE) reports the dense LOAD, not the catalog param.** The param flips synchronously while the Starlink shell takes seconds to arrive over a chunked load, and CelesTrak 502s that feed regularly. So the chip reads `STARLINK ···` (busy, disabled) while loading, ACTIVE only once dense points are actually on screen, and `STARLINK ✕` with the reason on hover when the load fails — a failure also reverts `catalog` to `core`, drops any partial chunk, and leaves the chip clickable to retry. A load is judged by points added, not by HTTP status: a 200 carrying an empty body, a passed-through HTML error page, or only TLEs the core catalog already owns fails with the same revert semantics as a 502. Any explicit request for `core` clears a latched error even when the mode does not change, so a Space Missions restore of an already-core snapshot never leaves the user with a failure they did not cause. Because the load settles asynchronously, the layer pushes a re-render through the optional `setRowControlsListener()` hook; nothing else would repaint that row before the 5-minute catalog refresh, so the count and legend would otherwise sit stale.
 - **A dependency owner takes the row with it.** Space Missions borrows this layer for TLE lookup with `showPoints:false`; while points are hidden the layer returns empty row controls, so the legend never describes an empty sky and the chip cannot accept a write that the owner's restore would silently revert.
 - The detection-overlay record cache (`_detectionObjects`) is cleared with the catalog on every rebuild: it stamps id/class at creation only, and a rebuild can re-tag a satellite when a partial CelesTrak outage changes which group wins dedupe.

Subject: [PATCH 048/113] feat(cockpit): ride a tracked satellite in an orbital
 view
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

With a satellite tracked and no aircraft tracked, Cockpit can ride the
satellite. Entry needs only the Satellites layer; debris can be tracked but
not entered, and voice stays aircraft-only. Double-clicking the tracked
satellite or the entry buttons (reading ORBIT) enter it.

The camera sits on the satellite's per-frame SGP4 position and looks
straight down, turned to the ground track (north-up for a satellite with
none). The optical zoom steps 1x to 8x with a focus pull, the arrows tilt
the view up to 45 degrees off nadir, and Home or 0 returns to nadir. Off
nadir the tilt reads its total angle first and the swath readout becomes an
approximation marked with ≈. While in orbit the map leases flat Esri
imagery, the cloud pass stays off and the view opens in the optical style.

The orbital HUD names the satellite with its owner's flag (from the
flag-icons package, loaded per country) or an organisation badge, its
operator, class, NORAD and COSPAR ids and TLE epoch with the element lines
on request, altitude, orbital speed and the sub-satellite point. CURRENTLY
OVER names the country and its first-level division, or the sea, and from
8x the most prominent populated place nearby, looked up offline from the
bundled Natural Earth packs (populated places are a new pack). The
satellites layer hides the ridden satellite's own marks, dims the other
orbit rings and ignores scene clicks and Escape while held. Exit restores
the camera's field of view and the satellite's follow camera.

C no longer enters or leaves Cockpit, bridge or orbit: it is left to the
app-wide CCTV shortcut, and Escape or the exit button leave first person.

+### Orbital view
+
+With a satellite tracked and no aircraft tracked, Cockpit can ride the
+satellite instead. Entry needs only the Satellites layer
+(`orbitEntryAllowed` in `src/contextModePolicy.js`); Contacts and every other
+layer may be off. A Context mode change in flight blocks entry until it
+settles. Debris (rocket bodies, fragments and dead satellites; see the
+satellite class toggles) can be tracked but never entered: no ORBIT entry is
+offered and double-click refuses it. A tracked aircraft still takes
+entry first, and a tracked satellite
+takes it before a selected vessel. Double-clicking the tracked satellite
+enters it, and the entry button reads
+ORBIT with a satellite icon in Contacts (`#cockpit-entry`) and under the Intel
+HUD readout (`#cockpit-entry-readout`). Voice (`control_cockpit`) stays
+aircraft-only; its state reports an orbital view in use as a `satellite`
+subject. `gev:cockpit-mode-changed` carries layer `satellites` and the NORAD
+id.
+
+The camera sits on the satellite's own per-frame SGP4 position
+(`getCockpitPosition`, the sample the dot uses) and looks at the Earth's
+centre track-up: the ground track points to the top of the frame, so the
+picture scrolls along it (`nadirOrientation` in `src/cockpitOrbital.js`). A
+satellite with no ground track (a geostationary one) is shown north-up, and
+over a pole the previous frame's up is kept. It updates on every rendered
+frame, with no ground clamp. Entry opens in the plain optical vision style
+(the other styles stay one click away) and leases the map for flat imagery:
+with Google 3D tiles shown, which stay coarse from hundreds of kilometres up,
+the map switches to Esri imagery, and exit puts it back unless the operator
+picked another map meanwhile; another owner already holding the map (an
+imagery comparison) keeps it as it is. The Cockpit cloud pass is off in orbit
+(it fades out above 24 km); cloud cover from orbit is the Weather layer's,
+and the saved cloud preference stands for the next aircraft or bridge. The layer hides the satellite's dot, docked
+companions, its own orbit ring and its detection bracket, and draws every
+other orbit ring (the ISS ring included) at 30% of its alpha; other
+satellites' points and labels stay. Scene clicks and the layer's Escape are
+ignored while it is ridden. The optical zoom steps 1×, 2×, 4× and 8× with `+`
+(or `=`) and `-` (or `_`) and the panel's buttons: the 1× frame is 60°
+vertical in low orbit and fits the Earth's disk with margin from high orbits,
+each step divides the tangent of the half-angle, and Cesium's `frustum.fov`
+is set from it for the canvas aspect. A step animates over 400 ms with a
+focus-pull blur and a reticle lock tick, and cuts at once under
+`prefers-reduced-motion`. The arrows tilt the view off nadir in 5° steps
+along the frame's axes (Up/Down tilt forward/aft along the ground track,
+Left/Right across it, each axis to ±45°; Shift takes no larger step); Home,
+`0` or NADIR return to nadir. While tilted the panel shows the total angle

 - **Satellite classes** (`src/layers/satellites/classes.js`): every satellite is filed under one of six classes, each with its own point colour, legend swatch and toggle: STATIONS (warm white), IMAGING (cyan), TELECOM (violet; communications and navigation, so GPS, GLONASS, Galileo and BeiDou read as one family), STARLINK (dim slate), PROBES (muted blue-gray) and DEBRIS (receding brown-gray). That module is the single source of truth for class, label and colour, so the dot, the card and the legend swatch cannot disagree. Two deliberate palette rules: no class may sit in the 40–48° amber band, which is the app-wide known-military convention; and STARLINK stays far below PROBES in Rec.601 luminance so the dense shell stays separable when NVG/FLIR collapse the scene to one channel. The ISS keeps its long-standing red hero dot rather than the STATIONS colour — it carries a permanent name label and its card still reads `STATIONS · ISS`; it is a station whichever group ingested it, so a stations-feed outage cannot refile it. `src/data/satelliteClass.js` keeps the group-based labels beneath the classes: the constellation subtype and a group's own label for a satellite with no class.
 - Class is also a **text field**, not just a color: `TELECOM · GPS` / `STARLINK` / `STATIONS · ISS` leads the tracked card's detail block and replaces the raw CelesTrak tag on the detection-overlay label. Because that canvas composites above the post-FX chain, the class stays readable in NVG/FLIR after the in-scene dot colors are flattened.
 - The satellites row in DATA LAYERS carries per-layer sub-controls (`DataLayerManager._syncRowControls`, the first consumer of the optional `getRowControls()` layer hook): one chip per class (the STARLINK chip exposes the existing `catalog` param), a swatch legend with live per-class counts, and an info line while SATCAT is stale or unavailable (`Classes may lag: SATCAT is a cached copy` / `Classes may lag: SATCAT unavailable`). Default is the sparse core catalog. The chips are stateless — each declares the params to apply and the manager owns the write — so the Space Missions capture/restore path over the same param stays authoritative. Controls stay hidden while the layer is off. An explicit CORE or DENSE choice participates in versioned local and share-link state; temporary Space Missions overrides do not.
-- **Class toggles** (`src/layers/satellites/classes.js`): the layer row carries one chip per class — STATIONS, IMAGING, TELECOM (communications and navigation), PROBES (science, technology development and demonstration, unknown purpose) and DEBRIS (rocket bodies, fragments, unknown objects launched before last year and dead payloads) on by default, so the layer shows what it did before classes; STARLINK off, as DENSE was. Points of a hidden class stay built and are only hidden, so a toggle needs no reload; hidden classes are left out of the detection overlay, the voice/framing position lists and analyst answers (the tracked satellite still answers), and the legend keys only the classes on screen. The class comes, strongest evidence first, from CelesTrak SATCAT (object type and operational status, fetched per group through `/api/celestrak-satcat/<group>`, cached a day by the proxy; the layer keeps a current read six hours rather than asking on every five-minute update), the bundled UCS Satellite Database pack (UCS-Satellite-Database 5-1-2023: operator, owner country and purpose; `src/data/local_data/ucs_satellites/`), name patterns for satellites launched after May 2023, and finally the CelesTrak groups the TLE came in (a mission group such as `weather` before the orbit group `geo`; a UCS purpose of "Unknown" counts as none). Only crewed stations and the craft that visit them, by name, are STATIONS: the CubeSats CelesTrak's stations group also carries after their deployment from the ISS are classed like any other satellite. A payload whose SATCAT record gives no status, with no UCS record and no recognisable name, that launched 20 or more years ago (SATCAT's launch date, else the TLE designator's year) is presumed dead and filed as debris; without a SATCAT record (a failed read) nothing is presumed. To cover imaging launched after the UCS snapshot the core catalog also reads CelesTrak's `resource`, `weather`, `planet`, `sar` and `science` groups. Retired stations and the shuttles have re-entered and have no orbit to show. An explicit class choice is kept in local and share-link state as the `classes` option, one letter per class shown (`sitpd`: stations, imaging, telecom, probes, debris; `0`: none; `src/data/satelliteClassMask.js`), and the layer takes those letters back through `setParams({classes})`; STARLINK maps to the existing `catalog: 'dense'` param instead.

