66.1 Gallery runner🔗ℹ

The default directory is slides-output/gallery. The runner writes an HTML index, posters, sampled PNG strips, a manifest, and reusable storyboard sources. It makes a sibling ZIP unless disabled. Videos are optional.

An explicit entry/category combination must agree. Unknown IDs are errors. The current catalogue has 42 entries; use –list rather than assuming that a name is present in an older installation.

Geometry videos use the module-backed project path and honor the requested worker capacity. The console and manifest report actual worker starts. The number requested is not proof that that many workers did useful work. The gallery’s repeat check is not the Pict/Scene comparison performed by the separate probe runner.

66.2 Visual probe runner🔗ℹ

The default directory is slides-output/probes. Options are –repeat N (default 2), –gallery, –math, –geometry, and –no-zip. There is no –workers option on this tool. A probe review is not a measurement of subprocess rendering performance.

The base run covers the built-in layouts in both themes and four formats, plus selected ordinary examples. –gallery adds gallery samples in light/dark and wide/portrait formats. Math and geometry flags enable their optional examples. Samples include boundaries and interior times, in reverse seek order.

Each comparison produces a -pict.png and -scene.png. The runner checks that repeat renders within each path have identical pixel bytes. It separately compares the two rendering paths, which may differ at antialiased edges.

66.3 Files and transcript scope🔗ℹ

index.html shows paired pictures and links to stdout.txt and stderr.txt. The runner still writes to the terminal. Logging starts after argument validation and output-directory creation, so errors before that point are not recorded there. The logs contain output sent through the runner’s Racket output/error ports; this is not a general operating-system transcript of every possible child-process file descriptor.

On normal completion, the runner prints its summary, flushes the logs, and then creates the ZIP. Thus the ZIP contains those transcripts through the summary. ZIP-creation failures cannot be recorded inside a successfully completed ZIP that does not exist.

66.4 Manifest fields🔗ℹ

The probe manifest is JSON with this schema label: animate-slides-probes-v3. It records:

The threshold uses raw 8-bit channel units, on a 0–255 scale. It is not 10 percent and not a geometric distance in pixels. A mean difference above 0.10 fails the comparison. A nonzero maximum difference alone does not fail it. Inspect a reported failure before changing the tolerance.

The runner exits with status 0 when its recorded errors list is empty and 1 otherwise. Earlier fatal setup errors can stop it before a manifest exists. No probe count or absence of errors proves that a lesson is well designed.

66.5 Test runner🔗ℹ

Without flags, the runner selects its base suites. The flags add the relevant integration suites, including real external tools and worker paths. Use the reported suite results as evidence for the installation you actually tested. Do not infer a pass count from a release label in this manual.
