Archon v0.10.0

Release Highlights

This release introduces end-to-end encrypted DIDComm Messaging v2, ships an Archon MCP server for AI-agent integration, adds node capability negotiation, and hardens mediator stability and deployment security.

✉️ DIDComm Messaging v2

A complete, interoperable DIDComm v2 implementation lands across the stack:

• Phases 0–7: TypeScript + Python parity, encrypted transport, messaging protocols, and endpoint auto-discovery (#633)
• Phase 8: all sends routed through the DIDComm service for Tor egress (#643)
• Mailbox reads now go through the local gateway rather than the public endpoint (#646)
• Field fixes: pass ARCHON_DRAWBRIDGE_PUBLIC_HOST to the Drawbridge service for correct endpoint discovery (#640)
• Isolated the in-process DIDComm e2e from the unit run; added a DIDComm CLI e2e against Docker (#650, #644)

🤖 Archon MCP Server

• New Model Context Protocol (MCP) server exposing Archon to AI agents (#605)
• Expanded MCP tooling toward full Keymaster CLI parity (#606)

🧩 Node Capabilities

• Node capability manifest + client gating for optional services, so clients negotiate against what a node actually offers (#648)

🛠️ Mediator Stability

• Fixed Satoshi mediator OOM during pruned-block catch-up (#595)
• Stopped Satoshi historical-scan logging from exhausting memory (#604)

🔒 Security & Deployment

• Bound the bundled Tor SOCKS port to localhost (#590)
• Hardened the LNbits CLN REST startup wait (#591)

🚀 CI & Publishing

• Added a Python Keymaster PyPI publish workflow (#651)

📚 Documentation & Maintenance

• New Clean Architecture assessment doc (#587)
