+- Define: goal, constraints, assumptions, stakeholders, success criteria, deadline.
+- Evidence: inputs, data sources, error budgets, known edge cases.
+- Plan: options with trade-offs, chosen path, rollback.
+- Execute: deterministic seed, idempotent steps, timeouts, retries (bounded).
+- Validate: assertions, golden tests, invariants, acceptance criteria met.
+- Document: decisions, risks, follow-ups; attach logs/artifacts.
