The probe shipped with no tests while every sibling research script has them,
and it needs neither a model nor a GPU, so nothing justified the gap. Its whole
output is a ranking and a mispaired comparison still prints a plausible number,
so the pairing tests carry more weight than the metric ones.
The centerpiece builds a correctly phased and a wrong-phased delivery of the
same clip. Both have six frames, so the frame-count check the probe used to rely
on passes for both; the misaligned one scores near 9 dB against 40+. A separate
assertion pins that the probe binds the engine's sampler rather than a copy,
which is the contract a same-phase private copy would otherwise satisfy
silently. This file now holds the only constraint on that sampler's phase.
CI ran none of this. The test matrix installs no ffmpeg, and the job that does
install it ran one class from another file, so five of these tests would have
skipped on every runner. The video-e2e job now collects this file too.
Recorded in .claude/rules/development.md: mutating the sampler's >= to > proves
nothing, because the 1e-9 epsilon makes both branches agree on exact equality.
The phase or the period is what has to move. That inert mutation passed a green
suite here before the real one failed five tests.
Dropped the downscale test's PSNR bound: solid colors survive both the downscale
and the upscale exactly, so any score there pins the local ffmpeg's chroma
rounding rather than the probe. Geometry is the assertion that means something.

* Add cross-platform CI test matrix, PyPI classifiers
CI: new test.yml runs lint (ubuntu) + a test matrix (ubuntu/macos/windows
x py3.10/3.12, core+dev, GPU tests skip) on push to main and PRs, closing the
gap where only the release publish.yml ran (ubuntu, no tests). Add PyPI
classifiers (OS/Python/topic). README Tests badge, CLAUDE.md CI note.

* Make availability tests reflect installed deps, not assume gpu extra
The new core+dev CI matrix has no diffusers, so the invisible-engine
availability tests (asserting is_available() is True unconditionally) and the
two mocked invisible CLI tests (whose command gates on is_available before the
mock) failed. Assert availability == actual importability of torch+diffusers,
and patch the CLI availability gate so the mocked-engine tests run regardless of
the gpu extra.
