  "_note": "WritersLogic entries in the C2PA Soft Binding Algorithm List (github.com/c2pa-org/softbinding-algorithm-list). Six are registered and carry assigned identifiers; the semantic fingerprint is still held pending publication of cross-platform int8 test vectors proving reproducibility, so it has no identifier. All WritersLogic informationalUrls follow https://docs.writerslogic.com/soft-binding/<slug>. Authoritative descriptions live in the upstream list; this file mirrors registration state. Verified against the upstream list on 2026-08-25 (53 entries total).",
