Tendon Message Protocol (TMP) - Next.js POC

This repository contains the initial TMP v3 protocol implementation surface and a Next.js proof-of-concept UI.

Included now

• ARCHITECTURE.MD: saved TMP v3 architecture specification.
• AGENTS.md: project agent operating guide.
• .agents/skills/*: foundational local skill packs for TMP work.
• src/lib/tmp/*: typed protocol models, envelope builders, and encoding helpers.
• src/app/api/protocol/envelope/route.ts: round-trip encode/decode API endpoint.
• src/app/page.tsx: protocol dashboard for sample unicast, multicast, and directive events.

Getting Started

Run the development server:

pnpm dev

Open http://localhost:3000.

Protocol endpoint

• GET /api/protocol/envelope returns sample TMP envelopes and a Nostr-wrapped event.
• POST /api/protocol/envelope accepts { "envelope": <TendonEnvelope> } and returns encoded/decoded round-trip data.

Current implementation note

Envelopes serialize to Protocol Buffers (proto/tendon.proto) and are Base64-encoded for Nostr content fields. Regenerate bindings after schema edits:

pnpm run proto:gen

Next protocol milestones

1. Add passkey + Argon2id vault unlock pathways.
2. Add OPFS/SQLite worker persistence and Negentropy reconciliation loop.
3. Implement gift-wrap unicast and epoch-based multicast key workflows.
