This matrix captures branch truth for skill tiering and surface ownership.
- Public surface: user-facing entrypoints and operator-facing outputs.
- Internal surface: orchestration, planning, and lifecycle internals.
- Programmatic surface: manifests, specs, behavior contracts, and script entrypoints.
- Core: required for baseline skill-system operation and governance.
- Support: important domain capabilities and operator tools built on top of core.
- Lab-off-scope: intentionally experimental or not part of the current production contract.