To cover imaging launched after the UCS snapshot the core catalog also reads CelesTrak's `resource`, `weather`, `planet`, `sar` and `science` groups. Debris can be tracked but is never ridden: the orbital entry gate (`orbitEntryAllowed`) refuses it, so no ORBIT entry is offered and double-click does nothing for it. Retired stations and the shuttles have re-entered and have no orbit to show. An explicit class choice is kept in local and share-link state as the `classes` option, one letter per class shown (`sitpd`: stations, imaging, telecom, probes, debris; `0`: none; `src/data/satelliteClassMask.js`), and the layer takes those letters back through `setParams({classes})`; STARLINK maps to the existing `catalog: 'dense'` param instead.
+- The satellite Cockpit subject (`getCockpitSubject()`) also carries `satelliteClass`, `cosparId` (from SATCAT, else TLE line 1), `tle` (`{line1, line2, epochMs}`), `owner` (`{countryCode, label}`: ISO 3166-1 alpha-2 for a single country, `null` code for organisations such as ESA, EUMETSAT or Intelsat and for joint owners) and `operator` (UCS; SpaceX for Starlink). UCS names the operator's country and wins over the SATCAT owner code; CelesTrak's CIS (former USSR) is filed under Russia.
 - **The STARLINK chip (formerly DENSE) reports the dense LOAD, not the catalog param.** The param flips synchronously while the Starlink shell takes seconds to arrive over a chunked load, and CelesTrak 502s that feed regularly. So the chip reads `STARLINK ···` (busy, disabled) while loading, ACTIVE only once dense points are actually on screen, and `STARLINK ✕` with the reason on hover when the load fails — a failure also reverts `catalog` to `core`, drops any partial chunk, and leaves the chip clickable to retry. A load is judged by points added, not by HTTP status: a 200 carrying an empty body, a passed-through HTML error page, or only TLEs the core catalog already owns fails with the same revert semantics as a 502. Any explicit request for `core` clears a latched error even when the mode does not change, so a Space Missions restore of an already-core snapshot never leaves the user with a failure they did not cause. Because the load settles asynchronously, the layer pushes a re-render through the optional `setRowControlsListener()` hook; nothing else would repaint that row before the 5-minute catalog refresh, so the count and legend would otherwise sit stale.
 - **A dependency owner takes the row with it.** Space Missions borrows this layer for TLE lookup with `showPoints:false`; while points are hidden the layer returns empty row controls, so the legend never describes an empty sky and the chip cannot accept a write that the owner's restore would silently revert.
 - The detection-overlay record cache (`_detectionObjects`) is cleared with the catalog on every rebuild: it stamps id/class at creation only, and a rebuild can re-tag a satellite when a partial CelesTrak outage changes which group wins dedupe.

-- **Aircraft cockpit view:** selecting a commercial or military aircraft reveals a `COCKPIT` action (`C`) once that aircraft's own layer is on; Contacts is not required. The action shows in Contacts (`#cockpit-entry`) and under the Intel HUD's bottom-right readout (`#cockpit-entry-readout`, with the HUD on, in its Tactical and Cyber layouts), so entry needs no Contacts panel. Turning off the ridden aircraft's layer ends the view (the layer clears its tracking). When an air feed the surrounding picture uses is off, the Cockpit says so instead of blocking: Live Signals leads with `MILITARY FEED OFF · PARTIAL PICTURE` or `FLIGHTS FEED OFF · PARTIAL PICTURE`, and the Contact card shows that line in place of its inputs status, so a partial picture is never presented as complete. `control_cockpit` refuses entry with `entryBlockedReason` `contacts-starting` (a Context change in flight), `subject-layer-off` (the aircraft's layer, or with none tracked any aircraft layer, is off) or `no-tracked-aircraft`. Cockpit mode temporarily releases Cesium's orbit-follow transform and drives a first-person camera from the tracked aircraft's existing smoothed display position and course. Its concave helmet-visor HUD shows callsign, UTC time, coordinates, curved roll/pitch guides, and a seven-division heading tape. Ambient commercial and military AIR contacts use a Cockpit near/far band selected by the shared Display 3D mode: Proximity admits at 150 km and retains to 185 km; All admits at 400 km and retains to 450 km. The shared 3D toggle now applies in Cockpit: Off keeps in-range contacts as rotating 2D aircraft silhouettes, while On lets a ready admitted glTF take over without a drawing gap. The Cockpit model cap remains 60 and can only lower the map budget; in-range contacts that are capped or still loading remain 2D silhouettes instead of degrading to out-of-range dots. Contacts outside the selected band use small rotation-free cyan-white pips for civilian aircraft and amber pips for military. The pilot's own airframe is not drawn in first person, and exiting clears the Cockpit band and restores normal map silhouettes/models. The normal left accordion remains available for Layers and Authoring and keeps the same 26vh HUD-aligned anchor used in map mode, independent of whether the bottom-left Contact card is expanded or collapsed; the right-rail CCTV and Context chooser are hidden to avoid duplicating or overlapping the cockpit presentation. When the intelligence HUD is enabled, its classification, scene summary, collection/orbit metadata, coordinates, and imaging-status text remain visible as reduced peripheral cockpit telemetry; the optical center and flight instruments stay clear, and turning the HUD off still hides it. Ground speed, exact heading, and rendered altitude form one compact lower-center instrument cluster, keeping the horizon and peripheral view open. A second live altitude tape hugs the inside-right visor rim: its rail and nine moving ticks are derived from the same responsive keyhole radius, remain 20 px inside the circular edge even on wide displays, fade deeply at both vertical ends, and move continuously behind a fixed current-altitude pointer; its interval tightens automatically near the surface and it is suppressed on narrow screens. Cockpit mode also has a weather-backed transparent volumetric-cloud pass derived from the supplied FBM/domain-warped R&D shader. It renders at no more than 520×320, uses 24 ray steps/three FBM octaves at 12 FPS, is clipped to the visor, fails clear when Open-Meteo is unavailable, and stops its animation completely on cockpit exit. It does not restore the prior CPU weather canvases, precipitation, scene fog, or any map-mode effect. When Contacts is active for the tracked aircraft, the compact `CONTACT` rail adds the 250 km subject window, four cohort counts, nearest observed/mapped example with relative bearing and distance, freshness, explicit uncertainty, and Previous and Next controls plus its own collapse control. The mirrored right rail is a three-page **cockpit briefing carousel**: source-backed live signals, location-matched regional headlines, and physical-region/current-weather context from bundled Natural Earth polygons and Open-Meteo. It is manual-first: Previous, Next, and direct page controls are always available, and the visible `CYCLE OFF` / `CYCLE ON` control starts or stops the nine-second page cycle. The cycle pauses on hover or keyboard focus and stops while collapsed, hidden, or outside cockpit mode; live signal data continues refreshing either way. Empty news matches and unavailable news use compact text states rather than reserving an empty media frame; partial local data remains explicit. Article links open their original publisher, and no headline is treated as verified risk intelligence. On desktop both cockpit rails use the same width and share a bottom-aligned safe baseline in opposite corners above the peripheral MGRS/GSD/time telemetry, leaving both that text and the lower-center instrument cluster readable. They collapse independently to slim tabs without stopping live data updates. Narrow screens use separated top/bottom fallbacks. Empty-space globe clicks are inert while cockpit owns the camera; `C`, `Escape`, or `EXIT COCKPIT` explicitly exits and restores the same tracked entity and standard follow camera. Unknown feeds remain unknown, selection loss still exits safely without inventing a replacement track, and the cockpit never presents the summary as threat scoring or an all-clear.

