- TourDetailPage: MapTourBounds chỉ fitBounds 1 lần cho mỗi lần dữ liệu lộ trình thay đổi thực sự (theo locKey). Nếu người dùng đã pan/zoom rồi thì không refit khi data reload.
- TourNavigationPage: FitBounds chỉ chạy khi người dùng CHƯA tương tác (hasInteractedRef). Sau khi người dùng pan/zoom/drag, bản đồ giữ nguyên vị trí.
- Cả hai bản đồ đều tôn trọng vị trí người dùng đã chọn, không reset về mặc định khi có thay đổi dữ liệu phụ.

-# To AI Agent: Complete Component Relocation - Move Navigation Tabs to Top Header and Fix Button Text Wrapping
-
-## 1. Context & Structural Defects Analysis
-We are fixing a persistent UI layout failure on the mobile view (`yotrip.labz.io.vn`) as highlighted in the annotated screenshot `image_c61225.png`:
-
-- **Component Misplacement (Lower Red Box):** The sub-navigation tabs (`Lộ trình`, `Chi phí`, `Ảnh`, `Trò chuyện`...) are currently detached and floating erratically in the middle of the chat history viewport, overlapping message bubbles.
-- **Empty Empty Top Gap (Upper Red Box):** There is an empty dark/blank bar container sitting directly below the Main Tour Title Header ("Hoa vàng cỏ xanh 20...").
-- **Text Wrapping Bug:** The labels on the floating navigation items are wrapping onto multiple lines (e.g., `Lộ\ntrình`, `Chi\nphí`), ruining the horizontal tab presentation.
-
----
-
-## 2. Refactoring Objectives
-1. **DOM Relocation:** Completely extract the Sub-Navigation Tabs out of the chat message block. Relocate and mount it directly into the upper red box zone so it sits flush immediately underneath the Main Tour Header.
-2. **Text & Width Optimization:** Enforce strict styles on the tab container so that all navigation buttons adjust dynamically to fit within the viewport width. The button text names **MUST NOT** wrap down to a new line (`white-space: nowrap`).
-
----
-
-## 3. Targeted Fix Instructions
-
-### Step 1: Correct the DOM / React Component Tree Hierarchy
-Ensure the navigation component sits inside the sticky top layout zone, completely separated from the scrollable chat list container:
-
-```html
-<div class="chat-viewport-wrapper">
-  
-  <div class="fixed-top-header-block">
-    <header class="main-tour-header">
-      </header>
-
-    <nav class="sub-navigation-tabs">
-      <button class="nav-tab-item">Lộ trình</button>
-      <button class="nav-tab-item">Chi phí</button>
-      <button class="nav-tab-item">Ảnh</button>
-      <button class="nav-tab-item active">Trò chuyện</button>
-      <button class="nav-tab-item">Thành viên</button>
-      <button class="nav-tab-item">Cài đặt</button>
-    </nav>
-  </div>
-
-  <main class="chat-messages-scroll-area">
-    </main>
-
-</div>
-
-### Step 2: Apply CSS/Tailwind Rules for Button Shrinkage & Single-Line Restraints
-Apply these structural adjustments to make sure the tabs fill the screen width evenly without line breaks:
-
-/* Container for header components stacked on top */
-.fixed-top-header-block {
-  display: flex !important;
-  flex-direction: column !important;
-  width: 100% !important;
-  position: sticky !important;
-  top: 0 !important;
-  z-index: 50 !important;
-  background-color: #ffffff;
-}
-
-/* FIX: Ensure tabs fit inside the viewport layout cleanly */
-.sub-navigation-tabs {
-  display: flex !important;
-  width: 100% !important;
-  margin: 0 !important;
-  padding: 4px 8px !important; /* Tight padding to utilize screen real estate */
-  border-radius: 0 !important;
-  box-shadow: none !important;
-  border-bottom: 1px solid #e5e7eb;
-  background-color: #ffffff;
-  
-  /* Distribute items evenly across the width */
-  justify-content: space-between !important; 
-  align-items: center !important;
-}
-
-/* FIX: Absolute enforcement of no word-wrapping on buttons */
-.nav-tab-item {
-  display: flex !important;
-  flex-direction: column !important; /* Stack icon and text if applicable */
-  align-items: center !important;
-  justify-content: center !important;
-  flex: 1 1 0% !important;         /* Allow dynamic even shrinkage */
-  min-width: 0 !important;          /* Overcomes default flex minimums */
-  
-  /* Text layout fixes */
-  white-space: nowrap !important;   /* PREVENT TEXT FROM WRAPPING TO NEW LINE */
-  font-size: 11px !important;       /* Scaled down to prevent out-of-bounds clipping */
-  padding: 4px 2px !important;
-  text-align: center !important;
-}
-
-/* Handle icon sizes inside tabs if applicable */
-.nav-tab-item svg, .nav-tab-item i {
-  font-size: 16px !important;
-  margin-bottom: 2px !important;
-}
-
-## 4. Verification Check for AI Agent
-[ ] Verify that the navigation row is no longer hovering over the chat text bubble flow.
