São Paulo, Rio de Janeiro, Salvador, Recife, Porto Alegre, Brasília and
Curitiba run on the same PBSC platform as the existing Austin, Honolulu
and Chattanooga entries, so they need no new feed handling and no proxy
allowlist change — isAllowedGbfsHost already accepts *.publicbikesystem.net.

These are the layer's first stations outside the United States: 1,017
stations across the seven systems.

Subject: [PATCH 02/76] feat(cctv): enrich identified cameras with datasheet
 FOV + specs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

When a CCTV source pack (or a seed) names its hardware `model`, resolve it
against a camera-model spec table: the coverage frustum then uses the
manufacturer's horizontal FOV instead of the pose estimate, and the HUD meta
line gains the model's resolution, night-vision, and PTZ specs. Cameras with
no identified model are unchanged — unknown never implies anything, matching
the layer's existing honesty about RAW PRIOR poses.

Spec records are vendored verbatim from the CCTV Camera Database
(https://github.com/ch-bas/cctv-camera-database, CC0-1.0), an open dataset of
12,000+ camera models transcribed from manufacturer datasheets. This lands a
small starter table plus the join + parsing helpers; source packs that publish
their hardware can grow it. Records describe camera products (optics,
resolution, night vision) only — no endpoints or access data.

- src/layers/cctv/modelSpecs.js: spec table, case-insensitive/alias lookup,
  wide-end FOV parser, HUD summary formatter
- src/layers/cctv/modelSpecs.test.mjs: lookup/alias/unknown, FOV parsing
  across the real fov string shapes, summary rendering
- src/layers/cctv/catalog.js: apply enrichment in both catalog builders
- src/layers/cctv/presentation.js: label a datasheet FOV, append the spec
  summary, and pass fovSource + spec through the public camera state

Subject: [PATCH 03/76] feat(cctv): vendor the model specs the integrated
 catalogs publish

Grow the enrichment table from the 4-model starter to the hardware the
currently integrated public catalogs actually publish, so identified
cameras render datasheet FOV cones and spec cards instead of estimates:

- King County (WA) road cameras: Cohu 3950 / 3960 (3965) / 3920 iDome
  (3925), Bosch AUTODOME IP 5000i.
- Sarasota County (FL) + Sioux Falls (SD) open data: Bosch AUTODOME IP
  starlight 7000i / starlight 7000 HD / dynamic 7000 HD, the VG4 AUTODOME
  (500i), Bosch AUTODOME 800 (VG5-836), and Axis Q6155-E, Q6054-E,
  Q6000-E Mk II, and P3707-PE.

All records are vendored verbatim from the CCTV Camera Database (CC0),
each transcribed from a manufacturer datasheet. Analog Cohu positioners
carry no fov_deg (their datasheets publish none), so they enrich the HUD
specs without a datasheet cone; every other model carries a real FOV.

Adds a test asserting the vendored table covers each integrated catalog's
published hardware strings.

Subject: [PATCH 04/76] feat(cctv): resolve verbose registry model strings via
 token fallback
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some catalogs publish a full product title rather than the bare model, e.g.
"AXIS Q6155-E PTZ Dome Network Camera" — which the exact model/alias match
misses. Add a fallback: after the exact match, scan for a record whose
DISTINCTIVE token (a >=4-char model/alias word containing a digit or hyphen,
so "dome"/"network"/"ptz"/"hd" never qualify) appears as a whole word in the
query. The most specific (longest) matched token wins; if two records tie on
the longest matched token the result is ambiguous and returns null, so the
lookup never guesses. Exact matches are unchanged and still take precedence.

Subject: [PATCH 05/76] fix(cctv): keep estimated FOV for PTZ/varifocal
 hardware; carry datasheet range as capability

A PTZ/varifocal datasheet FOV is a capability range, not the lens's
current zoom, so replacing the frustum's estimate with its wide end
presented unknown optical state as known. Parse the full horizontal
range (ignoring vertical, "combined" panoramic and lens-note figures),
carry it as specFovMinDeg/specFovMaxDeg, and substitute the datasheet
FOV only for fixed single-lens hardware. The HUD labels the range as
capability beside the estimate. This also stops the Q6000-E Mk II's
"360 combined" figure from being read as a 360-degree lens.

The proxy already restricted WHERE it would go — https, an allowlisted host, a
station_information/station_status path, no redirects, a 12-second deadline and
a 5 MB body cap — but nothing restricted HOW OFTEN, so the dev server would
relay an unbounded stream of requests at a third-party bikeshare operator on
any caller's behalf, one outbound fetch and one timeout timer each.

Admit 120 requests/minute per client address, global backstop 3x, refused with
429 and `Retry-After` before the target is even parsed. The ceiling comes from
the layer's own demand: `src/layers/bikeshare/registry.js` catalogues 15
systems, station information is cached per city after its first fetch, and
station status refreshes once per city every STATUS_POLL_MS (60s) with
in-flight requests deduplicated — about 15 requests a minute with everything
in range, so 120 is eight times a maximal session.

The method, host, path, redirect, deadline and size guards are unchanged.

From bde1e430efdee543f5a9ff88e341843d8569c2a9 Mon Sep 17 00:00:00 2001
From: Meir Michanie <meirm@cyborg.fi>
Date: Thu, 24 Sep 2026 20:03:23 +0200
Subject: [PATCH 08/76] feat(i18n): locale core + English catalogs + parity
 gates

Add the i18n foundation: src/i18n/locale.js (locale resolution with a
configurable GEV_DEFAULT_LOCALE / GEV_SECONDARY_LOCALE pair, guarded
preference storage, one-shot ?lang= override, <html lang>/<html dir>
metadata) and src/i18n/index.js (catalog registry, t(), Intl formatters,
applyDocumentTranslations, persistLocaleAndReload).

English is the only shipped locale in this PR: the four en catalogs
(shell/cockpit/layers/setup) are the reference and the always-shipped
fallback, the built-in pair degenerates to en-only, and English output
is byte-identical to the strings these replace.

Parity gates land with the core (catalog key/placeholder/plural-shape
parity, markup coverage of every data-i18n* attribute, repair-pass
anchors pinning en byte-identity); additional locales ship as stacked
follow-up PRs through the recipe in docs/TRANSLATORS.md.

Rebased onto current main: the client defines live in build/vite.js /
server/standalone/vite.config.js as before.

Subject: [PATCH 09/76] docs(cctv): refresh the CCTV Camera Database size in
 the model-specs module

The dataset has grown from 12,000+ to 28,000+ camera models (v2.26.0, 75%
with a field of view). The 17 vendored records are unchanged in v2.26.0.

Subject: [PATCH 10/76] =?UTF-8?q?feat(i18n):=20presentation=20extraction?=
 =?UTF-8?q?=20=E2=80=94=20t()=20call=20sites,=20data-i18n=20templates,=20l?=
 =?UTF-8?q?ocale=20selector?=
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Route every application-owned presentation string through the i18n
core: t() call sites across the app/layers/ui/data/voice surfaces,
data-i18n* attributes in the src/ui/templates/*.html markup (applied at
boot by applyDocumentTranslations from src/standalone/application.js),
and the dock locale selector (runtime-rendered from the offered pair —
a single EN button while only English ships).

Rebased onto current main, where the extraction follows the module
splits: the shell wiring now lands in the owner modules
(panelChrome, visualSettings, locationNavigation, shareRestoration,
shellFeedback, applicationShell) and the voice status corpus in the
realtime* modules; scene status lives in director.js +
playbackAdapter.js.

Modules shared with the node runtime (loadingFeedback,
installationFeedback, regionalModel, keySetupCore, vessels ingestion)
stay environment-neutral English and localize at their browser render
sites (chip maps in shellFeedback/installations controls, the weather
table in cockpitBriefing, keySetupRequirementEnvVars compositions), so
the package-boundary graph stays clean; the browser boundary groups
now own the i18n modules they reach (scripts/package-boundaries.json).

Subject: [PATCH 11/76] docs(i18n): translator's guide for the en-only
 foundation, current-state and changelog
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

docs/TRANSLATORS.md is rewritten for the foundation state: English
shipped, and the locale-addition recipe front and center — the
one-PR-per-locale procedure (catalogs, registration, CATALOG_LOCALES,
pair behavior, parity gates). CURRENT-STATE.md documents the subsystem
(file map, resolution order, selector, gates, deferrals) and the
CHANGELOG records the foundation.

+### Internationalization / catalog locales (September 2026)
+
+The application-owned UI is fully extracted into message catalogs; **en**
+is the only shipped locale in this foundation state — additional locales
+land as stacked follow-up PRs, one per locale (Spanish first), each
+following the locale-addition recipe in
+[`docs/TRANSLATORS.md`](./TRANSLATORS.md). English is the default, the
+source catalog, and the fallback. The subsystem lives in `src/i18n/`:
+
+- **File map.** `src/i18n/locale.js` owns locale resolution, guarded storage
+  (`gev:locale:v1`), the one-shot `?lang=` override, and `<html lang>`/`<html
+  dir>` metadata. `src/i18n/index.js` owns the catalog registry, `t()`
+  (interpolation + `Intl.PluralRules` plural selection), `formatNumber` /
+  `formatDate`, `applyDocumentTranslations()`, and
+  `persistLocaleAndReload()`. The shipped catalog is four flat message maps
+  — `src/i18n/locales/en/{shell,cockpit,layers,setup}.js`, 912 keys (shell
+  34, cockpit 369, layers 388, setup 121). Plural entries are the en
+  `{ one, other }` shape; a future locale may add only cardinal categories
+  `Intl.PluralRules` reports valid for it, and an entry lacking the selected
+  category degrades to `other` at runtime. Locale-code normalization
+  (`es-MX`/`es_419` → `es`, plus fr/ru/uk and variants) ships ahead of the
+  locales on purpose: knowing a code is hygiene, shipping is catalog-driven
+  through `CATALOG_LOCALES`.
+- **Selector.** The command dock carries a compact locale switch: a static
+  `.dock-locale-switch` group container in `index.html` whose buttons
+  (`.dock-locale-btn`) are rendered at runtime by `src/ui/applicationShell.js`
+  `_initLocaleSelector()` — one per locale in the configured pair; while
+  only English ships that is a single EN button. A click persists the
+  choice and reloads the page with the hash preserved, so no live re-apply
+  of already-rendered dynamic panels is needed.
+- **Locale pair config.** `GEV_DEFAULT_LOCALE` and `GEV_SECONDARY_LOCALE` in
+  `.env`, injected as `import.meta.env` defines by `vite.config.js`; both
+  values are validated against the shipped catalogs (`CATALOG_LOCALES`),
+  and the offered set is `dedup([default, secondary, 'en'])`. While English
+  is the only shipped catalog the built-in pair is en-only, so every
+  configuration degenerates to a single offered locale; an invalid,
+  unshipped, or degenerate configured pair falls back to that built-in
+  en-only shape (dev-only warn). The first secondary-locale PR restores the
+  built-in en+es pair.
+- **Resolution order.** `?lang=<locale>` (search string only; never
+  persisted, never written into share links; stripped by
+  `persistLocaleAndReload`; accepted only for offered locales) → stored
+  `gev:locale:v1` (re-checked against the pair) →
+  `navigator.languages` (regional variants normalize to the primary tag:
+  `es-MX`/`es_419` → `es`) → the CONFIGURED default locale. Unsupported
+  values defer to the next
+  step rather than forcing English.
+- **Gates** (all under `node --test src/i18n/`, 40 tests):
+  `catalog.test.mjs` enforces per-locale key, placeholder-name, and
+  plural-shape parity with the strict exact-parity flip ON
+  (`REQUIRE_FULL_PARITY`; `GEV_I18N_REQUIRE_FULL_LOCALE_PARITY=0` opts out
+  for staged work; the loops are vacuous while only en ships — each locale
+  PR meets them from day one);
+  `markupCoverage.test.mjs` requires every `data-i18n*` attribute in
+  `index.html` to resolve in every shipped catalog and rejects unknown attribute
+  spellings; `i18n.test.mjs` pins precedence, guards, fallback,
+  interpolation, the plural-selection contract (synthetic missing-category
+  degradation; real-catalog plural pins arrive with each locale PR), and
+  DOM application; `repairPass.test.mjs` anchors en byte-identity for
+  extracted literals and rejects a locale-scoped CCTV wrap rule shipping
+  ahead of its locale (per-locale value anchors arrive with each locale
+  PR).
+- **Accepted deferrals (do not "fix" silently):**
+  - The military-awareness subject header literal `FLIGHT / VESSEL WINDOW`
+    (`src/data/militaryAwareness.js`) stays English; the literal is
+    test-pinned in `src/data/militaryAwareness.test.mjs`.
+  - The visible cockpit-brief tab tokens `SIG` / `NEWS` / `LOCAL`
+    (`index.html`) stay untranslated to match the runtime keys; their
+    `aria-label`s ARE localized (`cockpit.brief.tab*AriaLabel`).
+  - `src/voice/gevActions.js` tool-result confirmation strings stay English
+    by contract (voice tool schemas and spoken confirmations are
+    keep-English; see the Keep-English boundary in `docs/TRANSLATORS.md`).
+  - Number formatting is still the pre-i18n `toLocaleString` policy at:
+    `src/ui.js:1442`, `src/data/satellites.js:829`,
+    `src/data/flights.js:436` (`'en-US'` pinned), and
+    `src/data/rocketLaunches.js:2281/2299/2364/2371/2374`
+    (default-locale). A locale-aware number-format policy is deferred; the
+    `formatNumber` helper exists in `src/i18n/index.js` when that lands.
+
+### Overpass proxy mirror rotation (September 2026)
+
+- `/api/overpass` fans out across four public mirrors. `overpassPayloadIsData()` governs cache reads, writes, and stale fallback: only a 2xx that is neither rate-limited nor a body-level runtime error qualifies. Previously stored refusals are ignored on both fresh and stale reads, so upgrading does not require manually clearing the disk cache.
+- HTTP refusals such as 406 now rotate alongside the existing network, rate-limit, and runtime-error cases. A refusal from one mirror no longer prevents reaching healthy alternatives or persists under the seven-day road/month-long boundary cache TTLs. Concurrent identical queries share one mirror sequence; if it fails, both the initiating and joined callers can use the same last-good data.
+- A refusal every mirror agrees on is still reported with the first mirror's status and body, so a genuinely malformed query says what upstream said — but only after every mirror has had the chance to answer it. `fetchOverpassPayload` takes injectable endpoints and fetch so the rotation is tested without a live mirror (`src/overpassProxy.test.mjs`).
+
+### Share-link v2 layer state (August 2026)
+
+- Generated share links use a deterministic v2 hash. Existing camera, visual,
+  HUD, detection, post-processing, celestial, scope, and map-stack fields remain,
+  with compact fields for enabled layers, allowlisted layer options, panel state,
+  and the active preset's allowlisted shader controls. An absent layer field uses
+  deterministic defaults; an explicit empty field means no enabled layers.
+- The registry seals only after all 16 production layers register, and every
+  layer has an explicit serialization disposition. Unknown enabled-layer tokens
+  reject the layer payload; unknown option tokens are ignored. Restoration
+  settles independently per layer so one failed or unavailable source cannot
+  block its siblings.
+- Stable visible options are limited to aircraft 3D mode, selected civilian and
+  military flight IDs, Satellite catalog and selection, CCTV coverage/projection/
+  auto-hop, and Radio filter/volume. Playback and tuning, live-data health,
+  calibration, caches, lifecycle state, temporary Context ownership, and derived
+  effects are deliberately excluded. Radio restore never selects or plays a
+  station.
+- Normal loads restore the last successful explicit UI, voice, or tool choice
+  from versioned local storage. Any valid camera share wins for the current load
+  without overwriting recipient preferences. Restore ownership is split by
+  visibility, option/selection, camera, visual, map, and individual panel lane:
+  a newer explicit action supersedes only the field it owns. In particular,
+  navigation cannot turn unrelated layers off, and an option change cannot
+
+#### Keep-English adjudications (post-merge catch-ups)
+
+- `src/ui/visualPresets.js` `'ELASTIC'` — detection-allocation STRATEGY IDENTIFIER (persisted
+  under `gev:detection-allocation`, compared via `dataset.allocation ===`), not display copy.
+- `src/ui/layerPanel.js` guidance meta — the `{source} · {statusMessage}` composition uses a
+  locale-neutral interpunct; the statusMessage itself IS localized via `installationFeedback`.
+- `src/ui/mapSourceControls.js` `'...'` switching label and the orbit `'↻'` glyph —
+  punctuation/glyphs, identical across locales.

