## Scope

Validation for the v0.6.0 integration of the generated homepage hero image into the existing MachineIntelligences.org repository. This was a repository-local implementation and packaging check; no live deployment was performed.

## Changed surface

- Added `assets/images/home/machine-intelligence-home-hero.png` (1672×941 source hero).
- Added `assets/images/home/machine-intelligence-home-hero.webp` (delivery derivative).
- Updated `index.php` to render the hero with `<picture>`, accessible alternative text, high fetch priority, and a visible caption while retaining the existing HTML H1/lede/direct-answer content.
- Updated homepage Open Graph/Twitter/structured primary image metadata.
- Updated `sitemap.xml` to expose the new homepage image.
- Added responsive hero-media styling to `assets/css/site.css`.
- Updated release memory, architecture, decisions, progress, README, implementation history, and test/package guidance to v0.6.0.

## Validation results

- **PHP syntax:** all 15 PHP files passed `php -l`.
- **Route smoke:** all 13 public routes returned HTTP 200 locally and retained exactly one H1.
- **Rendered local targets:** 51 root-relative links/assets discovered from rendered pages resolved successfully.
- **Metadata:** homepage `og:image`, `twitter:image`, and JSON-LD `primaryImageOfPage` resolve to the new PNG.
- **Hero delivery:** PNG opens at 1672×941; WebP derivative opens at the same dimensions.
- **Hero source SHA-256:** `75dc372e576d079a79d785ed0a430c3daa03b222f7c709156c08f67cf636edb3`.
- **Hero WebP SHA-256:** `335b37cdf16c99f62a78ad44edd2159909a53719724192111673b7145fd0df78`.
- **Sitemap:** valid XML with 13 public URLs and 7 image entries; the homepage hero is present.
- **Structured data:** JSON-LD parsed on all public routes checked.
- **Favicon:** existing first-party ICO remained readable after the change.
- **Research preservation:** all 19 curated report SHA-256 values still match `research/report-manifest.json`; required curation and research-body anchors remain present.
- **UAIX:** required current records remain loadable; package/current-memory version is 0.6.0 where applicable; the exact wizard update URL remains unchanged in `AGENTS.md`, `.uai/readme.human`, and `.uai/agent-pickup.uai`.
- **Durable links:** current changed memory/docs relative paths resolve; new v0.6.0 history and validation pointers are present.
- **File handoff:** Content and Improvement intake remain inert/empty except permitted placeholders.
- **Secret hygiene:** text/code scan found no candidate raw API keys or private-key blocks.
- **Git:** unavailable in supplied archive; no `.git` metadata exists to inspect.

## Residual risk / skipped checks

- No real-browser screenshot regression, Lighthouse/Core Web Vitals, production CDN/cache measurement, Search Console/Bing Webmaster inspection, or live crawler/indexing verification was available.
- The hero contains embedded visual text, so the page intentionally retains equivalent visible HTML semantics; future visual edits should preserve that boundary.
- Production DNS, TLS, redirects, host PHP/runtime configuration, and actual deployment state remain unverified.

## Completion gate

Repository-local implementation checks pass. No third-party runtime dependency was introduced, no research report substance was changed, no raw credential was copied, and no live deployment occurred.
