# User wash start production-readiness QA matrix
This note documents deterministic coverage for the self-serve user wash start flow. The `@dynamic-image` Playwright case remains separated because it validates rendered image behavior in addition to deterministic state and API transitions.
## Unit matrix
| Area | Required scenario | Coverage |
| ----------------------- | ------------------------------------------------------------------------------------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| `useWashFlowState` | Step transitions for vehicle, questions, lane, tasks, in-progress, completed | `tests/unit/use-wash-flow-state-production.spec.js` validates step clickability, next-button gating, questions-to-lane updates, lane-to-start target selection, task completion transition, in-progress navigation, and completed-step non-clickability contract. |
| `useWashSessionActions` | START success and failure | `tests/unit/use-wash-session-actions-production.spec.js` covers successful manual START state mutation and failed START retryability without active-wash mutation. |
| `useWashSessionActions` | Relay enable success and relay enable failure with STOP rollback | `tests/unit/use-wash-session-actions-production.spec.js` covers machine relay success and relay failure rollback via STOP. |
| `useWashSessionActions` | STOP failure and already-stopped STOP recovery | `tests/unit/use-wash-session-actions-production.spec.js` covers failed STOP preserving active state and already-not-occupied STOP clearing local state. |
| `useSelfServeLogic` | Preview/summary merge | `tests/unit/use-self-serve-logic-production.spec.js` covers preview questions merging with summary questions, answer maps, visible question order, tasks, and allowed services. |
| `useSelfServeLogic` | Request race handling | `tests/unit/use-self-serve-logic-production.spec.js` covers stale preview/summary responses being ignored when a newer request wins. |
| `useSelfServeLogic` | Allowed services updates | `tests/unit/use-self-serve-logic-production.spec.js` covers lane allowed-service endpoint updates and first-failure fallback behavior. |
| `useSelfServeLogic` | Answer sync failures | `tests/unit/use-self-serve-logic-production.spec.js` covers error reporting while preserving the caller's optimistic local answer. |
| `MyWashStart.vue` | Local progress restore, server active-wash restore, recent-completion suppression, unmount cleanup, duplicate-fetch prevention | `tests/unit/my-wash-start-production.spec.js` locks the component contracts for restore ordering, authenticated active-wash application, recent-completion suppression across restore/polling, unmount cleanup, and duplicate-fetch/sync guards. |
## E2E mocked matrix
| Required scenario | Coverage |
| -------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Full manual flow | `tests/e2e/self-serve-wash.spec.js` covers direct manual wash start, guided completion, STOP, exit-gate open, completed state, and close/reset. |
| Full machine flow | `tests/e2e/self-serve-wash.spec.js` covers machine task rendering, dynamic image progress, required task completion, machine start path, and reload persistence. |
| Reload/resume active wash | `tests/e2e/self-serve-wash.spec.js` covers local progress reload and authenticated server active-wash resume from another device. |
| Backend says wash completed during polling | `tests/e2e/self-serve-wash.spec.js` covers server polling of active wash and local transition to completed when the backend no longer reports the matching in-progress wash. |
| Network failures for preview, answer sync, START, relay enable, STOP | `tests/e2e/self-serve-wash.spec.js` covers retryable START failure, STOP failure preservation, allowed-services gateway timeout/retry, answer sync background resilience, and unit-level relay rollback. Add mocked network route overrides when expanding browser-level failure assertions. |
## Optional live smoke
| Optional scenario | Coverage |
| ------------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Dynamic image smoke | The `@dynamic-image` Playwright test in `tests/e2e/self-serve-wash.spec.js` is tagged separately from deterministic CI coverage so it can be included or excluded explicitly with Playwright grep controls. |