+# Translator's guide (i18n foundation — English shipped)
+
+This is the working guide for translating God's Eye View. The i18n
+foundation ships **English only**: the locale core, the English
+catalogs, and the parity gates are in, and every additional locale lands
+as its own stacked PR, one locale at a time, following the
+[locale-addition recipe](#the-locale-addition-recipe) below. That recipe
+is the deliberate design artifact of this phase — a locale is not
+"translated into the app", it is *shipped* through the same gate every
+time.
+
+## Which locale ships, and which pair is offered
+
+One catalog ships: **en** (source of truth and unconditional fallback).
+Shipping is catalog-driven (`CATALOG_LOCALES` in `src/i18n/locale.js`):
+while only English ships, the built-in locale pair is en-only and the
+dock language switch renders a single EN button. Which pair the app
+*offers* is configuration, not code: `GEV_DEFAULT_LOCALE` and
+`GEV_SECONDARY_LOCALE` in `.env`, injected into the browser via vite
+defines. Both values are validated against the shipped catalogs — an
+invalid, unshipped, or degenerate pair (e.g. the same locale twice)
+degenerates to the built-in en-only shape with a dev-server-only
+`console.warn`. English is always resolvable — it is the fallback
+catalog — even when not part of the configured pair.
+
+## How the catalog system works
+
+All application-owned UI text lives in four flat message catalogs (en
+today; one directory per locale once shipped):
+
+```text
+src/i18n/
+  locale.js                  pair config + resolution + storage + <html lang>/<html dir>
+  index.js                   catalog registry, t(), Intl formatters, DOM apply
+  locales/en/{shell,cockpit,layers,setup}.js
+```
+
+| Namespace | Surface |
+| --- | --- |
+| `shell.*` | Document chrome: title, dock actions, panels, global status chip, sync chips, toasts, locale selector |
+| `cockpit.*` | Cockpit HUD readouts, Context panel, CCTV scene summary, Display/panel chrome, visual presets, Radio utility |
+| `layers.*` | Data-layer presentation: layer names, feed-state labels, row meta, vessel/flight/satellite/mission/CCTV/Radio/awareness cards and readouts |
+| `setup.*` | First-run launcher, key setup (POWER UP), scenes/director status, map-stack chips |
+
+Each catalog file exports `NAMESPACE` and a default map of
+namespace-relative keys; `mergeNamespace()` prefixes them (`cockpit.…`)
+and `buildCatalog()` rejects duplicates. English is the default and the
+fallback locale: a key missing in another locale renders its English
+value (dev-server-only `console.warn`). The en catalogs hold 912 keys
+(shell 34, cockpit 369, layers 388, setup 121).
+
+## Key naming
+
+- Markup surfaces: `<namespace>.<surface>.<element>` — e.g.
+  `shell.panels.dataLayers`, `cockpit.readout.altitude`.
+- Runtime flows/states: `<namespace>.<flow>.<state>` — e.g.
+  `shell.status.loadingLiveData`, `layers.missions.telemetry.km`.
+- Names are semantic and stable. Never rename, reorder, or renumber an
+  existing key: `data-i18n` attributes and runtime `t()` call sites in other
+  files reference them.
+
+## The locale-addition recipe
+
+Every locale PR follows the same steps, in this order. Nothing here is
+optional — the gates below fail the build if a step is skipped.
+
+1. **Catalogs.** Copy `src/i18n/locales/en/` to
+   `src/i18n/locales/<code>/` and translate all four files
+   (`<code>` is the primary language tag: `es`, not `es-419`). Keep the
+   en key order, keep key names byte-identical, and translate VALUES
+   only. A locale may never carry a key en lacks.
+2. **Registration.** In `src/i18n/index.js`: add the four import lines
+   and one `<CODE>_NAMESPACES` array, then one entry in the `CATALOGS`
+   map. Registration is append-only; nothing else in the file changes.
+3. **Shipping.** Append `'<code>'` to `CATALOG_LOCALES` in
+   `src/i18n/locale.js`. This single constant is what makes the locale
+   normalizable-to-shipped: pair config, `?lang=`, storage, and the
+   selector all read from it. Regional variants (`es-MX`, `es_419`)
+   already normalize — locale-code hygiene is shipped ahead of the
+   locales on purpose.
+4. **Selector labels.** Append
+   `'locale.<code>.ariaLabel': 'Switch to <Language>'` to the `shell`
+   catalog of EVERY shipped locale (en included — the en catalog names
+   the new button; the new catalog names the English one).
+   `markupCoverage.test.mjs` requires a label for every shipped code in
+   every catalog, so this cannot be forgotten.
+5. **Plurals.** Plural entries are variant objects carrying a `{count}`
+   placeholder, selected per active locale through `Intl.PluralRules`.
+   English entries use `{ one, other }`. Your locale must keep every en
+   variant and may add ONLY categories `Intl.PluralRules` reports valid
+   for it (e.g. a Slavic locale adds `few`/`many`) —
+   `catalog.test.mjs` enforces this shape against the live ICU data.
+   Pin your locale's real-catalog plural agreement in
+   `src/i18n/i18n.test.mjs` (one/few/many/other counts where relevant).
+6. **Layout.** Prefer concise glossary-approved copy over CSS surgery;
+   fixed-width `nowrap` panels must be checked at narrow viewports. A
+   locale-scoped wrap rule (`html[lang='<code>'] .cctv-controls {
+   flex-wrap: wrap; }` in `src/ui/styles/cctv.css`) is added ONLY when
+   the locale demonstrably clips, with a comment recording the measured
+   widths — the English layout stays pixel-identical, and
+   `repairPass.test.mjs` rejects a wrap rule shipping ahead of its
+   locale.
+7. **Gates.** `node --test src/i18n/` must be green with the strict
+   parity gate ON: exact key-set equality with en, identical
+   placeholder names, plural-shape superset. While a new catalog is a
+   staged untranslated seed, CI may run with
+   `GEV_I18N_REQUIRE_FULL_LOCALE_PARITY=0` (subset mode) — record every
+   such flip here, and record the flip back.
+8. **Docs.** Add the locale's section + glossary to this file, note it
+   in `docs/CURRENT-STATE.md` (Internationalization) and `CHANGELOG.md`,
+   and update the shipped-locales wording in `.env.example`.
+
+## Append-only rules
+
+- New keys are appended to the END of the namespace file in EVERY
+  shipped locale directory in the same change. Never edit another
+  namespace's files, and never touch the registration arrays in
+  `src/i18n/index.js` without re-reading this guide first.
+- A fifth namespace is a last resort (prefer fitting one of the four); its
+  registration recipe is the same append-only pattern as a locale (step 2
+  of the recipe above), applied to every shipped locale at once.
+- Parity is enforced by tests, not goodwill: no locale may carry a key en
+  lacks, and every shared key must keep identical placeholder names
+  and a plural-variant set that includes every en variant plus only
+  categories `Intl.PluralRules` reports for that locale
+  (`src/i18n/catalog.test.mjs`).
+
+## Placeholder, plural, and typography rules
+
+- Interpolation uses named `{camelCase}` placeholders:
+  `'Flying to {place}…'`. The **same placeholder names must exist in
+  every locale** — the parity gate fails on a renamed `{name}` because
+  it would break interpolation at runtime.
+- Locale-aware numbers, dates, and relative times go through the
+  `formatNumber` / `formatDate` / `formatRelativeTime` helpers in
+  `src/i18n/index.js` — do not hand-format in a catalog call site.
+- Style: the English catalog is ALL-CAPS for tactical labels, readouts,
+  and status text; translations follow the same convention in their
+  script's norms. The `·` separator used between metadata segments is
+  part of the surface style and is reproduced in translations.
+- Instrument codes stay identical across languages; units (KTS, FT, km,
+  km²) are never translated.
+- Romance languages run ~25% longer than English and Slavic languages
+  compound that on multi-word tactical labels — plan string budgets and
+  check fixed-width panels before review (see step 6 above).
+
+## Keep-English boundary (summary)
+
+Never catalog these — they are contracts, not copy:
+
+- Internal layer IDs and registry keys (`military-installations`,
+  `ais-live-vessels`, stack ids).
+- Status enums and machine values (`FEED_STATE_LABELS` keys, lifecycle
+  states, detection/context modes) — translate only the final label at
+  the presentation boundary.
+- URL/hash contracts: share-link parameters, `?welcome=`, `?lang=`,
+  storage schemas.
+- API fields, voice tool names/schemas, `/api/setup/*` payloads.
+- Provider/dataset/product names, callsigns, vessel/satellite/place
+  names from data, news headlines, license/source attributions.
+- Console diagnostics, QA pin scripts, and existing exact-English test
+  expectations.
+- User-authored content (annotations, labels drawn from live data).
+
+Adjudicated exceptions live in "Internationalization" in
+[`docs/CURRENT-STATE.md`](./CURRENT-STATE.md) (accepted deferrals — do not
+"fix" them silently).
+
+## Glossary
+
+Approved recurring terms per locale. Each locale PR appends its
+ glossary here (English term · translation · catalog evidence) so later
+ translators reuse approved copy verbatim. None yet — the first entry
+ arrives with the first translated locale.
+
+## Running the i18n test gates
+
+```sh
+node --test src/i18n/            # 40 tests: core + pair config, catalog parity, markup coverage, repair-pass anchors
+npm test                         # full suite (see below for the known environmental caveat)
+```
+
+- `src/i18n/i18n.test.mjs` — resolution precedence, guarded storage,
+  fallback, interpolation, plural selection (contract + synthetic
+  missing-category degradation; real-catalog plural pins arrive with
+  each locale PR), DOM application.
+- `src/i18n/catalog.test.mjs` — key + placeholder + plural-shape parity for
+  every shipped locale against en, strict `REQUIRE_FULL_PARITY` gate
+  (vacuous while only en ships; each locale PR meets it from day one).
+- `src/i18n/markupCoverage.test.mjs` — every `data-i18n*` attribute in
+  `index.html` must resolve in every shipped catalog; unknown attribute
+  spellings fail loudly.
+- `src/i18n/repairPass.test.mjs` — byte-identity anchors for English
+  literals; per-locale value anchors arrive with each locale PR.
+
+Full-suite caveat: `src/devFreshDotenv.test.mjs`'s external-keys provenance
+test fails when a provider key (e.g. `OPENAI_API_KEY`) is exported in the
+running shell — an environmental false positive unrelated to i18n.

Subject: [PATCH 14/76] refactor(i18n): key messages by English text; add
 Russian

Replace the semantic keys with the English source text, so code reads as the
UI does and English needs no catalog: t('Save keys'), tn(count, one, other)
for plurals, msg() for text stored in data, and bare data-i18n* markup that
translates the element's own English. Other languages are one flat JSON each.

- Simplify src/i18n: drop namespaces, the configurable locale pair
  (GEV_DEFAULT_LOCALE / GEV_SECONDARY_LOCALE) and its build defines. Locale
  comes from ?lang=, the stored choice, then browser languages.
- Add scripts/i18n.mjs (npm run i18n): extracts every message from t/tn/msg
  and markup, and fails on missing, unused, placeholder-mismatched or
  wrongly-shaped plural entries. npm test runs it via catalog.test.mjs.
- Add Russian (src/i18n/locales/ru.json, 833 messages), started from the
  community catalog in #312 and reviewed against the current English.
- Fix data-i18n placed on parents that would wipe their children (cockpit
  LEVEL and local weather cells, first-run EXPLORE MANUALLY tile), and a
  doubled degree sign in the TRACK ACQUIRED signal.
- Rewrite docs/TRANSLATORS.md for the new workflow; drop sections the earlier
  merge resurrected in docs/CURRENT-STATE.md.

+- Interface localization, starting with Russian. UI text is marked with
+  `t()`, `tn()` (plurals) and `msg()` in code and `data-i18n*` in markup, keyed
+  by the English text itself; each language is one flat JSON catalog
+  (`src/i18n/locales/ru.json`). The language comes from `?lang=`, the EN/RU
+  switch in the Visual Presets dock, then the browser language; English stays
+  the default and the fallback. `npm run i18n`, also run by `npm test`, fails on
+  missing, unused or broken translations. Built on the i18n foundation by
+  @meirm (#601), with the Russian catalog started from #312.

-land as stacked follow-up PRs, one per locale (Spanish first), each
-following the locale-addition recipe in
-[`docs/TRANSLATORS.md`](./TRANSLATORS.md). English is the default, the
-source catalog, and the fallback. The subsystem lives in `src/i18n/`:
+Shipped locales: **en** (source and fallback) and **ru**. The code lives in
+`src/i18n/`; the contributor workflow is in [`docs/TRANSLATORS.md`](./TRANSLATORS.md).
 
