- walletmcp.py: stdlib stdio JSON-RPC MCP server; 7 outcome-first tools
with strict schemas; errors are structured (code/missing/remediation),
never prose; results carry evidence (structuredContent)
- custodycard.py: A2A-style card sharpened to self-proving - embeds each
member's LTL inclusion proof + STH so a counterparty recomputes trust
instead of believing it; proof-of-posture nonce challenge returns a
firewalled, signed posture attestation with the full quorum trail
- cli.py:
- verified end-to-end on the live wallet: all 7 MCP tools, structured
refusal on bad input, and a counterparty recomputing all 4 inclusion
proofs + STH signatures from the card alone (no operator trust)
