# God's Eye View Current State
Shared distance checks use `src/geoDistance.js` with `{ lat, lon }` points and
the IUGG mean spherical Earth radius, 6371.0088 km. `greatCircleKm` is
canonical; `greatCircleMeters` is its exact metre conversion. Missing,
non-finite, and out-of-range points (latitude outside ±90, longitude outside
±180) return `Infinity`, so threshold and nearest-item consumers exclude invalid
positions. Older exported `haversineKm` entry points remain as compatibility
wrappers only. `src/data/approxDistance.js`, the equirectangular
viewer-proximity approximation, is deliberately separate, as are intentional
local angular, projection, ellipsoidal prefilter, and small-viewport
approximations. Four great-circle copies remain for a follow-up:
`src/data/adminBoundaries.js` and `src/tools/area.js` pass unwrapped longitudes
across the antimeridian, so they cannot use the strict ±180 check as-is, and
`src/sources/adsbRecords.js` and `server/providers/common/geo.js` keep their own
implementations.

- **The DENSE chip reports the dense LOAD, not the catalog param.** The param flips synchronously while the Starlink shell takes seconds to arrive over a chunked load, and CelesTrak 502s that feed regularly. So the chip reads `DENSE ···` (busy, disabled) while loading, ACTIVE only once dense points are actually on screen, and `DENSE ✕` with the reason on hover when the load fails — a failure also reverts `catalog` to `core`, drops any partial chunk, and leaves the chip clickable to retry. A load is judged by points added, not by HTTP status: a 200 carrying an empty body, a passed-through HTML error page, or only TLEs the core catalog already owns fails with the same revert semantics as a 502. Any explicit request for `core` clears a latched error even when the mode does not change, so a Space Missions restore of an already-core snapshot never leaves the user with a failure they did not cause. Because the load settles asynchronously, the layer pushes a re-render through the optional `setRowControlsListener()` hook; nothing else would repaint that row before the 5-minute catalog refresh, so the count and legend would otherwise sit stale.
- **A dependency owner takes the row with it.** Space Missions borrows this layer for TLE lookup with `showPoints:false`; while points are hidden the layer returns empty row controls, so the legend never describes an empty sky and the chip cannot accept a write that the owner's restore would silently revert.
- The detection-overlay record cache (`_detectionObjects`) is cleared with the catalog on every rebuild: it stamps id/class at creation only, and a rebuild can re-tag a satellite when a partial CelesTrak outage changes which group wins dedupe.
- **Catalog numbers above 99999** can be written in a TLE as Alpha-5: a letter A–Z, skipping I and O, for the first two digits, so `A0000` is 100000 and `Z9999` is 339999. CelesTrak's TLE feed carries no satellite above 99999 (that needs the OMM feed, #1191), so this is compatibility with Alpha-5 TLEs. `src/sources/tle.js` decodes the field through one shared helper: `noradIdFromSatnum()` for the satellites layer, which keys and deduplicates its catalog by that number, and `tleCatalogNumber()` for the satellite tools. Plain digits read as before (`noradIdFromSatnum()` accepts any length, as an OMM satrec carries the number unpadded); a malformed field — a sign, decimal point, hex, exponent, embedded space, stray or lowercase letter, or blank — is rejected rather than partly read, as `NaN` in the layer and `null` in the tools.