 - **Cockpit left-panel clearance:** the Cockpit Contact card and peripheral HUD participate in the adaptive left accordion's live obstacle measurements, including live viewport-height changes. Expanding Layers or Authoring keeps the active panel in the available upper-left corridor with internal scrolling; it does not cover the Contact card, lower Cockpit controls, or Cesium credit line. Outside Cockpit the hidden card does not alter the normal corridor.
 - **Cockpit Context scope:** the 250 km radius applies to the air/sea proximity cohorts. Installation counts come only from the currently loaded viewport and are labeled `CURRENT VIEWPORT ONLY` in the cockpit as well as the normal Context panel; neither surface presents them as a complete 250 km installation survey.
 - **Cockpit camera anchor:** first-person mode does not write feed-boundary corrections directly into the camera. A cockpit-only inertial anchor advances from the selected aircraft's displayed course and speed, then converges toward the authoritative delayed track with correction capped below forward motion. The displayed kinematics are derived from the same consecutive fix segment as the rendered position, with raw feed speed/course used only as fallback; a transient zero/missing feed speed therefore cannot freeze a visibly moving aircraft after layer enable or a map/cockpit handoff. Rendered altitude continues to come from that interpolated track position. Late ADS-B fixes and short render stalls can remove drift without accelerating or reversing the view. Camera placement runs before scene update/culling at a bounded 20 Hz so a moving cockpit does not force Photoreal 3D Tiles to retraverse on every display frame; textual instruments update at 10 Hz and context/layout work at 4 Hz. Every far Cockpit contact pip shares one stable Cesium texture-atlas entry and skips unused screen-projected course calculations, while only in-range 2D aircraft silhouettes pay the screen-projected rotation cost; ambient glTF collections are hidden/retained rather than synchronously destroyed at cockpit entry, and context rails lay out only on explicit content/state changes and viewport resize. The deliberate 15/30-second layer interpolation delays and per-Cesium-frame position caches remain unchanged.
-- **Cockpit route, vision, and view controls:** visible on-screen `COCKPIT`, `RESET`, and `EXIT COCKPIT` controls replace reliance on the `C` shortcut. RESET uses the same canonical globe route as the map and voice actions, exits Cockpit, and releases its camera ownership rather than exposing the hidden map-style top action. When the tracked commercial flight has a plausible ADSBDB route, the top of the right briefing rail shows a compact `FROM → TO` airport strip and the visor shows a centered estimated-destination chevron with its relative bearing; its destination label rounds to whole degrees in 000–359, wrapping rounded north to 000° while the chevron continues to use the relative bearing independently of label rounding; absent or implausible route data hides the strip and cue rather than guessing. The cockpit-local vision control is an interactive `PREV / CURRENT / NEXT` carousel over `NORMAL`, `CRT`, `NVG`, `FLIR`, `ANIME`, and `NOIR`; its previous/next actions wrap, and activating the current value advances to the next style. Cockpit enters on the active map preset, so a Cyber FLIR map opens Cockpit on FLIR while Normal remains a distinct option instead of producing a second FLIR entry. Cockpit choices temporarily activate the existing Cesium post-process stages, while exiting Cockpit through either EXIT or RESET restores the pre-entry map style. The regional-news page uses a free Google News RSS locality query first, with the existing GDELT query retained only as a fail-soft fallback; linked headlines remain reporting, not verified incidents or risk intelligence.
+- **Cockpit route, vision, and view controls:** visible on-screen `COCKPIT`, `RESET`, and `EXIT COCKPIT` controls are the way in and out; Cockpit claims no `C` shortcut, so `C` keeps toggling CCTV, also inside a first-person view.

 - Cockpit wind-direction labels wrap after rounding to whole degrees, so a direction of 359.5° displays as `N · 0°` rather than `N · 360°`.
 - The transit, ALPR, vessel, CCTV, Local ADS-B, flight and military context, awareness, Cockpit and Street Level heading readouts round through `roundHeadingDegrees` in `src/data/headingDegrees.js` (whole degrees 0–359, `null` when not finite, so each caller keeps its own placeholder); `normalizeHeading` lives there too and `cockpitMath.js` re-exports it. The Cockpit's `TRACK ACQUIRED` signal uses `formatHeadingReadout`, so a 359.6° track reads `COURSE 000°`.
 - **Cockpit missing observations:** missing local weather observations remain unknown rather than being converted to zero or clear skies, in the briefing and in the cloud effects; a missing temperature drops the whole local weather record, including its wind and condition.

Subject: [PATCH 050/113] feat(cockpit): zoom the orbital view to the imaging
 sensor's swath

An imaging satellite with a known sensor can now zoom past 8x, up to 128x,
as far as the view stays at least as wide as the sensor's narrowest
standard swath at its live altitude; only swaths confirmed on a cited page
open those steps. The top step follows the altitude and window shape and
steps back when it falls below the zoom shown.

The view draws the sensor's swath to scale along the ground track with a
SENSOR SWATH readout (approximate off nadir), and a SENSOR button zooms to
exactly that width when it lies in range at nadir. From 16x the imagery
tiles the view will need 5 to 20 s ahead along the ground track are
pre-loaded at the matching level. The mouse wheel steps the zoom one notch
at a time, and the identity line shows how old the TLE is. The sensor
figures come from a new bundled pack of 46 Earth-observation platforms,
each value cited to its operator or agency, with its own data credit.

 Operator, owner country and purpose for active satellites, keyed by NORAD number, from the Union of Concerned Scientists Satellite Database release **UCS-Satellite-Database 5-1-2023** (data current through 2023-05-01; https://www.ucsusa.org/satellite_database). The satellites layer joins it to CelesTrak positions and SATCAT records to file each satellite as a station, imaging, telecom, Starlink, probe or debris object, and to name its operator and owner. Section 3 of the UCS database manual: "The Database is free and its use is unrestricted. We request that its use be acknowledged and referenced in written materials. References should include the version of the Database that was used, which is indicated by the name of the Excel file, and a link to or URL for the webpage www.ucsusa.org/satellite_database." The app acknowledges it in the Data attribution popover. UCS has paused updates since this release; Starlink rows are dropped (Starlink is classed by name).

+Swath widths and ground resolutions for 46 Earth-observation platforms (Landsat, Sentinel, MODIS, VIIRS, GOES, Himawari, Gaofen, CBERS, RADARSAT, TerraSAR-X, COSMO-SkyMed, ALOS, KOMPSAT, SPOT, Pléiades, WorldView, SkySat, PlanetScope, ICEYE, Capella, Umbra and others), compiled 2026-11-04 from the operator and agency pages cited per entry. The orbital view draws each satellite's sensor swath to scale and caps its zoom at that swath. Facts only; no text or images copied. A swath is confirmed on an operator, agency (ESA's eoPortal included) or academic page; resellers are not cited. The CEOS MIM Database (CC BY 4.0) is not yet used.

+lets it zoom past 8x only as far as that swath (`src/layers/satellites/sensors.js`,
+`src/data/imagingSensors.js`, `orbitalMaxZoom` in `src/cockpitOrbital.js`).
+
+| File | Content | Entries |
+|------|---------|---------|
+| `imaging_sensors.json` | Platform, match rule, operator, instruments, altitude, imaging modes (swath km, best ground resolution m), narrowest standard swath, sources, unverified fields | 46 |
+
+**Compiled:** 2026-11-04, by hand from the pages cited per entry (`sources`).
+Each match pattern was checked against CelesTrak's active list that day.
+Altitude is the nominal value from a cited source; where none was found it is
+the median altitude of the matching satellites from CelesTrak GP data, noted in
+`unverified`. The app zooms on the live altitude, not this one.
+
+**Narrowest standard swath** is the narrowest continuous standard imaging swath
+or scene width (cross-track); for a geostationary imager, the narrower side of
+its smallest standard scan area. Some listed modes are left out of it:
+
+- Sampling modes: SAR wave vignettes, and Himawari's Landmark Area scans
+  (1000 × 500 km), so Himawari's narrowest is the 1000 km Target Area.
+- Generations the operator has retired: PlanetScope's Dove Classic and Dove-R
+  (about 25 km scenes, imagery until April 2022 per Planet) stay in `modes`,
+  while its narrowest is the SuperDove's 32.5 km. The `^FLOCK ` name rule
+  would also match those older Doves.
+
+**Unverified values.** A value not confirmed on an opened page is named in the
+entry's `unverified` list. `swathConfirmed` is false when the narrowest swath is
+missing or unverified; such a platform keeps the base 1–8x zoom steps:
+
+- Landsat 9 (swath inferred from Landsat 8), ResourceSat-2 (LISS-3 swath),
+  SuperView Neo-1 (12 km from search snippets only), BlackSky and Meteosat
+  MTG FCI (no swath found).
+
+## Sources and licences
+
+The values are individual specification facts, each cited from the
+operator's or agency's official pages listed per entry in `sources`. No text or
+images are copied. The main sources:
+
+- **Operator and agency pages and spec sheets** (NASA, USGS, NOAA/NESDIS,
+  ESA SentiWiki and Earth Online, EUMETSAT, JAXA, ISRO/NRSC, INPE, CSA, DLR,
+  JMA, ASI, KARI, China's Ministry of Natural Resources (LASAC), Planet,
+  Vantor (formerly Maxar) datasheet pages, L3Harris, China Siwei, BlackSky,
+  Airbus and KOMPSAT-5 via the Disasters Charter, ICEYE, Capella, Umbra,
+  Satellogic, Chang Guang).
+- **Academic papers and proceedings** (Sensors papers on Gaofen-3, KARI's
+  ACRS 2012 paper on KOMPSAT-3, CAST's IAC-16 abstract on Gaofen-2).
+- **eoPortal** (ESA's mission directory, an institutional source): a swath
+  read there counts as confirmed. It is cited beside the operator's and
+  agency's pages, and alone for values they do not give (the wider modes of
+  Gaofen-3 and COSMO-SkyMed Second Generation, and a few other entries).
+  Gaofen-1 takes eoPortal's 69 km PMS and 830 km WFV swaths by maintainer
+  choice; a 2019 Chinese lecture and a Sensors paper give 60 and 800 km.
+- **CEOS MIM Database** (https://database.eohandbook.com): CC BY 4.0 since
+  7 September 2026, with the credit "CEOS MIM Database,
+  https://database.eohandbook.com". No entry relies on it yet; credit it if
+  values are taken from it later.