-- **File map.** `src/i18n/locale.js` owns locale resolution, guarded storage
-  (`gev:locale:v1`), the one-shot `?lang=` override, and `<html lang>`/`<html
-  dir>` metadata. `src/i18n/index.js` owns the catalog registry, `t()`
-  (interpolation + `Intl.PluralRules` plural selection), `formatNumber` /
-  `formatDate`, `applyDocumentTranslations()`, and
-  `persistLocaleAndReload()`. The shipped catalog is four flat message maps
-  — `src/i18n/locales/en/{shell,cockpit,layers,setup}.js`, 912 keys (shell
-  34, cockpit 369, layers 388, setup 121). Plural entries are the en
-  `{ one, other }` shape; a future locale may add only cardinal categories
-  `Intl.PluralRules` reports valid for it, and an entry lacking the selected
-  category degrades to `other` at runtime. Locale-code normalization
-  (`es-MX`/`es_419` → `es`, plus fr/ru/uk and variants) ships ahead of the
-  locales on purpose: knowing a code is hygiene, shipping is catalog-driven
-  through `CATALOG_LOCALES`.
-- **Selector.** The command dock carries a compact locale switch: a static
-  `.dock-locale-switch` group container in `index.html` whose buttons
-  (`.dock-locale-btn`) are rendered at runtime by `src/ui/applicationShell.js`
-  `_initLocaleSelector()` — one per locale in the configured pair; while
-  only English ships that is a single EN button. A click persists the
-  choice and reloads the page with the hash preserved, so no live re-apply
-  of already-rendered dynamic panels is needed.
-- **Locale pair config.** `GEV_DEFAULT_LOCALE` and `GEV_SECONDARY_LOCALE` in
-  `.env`, injected as `import.meta.env` defines by `vite.config.js`; both
-  values are validated against the shipped catalogs (`CATALOG_LOCALES`),
-  and the offered set is `dedup([default, secondary, 'en'])`. While English
-  is the only shipped catalog the built-in pair is en-only, so every
-  configuration degenerates to a single offered locale; an invalid,
-  unshipped, or degenerate configured pair falls back to that built-in
-  en-only shape (dev-only warn). The first secondary-locale PR restores the
-  built-in en+es pair.
-- **Resolution order.** `?lang=<locale>` (search string only; never
-  persisted, never written into share links; stripped by
-  `persistLocaleAndReload`; accepted only for offered locales) → stored
-  `gev:locale:v1` (re-checked against the pair) →
-  `navigator.languages` (regional variants normalize to the primary tag:
-  `es-MX`/`es_419` → `es`) → the CONFIGURED default locale. Unsupported
-  values defer to the next
-  step rather than forcing English.
-- **Gates** (all under `node --test src/i18n/`, 40 tests):
-  `catalog.test.mjs` enforces per-locale key, placeholder-name, and
-  plural-shape parity with the strict exact-parity flip ON
-  (`REQUIRE_FULL_PARITY`; `GEV_I18N_REQUIRE_FULL_LOCALE_PARITY=0` opts out
-  for staged work; the loops are vacuous while only en ships — each locale
-  PR meets them from day one);
-  `markupCoverage.test.mjs` requires every `data-i18n*` attribute in
-  `index.html` to resolve in every shipped catalog and rejects unknown attribute
-  spellings; `i18n.test.mjs` pins precedence, guards, fallback,
-  interpolation, the plural-selection contract (synthetic missing-category
-  degradation; real-catalog plural pins arrive with each locale PR), and
-  DOM application; `repairPass.test.mjs` anchors en byte-identity for
-  extracted literals and rejects a locale-scoped CCTV wrap rule shipping
-  ahead of its locale (per-locale value anchors arrive with each locale
-  PR).
-- **Accepted deferrals (do not "fix" silently):**
-  - The military-awareness subject header literal `FLIGHT / VESSEL WINDOW`
-    (`src/data/militaryAwareness.js`) stays English; the literal is
-    test-pinned in `src/data/militaryAwareness.test.mjs`.
-  - The visible cockpit-brief tab tokens `SIG` / `NEWS` / `LOCAL`
-    (`index.html`) stay untranslated to match the runtime keys; their
-    `aria-label`s ARE localized (`cockpit.brief.tab*AriaLabel`).
-  - `src/voice/gevActions.js` tool-result confirmation strings stay English
-    by contract (voice tool schemas and spoken confirmations are
-    keep-English; see the Keep-English boundary in `docs/TRANSLATORS.md`).
-  - Number formatting is still the pre-i18n `toLocaleString` policy at:
-    `src/ui.js:1442`, `src/data/satellites.js:829`,
-    `src/data/flights.js:436` (`'en-US'` pinned), and
-    `src/data/rocketLaunches.js:2281/2299/2364/2371/2374`
-    (default-locale). A locale-aware number-format policy is deferred; the
-    `formatNumber` helper exists in `src/i18n/index.js` when that lands.
-
-### Overpass proxy mirror rotation (September 2026)
-
-- `/api/overpass` fans out across four public mirrors. `overpassPayloadIsData()` governs cache reads, writes, and stale fallback: only a 2xx that is neither rate-limited nor a body-level runtime error qualifies. Previously stored refusals are ignored on both fresh and stale reads, so upgrading does not require manually clearing the disk cache.
-- HTTP refusals such as 406 now rotate alongside the existing network, rate-limit, and runtime-error cases. A refusal from one mirror no longer prevents reaching healthy alternatives or persists under the seven-day road/month-long boundary cache TTLs. Concurrent identical queries share one mirror sequence; if it fails, both the initiating and joined callers can use the same last-good data.
-- A refusal every mirror agrees on is still reported with the first mirror's status and body, so a genuinely malformed query says what upstream said — but only after every mirror has had the chance to answer it. `fetchOverpassPayload` takes injectable endpoints and fetch so the rotation is tested without a live mirror (`src/overpassProxy.test.mjs`).
-
-### Share-link v2 layer state (August 2026)
-
-- Generated share links use a deterministic v2 hash. Existing camera, visual,
-  HUD, detection, post-processing, celestial, scope, and map-stack fields remain,
-  with compact fields for enabled layers, allowlisted layer options, panel state,
-  and the active preset's allowlisted shader controls. An absent layer field uses
-  deterministic defaults; an explicit empty field means no enabled layers.
-- The registry seals only after all 16 production layers register, and every
-  layer has an explicit serialization disposition. Unknown enabled-layer tokens
-  reject the layer payload; unknown option tokens are ignored. Restoration
-  settles independently per layer so one failed or unavailable source cannot
-  block its siblings.
-- Stable visible options are limited to aircraft 3D mode, selected civilian and
-  military flight IDs, Satellite catalog and selection, CCTV coverage/projection/
-  auto-hop, and Radio filter/volume. Playback and tuning, live-data health,
-  calibration, caches, lifecycle state, temporary Context ownership, and derived
-  effects are deliberately excluded. Radio restore never selects or plays a
-  station.
-- Normal loads restore the last successful explicit UI, voice, or tool choice
-  from versioned local storage. Any valid camera share wins for the current load
-  without overwriting recipient preferences. Restore ownership is split by
-  visibility, option/selection, camera, visual, map, and individual panel lane:
-  a newer explicit action supersedes only the field it owns. In particular,
-  navigation cannot turn unrelated layers off, and an option change cannot
-
-#### Keep-English adjudications (post-merge catch-ups)
-
-- `src/ui/visualPresets.js` `'ELASTIC'` — detection-allocation STRATEGY IDENTIFIER (persisted
-  under `gev:detection-allocation`, compared via `dataset.allocation ===`), not display copy.
-- `src/ui/layerPanel.js` guidance meta — the `{source} · {statusMessage}` composition uses a
-  locale-neutral interpunct; the statusMessage itself IS localized via `installationFeedback`.
-- `src/ui/mapSourceControls.js` `'...'` switching label and the orbit `'↻'` glyph —
-  punctuation/glyphs, identical across locales.
+- **Keys are the English text.** `t('Save keys')`, `tn(count, '{count} camera',
+  '{count} cameras')`, and `msg('Live Flights')` for text stored in data and
+  translated later. Markup opts in with `data-i18n` (element text) and
+  `data-i18n-title` / `-aria-label` / `-placeholder` (that attribute's English
+  value). English has no catalog; every other locale is
+  `src/i18n/locales/<code>.json`, and a missing entry falls back to English.
+- **Locale choice.** `?lang=` (one-shot) → stored choice (`gev:locale:v1`) →
+  `navigator.languages` → English. The EN/RU switch in the Visual Presets dock
+  stores the choice and reloads, so nothing re-renders live.
+- **Gate.** `npm run i18n` (and `src/i18n/catalog.test.mjs` under `npm test`)
+  extracts every message and fails on missing, unused, placeholder-mismatched or
+  wrongly-shaped plural entries.
+- **Not translated by design:** layer ids, share-link and hash parameters, API
+  fields, voice tool schemas, provider names, feed data (callsigns, vessel and
+  station names) and attribution.
+- **Gaps.** Strings added after #601's extraction (for example the Street Level
+  panel) are still raw English; there is no lint for unmarked UI text yet.

-# Translator's guide (i18n foundation — English shipped)
+# Translating God's Eye View
 
-This is the working guide for translating God's Eye View. The i18n
-foundation ships **English only**: the locale core, the English
-catalogs, and the parity gates are in, and every additional locale lands
-as its own stacked PR, one locale at a time, following the
-[locale-addition recipe](#the-locale-addition-recipe) below. That recipe
-is the deliberate design artifact of this phase — a locale is not
-"translated into the app", it is *shipped* through the same gate every
-time.
+Shipped languages: **English** (source and fallback) and **Russian** (`ru`).
 
-## Which locale ships, and which pair is offered
+## How it works
 
-One catalog ships: **en** (source of truth and unconditional fallback).
-Shipping is catalog-driven (`CATALOG_LOCALES` in `src/i18n/locale.js`):
-while only English ships, the built-in locale pair is en-only and the
-dock language switch renders a single EN button. Which pair the app
-*offers* is configuration, not code: `GEV_DEFAULT_LOCALE` and
-`GEV_SECONDARY_LOCALE` in `.env`, injected into the browser via vite
-defines. Both values are validated against the shipped catalogs — an
-invalid, unshipped, or degenerate pair (e.g. the same locale twice)
-degenerates to the built-in en-only shape with a dev-server-only
-`console.warn`. English is always resolvable — it is the fallback
-catalog — even when not part of the configured pair.
+The English text is the key. There is no English catalog: the code is the source.
 
-## How the catalog system works
-
-All application-owned UI text lives in four flat message catalogs (en
-today; one directory per locale once shipped):
-
-```text
-src/i18n/
-  locale.js                  pair config + resolution + storage + <html lang>/<html dir>
-  index.js                   catalog registry, t(), Intl formatters, DOM apply
-  locales/en/{shell,cockpit,layers,setup}.js
+```js
+t('Save keys'); // plain text
+t('Saved to {store}', { store }); // named placeholders
+tn(count, '{count} camera', '{count} cameras'); // count-dependent text
+msg('Live Flights'); // text kept in data, translated later by t()
 ```
 
-| Namespace | Surface |
-| --- | --- |
-| `shell.*` | Document chrome: title, dock actions, panels, global status chip, sync chips, toasts, locale selector |
-| `cockpit.*` | Cockpit HUD readouts, Context panel, CCTV scene summary, Display/panel chrome, visual presets, Radio utility |
-| `layers.*` | Data-layer presentation: layer names, feed-state labels, row meta, vessel/flight/satellite/mission/CCTV/Radio/awareness cards and readouts |
-| `setup.*` | First-run launcher, key setup (POWER UP), scenes/director status, map-stack chips |
+```html
+<span data-i18n>Normal</span>
+<button title="Pin visual presets" data-i18n-title>…</button>
+```
 
-Each catalog file exports `NAMESPACE` and a default map of
-namespace-relative keys; `mergeNamespace()` prefixes them (`cockpit.…`)
-and `buildCatalog()` rejects duplicates. English is the default and the
-fallback locale: a key missing in another locale renders its English
-value (dev-server-only `console.warn`). The en catalogs hold 912 keys
-(shell 34, cockpit 369, layers 388, setup 121).
+`data-i18n` translates the element's own text (put it on the element that holds the text, not on a parent with children). `data-i18n-title`, `data-i18n-aria-label` and `data-i18n-placeholder` translate that attribute's English value.
 
-## Key naming
+Every other language is one flat JSON file, `src/i18n/locales/<code>.json`, keyed by the English text:
 
-- Markup surfaces: `<namespace>.<surface>.<element>` — e.g.
-  `shell.panels.dataLayers`, `cockpit.readout.altitude`.
-- Runtime flows/states: `<namespace>.<flow>.<state>` — e.g.
-  `shell.status.loadingLiveData`, `layers.missions.telemetry.km`.
-- Names are semantic and stable. Never rename, reorder, or renumber an
-  existing key: `data-i18n` attributes and runtime `t()` call sites in other
-  files reference them.
+```json
+{
+  "Save keys": "Сохранить ключи",
+  "{count} cameras": {
+    "one": "{count} камера",
+    "few": "{count} камеры",
+    "many": "{count} камер",
+    "other": "{count} камеры"
+  }
+}
+```
 
-## The locale-addition recipe
+A `tn()` entry is keyed by the English plural form and holds one string per `Intl.PluralRules` category of that language. A missing entry falls back to English.
 
-Every locale PR follows the same steps, in this order. Nothing here is
-optional — the gates below fail the build if a step is skipped.
+The page picks its language from `?lang=`, then the choice stored by the EN/RU switch in the Visual Presets dock, then the browser languages, then English. Switching reloads the page.
 
-1. **Catalogs.** Copy `src/i18n/locales/en/` to
-   `src/i18n/locales/<code>/` and translate all four files
-   (`<code>` is the primary language tag: `es`, not `es-419`). Keep the
-   en key order, keep key names byte-identical, and translate VALUES
-   only. A locale may never carry a key en lacks.
-2. **Registration.** In `src/i18n/index.js`: add the four import lines
-   and one `<CODE>_NAMESPACES` array, then one entry in the `CATALOGS`
-   map. Registration is append-only; nothing else in the file changes.
-3. **Shipping.** Append `'<code>'` to `CATALOG_LOCALES` in
-   `src/i18n/locale.js`. This single constant is what makes the locale
-   normalizable-to-shipped: pair config, `?lang=`, storage, and the
-   selector all read from it. Regional variants (`es-MX`, `es_419`)
-   already normalize — locale-code hygiene is shipped ahead of the
-   locales on purpose.
-4. **Selector labels.** Append
-   `'locale.<code>.ariaLabel': 'Switch to <Language>'` to the `shell`
-   catalog of EVERY shipped locale (en included — the en catalog names
-   the new button; the new catalog names the English one).
-   `markupCoverage.test.mjs` requires a label for every shipped code in
-   every catalog, so this cannot be forgotten.
-5. **Plurals.** Plural entries are variant objects carrying a `{count}`
-   placeholder, selected per active locale through `Intl.PluralRules`.
-   English entries use `{ one, other }`. Your locale must keep every en
-   variant and may add ONLY categories `Intl.PluralRules` reports valid
-   for it (e.g. a Slavic locale adds `few`/`many`) —
-   `catalog.test.mjs` enforces this shape against the live ICU data.
-   Pin your locale's real-catalog plural agreement in
-   `src/i18n/i18n.test.mjs` (one/few/many/other counts where relevant).
-6. **Layout.** Prefer concise glossary-approved copy over CSS surgery;
-   fixed-width `nowrap` panels must be checked at narrow viewports. A
-   locale-scoped wrap rule (`html[lang='<code>'] .cctv-controls {
-   flex-wrap: wrap; }` in `src/ui/styles/cctv.css`) is added ONLY when
-   the locale demonstrably clips, with a comment recording the measured
-   widths — the English layout stays pixel-identical, and
-   `repairPass.test.mjs` rejects a wrap rule shipping ahead of its
-   locale.
-7. **Gates.** `node --test src/i18n/` must be green with the strict
-   parity gate ON: exact key-set equality with en, identical
-   placeholder names, plural-shape superset. While a new catalog is a
-   staged untranslated seed, CI may run with
-   `GEV_I18N_REQUIRE_FULL_LOCALE_PARITY=0` (subset mode) — record every
-   such flip here, and record the flip back.
-8. **Docs.** Add the locale's section + glossary to this file, note it
-   in `docs/CURRENT-STATE.md` (Internationalization) and `CHANGELOG.md`,
-   and update the shipped-locales wording in `.env.example`.
-
-## Append-only rules
-
-- New keys are appended to the END of the namespace file in EVERY
-  shipped locale directory in the same change. Never edit another
-  namespace's files, and never touch the registration arrays in
-  `src/i18n/index.js` without re-reading this guide first.
-- A fifth namespace is a last resort (prefer fitting one of the four); its
-  registration recipe is the same append-only pattern as a locale (step 2
-  of the recipe above), applied to every shipped locale at once.
-- Parity is enforced by tests, not goodwill: no locale may carry a key en
-  lacks, and every shared key must keep identical placeholder names
-  and a plural-variant set that includes every en variant plus only
-  categories `Intl.PluralRules` reports for that locale
-  (`src/i18n/catalog.test.mjs`).
-
-## Placeholder, plural, and typography rules
-
-- Interpolation uses named `{camelCase}` placeholders:
-  `'Flying to {place}…'`. The **same placeholder names must exist in
-  every locale** — the parity gate fails on a renamed `{name}` because
-  it would break interpolation at runtime.
-- Locale-aware numbers, dates, and relative times go through the
-  `formatNumber` / `formatDate` / `formatRelativeTime` helpers in
-  `src/i18n/index.js` — do not hand-format in a catalog call site.
-- Style: the English catalog is ALL-CAPS for tactical labels, readouts,
-  and status text; translations follow the same convention in their
-  script's norms. The `·` separator used between metadata segments is
-  part of the surface style and is reproduced in translations.
-- Instrument codes stay identical across languages; units (KTS, FT, km,
-  km²) are never translated.
-- Romance languages run ~25% longer than English and Slavic languages
-  compound that on multi-word tactical labels — plan string budgets and
-  check fixed-width panels before review (see step 6 above).
-
-## Keep-English boundary (summary)
-
-Never catalog these — they are contracts, not copy:
-
-- Internal layer IDs and registry keys (`military-installations`,
-  `ais-live-vessels`, stack ids).
-- Status enums and machine values (`FEED_STATE_LABELS` keys, lifecycle
-  states, detection/context modes) — translate only the final label at
-  the presentation boundary.
-- URL/hash contracts: share-link parameters, `?welcome=`, `?lang=`,
-  storage schemas.
-- API fields, voice tool names/schemas, `/api/setup/*` payloads.
-- Provider/dataset/product names, callsigns, vessel/satellite/place
-  names from data, news headlines, license/source attributions.
-- Console diagnostics, QA pin scripts, and existing exact-English test
-  expectations.
-- User-authored content (annotations, labels drawn from live data).
-
-Adjudicated exceptions live in "Internationalization" in
-[`docs/CURRENT-STATE.md`](./CURRENT-STATE.md) (accepted deferrals — do not
-"fix" them silently).
-
-## Glossary
-
-Approved recurring terms per locale. Each locale PR appends its
- glossary here (English term · translation · catalog evidence) so later
- translators reuse approved copy verbatim. None yet — the first entry
- arrives with the first translated locale.

-## Running the i18n test gates
+## The check
 
