Panoramax, the open federated street-level commons, registers beside
Mapillary, Google Street View and KartaView. Its meta-catalogue
(api.panoramax.xyz) is keyless and CORS-open, so it runs in the browser:
- coverage from its vector tiles: sequence lines at z11–14 below 30 km
(longest first under the per-tile cap), and above that the grid layer's
density cells as binned points, not counted as sequences;
- a click on a line opens that sequence's picture nearest the click
(STAC search, any direction), without moving the camera, then any
sequence's if it has none within 50 m; the 360° and since filters go to
the lines and to the API;
- cones from the z15 tiles' pictures layer around the open picture
(~110 bytes a picture, against ~7.5 kB for a STAC item), re-centred when
a picture opens outside them; ‹ › follow the picture's prev/next links;
- the caption names the author (not an account named by an email
address) and the picture's licence (StreetPose `license`), and links to
the picture in the Panoramax viewer; the globe credits Panoramax.
KartaView's viewer becomes the shared photoViewer.js (flat <img>, 360° on
panorama.js, ‹ ›, keyboard, pinch, context loss), driven by a per-provider
PhotoSources table; the request limiter moves to limiter.js. Panoramax shows
the 2,048 px SD derivative and fetches the HD original only when the viewer
is wide enough, once, shrunk while it decodes (never above 8,192 px).
Orange #ff6f00 (Panoramax's own), off by default, share option
0.m.0_0.r.panoramax-1. The MCP panel allows the meta-catalogue and the
biggest instances. Tests: policy, decode, source, viewer, provider, and a
Panoramax fixture in the hermetic browser gate.

From the IC8 review of #1121 (2 P2, 7 P3; each with a test that fails on
the old code):
P2
- A WebGL context lost while a newer panorama loaded left a black viewer
and a 'successful' open: the panorama now builds on the new canvas (or
falls back to its front view).
- The streaming body read every real answer takes was tested with one
chunk only: answers split mid-character are reassembled; the shared test
fake now streams, so every source test runs the production path.
P3
- Lighting another source by its chip (params) now stops a running lookup
and clears its spinner and error, as setProviderEnabled did; a restore
that changes nothing leaves them alone.
- Panoramas decode off the main thread (ImageBitmap, RGBA upload: ~90 ms →
~15 ms at 4,096 px on a phone-class CPU) and are 2,048 px docked, 4,096
once the viewer grows; a closed viewer keeps a 1×1 texture.
- The lit KARTAVIEW chip label is #8f8aff (~6:1; #635bff was 3.7:1).
- The viewer's keyboard focus ring is drawn above the photo.
- Tests: a second context loss and a drag on the new canvas; the look
direction kept across a loss; a page's 30 s first try.
- The browser gate loses a real WebGL context in the 360° step and checks
the 429 lookup was asked again (the fixture counter is reset first).

From the second IC8 pass (launch ready; P3s closed here):
- A lost WebGL context is redrawn on a new canvas (the old one only gives
back its lost context), through the core, and only if no newer photo is
opening; verified live with WEBGL_lose_context, twice.
- The 16 MB answer cap counts bytes while reading: KartaView sends
chunked answers with no Content-Length, so the header check never fired.
- A lookup gets 8 s, then 15 s once more: KartaView sometimes sits on a
lookup for 11 s and answers the same one in 3 s.
Left as follow-ups: cancelling abandoned sequence pages; finding a page
by binary search on the index when thousands of photos are missing.

A mutation review (91, then 130 mutants) found tests that could not fail
(quick presses with synchronous fakes, a no-flight check with a provider
that never posed), and untested paths. New and rewritten tests kill 123 of
130 mutants; the 7 survivors are equivalent or harmless redraws.
- viewer: held-back loads for quick presses, stale sharp/flat loads,
close mid-load, ends checks for an older photo, WebGL retried per mount,
focus handed back, look direction kept on ›.
- provider: id-ordered pages with out-of-order indexes, page and probe
failures retried, overtaken lookups, cones re-centred on ‹ ›, leftover
imagery filters hide no line or cone, coverage hints, tile cache.
- source: 429 backoff and Retry-After under mock timers, hang timeouts,
the nearest query's parameters. policy: storage-host injection, FOV 360,
longitudes past ±180. panorama: a stub WebGL context (angles, lost
context, re-measuring). lineCoverage.test.mjs: tooHigh hint, passes().
- core: openImage({frame:false}) and openNearest leave the camera
(with a posing provider and a default-open control), KartaView's legend
and wording end to end; viewerHost supportsRenderModes.
- Fixed tick-count waits replaced by an until() poll.
- Browser gate fixture: odd photos archived (409 at storage2, served by
the proxy), the first lookup rate-limited (429, Retry-After: 0); the
line-click step asserts the camera stays and › skips the archived photo.

