## Summary
- normalize Vitest mock-call tuples before selecting graph
implementation sessions
- restore six clean-main executor assertions that otherwise misclassify
a routed implementation call as missing
## Test plan
- `pnpm --filter @fusion/engine exec vitest run --reporter=dot
src/__tests__/executor-review-verdicts.test.ts
src/__tests__/executor-worktree-liveness.test.ts`
- `pnpm --filter @fusion/engine typecheck`
- `pnpm test:gate:static`

* **Tests**
* Updated workflow routing and worktree liveness tests to use normalized
agent configuration when validating implementation-session selection.

routed implementation sessions.
