Core told time eight ways: Date.now() in most layers, JulianDate.now() for
flights and military, Cesium's clock frozen at page load for the sky, the
weather clock for observed imagery. They now read one clock,
src/time/worldClock.js, exported as ./time.
Live is a mode, not a timestamp: while live the clock is the wall clock,
so every layer draws as before. Away from live only the layers that follow
the clock move with it. The weather products follow it, as they followed
the weather transport; a host opts others in with follow(id).
- The weather clock takes its time from the world clock and drives its
replay, stepping its frames as before.
- Satellites, launches, flights and military (still 30 s and 15 s behind),
transit, GNSS, Recent Imagery, street level, the HUD and the celestial
ring read worldTimeFor(id). Cadences stay on the wall clock.
- Cesium's sky (stars, sun, moon, atmosphere, lighting) draws at the world
time each frame instead of the moment the page loaded.
- Weather frames and satellites declare coverage() for a host's timeline.
Review on #855: the per-aircraft rule (NIC < 7 || NACp < 8, borrowed from
the US 14 CFR 91.227 ADS-B Out minima) is GEV-defined, not gpsjam's, and
gpsjam's map shows low navigation accuracy, not necessarily jamming.
- Primary cell state is now `navigation-integrity-anomaly` (medium/high) or
`nominal`; `suspected-gnss-interference` is a secondary `interpretation`
marked validated: false.
- GNSS_PROVENANCE / gnssProvenance({ windowMs }) records the classifier
(gev-nic-nacp-v1, GEV, unvalidated), the gpsjam aggregation (formula,
bands [0.02, 0.1], FAQ source) and the GEV 30-minute visited-view window,
built from the constants the code applies. Exposed as layer.provenance
and getStats().provenance; the proxy tags responses with `classifier`.
- Visible name "GNSS Integrity", legend "... low accuracy", blurb leads with
low navigation accuracy and states the threshold is a GEV choice.
- Layer id `gnss-interference` and share token `0` unchanged.
- Voice aliases add "gnss integrity", "navigation integrity",
"low navigation accuracy"; the interference aliases stay.
- Docs describe the method as GEV threshold + gpsjam aggregation.
- Tests: provenance object, renamed state/label, proxy classifier tag;
qa-gnss asserts provenance and wording in the real app.

- Route the adsb.lol GNSS source through createReferenceSources and the
constructCatalog contract; app layer module is a thin pass-through.
- Describe the method honestly: gpsjam.org's published cell formula and
bands; per-aircraft thresholds are the 14 CFR 91.227(c) ADS-B Out minima
(NIC < 7, NACp < 8) plus readsb gpsOkBefore.
- Proxy: reuse the adsb.lol anchor parser, honour upstream Retry-After
(clamped 5-120 s), serve stale during cooldown, cap the body size.
- Layer: redraw only when a cell id or band changes, treat a settling
camera as a retry rather than a rejected enable, keep low cells visible,
skip rows without finite coordinates, state the 3-aircraft rule in the
legend blurb.
- Voice: gnss-interference in set_layer_visibility / show_data_layers_menu
plus common aliases; voice pins re-derived.
- qa-gnss: stub the route in-page (request interception stalls Cesium's
geometry workers), assert every cell is built, cover all bands over land
and sea, screenshot every state with the Data Layers row open.

Bins airborne ADS-B v1/v2 aircraft that report degraded navigation
integrity (NIC < 7, NACp < 8, or readsb's GPS-loss flag) into 0.5 degree
cells over a rolling 30-minute window, coloured with the gpsjam.org
bands. Keyless: reads the capped adsb.lol point snapshot around the view
through /api/gnss-integrity, which returns integrity fields only, caches
60 s per whole-degree anchor, backs off on upstream 429 and serves the
last snapshot on failure. Adds scripts/qa-gnss.mjs.
