Kotlin/JVM client SDK

[neldroid]

Goal

A Kotlin/JVM client SDK for ORP, so Android and JVM apps can work with ORP documents and servers.

Scope proposal

• Data classes generated from, or checked against, the JSON Schemas in spec/2026-09-16/schemas/: profile, plan, adherence log and provider manifest.
• JSON Schema validation of documents.
• A typed wrapper around the MCP tool contract (spec/2026-09-16/mcp-tools.md) using the official MCP Kotlin SDK.
• Helpers to parse error codes (\b([A-Z][A-Z0-9_]+): ).
• A conformance check against the example documents in examples/.

Open questions

• Should it live in this repository or a separate open-routine-protocol-kotlin repository?
• Code generation versus hand-written models, plus a parity test, as in the Python implementation.
