Feature parity contract prepared.

Added

• External integrator guide, API guide, example UI, roadmap and changelog pages.
• Feature parity map for registry, risk, approvals, evidence, regulatory posture, vendors, incidents, reviews, team, notifications and exports.
• Capability APIs for risk evaluation, claim boundaries, evidence sanitisation, access logs, regulatory profiles, integrity verification and proof packets.
• Local HTTP API preview for event write, timeline, search, Claim Boundary and Proof Packet route implementation.
• Example token examples and local smoke fixtures.
• Contract conformance gate for source links, required Blackboard ensemble terms, event-type coverage and forbidden customer-doc wording.

Not production proof yet

• No deployed production Risk Evaluation Service is claimed.
• No deployed multi-tenant SaaS isolation proof is claimed.
• No customer-ready MCP gateway or `blackboard` CLI is claimed.
• No automatic semantic correctness claim is made.

Allowed wording

Blackboard records signed or hash-bound events according to policy, assembles deterministic proof packets, and can bind receipts where policy requires. Receipts prove bytes and binding metadata, not semantic correctness.
