Feature-free stabilization and pre-1.0 contract freeze.
- Freezes the six-tool MCP, versioned HTTP/SSE, primary CLI, logical evidence, cache lifecycle, calculation-grade, four-token-class, JSON export, privacy, installation, and upgrade contracts.
- Qualifies fault recovery, scale, concurrent reads, rollback, and direct upgrades from public 0.26.0 and 0.27.0.
- Keeps optional context composition experimental and the overlay as a read-only contract without a shipped runtime.