Subject: [PATCH 051/113] docs(cockpit): describe the orbital view's
 sensor-aware zoom

The Orbital view section said the zoom stops at 8x. It now covers the
16x to 128x steps for satellites with a confirmed sensor swath, capped
from live altitude, the mouse wheel, the SENSOR button, the to-scale
swath strip and readout (approximate off nadir), the imagery pre-load
ahead of the ground track, the TLE age on the identifier line, and that
the sensor values cite operator and agency pages per platform.

+the satellite's live altitude and the window's shape is still at least as
+wide as that swath (`orbitalMaxZoom` in `src/cockpitOrbital.js`); when the
+cap falls below the zoom shown, the view steps back to it. Unconfirmed
+swaths add no steps. The sensor's swath is drawn to scale as a strip along
+the ground track with a SENSOR SWATH readout, and a SENSOR button zooms
+to exactly that width when it lies between 1× and the cap. Tilted off nadir
+the strip stays (view and swath widen alike), the readout scales as the swath
+readout does (`SENSOR SWATH ≈ 191 KM`), and SENSOR, a nadir framing, is
+hidden. A swath is confirmed only on the operator's, an agency's (ESA's
+eoPortal included) or an academic page for its platform. From
+16×, with flat imagery on the globe (not Google 3D tiles) and the view at
+nadir, every 2 s the view asks the base imagery layer for the tiles it will
+need 5 to 20 s ahead along the ground track (`prefetchImageryAhead` in
+`src/ui/cockpitOrbitalView.js`), so the browser has them cached when the
+view arrives. The level is the one Cesium will draw there
+(`imageryLevelForView` in `src/cockpitOrbital.js`, following Cesium's own
+choice: the terrain level whose error spans at most the globe's maximum
+screen-space error, then the imagery level whose texels are nearest that
+error, about one to two screen pixels per texel). It asks for at most 12
+tiles at a time through Cesium's request scheduler, throttled per server and
+at the lowest priority, so a request is declined while the imagery server's
+slots are taken by the tiles on screen and is the first dropped when the
+scheduler is full (a declined tile is asked for again later); it remembers the last 512 tiles asked for and does not ask
+for those again. While tilted off nadir the view looks away from the track,
+so nothing is pre-loaded. The arrows tilt the view off nadir in 5° steps
 along the frame's axes (Up/Down tilt forward/aft along the ground track,

Subject: [PATCH 063/113] fix(cockpit): the pre-load serves every lead's centre

 sensor waits for the eased view to reach the Earth

ground point of a layer that is on, such as a Mapped Installations site, a
fire or a local data pack feature) keeps the camera on it. Each frame the
look is aimed from the satellite's position to the point's Earth-fixed
position in the track-up nadir frame the arrows tilt, so the point stays
at the centre as the satellite moves. The swing onto the point, or between
points, uses the arrows' easing on a slower clock and then holds the point
exactly; reduced motion cuts.

A click elsewhere, FOCUS on the focused point, NADIR, Home or 0 ends the
focus and the view eases back to nadir; an arrow ends it and tilts on from
where the view is. The focus also ends, easing back, when the point leaves
the ±45° reach or the satellite's horizon, when its layer is turned off or
its record is dropped, and with the view. While focused the readout gives
the single off-nadir angle to the point (OFF-NADIR 23.4°), names it in a
polite live region, and the swath reads approximate as for a tilt. Clicks
still reach Cesium's own handler and never untrack the satellite; a click
a tool owns is ignored.

Under the readout, IN REACH lists the mapped points facing the satellite
that are within the reach or in the frame, nearest to nadir first and at
most 12, rebuilt once a second. A row opens the point's position, source
and OpenStreetMap tags (or its layer's properties); FOCUS focuses it,
switches to it, or ends the focus held on it, and is unavailable for a
point in frame but beyond the reach.

Subject: [PATCH 066/113] fix(cockpit): keep the orbital view on a double-click
 at a ground point

In the orbital view a double-click on a mapped ground point went on to
Cesium's own double-click, which tracks the picked entity and so ended the
view. The Cockpit's double-click routing now takes it in orbit: it keeps or
starts the focus on that point (a point beyond the reach is left unfocused
but still not tracked). A double-click anywhere else, one a tool owns, and
every one outside orbit go on to Cesium's as before, and stopping the
Cockpit still hands Cesium's handler back.

Subject: [PATCH 069/113] feat(cockpit): list orbit's sites and satellites in
 Live Signals

The orbital Context card is gone and the Contact card stays hidden in orbit
again. Live Signals page 1 had nothing in orbit but TRACK ACQUIRED, because
orbit feeds no Contacts snapshot; it now lists what is around the
satellite, built the way the aircraft rows are, five rows with stable keys
rebuilt once a second. Rows already shown keep their places while they
still qualify, so a site passing under a low orbit is not pulled from under
the pointer.

Site rows come from the Mapped Installations layer (getNearby, asked only
as far as the reach extends) and focus their site, or release it on the
focused site's row, which reads as the subject does. A site the layer drops
during its frequent reloads stays listed for 10 s, since sites do not move.
With the layer off nothing is listed and a SITES STANDBY row says why.
Satellite rows come from the satellites layer's bounded nearest query,
measured from the satellite itself, and ride the satellite; RETURN goes
back to the one before, skipping one that has left the catalogue. While
the camera hops to a new satellite only TRACK ACQUIRED and RETURN show, so
nothing is measured from the old position. An arrow pressed while a focus
eases back takes the arrows' own clock. Site and satellite rows name their
own actions.

+In orbit the briefing's Live Signals page (OBSERVED / MAPPED PINGS) lists
+what is around the satellite, as the aircraft Cockpit lists the contacts
+of its Contacts snapshot (`src/ui/cockpitOrbitalSignals.js`): five rows at
+most, rebuilt once a second with stable keys, so a row keeps its place and
+time. TRACK ACQUIRED stays first. Then:
+
+- **Sites**: the Mapped Installations layer's loaded records around the
+  sub-satellite point (`getNearby`, asked only as far as the reach extends
+  over the ground) that face the satellite and lie within the off-nadir
+  reach, nearest to nadir first, the focused site always among them. A row
+  reads the site's name over its class and off-nadir angle; its button
+  (`Keep the camera on …`) focuses the site, and on the focused site's row,
+  marked as the subject is (`FOCUS · …`, `Release the camera from …`), ends
+  the focus. With Mapped Installations off the layer keeps its records, so
+  nothing is listed then: a SITES STANDBY row says to turn the layer on.
+- **Satellites**: the nearest shown satellites to the ridden one, debris
+  left out (the satellites layer's bounded `getNearestPositions`, measured
+  from the satellite itself), with their bearing from the top of the frame
+  and distance. A row (`Ride …`) rides that satellite. While there is a
+  satellite ridden before this one, a RETURN · *name* row goes back to it; if
+  that satellite has left the catalogue it is dropped and RETURN offers the
+  one before. Riding stays in orbit: the satellites layer tracks the new
+  satellite (`trackById`), the Cockpit takes the camera back at once and
+  marks it as the ridden subject, any ground focus ends with the view easing
+  back to nadir, and the camera hops to the new satellite along the great
+  circle over 1.2 s (cut under reduced motion), keeping the zoom. Until the
+  camera is on the new satellite the page shows only TRACK ACQUIRED and
+  RETURN, then rebuilds at once.
+
+Sites take two rows while satellites fill the rest, more when there are
+fewer satellites. The Contact card stays hidden in orbit.
+
+The focus (`src/ui/cockpitOrbitalFocus.js`, geometry in
+`src/cockpitOrbitalFocus.js`) aims the look each frame from the satellite's
+position to the site's Earth-fixed position in the same track-up nadir
+frame the arrows tilt, so the site stays at the centre as the satellite
+moves. The turn onto it (and between sites) eases what is left of the swing
+with the arrows' easing on a slower clock (250 ms time constant, about
+0.75 s to 95%), then holds the site exactly, and cuts under

+the pick is resolved through the layer's own pick ids (`findByPick`: a named
+marker's `{ installationId }` or a site entity). A click anywhere else, the
+focused site's row, NADIR, Home or `0` ends the focus and the view eases
+back to nadir on the same clock; an arrow ends it (or the ease back) and
+tilts on from where the view is. The layer reloads its thinned view as the
+camera moves (about once a second in orbit), so a site in view can leave
+its records for a moment: while the layer is on, a site seen in the last
+10 s stays a candidate (sites do not move), so the rows hold still and a
+row's site can be focused, and a focused site keeps its last position. The focus ends by
+itself, easing back, when the site leaves the reach (either tilt axis past
+±45°, or the site below the satellite's horizon), when the layer is turned
+off, when another satellite is ridden, and with the orbital view. A site
+beyond the reach cannot be focused. While focused the readout gives the
+single off-nadir angle to the site, as image metadata does

Subject: [PATCH 074/113] Draw rows take an application's own actions

createApplicationTools({ drawMarkActions }) adds an application's buttons to
the rows of drawn areas and lines. An action gets the shape's id, kind, name,
row title and [lon, lat] geometry, and what it returns or resolves to is a
note under the row. The standalone shell passes none, so the open-source
build is unchanged.

