Optimize for the intended, verifiable end state rather than preserving smooth intermediate states.
Why: Keeping every intermediate step fully stable often creates temporary compatibility code that becomes long-lived debt. Converge on the target architecture and prove correctness at explicit verification boundaries.
Core rule:
- Prioritize end-state integrity over transitional stability
- Intermediate breakage is acceptable when it is planned, scoped, and reversible
Guardrails:
- Use this for planned rewrites and migrations with explicit phase boundaries
- Declare where temporary breakage is acceptable
- Keep high-signal checks for actively touched areas while migrating
- Require full static and runtime verification at plan completion
