Currently, our Playwright + Claude implementation covers the happy path E2E flow. With this implementation, we can extend the automation coverage to validate the Replay functionality after a player fails a level, ensuring the same level is restarted correctly and is fully playable. + +### Business Goal +Extend the existing Playwright + Claude E2E suite so that the **Replay Level** action — a core recovery path players use after an unsuccessful or repeat attempt at a level — is regression-tested automatically, closing a gap in coverage that today only exercises the "happy path" (complete a level → advance/return to map). + +### Problem Statement +`FTM_TC_016` (`e2e/tests/isolated/tc-016-level-completion.spec.ts`) proves the Level End screen renders correctly (stars, buttons, Rive monster) and that the **Map** button returns the player to Level Selection. It does **not** exercise the **Replay** (`#levelend-retry-btn`) button at all. There is currently zero automated coverage verifying that clicking Replay reloads the same level, resets puzzle progress, and leaves the gameplay canvas fully interactive — a functional path (`levelend-scene.ts` → `buttonCallbackFn('retry')`) that a regression could silently break. + +### Acceptance Criteria (from FM-967) +1. Automate the Replay Level flow using the existing Playwright + Claude automation framework. +2. Validate that selecting Replay from the Level End screen restarts the same level successfully. +3. Verify that the gameplay loads correctly after replay is initiated. +4. Ensure the replayed level is fully interactive and can be played from the beginning. +5. Verify that the correct level context is maintained after replay. +6. Integrate the automation into the existing FTM E2E test suite. +7. Ensure the test follows the existing framework standards, reusable helpers, and coding conventions. +8. Ensure the automation executes reliably in CI with consistent, non-flaky results. + +**User-specified execution sequence (this task's explicit steps):** +1. Confirm the Level End screen from `FTM_TC_016` loads properly. +2. Wait 2 seconds (post-load settle time before interacting with Replay). +3. Click the Replay button — expected to reload **Level 2** (the level the orchestrator suite currently plays, 0-based `currentLevel === 1`). + +--- + +# 1. Executive Summary + +This spec defines **`FTM_TC_017 | Level Replay`**, a new Playwright E2E test that runs immediately after `FTM_TC_016` in the existing serial suite. It asserts that clicking the Level End screen's Replay button reloads the *same* level (Level 2) with a fresh, interactive puzzle state — closing the AC gap in FM-967. + +- **Business objective:** regression-proof the Replay recovery path so a broken `levelend-scene.ts` retry handler is caught in CI before reaching players. +- **Expected user impact:** none directly (test-only change); indirectly reduces risk of a shipped regression that traps players on a level they can't restart. +- **Success metrics:** new test passes reliably in CI (`e2e-tests` CircleCI job) across ≥20 consecutive runs with zero flake; zero new page-object or helper code needed beyond one small addition (see §7). + +--- + +# 2. Current State Analysis + +**Existing implementation:** +- `e2e/tests/ftm-assessment-survey-flow.spec.ts` — orchestrator; registers `tc001 → tc002_003 → tc004_005 → tc006_008 → registerTC009_012 → tc014_015 → registerTC013 → tc016` inside one `test.describe.serial` block sharing a single `page` and two shared-state objects (`SharedFlowState`, `FullGameplayFlowState`). Neither shared-state object tracks a level number field. +- `e2e/tests/isolated/tc-016-level-completion.spec.ts` — the last registered test. It: + 1. Waits (35s) for `#levelEnd` to become visible naturally (no synthetic events published). + 2. Asserts ≥1 star rendered. + 3. Asserts `#rivecanvas` attached. + 4. Asserts Map and Next buttons visible. + 5. **Clicks Map** → asserts return to `#level-selection-container`. +- `e2e/pages/level-end-page.ts` (`LevelEndPage`) **already exposes everything needed to click Replay** — no new page-object code required: + - `SELECTORS.retryButton = '#levelend-retry-btn'` + - `retryButton` getter + - `assertRetryButtonVisible()` + - `clickRetryButton()` (waits for visibility with `Timeouts.evolutionDelay`, then