 ```sh
-node --test src/i18n/            # 40 tests: core + pair config, catalog parity, markup coverage, repair-pass anchors
-npm test                         # full suite (see below for the known environmental caveat)
+npm run i18n                      # what is missing, unused or broken, per language
+npm run i18n -- --missing ru      # missing ru entries as JSON, ready to translate
+npm run i18n -- --prune           # drop entries the code no longer uses
 ```
 
-- `src/i18n/i18n.test.mjs` — resolution precedence, guarded storage,
-  fallback, interpolation, plural selection (contract + synthetic
-  missing-category degradation; real-catalog plural pins arrive with
-  each locale PR), DOM application.
-- `src/i18n/catalog.test.mjs` — key + placeholder + plural-shape parity for
-  every shipped locale against en, strict `REQUIRE_FULL_PARITY` gate
-  (vacuous while only en ships; each locale PR meets it from day one).
-- `src/i18n/markupCoverage.test.mjs` — every `data-i18n*` attribute in
-  `index.html` must resolve in every shipped catalog; unknown attribute
-  spellings fail loudly.
-- `src/i18n/repairPass.test.mjs` — byte-identity anchors for English
-  literals; per-locale value anchors arrive with each locale PR.
+`npm test` runs the same check (`src/i18n/catalog.test.mjs`). It fails when a translation is missing, when an entry is no longer used, when placeholders differ from the English, or when a plural entry lacks a form.

-test fails when a provider key (e.g. `OPENAI_API_KEY`) is exported in the
-running shell — an environmental false positive unrelated to i18n.
+Changing English text changes its key: the old translation becomes unused and the new text shows as missing. Translate it and prune.
+
+## Fixing a translation
+
+Edit `src/i18n/locales/<code>.json` and run `npm run i18n`. To see your change, open the app with `?lang=<code>`.
+
+## Adding a language
+
+1. Create `src/i18n/locales/<code>.json`, fill it from `npm run i18n -- --missing <code>` (start from `{}`), and translate every entry.
+2. Import it in `src/i18n/index.js` and add it to `CATALOGS`.
+3. Add the code to `LOCALES` and its own-language name to `LOCALE_NAMES` in `src/i18n/locale.js`. Right-to-left languages also go in `RTL_LOCALES`.
+4. Add `src/i18n/locales/<code>.json` next to `ru.json` in `scripts/package-boundaries.json`.
+5. Run `npm run i18n` and `npm test`, then check the panels in the app at narrow widths.
+
+## Rules
+
+- Keep every `{placeholder}` exactly as in the English; you may move it.
+- UPPERCASE English stays UPPERCASE. Short labels, chips and HUD readouts should stay short; prefer an abbreviation over a wrapped line.
+- Keep the separators `·`, `—`, `→`, `↗`, `…`.
+- Leave product, provider and data names in their original form: Google Maps, Cesium ion, OpenAI, ChatGPT, NASA FIRMS, USGS, OpenSky, ADS-B, AIS, CCTV, HUD, TomTom, OpenStreetMap, Mapillary, and keyboard keys (Space, Esc, H, 1–9).
+- Units follow the language's convention (Russian: км, м/с, уз, фт).
+
+## Never translated
+
+These are contracts, not copy: layer ids and registry keys, status enums and other machine values (translate only the label shown for them), share-link and hash parameters, `?lang=`, storage schemas, API fields, voice tool names and schemas, provider and dataset names, data from feeds (callsigns, vessel, satellite, station and place names, headlines), attribution, console diagnostics, and user-authored content.

+# UI text and translation
+
+Every piece of text a user can see goes through `t()`, `tn()` or `msg()` in code, or a `data-i18n*` attribute in markup. The English text itself is the key. English needs no catalog; other languages live in `src/i18n/locales/<code>.json`. Translators work from [TRANSLATORS.md](./TRANSLATORS.md).
+
+## Which one to use
+
+|                                 | Translates                        | Use for                                       |
+| ------------------------------- | --------------------------------- | --------------------------------------------- |
+| `t(text, values)`               | now                               | any text shown right where it is written      |
+| `tn(count, one, other, values)` | now, picking the form for `count` | text that changes with a number               |
+| `msg(text)`                     | never: returns `text` unchanged   | text stored in data and passed to `t()` later |
+
+```js
+import { t, tn, msg } from '../i18n/index.js';
+
+status.textContent = t('Save keys');
+status.textContent = t('Saved to {store}', { store: storeLabel() });
+
+chip.textContent = tn(missing, '{count} KEY WAITING', '{count} KEYS WAITING');
+// en: 1 KEY / 3 KEYS     ru: 1 КЛЮЧ / 3 КЛЮЧА / 5 КЛЮЧЕЙ
+
+const FEED_STATE_LABELS = { loading: msg('LOADING'), stale: msg('STALE') };
+label.textContent = t(FEED_STATE_LABELS[state]);
+```
+
+`msg()` exists for two reasons. `npm run i18n` finds messages only as string literals inside `t(…)`, `tn(…)` and `msg(…)`, so `t(FEED_STATE_LABELS[state])` alone tells it nothing. And a `t()` call at module load runs before the page has picked its language, so it would freeze the English.
+
+## Markup
+
+```html
+<span data-i18n>Normal</span>
+<button title="Pin visual presets" data-i18n-title>…</button>
+<input placeholder="Search any location..." data-i18n-placeholder />
+```
+
+`data-i18n` replaces the element's text, so put it on the element that directly holds the text, never on a parent with child elements. `data-i18n-title`, `data-i18n-aria-label` and `data-i18n-placeholder` translate that attribute. Markup is translated once at boot, and switching language reloads the page.
+
+## Rules
+
+- **Pass literals.** `t('Close')`, not `t(label)` (unless `label` holds a `msg()` value) and never a template literal with `${…}`.
+- **Use placeholders, not concatenation.** `t('Flying to {place}…', { place })`, not `t('Flying to') + ' ' + place`. Word order differs between languages.
+- **Use `tn()` for counts**, not `count === 1 ? … : …`. Russian has three forms.
+- **Translate the label, not the value.** Layer ids, enums, share-link parameters, API fields, voice tool schemas and feed data (callsigns, vessel and place names) stay as they are; translate only the text shown for them.
+- **No `t()` at module top level.** Keep the English in `msg()` and call `t()` when rendering.
+- **Numbers and dates** go through `formatNumber`, `formatDate` and `formatRelativeTime` from `src/i18n/index.js`, which follow the active language.
+- **Identical English means identical translation.** If two places need different words, make the English differ.
+- **Text that should stay English** (a brand, a code, a unit symbol) is simply not wrapped.
+
+## After you add or change text
+
+```sh
+npm run i18n                     # shows what each language now lacks or no longer uses
+npm run i18n -- --missing ru     # the missing ru entries as JSON
+npm run i18n -- --prune          # drop entries whose English no longer exists
+```
+
+Changing the English changes the key, so the old translation goes unused and the new text shows as missing. Add the translation to `src/i18n/locales/ru.json` (or ask a translator), prune, and run `npm test`, which runs the same check and fails until every language is complete.
+
+To see a language, open the app with `?lang=ru`, or use the EN/RU switch in the Visual Presets dock.
+
+## Where things live
+
+| File                           | What it holds                                                                 |

 ## How it works
 
-The English text is the key. There is no English catalog: the code is the source.
-
-```js
-t('Save keys'); // plain text
-t('Saved to {store}', { store }); // named placeholders
-tn(count, '{count} camera', '{count} cameras'); // count-dependent text
-msg('Live Flights'); // text kept in data, translated later by t()

-```html
-<span data-i18n>Normal</span>
-<button title="Pin visual presets" data-i18n-title>…</button>
-```
-
-`data-i18n` translates the element's own text (put it on the element that holds the text, not on a parent with children). `data-i18n-title`, `data-i18n-aria-label` and `data-i18n-placeholder` translate that attribute's English value.
+The English text is the key: code calls `t('Save keys')`, and markup marks elements with `data-i18n`. How developers mark text is in [I18N.md](./I18N.md).
 
 Every other language is one flat JSON file, `src/i18n/locales/<code>.json`, keyed by the English text:

Subject: [PATCH 18/76] feat(i18n): Spanish catalog

Meir Michanie's Spanish translation from #602 (9d69e11, 4ba5d69), converted
to the English-keyed format: one entry per English message in
src/i18n/locales/es.json, translations unchanged. Also carries the es-only
CCTV control-row wrap rule.

Subject: [PATCH 19/76] feat(i18n): ship Spanish
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Register es next to ru (selector shows EN | ES | RU) and complete the
catalog against the current English: the 13 messages added since #602,
the "many" plural form Intl.PluralRules('es') selects for exact millions,
and fixes where the English had changed (e.g. "hace hace" in LIVE ·
updated, minutes written as metres). Terminology made consistent (buque,
aeronave, incendio activo); key names stay in English. Meir's wording is
kept everywhere else. Adds docs/translations/es.md.

+# Spanish (`es`)
+
+Catalog: `src/i18n/locales/es.json`. General rules: [TRANSLATORS.md](../TRANSLATORS.md).
+
+## Style
+
+- Neutral Spanish that reads naturally in Spain and Latin America; avoid regionalisms.
+- Address the user with informal "tú" imperatives: «Añade», «Activa», «Elige», «Pega», «Inténtalo de nuevo». Tooltips that name an action may use the infinitive: «Expandir el panel», «Restablecer la cámara».
+- Sentence case, not Title Case: "Live Flights" → «Vuelos en vivo». UPPERCASE English stays UPPERCASE: «EN VIVO», «SIN DATOS».
+- Quotes inside Spanish text are straight double quotes: «¿Eliminar el plano "{shot}"?». Questions and exclamations open with ¿ and ¡.
+- Short labels, chips and HUD readouts stay short. A standard abbreviation with a period beats a wrapped line: ANT., SIG., VEL., DIST., SINCR., cám., cob.
+- The HUD codes HDG, BRG, CRS, FOV, DEST, SPD, RANGE and ALT stay in English everywhere, as in cockpit avionics. Words used in a sentence are translated: heading → «rumbo», range → «alcance».
+- Keyboard keys stay in English: Space, Esc, Enter, Tab, Shift, H, 1–9 («Mantén pulsado Space para hablar»).
+- Units: km, m, km/h, m/s, kn (knots), ft (feet), h, min, s; in UPPERCASE text KM, KM/S, KN, FT, MIN, H. "m" is always metres, so minutes are «min» («hace 5 min»). MW stays MW. `°` and `%` stay.
+- "ago" goes before the time: «hace {count} min». When a placeholder already holds a localized "ago" text (`{age}`, `{ago}`), do not add «hace» again.
+- Spelling: «costo» (not «coste»).
+
+## Plurals
+
+A `tn()` entry needs three forms. `Intl.PluralRules('es')` picks:
+
+| Form    | Counts                                 | Example              |
+| ------- | -------------------------------------- | -------------------- |
+| `one`   | 1                                      | 1 cámara             |
+| `many`  | 1 000 000, 2 000 000… (exact millions) | 1 000 000 de cámaras |
+| `other` | everything else: 0, 2–999 999, 1.5…    | 3 cámaras            |
+
+The `many` form is the `other` text with «de» after the number: «{count} de cámaras cargadas», «{count} DE CLAVES EN ESPERA».

Subject: [PATCH 20/76] fix(i18n): translate visual preset parameter sliders
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The slider labels (Sensitivity, Bloom, Pixelation, …) live in the shader
modules and were rendered raw, so they stayed English in every locale.
Mark them with msg() and render them through t(); add es and ru entries.
WHOT/BHOT and Ironbow keep their names. Russian Bloom is now «Свечение».

Subject: [PATCH 21/76] fix(i18n): translate the Street Level and Draw panels
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Both panels landed after the original string extraction, so they rendered
English in every locale. Mark their markup and runtime text (status, SINCE
stops, provider tooltips, coverage meta, viewer captions, draw hints and
colours), the layer-list names kept in PANEL_LABELS, and add 90 es and ru
entries. Street Level is «Уличные снимки» / «A pie de calle».

Subject: [PATCH 22/76] feat(i18n): find UI text that is not marked for
 translation

npm run i18n now also lists, and fails on, markup text and title /
aria-label / placeholder without data-i18n*, and string literals that reach
the page (textContent, innerHTML, setAttribute, toasts, label:/title:
properties and similar) without t(), tn() or msg(). Opt-outs say why where
the text lives: translate="no" and data-i18n-runtime in markup,
// i18n-ignore in code. src/tools/ is skipped: its text is for AI clients.

534 places are reported today; npm test does not run this part yet.

+## Text the check reports as unmarked
+
+`npm run i18n` also lists UI text that is not marked at all, and fails while there is any:
+
+- **Markup:** element text without `data-i18n`, and `title`, `aria-label` or `placeholder` without the matching `data-i18n-*`.
+- **Code:** string literals that reach the page without `t()`, `tn()` or `msg()`: assigned to `textContent`, `innerText`, `innerHTML`, `title`, `placeholder`; passed to `setAttribute('title' | 'aria-label' | 'aria-valuetext' | 'placeholder' | 'alt', …)`, `createTextNode`, `insertAdjacentHTML`, `showToast`, `toast`, `setHint`, `announce`; or kept in `label:`, `title:`, `tooltip:`, `placeholder:`, `hint:`, `ariaLabel:`, `caption:`, `subtitle:`, `kicker:`, `emptyText:` properties.
+
+Fix it by marking the text. When the text must stay as it is, say so where it lives:
+
+| Case                                                                        | How                                                                      |
+| --------------------------------------------------------------------------- | ------------------------------------------------------------------------ |
+| Codes, units, product names in markup (`0.9 dB`, `ADS-B · 1090`, `OpenSky`) | `translate="no"` on the element; it covers everything inside, as in HTML |
+| Markup whose text code sets through `t()` (a status that starts as `OFF`)   | `data-i18n-runtime` on the element                                       |
+| A literal in code that is not UI copy (a product name, sample data)         | `// i18n-ignore: <reason>` on the line or the line above                 |
+
+Icons (`aria-hidden="true"`, Material Symbols), comments, CSS values and lowercase identifiers are skipped automatically, and so is `src/tools/`, whose text is written for AI clients rather than the page.

Subject: [PATCH 23/76] feat(i18n): translate the whole interface

Mark every UI string the unmarked-text check reported (534) plus text it
cannot see (helpers, joined labels, runtime-built panels), and translate
the result to Spanish and Russian: 1,679 messages each.

- Kept on purpose, with the reason where the text lives: provider and
  product names, place and camera names, codes and units, dB values, the HUD
  terminal readouts, demo shot titles that saved projects look up by title,
  and text for AI tools and the voice model.
- Modules shared with the server or AI tools stay free of the i18n import
  (local msg); the wind reading and voice session stay English and are
  translated where the page shows them.
- npm test now runs the unmarked-text check.
- Fixes on the way: a duplicated radio privacy paragraph, the contact panel
  toggle saying Expand while open, the CSS filter mistaking &amp; for CSS.

Subject: [PATCH 24/76] fix(i18n): fix Russian layouts and the gaps the
 screenshot review found
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A review of the Russian UI screenshots found ~90 places where longer words
broke the layout or text was still English. Fixed so they hold for any
language, then shortened where a control is short by design.

- Layout: label columns that size to their text (weather and wind settings,
  Recent Imagery slots and opacity, style sliders, display panel), layer
  list names and icons, buttons that wrap instead of overflowing (CCTV,
  scenes, Bhote Koshi), voice header that always shows the cost, styled
  EN | ES | RU chips, voice error tray above the dock.
- t() context: t('CLEAR', { context: 'action' }) is «СБРОСИТЬ» while the sky
  stays «ЯСНО»; also used for radio categories, voice states and directions.
- Units and dates follow the locale through src/ui/unitLabels.js
  (formatQuantity: localized number, translated unit, non-breaking space):
  wind, pressure, cyclones, directions, CCTV, SDR gain, scene timing, flight
  tooltip, Recent Imagery dates and resolution.
- Newly translated: directions turn-by-turn steps (built from the maneuver;
  English matches the server word for word), HUD mode and summary, voice
