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 The plan's artifact list is outdated; no functional gap exists for push subscription flow.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.
