@dsh-lattice/transports

DSH Lattice V1 protocol transports: JSON-RPC Content-Length stdio server, CLI, an exactly-one-tool MCP server, config validation, and experimental fail-loud ACP client and A2A HTTP/JSON-RPC client.

Surfaces

Surface	Entry	Notes
JSON-RPC stdio	dsh-lattice serve	JSON-RPC 2.0 over Content-Length framing; methods lattice.ping, lattice.status, lattice.uto_run, lattice.shutdown
CLI	dsh-lattice run	deterministic result envelope → stdout, trace ref → stderr (ECC-V1.0 §14.2)
MCP server	dsh-lattice mcp	exactly one tool: lattice.uto_run (one-tool-per-caller)
Config validation	dsh-lattice validate	zod, .strict(): config is contract
ACP client	library	experimental, fail-loud, newline-framed JSON-RPC over stdio
A2A client	library	experimental, HTTP/JSON-RPC tasks/send|get|cancel, messages/send, Agent Card

All surfaces funnel into the single orchestration entry MemoryEngine.utoRun — the reference engine that implements the canonical envelope, deterministic idempotency keys (§9.3), duplicate suppression, capability preflight (fail loud), session modes with fingerprints and override authorization (§16), audit events and metric counters.
