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.
