+## Current Test
+
+[awaiting human testing]
+
+## Tests
+
+### 1. Filter strip default-collapsed and expand/collapse
+expected: |
+  Open `/mobile/tickets` on iPhone 15 Pro emulation (393×852).
+  - On load: filter strip is collapsed (only "Filters" toggle and search visible)
+  - Tap "Filters" → strip expands smoothly revealing status chips, priority chips, queue Select, and "Assigned to me" Switch
+  - Tap "Filters" again → collapses
+result: [pending]
+
+### 2. URL deep-link hydration
+expected: |
+  - Navigate to `/mobile/tickets?priority=2&mine=1` directly
+  - Filters hydrate: "High" priority chip selected, "Assigned to me" toggled on
+  - Adjust a filter — URL updates via router.replace (no new history entry)
+  - Browser back exits the page rather than reverting the filter mutation
+result: [pending]
+
+### 3. IntersectionObserver infinite scroll
+expected: |
+  - Load page, scroll to bottom of first ~25 rows
+  - Next page (~25 more) auto-loads when last row is ~200px from viewport
+  - No double-fetch when scrolling fast
+  - When `nextCursor` is null, no further fetches occur
+result: [pending]
+
+### 4. Load more fallback button (accessibility)
+expected: |
+  - Tab key reaches the "Load more" button below the sentinel
+  - Press Enter or Space triggers the next page fetch
+  - Button hides when `hasMore` is false
+result: [pending]
+
+### 5. Priority stripe colors render correctly
+expected: |
+  - Critical (priority=1) row has a red left border (`border-red-500`)
+  - High (priority=2) → orange left border
+  - Medium (priority=3) → amber left border
+  - Low (priority=4) → slate left border
+  - Confirms Tailwind didn't purge dynamic priority classes
+result: [pending]
+
+### 6. Detail page header layout
+expected: |
+  - Tap a ticket row → navigate to `/mobile/tickets/[id]`
+  - Shell HeaderBar (Wulf mark + bell + avatar) renders at top
+  - Below it: new in-page header with back chevron + "Tickets" + breadcrumb "Tickets / #{number}" + external-link icon
+  - Tapping back chevron returns to list (preserving filter URL state)
+  - Tapping external-link icon opens desktop ticket page in new tab
+  - No double-border or visual overlap between the two header levels
+result: [pending]

+# Phase 4: Tickets Restyle Verification Report
+
+**Phase Goal:** A manager triages tickets on a phone with a collapsible filter bar that deep-links via URL, priority-coloured rows, and infinite scroll — and the detail page header matches the new shell.
+**Verified:** 2026-05-03T22:15:02Z
+**Status:** human_needed
+**Re-verification:** No — initial verification
+
+## Goal Achievement
+
+### Observable Truths (from Roadmap Success Criteria)
+
+| # | Truth | Status | Evidence |
+|---|-------|--------|----------|
+| 1 | Tickets page opens with filter strip collapsed; expanding reveals status, priority, queue, mine toggle; changing any filter updates the URL (deep link works on reload) | ✓ VERIFIED | `TicketFilterStrip` uses `useState(false)` as Collapsible default; `router.replace()` called in filter effect; `parseFilterFromSearch()` hydrates state from `useSearchParams()` on mount; `filterToSearch()` serializes all 5 params |
+| 2 | Each list row has a left-edge stripe matching priority (Critical/High/Medium/Low → red/orange/amber/slate) and shows ticket #, title, company, age, and assignee | ✓ VERIFIED | `PRIORITY_BORDER` record maps `{1: 'border-red-500', 2: 'border-orange-400', 3: 'border-amber-400', 4: 'border-slate-300'}`; `border-l-4` applied to Link wrapper; row renders `ticket_number`, `title`, `company_name`, `relTime(last_activity_date)`, initials avatar from `assigned_to` |
+| 3 | Single-tapping a row navigates to `/mobile/tickets/[id]` | ✓ VERIFIED | Each row is a `<Link href={/mobile/tickets/${t.id}}>` — native Next.js navigation |
