# Phase 17: Code Review Fix Report

**Fixed at:** 2026-06-18T00:00:00Z
**Source review:** .planning/phases/17-ui-optimization-polish/17-REVIEW.md
**Iteration:** 1

**Summary:**
- Findings in scope: 15 (fix_scope: all — includes Info)
- Fixed: 15
- Skipped: 0

All fixes were verified with `tsc --noEmit` (clean) and `eslint --max-warnings 0`
(clean) on every touched file; the PWA also builds (`vite build` succeeds). A new
shared hook `apps/pwa/src/hooks/useIsPhone.ts` was created to back WR-05/IN-03.

## Fixed Issues

### WR-01: Modal dialogs declare `aria-modal="true"` but do not trap focus

**Files modified:** `apps/pwa/src/components/CredentialSheet.tsx`, `apps/pwa/src/components/SettingsSheet.tsx`, `apps/pwa/src/routes/AdminPage.tsx`
**Commit:** fb30800
**Applied fix:** Reused the existing `useFocusTrap(dialogRef)` hook (already used by EventForm/SeriesEditPrompt). Added a `dialogRef` + `onKeyDown={handleDialogKeyDown}` to every modal sheet that asserts `aria-modal="true"`: CredentialSheet, SettingsSheet, ChangePasswordSheet, LinkOidcSheet, and ResetPasswordSheet. Tab/Shift-Tab now cycle within the dialog instead of escaping to occluded background controls.

### WR-02: Admin tab strip keyboard nav is incomplete (no Home/End, no explicit wrap)

**Files modified:** `apps/pwa/src/routes/AdminPage.tsx`
**Commit:** f601c0c
**Applied fix:** Rewrote `handleTabKeyDown` to the full WAI-ARIA tabs pattern: ArrowLeft/Right now wrap around the ends using modular arithmetic over the `['members','settings']` order, and Home/End jump to the first/last tab.

### WR-03: Success toast does not re-announce repeated identical messages

**Files modified:** `apps/pwa/src/routes/AdminPage.tsx`
**Commit:** f601c0c
**Applied fix:** Changed toast state from `string | null` to `{ id: number; msg: string } | null` with a `showToast(msg)` helper that mints a fresh `id` (Date.now()) per call. The rendered toast `<div>` is now keyed on `toast.id` so an identical repeated message remounts and `aria-live` re-announces it; the auto-dismiss effect depends on the fresh object reference so the 3s timer restarts.

### WR-04: Toast `whiteSpace: nowrap` is a latent horizontal-overflow regression

**Files modified:** `apps/pwa/src/routes/AdminPage.tsx`
**Commit:** f601c0c
**Applied fix:** Removed `whiteSpace: 'nowrap'` from the toast style so a longer/localized message wraps within `maxWidth: 90vw` instead of overflowing `documentElement.scrollWidth` (which would trip the layout suite's no-horizontal-overflow rule).

### WR-05: `matchMedia(...)` read at render time does not react to resize/orientation

**Files modified:** `apps/pwa/src/hooks/useIsPhone.ts` (new), `apps/pwa/src/App.tsx`, `apps/pwa/src/components/CalendarShell.tsx`, `apps/pwa/src/components/SettingsSheet.tsx`, `apps/pwa/src/components/CredentialSheet.tsx`, `apps/pwa/src/routes/AdminPage.tsx`
**Commit:** a4a7438
**Applied fix:** Added a resize-aware `useMediaQuery`/`useIsPhone` hook backed by `matchMedia.addEventListener('change', …)`. Replaced all six synchronous `matchMedia('(max-width: 767px)')` render-time reads with `useIsPhone()`. Hook calls were placed before any early `return null` to respect the Rules of Hooks. Components now re-render when the 767px breakpoint is crossed (iPad rotation, desktop resize).

### WR-06: Timezone combobox `aria-activedescendant`/highlight can desync after filtering

**Files modified:** `apps/pwa/src/routes/AdminPage.tsx`
**Commit:** 1c0f357
**Applied fix:** Derived a clamped `tzActiveIndexClamped = Math.min(tzActiveIndex, max(0, filteredZones.length - 1))` in render and used it for `aria-activedescendant`, the Enter-to-commit lookup, and the visual highlight (`i === tzActiveIndexClamped`). ArrowUp/ArrowDown clamp the current index before moving so they never start from a stale position past the end of a freshly-shrunk list.
**Note:** Combobox interaction logic — recommend a quick manual/keyboard pass (type to filter, arrow, Enter) to confirm behavior.