 - UTILITIES ▸ **Draw** turns the globe into a whiteboard drawn by hand. Pick a shape (icon buttons for Area, Line and Pin) and a colour swatch for the next shape, click the vertices on the real world, and finish. **Keyboard contract, live only while Draw is on and never while you are typing in another field:** Enter finishes the shape (as does a double-click, and the two cannot both submit it — the session is replaced before the annotate call is awaited); Backspace removes the last vertex; Esc cancels the shape in progress, and a second Esc — Esc on an empty session — leaves draw mode. **Clear** wipes the board (the shape in progress and every placed mark), so removing marks does not require the console or the microphone.
 - **Drawn shapes are listed under Draw like Import's files** (`src/ui/views/panels/DrawMarkList.vue`, rows worded by `presentDrawMarks` in `src/annotations/drawMarks.js`): one row per hand-drawn mark (`manual: true`; voice marks are not listed) with its colour swatch, its name, and show/hide, fly-to and remove. The draw tool publishes the rows with the rest of its controls and answers the row actions (`renameDrawMark`, `recolorDrawMark`, `toggleDrawMark`, `flyToDrawMark`, `removeDrawMark`) through the display store; it republishes on the engine's `onChange`, so a voice clear or an expiry updates the list. Rows are keyed and updated in place: a board change never takes a name being typed (the field keeps its draft while focused) or the button under a click. The name is saved on Enter or on leaving the field, once; Esc restores it, before anything else and with the row's colours open too. Both keep focus in the field, so neither drops it to the page or leaves Draw. The swatch opens the five colours right after it (shown at the end of the row), with the current colour focused; the arrows, Home and End try another, and a click or Esc closes them and returns focus to the swatch. Both colour groups (the next shape's and a row's) are one `DrawSwatches` radio group with a single tab stop, coloured from `DRAW_COLOR_CSS`; on touch screens each dot answers a 24 px target. An unnamed shape shows its kind, and an unnamed line its length; a renamed line keeps its length (`Ridge walk — 950 m`). **Hidden** keeps a mark on the board at alpha 0, and the world renderer takes every one of its entities out (`show = false`), so no material that keeps its own colour (the line's flowing stroke) still paints it; the screen renderer does not project a hidden callout, so it cannot push a visible label aside; `fly_route` skips a hidden route; and with every mark hidden the annotations render hold is released. **Fly to** is an immediate navigation (`runImmediateNavigation('drawing', …)`), like Import's: Cockpit refuses it and a running orbit, follow or track lets go first. A line is framed by its whole path, across the antimeridian too.
-- Runtime entry: `createApplicationTools` (`src/app/tools.js`, behind the `src/standalone/tools.js` shim) calls `initDrawTool({ viewer, annotations, navigation, publish, connect })` after `initAnnotations` and defers its `destroy()`, so disposing the shell returns every DOM listener, the Cesium handler, the preview data source, the borrowed click actions and the `window.__gevDrawTool` handle. Its controls are Vue views in the UTILITIES panel (`DrawControls.vue`, `DrawMarkList.vue`) that render what the tool publishes to the display store and call its actions. That handle (`setActive`, `setShape`, `addVertex(lon, lat)`, `finish`, `cancel`, `clearAll`, `marks`, `setColor`, `diagnostics`) is the no-mouse test seam.

+- **Row actions are an application's own.** `createApplicationTools({ drawMarkActions })` hands `initDrawTool` buttons for drawn areas' and lines' rows; the standalone shell passes none, so the open-source build shows no new button and makes no new request. Each action (`drawMarkActions` in `src/annotations/drawMarks.js`) is `{ id, icon, label(name), shapes: ['area', 'line'], accepts?(geometry, shape), run({ id, shape, name, title, geometry }) }`: the icon a Material Symbols name, the label worded by the application, `name` the person's own and `title` the row's (the name, else `Area` or `Line · 950 m`), the geometry `drawMarkGeometry`'s `[lon, lat]` `Polygon` (closed; a `MultiPolygon` for an area handle with several parts) or `LineString`, longitudes wrapped into [-180, 180]. A pin, and a shape that crosses the antimeridian or has a part that cannot be given whole, has no geometry and is offered nothing. Malformed actions and repeated ids are dropped once, at construction. What `run` returns or resolves to is a note under the row (`role=status`; past 200 characters it is cut at a word with an ellipsis); the row is busy (`aria-disabled`, no second press) until it settles, a rejection or a throw clears the note and is logged (so an action words its own refusals and resolves with them), and a shape's note goes with the shape, so a late answer never lands on a removed one.
 - Contract: a finished shape is submitted through the SAME `annotationEngine.annotate()` the voice agent uses, with geometry supplied and `manual: true` (`type: area` + `ring`, `type: route` + `path`, `type: pin` + coordinates). `resolveSpec` short-circuits manual specs (`resolveManualSpec`) so no geocoder, Places or Overpass call is made. A drawn area is a real (not synthesized) outline and drapes solid; a drawn line is a `route` with `mode: 'manual'`, labelled with its length and never a travel time; a pin is a point. Drawn marks therefore render with the whiteboard look, persist, appear in `.list()`, and clear with `clear_annotations` / `.clear()`. A drawn shape is never merged with another as a duplicate: every one is drawn on purpose, and every one is unnamed until its row names it, so two pins dropped close together are two pins.
 - **A vertex is a lon/lat, and the mark is DRAPED.** Clicks are picked through `pickWorldFromScreen` — one of two scene helpers the annotation resolver factory (`src/annotations/resolver.js`) exposes alongside `sampleGroundHeight`, so the app has ONE depth-aware pick cascade rather than a second written beside it — which returns the height the pick landed on as well as the coordinate, so the live preview hangs on the roof or hillside under the pointer instead of sinking to sea level. The world renderer draws areas and routes with `clampToGround`, so the height is dropped at finish in one place (`finishSpec`) rather than being carried downstream and discarded silently: what you get is the outline you drew, lying on the surface beneath it.
 - **Draped marks classify onto `ClassificationType.BOTH`** — terrain AND 3D tiles — not onto 3D tiles alone. With only `CESIUM_3D_TILE`, every area fill, area outline, route and arrow rendered to nothing on a keyless boot, where Cesium's own globe carries Esri/OSM imagery and there are no tiles to classify against; the labels appeared and the geometry did not. That hit spoken annotations exactly as hard as hand-drawn ones. `scripts/qa-draw-tool.mjs` counts the mark's own colour in the rendered frame before and after a shape is finished, on a keyed AND a keyless server, so "the board says there is a mark" can no longer pass for "the mark is on screen".

+# Owner flags
+
+`owner_flags.png` is one sheet of every owner country a satellite can be
+marked with (`OWNER_COUNTRY_CODES` in `src/layers/satellites/classes.js`),
+drawn at 40 × 30 px (twice the orbital readout's 20 × 15) in sorted code
+order, 16 to a row. `src/ui/ownerFlag.js` loads it once at startup and draws
+each flag from its cell; the layout is `src/ui/ownerFlagSheet.js`.
+
+**Source:** the 4:3 SVGs of [flag-icons](https://github.com/lipis/flag-icons)
+7.5.0 (a devDependency, used only to build the sheet).
+
+**License:** flag-icons is MIT licensed (© Panayiotis Lipiridis). Country
+flags themselves are not copyrightable designs in most jurisdictions.
+
+**Regenerate:** `node scripts/build-owner-flags.mjs` (after adding an owner
+country, or updating flag-icons). With the same flag-icons and sharp versions
+a rerun reproduces both files byte for byte.

 the loading batch failed; flags keep their neighbours out from under the
 border and out of a scaled flag's edge; a new ride asks again for a sheet
 that failed

Subject: [PATCH 084/113] fix(voice): send OpenAI Realtime tool schemas the API
 accepts
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

OpenAI Realtime now answers 400 invalid_function_parameters for a whole
session whose tool schema uses Unicode property classes, as resolve_area's
area-id pattern does, so voice never connects ("Failed to create Realtime
token"). The session sends its tools through chatSchema, the filter typed
chat adopted in #1616, which leaves out only \p{…} patterns; area ids are
still checked against the action's own contract before the tool runs.

