Architectural Invariants¶
The canonical, complete statement of the eight invariants (INV-001 … INV-008) lives in the reference section, kept in one place so the rules never drift between copies:
The other architecture documents — Design Principles, Extending HilbertBench, and Versioning — refer to those invariants by number. Each one is a non-negotiable guarantee; a change that breaks it is rejected in review.
