The Alembic repository does not publish a curated sample-scene set. Its 46 .abc files are test inputs: mostly fuzzer and malformed-input regressions and security proof-of-concept files, plus two small renderer test files (prman cube.abc and xforms.abc). The only licence file is a BSD 3-clause text addressed to source and binary forms, which does not mention the .abc data, so reuse terms for those files are unclear.

Curator qualifications: Repository metadata read 2026-10-22; no .abc files downloaded or opened. .abc data rights unclear (BSD text names source/binary forms only); security PoC files should not be redistributed as samples. Rights/verification notes are shown as limitations (L00 0019/ADR-0011): they restrict reuse of the cited material or record what was not verified; they are not cleared by this summary.

Limitations: Repository metadata read 2026-10-22; no .abc files downloaded or opened. [component_reuse_restriction] Eligible as an observation; T15.05; keep .abc data on rights hold.

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