+| 4 | Scrolling to the bottom auto-loads next ~25 rows (no Next button); a Load more fallback button is visible/focusable for accessibility | ✓ VERIFIED | `IntersectionObserver` with `rootMargin: '200px'` on `sentinelRef`; guard `loadingMore \|\| !hasMore`; focusable `<button aria-label="Load more tickets">` always rendered when `hasMore` |
+| 5 | Detail page header uses new shell styling (back chevron + breadcrumb); body remains largely unchanged | ✓ VERIFIED | Three-slot header: `ArrowLeft`+Tickets button (`router.back()`), `"Tickets / #" + ticket_number` breadcrumb, `ExternalLink` anchor to `/analyzer/ticket/{id}`; `TimelineCard`, `fmtDate`, `renderContent`, stats grid, description Collapsible, and timeline all preserved verbatim (D-19) |
+
+**Score:** 5/5 truths verified
+
+### Required Artifacts

+### Data-Flow Trace (Level 4)
+
+| Artifact | Data Variable | Source | Produces Real Data | Status |
+|----------|---------------|--------|--------------------|--------|
+| `app/api/mobile/tickets/route.ts` | `tickets` (array) | `postgresClient.query(SELECT ... FROM tickets ... WHERE ... LIMIT ...)` | Yes — live DB query with parameterized WHERE clause | ✓ FLOWING |
+| `app/mobile/tickets/page.tsx` | `tickets` state | `fetch('/api/mobile/tickets?...')` → `data.tickets` | Yes — fetches from the live route above | ✓ FLOWING |
+| `app/mobile/tickets/page.tsx` | `queueOptions` state | Derived from `data.tickets` first-page `queue_id + queue_label` fields | Yes — populated from real ticket data, not hardcoded | ✓ FLOWING |
+
+### Behavioral Spot-Checks
+
+Server must be running for live API checks. Performed static verification only.
+
+| Behavior | Check | Result | Status |
+|----------|-------|--------|--------|
+| API returns cursor-based shape | `grep -q "nextCursor" app/api/mobile/tickets/route.ts` | Found: `return NextResponse.json({ tickets, nextCursor, hasMore } satisfies MobileTicketListResponse)` | ✓ PASS |
+| TypeScript compiles without errors (all phase 4 files) | `npx tsc --noEmit --pretty 2>&1 \| grep -E "app/mobile/tickets\|app/api/mobile/tickets\|components/mobile/Ticket"` | No output — no type errors | ✓ PASS |
+| Full TypeScript build is clean | `npx tsc --noEmit --pretty 2>&1` | No output — zero errors project-wide | ✓ PASS |
+| API module exports count | `grep -c "export interface" app/api/mobile/tickets/route.ts` | 2 (MobileTicket + MobileTicketListResponse) | ✓ PASS |
+| Live API smoke | Requires running dev server — skip | N/A | ? SKIP |
+
+### Requirements Coverage
+
+| Requirement | Source Plan | Description | Status | Evidence |
+|-------------|------------|-------------|--------|----------|
+| TICK-01 | 04-01, 04-02 | Collapsible filter strip at top, default collapsed | ✓ SATISFIED | `TicketFilterStrip` with `useState(false)` Collapsible default; rendered in `page.tsx` |
+| TICK-02 | 04-01, 04-02 | Filter state syncs to URL query string for deep-linking | ✓ SATISFIED | `router.replace()` called on every filter change; `parseFilterFromSearch()` hydrates on mount; 5 URL params (`q`, `status`, `priority`, `queue`, `mine`) round-trip |
+| TICK-03 | 04-02 | Left-edge color stripe by priority; row shows ticket #, title, company, age, assignee | ✓ SATISFIED | `PRIORITY_BORDER` record + `border-l-4`; row renders all 5 fields |
+| TICK-04 | 04-02 | Single-tap on row opens detail page | ✓ SATISFIED | Row wrapped in `<Link href="/mobile/tickets/${t.id}">` |
+| TICK-05 | 04-01, 04-02 | Cursor-based infinite scroll (~25/page) via IntersectionObserver | ✓ SATISFIED | API uses opaque base64 cursor, server limit 25; `IntersectionObserver` with `rootMargin: '200px'` triggers `loadMore()` |
+| TICK-06 | 04-02 | "Load more" fallback button for accessibility | ✓ SATISFIED | `<button aria-label="Load more tickets">` always rendered when `hasMore`; disabled during `loadingMore` |
+| TICK-07 | 04-03 | Detail page header reskinned to match new shell; body largely unchanged | ✓ SATISFIED | Three-slot header replaces legacy Back button; `TimelineCard`, stats grid, description, timeline unchanged (D-19) |
+
+All 7 TICK requirements are satisfied. No orphaned requirements.
