Version compatibility

​

Current public package line

​

Wire compatibility

• Praxa-named SDK and MCP exports preserve established Aura-compatible wire values.
• Do not rewrite x-aura-contract-version, aura_* MCP tool names, or MCP_SERVER_NAME = “aura-agent-os” as display-branding cleanup.
• MCP_SERVER_VERSION is the package/server version. It is not the MCP protocol revision.
• The SDK’s OpenAPI fingerprint can be asserted at startup when your deployment pins an exact contract.

​

Upgrade check

1. Install the new package in a clean project.
2. Compare exported version and fingerprint constants.
3. Review route, scope, idempotency, and response metadata.
4. Compile your application and run contract tests.
5. Run authenticated positive and negative canaries against the intended Gateway.
