Subject: [PATCH 02/33] perf(flights): skip dead-reckoning contacts that stay
 behind the horizon

The fleet tick dead-reckoned, floored and distance-tested every contact on
every ~80 ms tick, then hid the ones behind the horizon. The worldwide feed
carries ~13k contacts; zoomed in, well under 1% are on screen, so nearly all
of that work produced a hidden billboard.

A contact that is already hidden and still behind the horizon at its last
position now re-reckons only on its turn in a staggered one-in-12-ticks
rotation (about once a second, HIDDEN_CONTACT_DR_TICKS). Anything that
position puts in view, and any contact with a fleet model, takes the full
pass immediately, so on-screen behaviour is unchanged. Hidden-inclusive
proximity queries (getNearby includeHidden, getAllPositions) read positions
at most about a second old, well inside the 30 s poll's uncertainty.

Measured in Chrome on a Radeon 780M, ~12.9k contacts, 56 on screen over
Colombia at 4 km, same view before and after:
  fleet tick   7.66 -> 2.03 ms/frame, longest tick 50.9 -> ~16 ms
  frame        20.6 -> 14.0 ms, 42.9 -> 57.8 FPS
Teleporting the camera to Madrid showed 975 contacts within 100 ms.

+  tick from 51 ms to about 16 ms; the scene goes from 43 to 58 FPS. Hidden
+  contacts re-reckon about once a second, staggered, and appear as soon as

 ### Motion & Symbology Correctness (June 10, 2026)
 
-- **Flights (commercial + military)** render one poll interval behind real time (30s/15s) and interpolate between two known feed-stamped fixes (OpenSky `time_position`; adsb.lol `receipt − seen_pos`). The display latency is an intentional product decision — do not "fix" it away. The whole fleet dead-reckons at ~12Hz (1m² write gating); aircraft get a 3-poll grace period (faded icon) before removal. When a position epoch pauses, both layers coast for at least 60 seconds of contact grace with an absolute five-minute ceiling. Source backoff marks each contact and the cockpit `STALE`; the cockpit then holds the exact layer position instead of continuing inertial flight. Repeated-position kinematic changes create a forward-only synthetic fix rather than mutating history, and grounded history is lifted only when no owned 3D model already controls its datum. A nominally successful worldwide OpenSky response whose own snapshot epoch is more than two minutes old prefers the existing 250-nm viewport-scoped adsb.lol fallback and labels the source/coverage accordingly when that upstream is available. If the fallback is also unavailable, the layer's freshness/error fields use the source epoch—never the cache receipt time—so the UI reports an old snapshot rather than “just now.”

If the fallback is also unavailable, the layer's freshness/error fields use the source epoch—never the cache receipt time—so the UI reports an old snapshot rather than “just now.”
 - **World-space headings at every angle** (`src/data/iconOrientation.js`): aircraft/vessel icon rotation uses the camera right/up basis per tick (alignedAxis always ZERO), which is exact at screen center and for orthographic/nadir views and remains stable through >180° tracked orbits. Perspective rays vary across the viewport, so off-center contacts at oblique pitch can diverge from an exact finite-difference window projection; a regression test pins that known regime, and field evidence decides whether to adopt exact projection with the basis method as fallback. Fleet rotations refresh on camera-pose change; tracked entities per frame. Billboards are horizon-culled via a shared EllipsoidalOccluder.
 - **Military/OpenSky reconciliation** (`src/data/militaryRegistry.js`): known-military ICAOs render amber in the flights layer (60s self-poll of the cached mil endpoint when the military layer is off) and are suppressed there while the military layer renders them.
 - **Satellites**: 838-sat core catalog (stations/visual/GPS/GLONASS/Galileo/GEO), tracking lands ~726km out via `viewFrom` (tracked entity owns a point graphic so the tracking camera engages), rings realign via primitive modelMatrix (no per-second rebuild flicker), optional `setParams({catalog:'dense'})` Starlink mode.