Fixes #1618

 | **SMTR Rio de Janeiro** (dados.mobilidade.rio) | Transit layer live vehicles, Rio de Janeiro: municipal buses (SPPO) and the Mobi-Rio BRT, as two feeds | CC BY 4.0, stated on both data.rio catalog pages. Keyless GTFS-Realtime published by the Secretaria Municipal de Transportes, labelled beta, with a gateway limit of 5 requests a second and 60 a minute. Line names come from SMTR’s GTFS `routes.txt` (dados.mobilidade.rio/gtfs/schedule), under the same licence. | Attribution to SMTR / Prefeitura da Cidade do Rio de Janeiro under CC BY 4.0 |
 | **ZDiTM Szczecin** (zditm.szczecin.pl) | Transit layer live vehicles, Szczecin, Poland: buses and trams as one feed | CC0 1.0, stated on the ZDiTM developer page: “The data are provided free of charge under the CC0 1.0 licence, for use in any context, with no prior notification required.” Keyless GTFS-Realtime; the page says one update a minute, measured at about every 20 seconds. The feed carries no route id, so every vehicle takes the default bus mode. | None required (CC0); credited to ZDiTM Szczecin as a courtesy |
 | **Carris Metropolitana** (api.carrismetropolitana.pt) | Transit layer live vehicles, Lisbon Metropolitan Area, Portugal | Keyless GTFS-Realtime documented in the operator’s public API repository (github.com/carrismetropolitana/api). No licence is stated for the realtime endpoint; the operator’s static GTFS is CC BY 4.0. Included on the same basis as the Metro Transit and OVapi feeds and credited as a courtesy; it can be switched off if Carris objects. Speeds are published in km/h and converted to m/s by the proxy. Route ids are read as the line number per the operator’s `/v2/routes`. | Courtesy credit to Carris Metropolitana |
-| **Prague PID** (api.golemio.cz) | Transit layer live vehicles, Prague and Central Bohemia, Czechia | CC BY (https://pid.cz/o-systemu/opendata/). Stated: “Data, která lze stáhnout přímo zde z webu, jsou stejně jako celý obsah webu opatřena licencí CC-BY” The PID open-data page lists this realtime feed and licenses the data it publishes under CC BY, crediting the author and any changes. The same page says data served from other sources follows that source’s licence; the feed is served by Golemio, the city’s data platform, which states none of its own. Keyless since the catalogue moved it off the X-Access-Token endpoint. Speeds are m/s, checked against movement on 2026-11-07. Route ids are `L` plus the line number; lines below 100 are trams. | Pražská integrovaná doprava (PID) / Golemio |

Stated: “The City Hall requires a credit by providing the name Miasto Stołeczne Warszawa, data download date (use the timestamp from the FeedHeader) and link to http://api.um.warszawa.pl.” Positions come from the Warsaw City Hall API, repackaged as GTFS-RT by Mikołaj Kuranowski’s unofficial feed. The credit names the city and its API; the download date it asks for is the feed timestamp the layer already shows with each snapshot. Vehicle timestamps ran about two minutes old on 2026-11-07, which the delayed playback absorbs. | Miasto Stołeczne Warszawa (api.um.warszawa.pl) |

The quote is the licence field of the national access point’s dataset record (fr-lo is the Licence Ouverte), which asks only for credit. The `apiKey` in the URL is not a credential: it is the same fixed string printed in the open-data listing for everyone. Speeds are m/s. Trams run on lettered lines A–D; numbered lines are buses. | Bordeaux Métropole (TBM) |

Subject: [PATCH 089/113] fix(transit): read Rouen and Le Havre from the
 operators' own feeds
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Rouen now reads Métropole Rouen Normandie's TCAR vehicle feed
(api.mrn.cityway.fr) and Le Havre LiA's own GTFS-RT
(opendata.transports-lia.fr), both listed in their transport.data.gouv.fr
records, instead of the unofficial bus-tracker.fr relay. LiA ids carry an
8- prefix, so a new liaRouteLabel strips it and liaRouteMode reads the line.

- "destination refresh" is the refresh at the place the camera flew to,
  so restore "son actualisation à destination".
- Radio note: "que vous la demandez par la voix", "Votre adresse IP".
- "{count} / 30D": "30 J", like "{days} j".
- Starlink: "la couche complète", as in the active-state tooltip.
- "Show {name} sighting": colon form, so names starting with a vowel
  do not break the elision after "de".
- Wildlife note: Acartia is the source, not a kind of marine mammal.
- Straight apostrophes in the five strings added on main since.

A malformed record answers 400 and a failed write 500, both with a fixed message.

Subject: [PATCH 096/113] feat(draw): hand one drawn area or line back to the
 application

createApplicationTools returns drawShape({ shape, signal }): it opens Draw
for one area or line and resolves with its Polygon or LineString without
placing a mark, or null when draw mode is left, the signal aborts, a newer
request replaces it, the pointer is held elsewhere or the tool goes. The
shape controls cannot change the asked-for shape, and a shape across the
antimeridian is refused as a row's actions refuse it and drawn again. It
also returns pointerFree, so an application's own click handlers yield to a
tool holding the pointer, as the layers' do.

 - UTILITIES ▸ **Draw** turns the globe into a whiteboard drawn by hand. Pick a shape (icon buttons for Area, Line and Pin) and a colour swatch for the next shape, click the vertices on the real world, and finish. **Keyboard contract, live only while Draw is on and never while you are typing in another field:** Enter finishes the shape (as does a double-click, and the two cannot both submit it — the session is replaced before the annotate call is awaited); Backspace removes the last vertex; Esc cancels the shape in progress, and a second Esc — Esc on an empty session — leaves draw mode. **Clear** wipes the board (the shape in progress and every placed mark), so removing marks does not require the console or the microphone.
 - **Drawn shapes are listed under Draw like Import's files** (`src/ui/views/panels/DrawMarkList.vue`, rows worded by `presentDrawMarks` in `src/annotations/drawMarks.js`): one row per hand-drawn mark (`manual: true`; voice marks are not listed) with its colour swatch, its name, and show/hide, fly-to and remove. The draw tool publishes the rows with the rest of its controls and answers the row actions (`renameDrawMark`, `recolorDrawMark`, `toggleDrawMark`, `flyToDrawMark`, `removeDrawMark`) through the display store; it republishes on the engine's `onChange`, so a voice clear or an expiry updates the list. Rows are keyed and updated in place: a board change never takes a name being typed (the field keeps its draft while focused) or the button under a click. The name is saved on Enter or on leaving the field, once; Esc restores it, before anything else and with the row's colours open too. Both keep focus in the field, so neither drops it to the page or leaves Draw. The swatch opens the five colours right after it (shown at the end of the row), with the current colour focused; the arrows, Home and End try another, and a click or Esc closes them and returns focus to the swatch. Both colour groups (the next shape's and a row's) are one `DrawSwatches` radio group with a single tab stop, coloured from `DRAW_COLOR_CSS`; on touch screens each dot answers a 24 px target. An unnamed shape shows its kind, and an unnamed line its length; a renamed line keeps its length (`Ridge walk — 950 m`). **Hidden** keeps a mark on the board at alpha 0, and the world renderer takes every one of its entities out (`show = false`), so no material that keeps its own colour (the line's flowing stroke) still paints it; the screen renderer does not project a hidden callout, so it cannot push a visible label aside; `fly_route` skips a hidden route; and with every mark hidden the annotations render hold is released. **Fly to** is an immediate navigation (`runImmediateNavigation('drawing', …)`), like Import's: Cockpit refuses it and a running orbit, follow or track lets go first. A line is framed by its whole path, across the antimeridian too.
 - Runtime entry: `createApplicationTools` (`src/app/tools.js`, behind the `src/standalone/tools.js` shim) calls `initDrawTool({ viewer, annotations, navigation, publish, connect, markActions })` after `initAnnotations` and defers its `destroy()`, so disposing the shell returns every DOM listener, the Cesium handler, the preview data source, the borrowed click actions and the `window.__gevDrawTool` handle. Its controls are Vue views in the UTILITIES panel (`DrawControls.vue`, `DrawMarkList.vue`) that render what the tool publishes to the display store and call its actions. That handle (`setActive`, `setShape`, `addVertex(lon, lat)`, `finish`, `cancel`, `clearAll`, `marks`, `setColor`, `diagnostics`) is the no-mouse test seam.
+- **One shape, handed back.** `createApplicationTools` also returns `drawShape({ shape, signal })` (`drawTool.drawShape`): it opens draw mode for one `area` or `line` and resolves with its geometry, a closed `[lon, lat]` `Polygon` or a `LineString`, without placing a mark; the shape chosen before comes back and draw mode ends. While it is open the controls cannot change the shape, and one across the antimeridian is refused as a row's actions refuse it ("That shape could not be placed.") and drawn again. It resolves `null` when the drawing is cancelled (the second Escape), draw mode is left, `signal` aborts, another request replaces it, the pointer is held elsewhere, the tool is destroyed, or the page has no Draw controls. It returns `pointerFree` (`data/inputOwnership.js` `isPointerFree`) too, so an application's own click handlers yield to the tool holding the pointer, as the layers' do.
 - **Row actions are an application's own.** `createApplicationTools({ drawMarkActions })` hands `initDrawTool` buttons for drawn areas' and lines' rows; the standalone shell passes none, so the open-source build shows no new button and makes no new request. Each action (`drawMarkActions` in `src/annotations/drawMarks.js`) is `{ id, icon, label(name), shapes: ['area', 'line'], accepts?(geometry, shape), run({ id, shape, name, title, geometry }) }`: the icon a Material Symbols name, the label worded by the application, `name` the person's own and `title` the row's (the name, else `Area` or `Line · 950 m`), the geometry `drawMarkGeometry`'s `[lon, lat]` `Polygon` (closed; a `MultiPolygon` for an area handle with several parts) or `LineString`, longitudes wrapped into [-180, 180]. A pin, and a shape that crosses the antimeridian or has a part that cannot be given whole, has no geometry and is offered nothing. Malformed actions and repeated ids are dropped once, at construction. What `run` returns or resolves to is a note under the row (`role=status`; past 200 characters it is cut at a word with an ellipsis); the row is busy (`aria-disabled`, no second press) until it settles, a rejection or a throw clears the note and is logged (so an action words its own refusals and resolves with them), and a shape's note goes with the shape, so a late answer never lands on a removed one.
 - Contract: a finished shape is submitted through the SAME `annotationEngine.annotate()` the voice agent uses, with geometry supplied and `manual: true` (`type: area` + `ring`, `type: route` + `path`, `type: pin` + coordinates). `resolveSpec` short-circuits manual specs (`resolveManualSpec`) so no geocoder, Places or Overpass call is made. A drawn area is a real (not synthesized) outline and drapes solid; a drawn line is a `route` with `mode: 'manual'`, labelled with its length and never a travel time; a pin is a point. Drawn marks therefore render with the whiteboard look, persist, appear in `.list()`, and clear with `clear_annotations` / `.clear()`. A drawn shape is never merged with another as a duplicate: every one is drawn on purpose, and every one is unnamed until its row names it, so two pins dropped close together are two pins.
 - **A vertex is a lon/lat, and the mark is DRAPED.** Clicks are picked through `pickWorldFromScreen` — one of two scene helpers the annotation resolver factory (`src/annotations/resolver.js`) exposes alongside `sampleGroundHeight`, so the app has ONE depth-aware pick cascade rather than a second written beside it — which returns the height the pick landed on as well as the coordinate, so the live preview hangs on the roof or hillside under the pointer instead of sinking to sea level. The world renderer draws areas and routes with `clampToGround`, so the height is dropped at finish in one place (`finishSpec`) rather than being carried downstream and discarded silently: what you get is the outline you drew, lying on the surface beneath it.

