Image loading (photoViewer.js)
- One AbortController per open: a new open, close or unmount stops the
previous photo's first and sharper downloads (an <img> by src = '').
A collapsed viewer never falls back to the original; Panoramax's flat
fallback is the thumbnail. A superseded open resolves quietly.
- Flat HD tracked as "loading" and "shown" apart: a discarded response no
longer blocks later upgrades, and resizes while it loads ask once.
- No upgrade of the photo still shown while another opens.
- Size limits before decoding: imageSize.js reads JPEG/PNG/WebP/GIF
headers; more than 64 MP or 16,384 px a side is refused undecoded, an
<img> that decodes larger is refused and let go, flat HD needs a known
width of at most 8,192 px, and panoramas always decode with a resize.
Panoramax provider
- Retry-After parsed as seconds or an HTTP date; the browser cannot read
it here, so busy answers back off 5 s doubling to 300 s, reset once
answered.
- Headers timed, then the body by an idle timeout (15 s of silence), so a
slow link still gets its megabyte tiles.
- Cones centre only on the picture shown (onShowing), never on a late
lookup; lookups nobody waits for are aborted (shared, refcounted).
- onReopen: a GPU reset redraws in the viewer, not through the core.
- Cones draw the home z15 tile at once and add neighbours as they arrive;
a neighbour that failed is not counted as drawn.
- Coverage tiles decode in ~8 ms slices (a 2 MB z10 tile over Paris was
one ~85-200 ms task); sorted by measured length without a Map.
- Box search asks for 20, not 100 (the API returns them nearest first).
- looksLikeEmail checks every '@'; creatorOf de-duplicates with a Set.
lineCoverage.js
- A redraw while a swap still builds keeps what is on screen (the swap's
old lines and its ready new ones) and drops only the unready ones.
Tests for each (mutation-checked), two vacuous tests made real, the
cones' pictures lane and readable()'s busy/timeout paths covered; the
fixture's box search is nearest first. Docs: README filters and share
links, CHANGELOG HD wording, CURRENT-STATE.

KartaView's later viewer changes are carried into the shared
photoViewer.js: the camera bearing (`bearingOf`), redrawing the same
photo after a GPU reset through `onReopen`, no pose while a lost context
recovers, the 2,560 px flat version only once the viewer outgrows
1,280 px, `refreshPose`, and one sharper-panorama load at a time with a
second look once it lands. Its tile cache's `keyOf` and `clear` move to
the shared tileCache.js. KartaView gets `onEscape` beside `onReopen`.

From a five-lens IC8 review (correctness, security, tests with mutation
testing, performance, UX):
- P0: over Paris at 12–60 km the unsimplified z10–z12 lines sent ~2M
points to Cesium's ground-polyline builder (gigabytes of geometry; the
tab hung). decode.js now simplifies lines (Douglas–Peucker, 4 tile
units: 6–10% of the points), and lineCoverage gains an opt-in point
budget (`maxPoints`, 10,000 a tile for Panoramax).
- Decoded coverage tiles are kept (KartaView's tile cache moves to the
shared tileCache.js); a sequence's z15 picture lists are kept and load
on their own connection; cones know their tiles from the start of a
load, so a picture opening meanwhile re-centres them and ‹ › no longer
restarts the load.
- The HD panorama loads only for the expanded viewer (a docked one on a
dense screen asked for 3 MB originals) and is aborted when another
photo opens; picture files over 48 MB or 16,384 px are refused; a
bitmap no renderer took after a context loss is closed.
- A nearest lookup survives one of its two searches failing; only a
timeout is retried; offline reads as unreachable; Retry-After is
capped at five minutes; the search box stays on the map at ±180°;
cones near both edges of a narrow (high-latitude) tile read both.
- Every producer is credited (app and photographer); with none to name,
the caption says "via <instance>" rather than crediting the host.
- Esc anywhere in the docked viewer (toolbar, caption) clears the
sequence before the panel takes it. A filter that hides every density
dot says so; wording aligned ("coverage", "photo").
- Tests for every surviving mutant (Esc consumed, keepOrder and dot-size
wiring, licence in the core, limiter aborts, radius floor, bbox corner,
first-producer-only, byte and size caps), a limiter test, and a gate
fixture that answers box searches and leaves out pictures facing away;
the gate now clicks over the other sequence's pictures, so only the
line click's own-sequence lookup can pass.

