[grant-mccurdy]

Summary

• route README review links to the canonical Demos and Content RAG surfaces
• regenerate the citation-ready RAG index and vector export
• refresh the information-object map and public-safety review

Portfolio impact

The public Content Intelligence repository and the portfolio demo now describe and serve the same 92-record reviewed corpus.

Public readiness

Generated records retain source IDs, citations, checksums, and public-safety metadata. The corpus contains synthetic, sanitized, public-domain, or permission-safe material only; no credentials or private records were detected.

Reviewed the exact five-file patch and passing Quality check. The 92-record index/vector export is internally consistent, citation and safety metadata are retained, canonical demo links resolve, and no credential-like values or private records are present.