P1s from the correctness review, each with a regression test:
- Cones showed the wrong page of a long sequence (cache keyed by
sequence; no re-centre after a close or a same-drive line click):
KartaView always reselects, and re-centres whenever a photo of the
selected sequence opens on another page.
- A 360° photo's first frame was one colour: the canvas was sized while
hidden (1×1). It is shown first, and re-measured every frame.
P2/P3s: a storage timeout or 5xx is not remembered as archived (only
403/404/409/410 are); dense z13 tiles draw up to 1,600 lines (a third of
downtown Detroit was cut); decoded tiles are kept 10 min; a timed-out tile
is asked once more; pages are 250 photos and the newest page request goes
first; a photo far past deleted ones, or unlisted at a page edge, still
finds its neighbours; a step that gets no answer is not the end; a lost
WebGL context redraws the photo, and a failed one is retried on the next
mount; the first flat image comes from the proxy (KartaView's own can be
1.7 MB); fileurl fallbacks must be https storage hosts; oversized answers
are refused; keyboard (Shift+← →, ↑ ↓, + −) and pinch look around a
panorama; focus stays in the viewer when a step button disables. Docs:
share links with 0.m.0, keyless count, CURRENT-STATE matched to the code.

Six candidates at once on photo storage (not the API host): the nearest
showable one wins. Jakarta line clicks opened 5/8 (0/5 before the QA
round; the rest are archived and say so), Detroit 8/8.

From two agentic QA passes (UX and failure modes):
- A line click opens the nearest photo that can be shown: archived photos
(409; a HEAD says 200) and records without files are skipped, a few at
most, else 'KartaView's photos here are archived'. ‹ › skip them too.
- api.kartaview.org is HTTP/1.1 (six connections): tiles take three,
lookups two, sequence pages one, so a lookup never times out behind
tiles; a timed-out lookup is asked once more; waits are capped at 10 s.
- Sequence pages follow photo ids, not the index: a photo's page is found
by search, a neighbour page joins near an edge, so ‹ › neither skip at
page edges nor loop past gaps. Pages are 500 photos (~1.2 MB).
- ‹ › open through the core without framing: loading, errors and cones
behave as for any open; presses step on from the photo on its way; the
ends disable up front.
- Cones ignore the hidden IMAGERY / SINCE filters; no 'Selected' swatch
for a source whose lines never highlight; 'no KartaView photos in view';
an unreadable tile is not cached as empty; a 0,0 fix is no photo; a
failed lookup's error goes when another source is lit; the link goes
through the image proxy; a stalled panorama shows its front view after
15 s instead of 60.

The fixture gate answers api.kartaview.org, cdn.kartaview.org and
*.openstreetcam.org from fixtures (a drive with a 360° photo, stored on
storage2 while the API names storage1) and adds three steps: keyless
coverage with its credit and hidden filters, a line click opening the
nearest photo with cones and ›, and a 360° photo on the panorama without
FIT / FILL. The Street View share-link check reads the switch field instead
of one exact entry, since a chip click records every provider's switch.
README, DATA_SOURCES, CHANGELOG and CURRENT-STATE describe KartaView.

Coverage lines from KartaView's z13-14 JSON tiles (OSM ways with photos,
chained end to start), the photo nearest a clicked line, cones along its
sequence, and a viewer for flat photos and 360° panoramas (a small WebGL
equirectangular renderer, no new dependency) with ‹ › along the sequence.
Mapillary's camera-driven line coverage and sequence cones move to the
provider-neutral core (lineCoverage.js, sequenceCones.js) with the tile
fetch, zoom ladder, colours and pick prefixes injected; Mapillary keeps
thin wrappers and its tests pass unchanged.
KartaView quirks handled: api.kartaview.org (the documented
api.openstreetcam.org serves empty tiles), photo URLs that name storage1
for photos stored elsewhere, and a photo API that answers 429 to more than
about three requests at once (two in flight, retried with backoff).

