Summary

AID-EMIT-1 1.2.0-draft. Section 1.1 pinned the cpex.* / cmf.* field names to the CPEX host family and pointed any host with a different message format at AID-EMIT-2. The signing, chain and stream rules do not depend on the host; only the names do. This resolves that case additively instead of forking the spec.

• New section 1.2, Vocabularies. A vocabulary names the unmapped members that carry the format's own facts. cpex keeps the section 1.1 names. aid (aid.stream, aid.decision, aid.span, aid.content, aid.request_id, aid.<host>.*) is for emitters that target the AI Identity platform and OCSF rather than a gateway, starting with the LiteLLM adapter designed in docs(specs): Python AID-EMIT-1 emitter and LiteLLM adapter design drafts #600.
• Six rules: same structure and semantics across vocabularies; one vocabulary per record (MUST); verifiers read aid first and SHOULD surface a record with stream stamps under both; under aid, a fact with a native OCSF field MUST use it and MUST NOT be repeated under unmapped; no covered-bytes change and the same wire-name stability as section 1.1; no in-record vocabulary marker; a non-CPEX emitter conforms as an Emitter and documents how it attaches, including whether it sees denied requests.
• Sections 7, 8, 9 name the aid counterparts in place. Section 12 notes that no aid vector exists yet. Section 13 records 1.2.0 as MINOR.
• Version 1.2.0-draft, date 2026-10-12. CHANGELOG entry under Added.

Needs a human pass

Standards-facing wording. The normative choices to check:

• Rule 2 makes one vocabulary per record a MUST for emitters, but only a SHOULD-surface finding for verifiers (the validator from feat(validator): read stream stamps from aid.stream as well as cpex.stream #601 warns W-STREAM-VOCAB; platform ingest records an anomaly). That keeps mixed records verifiable rather than rejected.
• Rule 3 applies native-OCSF-first as a MUST to aid only, so no existing cpex record becomes non-conformant.
• Rule 6 is new: section 10's host registration contract describes the CPEX seam, so a non-CPEX emitter is held to the Emitter class rather than the Host seam class.

Testing

Spec text only. The edits apply to the current main copy of docs/specs/aid-emit-1.md at ten exact-match anchors, all or nothing. The validator merged in #601 already reads both vocabularies in the order rule 2 states.
