Problem. Candidate M2-03 says OpenUSD's tested OpenVDB, 10.1.0, is from the MPL era. Nature: (e) changed since. Conditions. OpenUSD v26.11.1 or later. Method. At tag v26.11.1 VERSIONS.md lists OpenVDB 12.1.1 and build_usd.py downloads v12.1.1; at v26.08 both said 10.1.0. The candidate itself states the licence changed to Apache-2.0 from v12.0.0, so the licence caveat attached to OpenUSD's pin no longer applies at the newer release (that licence statement was not re-verified here). Limitations. Only the version pin was checked, not the OpenVDB LICENSE files. Version and 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) M2-03 from a discovery audit; the curator re-located the cited excerpts by timed GET. Limitations: Licence of 12.1.1 not re-read; relies on the candidate's own statement. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
