Changelog

Every change an integration could notice — to an API, an error code, a signed format, a verifier library or the security model — is listed here, newest first. Within /v1/ changes are additive only (Deprecation policy).

Version 1

The retrieval, verification and business APIs, as documented in the API reference, with these signed formats:

Artefact	Format in force	Also verified
Business seal	seal.v2 (names ai_policy_version)	seal.v1 (names terms_version)
Batch seal	batch-seal.v2	batch-seal.v1
Receipt	receipt.v3 (each row names ai_policy_version)	receipt.v2, receipt.v1
Sidecar	sidecar.v2	sidecar.v1
Projection specification	v3	v1, v2 (their rows verify with ai_policy_bits removed first)
ADL Certificate	v 1	—
Key custody statement	key-custody.v1	—
Verify page	verify-page.v1	—
Source line	mdb-source/1	—
AI policy record	masterdb/ai_policy/1, ai_policy_schema 2	ai_policy_schema 1, and the earlier masterdb/terms/1 form

The verifier libraries accept every format in the table and refuse any version they do not know.
