Platform Tiers

Lemon is a reduced headless platform. This document is the canonical runtime grading for the kept umbrella apps.

Use this doc alongside:

• architecture_boundaries.md for compile-time dependency policy
• quality_harness.md for CI and documentation gates
• root README.md for operator-facing entrypoints
• root AGENTS.md for engineering navigation

Runtime Profiles

• core: local coding substrate only
• platform: core plus gateway and control-plane runtime
