Problem. Candidate M5-01 says the user-guide passage on automatic scaling of layers with different timeCodesPerSecond is 'present only at dev head bc32a65, not at the existing 363a7c8 pin'. Nature: (e) changed since. Conditions. OpenUSD releases v26.08 and v26.11.1. Method. The guide docs/user_guides/time_and_animated_values.rst at the v26.08 release tag already contains the section 'Automatic Scaling of timeCodesPerSecond' at line 298; the file at v26.11.1 also has the section anchor, so it is documented in releases, not only dev head. The behavioural claim (silent retiming on composition) is supported. Limitations. Release v26.05 and earlier not checked. Version and date. 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) M5-01 from a discovery audit; the curator re-located the cited excerpts by timed GET.

Limitations: Section text equality between v26.08 and v26.11.1 not diffed beyond the anchor match.

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