# Source index

Research date: 22 October 2026. Source cards retain provenance and bounded paraphrases. Full third-party webpages are not mirrored. Internal JSON evidence is frozen separately with checksums.

[Machine-readable register](2026-10-22-source-register.json) · [CSV index](2026-10-22-source-index.csv)

## Method and limitations

- Primary sources were opened and relevant sections read after discovery. Search snippets alone do not substantiate included claims.
- Documentation establishes documented behavior, vendor price lists establish dated list prices, and company/partner pages establish attributed public descriptions. None establishes Knauf economics.
- Publication and update dates are retained where established. Unknown dates remain null. Access date is not publication date.
- IDs are unique source records, not unique studies. A repeated URL across workstreams is the same underlying evidence.
- Research findings, recommendations, synthetic arithmetic and measured internal results are labelled separately.
- Recheck mutable provider terms and official pages before final delivery. Keep this dated snapshot when creating a later one.

## Supplemental skill audit

The later [adoption snapshot](agent-presentation-skills/2026-10-22-adoption-audit.json) and selection memo [local reference omitted] supersede the initial A01-A11 recommendations. Their additional links are recorded in that separate snapshot rather than being counted as independent evidence in the original 78-record register.
