i18n smoke checklist

Manual verification to run before cutting a v0.4.0.x release. Automation covers generator internals + API endpoints (tests/test_i18n_generator.py, tests/test_api_i18n.py); this checklist covers the last-mile UI behavior that's impractical to script without a full E2E framework.

Pre-flight

• python scripts/i18n_diff.py — reports zero issues between en.ts and uk.ts (keys + placeholder parity).
• python scripts/i18n_lint.py — hardcoded-string candidate count matches docs/i18n_audit_baseline.json.
• python scripts/i18n_audit.py — no new hardcoded strings in recently-touched components.
• npx tsc --noEmit — clean on new files (pre-existing errors in Dashboard/Modules/etc are not this release's concern).
• npx vite build — completes without errors, UK chunk emits separately, index chunk ≤ 750 KB.

SPA — language switching (4 sample languages)

For each of en, uk, ru, ja:

1. Settings → Appearance → Language → click the tile.
2. Top-bar labels (Dashboard, Devices, Automations, Voice) switch within ~200 ms.
3. First-time auto-language banner (ru, ja) appears once — click "Got it", switch away, switch back → banner stays dismissed.
4. Safe-harbor: Settings sidebar still shows the Language tab label + native name in the new language.
5. Long-press logo (1.5 s) → "Reset UI to English?" modal appears — close without confirming, verify UI still in the selected language.

Wizard — language step (cold install)

Requires a fresh install (or manually sudo cp config/core.yaml.example config/core.yaml and restart core).

• Wizard step 1 shows all 16 languages grouped as "Fully translated" (2) and "Machine-translated (beta)" (14).
• Search box filters by both native name and ISO code.
• Selecting an auto-language shows the "β" badge + first-time banner.

Dashboard edit-mode gate

• Default: Settings → Users → Interface protection → edit_mode_pin is on.
• Dashboard → tap "Edit" → PIN modal appears.
• Enter correct PIN → enters edit mode; widget drag/drop works.
• Tap "Done" → exits edit mode without re-prompting.
• Toggle edit_mode_pin off → "Edit" enters directly, no PIN.
• Toggle kiosk_mode on → "Edit" prompts even when edit_mode_pin is off.

Navigation (B1)

• Top-bar links: Dashboard / Devices / Automations / Voice.
• Each route renders the corresponding module's settings iframe.
• Old URL /settings/system-modules/voice-core 302s to /voice.
• <768px viewport (browser devtools → mobile): bottom-nav appears, top-nav links collapse.

Module settings — i18n fetch

Pick 3 different modules (include voice-core as the pilot):

• Open settings iframe → labels are in the active UI language.
• Change UI language → iframe re-renders without page reload (widget-common.js posts lang_changed).
• Network tab shows GET /api/i18n/bundle/{module}?lang={lang} returning a merged bundle ≥ 30 keys.

TTS language-mismatch suggestion

• Current TTS voice is UK → switch UI to EN or PL → banner "Voice does not match interface" appears under LanguagePicker.
• If a matching installed voice exists: "Activate" button works, banner disappears.
• If no matching voice: banner points at voice downloads.
• Dismiss → next UI change to the same pair stays silent.
• Global opt-out checkbox → all future switches stay silent.

Visual theme

• Default dark theme paints a subtle gradient (not a flat black).
• Default light theme paints a subtle gradient (not a flat grey).
• Any wallpaper — widgets remain readable (backdrop-blur + 70% surface-color mix). Test on a contrasty wallpaper.

Regression (quick pass)

• Dashboard: wake word works, voice intent renders.
• Modules page: list, install, start/stop still work.
• Settings tabs: every sub-route loads without console errors.
• curl http://localhost/api/v1/health → "status": "ok".
