The replacement test: - Type-level exhaustive switch covers all 4 union variants explicitly - If a NEW variant is added without updating the switch, TS strict mode raises "not all code paths return a value" at compile time (caught by lint(tsc tools) CI gate) - Iterates real SEED_STATES values rather than literal array (catches real behavior, not literal-array-self-checking) Gate verification: - bunx tsc --noEmit (tools/workflow-engine) → 0 errors - bun test tools/workflow-engine/ → 12 pass / 0 fail / 21 expect() Pushing to the existing #5728 branch so CI re-runs + Copilot thread can be resolved + auto-merge fires.