  card states, radio categories on the globe, CCTV status, layer source
  lines, scene dialogs (Cancel, file pickers), Bhote Koshi statuses, titles,
  comparison dates and caveat, Recent Imagery notices. Stored data and text
  for AI tools stay English.
- es and ru: 1,885 messages each.

 - **No `t()` at module top level.** Keep the English in `msg()` and call `t()` when rendering.
 - **Numbers and dates** go through `formatNumber`, `formatDate` and `formatRelativeTime` from `src/i18n/index.js`, which follow the active language.
-- **Identical English means identical translation.** If two places need different words, make the English differ.
+- **Identical English means identical translation,** unless you give it a context: `t('CLEAR', { context: 'action' })` (a button) is its own catalog entry, `action|CLEAR`, while `t('CLEAR')` (the sky) stays separate. English output is the same.
 - **Text that should stay English** (a brand, a code, a unit symbol) is simply not wrapped.

Subject: [PATCH 25/76] fix(i18n): second screenshot review: remaining English,
 numbers and wraps
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

From the re-shot Russian screenshots:
- Translated: weather frame/imagery status errors, HUD summary provenance
  ("НЕДОСТУПНО: СУДА AIS ОНЛАЙН"), Bhote Koshi map labels, cockpit signal
  distances (КМ). The HUD summary fields are separated with " · " in every
  language, so the style name and view band no longer read as one phrase.
- Numbers follow the locale: cockpit altitude ("26 175"), precipitation.
- No breaks inside codes and dates: ADS-B and similar in layer rows,
  Sentinel-2, cyclone issue dates (word joiner; the UI font has no U+2011),
  no-break space after label colons in cyclone details.
- Layout: count lines under ALPR, short unavailable chip (context
  "status chip"), roomier draw segments, tighter CCTV calibration chips,
  two-line beat titles and media card titles, wrapping weather status.
- Wording: ru advisory is «сводка» (was «бюллетень»; "Advisory center" is
  «Центр циклона по сводке»), Street View is «Просмотр улиц», OPACITY
  «НЕПРОЗР.», synced «синхр.», Area «Зона»; the import dialog no longer says
  "this scene" for several scenes. Glossary updated.

Subject: [PATCH 28/76] fix(i18n): restore English output changed by the i18n
 foundation

A side-by-side English comparison with main found text the branch changed:
- Layer list names: #601 let its own catalog names win over the panel's
  English names, so "Live Vessels" read "Live AIS Vessels", "Bike Share"
  "Bikeshare", "Cameras" "CCTV", "Data Centers" "Datacenters", "Active Fires"
  "FIRMS Active Fires". The panel names win again.
- HUD feed-state suffix is "UNAVAILABLE LIVE AIS VESSELS" again (Russian keeps
  its colon); the mission panel aria-label is "Selected Space Mission" again;
  scene shot timing is "4.0s + 0.9s" again.

Subject: [PATCH 29/76] fix(i18n): keep English pixel-identical and stored data
 English

From the English-parity and breakage review against main:
- English wording back to main: "Configured Source", the "SHARED SUBJECT"
  fallback, CCTV calibration "RANGE 120m".
- Voice header and CCTV calibration chip/select tweaks for long labels now
  apply to non-English only (html:not([lang='en'])); English matches main.
  The scene select font change is scoped the same way.
- New scenes and shots store their default title in English ("Scene 3",
  "Shot 2") and translate it when shown, so a title captured in one language
  does not leak into projects, storage or shared JSON.
- Choosing a language with storage blocked keeps it in ?lang instead of
  silently doing nothing.
- One picked import file shows its name again.
- qa-l9-matrix reads the voice state from data-status, not the label.

Subject: [PATCH 30/76] fix(i18n): toast, boot labels and AI tool text found in
 review

- The Space Missions cancellation failure toast read "[object Object]" in
  every language: the options object was passed as the message. The English
  message is the second argument again, the translation the third.
- Header text is translated before panel chrome builds its collapse labels,
  so the dock and display toggles no longer read "Expand VISUAL PRESETS" in
  another language.
- The voice "show data layers" result keeps the English layer name
  (row data-layer-name), not the translated row text.
- The Google 3D unavailable reason is translated in full.

Subject: [PATCH 31/76] fix(i18n): keep values the AI tools read in English

- Satellite class in analyst records and voice payloads stays English
  ("STATION", "COMMS"), so voice filters on the class work in every
  language; cards and the legend still show the translated label.
- Layer source names (OSM routing, ALPR sources) stay English in layer
  state; the layer row translates them.
- New translateKnown(): catalog text when there is an entry, the given text
  otherwise, with no warning. The layer row uses it for loading labels and
  errors, Recent Imagery for its notices.
- Mark the remaining Recent Imagery and wind messages.

Subject: [PATCH 34/76] fix(i18n): Street Level errors in the UI language; hint
 row wraps

The Street Level error line and its toasts showed provider errors as
thrown (Google's key-rejected message stayed English). They go through
translateKnown now. In a translation the coverage hint no longer shrinks
to a narrow column beside OPEN GOOGLE STREET VIEW: the button takes its
own line when both do not fit. English layout is unchanged.

Subject: [PATCH 35/76] fix(i18n): Spanish review fixes; report translations
 left in English
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A screenshot review of the Spanish UI found:

- Text left in English. Catalog entries copied from English (Bloom,
  Cyber, Pin, NEWS, SITE, ON/OFF, RANGE, PITCH, HGT…) and the radio
  music genres, which never went through t(). The genres are translated
  in es and ru now.
- Wording: gender agreement, calques of the English, hints that name
  buttons that do not exist, and one concept worded two ways.
- Layout: the DESACTIVADO pill squeezed layer names until words broke
  mid-word; the scene and camera selects showed one word; a collapsed
  rail title pushed its button out of the card; the image slot line and
  a comparison readout were cut or split.

The layout fixes are scoped to languages other than English, so English
stays pixel-identical. Visual-style slider values now use the locale's
decimal separator (0,85).

npm run i18n now reports a translation that is identical to the
English, unless src/i18n/same-as-english.json lists it for that language
(codes, product names, words spelled the same).

Subject: [PATCH 36/76] fix(i18n): Google controls, vessel units and counts
 follow the UI language

Screens that only open with provider keys showed a few gaps:

- Google Street View's own controls (Map Data, Terms, Report a problem)
  and its addresses were always English: the Maps script now loads with
  the UI language. English adds no parameter, as before.
- The selected-vessel HUD line kept KT and DEG after translated labels.
- Layer counts used a decimal point (12.0K); other languages use their
  own separator (12,0K).
- A collapsed rail title was cut with an ellipsis in Russian; tighter
  tracking fits it whole. English is unchanged.

Subject: [PATCH 37/76] fix(i18n): Contacts panel text and distances in the UI
 language

The Contacts panel builds its markup in a variable before innerHTML, so
the unmarked-text check missed it: the window caption, "Named areas", the
"at least" count and each cohort's reason stayed English, and distances
read "4.6 km" in every language.

The reason stays English in the cohort summary, which the voice analyst
reads too; it now also carries its template, and the panel shows it in
the UI language. Distances and counts use the locale's number format
and unit.

Subject: [PATCH 38/76] feat: ship a web app manifest and home-screen icons

Adding the app to a phone home screen produced a blank tile: index.html
linked only an SVG favicon, and Safari ignores SVG for apple-touch-icon,
substituting a screenshot of the page. There was no manifest at all, so
Android had nothing to install against either.

Generate the rasters from public/logo.svg with sharp, which the repo
already carries. The output is committed so a plain `vite build` needs no
image toolchain; re-run scripts/generate-icons.mjs after changing the
logo. The logo's viewBox is wider than it is tall, so each icon centres
the mark on a square #0a0a0f canvas rather than stretching it, inset to
78% normally and 54% for the maskable variant to survive Android's
circular crop.

The SVG favicon stays as the browser tab icon.

 # Changelog
 
+- Ship a web app manifest and raster home-screen icons, so adding the app to a
+  phone home screen or installing it on desktop uses the God's Eye View mark
+  instead of a blank tile. The icons are generated from `public/logo.svg` by
+  `node scripts/generate-icons.mjs` and committed, so a plain `vite build` needs
+  no image toolchain. The existing SVG favicon still serves the browser tab.
+
 - GBFS v3 station names use English translations when available, then the first
   usable translation or short name. Empty or malformed names no longer appear as
   `[object Object]` or interrupt station loading; legacy string names remain

+## Web app install icons
+
+`public/manifest.webmanifest` declares the installable app: standalone display,
+`#0a0a0f` background and theme, and 192/512 icons plus a 512 maskable variant.
+`index.html` links the manifest, a 180px `apple-touch-icon` and a 32px PNG
+favicon; the existing SVG favicon still serves the browser tab. Safari ignores an
+SVG apple-touch-icon and substitutes a page screenshot, so the raster is what
+makes an installed icon appear at all.
+
+`node scripts/generate-icons.mjs` renders every raster from `public/logo.svg` and
+writes `public/icons/`. Output is committed, so building needs no image
+toolchain; re-run the script after changing the logo. Ordinary icons inset the
+mark to 78% of the canvas and the maskable variant to 54%, keeping it inside the
+circle Android may crop to. `src/tooling/webAppIcons.test.mjs` checks the links,
+the manifest fields and that each committed PNG is square at its declared size.
+
 ## Local build preview
 
 After `npm run build`, `npm run preview` serves the built app with the same data

Subject: [PATCH 39/76] fix: keep install assets inside a non-root base

Manifest start_url, scope and icon src resolve against the manifest URL,
so root-relative values sent an app served under a path prefix to the
domain root. Make them relative, and add a build test under
base: '/example/' that asserts every emitted link and manifest URL stays
inside the base. index.html is unchanged: Vite already rewrites its
links under base.

Subject: [PATCH 40/76] fix(i18n): Spanish keeps the HUD codes RANGE and SPD,
 as its glossary says

The review fixes had turned RANGE into DIST. and SPD into VEL.; the
Spanish glossary keeps HDG, BRG, CRS, FOV, DEST, SPD, RANGE and ALT in
English like cockpit avionics. The glossary now records the terms the
review settled: ACTIVO / INACTIVO, marcador, resplandor, Ciber,
NOTICIAS, INCL. / ALT.

Subject: [PATCH 41/76] fix(i18n): wording, dates and directions from the
 cross-model review
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Two other models reviewed the ru and es review PDFs. What held up:

- Directions: Russian reads "держитесь левее" at a fork and "займите
  левую полосу" for a lane, Spanish "toma el carril izquierdo". Forks and
  lanes get their own direction words; English is unchanged.
- Weather timestamps read "13.10 19:04 UTC" / "13/10 19:04 UTC" instead
  of "10-13", which read as a range. English keeps "10-13".
- Cockpit coordinates write the hemisphere out in Russian ("30,312° с.
  ш."): a lone «С» after a degree sign read as Celsius.
- A layer whose source joins several providers shows each name in the UI
  language ("Mapillary · Google Просмотр улиц").
- Vessel speed uses the locale's decimal separator.
- Layer names no longer hyphenate into two-letter pieces ("es-paciales").
- Catalog: wrong meanings (cyclone centre, STREAMING, credited source,
  "DE OÍDAS"), calques ("Пацифика", "Активная погода", "Прочитать вид",
  "referrer", worker), Russian "щёлкните по …", shorter Spanish labels
  that were cut (voice status, PREAJUSTES, search placeholder) and one
  term per concept.

Subject: [PATCH 42/76] fix(i18n): map cards and wind readout in the UI
 language; final review wording
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A final review of both PDFs found text the earlier checks missed:

- Map cards: fire confidence (high/nominal/low) and age (24h), vessel
  types (TOWING, TANKER) and installation classes (BASE, AIRFIELD) showed
  in English. They now go through the catalog; the data stays English.
- The wind readout kept "10-14 14:00 UTC" and "29.93°N 97.74°W"; it now
  uses the locale's date, decimal separator and hemisphere letters.
- Catalog: one term per concept (label/подпись, basemap/подложка,
  PROVIDER CONTROLS, HEARD, zoom in, REGIONAL NEWS), calques and broken
  grammar in the scene editor, provider settings and Bhote Koshi notes,
  and Spanish wording that read wrong ("restringidas por el proveedor",
  "Incluye … no se incluyen", "justo ahora", "Sal").

Subject: [PATCH 43/76] fix(i18n): selected fire card power and coordinates in
 the UI language
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The selected fire card read "4.9 MW" and "8.389°S 44.162°W" in every
language; it now uses the locale's decimal separator and hemisphere
words ("4,9 МВт", "8,389° ю. ш."). The data labels stay as they were.

Subject: [PATCH 44/76] test(street-level): settle coverage before reading the
 ON/OFF pill

The pill step read #sl-status straight after the credit wait. Tiles
requested while Cesium painted the credit can flip it back to LOADING,
which failed CI on PR #1038 (actual 'BUTTON:LOADING:true'). Wait for
coverage to settle and the pill to read ON before asserting.

Subject: [PATCH 45/76] i18n: fix review findings and polish ru/es strings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Fixes the 51 P0–P2 findings from the full review of the i18n branch and
the issues found while checking every new string on screen in ru and es.

- Translate errors and statuses that still reached ru/es in English:
  feed and tile errors, provider statuses, the ALPR chip, the traffic
  mode chip, voice plan step labels, fire feed values, receiver bands,
  scene save reasons and the Cesium attribution link.
- Show preset city names in the UI language (src/ui/placeNames.js);
  data and everything sent to the model stay English.
- Share layer names between the layer panel, HUD and voice card
  (src/ui/layerNames.js).
- Keep long ru/es strings whole: voice card error lines, analyst
  titles, the voice tier status, the Nepal evidence button, the ALPR
  retry chip. English layout is unchanged.
- Ask before a language switch drops unsaved work.
- Catalog fixes: glossary terms (пуск, пресет), gender agreement and
  consistent "peticiones" in es, fewer calques in both languages.
- Fix English text that was itself wrong (e.g. "Exit cockpit to fly to
  a weather", raw tool ids in voice plan steps).

Catalogs: es/ru 2535 messages each, complete.

+ * qa-scene-dialog-file-drop — the SHARE SCENE dialog's file control accepts a

+ *
+ * The dialog replaces the browser-drawn "Choose files / No file chosen" line
+ * with a translated one (src/ui/sceneSharing.js, fileChooser). The native
+ * input must stay the whole control underneath it: a shrunken 1 px input
+ * accepts drops only on its own pixel, so dragging a data-pack file onto the
+ * visible row selected nothing. This harness drops a file onto the centre of
+ * the visible row through CDP and expects `input.files` to hold it.
+ *
+ * Usage:
+ *   node scripts/qa-scene-dialog-file-drop.mjs
+ *
+ * Needs the repository's puppeteer (devDependencies). Exit status 0 when the
+ * drop selects the file, 1 otherwise.

Subject: [PATCH 46/76] i18n: wrap the ru/es push-to-talk hint; show city names
 in voice results
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- The help tray over the mic clipped the longer ru/es hint ("Hold Space
  to speak · tap Space to activate focused controls"); let it wrap in
  non-English locales. English layout is unchanged.
- The fly-to headline and the nearest-aircraft distance line now show a
  preset city in the interface language (Tokyo → Токио / Tokio); speech
  sent to the model stays English.

Subject: [PATCH 47/76] fix(i18n): Panoramax count line says nearest photo, not
 its photos

Panoramax's coverageLabel action is 'click a line for its nearest
photo' (like KartaView's) while it counts sequences, but the count-line
discriminator keyed only off the noun, so Panoramax fell through to the
