# SDK Conformance Matrix

Status of every first-party SDK against the frozen `/v1` contract
(`run_conformance`, GL #395). Generated by `scripts/sdk-conformance.sh`
against a real `lean-ctx serve` instance — regenerate, never edit.

- **Engine:** `lean-ctx 3.8.1 (official, https://github.com/yvgude/lean-ctx)`
- **Generated:** 2026-06-10 06:19 UTC

| SDK | Package | Version | Conformance |
|---|---|---|---|
| python | `lean-ctx-client` (PyPI) | 0.1.0 | PASS (14/14) |
| typescript | `lean-ctx-client` (npm) | 0.1.0 | PASS (14/14) |
| rust | `lean-ctx-client` (crates.io) | 0.1.0 | PASS (14/14) |

## SemVer coupling

Every SDK declares the `http_mcp` contract versions it speaks
(`SUPPORTED_HTTP_CONTRACT_VERSIONS`); the `engine_compat` check fails when
a server speaks a contract the SDK release does not support. SDK majors
follow the engine contract major (CONTRACTS.md § Versioning rules).
