Partially verified: the curator re-read S19, S20, S27; S21, S22, S23, S24, S25, S26 were not re-read by the curator and rest on the producer's pinned reading. ambientCG states all assets are CC0 1.0 with no credit needed, but its API records carry no licence field (licence comes from the policy page), sampled dimension fields are 0 with no unit defined, and the operator warns the API may not be stable enough for enterprise use; v3 (from 2026-02-28) and repackaging updates change file names.

Curator qualifications: Partially verified: the curator re-read S19, S20, S27; S21, S22, S23, S24, S25, S26 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): S21: HTTP 200, bytes equal to the producer pin; S22: HTTP 200, bytes equal to the producer pin; S23: HTTP 200, bytes equal to the producer pin; S24: HTTP 200, bytes equal to the producer pin; S25: HTTP 200, bytes differ from the producer pin; S26: HTTP 200, bytes equal to the producer pin. API docs and two live records read 2026-10-22; no assets downloaded. v3 docs, Bricks001 v3 sample and updates page not re-read.

Limitations: API docs and two live records read 2026-10-22; no assets downloaded.

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