From gekh's review of #768, each bug with a test that fails before:
- P2: a failed sequence load clears the previous sequence's cones, resets
the selection and can be retried; a second click while loading starts no
second lookup. sequences.js had no tests: sequences.test.mjs now covers
failure and retry, a superseded late answer, the cache and clearSelection.
- P2: closing a photo stops MapillaryJS sequence playback, which kept the
hidden viewer stepping and downloading images.
- openNearest without the panel reports it instead of loading forever, and
stops if the layer (or its provider) went off during the lookup; the
mesh sampler's misses are bounded and forgotten with its samples; the
sequence count is the union of ids across tiles; a provider withdraws
only its own error, so a sequence error cannot mask KEY REJECTED; hover
stays on (throttled) under an orbiting camera and re-picks when it
stops; "since N days" follows the clock in a long-open tab.
- A prewarm waits for one in flight and then builds if it gave up.
- New coverage for the layer core (credits, KEY REJECTED vs REQUIRED,
switching a provider off), the refresh wiring of the tilted-view fix and
the draped-to-cast swap completion.
- Cleanup: loading is derived from pending; freshStreet(); tile ranking
computes distances once and shares one path for the date line; shared
metresBetween / whenIdle / redrawTile; one NEAREST_RADIUS_M and one
source method list; unused contract fields, exports, getImage and the
decoder's image branch removed; PROVIDER_COLORS lists only Mapillary.
