- [x] **MOB-02**: Sidebar collapses to a hamburger menu on mobile with smooth open/close animation
- [x] **MOB-02**: Sidebar collapses to a bottom tab bar on mobile with smooth navigation and More sheet for secondary items
- [x] **MOB-03**: Chat interface is fully functional on mobile — send messages, see streaming responses, scroll history
- [x] **MOB-04**: Portal installable as a PWA with app icon, splash screen, and service worker for offline shell caching
- [x] **MOB-05**: Push notifications for new messages when PWA is installed (or service worker caches app shell for instant load)

gaps:
- truth: "Streaming responses (word-by-word tokens) work on mobile"

| 9 | Back arrow returns to conversation list on mobile | VERIFIED | `mobile-chat-header.tsx:24-29` onBack callback; `chat/page.tsx:275` sets mobileShowChat=false |
| 10 | Desktop two-column chat layout is unchanged | VERIFIED | `chat/page.tsx:244-262` md:w-72 md:block classes preserved on sidebar panel |
| 11 | Chat input stays visible when iOS virtual keyboard opens | VERIFIED | `chat-window.tsx:266-269` keyboardOffset from useVisualViewport applied to input paddingBottom |
| 12 | Streaming responses (word-by-word tokens) work on mobile | FAILED | `chat-window.tsx:17-18` uuid() calls itself recursively — infinite recursion on send |

> NOTE: `app/actions/push.ts` and `gateway/routers/push.py` are listed in the plan frontmatter but were deliberately implemented differently. Push subscription management is handled via direct `fetch` in `push-permission.tsx` to `/api/portal/push/subscribe`, which is served by `shared/api/push.py` (consistent with all other API routers in this project). The plan's artifact list is outdated; no functional gap exists for push subscription flow. These are documentation mismatches, not code gaps.

### Requirements Coverage
| Requirement | Source Plan | Description | Status | Evidence |
|-------------|-------------|------------------------------------------------------------------------------|----------------|------------------------------------------------------------------|
| MOB-01 | 08-01 | All portal pages render correctly on mobile (320px–480px) and tablet | HUMAN NEEDED | Layout wiring verified; visual correctness requires browser test |
| MOB-02 | 08-01 | Sidebar collapses (spec: hamburger menu, impl: bottom tab bar) | VERIFIED* | Tab bar implemented — superior to spec'd hamburger; REQUIREMENTS.md text is stale |
| MOB-03 | 08-02 | Chat interface fully functional on mobile — send, stream, scroll history | FAILED | mobileShowChat toggle wired; MobileChatHeader present; BUT uuid() recursive bug in chat-window.tsx blocks message send in secure contexts |
| MOB-04 | 08-01 | Portal installable as PWA with icon, splash, service worker | VERIFIED | manifest.ts, sw.ts, all icons, next.config.ts withSerwist all confirmed |
| MOB-05 | 08-03 | Push notifications for new messages when PWA installed | VERIFIED | Full pipeline: PushPermission -> push.py -> 012 migration -> web.py trigger -> sw.ts handler |
| MOB-06 | 08-02 | All touch interactions feel native — no hover-dependent UI on touch devices | HUMAN NEEDED | `active:bg-accent` classes present on all interactive items; 44px tap targets in all components; needs real device confirmation |
> *MOB-02: REQUIREMENTS.md says "hamburger menu" — implementation delivers a bottom tab bar per the PLAN design. The tab bar is the intended and superior design; requirement text is stale documentation.

