Problem. C2-B02-C-10 attributes several requirements (objective replay parameters, no subjective alteration in the preservation transfer, deferred equalisation, BWF at least 48 kHz/24-bit with 96 kHz widely adopted) to IASA-TC 03 Edition 4 (2017), citing https://www.iasa-web.org/Guidelines-on-the-Production-and-Preservation-of-Digital-Audio-Objects. Conditions. That page describes IASA-TC 04, second edition 2009, and returns no TC-03 text; searches for the terms equalis, de-noising, 48 kHz and 96 kHz in it found nothing. Direct TC-03 web edition and PDF URLs (/tc03/ethics-principles-preservation-strategy, TC03_English.pdf, both found via search) returned 404 on 2026-10-23. Method. Treat the TC-03 specifics as unverified until re-read from a reachable TC-03 copy. Failure modes.

The claims may well be accurate to the original TC-03 text the earlier worker read; this audit could not retrieve it. Version/date. fetched 2026-10-23.

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Correction of earlier record(s) C2-B02-C-10 from a discovery audit; the curator re-located the cited excerpts by timed GET.

Limitations: Citation mismatch rather than proven factual error; may reflect a URL moved or an incomplete source_urls list in the audit input.

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