lorentz 5d87455e49 feat(04-02): rewrite mobile tickets list page with URL-synced filters, priority stripes, and IntersectionObserver infinite scroll 
Cherry-picked from 04-02 worktree (b27db7d, 4ba89a0). The full worktree merge
included unrelated regressions of phase 2/3 work — only the intended changes
(app/mobile/tickets/page.tsx + SUMMARY.md) were kept.

- Suspense wrapper for useSearchParams (Next.js 16 requirement)
- URL-synced filter state via router.replace
- TicketFilterStrip wired with controlled props
- Priority-stripe rows (border-l-4 with red/orange/amber/slate)
- IntersectionObserver infinite scroll + Load more fallback
- toast.error() in load catch blocks per D-21
- Empty states per D-20

phase provides
02-mobile-shell-more-drawer Mobile layout shell (HeaderBar, BottomNav) that the tickets page docks inside
app/mobile/tickets/page.tsx: fully wired mobile tickets list — URL-synced filters, priority-stripe rows, IntersectionObserver infinite scroll, skeleton load, D-20 empty states
added patterns
useSearchParams + Suspense boundary: Next.js 16 requirement for URL param hydration in client components
router.replace (not push) for filter URL sync: prevents back-button history pollution (D-05)
Cursor NOT in URL: fresh visits always start at page 1 (D-07)
IntersectionObserver with rootMargin 200px + Load more fallback for a11y (D-12/D-14)
toast.error() in BOTH loadFirst and loadMore catch blocks alongside setError (D-21)
Queue options derived from first-page tickets — no separate /api/mobile/queues endpoint
openTotal approximated as tickets.length + (hasMore ? 1 : 0) — precise count deferred
created modified
app/mobile/tickets/page.tsx
Default status [1, 8, 7] applied client-side when URL has no status param — matches server default and keeps URL clean on unfiltered visits
status='' in URL means explicit 'no status filter'; status absent means default [1, 8, 7]
Queue options built incrementally from first-page ticket data — acceptable for v1, no new endpoint needed
openTotal is tickets.length + (hasMore ? 1 : 0) — visible label reads 'N open tickets'; precision deferred until count endpoint exists
toast.error() always fires alongside setError in catch blocks per D-21

Phase 4 Plan 02: Mobile Tickets List Page Wiring Summary

Rewrote app/mobile/tickets/page.tsx with URL-synced Collapsible filter strip, priority-stripe rows, IntersectionObserver infinite scroll, Load-more fallback, skeleton loading, toast.error on failure, and D-20 empty states

Performance

  • Duration: 8 min
  • Completed: 2026-05-03T22:09:00Z
  • Tasks: 1 code task + 1 human-verify checkpoint (auto-approved)
  • Files modified: 1

Accomplishments

  • Replaced the 164-line page-based MobileTickets component end-to-end with a 310-line MobileTicketsPage (Suspense shell) + MobileTicketsInner (state machine)
  • Wired TicketFilterStrip (Plan 01) and TicketRowSkeleton (Plan 01) into the page
  • URL filter sync via useSearchParams + router.replace — all five params (q, status, priority, queue, mine) are round-trippable; reload hydrates filter state
  • Cursor-based infinite scroll via IntersectionObserver (rootMargin 200px) with a focusable Load more fallback button
  • Priority-stripe rows: border-l-4 + locked Tailwind classes border-red-500 / border-orange-400 / border-amber-400 / border-slate-300
  • Two D-20 empty states: "No tickets match your filters" (filtered) and "No tickets to triage right now" (unfiltered)
  • toast.error() in both loadFirst and loadMore catch blocks (D-21 compliance)
  • Removed priority dot (PRIORITY_DOT), switched title from line-clamp-2 to truncate (D-17 / UI-SPEC)

URL <-> Filter State Mapping

URL param Absent behavior Present value Component effect
q "" (no search) string Search input value; debounced 400ms
status Default [1, 8, 7] (Open + In Progress + Waiting) comma-separated ints Status chip selection
status= Empty string → no status filter [] All statuses shown
priority [] (no filter) comma-separated ints Priority chip selection
queue null (all queues) int Queue Select value
mine false 1 Assigned-to-me Switch

Default status [1, 8, 7] matches the server-side default — when no status param is present, both client and server show the same set of tickets without the URL being polluted with a status parameter.

Queue List Derivation

No /api/mobile/queues endpoint was added. Queue options are derived incrementally from ticket data seen in the first page load: queue_id + queue_label from each MobileTicket are deduped by id and sorted alphabetically. The Select control works correctly because it always receives the most recent set after first load. This is acceptable for v1; adding a dedicated queues endpoint is deferred.

Open Total Approximation

openTotal = tickets.length + (hasMore ? 1 : 0) — the visible label reads "N open tickets". When hasMore is false, this is exact. When hasMore is true, it reads as ">N" semantically (though the UI just shows the count). A precise count endpoint is deferred to a future phase.

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Restored Plan 01 route.ts from HEAD after worktree working-tree mismatch

  • Found during: Task 1 TypeScript check (errors: MobileTicket and MobileTicketListResponse not exported from route)
  • Issue: The working tree contained the legacy page-based route.ts rather than the cursor-paginated Plan 01 version. This is a consequence of the worktree reset — git HEAD had the Plan 01 route, but the working tree files were from the pre-reset state.
  • Fix: git checkout 422ea2bd -- app/api/mobile/tickets/route.ts to restore the Plan 01 cursor-paginated route with exported interfaces.
  • Files modified: app/api/mobile/tickets/route.ts (restored to Plan 01 state — not a new change)
  • Commit: Included in b27db7d (staged alongside page.tsx)

2. [Rule 1 - Bug] Fixed implicit any TypeScript error in initials avatar

  • Found during: Task 1 TypeScript check
  • Issue: t.assigned_to.split(' ').map(s => s[0]) — s was implicitly any in strict mode
  • Fix: Added explicit type annotation: .map((s: string) => s[0])
  • Files modified: app/mobile/tickets/page.tsx
  • Commit: b27db7d

Checkpoint Auto-approval

Task 2: Human-verify checkpoint — Auto-approved per auto-mode active in parent orchestration. ⚡ Auto-approved: mobile tickets list page with filter strip, priority stripes, infinite scroll, and URL sync.

Known Stubs

None — all data is fetched from live /api/mobile/tickets. No hardcoded values flow to UI rendering. Queue options are derived from real ticket data. The openTotal approximation is documented above and is intentional, not a stub.

Threat Flags

No new network endpoints, auth paths, file access patterns, or schema changes were introduced. The URL param threat mitigations documented in the plan's <threat_model> (T-04-07 through T-04-10) are implemented:

  • T-04-07: parseFilterFromSearch() runs parseInt + isNaN filter — non-numeric tokens silently dropped
  • T-04-09: Search debounced 400ms; other filters are discrete actions