default pair and promised 'its photos'. Discriminate on the action
first, then the noun, and add the sequences + nearest-photo pair
(KartaView keeps streets + nearest-photo; the default keeps sequences +
photos).

Subject: [PATCH 50/76] i18n: language picker in the bottom-right corner

Replaces the EN/ES/RU buttons in the Visual Presets dock with a picker
that scales to many languages: a globe button with the current code
next to the POWER UP chip, opening a list of languages named in their
own language with their codes, the current one first and checked. A
search field appears past 8 languages. Keyboard: arrows, Home/End,
Enter/Space, Esc, type-ahead; keys stay in the list while it is open.
Choosing a language still asks before dropping unsaved work, then
reloads. Phones get the globe alone and a full-width sheet; the layout
uses logical properties for right-to-left languages.

 Changing the English changes the key, so the old translation goes unused and the new text shows as missing. Add the translation to `src/i18n/locales/ru.json` (or ask a translator), prune, and run `npm test`, which runs the same check and fails until every language is complete.

Subject: [PATCH 51/76] feat(transit): add the TTC Toronto surface feed
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

TTC BusTime publishes keyless GTFS-Realtime VehiclePositions with real
coordinates for the surface network: ~1,180 buses and streetcars with
bearing and per-vehicle timestamps. Registering it is one registry row.

The subway is deliberately absent. BusTime covers surface vehicles only
and the subway publishes no positions, so Lines 1/2/4 are left out rather
than inferred from schedules — the same rule that keeps NYCT out.

Route numbers establish the mode: the three-digit 500-series is streetcar,
as are the four Blue Night routes on streetcar trackage. A leading 5 alone
would misclassify bus routes 50-59, so the rule is anchored and tested.

Licensing is the portal-wide Open Government Licence - Toronto; the CKAN
record for the BusTime NVAS dataset leaves its own licence field blank,
and the terms note says so rather than overstating the grant.

 - **NYC DOT Traffic Management Center cameras.** Off by default. NYC DOT's [developer data feeds page](https://www.nyc.gov/html/dot/html/about/datafeeds.shtml) asks developers who want the camera feed to contact `tmcdot@dot.nyc.gov` and sign a data-sharing agreement. This project does not hold one that covers downstream installations, so the pack loads only when an operator who holds their own agreement sets `CCTV_NYC_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to NYC DOT. The endpoint needs no key. The camera list is the public `webcams.nyctmc.org/api/cameras` catalog (~980 cameras across the five boroughs); frames are stills at `webcams.nyctmc.org/api/cameras/<uuid>/image`, synthesized from a validated UUID rather than taken from the payload, and only that host is registered. Cameras the feed reports as offline are dropped. The catalog publishes no camera facing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. Once enabled, the 250 cameras nearest the borough cores load; `CCTV_NYC_MAX_SOURCES` (8–400) changes the cap. Frames are fetched at request time and never stored or redistributed. NYC DOT asks every application that uses its data to carry its disclaimer; it is registered verbatim in the Data attribution popover.
 - **City of Toronto RESCU cameras.** Keyless. The camera list is the City's public `tmcearthcameras.json` on `opendata.toronto.ca` (dataset "Traffic Cameras", Transportation Services), served as JSONP and unwrapped with an anchored pattern. This is the municipal network the Ontario 511 pack does not carry: downtown arterials plus the Gardiner, DVP, Allen and Lake Shore. The list publishes no frame URL, so frame URLs are BUILT from the documented `CameraImages/loc####.jpg` convention and a strictly-digits camera number, pinning the frame proxy to the portal origin by construction; the list fetch refuses redirects and bounds the body it buffers. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing: the `D1`-`D4` fields are the directions of the *comparison* images (static reference stills captured in 2016 under a different path), not a bearing for the live pan-tilt-zoom frame, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. A camera that is temporarily out of service still answers 200 with a byte-identical "Image Unavailable" placeholder rather than an error (about 6% of the network at any moment), so such a camera reads as healthy; the frame it shows is the agency's, not a synthesized one. The licence requires the attribution statement above. Disable with `CCTV_TORONTO_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 seven 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.

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.
 - **Radio Browser.** `/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; schema-valid responses whose rows all fail the product's health policy do not count as successful queries. A usable partial cold catalog is explicitly `DEGRADED`, and malformed or empty successful payloads are rejected atomically. 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.
 - **TomTom Traffic.** Optional and BYOK: without `TOMTOM_API_KEY` the traffic layer runs its built-in simulation and no TomTom data (or attribution) appears. With a key, flow vector tiles are fetched through the server-side `/api/tomtom` proxy (120 s cache + a daily tile-budget governor — `TOMTOM_DAILY_TILE_BUDGET`, default 6,000 — sized so a 31-day month stays inside TomTom's 200K monthly free allowance; still a configurable application safety ceiling, not a guarantee; TomTom's [current pricing](https://docs.tomtom.com/pricing/) lists 200K free tile requests per month) and the "Traffic flow data © TomTom" credit is registered in the Data attribution popover the moment live mode activates. TomTom data is served live and cached only transiently (≤120 s TTL under `.gev-cache/`, gitignored) — it is not bundled or redistributed. One 23 KB point-in-time tile snapshot is committed as a decode-test fixture (`src/data/fixtures/`, © TomTom, never served to the app).
 - **Routing (OSRM / FOSSGIS).** `/api/route` proxies the public OSRM instances FOSSGIS e.V. runs for the OpenStreetMap community (car, bike, foot profiles). They are keyless and intended for fair, interactive use — the proxy rate-limits clients (60/min, 200/min total), caps route span and response size, caches each route for 10 minutes, and identifies itself in the User-Agent. Heavy or automated use must run its own OSRM. Routes are computed from OpenStreetMap data (ODbL); the Directions layer and voice routes never redistribute them. A route the router cannot find is reported as such; the Directions layer draws nothing in that case, and voice routes fall back to a clearly labeled straight line.

Subject: [PATCH 52/76] feat(transit): let a feed name its own modes, and call
 TTC trams streetcars
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A Toronto 501 and a Helsinki 1010 are both the `tram` mode. Only one of
them is called a tram by the people who ride it, and the detection label
is documented as "what a person standing at the stop would call it".

So the mode stays shared — same silhouette, same speed limits — and a
registry entry may carry `modeWords` naming the modes it runs. Everything
without an override falls through to the shared table, so this renames one
word for one operator and nothing else.

Threading the feed to the detection metric needed a resolver in queries.js,
since the cached-contact path has only the entry. It answers from live feeds
first, so a feed disabled mid-session stops supplying vocabulary.

Subject: [PATCH 53/76] feat(transit): add MiWay, Hamilton HSR and Durham
 Region Transit
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Three keyless GTFS-Realtime feeds around Toronto, each verified live: all
vehicles carry real coordinates, and each is polled only near its own
region rather than across the Golden Horseshoe.

The licences differ in ways the registry now records rather than flattens:
Hamilton PRESCRIBES its attribution wording, so the credit is that exact
sentence; Durham makes credit optional and its catalogued licence PDF is
dead after a site relaunch, so licenseUrl points at the live page where the
v.1.0 text was actually read; Mississauga's licence is revocable and asks
that the terms travel with the data, so licenseUrl is the terms themselves.

All three are bus-only and set no route hint, so their modes default rather
than resolve. Durham publishes no bearing on any vehicle — heading comes
from observed movement, as with any feed that omits it.

GO Transit / Metrolinx stays out: its feed requires an API key.

 - **NYC DOT Traffic Management Center cameras.** Off by default. NYC DOT's [developer data feeds page](https://www.nyc.gov/html/dot/html/about/datafeeds.shtml) asks developers who want the camera feed to contact `tmcdot@dot.nyc.gov` and sign a data-sharing agreement. This project does not hold one that covers downstream installations, so the pack loads only when an operator who holds their own agreement sets `CCTV_NYC_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to NYC DOT. The endpoint needs no key. The camera list is the public `webcams.nyctmc.org/api/cameras` catalog (~980 cameras across the five boroughs); frames are stills at `webcams.nyctmc.org/api/cameras/<uuid>/image`, synthesized from a validated UUID rather than taken from the payload, and only that host is registered. Cameras the feed reports as offline are dropped. The catalog publishes no camera facing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. Once enabled, the 250 cameras nearest the borough cores load; `CCTV_NYC_MAX_SOURCES` (8–400) changes the cap. Frames are fetched at request time and never stored or redistributed. NYC DOT asks every application that uses its data to carry its disclaimer; it is registered verbatim in the Data attribution popover.
 - **City of Toronto RESCU cameras.** Keyless. The camera list is the City's public `tmcearthcameras.json` on `opendata.toronto.ca` (dataset "Traffic Cameras", Transportation Services), served as JSONP and unwrapped with an anchored pattern. This is the municipal network the Ontario 511 pack does not carry: downtown arterials plus the Gardiner, DVP, Allen and Lake Shore. The list publishes no frame URL, so frame URLs are BUILT from the documented `CameraImages/loc####.jpg` convention and a strictly-digits camera number, pinning the frame proxy to the portal origin by construction; the list fetch refuses redirects and bounds the body it buffers. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing: the `D1`-`D4` fields are the directions of the *comparison* images (static reference stills captured in 2016 under a different path), not a bearing for the live pan-tilt-zoom frame, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. A camera that is temporarily out of service still answers 200 with a byte-identical "Image Unavailable" placeholder rather than an error (about 6% of the network at any moment), so such a camera reads as healthy; the frame it shows is the agency's, not a synthesized one. The licence requires the attribution statement above. Disable with `CCTV_TORONTO_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.

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. GO Transit / Metrolinx is deliberately absent: its realtime feed requires an API key, which the keyless admission rule excludes.
 - **Radio Browser.** `/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; schema-valid responses whose rows all fail the product's health policy do not count as successful queries. A usable partial cold catalog is explicitly `DEGRADED`, and malformed or empty successful payloads are rejected atomically. 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.
 - **TomTom Traffic.** Optional and BYOK: without `TOMTOM_API_KEY` the traffic layer runs its built-in simulation and no TomTom data (or attribution) appears. With a key, flow vector tiles are fetched through the server-side `/api/tomtom` proxy (120 s cache + a daily tile-budget governor — `TOMTOM_DAILY_TILE_BUDGET`, default 6,000 — sized so a 31-day month stays inside TomTom's 200K monthly free allowance; still a configurable application safety ceiling, not a guarantee; TomTom's [current pricing](https://docs.tomtom.com/pricing/) lists 200K free tile requests per month) and the "Traffic flow data © TomTom" credit is registered in the Data attribution popover the moment live mode activates. TomTom data is served live and cached only transiently (≤120 s TTL under `.gev-cache/`, gitignored) — it is not bundled or redistributed. One 23 KB point-in-time tile snapshot is committed as a decode-test fixture (`src/data/fixtures/`, © TomTom, never served to the app).
 - **Routing (OSRM / FOSSGIS).** `/api/route` proxies the public OSRM instances FOSSGIS e.V. runs for the OpenStreetMap community (car, bike, foot profiles). They are keyless and intended for fair, interactive use — the proxy rate-limits clients (60/min, 200/min total), caps route span and response size, caches each route for 10 minutes, and identifies itself in the User-Agent. Heavy or automated use must run its own OSRM. Routes are computed from OpenStreetMap data (ODbL); the Directions layer and voice routes never redistribute them. A route the router cannot find is reported as such; the Directions layer draws nothing in that case, and voice routes fall back to a clearly labeled straight line.

Subject: [PATCH 54/76] feat(transit): add Guelph and Kingston, register Barrie
 off
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Guelph's feed publishes the internal database key of a route (`2991`)
where the rider sees the number on the bus (`1`), which would have put
"Route 2991" on the label a person reads. So a feed may now carry its own
`routeLabel`, the same way it may carry its own `modeWords`. Guelph's table
is its 33 routes, taken from the City's own published GTFS; an id missing
from it renders unchanged, because a raw id you can compare against the bus
beats a blank. Every other feed is identity and carries no table.

Kingston is catalogued by the City against this exact URL. Its licence PDF
link is pinned to the canonical location rather than the legacy path that
currently redirects there — Durham's entry records what happens when such a
redirect is eventually dropped.

Barrie ships REGISTERED AND OFF. The City offers its licence for acceptance
behind a click-through gate, and nobody on this project has accepted it.
Whether to accept is a person's decision, not an assumption a poller should
make, so the feed is visible, documented, and one line from enabled.

 - **NYC DOT Traffic Management Center cameras.** Off by default. NYC DOT's [developer data feeds page](https://www.nyc.gov/html/dot/html/about/datafeeds.shtml) asks developers who want the camera feed to contact `tmcdot@dot.nyc.gov` and sign a data-sharing agreement. This project does not hold one that covers downstream installations, so the pack loads only when an operator who holds their own agreement sets `CCTV_NYC_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to NYC DOT. The endpoint needs no key. The camera list is the public `webcams.nyctmc.org/api/cameras` catalog (~980 cameras across the five boroughs); frames are stills at `webcams.nyctmc.org/api/cameras/<uuid>/image`, synthesized from a validated UUID rather than taken from the payload, and only that host is registered. Cameras the feed reports as offline are dropped. The catalog publishes no camera facing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. Once enabled, the 250 cameras nearest the borough cores load; `CCTV_NYC_MAX_SOURCES` (8–400) changes the cap. Frames are fetched at request time and never stored or redistributed. NYC DOT asks every application that uses its data to carry its disclaimer; it is registered verbatim in the Data attribution popover.
 - **City of Toronto RESCU cameras.** Keyless. The camera list is the City's public `tmcearthcameras.json` on `opendata.toronto.ca` (dataset "Traffic Cameras", Transportation Services), served as JSONP and unwrapped with an anchored pattern. This is the municipal network the Ontario 511 pack does not carry: downtown arterials plus the Gardiner, DVP, Allen and Lake Shore. The list publishes no frame URL, so frame URLs are BUILT from the documented `CameraImages/loc####.jpg` convention and a strictly-digits camera number, pinning the frame proxy to the portal origin by construction; the list fetch refuses redirects and bounds the body it buffers. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing: the `D1`-`D4` fields are the directions of the *comparison* images (static reference stills captured in 2016 under a different path), not a bearing for the live pan-tilt-zoom frame, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. A camera that is temporarily out of service still answers 200 with a byte-identical "Image Unavailable" placeholder rather than an error (about 6% of the network at any moment), so such a camera reads as healthy; the frame it shows is the agency's, not a synthesized one. The licence requires the attribution statement above. Disable with `CCTV_TORONTO_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 eleven 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. GO Transit / Metrolinx is deliberately absent: its realtime feed requires an API key, which the keyless admission rule excludes.