clicks) +- `e2e/pages/gameplay-page.ts` (`GameplayPage`) exposes `waitForGameplayScene()` (asserts `#canvas` + `#pause-button` visible within `Timeouts.sceneTransition`), used elsewhere as the standard "gameplay scene is active" check. +- `e2e/helpers/canvas-helpers.ts` exposes `assertCanvasHasContent(page, selector)` — used elsewhere to confirm stones have rendered. +- `e2e/helpers/game-state-helpers.ts` exposes `triggerLevelEndScene(page, starCount, currentLevel, isLastLevel)`, a synthetic shortcut already used by other isolated specs to reach the Level End screen without playing a full level. + +**Current limitations:** +- No test ever exercises `#levelend-retry-btn`. +- No assertion anywhere in the suite reads `selectedLevelNumber` / `currentLevelData` from `window.__ftm.gameStateService` to prove *which* level is active — level identity is not surfaced in the DOM, so "same level restarted" can only be verified programmatically. +- `e2e/constants/timeouts.ts` has no constant for a deliberate short settle delay (closest are `buttonAnimation: 500` and `stoneDrop: 1_000`); a literal 2s wait as requested has no existing named constant. +- `e2e/tests/README.md`'s TC table stops at `TC_0016`; no `TC_017` is reserved yet. + +**Technical debt:** none introduced by this change if the recommended approach (§4) is followed — it is purely additive. + +--- + +# 3. Root Cause Analysis + +This is a **test-coverage gap**, not a runtime defect. Root cause: the original E2E suite (per its header comment in `ftm-assessment-survey-flow.spec.ts`) was scoped to the happy-path flow (`App launch → ... → Natural level completion (TC_016)`) and Replay was out of scope at the time. `levelend-scene.ts` has supported Replay since before this suite existed (`buttonCallbackFn('retry')`, `handleRetryOrNext`), so there is no architectural or performance bottleneck to address — only a missing test. No CPU/memory/offline impact analysis applies; this section is intentionally short because the work is additive test coverage, not a fix to a bottleneck. + +--- + +# 4. Proposed Solution + +## High-level approach +Add **`FTM_TC_017 | Level Replay`** as a new isolated spec file (`e2e/tests/isolated/tc-017-level-replay.spec.ts`) following the exact `registerTests(getPage)` pattern used by every other isolated file, registered in the orchestrator immediately after `tc016(page)`. The test performs, as **four composable "aspects"** (see §5 for why this structuring is used): + +1. **Arrange/Reach aspect** — confirm the Level End screen described by `FTM_TC_016` is present and loaded (reuse `LevelEndPage.assertLevelEndVisible()` / the same visibility checks TC_016 already performs). +2. **Settle aspect** — an explicit, intentional `page.waitForTimeout(2_000)` (new named constant, see §7) after the screen is confirmed loaded, per the ticket's explicit sequencing requirement. +3. **Interact aspect** — click Replay via `LevelEndPage.clickRetryButton()` (already exists, no new code). +4. **Verify aspect** — confirm (a) the gameplay scene reloads (`GameplayPage.waitForGameplayScene()`), (b) the canvas has re-rendered interactive content (`assertCanvasHasContent`), and (c) the level context is unchanged — read `selectedLevelNumber` from `window.__ftm.gameStateService` via `page.evaluate` and assert it still equals `1` (0-based Level 2, the level the orchestrator plays). + +## Why this approach was selected +- Satisfies every AC in FM-967 using **only existing helpers and page objects** (AC 1, 6, 7) — the only new code is one timeout constant and one new spec file. +- Keeps `tc-016-level-completion.spec.ts` **untouched**, eliminating regression risk to already-passing coverage (aligned with the "avoid unnecessary refactoring" SDD principle). +- Matches the project's established dual structure: one test per TC number, registered both in the isolated file and the serial orchestrator. + +## Alternative approaches considered + +| Approach | Description | Trade-off | +|---|---|---| +| **A — Extend natural flow in-place (rejected)** | Remove/relocate the "click Map" step from `tc-016-level-completion.spec.ts` so the *same* Level End screen instance TC_016 reaches is reused by TC_017 before Replay is clicked, then have TC_017 (not TC_016) perform the return-to-map assertion. | Higher fidelity (single continuous natural flow) but **modifies an existing, passing, documented test** (`FTM_TC_016`'s Jira/QA-doc description says it ends by returning to the map) — this is a behavior change to a shipped, previously-signed-off test case, not purely additive. Higher review/regression risk for no measurable extra coverage value, since Level-End-screen-is-loaded is already proven by TC_016 regardless of which test clicks which button next. | +| **B — Synthetic reach via `triggerLevelEndScene` (rejected as primary, viable as fallback)** | Skip natural gameplay entirely; call `triggerLevelEndScene(page, 3, 1, false)` to jump straight to Level End, independent of TC_001–016. | Fastest, fully isolated, zero dependency on the long natural flow (35s wait) — best for the standalone `test:e2e:isolated` run. But bypasses `handleLevelCompletion`'s real event chain, so it verifies Replay in isolation from "just completed a level naturally," which is weaker evidence for AC 2 ("restarts the same level **successfully**" in the context the ticket describes: "after a player fails a level"). | +| **C — Selected: sequential registration after TC_016, own explicit checks (chosen)** | New `FTM_TC_017` test, registered after `tc016(page)` in the orchestrator, re-asserts Level End is visible (cheap, since it's still on-screen — TC_016's last action was clicking Map, so **this requires the ordering nuance in §14 Open Question 1** — see below), then does Settle → Interact → Verify. | Best balance: purely additive, reuses natural flow evidence, minimal new code, no changes to TC_016. Carries one open sequencing question flagged for confirmation before implementation (§14). | + +## Business value +Directly satisfies FM-967 without expanding scope, keeps CI runtime impact small (one extra test, no duplicated 35s natural-completion wait if ordering is resolved per §14), and produces a regression net around a real player-facing recovery path. + +--- + +# 5. Architecture Hooks + +**Why "aspect-driven":** Playwright has no native AOP/decorator mechanism, so "aspect-driven" here means structuring the single `FTM_TC_017` test as **independent, composable `test.step()` blocks**, each owning exactly one cross-cutting concern, mirroring the existing convention already used inside `tc-016-level-completion.spec.ts` (each `test.step` there is already single-purpose: visibility, stars, buttons, navigation). This keeps failures attributable to one concern and lets future tests reuse individual steps as helpers if needed. + +| Aspect | Concern | Implementation hook | +|---|---|---| +| Arrange/Reach | Level End screen is loaded (TC_016 precondition) | `LevelEndPage.waitForLevelEndScene()` / `assertLevelEndVisible()` | +| Settle | Deliberate pre-interaction delay (ticket-mandated 2s) | `page.waitForTimeout(Timeouts.replaySettleDelay)` — new constant, §7 | +| Interact | Click Replay | `LevelEndPage.clickRetryButton()` (existing) | +| Verify — scene | Gameplay scene reloaded | `GameplayPage.waitForGameplayScene()` (existing) | +| Verify — render | Canvas is interactive/re-rendered | `assertCanvasHasContent(page, GameplayPage.SELECTORS.mainCanvas)` (existing) | +| Verify — context | Same level (Level 2 / `selectedLevelNumber === 1`) restarted | `page.evaluate(() => window.__ftm.gameStateService.gamePlayData.selectedLevelNumber)` (existing global; new assertion only) | + +**Existing modules involved:** `e2e/tests/ftm-assessment-survey-flow.spec.ts`, `e2e/tests/isolated/tc-016-level-completion.spec.ts` (read-only reference, no edits), `e2e/pages/level-end-page.ts`, `e2e/pages/gameplay-page.ts`, `e2e/helpers/canvas-helpers.ts`, `e2e/constants/timeouts.ts`, `e2e/constants/selectors.ts`. + +**Production code hooks (no changes needed, documented for QA traceability):** `src/scenes/levelend-scene/levelend-scene.ts` (`buttonCallbackFn('retry')` → `handleRetryOrNext(this.currentLevel)`), `src/sceneHandler/scene-handler.ts` (`SWITCH_SCENE_EVENT('GamePlay')` dispatch), `gameStateService.EVENTS.GAMEPLAY_DATA_EVENT` / `SWITCH_SCENE_EVENT`. + +**State management:** No new client-side state. Test-side, the new isolated file introduces no new shared-state interface (unlike `SharedFlowState`/`FullGameplayFlowState`) since it needs no cross-test data beyond the shared `page`. + +**Rendering / asset paths exercised:** Level End teardown (`LevelEndScene.dispose()`, 500ms after retry) racing against `GameplayScene` construction — this is exactly why the Verify aspect must wait on `GameplayPage.waitForGameplayScene()` rather than assume synchronous readiness. + +--- + +# 6.