Subject: [PATCH 03/33] data: refresh Norway datacenters from Geofabrik extract

Add a maintainer script that merges a pinned, MD5-verified Geofabrik Norway
extract (osmium tags-filter telecom/building=data_center) into the bundled
datacenter layer. Only features inside the Geofabrik Norway boundary are
touched; unchanged features keep their original line.

norway-261005 (OSM 2026-10-05) adds Troll Housing (w1551029155) and updates
tags on four existing features. Provenance is recorded in the dataset README
and the bundled count moves from 4,351 to 4,352.

+- Refresh Norway's datacenters from a Geofabrik OpenStreetMap extract
+  (2026-10-05). Troll Housing joins the layer (4,352 features) and four

+  touching only features inside Geofabrik's Norway boundary, and the dataset
+  README records the extract, checksum and filter.

Subject: [PATCH 04/33] fix(data): make the Norway datacenter script portable
 and re-runnable

Read and write files as UTF-8 with LF line endings so the script and
--verify work on Windows, where the default codec is cp1252 (thanks to
quanticsoul4772 for the report). Geofabrik keeps only its newest dated
extract, so --extract now defaults to the current one and accepts a dated
name for --verify while it is listed; the dataset README says so. Downloads
time out instead of hanging.

-- **Flights (commercial + military)** render one poll interval behind real time (30s/15s) and interpolate between two known feed-stamped fixes (OpenSky `time_position`; adsb.lol `receipt − seen_pos`). The display latency is an intentional product decision — do not "fix" it away. The fleet dead-reckons at ~12Hz (1m² write gating); a contact already hidden behind the horizon whose last position still is re-reckons on a staggered one-in-12-ticks rotation (about once a second) instead, so the worldwide feed's ~13k contacts no longer cost a full pass when well under 1% are on screen. Anything that position puts in view, and any contact with a fleet model, takes the full pass immediately, and hidden-inclusive proximity queries read positions at most about a second old; aircraft get a 3-poll grace period (faded icon) before removal. When a position epoch pauses, both layers coast for at least 60 seconds of contact grace with an absolute five-minute ceiling. Source backoff marks each contact and the cockpit `STALE`; the cockpit then holds the exact layer position instead of continuing inertial flight. Repeated-position kinematic changes create a forward-only synthetic fix rather than mutating history, and grounded history is lifted only when no owned 3D model already controls its datum. A nominally successful worldwide OpenSky response whose own snapshot epoch is more than two minutes old prefers the existing 250-nm viewport-scoped adsb.lol fallback and labels the source/coverage accordingly when that upstream is available. If the fallback is also unavailable, the layer's freshness/error fields use the source epoch—never the cache receipt time—so the UI reports an old snapshot rather than “just now.”

 - **World-space headings at every angle** (`src/data/iconOrientation.js`): aircraft/vessel icon rotation uses the camera right/up basis per tick (alignedAxis always ZERO), which is exact at screen center and for orthographic/nadir views and remains stable through >180° tracked orbits. Perspective rays vary across the viewport, so off-center contacts at oblique pitch can diverge from an exact finite-difference window projection; a regression test pins that known regime, and field evidence decides whether to adopt exact projection with the basis method as fallback. Fleet rotations refresh on camera-pose change; tracked entities per frame. Billboards are horizon-culled via a shared EllipsoidalOccluder.
 - **Military/OpenSky reconciliation** (`src/data/militaryRegistry.js`): known-military ICAOs render amber in the flights layer (60s self-poll of the cached mil endpoint when the military layer is off) and are suppressed there while the military layer renders them.
 - **Satellites**: 838-sat core catalog (stations/visual/GPS/GLONASS/Galileo/GEO), tracking lands ~726km out via `viewFrom` (tracked entity owns a point graphic so the tracking camera engages), rings realign via primitive modelMatrix (no per-second rebuild flicker), optional `setParams({catalog:'dense'})` Starlink mode.