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. Guelph is the one feed whose route ids are internal keys rather than the number on the bus, so its entry carries a route-number table taken from the City’s own published GTFS; any id missing from that table renders unchanged rather than blank. 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). 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.
 - **Radio Browser.** `/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; schema-valid responses whose rows all fail the product's health policy do not count as successful queries. A usable partial cold catalog is explicitly `DEGRADED`, and malformed or empty successful payloads are rejected atomically. 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.
 - **TomTom Traffic.** Optional and BYOK: without `TOMTOM_API_KEY` the traffic layer runs its built-in simulation and no TomTom data (or attribution) appears. With a key, flow vector tiles are fetched through the server-side `/api/tomtom` proxy (120 s cache + a daily tile-budget governor — `TOMTOM_DAILY_TILE_BUDGET`, default 6,000 — sized so a 31-day month stays inside TomTom's 200K monthly free allowance; still a configurable application safety ceiling, not a guarantee; TomTom's [current pricing](https://docs.tomtom.com/pricing/) lists 200K free tile requests per month) and the "Traffic flow data © TomTom" credit is registered in the Data attribution popover the moment live mode activates. TomTom data is served live and cached only transiently (≤120 s TTL under `.gev-cache/`, gitignored) — it is not bundled or redistributed. One 23 KB point-in-time tile snapshot is committed as a decode-test fixture (`src/data/fixtures/`, © TomTom, never served to the app).
 - **Routing (OSRM / FOSSGIS).** `/api/route` proxies the public OSRM instances FOSSGIS e.V. runs for the OpenStreetMap community (car, bike, foot profiles). They are keyless and intended for fair, interactive use — the proxy rate-limits clients (60/min, 200/min total), caps route span and response size, caches each route for 10 minutes, and identifies itself in the User-Agent. Heavy or automated use must run its own OSRM. Routes are computed from OpenStreetMap data (ODbL); the Directions layer and voice routes never redistribute them. A route the router cannot find is reported as such; the Directions layer draws nothing in that case, and voice routes fall back to a clearly labeled straight line.

Subject: [PATCH 55/76] feat(transit): register YRT/Viva off, named by Viva
 colour
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

York Region's feed is first-party infrastructure under an open licence that
permits commercial use and does not even require attribution. It is the one
feed that fills the gap north of Toronto, and it is switched off anyway.

The operator asks that its licence be accepted through a form collecting a
name, company, phone and email. No credential is issued and nothing gates
the endpoint — the licence body says use is itself acceptance — but a form
asking for contact details is close enough to the registration this registry
refuses that a person should decide it, not a poller. Barrie is off for the
same reason. Both are one line from on.

Viva route ids get labels: YRT publishes `601` where every station sign says
Viva Blue. The numeric local routes already read correctly and carry no
entry, so the table is six lines, not 125.

No vehicle in this feed carries a bearing; heading comes from observed
movement, as with Durham.

 - **NYC DOT Traffic Management Center cameras.** Off by default. NYC DOT's [developer data feeds page](https://www.nyc.gov/html/dot/html/about/datafeeds.shtml) asks developers who want the camera feed to contact `tmcdot@dot.nyc.gov` and sign a data-sharing agreement. This project does not hold one that covers downstream installations, so the pack loads only when an operator who holds their own agreement sets `CCTV_NYC_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to NYC DOT. The endpoint needs no key. The camera list is the public `webcams.nyctmc.org/api/cameras` catalog (~980 cameras across the five boroughs); frames are stills at `webcams.nyctmc.org/api/cameras/<uuid>/image`, synthesized from a validated UUID rather than taken from the payload, and only that host is registered. Cameras the feed reports as offline are dropped. The catalog publishes no camera facing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. Once enabled, the 250 cameras nearest the borough cores load; `CCTV_NYC_MAX_SOURCES` (8–400) changes the cap. Frames are fetched at request time and never stored or redistributed. NYC DOT asks every application that uses its data to carry its disclaimer; it is registered verbatim in the Data attribution popover.
 - **City of Toronto RESCU cameras.** Keyless. The camera list is the City's public `tmcearthcameras.json` on `opendata.toronto.ca` (dataset "Traffic Cameras", Transportation Services), served as JSONP and unwrapped with an anchored pattern. This is the municipal network the Ontario 511 pack does not carry: downtown arterials plus the Gardiner, DVP, Allen and Lake Shore. The list publishes no frame URL, so frame URLs are BUILT from the documented `CameraImages/loc####.jpg` convention and a strictly-digits camera number, pinning the frame proxy to the portal origin by construction; the list fetch refuses redirects and bounds the body it buffers. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing: the `D1`-`D4` fields are the directions of the *comparison* images (static reference stills captured in 2016 under a different path), not a bearing for the live pan-tilt-zoom frame, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. A camera that is temporarily out of service still answers 200 with a byte-identical "Image Unavailable" placeholder rather than an error (about 6% of the network at any moment), so such a camera reads as healthy; the frame it shows is the agency's, not a synthesized one. The licence requires the attribution statement above. Disable with `CCTV_TORONTO_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. Thirteen of the fourteen registered regions are live-enabled (Barrie is registered and deliberately off); 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. Guelph is the one feed whose route ids are internal keys rather than the number on the bus, so its entry carries a route-number table taken from the City’s own published GTFS; any id missing from that table renders unchanged rather than blank. 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). 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.

Two feeds are registered and switched off rather than absent: Barrie and YRT/Viva both ask that their licence be accepted through a form before the data is taken, and that is a person’s decision rather than an assumption a poller should make. 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.
 - **Radio Browser.** `/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; schema-valid responses whose rows all fail the product's health policy do not count as successful queries. A usable partial cold catalog is explicitly `DEGRADED`, and malformed or empty successful payloads are rejected atomically. 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.
 - **TomTom Traffic.** Optional and BYOK: without `TOMTOM_API_KEY` the traffic layer runs its built-in simulation and no TomTom data (or attribution) appears. With a key, flow vector tiles are fetched through the server-side `/api/tomtom` proxy (120 s cache + a daily tile-budget governor — `TOMTOM_DAILY_TILE_BUDGET`, default 6,000 — sized so a 31-day month stays inside TomTom's 200K monthly free allowance; still a configurable application safety ceiling, not a guarantee; TomTom's [current pricing](https://docs.tomtom.com/pricing/) lists 200K free tile requests per month) and the "Traffic flow data © TomTom" credit is registered in the Data attribution popover the moment live mode activates. TomTom data is served live and cached only transiently (≤120 s TTL under `.gev-cache/`, gitignored) — it is not bundled or redistributed. One 23 KB point-in-time tile snapshot is committed as a decode-test fixture (`src/data/fixtures/`, © TomTom, never served to the app).
 - **Routing (OSRM / FOSSGIS).** `/api/route` proxies the public OSRM instances FOSSGIS e.V. runs for the OpenStreetMap community (car, bike, foot profiles). They are keyless and intended for fair, interactive use — the proxy rate-limits clients (60/min, 200/min total), caps route span and response size, caches each route for 10 minutes, and identifies itself in the User-Agent. Heavy or automated use must run its own OSRM. Routes are computed from OpenStreetMap data (ODbL); the Directions layer and voice routes never redistribute them. A route the router cannot find is reported as such; the Directions layer draws nothing in that case, and voice routes fall back to a clearly labeled straight line.

Subject: [PATCH 56/76] feat(transit): add Burlington, switch Barrie and YRT on
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Burlington's route ids are internal keys with a trap in them: `351` is
route 1 while `3510` is route 10, so no prefix trim is correct and the
table is a real join against the City's own published GTFS. Its licence is
the same 2011 municipal template as Mississauga — revocable, and the terms
must travel with the data, so licenseUrl is the terms document itself.
Plain http:// has no listener at all, so https is mandatory, not preferred.

Barrie and YRT ship on. Both operators invite acceptance of their licence
through a form, and both licences also state that use is itself acceptance
("By using Barrie Transit Data, you agree to be bound by these terms";
"Your Use of Information indicates Your acceptance"). This deployment
relies on that clause, and both entries record it so the reasoning does not
have to be re-derived.

Nine Ontario feeds now, all verified live against their upstreams.

 - **NYC DOT Traffic Management Center cameras.** Off by default. NYC DOT's [developer data feeds page](https://www.nyc.gov/html/dot/html/about/datafeeds.shtml) asks developers who want the camera feed to contact `tmcdot@dot.nyc.gov` and sign a data-sharing agreement. This project does not hold one that covers downstream installations, so the pack loads only when an operator who holds their own agreement sets `CCTV_NYC_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to NYC DOT. The endpoint needs no key. The camera list is the public `webcams.nyctmc.org/api/cameras` catalog (~980 cameras across the five boroughs); frames are stills at `webcams.nyctmc.org/api/cameras/<uuid>/image`, synthesized from a validated UUID rather than taken from the payload, and only that host is registered. Cameras the feed reports as offline are dropped. The catalog publishes no camera facing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. Once enabled, the 250 cameras nearest the borough cores load; `CCTV_NYC_MAX_SOURCES` (8–400) changes the cap. Frames are fetched at request time and never stored or redistributed. NYC DOT asks every application that uses its data to carry its disclaimer; it is registered verbatim in the Data attribution popover.
 - **City of Toronto RESCU cameras.** Keyless. The camera list is the City's public `tmcearthcameras.json` on `opendata.toronto.ca` (dataset "Traffic Cameras", Transportation Services), served as JSONP and unwrapped with an anchored pattern. This is the municipal network the Ontario 511 pack does not carry: downtown arterials plus the Gardiner, DVP, Allen and Lake Shore. The list publishes no frame URL, so frame URLs are BUILT from the documented `CameraImages/loc####.jpg` convention and a strictly-digits camera number, pinning the frame proxy to the portal origin by construction; the list fetch refuses redirects and bounds the body it buffers. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing: the `D1`-`D4` fields are the directions of the *comparison* images (static reference stills captured in 2016 under a different path), not a bearing for the live pan-tilt-zoom frame, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. A camera that is temporarily out of service still answers 200 with a byte-identical "Image Unavailable" placeholder rather than an error (about 6% of the network at any moment), so such a camera reads as healthy; the frame it shows is the agency's, not a synthesized one. The licence requires the attribution statement above. Disable with `CCTV_TORONTO_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. Thirteen of the fifteen registered regions are live-enabled; Barrie and YRT/Viva are registered and deliberately off; 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. Guelph is the one feed whose route ids are internal keys rather than the number on the bus, so its entry carries a route-number table taken from the City’s own published GTFS; any id missing from that table renders unchanged rather than blank. 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). Two feeds are registered and switched off rather than absent: Barrie and YRT/Viva both ask that their licence be accepted through a form before the data is taken, and that is a person’s decision rather than an assumption a poller should make. 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.

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. 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.
 - **Radio Browser.** `/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; schema-valid responses whose rows all fail the product's health policy do not count as successful queries. A usable partial cold catalog is explicitly `DEGRADED`, and malformed or empty successful payloads are rejected atomically. 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.
 - **TomTom Traffic.** Optional and BYOK: without `TOMTOM_API_KEY` the traffic layer runs its built-in simulation and no TomTom data (or attribution) appears. With a key, flow vector tiles are fetched through the server-side `/api/tomtom` proxy (120 s cache + a daily tile-budget governor — `TOMTOM_DAILY_TILE_BUDGET`, default 6,000 — sized so a 31-day month stays inside TomTom's 200K monthly free allowance; still a configurable application safety ceiling, not a guarantee; TomTom's [current pricing](https://docs.tomtom.com/pricing/) lists 200K free tile requests per month) and the "Traffic flow data © TomTom" credit is registered in the Data attribution popover the moment live mode activates. TomTom data is served live and cached only transiently (≤120 s TTL under `.gev-cache/`, gitignored) — it is not bundled or redistributed. One 23 KB point-in-time tile snapshot is committed as a decode-test fixture (`src/data/fixtures/`, © TomTom, never served to the app).
 - **Routing (OSRM / FOSSGIS).** `/api/route` proxies the public OSRM instances FOSSGIS e.V. runs for the OpenStreetMap community (car, bike, foot profiles). They are keyless and intended for fair, interactive use — the proxy rate-limits clients (60/min, 200/min total), caps route span and response size, caches each route for 10 minutes, and identifies itself in the User-Agent. Heavy or automated use must run its own OSRM. Routes are computed from OpenStreetMap data (ODbL); the Directions layer and voice routes never redistribute them. A route the router cannot find is reported as such; the Directions layer draws nothing in that case, and voice routes fall back to a clearly labeled straight line.

Subject: [PATCH 57/76] feat(transit): name YRT's local branch routes
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

YRT encodes a branch as a two-digit suffix on the base route id. The Viva
table already depended on that scheme — `60102` is Viva Blue's B branch —
but local routes were passed through whole, on the reasoning that a YRT
route id is already the number on the bus. For a plain route it is. For a
branch it is not: a rider watching route 83's B-branch bus saw "8301".

A 15:41 EDT sample of the live feed found four branch ids in service.
Three are published in York Region's GTFS `routes.txt` and are named here
from it, unpadded to match the local routes beside them (the file says
`083A`; the registry has always preferred `105` to `005`):