- One provider is lit at a time: lighting a chip darkens the others, and a
chip click records every registered provider's switch in one update so
the share link keeps the swap (also off Google 3D, where Street View is
not listed). The layer starts with the first default-on provider
(Mapillary, free); params that light several keep the one already on,
so reapplying them never flips (litByParams). The now-unreachable
"several lit" chip paths are gone.
- Leaving Google 3D during a Street View lookup ends it without an error
or a stuck loading state (openImage's early return resets it; the
lookup loop rechecks availability).
- A source swap during a lookup no longer reports "no imagery".
- Street View lit off Google 3D says the panel needs the Google 3D map.
- Comments trimmed to the why; keySetupCore.test.mjs back to upstream's
formatting plus the one new test (was a 551-line reformat).

- The chip reads GOOGLE STREET VIEW (and its caption link likewise).
- Providers declare the imagery filters they honour (`filters`, default
pano + since). Street View declares none: every panorama is 360° and it
draws no coverage to thin, so its lookups ignore the filters and the
panel hides IMAGERY and SINCE while it is the only lit provider.
- The legend lists only providers that draw coverage lines, with
Selected only beside one: Street View alone shows no legend.
- Providers may pick their on-globe marker (`marker`); Street View's is a
Google-blue field-of-view cone from a white-ringed dot, in place of
GEV's amber pin, and switches back for a Mapillary photo.

.scene-btn (flex: 1) loads after street-level.css and outranked the
button's flex: 0 0 auto, so with Mapillary and Street View both lit the
button shrank to its 72px minimum and its one-line label ran past the
panel edge. Scope the rule under .sl-meta-row; the coverage line wraps
instead. The live gate gives the share-link check 30 s, as the link is
written only once the view rests.

- An open after a failed one is no longer failed by the old panorama's
status: only status_changed can reject; position_changed only resolves.
- A nearest lookup aborted, timed out or refused while Google's script
loads no longer sends its getPanorama request once the script arrives.
- A panorama-details lookup that never answers times out after 10 s,
cools down and retries; an unmount releases lookups in flight, and
their late answers are dropped.
- Every Maps loader on a page shares one script load and ready callback,
and either can retry a failed script.
- OPEN STREET VIEW aimed at the sky opens nothing and says to aim at a
street, instead of looking up the camera footprint.

Conflicts with upstream's Street Level provider composition and share-state
codec, resolved:
- Street View's switch moves from its own share option (`g`) to upstream's
provider-switch field (`r`, e.g. `0.r.google-1`); a link without it keeps
Street View off. Docs and the browser gate follow.
- createApplicationStreetLevel keeps upstream's injectable provider list;
its default, once the application supplies its Street Level source, is
Mapillary plus Google Street View. Without that source there are none, as
upstream intends.
- The coverage hint keeps upstream's empty-composition message and joins
every switched-on provider's hint otherwise.
- CHANGELOG, README and SECURITY keep both sides' entries.

Review of #966: with a Google Maps key but no Mapillary token, switching
Street Level on read KEY REQUIRED / "Needs MAPILLARY_CLIENT_TOKEN" with
nothing about Street View, which stayed off (billing), so the layer looked
broken.
- While the switched-on providers lack their keys, the layer reports the
switched-off ones that would draw with a key already set
(keyAlternatives: Street View on Google 3D with a Google key). The
panel's KEY REQUIRED tooltip, its coverage line and the layer row's
tooltip then read "Needs MAPILLARY_CLIENT_TOKEN — add it in Provider
Settings, or light STREET VIEW to use your Google Maps key"
(keySetupWithAlternatives). Off Google 3D the plain KEY REQUIRED stays.
Street View stays off by default.
- OPEN STREET VIEW moves beside the coverage hint: at the default panel
width the PROVIDERS row has no room for it, so it wrapped onto a line of
its own.
- The panel gate's corner drag names what lay under the pointer when it
fails.

The Street View step's cleanup switched the Street View chip off after the
step had left Google 3D, where the chip is hidden by design. The click then
threw "failed to find element", replacing the step's real result (here, a
Google key refusal) with a selector error. Return to Google 3D first, then
switch the chips and restore the original map.