-
-[ ] Confirm there is zero dead space or black margin layers between the tour header and the navigation buttons.
-
-[ ] Inspect text elements for words like "Lộ trình" and "Chi phí"—they must read completely on a single line horizontally.

+# To AI Agent: Implement Smart Date-Based Accordion Auto-Expansion and Smooth Viewport Auto-Scroll
+
+## 1. Context & UI/UX Requirements
+We are enhancing the routing UX between `MemberDashboard.tsx` and `ItineraryTimeline.tsx` based on `image_cc31a4.png`.
+
+### Functional Specifications:
+1. **Date-Matching Evaluation:** When a user clicks "Chi tiết hành trình" on a tour card, calculate if the current user system local date falls inside any Stage/Leg timeline block.
+2. **Auto-Expansion State:** On timeline page load, the matched Leg accordion must be expanded by default (`expandedStageId === leg.id`).
+3. **Smart Auto-Scroll Layout:** The viewport must smoothly auto-scroll so that the expanded Leg's title bar lands **exactly below the sticky navigation tab bar** ("Lộ trình", "Chi phí", etc.), making it fully visible at the top of the viewport without layout clipping.
+
+---
+
+## 2. Technical Architecture & Layout Constraints
+
+- **The Sticky Header Challenge:** Since the top navigation tab bar uses sticky/fixed positioning, a naive `scrollIntoView({ block: 'start' })` will cause the Leg's title to crawl *underneath* the tabs, hiding it.
+- **The Solution:** We will inject a dynamic CSS scroll-margin-top parameter (`scroll-mt-[70px]` or matching header height) on each Leg container, and trigger a minor delayed layout effect pool using a React `setTimeout` to wait for the DOM accordion expansion reflow before pulling the scroll trigger.
+
+---
+
+## 3. Code Refactoring Blueprint
+
+### Step 1: Update Navigation Payload Handler in Dashboard Component
+Ensure the `MemberDashboard.tsx` accurately packages the matched target identifier into the client route state bucket:
+
+```typescript
+import { useNavigate } from 'react-router-dom';
+
+const navigate = useNavigate();
+
+const handleNavigateToItinerary = (tour: any) => {
+  let targetLegId = null;
+
+  if (tour?.legs && tour.legs.length > 0) {
+    const today = new Date();
+    today.setHours(0, 0, 0, 0);
+
+    for (const leg of tour.legs) {
+      const rawStart = leg.startDate || leg.plannedStart || leg.date;
+      const rawEnd = leg.endDate || leg.plannedEnd || leg.date;
+
+      if (rawStart) {
+        const startBound = new Date(rawStart);
+        startBound.setHours(0, 0, 0, 0);
+
+        const endBound = rawEnd ? new Date(rawEnd) : new Date(rawStart);
+        endBound.setHours(23, 59, 59, 999);
+
+        if (today >= startBound && today <= endBound) {
+          targetLegId = leg.id;
+          break;
+        }
+      }
+    }
+
+    if (!targetLegId) {
+      targetLegId = tour.legs[0].id; // Fallback to Chặng 1 if out of tour bounds
+    }
+  }
+
+  navigate(`/tour/${tour.id}`, { 
+    state: { defaultExpandedLegId: targetLegId, shouldScrollToTarget: true } 
+  });
+};
+
+### Step 2: Inject Safe Identifiers and Scroll Margin inside ItineraryTimeline
+Locate the top-level outer container div of each Leg item inside the timeline loop (currentTour.legs.map). Assign a unique id and a scroll margin class utility:
+
+{currentTour.legs.map((leg: any, legIdx: number) => (
+  <div 
+    key={leg.id}
+    id={`leg-anchor-node-${leg.id}`}
+    /* CRITICAL: scroll-mt-[70px] leaves a 70px buffer space at the top. 
+      Adjust '70px' to match the exact height of your white Tour Navigation Tabs bar!
+    */
+    className="scroll-mt-[70px] transition-all w-full mb-4"
+  >
+    {/* Accordion Header Title ("Chặng 2: Dạo chơi ở xứ hoa vàng...") */}
+    <div className="flex items-center justify-between ...">
+       ...