 - **What it shows.** Events ▸ **S2 GhostMaps** draws the current edition of S2 Underground's KMZ intel products from `github.com/s2underground/GhostMaps`. The products are the Common Intelligence Picture and the 30-day kinetic pull (both on by default), the Border Crisis Map, the Iran Common Intelligence Picture, Iran Kinetic Events, Yemen FLOT, and **Latest Drop**: the newest dated incident file outside those series, `0_Archive`, `Basedata` and `Reference Material`. Each product has a chip in the row. The chip choice is kept in `localStorage` (`gev.ghostmaps.products`) and falls back to the defaults when storage is blocked.
 - **Editions.** `src/layers/ghostMaps/catalog.js` (pure) matches whole repository paths per product. The newest edition wins by the date written in the file name, then by `Export_N`/`vN`. Undated names, such as the fixed 30-day file, are identified by blob sha. Files over 50 MiB are left out (the 62 MB census KMZ, for example). A renamed folder drops the product rather than matching elsewhere.
+- **Event age filter.** The same filter applies to every selected S2 product, including Border Crisis, Iran Picture, Iran Kinetic, Yemen FLOT and Latest Drop. S2 products default to seven days, with row buttons for 1, 3, 7, 14 or 30 days and **All markers**. The choice persists independently of product selection in `localStorage` (`gev.ghostmaps.ageDays`); missing, invalid or blocked storage uses seven days. Only the placemark's `Date of Event` (or `EventDate`/`Date`) determines its age, never report dates, dates in prose or KMZ edition/upload dates. Undated, blank or unparseable event dates and future dates stay visible. ArcGIS `M/D/YYYY` dates and optional AM/PM times, plus ISO dates/timestamps, are supported; values without a zone use UTC and date-only values use midnight UTC. The exact cutoff is included. Events age out every minute and during catalog updates, even without a new file or a successful catalog fetch. Widening the window or choosing All markers restores omitted events from the cached KMZ. Removed entities and selected cards disappear together; surviving pick ids stay stable. Product defaults and the update stream are unchanged.
 - **Updates.** The repository is not ours, so there is no webhook. `server/providers/ghostMaps.js` starts with the first `/api/ghostmaps` request, so an install that never enables the layer never contacts GitHub.
   - It reads the branch head from git's smart-HTTP ref advertisement (`/info/refs?service=git-upload-pack`, about 0.5 KB, outside the REST rate limit) every `GHOSTMAPS_POLL_SECONDS` (15 s by default, 5 s minimum). Failures back off from 15 s to 5 min.
   - Only a new head costs REST calls: one recursive tree and one commit. An optional `GITHUB_TOKEN` raises the REST limit.

Subject: [PATCH 15/33] fix(datacenters): report newly tagged features osmium
 cannot export

line. A newly tagged one had nowhere to go and was dropped silently; it is
now listed as skipped with a warning, so a refresh never loses a site or
hides a broken one.

+- Fix the translations of the voice area cards, the fire confidence filter,
+  the drone airspace layer and Sea Marks: one word for "landmark" per

Subject: [PATCH 19/33] fix(geocode): keep a leading "the" in keyless name
 matching
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

foldPlaceName drops a leading "the", so "The Hague" over upstate New
York accepted Hague, NY as an exact nearby match. Split the script-aware
fold into foldPlaceText and use it for keyless toponyms; foldPlaceName
keeps its behaviour for the packs and street matchers.

Also: changelog fragment credits #1585, folding test pins the Latin
letters NFD does not decompose (ß, ø, ł), and CURRENT-STATE notes that
non-Latin names match only when spelled with their marks.

Subject: [PATCH 21/33] chore(datacenters): drop the one-off Norway refresh
 script

The data refresh is committed and its provenance (extract, timestamp, MD5,
filter) stays in the dataset README. The script needed osmium-tool and could
only re-verify while Geofabrik still listed that extract, so it goes with its
test.

Subject: [PATCH 27/33] fix(cyclones): name the classification and mark a stale
 cache in shared context

- Publish classificationName next to the raw NHC code; unknown codes stay
  unexpanded.
- Publish staleCacheFetchedAt only while the proxy serves its cache.
- Touch the shared store on clear only after this layer published, so a
  feed failure no longer evicts another layer's dangling selection.
- Drop the unreachable no-storm branch and the unused return value.
- Tests: split the heading fixture into due north and stationary, cover
  the unavailable and failure paths with the real store, and check that
  clear/disable leave another layer's selection alone; fold the fake-store
  test into the real-store one.

