  "purpose": "Machine-readable index of CAIN 42.0 evidence -- the session in which MCP, A2A, supply-chain provenance, and an identity-registry reconciliation fix (all previously NOT ATTEMPTED per CAIN 37-41's own limitations files) were built for real. Additive to every prior /.well-known manifest.",
  "what_is_implemented_and_verified_this_session": {
    "mcp_integration": "REAL, LIVE -- built on the official `mcp` Python SDK v2.2.0. cain_mcp_trust_42.py enforces DISCOVER->TRUST->AUTHORIZE->EXECUTE against a real running server (cain_mcp_demo_server_42.py). 8/8 tests pass, including untrusted-server and identity-mismatch rejections.",
    "a2a_integration": "REAL, LIVE -- this session's own implementation of the public A2A message shapes (no official Python SDK exists), same 4-gate trust model. 6/6 tests pass.",
    "supply_chain_provenance": "REAL -- a signed manifest chaining git commit + dependency-lock hash + constitution hash (all independently recomputable from a repo checkout) + an honestly-labeled ATTESTED (not independently verified) container digest. 4/4 tests pass.",
    "identity_registry_reconciliation": "REAL, PARTIAL -- identity_engine.revoke_identity() now cascades to revoke the corresponding agent_identity_attestation record (one-directional: identity revocation implies attestation revocation, not the reverse, which remains a deliberate, documented design choice). Closes the gap CAIN 38-41 repeatedly flagged as unresolved.",
    "agent_collusion_demonstration": "REAL (small-scale, 20 scripted agents) -- proves, not just claims, that a colluding bloc can force an APPROVED decision on a bad proposal under plain majority rule, and that raising the quorum_fraction (an existing, already-built lever) is a genuine working mitigation. 4/4 tests pass."

See CAIN42_MIGRATION_PLAN.md for the honest assessment of what remains before a full architectural convergence/rename would be justified -- this session closes several real gaps but does not claim the mission's full 59+-phase scope is now complete."