Subject: [PATCH 101/113] Keep vehicles off rooftops and bridge decks: probe
 the mesh where the vehicle is

On the photoreal stack the rendered-mesh floor took one probe at each coarse
cell's centre (0.001 degrees) and kept it for the session. A centre on a roof
passed the +80 m DEM window and lifted every vehicle in the cell to roof height
(a Haymarket bus drew 23.5 m above the street, on the garage roof); a centre in
the river put Red Line trains on the Longfellow Bridge 6-9 m under the deck.

The sampler now probes at the caller's point. A cell with a reading is probed
again only at spots about 17 m apart from earlier ones, eight at most, and a
spot refused only because the cell's DEM prior was cold is tried again later.
The floor keeps each reading that passes the gate at the point it was taken
(two within about 5 m keep the lower; sixteen at most per cell) and answers a
read from the reading nearest the asked point, so a viaduct and the street
beside it in one cell keep their own heights.

+## Rendered-mesh floor readings — November 9, 2026
+
+On the photoreal stack the shared floor (`cachedGroundFloor`) answers from
+rendered-mesh readings per coarse cell (0.001°, about 110 × 80 m), sampled by
+`src/services/meshFloorSampler.js` and gated against the DEM by
+`reportValidatedMeshFloorCell` in `src/services/groundFloor.js`. The probe goes
+where the caller's point is (a vehicle or contact), not to the cell's centre;
+the sampler reads a cell at up to eight spots about 12–17 m or more apart, and
+each reading that passes the gate is kept at its point (ground snaps add theirs
+the same way; a cell keeps at most sixteen). A read answers from the cell's
+reading nearest the asked point, so a viaduct and the street beside it in one
+cell keep their own heights; two readings within about 5 m of each other keep
+the lower. A spot refused only because the cell's DEM prior was cold is tried
+again later. Before this, one probe at the cell's centre latched for the
+session, so a centre on a roof lifted everything in the cell (a Haymarket bus
+drew 23.5 m above the street, on the garage roof) and a centre in the river put
+Red Line trains on the Longfellow Bridge 6–9 m under the deck. Residual: the
+probe is vertical, so a vehicle directly under a deck or a roof overhang reads
+the structure above it, and a vehicle between readings takes the nearest one, so
+its floor steps where the nearest reading changes.

Subject: [PATCH 102/113] Read the mesh floor where transit vehicles and
 grounded flights actually are

With readings kept per point, the floor a vehicle gets depends on which point
is probed and where it is read. Transit offered the sampler the first point of
each vehicle's path in a cell, usually its oldest fix there, so a vehicle that
stayed in one cell never had its current spot probed. It now offers the latest
point of the path in each cell, and the newest fix in the vehicle's own cell
(the selected vehicle's history is walked newest first).

The grounded-flight display clamp read the floor at its sticky cell's centre,
which now answers from the reading nearest the centre, not the contact. It
reads at the contact's own position, held inside the sticky cell so boundary
hysteresis still applies.

Subject: [PATCH 104/113] feat(pointer): an application's own tool can take the
 pointer

createApplicationTools returns pointer: claim(owner) takes the pointer as
Draw does and returns its lease, or null while another tool holds it;
release(lease) gives it back; isFree() lets the application's own click
handlers yield, as the layers' do. This replaces drawShape, which this
branch added: Draw is as it was.

 - UTILITIES ▸ **Draw** turns the globe into a whiteboard drawn by hand. Pick a shape (icon buttons for Area, Line and Pin) and a colour swatch for the next shape, click the vertices on the real world, and finish. **Keyboard contract, live only while Draw is on and never while you are typing in another field:** Enter finishes the shape (as does a double-click, and the two cannot both submit it — the session is replaced before the annotate call is awaited); Backspace removes the last vertex; Esc cancels the shape in progress, and a second Esc — Esc on an empty session — leaves draw mode. **Clear** wipes the board (the shape in progress and every placed mark), so removing marks does not require the console or the microphone.
 - **Drawn shapes are listed under Draw like Import's files** (`src/ui/views/panels/DrawMarkList.vue`, rows worded by `presentDrawMarks` in `src/annotations/drawMarks.js`): one row per hand-drawn mark (`manual: true`; voice marks are not listed) with its colour swatch, its name, and show/hide, fly-to and remove. The draw tool publishes the rows with the rest of its controls and answers the row actions (`renameDrawMark`, `recolorDrawMark`, `toggleDrawMark`, `flyToDrawMark`, `removeDrawMark`) through the display store; it republishes on the engine's `onChange`, so a voice clear or an expiry updates the list. Rows are keyed and updated in place: a board change never takes a name being typed (the field keeps its draft while focused) or the button under a click. The name is saved on Enter or on leaving the field, once; Esc restores it, before anything else and with the row's colours open too. Both keep focus in the field, so neither drops it to the page or leaves Draw. The swatch opens the five colours right after it (shown at the end of the row), with the current colour focused; the arrows, Home and End try another, and a click or Esc closes them and returns focus to the swatch. Both colour groups (the next shape's and a row's) are one `DrawSwatches` radio group with a single tab stop, coloured from `DRAW_COLOR_CSS`; on touch screens each dot answers a 24 px target. An unnamed shape shows its kind, and an unnamed line its length; a renamed line keeps its length (`Ridge walk — 950 m`). **Hidden** keeps a mark on the board at alpha 0, and the world renderer takes every one of its entities out (`show = false`), so no material that keeps its own colour (the line's flowing stroke) still paints it; the screen renderer does not project a hidden callout, so it cannot push a visible label aside; `fly_route` skips a hidden route; and with every mark hidden the annotations render hold is released. **Fly to** is an immediate navigation (`runImmediateNavigation('drawing', …)`), like Import's: Cockpit refuses it and a running orbit, follow or track lets go first. A line is framed by its whole path, across the antimeridian too.
 - Runtime entry: `createApplicationTools` (`src/app/tools.js`, behind the `src/standalone/tools.js` shim) calls `initDrawTool({ viewer, annotations, navigation, publish, connect, markActions })` after `initAnnotations` and defers its `destroy()`, so disposing the shell returns every DOM listener, the Cesium handler, the preview data source, the borrowed click actions and the `window.__gevDrawTool` handle. Its controls are Vue views in the UTILITIES panel (`DrawControls.vue`, `DrawMarkList.vue`) that render what the tool publishes to the display store and call its actions. That handle (`setActive`, `setShape`, `addVertex(lon, lat)`, `finish`, `cancel`, `clearAll`, `marks`, `setColor`, `diagnostics`) is the no-mouse test seam.
-- **One shape, handed back.** `createApplicationTools` also returns `drawShape({ shape, signal })` (`drawTool.drawShape`): it opens draw mode for one `area` or `line` and resolves with its geometry, a closed `[lon, lat]` `Polygon` or a `LineString`, without placing a mark; the shape chosen before comes back and draw mode ends. While it is open the controls cannot change the shape, and one across the antimeridian is refused as a row's actions refuse it ("That shape could not be placed.") and drawn again. It resolves `null` when the drawing is cancelled (the second Escape), draw mode is left, `signal` aborts, another request replaces it, the pointer is held elsewhere, the tool is destroyed, or the page has no Draw controls. It returns `pointerFree` (`data/inputOwnership.js` `isPointerFree`) too, so an application's own click handlers yield to the tool holding the pointer, as the layers' do.
+- **The pointer, for an application's own tool.** `createApplicationTools` also returns `pointer` (`data/inputOwnership.js`): `claim(owner)` takes the pointer as Draw does and returns its lease, or `null` while another tool holds it; `release(lease)` gives it back; `isFree()` lets the application's own click handlers yield, as the layers' do. An owner without a name in `pointerOwnerNames.js` is named by its id when another tool reports who holds the pointer.
 - **Row actions are an application's own.** `createApplicationTools({ drawMarkActions })` hands `initDrawTool` buttons for drawn areas' and lines' rows; the standalone shell passes none, so the open-source build shows no new button and makes no new request. Each action (`drawMarkActions` in `src/annotations/drawMarks.js`) is `{ id, icon, label(name), shapes: ['area', 'line'], accepts?(geometry, shape), run({ id, shape, name, title, geometry }) }`: the icon a Material Symbols name, the label worded by the application, `name` the person's own and `title` the row's (the name, else `Area` or `Line · 950 m`), the geometry `drawMarkGeometry`'s `[lon, lat]` `Polygon` (closed; a `MultiPolygon` for an area handle with several parts) or `LineString`, longitudes wrapped into [-180, 180]. A pin, and a shape that crosses the antimeridian or has a part that cannot be given whole, has no geometry and is offered nothing. Malformed actions and repeated ids are dropped once, at construction. What `run` returns or resolves to is a note under the row (`role=status`; past 200 characters it is cut at a word with an ellipsis); the row is busy (`aria-disabled`, no second press) until it settles, a rejection or a throw clears the note and is logged (so an action words its own refusals and resolves with them), and a shape's note goes with the shape, so a late answer never lands on a removed one.
 - Contract: a finished shape is submitted through the SAME `annotationEngine.annotate()` the voice agent uses, with geometry supplied and `manual: true` (`type: area` + `ring`, `type: route` + `path`, `type: pin` + coordinates). `resolveSpec` short-circuits manual specs (`resolveManualSpec`) so no geocoder, Places or Overpass call is made. A drawn area is a real (not synthesized) outline and drapes solid; a drawn line is a `route` with `mode: 'manual'`, labelled with its length and never a travel time; a pin is a point. Drawn marks therefore render with the whiteboard look, persist, appear in `.list()`, and clear with `clear_annotations` / `.clear()`. A drawn shape is never merged with another as a duplicate: every one is drawn on purpose, and every one is unnamed until its row names it, so two pins dropped close together are two pins.
 - **A vertex is a lon/lat, and the mark is DRAPED.** Clicks are picked through `pickWorldFromScreen` — one of two scene helpers the annotation resolver factory (`src/annotations/resolver.js`) exposes alongside `sampleGroundHeight`, so the app has ONE depth-aware pick cascade rather than a second written beside it — which returns the height the pick landed on as well as the coordinate, so the live preview hangs on the roof or hillside under the pointer instead of sinking to sea level. The world renderer draws areas and routes with `clampToGround`, so the height is dropped at finish in one place (`finishSpec`) rather than being carried downstream and discarded silently: what you get is the outline you drew, lying on the surface beneath it.

