Merge main into feat/shipwrecks; move shipwrecks to token 00

Main's wildlife-sightings layer took share-link token 9, so shipwrecks
takes the next free token, 00. Locale, docs, format-scope and voice
manifest conflicts keep both sides. Ledger and registry tests now model
the ledger before shipwrecks took 00, and layer counts include both
new layers.

 - **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 sixteen registered 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 and YRT 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.

 - **Re:Earth Terrain.** Keyless (no API key). Used two ways: (1) `src/mapStackController.js` swaps in a `Cesium.CesiumTerrainProvider` pointed at Re:Earth's `cesium-mesh/ellipsoid` quantized-mesh endpoint for globe stacks without a Cesium ion token (e.g. OSM), replacing a flat `EllipsoidTerrainProvider`; falls back to the flat provider if the endpoint can't be reached. (2) The server-side `/api/terrain/heights` proxy (disk-cached, serve-stale) resolves per-point ellipsoidal ground height for entity placement. Both are best-effort with a keyless-safe fallback (bundled EGM96 geoid math) if Re:Earth is unreachable.
 - **OSRM on the FOSSGIS routing servers.** Keyless (no API key). Every route is requested by a person: clicking A and B in the Directions layer, or a voice "route from A to B". The server-side `/api/route` proxy sends an identifying `User-Agent`, pins the upstream host, accepts 2-12 coordinates, rejects any leg over 600 km or a total over 2,500 km, caps the buffered response at 8 MB, times the upstream out at 12 s, rate-limits per client, caches each route for 10 minutes, and coalesces identical requests that are in flight at the same time. Turn-by-turn maneuvers are asked for only when a caller wants them (`steps=1`), so the callers that do not read them send the smaller request. The "fix the map" link the policy asks for is in the Data attribution popover beside the OpenStreetMap credit.
 - **FAA Special Use Airspace.** Keyless. `/api/drone-airspace` queries the public FAA AIS FeatureServer for prohibited (P) and restricted (R) zones only — not MOAs, TFRs or other SUA types — with simplified geometry, a body cap, paging, a one-hour cache and stale-on-error. The layer is US coverage, informational only, and is not a substitute for B4UFLY, LAANC or a preflight briefing. Data is fetched at request time and never stored or redistributed. US government public domain; courtesy attribution is registered in the Data attribution popover.
+- **iNaturalist.** Keyless. `/api/inaturalist/observations` returns cached random view samples (newest first globally), at most 200 per request. Recency uses observation time: the v1 `d1` filter and a rolling 48 h cutoff (whales 7 d); date-only rows qualify when their day starts within the window. Observation caches last 5 min (global 10 min), with stale fallback ≤1 h. `/api/inaturalist/grid` supplies density counts, cached 15 min. Both share a paced queue capped at 60/min and 8,000/day; only request counters persist in `.gev-cache/`. The server caches projected records, never raw responses. Private records are excluded; obscured coordinates become 0.2° cells. Observer identity is retained only for photo attribution. Eligible photos load directly from `inaturalist-open-data.s3.amazonaws.com`, with creator credit on ambient cards and creator/licence on selection. Per-record licences and noncommercial restrictions apply as listed above. Attribution appears in the layer row and Data attribution popover. Coverage follows community observations, not a census; Acartia adds Salish Sea marine mammals.
+- **iNaturalist grid (cell schema risk).** `/api/inaturalist/grid` shares observation-date, taxa, quality, pacing and budget rules with observations. A strict 64×64 UTFGrid schema guard fails closed; only logical-cell keys, counts and coordinates survive projection. Raw tiles, observation identifiers and free text are not retained. Projected tiles use a 400-entry LRU, 15-minute freshness and at most one hour of stale fallback. Views request at most six tiles; cached and adjacent-zoom coverage publishes before network waits, independently of observation pages. Cells supply a noninteractive density glow ranked within the view, from teal to amber with mono/CRT support. Every sighting badge comes from a real observation at its public position. Counts describe observations, not a population census. The endpoint is documented in the v1 and v2 API docs as “Grid Tiles UTFGrid” (`/grid/{z}/{x}/{y}.grid.json`), but its per-cell records are not specified; schema drift disables grids until revalidated. See `docs/KNOWN-ISSUES.md`.
