Released client evidence¶

• hayate-openapi 0.8.2 generates the dependency-free callable TypeScript client and validates it against a real Hayate ASGI process.
• create-hayate 0.14.0 propagates the client, its types, and drift checks into generated projects. Its production Workers template also propagates application and Cloudflare deployment identity to every response.
• hayate-mcp 0.12.1 passes the official 70-case MCP 2026-07-28 conformance suite, real Workerd execution, and release provenance checks.
• hayate 0.15.3, hayate-sql 0.1.2, hayate-fetch 0.1.4, and hayate-auth 0.10.5 publish immutable wheels with SLSA provenance and SPDX SBOMs.
• Its release workflow resolved and imported all 52 supported backend compositions before publishing the signed, attested wheel.
• The 0.14.0 public wheel also passed the full 112-case composition matrix across backend and frontend combinations, ASGI, and real Workerd. No expected case was missing or failed. The aggregate evidence JSON SHA-256 is d980477da29e494182080adcd79b864ab533a1dcfbc8035b401f75f7dfa97e43.
• The golden application main run executes authenticated path, query, JSON, multipart, delete, and error flows through the compiled client and locks hayate 0.15.3, hayate-mcp 0.12.1, hayate-openapi 0.8.2, and hayate-sql 0.1.2.
• The same run proves both class and global Workers entrypoints under real Workerd. Each returns X-Hayate-App-Version: 0.1.0 and a platform-issued X-Hayate-Worker-Version UUID. The ASGI smoke returns the app version and deliberately omits the Worker-only identifier.
