General structural audit for a local web/app repo: counts, missing local asset refs, and a clean JSON report.
Finds app roots and verifies required thumbnail/hero assets; can optionally copy a template thumb to fill gaps.
Sorts a tiles/modules JSON file by a chosen key and optionally applies the change in-place.
Checks for a Nexus bar marker across HTML pages and can inject a minimal Back-to-Nexus bar when missing.
Scans HTML/Markdown for placeholder meta/text and can apply safe replacement rules.
Validates app folders against required files (index.html, etc.) and reports missing components.
Runs lightweight JS checks (node --check) or grep-based sanity scans and produces a failure report.
Finds settings.json files and reports drift; can sync all copies to a chosen source.
Validates ZIP integrity and lists entries (bounded) into a receipts-friendly report.
Runs a controlled set of safe autofixes (meta cleanup, optional nexus bar injection, 404 stub creation).
Checks cross-link integrity in HTML (relative href/src) and reports broken local links.
Builds a reachable-page graph from an entry HTML, flags missing targets and orphan pages.
Generates a launcher.html linking to discovered app index.html entry points.
Creates missing stubs (404.html, README.md) per app root and logs what it generated.
Runs a basic Playwright smoke flow against controlled demo targets and saves screenshot receipts.
