- Google 3D: the OPEN button re-measures a ground whose tiles are still
loading (a few times, a second apart) and on a map change, not only
after the next camera move.
- Mapillary: two mounts on one host during the first download share one
build instead of leaking a second WebGL viewer.
- Retired floating-panel keys (v8 panelPos, panelFloatHintShown) are
dropped from localStorage; dead inline-position resets, the drag JSDoc
and the dead qa-ui-disposal observer branch are gone.
- Docs: z ladder, panel chrome, position storage and the fixture gate's
actual coverage; changelog fragment for #974 (old .gev-cache/mapillary
can be deleted).
- ru/es: the layer is named as everywhere else in the UI.
- Fixtures and test fakes: unused exports removed; a fake credit removal
of an absent credit no longer drops another one; the tile test reset
frees upstream slots.

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 A superseded open resolves quietly.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.

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.

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.