KartaView filters coverage on its server only in its PNG tiles (its JSON
tiles come back empty with a filter), so a filtered tile's PNG is a mask
over the cached JSON segments: a segment stays when at least half the
points along it lie on drawn pixels. A filter change reloads the lines
(lineCoverage.reload keeps the drawn ones until the new ones are in);
masks are cached per filter and tile, and a filtered tile KartaView is
still drawing (504 or a timeout) is asked again, four tries in all.
The nearest lookup asks the photo API for the projection and date, and
the cones follow the filter like Mapillary's. The gate fixture draws
filtered PNG tiles and adds an older flat-only street; a new gate step
checks 360 and LAST YEAR thin KartaView's lines and ALL brings them back.

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.

Marker and direction (reported on the PR):
- KartaView has its own marker, a purple view cone (Street View's is
blue), not GEV's default pin that Mapillary uses.
- The camera direction (marker, cones, FOLLOW, a panorama's centre) is
the direction of travel to the next photo a few metres on. KartaView's
heading is the device compass: whole drives read 0 (no compass) and
others sit a steady ~110° off. Until the drive loads the compass stands
in (0 = unknown), and the pose is sent again once the course is known.
Remaining P4s from the review of #1121:
- Segment chaining is linear (a per-point cursor) and capped at 20,000
segments a tile and 5,000 points a line: a hostile tile of 60k segments
sharing one point took 1.5 s, now tens of ms.
- Decoded tiles are dropped when KartaView is switched off.
- No network / a refused request says so and is not retried as a timeout;
an unreadable answer says so.
- A docked flat photo skips the 2,560 px download until the viewer grows.
- The panel counts the drive's photos (countActivePhotos), not the thinned
page of cones (2,250, not 217).
- After a GPU reset the viewer redraws the photo itself, so a lookup the
user started is not cancelled; a failure is still reported.
- The gate's keyless page lights KartaView and checks it draws with no key;
the fixture answers the sequence count; the line-click step checks the
camera looks along the drive when the compass says 200°.
- README/CHANGELOG show the share-link form the app writes.

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).

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.

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.

Trim the doc text this PR adds (README, CHANGELOG, CURRENT-STATE,
KNOWN-ISSUES, SECURITY, DATA_SOURCES, .env.example, the CI job comment),
drop code comments that restate the code, cut design-note JSDoc to a line
or two, and drop review tags from test names. Comments only; no code
changes.
Also: README key count (seven keys, two metered), CURRENT-STATE's gate
paragraph (CI runs a production build with a dummy token), the stacked
doc above meshBoxInRange and the orphaned inMeshRange line in
coverage.js, and a duplicate ALPR row in DATA_SOURCES that a merge had
brought back.

- The CI gate builds the app and serves it with `vite preview`, with a
dummy non-secret client token (a fork PR never gets secrets), and
answers the Graph API, image tiles and thumbnails from fixtures: 41
photos on a line under the parked camera and one generated 640x320 JPEG
(scripts/fixtures/street-level). All 7 photo steps now run in CI, plus a
real click on a coverage line and on a cone, the framing flight stopping
on close, the inert modal, the viewer returning into the panel, and a
reload keeping a collapsed panel collapsed (share ui token t).
- Fixture interception is limited to Mapillary hosts via CDP
Fetch.enable: page-wide request interception stalled Cesium's workers,
so the old fixture mode never drew anything on the globe.
- Failure evidence (screenshots, UI state, console, failed requests,
render errors) is written to qa-artifacts/ with keys and tokens redacted
and uploaded on failure; qa-artifacts/ is gitignored.
- Cesium render-loop errors fail the gate; Google 3D branches that cannot
run print as skips, and --strict rejects any other skip.
- Panel presses log their diagnostics, warn on a retry, and CI now fails
on any retry (QA_FAIL_ON_RETRY=1) since the rail settles; a press with
no pointerdown is a failure, not a retry.
- Assertion-gating sleeps 27 -> 1; the rejected-key "no requests" check
has a positive control.
Verified locally: strict fixture gate on the production build 28 ok + 2
"no Google 3D" skips (twice, fail-on-retry on); panel gate 5/5 plus no
render errors; live gate with a real token 25 ok + 3 fixture-only skips.
