main renamed the flights proxy mount from /api/opensky to /api/flights. Git
took the new mount cleanly but left this branch's own tests and notes on the
old path, and the compression test then failed. They now use /api/flights.
A 429 now starts the credit cooldown from its headers and drops the body
unread, so a stalled or oversized 429 cannot skip the governor; an oversized
snapshot is not retried. A 429 without retry-after now waits the intended
2 minutes (headers.get() returns null, which Number() read as 0 s). Adds
oversized-stream tests for OpenSky, adsb.lol, CelesTrak and TomTom that fail
on main, names the six reads in the changelog, and corrects the docs on
what was already bounded.
The flight, military and vessel feeds were named after the providers the
bundled server uses (/api/opensky, /api/adsblol/mil, /api/ais-live and
their track routes; createOpenSkySource, createAdsbLolSource,
createAisStreamSource). Any server should be able to answer a feed from
its own provider, so the feeds are now:
/api/flights /api/flights/track?icao24=
/api/military /api/military/track?hex=
/api/vessels /api/vessels/track?mmsi=
with createFlightSource, createMilitarySource and createVesselSource. The
old routes are removed. Each server names its provider in X-Feed-Source
(the bundled server sends OpenSky Network, adsb.lol and AISStream, so its
attribution is unchanged) and the military feed's cache state and age in
X-Feed-Cache and X-Feed-Age-Ms. Sources report the provider the server
names and fall back to the feed's name.
b4067f9 moved the OpenSky states/all fetch into fetchOpenSkyStates, with a
10-second limit per attempt and one retry. Keep that and drop this branch's
20-second exchange deadline; the 8 MiB body cap now reads inside the helper
under each attempt's signal. The CHANGELOG bullet moves under [Unreleased],
and CURRENT-STATE describes the per-attempt OpenSky deadline.

A stalled global snapshot held the request for over a minute. Each attempt
now gets 10 seconds, a timed-out or failed attempt is retried once, and a
second failure is answered from the stale cache or the regional fallback.
The OAuth token request gets the same limit.
The ~860 KB snapshot is held for an adaptive 9-300 s TTL and was served as
identity bytes to every request; no response in server/ set Content-Encoding or
Vary. Gzip it once per refresh beside the cached body, off the event loop, and
return the body and the header that names it together so the two can never
disagree. Live against an anonymous snapshot: 874,002 B to 258,012 B, 3.39x,
decompressing byte-identical to the uncompressed response.
Route the six proxied fetches that still buffered upstream bodies without
a limit through the shared capped readers in src/sources/httpBody.js:
FIRMS CSV, CelesTrak TLE groups, adsb.lol /v2/mil (both the OK and
relayed-status paths), TomTom flow tiles, OpenSky states/all and adsbdb
enrichment lookups. Each cap is a bound sized well above the measured
payload, not a budget.
readResponseBytesCapped gains the same optional abort signal as the text
reader, with the same cancel-on-abort plumbing and reader release, so the
TomTom tile path can share the route deadline instead of reading
arrayBuffer() unbounded. Where a route already had a deadline, the same
signal now covers the body read as well as the headers. Two polls had no
deadline at all: the adsb.lol military poll gains a 12-second one and the
OpenSky states/all exchange, including its Basic-auth retry, a 20-second
one; both miss into their existing STALE paths.
FIRMS map-key status, the OpenSky token exchange and CCTV media are left
as they are.
