Archive old schema versions rather than deleting them,
Archive old schema versions rather than deleting them, preserving the complete trajectory of your thinking for comparison and potential rollback.
Why This Is a Principle
This principle derives from externalization exposing gaps (Externalization Exposes Hidden Structure), tacit knowledge degradation (Knowledge that exists only in tacit form degrades without), and reconstructive memory (Memory is reconstructive, not reproductive—humans rebuild). It prescribes preservation over deletion to maintain cognitive lineage.
