Partially verified: the curator re-read S33, S35; S34, S36 were not re-read by the curator and rest on the producer's pinned reading. WCAG 2.2 requires captions for prerecorded audio in synchronized media at Level A (except clearly labelled media alternatives for text) and sign language interpretation only at AAA; WAI notes most policies do not require sign language, judges sign-language avatars not adequate, and advises placing the signer (usually bottom right, above tickers) with a visible toggle. These are content criteria, not legal duties.

Curator qualifications: Partially verified: the curator re-read S33, S35; S34, S36 were not re-read by the curator and rest on the producer's pinned reading. Curator GET 2026-10-23 of the sources not re-read (mechanical source evidence, not semantic verification): S34: HTTP 200, bytes equal to the producer pin; S36: HTTP 200, bytes equal to the producer pin. Documents read 2026-10-22; no bag created or validated. SC 2.1.1 keyboard text and Understanding pages (S34, S36) not re-read.

Limitations: Documents read 2026-10-22; no bag created or validated.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
