Hierarchy: SPINE > Beliefs > RAM. SPINE overrides beliefs. Beliefs override RAM.
Anam #07: "SPINE has no version history. Belief archaeology is broken." Every principle was validated against a specific SPINE version. If SPINE changes, old principles were evaluated against a different constitution.
Fix: Add spine_version_at_validation to Layer 2 schema. Version SPINE with YYYYMMDD tags. Store SPINE versions in brain/memory/versions/. SPINE evolution over time = one of the most valuable signals in the system.