### WR-07: Timezone combobox drops Tab-to-commit and relies on a fragile blur timeout

**Files modified:** `apps/pwa/src/routes/AdminPage.tsx`
**Commit:** 1c0f357
**Applied fix:** Added a `Tab` branch to the combobox `onKeyDown` that commits the highlighted option WITHOUT `preventDefault` (focus still advances to Save). Added an unmount cleanup effect that clears `tzBlurTimer`. Reduced the blur-close `setTimeout` from 120ms to 0ms now that options `preventDefault()` on `onMouseDown` (so a click never blurs the input first).
**Note:** Interaction logic — recommend a manual check that tabbing out of the open listbox commits the highlighted zone and that clicking an option still selects it.

### WR-08: `pwa:icons` script is non-portable and silently coupled to generated filenames

**Files modified:** `apps/pwa/scripts/copy-pwa-icons.mjs` (new), `apps/pwa/package.json`, `apps/pwa/vite.config.ts`
**Commit:** dd0b761
**Applied fix:** Replaced the five-`cp` Unix-only chain with a cross-platform Node script (`fs.copyFileSync`) that maps each generated filename to its stable manifest name and fails loudly with a named error if a generated file is missing (generator rename guard). Added a discoverability comment beside the manifest `icons` array in `vite.config.ts` pointing at the script's COPIES table.

### IN-01: `OidcRedirect` navigates as a render-phase side effect

**Files modified:** `apps/pwa/src/App.tsx`
**Commit:** a4a7438
**Applied fix:** Moved `window.location.replace('/api/login')` into a `useEffect(() => {...}, [])` so the navigation is no longer a render-phase side effect.

### IN-02: Inconsistent `exhaustive-deps` disables across sibling dialogs

**Files modified:** `apps/pwa/src/components/CredentialSheet.tsx`, `apps/pwa/src/components/SettingsSheet.tsx`
**Commit:** 3f4b7ea
**Applied fix:** Wrapped `handleClose` in `useCallback` in CredentialSheet and ChangePasswordSheet, added it to the Escape effect's dependency array, and removed the `// eslint-disable-line react-hooks/exhaustive-deps` comments — matching the LinkOidc/Reset sheet pattern.

### IN-03: `isPhone`/`phone` 767px check duplicated across ~6 sites

**Files modified:** (same as WR-05)
**Commit:** a4a7438
**Applied fix:** Resolved together with WR-05 — the single `useIsPhone()` hook now backs all call sites, and the `(max-width: 767px)` query lives in one place (`PHONE_MAX_QUERY` in the hook). The old standalone `isPhone()` helpers in App.tsx and CalendarShell.tsx were deleted.

### IN-04: Dead placeholder brand tokens retained

**Files modified:** `apps/pwa/src/styles/tokens.css`
**Commit:** 2317833
**Applied fix:** Removed the unused `--brand-logo-bg`, `--brand-logo-text`, and `--brand-app-name` declarations (verified via grep that nothing references them); left a short comment explaining the removal and that BrandSlot only reads `--brand-logo-size`/`--brand-logo-border-radius`.

### IN-05: Admin members-panel JSX has inconsistent indentation / stacked bottom margins

**Files modified:** `apps/pwa/src/routes/AdminPage.tsx`
**Commit:** 4bc1e2a
**Applied fix:** Ran Prettier (project `.prettierrc`) over AdminPage.tsx, normalizing the members-panel indentation and the rest of the file's drift; `prettier --check` now passes on the file. The stacked `marginBottom: var(--space-8)` on the last panel section was left intentionally — the review flagged it only as a minor cosmetic note, and changing section spacing risks a visual regression outside the finding's scope.

### IN-06: Toast and dialog `zIndex` overlap (300/301)

**Files modified:** `apps/pwa/src/routes/AdminPage.tsx`
**Commit:** f601c0c
**Applied fix:** Raised the toast `zIndex` from 300 to 400 so it always paints above sheet backdrops (300) and sheets (301), removing the DOM-order-dependent paint ambiguity.

### IN-07: `Intl.DateTimeFormat()` recomputed every render in the calendar-config path

**Files modified:** `apps/pwa/src/components/CalendarShell.tsx`, `apps/pwa/src/routes/AdminPage.tsx`
**Commit:** 11b6b36
**Applied fix:** Wrapped both `Intl.DateTimeFormat().resolvedOptions().timeZone` reads in `useMemo(…, [])` — `displayTimeZone` in CalendarShell (feeds the stable `useCalendarApp` config) and `detectedTz` in AdminPage.
