# v0.16.0 Research Navigator Validation
<a id="v0160-research-navigator-validation"></a>

## Scope

This validation record covers the v0.16.0 first-party Research Navigator release. The change adds `/research/navigator/` as one bounded discovery surface across existing repository metadata while preserving the 25 curated report bodies, report manifest, accepted glossary definitions, clean URL model, methodology/evidence boundaries, and no-third-party-runtime constraint.

## Implemented behavior checked

- `/research/navigator/` is a clean canonical public route and is present in `sitemap.xml`.
- The page exposes exactly four visibly separate result types: Reports, Topics, Glossary concepts, and Reference domains.
- Report results are derived only from report-manifest title, curated summary, and topic label metadata.
- Topic results correspond exactly to the six topic values already present in the report manifest.
- Glossary results correspond exactly to the 20 accepted glossary term routes and use accepted title/direct-definition data.
- Reference-domain results correspond exactly to the 525 normalized domains already produced by the local-only reference extractor.
- Each domain result routes to a stable deterministic fragment on `/research/references/`; the target disclosure exists and can be opened by the first-party JavaScript enhancement.
- Every Navigator result points only to an existing clean canonical local route or stable fragment.
- Matching is presentation/navigation assistance only. The Navigator does not search full report bodies, create semantic claims, rank source authority or quality, or verify external sources.
- All Navigator entries are server-rendered; native JavaScript adds multi-token filtering, type filters, live counts, and disclosure expansion without becoming content authority.

## Automated local validation

The repository-local validation pass completed successfully with:

- 106 PHP files syntax-checked with `php -l`;
- native JavaScript syntax checked with `node --check`;
- 85 canonical sitemap routes requested with HTTP 200;
- 85 unique page titles and 85 unique meta descriptions;
- self-referential canonical URLs and matching Open Graph URLs on all 85 routes;
- one parseable JSON-LD document per public route;
- 182 clean-URL/legacy redirect assertions checked;
- 151 rendered local target paths checked for successful resolution;
- 25/25 original supplied source hashes verified against the report manifest;
- 25/25 curated report hashes verified, with both stable curation/research anchors retained;
- all 25 curated report bodies verified byte-identical to v0.15.0;
- `report-manifest.json` and the accepted glossary registry verified byte-identical to v0.15.0;
- 804 extracted reference records and 525 normalized reference-domain groups retained;
- 576 Navigator entries verified: 25 reports, 6 topics, 20 glossary concepts, and 525 reference domains;
- every Navigator domain fragment verified against an existing References-page domain target;
- 194 repository-local Markdown links checked;
- 228 repository/path-pointer checks completed;
- the exact required UAIX setup/update URL retained once in each required record;
- active handoff buckets verified to contain inert placeholders only;
- prohibited-wording leakage check passed outside the owning taboo record;
- lightweight private-key/token marker scan returned no findings;
- no database runtime, external HTTP client/crawler, full-report-body Navigator index, or third-party search runtime was introduced.

## Authority preservation

The feature is derived presentation only. It does not alter the research corpus, accepted glossary definitions, research topic membership, source/curated hashes, or public legal/scientific claims. Reference-domain occurrence remains distinct from reachability, currentness, correctness, authority, endorsement, peer review, or claim support.

## External and production checks not established

This repository validation does not establish live deployment, production DNS/TLS/cache behavior, actual host rewrite behavior, webmaster-console ownership, search indexing, field Core Web Vitals, current external legal/scientific state, external reference reachability, or independently verifiable machine-execution provenance. No live deployment was performed.

## Packaging note

The release is packaged for direct web-root extraction. A clean extraction of the release archive is re-run as part of the final handoff after this durable report is written; the final archive SHA-256 is supplied with the handoff rather than embedded here so recording the hash does not mutate the archive it describes.