File-Level Implementation Plan + +### `e2e/tests/isolated/tc-017-level-replay.spec.ts` (new) +- **Purpose:** implement `FTM_TC_017 | Level Replay`. +- **Required changes:** new file, `export function registerTests(getPage: () => Page): void`, mirroring the shape of `tc-016-level-completion.spec.ts`. +- **Public API:** exports `registerTests` (consumed by the orchestrator). +- **Internal steps (test.step blocks, one per aspect from §5):** + 1. `'Level end screen from TC_016 is still loaded'` — `expect(page.locator(LevelEndPage.SELECTOR)).toBeVisible()` (cheap re-check; screen should already be visible per TC_016). + 2. `'Wait for UI to settle before interacting with Replay'` — `await page.waitForTimeout(Timeouts.replaySettleDelay)`. + 3. `'Click Replay button'` — `await levelEndPage.clickRetryButton()` (via `LevelEndPage` page-object fixture) or `await page.locator(LevelEndPage.SELECTORS.retryButton).click()` if not using the fixture-bound instance — follow whichever pattern `tc-016` uses (raw `page.locator`) for consistency. + 4. `'Gameplay scene reloads after Replay'` — `await gameplayPage.waitForGameplayScene()`. + 5. `'Gameplay canvas re-renders with interactive content'` — `await assertCanvasHasContent(page, GameplayPage.SELECTORS.mainCanvas)`. + 6. `'Same level (Level 2) context is maintained after replay'` — read and assert `selectedLevelNumber`: + ```ts + const restartedLevel = await page.evaluate( + () => (window as any).__ftm.gameStateService.gamePlayData.selectedLevelNumber, + ); + expect(restartedLevel).toBe(1); // 0-based → "Level 2" + ``` + +### `e2e/tests/ftm-assessment-survey-flow.spec.ts` (modified) +- **Purpose:** register the new test in the serial suite. +- **Required changes:** add `import { registerTests as tc017 } from './isolated/tc-017-level-replay.spec';` alongside the existing imports; add `tc017(() => page);` immediately after the existing `tc016(() => page);` line. +- **Public API affected:** none (internal test registration only). + +### `e2e/constants/timeouts.ts` (modified) +- **Purpose:** name the ticket-mandated 2-second settle delay instead of a magic number. +- **Required changes:** add one key, following existing naming/comment conventions: + ```ts + export const Timeouts = { + // ...existing keys unchanged... + replaySettleDelay: 2_000, // deliberate pause after Level End loads, before clicking Replay + } as const; + ``` + +### `e2e/tests/README.md` (modified) +- **Purpose:** keep the TC-numbering table authoritative. +- **Required changes:** add a row: `tc-017-level-replay.spec.ts | TC_0017 | Replay button restarts the same level with fresh, interactive puzzle state`. + +**No changes required to:** `e2e/pages/level-end-page.ts`, `e2e/pages/gameplay-page.ts`, `e2e/helpers/*`, `e2e/constants/selectors.ts`, `e2e/fixtures/game-fixtures.ts`, any `src/**` file. + +--- + +# 8. Performance Considerations + +- **CPU/Memory:** negligible — one additional short-lived test reusing an already-open browser context; no new heavyweight fixtures. +- **Rendering optimization:** relies on existing `waitForGameplayScene()` polling rather than fixed sleeps for the scene-transition assertion, avoiding both flakiness and unnecessary over-waiting. +- **Asset loading:** none new — Replay reuses already-loaded level assets (per `handleRetryOrNext`, `this.data.levels[level]` is already in memory; no network re-fetch expected). +- **Drag interaction optimization:** not exercised by this test (verifies canvas *renders* interactive content via `assertCanvasHasContent`, not a full drag-drop cycle) — acceptable per AC 4 ("fully interactive **and can be played**" is evidenced by canvas content + scene readiness; a full stone-drag re-validation would duplicate `tc-006-008-gameplay.spec.ts` coverage rather than add value). +- **Offline / low-end device considerations:** not in scope — Replay is a same-session, no-network-refetch transition; existing suite has no offline-mode test lane to extend. +- **Measurable expectation:** new test should add no more than ~3–5s to total suite runtime beyond the mandated 2s settle wait plus normal scene-transition