### Anti-Patterns Found
| File | Line | Pattern | Severity | Impact |
|-------------------------------------------------------|------|--------------------------------|----------|--------------------------------------------------------------------------|
| `packages/portal/components/chat-window.tsx` | 18 | `return uuid()` — recursive call | BLOCKER | Infinite recursion when `crypto.randomUUID` is available (all HTTPS + localhost). Chat messages never send; browser tab crashes or hangs. |
---
### Human Verification Required
#### 1. Responsive Layout at Multiple Viewports (MOB-01)
**Test:** Open Chrome DevTools, toggle device toolbar, test at 320px (iPhone SE), 768px (iPad), 1024px (iPad landscape). Navigate to Dashboard, Employees, Chat, Usage, and Billing pages.
**Expected:** No horizontal scrolling, no overlapping elements, readable text at all widths. Sidebar visible at 768px+, tab bar visible at 320px.
**Why human:** Visual layout correctness (overflow, overlap, text truncation) requires rendered browser output.
#### 2. Bottom Tab Bar Navigation and More Sheet (MOB-02)
**Test:** At 320px, tap each tab (Dashboard, Employees, Chat, Usage). Tap More — verify sheet slides up. Check with `customer_operator` role that Billing/API Keys/Users are hidden in the sheet.
**Expected:** Active indicator on tapped tab; correct page loads; More sheet shows RBAC-filtered items; LanguageSwitcher and push permission toggle visible.
**Why human:** Touch tap feedback, animation smoothness, and RBAC filtering in the rendered session context cannot be verified by static analysis.
#### 3. Mobile Chat Full-Screen Flow (MOB-03)
**Test:** At 320px, navigate to Chat. Tap a conversation — verify full-screen mode with back arrow header and agent name. After fixing the uuid() bug (see Gaps), send a message and verify streaming tokens appear word-by-word. Tap back arrow — verify return to list.
**Expected:** WhatsApp-style navigation; streaming tokens render incrementally; back arrow works.
**Why human:** Streaming animation and back navigation flow require browser runtime. The uuid() bug MUST be fixed first.
#### 4. PWA Installability (MOB-04)
**Test:** Open Chrome DevTools > Application > Manifest. Verify manifest loads with name=Konstruct, icons at 192/512/maskable, start_url=/dashboard, display=standalone. Check Application > Service Workers for registration.
**Expected:** Manifest loads without errors; service worker registered and active; Lighthouse PWA audit score >= 90.
**Why human:** PWA install flow requires a browser with HTTPS or localhost, Lighthouse, or Android device.
#### 5. Push Notifications (MOB-05)
**Test:** Open More sheet, tap bell icon, grant notification permission. Close the browser tab. Trigger an AI Employee response (via API or second browser window). Tap the push notification.
**Expected:** Notification appears on device; tapping notification opens the portal at the correct conversation URL.
**Why human:** Push notification delivery requires running backend services, VAPID keys, and a real browser push subscription. Cannot simulate with grep.
#### 6. Touch Interaction Native Feel (MOB-06)
**Test:** At 320px, tap all buttons, links, and interactive elements throughout the portal. Test tab bar items, More sheet links, chat send button, conversation list items.
**Expected:** Immediate visual feedback on tap (active state); no hover-stuck states; all targets reachable with a finger (>= 44px).
**Why human:** Touch interaction feel, hover-stuck detection, and tap target perception require a real touch device or touch simulation in DevTools.
---
### Gaps Summary
**One blocker gap, one documentation gap.**
**Blocker: Infinite recursion in `uuid()` (chat-window.tsx line 18)**
The `uuid()` helper function in `chat-window.tsx` was written to fall back to a manual UUID generator when `crypto.randomUUID` is unavailable (e.g., HTTP non-secure context). However, the branch that should call `crypto.randomUUID()` calls `uuid()` itself recursively. In any secure context (HTTPS, localhost), `crypto.randomUUID` is always available, so every call to `uuid()` immediately recurses infinitely — causing a stack overflow. Chat messages in the portal require `uuid()` to generate stable IDs for optimistic UI updates (lines 100, 148, 158, 198). The fix is one character: change `return uuid()` to `return crypto.randomUUID()` on line 18.
**Documentation gap: REQUIREMENTS.md MOB-02 text is stale**
The REQUIREMENTS.md describes MOB-02 as "hamburger menu" but the design (defined in the PLAN and implemented in the codebase) uses a bottom tab bar — a more native mobile pattern. This is a documentation-only mismatch; the codebase correctly implements the intended design. Updating REQUIREMENTS.md to say "bottom tab bar" would bring the documentation in sync with the actual implementation.
