# Executed validation — 2026.09.09

## New utility tests

All 24 unit tests passed locally. Exact output is in [unit-tests.txt](unit-tests.txt). Tests exercise the four new utilities, including deliberately invalid inputs; they do not execute the preserved original script or legacy code examples.

## Release integrity

The [library audit result](library-audit.json) reports the final tested file counts and errors. It checks declared local Markdown file targets, release JSON syntax, catalog source references and SHA-256 preservation of all 146 unique originals. Historical text is not altered merely to make its old links pass.

The check does not test external URL availability, Markdown fragment anchors, factual entailment, live indexing, application execution or rich-result eligibility.

## Browser behavior

The [browser QA result](browser-qa.json) records nine passed checks: initial report display, current/all/legacy filters, title search, internal navigation, full-text search, legacy warnings, portable-report source links and narrow-screen layout. There were no JavaScript errors or external HTTP(S) requests in the tested interactions.

The environment blocked direct file-URL navigation. The generated HTML was therefore loaded into Chromium using Playwright `set_content`; direct launch from the local filesystem was not tested here. The browser uses embedded document data, no fetch-based document loading and no required remote fonts or scripts. Keeping the extracted folder intact is necessary for links to raw companion files.

## Manifest scope

`SHA256SUMS.txt` records final release-file hashes except its own. It is a change-detection aid, not a signed authenticity assertion. The original upload's hash and release inventory counts are in `Research/release-manifest.json`. No production website or external account was changed.
