The posted SEP-1913 umbrella comment was updated to match the shipped structure: two extensions plus a schemes/ folder, with FIDES as one data-labelling scheme (ifc.fides.v1) rather than an extension/profile. Bring docs/intent-comment.md back in sync as the source of record and add the three stacked PR links (#2 base, #3 action-metadata, #4 FIDES scheme).

Carries forward the field semantics from SEP-2061 (Action Security Metadata) by @rreichel3, which @localden closed on 2026-06-13 in favour of this extension. SEP-2061 is preserved as the origin and credit. @connor4312's review of SEP-1913 — "InputMetadata/ReturnMetadata seem okay. I would be able to trust these as a client" — is the clearest external endorsement of this shape.