polling (bounded by `Timeouts.sceneTransition` = 15s worst case). + +--- + +# 9. Risks + +| Risk | Type | Mitigation | +|---|---|---| +| TC_016 already clicks Map as its final step, potentially navigating away from Level End before TC_017 runs | Technical / sequencing | Resolve via §14 Open Question 1 before implementation — either confirm Map-click doesn't fully tear down state usable by TC_017, or (fallback) have TC_017 re-enter Level End via `triggerLevelEndScene` (Option B) if natural continuation proves unreliable. | +| `LevelEndScene.dispose()` (500ms after retry) racing the new `GameplayScene` construction could cause a flaky read of `selectedLevelNumber` if read too early | Regression / flakiness | Always call `waitForGameplayScene()` before reading `gameStateService` state (already sequenced this way in §7, step 4 before step 6). | +| Serial suite (`workers: 1`, `fullyParallel: false`) means a flaky/failing TC_017 blocks nothing after it (it's last) but a bug in it does not block earlier tests — low blast radius | Deployment / CI | No mitigation needed beyond normal review; failure isolated to end of suite. | +| README/TC-numbering drift (README already inconsistent between `TC_016`/`TC_0016`) | Documentation | Use `FTM_TC_017` in code (matching existing `FTM_TC_016` code convention) and `TC_0017` in the README table (matching the table's existing column convention) — consistent with current (if imperfect) precedent, not introducing a new inconsistency. | + +--- + +# 10. Acceptance Criteria Mapping + +| # | Acceptance Criterion | Implementation | Validation | Expected Outcome | +|---|---|---|---|---| +| 1 | Automate Replay Level flow using existing framework | New `tc-017-level-replay.spec.ts` via `registerTests(getPage)` pattern | Code review against existing isolated-spec conventions | Test file structurally indistinguishable from siblings | +| 2 | Replay restarts the same level successfully | Step 3 (click) + Step 6 (`selectedLevelNumber === 1` assertion) | `expect(restartedLevel).toBe(1)` | Assertion passes; fails loudly if `handleRetryOrNext` regresses to increment level | +| 3 | Gameplay loads correctly after replay | Step 4 (`waitForGameplayScene()`) | Playwright auto-retry assertion on `#canvas` + `#pause-button` | Passes within `Timeouts.sceneTransition` (15s) | +| 4 | Replayed level fully interactive, playable from beginning | Step 5 (`assertCanvasHasContent`) | Non-transparent pixel check on `#canvas` | Confirms stones re-rendered post-replay | +| 5 | Correct level context maintained | Step 6 | `selectedLevelNumber` read via `window.__ftm.gameStateService` | Equals pre-replay level (Level 2 / index `1`) | +| 6 | Integrated into existing FTM E2E suite | Registration in `ftm-assessment-survey-flow.spec.ts` after `tc016` | `npm run test:e2e` includes TC_017 in output | TC_017 appears in default suite run + HTML/JUnit report | +| 7 | Follows framework standards/helpers/conventions | Reuses `LevelEndPage`, `GameplayPage`, `assertCanvasHasContent`, `Timeouts` — zero new abstractions beyond one constant | Code review | No new page-object/helper duplication | +| 8 | Reliable, non-flaky in CI | Explicit waits (`waitForGameplayScene`, `waitForTimeout(replaySettleDelay)`) instead of arbitrary sleeps for state checks | 20-run CI flake check (see §13) | 0 flakes across ≥20 consecutive CI runs | + +--- + +# 11. Unit Testing + +This is an E2E-only change — no `src/**` production code is modified, so no new Jest unit tests are strictly required by this ticket. For completeness, if `src/scenes/levelend-scene/levelend-scene.spec.ts` is touched in a related future change, note the existing coverage already asserts the retry path publishes `SWITCH_SCENE_EVENT` with `SCENE_NAME_GAME_PLAY` (see `levelend-scene.spec.ts:308-312`) — this spec's E2E test is complementary, not duplicative, since it verifies the *browser-observable* result (scene actually renders, canvas actually re-populates) rather than the *event-publish* call, which the unit test already covers. + +- **Files to test:** none new. +- **Scenarios/edge cases/mocks:** n/a (no unit-level code change). +- **Coverage recommendation:** no change to current Jest coverage thresholds expected. + +--- + +# 12. End-to-End Testing + +**Happy path:** +- `FTM_TC_017`: Level End loaded (from TC_016) → 2s settle → click Replay → gameplay scene reloads → canvas has content → `selectedLevelNumber` unchanged (Level 2). + +**Regression scenarios:** +- Run full `npm run test:e2e` suite (TC_001–TC_017) to confirm no ordering/state regressions introduced by inserting TC_017 after TC_016. +- Run `npm run test:e2e:isolated` to confirm `tc-017-level-replay.spec.ts` doesn't silently depend on cross-file fixture state it can't get standalone (flagged in §14 Open Question 2). + +**Negative scenarios:** +- If `#levelend-retry-btn` is not rendered (would only happen for `currentLevel === 0` with passing stars, per `levelend-scene.ts:339-342`) — not applicable to the current suite (plays Level 2, `currentLevel === 1`, so Replay always renders per `levelend-scene.ts:330-337`), but document this as a precondition comment in the new spec so a future change to which level the orchestrator plays doesn't silently break the Replay button's visibility assumption. + +**Offline scenarios:** out of scope — no offline test lane exists in the current suite to extend. + +**Low-end device scenarios:** out of scope — Playwright suite runs a single fixed Chromium profile (`playwright.config.ts`); no device-emulation matrix exists to extend. + +**Performance validation:** confirm total added runtime (§8) via before/after comparison of `npm run test:e2e:report` duration. + +**Cross-browser/platform validation:** not applicable — suite is Chromium-only per `playwright.config.ts`. + +--- + +# 13. Rollout Strategy + +**Implementation order:** +1. Add `Timeouts.replaySettleDelay` constant. +2. Author `tc-017-level-replay.spec.ts`. +3. Register in orchestrator (`ftm-assessment-survey-flow.spec.ts`). +4. Update `e2e/tests/README.md` TC table. +5. Run locally (`npm run test:e2e`) and in isolation (`npm run test:e2e:isolated`) before opening a PR. + +**Deployment strategy:** standard PR → CircleCI `node/test` + `e2e-tests` jobs must pass before merge, per existing branch-gating rules in `.circleci/config.yml`. No feature flag needed (test-only change). + +**Rollback plan:** revert the PR; no production/runtime code is touched, so rollback carries zero user-facing risk. + +**Monitoring requirements:** watch the `e2e-tests` CircleCI job's HTML/JUnit report (already uploaded to S3) for the first several post-merge runs to catch any latent flake in the new test. + +**Success metrics:** TC_017 green on `main`/`develop` for the first 20 consecutive CI runs; no increase in overall `e2e-tests` job duration beyond the estimate in §8. + +--- + +# 14. Open Questions + +1. **Sequencing conflict:** `tc-016-level-completion.spec.ts` currently ends by **clicking Map** and asserting arrival at Level Selection — this navigates away from the Level End screen. Since `FTM_TC_017` is specified to run "after" TC_016 and needs the Level End screen still loaded, please confirm one of: + - (a) TC_016 should be left as-is, and TC_017 should independently re-enter Level End for Level 2 via the existing `triggerLevelEndScene(page, 3, 1, false)` helper (Option B in §4) rather than assuming natural continuation, **or** + - (b) TC_016's final "click Map" step should move to become the last step of TC_017 instead (Option A in §4), accepting a small edit to an existing, previously-signed-off test case. + This materially changes §6/§7 and should be confirmed before implementation begins. +2. Does `tc-017-level-replay.spec.ts` need to be independently runnable via `npm run test:e2e:isolated` (i.e., with its own setup to reach Level End without relying on TC_001–016 having already run in the same file), matching the "self-contained" description of the isolated suite in `e2e/tests/README.md`? Current isolated files (e.g. `tc-016`) appear to assume `getPage()` already reflects deep flow state, so this may be an existing pattern gap rather than one unique to this ticket. +3. Should the QA Test Case spreadsheet (linked in the ticket) be updated with the new `TC_0017` row as part of this ticket's Definition of Done, or tracked as a separate QA-doc task? +4. Is verifying `selectedLevelNumber` via `window.__ftm.gameStateService` (a debug/internal global) acceptable as the source of truth for AC 5, or is a DOM-visible signal preferred (none currently exists — would require a `src/` change, which is out of scope per the ticket's automation-only framing)?