Subject: [PATCH 30/33] fix(ghostmaps): keep age-window changes consistent and
 make the age choice a switch

Review fixes on top of #1528:
- Narrowing the age window only removes markers; a product loaded with a
  narrower window is reloaded when the window widens again. Fixes markers
  missing after 7d -> 1d -> 7d and avoids reparsing every KMZ on narrowing.
- A wider window over the same edition keeps the open report card.
- Date-only event dates cover their whole UTC day, so 1d still shows
  yesterday's reports.
- The age options are one labelled "Event age" radio switch (row
  `segmented` control, as FIRMS confidence) instead of toggle chips mixed
  with the product chips.
- Un-nest the per-product age test; QA compares data-source counts with the
  live defaults instead of a hard-coded 2.

 - **What it shows.** Events ▸ **S2 GhostMaps** draws the current edition of S2 Underground's KMZ intel products from `github.com/s2underground/GhostMaps`. The products are the Common Intelligence Picture and the 30-day kinetic pull (both on by default), the Border Crisis Map, the Iran Common Intelligence Picture, Iran Kinetic Events, Yemen FLOT, and **Latest Drop**: the newest dated incident file outside those series, `0_Archive`, `Basedata` and `Reference Material`. Each product has a chip in the row. The chip choice is kept in `localStorage` (`gev.ghostmaps.products`) and falls back to the defaults when storage is blocked.
 - **Editions.** `src/layers/ghostMaps/catalog.js` (pure) matches whole repository paths per product. The newest edition wins by the date written in the file name, then by `Export_N`/`vN`. Undated names, such as the fixed 30-day file, are identified by blob sha. Files over 50 MiB are left out (the 62 MB census KMZ, for example). A renamed folder drops the product rather than matching elsewhere.
-- **Event age filter.** The same filter applies to every selected S2 product, including Border Crisis, Iran Picture, Iran Kinetic, Yemen FLOT and Latest Drop. S2 products default to seven days, with row buttons for 1, 3, 7, 14 or 30 days and **All markers**. The choice persists independently of product selection in `localStorage` (`gev.ghostmaps.ageDays`); missing, invalid or blocked storage uses seven days. Only the placemark's `Date of Event` (or `EventDate`/`Date`) determines its age, never report dates, dates in prose or KMZ edition/upload dates. Undated, blank or unparseable event dates and future dates stay visible. ArcGIS `M/D/YYYY` dates and optional AM/PM times, plus ISO dates/timestamps, are supported; values without a zone use UTC and date-only values use midnight UTC. The exact cutoff is included. Events age out every minute and during catalog updates, even without a new file or a successful catalog fetch. Widening the window or choosing All markers restores omitted events from the cached KMZ. Removed entities and selected cards disappear together; surviving pick ids stay stable. Product defaults and the update stream are unchanged.
+- **Event age filter.** One **Event age** switch in the S2 GhostMaps row applies to every selected product: 1, 3, 7 (default), 14 or 30 days, or **All markers**. The choice is saved separately from product selection in `localStorage` (`gev.ghostmaps.ageDays`); missing, invalid or blocked storage falls back to seven days. Age comes only from the placemark's `Date of Event` (or `EventDate`/`Date`), never from report, prose or KMZ edition dates. Undated, unparseable and future dates stay visible. ArcGIS `M/D/YYYY` dates with optional AM/PM times and ISO dates are read as UTC when no zone is given; a date without a time covers its whole UTC day, so **1d** still shows yesterday's reports. Events age out every minute while the layer is on. Narrowing the window only removes markers; widening restores them from the cached KMZ. An open card stays while its marker is shown.
 - **Updates.** The repository is not ours, so there is no webhook. `server/providers/ghostMaps.js` starts with the first `/api/ghostmaps` request, so an install that never enables the layer never contacts GitHub.
   - It reads the branch head from git's smart-HTTP ref advertisement (`/info/refs?service=git-upload-pack`, about 0.5 KB, outside the REST rate limit) every `GHOSTMAPS_POLL_SECONDS` (15 s by default, 5 s minimum). Failures back off from 15 s to 5 min.
   - Only a new head costs REST calls: one recursive tree and one commit. An optional `GITHUB_TOKEN` raises the REST limit.

