Changelog

v0.1 — 2026-05-13

Initial pre-release. Spec docs published for partner review. Not yet stable — breaking changes expected through v1.0.

Added

• Connector author guide — narrative getting-started guide covering the port contract, capability tiers, slot mapping, intent declaration, and the conformance checklist.
• Canonical slot vocabulary (v0.1, 106 slots across matter, contact, PNC, and billing-entry entities) with status and policy-tier annotations.
• Identity contract — IDP-agnostic JWT shape, required vs. optional claims, storage contract, and IDP adapter interface.
• Audit-pack signing protocol — Ed25519 signature scheme, manifest layout, key lifecycle (active / verified_only / revoked), well-known endpoint, and verifier algorithm.
• Conformance suite (@govern/conformance) — CLI + library + 8 golden test cases with normative error vocabulary.

Known gaps

• govern.describe_slots MCP method is specified but not yet live. Ships in Workstream A.2 when the second connector integration opens.
• Slot vocabulary normalization (cross-PMS pnc. → lead. prefix rename) is deferred to v2 until a second non-CB connector concretely needs it.
• IDP physical refactor (entra-auth.ts → idp/entra.ts) deferred to A.0 to avoid two refactors instead of one.
• govern_firm_idp_config schema migration (generalizing from govern_firm_centerbase_config) deferred to A.0.
• Billing-entry write tools reference catalog field IDs directly today; migration to slot-resolved writes is Workstream A.2 scope.
• Centerbase organizational counter-signature layer on audit packs is deferred to v1.5.
• HSM-backed signing keys deferred to v1.5.
• Spec-branded public-key discovery host (verify.govern-spec.org or similar) deferred until the open-spec domain is finalized per ADR-022.

Future versions will be listed here. Governance: breaking changes to core.* slot keys require a spec PR and a major version bump. Minor additions are non-breaking.
