At ayon-backend 0a2e5cdd, uniqueness is scoped case-insensitively by parent: folder names under a parent, product names per folder, version numbers per product and representation names per version, with the product/version/representation rules applying only to active rows; the licence is FSL-1.1-ALv2 (source-available, no Competing Use, converting to Apache-2.0 two years after each release), which GitHub metadata reports as NOASSERTION.

At ayon-backend 0a2e5cdd, uniqueness is scoped case-insensitively by parent: folder names under a parent, product names per folder, version numbers per product and representation names per version, with the product/version/representation rules applying only to active rows; the licence is FSL-1.1-ALv2 (source-available, no Competing Use, converting to Apache-2.0 two years after each release), which GitHub metadata reports as NOASSERTION.

Curator qualifications: Links table structure (E5) and Zou EntityLink comparison (E6) not re-read verbatim. ayon-core / ayon-python-api Apache-2.0 metadata (producer note) not read. FSL is not an OSI open-source licence; Competing Use limits apply until the Apache conversion date of each release. Static reading only; no database created. 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: Static reading only; no database created. [component_reuse_restriction] Do not describe ayon-backend as open source or Apache-licensed for current releases.

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