overpassLooksRuntimeError and overpassLooksRateLimited searched the whole
200 body, element tags included. A result containing a place named
"Timed Out Escape Rooms" (or any tag with "runtime error", "out of
memory", "too many requests" or "rate_limited") was refused as an
upstream failure, and the endpoint was put on cooldown for every other
query.
Parse the body once. A data reply (one with an elements array) reports
failure in its remark, so the phrase checks run on the remark. Any other
body, an error page or JSON without elements, is matched whole as
before.
Uses a full SHA-256 of the sorted instance list, so reordering the same
instances for failover keeps the cache. Adds the installation-cache repoint
test (tagged, reordered, repointed, untagged, unconfigured) and the changelog
and current-state notes.
Both disk caches fed by OVERPASS_UPSTREAMS key only on the query — the Overpass
proxy on the sanitized request body, the installations proxy on the bbox — so an
entry written against one instance is a hit for the same query against another.
After an operator repoints OVERPASS_UPSTREAMS, the previous upstream's answers
keep being served for 7 days, 30 for boundary-class queries, and indefinitely
through the serve-stale path. An install that predates #742 has a cache written
from the public instances that were the default then, and configuring your own
instance does not displace it.
Cached answers now carry a tag identifying the configured upstream set, and a
disk read refuses an entry that does not match it, on the stale path too. With
nothing configured any entry is still accepted: there is no instance to
contradict, and serving last-good data at any age is what the not-configured
path exists for. The tag is a hash of the resolved endpoint list, never the
URLs; it is written to disk and compared on read, and is not sent to clients or
surfaced in errors.
One line is logged once per process when a foreign entry is ignored, naming the
variable and what will happen, as local-receivers.js already does for a
rejected feed.
Cost worth naming: on upgrade every existing entry is untagged, so the first
outage after upgrading serves nothing where it previously served stale data,
until each query is fetched once from the configured instance.
Traffic roads come from OpenFreeMap vector tiles, or TomTom flow tiles with a
key (Hybrid by default). Military areas use OpenFreeMap polygons with a bundled
worldwide name index; wide views show named points. ALPR reads an hourly
OpenStreetMap extract. Cockpit place context and country, state and US county
outlines use bundled Natural Earth and US Census data. Overpass is used only
when an operator configures their own endpoint.
Also: camera arrivals no longer land below ground, keyless terrain retries on
429, bounded relation geometry for configured Overpass, one shared
OpenStreetMap credit, and separate tile and API transports for embedders.

Supersedes #420 by @GladiatorrX9, ported onto the current component layout with fixes from review.
Verified before merge: format, package boundaries, unit suite, build, and the browser tracking suite; a browser harness for the change where one applies; adversarial review applied.
