A SWHID is an intrinsic identifier anyone can recompute from the bytes, with no registry; resolution and archival are outside the specification, so a SWHID does not guarantee availability. Software Heritage offers a web and /api/1/resolve/ resolver; Identifiers.org (core ids only) and N2T also resolve. swhid.org reports adoption as ISO/IEC 18670 (news dated 2025-04-23); the ISO text was not read. Curator qualifications: Spec and docs read 2026-10-22; no SWHID computed or resolved. ISO text paywalled. Limitations: Spec and docs read 2026-10-22; no SWHID computed or resolved. Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
