+<objective>
+Visual verification of the complete planning threads feature. Confirm all user-facing behaviors work end-to-end in the browser.
+
+Purpose: Catch visual, interaction, and integration issues that automated tests cannot detect.
+
+Output: Confirmation that Phase 2 requirements are met from the user's perspective.

+  <name>Task 1: Visual verification of complete planning threads feature</name>

+  <action>
+    Verify the complete planning threads feature in the browser.
+
+    What was built: Tab navigation between My Gear and Planning views, thread CRUD with card-based list, candidate CRUD with slide-out panel, and thread resolution flow with confirmation dialog.
+
+    Start the dev server if not running: `bun run dev`
+    Open http://localhost:5173
+
+    **1. Tab Navigation (THRD-01)**
+    - Verify "My Gear" and "Planning" tabs are visible
+    - Click "Planning" tab -- URL should update to /?tab=planning
+    - Click "My Gear" tab -- should show your gear collection
+    - Verify top navigation bar is always visible
+
+    **2. Thread Creation (THRD-01)**
+    - On the Planning tab, create a new thread (e.g. "Helmet")
+    - Verify it appears as a card in the thread list
+    - Card should show: name, "0 candidates", creation date
+    - Create a second thread to verify list ordering (most recent first)
+
+    **3. Candidate Management (THRD-02, THRD-03)**
+    - Click a thread card to open thread detail page
+    - Verify back navigation to Planning tab works
+    - Add a candidate via slide-out panel with: name, weight, price, category, notes, product URL
+    - Verify candidate appears as a card in the grid
+    - Add 2-3 more candidates with different prices
+    - Verify the thread card on the list page shows updated candidate count and price range
+    - Edit a candidate (change price or name) -- verify changes saved
+    - Delete a candidate -- verify confirmation dialog and removal
+
+    **4. Thread Resolution (THRD-04)**
+    - On a thread with multiple candidates, click "Pick Winner" on one
+    - Verify confirmation dialog: "Pick [X] as winner? This will add it to your collection."
+    - Confirm the resolution
+    - Verify thread disappears from active thread list
+    - Toggle "Show archived" -- verify resolved thread appears (visually distinct)
+    - Switch to "My Gear" tab -- verify the winning candidate appears as a new collection item with correct data
+
+    **5. Visual Consistency**
+    - Thread cards match the visual style of item cards (same shadows, rounded corners)
+    - Candidate cards match item card style
+    - Pill/chip tags are consistent with existing tag pattern
+    - Slide-out panel for candidates looks like the item panel
+    - Empty states are present and helpful
+  </action>
+  <verify>User confirms all checks pass by typing "approved"</verify>
+  <done>All four THRD requirements verified by user in browser. Visual consistency confirmed. Resolution flow works end-to-end.</done>
+</task>
+
+</tasks>
+
+<verification>
+User confirms all four THRD requirements work visually and interactively.

+
+<success_criteria>
+- All four THRD requirements verified by user in browser
+- Visual consistency with Phase 1 collection UI
+- Resolution flow creates item and archives thread correctly
+- No regressions to existing gear collection functionality
+</success_criteria>
