Each /api/wind refresh decoded two or three 0.25 degree GRIB2 messages with
ecCodes (WASM), validated ~1.04 M doubles per message and resampled them, all
synchronously on the server thread. Measured with cached upstream bytes: 43
to 164 ms of event-loop block per warm refresh, 230 to 381 ms for the first
one in a process, 316 to 974 ms when all six keys refresh together.
Decode, validation and resampling now run on one lazily started worker
thread, which transfers back only the display-grid samples. The server keeps
the sampled U/V of the last forecast object per model (1.04 MB each), so an
overlay change, or a refresh within the same forecast step, fetches and
decodes only the scalar. Manifests and grid bodies are byte-identical to
before for the same upstream bytes.

Knip, configured with the application, package exports, scripts, QA
harnesses, workers, tools and tests as entry points, reports exports
that no module imports. Each was checked by hand against string-based
and namespace imports.
- Symbols that are still used inside their own module lose only the
`export` keyword (176 constants and helpers).
- Unused re-exports are removed from barrel modules (flight, military,
vessel, CCTV, directions, transit history, local ADS-B and street-level
policy modules).
- Declarations that nothing uses at all are deleted, among them
AIS_WATCHDOG_STATUSES, applyFilter, isRadioCountryCode, compactText,
DENSITY_STOPS, the unused CCTV endpoint constants, and the SDR band
constants.
- Default exports that nothing imports are removed. The ones in
src/data/earthquakes.js, src/data/telegeographySubmarineCables.js,
src/data/wind.js and src/data/bhoteKoshiLocator.js each constructed a
layer instance at import time that nothing used; those instances are
no longer created.
Every export of a package.json entry stays, as does TOMTOM_CREDIT,
which the traffic layer reads from the credits namespace it is given.
Wind (NOAA GFS and ECMWF IFS: animated particles, colour field, a reading at map centre), observed weather (NOAA MRMS radar, GOES and NESDIS infrared clouds, lightning density) on one shared history timeline, NHC and CPHC cyclone advisories with tracks and cones, and a WEATHER panel in the right rail. On 3D Tiles the observed products render as raised shells with a sharper window around the view.
