SCVeamer version 1.4 prototype: original validation record
2026-10-24

This file records checks performed when the supplied 1.4 prototype was prepared,
before the publication-documentation revision. See VALIDATION_PUBLICATION_1_4.txt
for the documentation update and the later report of practical use on Windows 11.
The original record below and measurements under validation/ remain records of
their respective test dates. Their untested-Windows statements are not claims
that the later personal-use report did not occur. No new runtime test is claimed
for this documentation-only publication preparation.

====================================

SCVeamer version 1.4 prototype validation — 2026-10-24 (Japan time)
Build: 1.4-prototype-20261024

Baseline: the accepted PDFium 2560px prototype derived from public SCVeamer1.3.
This record distinguishes the versioned-kit checks from the preceding backend
comparison in VALIDATION_PDFIUM.txt and the original JSON records in validation/.

Final versioned-kit checks: PASS
- Rebuilt all three projects in each edition through the PDF-only path.
- Python regression suite:17 tests pass in each edition, without fitz/pymupdf.
- CLI --version reports SCVeamer1.4 prototype /1.4-prototype-20261024.
- Every generated HTML file is byte-identical to its accepted predecessor after
  normalizing ONLY3 outer product-version labels and1 scveamer_version value.
- All196 embedded page/print-fallback PNG states are byte-identical in total.
- All remaining JSON payload, titles, alternative text, game sources/settings,
  language, timings, overlays and print fallback are unchanged.
- HTML format remains holomorphonautica-talk-template-2.0.
- Each edition's player JavaScript/CSS and6 game/catalog files are byte-identical.
- Each edition's25 input/configuration/TeX/style/PDF assets are byte-identical.
- All4 regenerated handout files (104 pages total) are byte-identical.
- Each edition's20 license texts, inventory and third-party notices are identical.
- Current code changes relative to the accepted prototype are limited to product
  version strings, settings/fallback namespace, recipe comment and test fixture.
- Current documentation was checked for correct1.4/baseline1.3 labels and scope.

The user accepted the appearance of the2560px presentation on2026-10-24.
Their response does not identify an OS, screen size, zoom or projector.

The earlier offline browser run passed103 checks per condition. It was not
repeated just for version labels; full-file equality proves the actual HTML
change is limited to those four product-version values. The preceding benchmark
and memory figures retain their original single-run measurement scope.

Current application and HTML product labels are1.4. Historical release notes,
PDF source content and unchanged source comments retain original version labels.
Settings/fallback namespace: version-1.4-prototype-en.
Bundled image width2560; CLI > presentation.json > fallback1920.

Not tested: fresh Windows/Mac GUI operation or setup, executable creation,
full TeX compilation workflow, live projection and arbitrary-PDF compatibility.
No new legal/organizational clearance, security audit or own-code MIT grant.
The public site and original download archives remain unchanged.

Detailed measured files and hashes: validation/v1_4_release.json.
The ZIP carries PACKAGE_MANIFEST.json with the size/SHA-256 of each other member;
archive integrity is checked at delivery, and its final hash is in the handoff.