Subject: [PATCH 31/33] fix(ghostmaps): follow-up review fixes for the age
 switch

- Keep the open card across a widened reload only when its index still
  holds the same report; the server may answer a pinned version with newer
  bytes.
- Narrowing to a window the loaded data already covers clears a failed
  wider reload, so the row no longer stays in error.
- Label the every-age option "All" (contextual) so the six-option switch
  fits the row in every locale; tooltip and info line keep "All markers".

 - **What it shows.** Events ▸ **S2 GhostMaps** draws the current edition of S2 Underground's KMZ intel products from `github.com/s2underground/GhostMaps`. The products are the Common Intelligence Picture and the 30-day kinetic pull (both on by default), the Border Crisis Map, the Iran Common Intelligence Picture, Iran Kinetic Events, Yemen FLOT, and **Latest Drop**: the newest dated incident file outside those series, `0_Archive`, `Basedata` and `Reference Material`. Each product has a chip in the row. The chip choice is kept in `localStorage` (`gev.ghostmaps.products`) and falls back to the defaults when storage is blocked.
 - **Editions.** `src/layers/ghostMaps/catalog.js` (pure) matches whole repository paths per product. The newest edition wins by the date written in the file name, then by `Export_N`/`vN`. Undated names, such as the fixed 30-day file, are identified by blob sha. Files over 50 MiB are left out (the 62 MB census KMZ, for example). A renamed folder drops the product rather than matching elsewhere.
-- **Event age filter.** One **Event age** switch in the S2 GhostMaps row applies to every selected product: 1, 3, 7 (default), 14 or 30 days, or **All markers**. The choice is saved separately from product selection in `localStorage` (`gev.ghostmaps.ageDays`); missing, invalid or blocked storage falls back to seven days. Age comes only from the placemark's `Date of Event` (or `EventDate`/`Date`), never from report, prose or KMZ edition dates. Undated, unparseable and future dates stay visible. ArcGIS `M/D/YYYY` dates with optional AM/PM times and ISO dates are read as UTC when no zone is given; a date without a time covers its whole UTC day, so **1d** still shows yesterday's reports. Events age out every minute while the layer is on. Narrowing the window only removes markers; widening restores them from the cached KMZ. An open card stays while its marker is shown.

 - **Updates.** The repository is not ours, so there is no webhook. `server/providers/ghostMaps.js` starts with the first `/api/ghostmaps` request, so an install that never enables the layer never contacts GitHub.
   - It reads the branch head from git's smart-HTTP ref advertisement (`/info/refs?service=git-upload-pack`, about 0.5 KB, outside the REST rate limit) every `GHOSTMAPS_POLL_SECONDS` (15 s by default, 5 s minimum). Failures back off from 15 s to 5 min.
   - Only a new head costs REST calls: one recursive tree and one commit. An optional `GITHUB_TOKEN` raises the REST limit.

Subject: [PATCH 32/33] fix(street-level): keep explicit provider choices on
 filter-only updates
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Review fixes on top of #1601:
- Only redirect a provider the params switch on to a keyless source, so a
  filter-only setParams (360°, SINCE) no longer moves an explicitly chosen
  keyless Mapillary to KartaView.
- Keyless QA gate: assert the new KartaView default and that the Mapillary
  chip explains its key instead of switching (it used to expect KEY REQUIRED).
- Tests: Graph-proxy keyReady, filter-only updates; shared test helper.
- README and CURRENT-STATE describe the keyless default.

 > Street-level photos from any provider in one panel. This build ships **Mapillary** (a free client token), **Google Street View** (your Google Maps key), **KartaView** and **Panoramax** (no key).
 