    10702 -> 107B   KEELE
    8301  -> 83A    TRENCH
    9002  -> 90B    LESLIE

The fourth, `9101`, runs in the realtime feed but appears nowhere in
`routes.txt`. The pattern all but spells "91A" and that is precisely why
it is absent: the registry translates published names, it does not infer
them. It stays opaque until York Region publishes it.

Renamed YRT_VIVA_ROUTE_NAMES to YRT_ROUTE_NAMES, since the table is no
longer only about Viva.

Subject: [PATCH 59/76] feat(transit): name Hamilton's routes, which ship as
 internal keys
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Not one of HSR's 80 route ids equals the number on the bus. Hamilton was
registered without a routeLabel, so every vehicle in the city read as
"Route 5783" where a rider would say 5 DELAWARE — 228 of them in an
afternoon sample. The mechanism to fix it already existed and simply was
never pointed at this feed.

Two details the table cannot skip:

Hamilton runs two generations of route id at once. `5688` and `5780` are
both the 2 BARTON, and both arrive in the live feed, so both are listed.
That is why 80 ids collapse to 46 distinct routes.

The seasonal and event shuttles publish a name where the local routes
publish a number — TC230, PEACH, ROCKTON. Those are already what a rider
would say, so they survive as published rather than being forced into a
number they do not have. Numbers are unpadded to match the rest of the
registry: routes.txt says `02`, a rider says 2.

Ids and names are from the City's own published GTFS routes.txt, which
sits under the same open-data licence as the realtime feed. Checked
against the live feed: all 30 route ids in service translate, none fall
through.

Subject: [PATCH 60/76] docs: record Hamilton's route table and the feeds left
 out

Two gaps. The Hamilton entry never said its route ids are internal keys,
which the Guelph, Burlington and YRT entries all say of theirs; the
route-table sentence in the transit notes named those three and not
Hamilton, though it now carries the largest table of the four. Both were
stale the moment Hamilton got a table.

The exclusions were half-recorded: GO Transit and Grand River had their
reasons written down, but Ottawa, London, Thunder Bay and the static-only
majority did not, so a later reader would have re-investigated feeds that
were already surveyed and rejected. All of them are now named with the
rule each one falls to, and the survey is stated as complete against the
Mobility Database's Ontario catalogue.

Also records that a route label is never invented, which is why YRT's
unpublished 9101 renders as the feed sends it.

 - **NYC DOT Traffic Management Center cameras.** Off by default. NYC DOT's [developer data feeds page](https://www.nyc.gov/html/dot/html/about/datafeeds.shtml) asks developers who want the camera feed to contact `tmcdot@dot.nyc.gov` and sign a data-sharing agreement. This project does not hold one that covers downstream installations, so the pack loads only when an operator who holds their own agreement sets `CCTV_NYC_ENABLED=1`; with the flag unset, empty or any other value, the server makes no request to NYC DOT. The endpoint needs no key. The camera list is the public `webcams.nyctmc.org/api/cameras` catalog (~980 cameras across the five boroughs); frames are stills at `webcams.nyctmc.org/api/cameras/<uuid>/image`, synthesized from a validated UUID rather than taken from the payload, and only that host is registered. Cameras the feed reports as offline are dropped. The catalog publishes no camera facing, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. Once enabled, the 250 cameras nearest the borough cores load; `CCTV_NYC_MAX_SOURCES` (8–400) changes the cap. Frames are fetched at request time and never stored or redistributed. NYC DOT asks every application that uses its data to carry its disclaimer; it is registered verbatim in the Data attribution popover.
 - **City of Toronto RESCU cameras.** Keyless. The camera list is the City's public `tmcearthcameras.json` on `opendata.toronto.ca` (dataset "Traffic Cameras", Transportation Services), served as JSONP and unwrapped with an anchored pattern. This is the municipal network the Ontario 511 pack does not carry: downtown arterials plus the Gardiner, DVP, Allen and Lake Shore. The list publishes no frame URL, so frame URLs are BUILT from the documented `CameraImages/loc####.jpg` convention and a strictly-digits camera number, pinning the frame proxy to the portal origin by construction; the list fetch refuses redirects and bounds the body it buffers. Frames are fetched at request time and never stored or redistributed. The dataset publishes no camera facing: the `D1`-`D4` fields are the directions of the *comparison* images (static reference stills captured in 2016 under a different path), not a bearing for the live pan-tilt-zoom frame, so headings use the shared id-hash fallback at low confidence and are corrected with the in-app calibration gizmo. A camera that is temporarily out of service still answers 200 with a byte-identical "Image Unavailable" placeholder rather than an error (about 6% of the network at any moment), so such a camera reads as healthy; the frame it shows is the agency's, not a synthesized one. The licence requires the attribution statement above. Disable with `CCTV_TORONTO_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. 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. 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.

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 Browser.** `/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; schema-valid responses whose rows all fail the product's health policy do not count as successful queries. A usable partial cold catalog is explicitly `DEGRADED`, and malformed or empty successful payloads are rejected atomically. 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.
 - **TomTom Traffic.** Optional and BYOK: without `TOMTOM_API_KEY` the traffic layer runs its built-in simulation and no TomTom data (or attribution) appears. With a key, flow vector tiles are fetched through the server-side `/api/tomtom` proxy (120 s cache + a daily tile-budget governor — `TOMTOM_DAILY_TILE_BUDGET`, default 6,000 — sized so a 31-day month stays inside TomTom's 200K monthly free allowance; still a configurable application safety ceiling, not a guarantee; TomTom's [current pricing](https://docs.tomtom.com/pricing/) lists 200K free tile requests per month) and the "Traffic flow data © TomTom" credit is registered in the Data attribution popover the moment live mode activates. TomTom data is served live and cached only transiently (≤120 s TTL under `.gev-cache/`, gitignored) — it is not bundled or redistributed. One 23 KB point-in-time tile snapshot is committed as a decode-test fixture (`src/data/fixtures/`, © TomTom, never served to the app).
 - **Routing (OSRM / FOSSGIS).** `/api/route` proxies the public OSRM instances FOSSGIS e.V. runs for the OpenStreetMap community (car, bike, foot profiles). They are keyless and intended for fair, interactive use — the proxy rate-limits clients (60/min, 200/min total), caps route span and response size, caches each route for 10 minutes, and identifies itself in the User-Agent. Heavy or automated use must run its own OSRM. Routes are computed from OpenStreetMap data (ODbL); the Directions layer and voice routes never redistribute them. A route the router cannot find is reported as such; the Directions layer draws nothing in that case, and voice routes fall back to a clearly labeled straight line.

Subject: [PATCH 61/76] docs: list the Ontario regions in the README feature
 table

The Transit row names the regions a reader can expect to see vehicles in,
and still stopped at South East Queensland after nine Ontario feeds were
added. Someone scanning the table for Toronto would have concluded the
layer does not cover it.

Toronto carries the subway caveat here too: the row would otherwise
promise metros in a city whose metro publishes no positions.

Subject: [PATCH 64/76] Tighten datasheet model matching and keep given fields
 of view

Codec, product and resolution words never identify a model; generation suffixes such as Mk II no longer fall back to the base model; a mismatched manufacturer never matches, and brand-only numeric names need the brand. The datasheet FOV only fills when the source and seed give none and the pose is not curated, and DATASHEET is shown only while no calibration offset applies. Adds the CC0 extract to DATA_SOURCES.

Subject: [PATCH 65/76] Take TTC vehicle mode from the fleet number before the
 route

Replacement buses on 5xx streetcar routes were drawn as streetcars, and
Flexity streetcars reporting no route were drawn as buses. A feed can now
supply vehicleMode(id); TTC maps 4400-4699 to streetcars and every other
fleet number to buses, falling back to the route otherwise.

Subject: [PATCH 66/76] feat(bikeshare): add Barcelona's Bicing and AMBici

- Bicing (543 stations, PBSC) and AMBici (237 e-bike stations across the
  metropolitan area, nextbike) join the GBFS registry from the operators'
  keyless GBFS 2.3 feeds, both listed in MobilityData's systems catalogue.
- gbfs.nextbike.net joins the proxy allowlist as an exact host.
- Credits, DATA_SOURCES, CURRENT-STATE and CHANGELOG updated; a test pins
  each system's proxy reachability and the range check for its outermost
  stations.

Subject: [PATCH 67/76] test(bikeshare): pin the Barcelona load radii to their
 outermost stations

The map range check floors every radius at 100 km, so the station test
passed with any loadRadiusKm up to that. get_bike_share uses the radius as
registered, so assert each system's radius reaches the stations it lists.

Subject: [PATCH 68/76] fix(bikeshare): drop stations outside a city's load
 radius
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Bogotá's and Santiago's PBSC feeds list depot stations in São Paulo and
Madrid as installed and renting, so activating either city drew live
docks thousands of kilometres away and counted them in the layer total.
Station information is now limited to the city's registered load radius;
every other registered feed already sits inside its radius (checked live
2026-10-16), so nothing else changes.

Adds a Bogotá/Santiago registry test matching the Brazilian and Barcelona
ones: proxy allowlist, outermost-station activation and radius reach, and
the depot filter through the real ingestion path.

Subject: [PATCH 69/76] i18n: fix the final pre-merge review findings

Fixes the P1 and the confirmed P2 findings of the final review of the
i18n branch.

- CI: the air-quality model no longer imports i18n (portable module),
  so check:boundaries passes again.
- Air quality layer: named in the layer panel, HUD and voice; its
  Weather card, bands and errors translate. A test keeps the layer-name
  table in step with the layer registry.
- Layer statuses that still reached ru/es in English: GNSS, CelesTrak,
  Transit loading and feed errors, launches, perimeters, ALPR, ECCC,
  wind "field unavailable", Local ADS-B streaming lines.
- Voice and HUD: preset ids show city names ("Fly to San Francisco"),
  the HUD city translates, cockpit refusals cover frame, aircraft and
  satellite; empty Transit notes translate on the analyst card.
- tn() keeps a caller's formatted count ("12,345 map objects").
- Cyber HUD: the language button no longer covers the bottom-right
  card or the cockpit position readout.
- CCTV buttons wrap only in non-English locales; English layout matches
  main again.
- Switching language asks first when Provider Settings holds unsaved
  keys.

Catalogs: es/ru 2611 messages each, complete.

Subject: [PATCH 70/76] Revert hiding vessel detection callouts under ambient
 cards

The vessels layer hid the detection callout for every vessel whose card
it published to the world overlay. The overlay paints only part of the
published cards (shared budget, collisions, UI chrome), so vessels whose
card was dropped lost all their text: with 60 vessels and Detection on,
21 showed only an arrow. Back to main's behaviour: the callout always
draws. Hiding it only under a painted card is HAL-628.

The translated speed unit in the callout stays.

Subject: [PATCH 71/76] i18n: fix the repeat-review findings

- Status pieces translate in one place (src/ui/statusText.js): a Local
  ADS-B error with a single piece now translates, and the analyst card
  splits empty-layer notes into pieces (Transit, Local ADS-B).
- Translate the ALPR retry chip text, the ECCC error on the Air quality
  card, "Upstream response too large" and the "entry {n}" feed label.
- The unmarked-text check also sees error/loadingLabel/statusMessage/
  status assignments, `status:` properties and showToast?.( /
  this._showToast( calls; the scene import preview marks its pack
  statuses, data and model-facing text carry i18n-ignore with a reason.
- Tests check the real code: the HUD locality formatter moves to
  src/hudLocalityFormat.js, the unsaved-keys test pins the teardown.
- One copy each: city names come from src/cityPois.js, the GNSS HTTP
  template and wind "field unavailable" texts; dead fallbacks removed.
- Leftovers of the reverted vessel-label change and the reformatting of
  detectionHost.test.mjs / keySetup.test.mjs are back to main.

Catalogs: es/ru 2617 messages each, complete.

Subject: [PATCH 72/76] fix(sdr): bound decoder work and stabilize FM playback

Keep USB reads in a bounded ordered pipeline, acknowledge and cap decoder
work, terminate stopped workers, and buffer short playback jitter. Throttle
display telemetry and compute spectra only while seeking.

Preserve PR #1174's wrapped seeking and fresh-spectrum tagging. Add opt-in
bounded timing diagnostics and decoder/playback lifecycle regressions.

 # Changelog
 
+- Local FM seek finds stations after wrapping around 87.5–108 MHz, covers both
+  band edges, skips the starting station and rejects spectra from an earlier
+  tune (Aditya, @Rohilalala, #1174).
+- Local RTL-SDR keeps USB reads queued in order and bounds pending decoder
+  work. A stalled or overloaded decoder stops with an explicit error; stopping
+  terminates its worker and rejects late audio. FM playback buffers short
+  scheduling gaps, caps its audio queue at 256 ms, and reduces display updates
+  and spectrum calculations while listening.
+
 - Add Bogotá (Tembici, 250 stations) and Santiago de Chile (Bike Itaú, 200
   stations) to the GBFS bikeshare registry, the layer's first stations in
   Colombia and Chile. Both are PBSC feeds like the Brazilian Bike Itaú cities,

 internet-radio playback, and starting internet radio stops local FM. ADS-B
 reception does not interrupt internet radio.
 
+- **FM seek.** Seeking wraps across 87.5–108 MHz, covers both band edges and
+  skips the starting station. Spectra carry a decoder epoch, so a retune or mode
+  change rejects earlier output. A failed scan retune stops seeking. This
+  integrates Aditya's (@Rohilalala) contribution in #1174; it does not change
+  the peak-selection algorithm or guarantee that a final station retune succeeds.
+- **Streaming and playback.** Four ordered USB reads keep input available while
+  the page handles other work; control changes drain those reads before touching
+  the receiver. The worker must finish loading before reads start. Decoder work
+  is limited to eight unacknowledged blocks / 512 KiB, with a one-second oldest
+  block watchdog. Overload stops the receiver with an explicit error. Stop
+  terminates the worker immediately and disables the audio session; stale decoder
+  output and audio from retired sessions are refused. FM audio starts after an
+  80 ms prebuffer and retains at most 256 ms, dropping the oldest frames on
+  overflow. FM signal display updates are coalesced to at most four per second;
+  spectra are computed only while seeking. Optional `decoderDiagnostics` adds
+  bounded timing samples and overload snapshots without recording audio or IQ.
 - **Modes.** FM (87.5–108 MHz, tune, seek, volume) or ADS-B at 1090 MHz.
   With a receiver open, selecting ADS-B enables the Local ADS-B layer;
   selecting FM disables it.

+A module the server, tools or other portable code also imports must not load the catalogs: it imports `msg` from `src/i18n/marker.js`, which only marks the text, and the UI translates it with `t()` where it shows it. (Older modules keep a local `const msg = (text) => text`, which works the same.)

  * qa-scene-dialog-file-drop — the SHARE SCENE dialog's file control accepts a
  * file dropped from the desktop, proved in a real browser.
  *
- * The dialog replaces the browser-drawn "Choose files / No file chosen" line
- * with a translated one (src/ui/sceneSharing.js, fileChooser). The native
- * input must stay the whole control underneath it: a shrunken 1 px input
- * accepts drops only on its own pixel, so dragging a data-pack file onto the