Subject: [PATCH 105/113] perf(traffic): build road lines one set at a time

With Lines on, every progressive paint of a loading city rebuilt all road
lines: up to three ground-line primitives for as many as 1,500 roads, built
asynchronously. Builds started faster than they finished, and each kept the
set it replaced in the scene until it was ready, so sets piled up.

One set now builds at a time. A rebuild asked for while lines are building
replaces the one waiting, and the newest starts when the build finishes.
Lines replaced by a finished build are removed before the next one starts.
Turning Lines off removes the lines at once and drops the waiting rebuild.

Subject: [PATCH 107/113] feat(flights): show the tracked aircraft's
 Planespotters photo in Contacts

Tracking a civil flight asks Planespotters for that aircraft's photo, once
per aircraft, straight from the browser. The CONTEXT panel's CONTACTS view
shows it under the flight's name with the photographer's credit, as a plain
link to the photo's page. Only images on plnspttrs.net and pages on
www.planespotters.net are ever shown or linked. Military aircraft and a
converted TR-3B are never looked up.

Flight lookups (type, route, photo) whose source failed temporarily are
asked again after a 60-second cool-down; an answer, found or not, and a
permanent refusal stay final for the session. A route belongs to the
callsign it was looked up for, so a callsign change drops the old route.

Browser QA scripts that track a flight answer the photo lookup themselves,
so they never call the third party.

-- **adsbdb enrichment.** `/api/adsbdb` resolves an ICAO hex to aircraft type, model name and registration, and the tracked flight's callsign to an airline and an origin/destination pair. Fan-out is deliberately small because adsbdb is a free community API that publishes no quota: at most 4 requests in flight, dispatches dripped to roughly 5/s, and each key asked for at most once per session, with route lookups reserved for the tracked aircraft. The dev-server proxy caches each key for 24 hours in `.gev-cache/adsbdb.json`, negative answers included, so fresh entries survive server restarts. That gitignored cache remains local to the deployment and is not bundled with this repo. adsbdb publishes no general service license; its README says the route data may not be copied, published, or incorporated into other databases without the explicit permission of David J Taylor, Edinburgh. Deployers are responsible for obtaining any permission their use requires. Enrichment is best-effort and fail-silent — a flight that gets no answer keeps what the flight feed already gave it.

Deployers are responsible for obtaining any permission their use requires. Enrichment is best-effort and fail-silent — a flight that gets no answer keeps what the flight feed already gave it.
+- **Planespotters photos.** When you track an aircraft, the browser asks `https://api.planespotters.net/pub/photos/hex/{hex}` directly (the API answers cross-origin, so no key and no server proxy are involved) for that aircraft only, once per hex per session, through the same enrichment queue as adsbdb, with an 8-second timeout. A miss is remembered for the session; a request that failed temporarily (an outage, the timeout or a rate limit) may be asked again after a 60-second cool-down while the aircraft stays tracked, as for the flights layer's other enrichment. Either way no photo shows meanwhile. The first photo whose image is an `https://` URL on `*.plnspttrs.net`, whose page is an `https://www.planespotters.net` URL, and which names its photographer is shown in the CONTEXT panel's CONTACTS view, under the tracked flight's name (`src/ui/views/panels/AwarenessPanel.vue`), and nowhere else; a vessel, an installation, a military aircraft or a converted TR-3B has none, and a military aircraft or TR-3B is never looked up. Anything else is dropped, so the app never shows or links outside Planespotters (`src/data/planespottersPhoto.js`, also exported as `gods-eye-view/sources/planespotters` for servers that cache the lookup). The photo follows the attribution rules: the thumbnail is hotlinked from the URL the API gives (never copied or re-hosted), the photographer's name is visible text next to it ("Photo © {photographer}"), and the photo and credit are a plain link to the photo's Planespotters page with `target="_blank" rel="noopener"` and never `rel="nofollow"`.

 - **Launch Library 2.** `/api/launches` makes a server-side rolling-30-day query against the supported v2.3 detailed launch endpoint, caches successful responses for 15 minutes in memory and on disk, and serves the last successful response during a throttle or transient outage. Anonymous access is limited to 15 calls/hour; deployments can provide `LL2_API_TOKEN` for authenticated access. The Space Devs' published terms permit using and sharing the API data in any form, ask users not to forward it without adding value, disclaim complete accuracy, and encourage—but do not require—attribution. This app keeps a courtesy credit. Payload and stage/recovery records are shown only when supplied. Failed launches expose their source status and never receive fallback orbit geometry or a live/estimated marker. LL2 supplies launch context and event timing, not continuous ascent telemetry or live orbital state.
 - **TfL JamCams.** The camera list comes from the keyless `api.tfl.gov.uk` endpoint (an optional `TFL_APP_KEY` raises its rate limit); frames come from TfL's public S3 bucket. The "Powered by TfL Open Data" attribution is required by TfL's terms and is registered in the Data attribution popover.
 - **Ontario 511 CCTV.** The camera list comes from the `511on.ca/api/v2/get/cameras` endpoint, which now requires a free developer key (`ONTARIO_511_API_KEY`: sign up at 511on.ca/my511/register, then request it while logged in at 511on.ca/developers/doc; throttled to 10 calls a minute). Without the key the pack is skipped. Frames are server-registered still images under `511on.ca/map/Cctv/`. The source is live-fetched at runtime and attributed under the Open Government Licence - Ontario. Access is governed by Ontario 511's Developer's Access Agreement (511on.ca/developers/resources): the data stays under the Open Government Licence - Ontario unless otherwise specified; key requests are reviewed case by case and ask for the intended use and any third parties that will receive the data; attribution by link to 511on.ca is encouraged, and the Ontario 511 logo may not be altered or used to imply endorsement (this app links and shows no logo); and the data is provided "as is", a disclaimer distributors should pass on, which the credit does.

Subject: [PATCH 109/113] fix(voice): restore the globe-rotation import a main
 merge dropped

The earlier main merge replaced `import { interruptGlobeRotation } from
'../cameraVerbs.js'` with the displayText import while keeping the
`interruptGlobeRotation('voice-zoom-intent')` call, so voice zoom actions
threw ReferenceError. The same merge replaced main's Overpass reservation
paragraph in docs/CURRENT-STATE.md; restore it next to the new text.

it through normalizeAlprNode, so the tags are already one line and capped.
Drop the second pass in the tool, its duplicate test and the boundary entry,