-**Setup.** At [mapillary.com/dashboard/developers](https://www.mapillary.com/dashboard/developers), register an application with **Read** access and copy its **Client Token** (`MLY|…`). Paste it into **POWER UP → Mapillary**, or set `MAPILLARY_CLIENT_TOKEN` in `.env` and restart. Without it the panel reads **KEY REQUIRED**. **Google Street View** uses `GOOGLE_MAPS_API_KEY` with the **Maps JavaScript API** enabled for it in Google Cloud; its chip starts off, since every panorama is billed to the key. **KartaView** and **Panoramax** need nothing: their public APIs are keyless.
+**Setup.** At [mapillary.com/dashboard/developers](https://www.mapillary.com/dashboard/developers), register an application with **Read** access and copy its **Client Token** (`MLY|…`). Paste it into **POWER UP → Mapillary**, or set `MAPILLARY_CLIENT_TOKEN` in `.env` and restart. Without it Street Level starts on **KartaView** instead, and the Mapillary chip says which key to add. **Google Street View** uses `GOOGLE_MAPS_API_KEY` with the **Maps JavaScript API** enabled for it in Google Cloud; its chip starts off, since every panorama is billed to the key. **KartaView** and **Panoramax** need nothing: their public APIs are keyless.
 
-**Use.** Turn on **Street Level** under DATA LAYERS → Cameras, or with the pill in the STREET LEVEL panel header. Each provider has a chip in its own colour (Mapillary green), and one is lit at a time: lighting one switches the others off. Mapillary, which is free, is lit by default. Zoom in to street level (below 60 km) for the coverage lines; from orbit the panel says to zoom in. The **IMAGERY** (ALL / 360° / FLAT) and **SINCE** filters apply to Mapillary, KartaView and Panoramax; Street View panoramas are all 360°, so with Street View lit the filters are hidden. Click a coverage line for its image cones and a cone to open the photo. Light **KARTAVIEW** (purple) and zoom in below about 6 km: its lines are the streets KartaView has photos of, and a click on one opens the photo nearest the click, flat or 360° (drag to look around), with cones along its drive; **‹ ›** or ← → step through the drive (Shift+← →, ↑ ↓ and + − look around a 360° photo; pinch zooms on a phone). Photos KartaView has archived are skipped, and where all are archived the panel says so. For KartaView, **SINCE** goes by upload date, as KartaView's own map does (it can filter by nothing else), and the panel notes it beside the SINCE value (ANY DATE (by upload date)); KartaView filters its lines on its own server, and a filtered area KartaView has not drawn before can take several seconds. Light **PANORAMAX** (orange) for the open, federated commons (strongest in France and Belgium): below about 60 km its lines are sequences. A click on a line opens that sequence's picture nearest the click without moving the camera, flat or 360°, with cones along the sequence around it; **‹ ›** or ← → step through it, and both filters apply. Its caption names the picture's authors (or the instance holding it) and licence (mostly CC BY-SA 4.0; pictures on the IGN instance are Licence Ouverte 2.0). On the **Google 3D** map (Google's terms keep Street View off other maps, where it does not appear), light **GOOGLE STREET VIEW** and click a street from below 3 km, or press **OPEN STREET VIEW** for the view centre, to open Google's panorama there; step along its arrows. Above the photo: **EXPAND** (full screen; Esc leaves) and **FIT / FILL** (Mapillary, and flat KartaView and Panoramax photos). The caption links to the image on the provider's site, and the globe credits each provider that is on ("© Mapillary contributors, CC BY-SA 4.0", "Street View imagery © Google", "© KartaView contributors, CC BY-SA 4.0", "© Panoramax contributors, licence per picture"). KartaView's own photo pages fail for signed-out visitors, so its link opens the full-size photo.

 Share links carry the provider switches and filters (`0.m.0` Mapillary off, `0.m.0_0.r.google-1` Street View on, `0.m.0_0.r.google-0*kartaview-1*panoramax-0` KartaView on and `0.m.0_0.r.google-0*kartaview-0*panoramax-1` Panoramax on, as the app writes them (`0.m.0_0.r.kartaview-1` and `0.m.0_0.r.panoramax-1` work too; a link that leaves out `m` keeps Mapillary, the default, lit), `0.p.p` panoramas only, `0.s.365` the last year). To add a provider, implement the contract in `src/layers/streetLevel/registry.js` and register it in `src/app/layers/streetLevel.js`.
