Balanov/latch — Minimal HTTPS contract for agent-to-service communication

Balanov/latch implements a minimal HTTPS contract protocol (LATCH) that enables secure, deterministic communication between any agent and any service. The project is built as a reference implementation in Node.js 20+, exposing a single POST endpoint (/latch) with five operations: GET for offer retrieval, ASK for read-only queries, QUOTE for offer validation without execution, COMMIT for approved execution, and STATUS for task monitoring. Evidence of readiness includes an open-source client/server/CLI triad in a single ESM file with zero runtime dependencies, a detailed specification in SPEC.md, and an optional MCP stdio bridge for cross-language interoperability. The current release is experimental (wire 0.1 / implementation 0.2.0) and runs without any registry, account, telemetry, hosted proxy, automatic installer, or payment rail. Production hardening considerations include the absence of persistent storage, distributed coordination, and exactly-once
