Without a limit parameter the route read null, Number(null) is 0, and the
clamp turned that into a one-feature list. An absent or empty limit now
gets the documented default of 500.
The voice answer waited 25 s for /api/osm/features, while the server let
Overpass run for 25 s and itself waited up to 40 s per endpoint and 45 s
in all. When the browser gave up first it closed the request, the route
cancelled the upstream query, and nothing was cached, so the OSM_TIMEOUT
retry started the same query from scratch and timed out again.
The server now tells Overpass 20 s, waits 22 s per endpoint and 22 s in
all, which ends inside the client's 25 s. A test pins that ordering.
From review:
- /api/osm/features now refuses cross-site browser requests like the other
quota-bearing routes, so a page elsewhere cannot spend the operator's
Overpass. SECURITY.md lists the route, its limits and its disk cache.
- One client runs one search at a time and two run at once in all, instead
of one global slot any single client could hold.
- A search gets 45 s across every configured endpoint in turn, answered 504
when it runs out.
- A cache write no longer waits on the disk prune; prune() waits until the
cache is idle for callers that need it.
The /api/osm/features cache key was the query alone, kept for a day, so after
an operator repointed OVERPASS_UPSTREAMS the old instance's answers were still
served. The key now includes the configured-upstream tag, as main's other
Overpass caches check it, so a new instance is always asked.
Both stack parents (#837, #842) are on main, so the voice geometry branch
now builds on main directly. Conflict resolutions keep main's behaviour and
add the geometry work on top: osm_query gating on every provider, restored
admin identity for Nominatim outlines, merged analyst follow-up memory, and
the cancelled Globe View reset instruction ahead of the generic cancellation.
- fmtArr prints reveal-err and flags an angle violation on a timeout result.
- Regression: a late hidden reveal frame records no angle and stays retryable.
- README/SECURITY: $host drops a non-default port, so recommend $http_host.
- requestAdmission tests: say why a new admission test must use freshClock.
- observeArrivalRotation reads the sample before the deadline check and keeps
a late frame's angle on the timeout result; arrivalAngleViolated then makes
it final. Regressions: wrong late reveal and wrong late settle, each followed
by a clean second attempt, still fail; a clean late frame stays retryable.
- Overpass admission tests: a monotonic per-test clock removes order
dependence on the module-level limiters; the proxy test covers ::1 and
::ffff:127.0.0.1 sockets; a new test pins the proxied: upstream bucket.
- Retry edges (wrong on-time reveal, maxAttempts, inclusive 10° limit) and a
check that every name the track harness imports is exported.
- Docs: nginx needs Host, X-Forwarded-Proto and X-Forwarded-For; Docker bridge
networking makes every host client one remote peer; list the exact
forwarding headers; owner misses can also see 503.
- /api/overpass: a loopback socket with forwarding headers (a local reverse
proxy) is admitted from the remote pool under a socket-keyed proxied: bucket,
never the owner's direct-loopback window; the upstream limiter uses the same
key. Regression: owner cache hits survive an exhausted proxy bucket.
- Arrival check: a reveal timeout keeps the settle angle it measured; the new
observeArrivalRotationWithRetry retries only inconclusive timeouts, so a
real violation cannot be retried into a pass. Regression: wrong settle angle
-> reveal timeout -> clean second attempt still fails.
- SECURITY.md, README, changelog and CURRENT-STATE: scope the guarantee to
admission isolation, name the forwarding headers a local proxy must send,
and state that the upstream budget stays shared.
A caller that joins a cold reservation no longer inherits another client's
RATE_LIMITED result. Once the rejected reservation is released it retries:
it either owns the next reservation and is admitted on its own quota, or joins
an admitted fetch. Adds a two-client regression (exhausted owner, available
joiner, exhausted joiner coalescing onto the admitted fetch).
Also drops the duplicate memory publication for a disk hit in the handler;
preflight already sets it, the handler only trims.

Address gekh's review of 69a87fe2:
- P1: /api/overpass now uses admitSameSiteKeyless, like /api/terrain/heights,
so an instance behind the README's reverse proxy keeps its Overpass-backed
layers; cross-site shapes are still refused and forwarding headers no
longer launder them. SECURITY.md, the gate header and CURRENT-STATE say so.
- P2: admission keys IPv6 peers by /64 and folds IPv4-mapped peers
(clientNetworkKey), and loopback has its own 300/min window outside the
900/min global, so a few LAN peers cannot lock the owner's browser out.
- P2 (track): the settle and reveal frames each get their own 500 ms budget,
measured from moveEnd and from the settle frame respectively, so a ~300 ms
SwiftShader frame no longer trips the reveal deadline while both stay
inside the 1 s idle refresh.
- Smaller: drop the dead settings-block check and stale probe comment in
query.js, clamp whitespace-tolerant [ timeout : N ], and add tests for the
global window, the /64 keying, loopback headroom, proxied admission and
cache hits spending admission but not upstream budget.

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.
- turn named places and mapped landmarks into reusable bounded areas
- count loaded records inside resolved, drawn and annotated geometry
- find recent imagery for an area, the view or the pointer snapshot
- keep osm place search behind an operator-configured overpass endpoint
- preserve cancellation, ownership and follow-up memory across every action
- cover geometry, provider lifecycle, cache isolation and voice routing
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.
