SCVeamer version 1.2 — historical validation record, translated summary
2026-10-23

Environment: Python 3.12.14, PyMuPDF 1.26.6, TeX Live 2023 (LuaHBTeX), Chromium.
Native Windows 11, Edge/Firefox, actual projector hardware and executable builds
were not tested in that preparation environment.

Source builds:
- Then-current Japanese sample: 41 slides, 67 display states, 120 minutes;
  TeX→PDF→HTML, existingPDF→HTML and 41-page handout generated.
- Starter: 6 slides, 9 display states, 6-page handout.
- Template v2: 9 slides, 13 display states.
- Sources without a start time showed no planned clock.
- Overlays were grouped for ordinary and interactive frames.

Display and interaction:
- The sample's 67 PDF pages matched earlier source typesetting outside the footer.
- No speaker-note data/button/guide in the notes-disabled sample.
- Eight fixed-example IDs and scheduled times checked.
- Circle-test surfaces used 90% opacity in WebGL and Canvas2D.
- Open/close circle controls, answers, counterexamples, reset and back-to-question
  were checked on std-b02. Rotation/circle state survived slide navigation.
- Keyboard navigation, contents, F2 focus switching and scheduled time handling
  were checked, including fractional minutes and midnight rollover.
- Toolbar layouts checked at 1280×900, 800×600 and 600×800.
- Standalone player 12 checks and lecture HTML 27 checks passed without page
  JavaScript errors or external network requests during offline use.

Regression and documentation:
- 15 automated checks passed: overlays, hidden footer, schedule validation,
  missing durations, TeX priority, optional notes, legacy compatibility,
  --no-plan independence, previous-output preservation, handout links,
  versioned settings and CLI saved/explicit options.
- LuaLaTeX and pdfLaTeX test sources compiled.
- Major document links, anchors, 194-example search/copy catalog and credits checked.
- ZIP integrity and bundled outputs checked; caches, settings, workspaces,
  virtual environments and temporary outputs excluded.
