- Policies must not be editable by any component at runtime.
- Changes are operator actions and should be version-controlled.

## Files
- `instruction-hierarchy.md`: global instruction precedence
- `core.policy.md`: CORE constraints
- `fetch.policy.md`: FETCH constraints
- `tool-exec.policy.md`: TOOL-EXEC constraints