+
+### Anti-Patterns Found
+
+| File | Line | Pattern | Severity | Impact |
+|------|------|---------|----------|--------|
+| `app/mobile/tickets/[id]/page.tsx` | 59–70 | "placeholder" word in comment (`// Step 1: convert ... placeholder`) | ℹ Info | Part of `renderContent` HTML-link extractor — internal algorithm comment, not a stub. Legacy code preserved per D-19. |
+| `components/mobile/TicketFilterStrip.tsx` | 159 | `<SelectValue placeholder="All queues" />` | ℹ Info | shadcn `Select` placeholder text — correct use of the component, not a data stub |
+| `components/mobile/TicketRowSkeleton.tsx` | 4 | "skeleton placeholder row" in comment | ℹ Info | Intentional design — this component IS a placeholder by purpose (D-21) |
+
+No blockers or warnings found. All info-level matches are correct-use patterns, not stubs.
+
+### Regression Verification
+
+| Check | Status | Evidence |
+|-------|--------|----------|

+
+All 21 locked decisions honored.
+
+### Human Verification Required
+
+**6 items require browser/device testing:**
+
+#### 1. Filter Strip Collapse/Expand
+
+**Test:** Open `/mobile/tickets` on a phone-width viewport (real device or Chrome DevTools iPhone 15 Pro emulation). Observe the filter strip state on initial load. Tap the "Filters" button.
+**Expected:** Strip is collapsed on load (only search input + "Filters" button visible). Tapping "Filters" smoothly animates open to show status chips (Open / In Progress / Waiting), priority chips (Critical / High / Medium / Low), queue Select, and Assigned-to-me Switch.
+**Why human:** Collapsible animation and touch interaction require rendered DOM.
+
+#### 2. URL Deep-Link Round-Trip
+
+**Test:** Navigate to `/mobile/tickets?priority=2`. Reload the page. Use the browser back button after changing a filter.
+**Expected:** Filter strip hydrates with "High" chip selected; list shows only priority-2 tickets. Back button exits `/mobile/tickets` entirely (does not revert to previous filter state — `router.replace` not `router.push`).
+**Why human:** `router.replace` history behavior requires a running Next.js app.
+
+#### 3. IntersectionObserver Infinite Scroll
+
+**Test:** On `/mobile/tickets` (with enough tickets in the DB to require multiple pages), scroll to the bottom.
+**Expected:** As the last row approaches the viewport (~200px ahead), the next 25 tickets load automatically and append — no page navigation, no URL change, a small spinner appears briefly.
+**Why human:** IntersectionObserver `rootMargin` behavior requires a rendered browser.
+
+#### 4. Load More Keyboard Accessibility
+
+**Test:** With a mouse or keyboard, Tab to the "Load more" button when it is visible. Press Enter.
+**Expected:** Button is focusable; pressing Enter/Space triggers the next page fetch identically to clicking.
+**Why human:** Focus order and keyboard activation require rendered browser.
+
+#### 5. Priority Stripe Colors Rendered
+
+**Test:** Confirm visible priority-colored borders on rows across all four priority values.
+**Expected:** Priority 1 → red left border, priority 2 → orange, priority 3 → amber, priority 4 → slate. Colors must match the locked D-15 Tailwind classes (not the legacy yellow for medium).
+**Why human:** Tailwind purge in production builds could drop dynamic class references unless all four strings appear literally — visual confirmation is needed to catch any purge regression.
+
+#### 6. Detail Page Three-Slot Header Layout
+
+**Test:** Navigate to any `/mobile/tickets/[id]` page. Confirm the header structure from top to bottom.
+**Expected:** Shell HeaderBar (Wulf wordmark + Bell + avatar) at top → below it the in-page three-slot header (ArrowLeft + "Tickets" on left, "Tickets / #TXXXXXX" centered, ExternalLink icon on right with a bottom border separating it from the body) → below that the unchanged badges + title + stats + description + timeline. No double border, no visual overlap with the shell.
+**Why human:** Nested sticky/fixed layout and `-mx-4` bleed technique require a rendered browser to confirm correct visual output.
+
+---
+
+## Summary
+
+All five roadmap success criteria are satisfied end-to-end in the codebase. All 7 TICK requirements (TICK-01 through TICK-07) are evidenced. All 21 locked decisions (D-01 through D-21) are honored. TypeScript compiles cleanly project-wide. No prior-phase regressions detected.
+
+The phase is blocked from `passed` status only by 6 items that require a running browser for validation: filter expand/collapse animation, URL history semantics, IntersectionObserver triggering, keyboard focus, priority stripe visual rendering, and the two-level header layout on the detail page.