+- **Acartia.** Keyless. `/api/acartia/sightings` reads the current 7-day marine-mammal feed for ALL, MAMMALS and WHALES views intersecting 45.5–50.5° N, 126–121° W in the Salish Sea. WHALES accepts recognized cetaceans; other identified marine mammals appear under ALL/MAMMALS. The server rounds positions to 0.01° and drops comments before caching projected records (10 min fresh, stale ≤24 h); raw responses are not retained. Selected text cards credit the reporting provider under CC BY 4.0 and show Be Whale Wise guidance. `/sightings/current` answers without a key today, but Acartia's README asks API users to create an account and generate an API key on the [Acartia dashboard](https://acartia.io/) and to follow its [community guidelines](https://acartia.io/register). Attribution also appears in the layer row and Data attribution popover. Opportunistic sightings, not a census.
 - **Mapped installations.** OpenFreeMap military polygons use a bundled Overture/OSM name index; wide views show named points. Optional operator-configured Overpass and explicit Google Places searches keep their own source paths. Mapped data does not establish current activity or complete coverage.
 - **Place search.** Named-place fly-to uses Google Geocoding when a Maps key is configured, then Photon (`PHOTON_URL`; unset uses the public instance, empty disables it), then `/api/geocode` (Nominatim search) when neither answers. `/api/geocode` and the voice outline route `/api/geocode/outline` share one Nominatim queue (`NOMINATIM_URL`; unset, empty and invalid values disable it; an operator must explicitly select an authorized endpoint): one request at a time at least 1.1 s apart, an identifying `User-Agent` and `Referer`, a short queue that refuses a burst, a pause after 429/403/5xx answers (honouring `Retry-After` in full), at most one retry after a network failure, and a per-install daily cap on public-instance requests (`NOMINATIM_DAILY_CAP`, default 50). Processes using the same installation state file hold one lock through the actual fetch invocation and recording the next public start, with the daily slot persisted before invocation; restarts share that count, spacing and any pause. An unfinished dispatch marker fails closed until operator recovery; it is never automatically reclaimed. Public access fails closed if the state file cannot be read, locked, written or semantically validated. This coordination does not span independent installations or state directories and does not establish an application-wide public-service allowance or authorize public use. An operator-selected non-public endpoint is outside the public cap, spacing and durable-state requirement; an upstream cooldown is kept with the endpoint that returned it rather than leaking across operator URLs. Answers are cached on disk (outlines 90 days, places 30 days, no-results 24 hours); failures are not cached. Outlines are looked up only for an explicit ask, after bundled data and any configured Overpass, and only results whose type suits the ask are used. Administrative outline responses expose country/admin-1/admin-2 identity only when the selected Nominatim row has a recognized, unambiguous address type consistent with its own name; numeric rank, ambiguous types, missing fields and contradictory names do not manufacture identity. It is not used for systematic or bulk queries.
 - **Street and building outlines.** Voice street highlights, pointed-at buildings and grounds use the OpenFreeMap vector tiles the traffic layer already loads. Traffic and outlines share one bounded pending fetch/decode owner per immutable XYZ tile; materialized outline geometry is charged to the retained-byte ceiling and capped by coordinate count. Consumer result caches and request lifetimes remain independent, while eviction or explicit teardown cancels queued idle projections and releases their decoded owner. No Overpass request is made unless `OVERPASS_UPSTREAMS` is configured. Named grounds require a returned name matching the selected place, except that an ask whose head noun names a kind of grounds (a school, university or college, hospital, cemetery, stadium or zoo) may use the part of the smallest unnamed tile area of that class that holds the resolved place; a differently named area never answers. Other anonymous landcover polygons cannot establish identity, so unsupported grounds stay unavailable rather than borrowing a nearby POI name.