+    </div>
+  </div>
+))}
+
+### Step 3: Implement Lifecycle Interaction Trigger Engine
+Inside ItineraryTimeline.tsx, listen to the passed history route parameters. Set the state, then handle the async smooth scrolling action:
+
+import { useLocation } from 'react-router-dom';
+
+const location = useLocation();
+const [expandedStageId, setExpandedStageId] = useState<string | null>(null);
+
+useEffect(() => {
+  if (location.state?.defaultExpandedLegId) {
+    const targetId = location.state.defaultExpandedLegId;
+    
+    // 1. Instantly trigger the accordion state layout expansion
+    setExpandedStageId(targetId);
+
+    // 2. Schedule a deferred macro-task callback to allow DOM re-renders to finish
+    if (location.state?.shouldScrollToTarget) {
+      const scrollTimer = setTimeout(() => {
+        const targetElement = document.getElementById(`leg-anchor-node-${targetId}`);
+        if (targetElement) {
+          targetElement.scrollIntoView({ 
+            behavior: 'smooth', 
+            block: 'start' 
+          });
+        }
+        
+        // Clear history router state token flags to prevent repeating scroll on subsequent reload shifts
+        window.history.replaceState({}, document.title);
+      }, 150); // 150ms ensures smooth accordion height deployment transition finishes
+
+      return () => clearTimeout(scrollTimer);
+    }
+  } else if (currentTour?.legs && currentTour.legs.length > 0 && !expandedStageId) {
+    setExpandedStageId(currentTour.legs[0].id);
+  }
+}, [location.state, currentTour]);
+
+## 4. Quality Control & Acceptance Verification
+[ ] Date Matching Accuracy: Set today's date context matching a target Leg configuration profile. Tap the transition interface button from dashboard. The page must route directly and expand the target container block node.
+
+[ ] Flush Viewport Ceiling Test: The animated target header segment node must slide upwards smoothly. It must lock positions cleanly right below the lowest baseline layer shadow boundary of the Tab Controller without passing behind it.
+
+[ ] State Cleanliness Check: Refreshing or navigating back and forth within the active Timeline panel after the initial landing should not lock or force layout views to keep jumping scroll heights automatically.

+# Enhancement Summary: Tag Selection & Photo Filtering
+
+## Overview
+Successfully enhanced the travel planning application with improved photo tagging UI and photo filtering capabilities on the explore map.
+
+## Changes Implemented
+
+### 1. Enhanced TagSelectModal Component ✅
+**File**: `frontend/src/components/TagSelectModal.tsx`
+
+**Features Added**:
+- **Image Preview**: Shows the uploaded photo at the top of the modal (max-height: 192px, with rounded corners)
+- **Custom Tag Input**: Text input with "Nhập thẻ mới..." placeholder
+- **Add Custom Tags**: Button and Enter key support to add user-defined tags
+- **Remove Custom Tags**: Trash icon on hover to delete custom tags
+- **Visual Feedback**: Selected tags highlighted in different colors (blue for predefined, emerald for custom)
+- **Summary Section**: Displays count and list of all selected tags before confirmation
+
+**UI Improvements**:
+- Sticky header and footer for easy access
+- Separate sections for predefined tags and custom input
+- Max-height with scrolling for long tag lists
+- Smooth animations and transitions
+
+### 2. LandingPage Integration ✅
+**File**: `frontend/src/pages/LandingPage.tsx`
+
+**Updates**:
+- Added `photoPreviewUrl` state for temporary preview image
+- Created object URL using `URL.createObjectURL()` when file is selected
+- Pass preview URL to TagSelectModal component
+- Proper cleanup with `URL.revokeObjectURL()` on modal close or after upload
+- Included custom tags in upload formData as JSON
+
+**State Management**:
+```typescript
+const [photoPreviewUrl, setPhotoPreviewUrl] = useState<string>('');
+```
+
+### 3. ExploreMap Photo Tag Filtering ✅
+**File**: `frontend/src/pages/ExploreMap.tsx`
+
+**Features Added**:
+- **Photo Tag Filter State**: `selectedPhotoFilterTags` for tracking active filters
+- **Available Photo Tags**: `availablePhotoTags` computed from all public photos' metadata
+- **Enhanced Filter Dropdown**: Two-section filter UI:
+  - **Tour Section (🧳 Chuyến đi)**: Existing tour tags (single selection)
+  - **Photo Section (📸 Ảnh công khai)**: Photo tags from uploads (multiple selection)
+- **Filtering Logic**: `groupedPhotos` useMemo filters photos based on selected tags
+- **Dynamic Tag Population**: Photo tags automatically extracted from `photo.metadata.tags`
+
+**Filtering Behavior**:
+- Multiple photo tags can be selected simultaneously
+- Photos matching ANY selected tag are displayed (OR logic)
+- "Tất cả" button clears photo filters
+- Filter is independent from tour tag filtering
+
+## Technical Details
+
+### Tag Storage
+- Backend stores tags in `photo.metadata.tags` as JSON array
+- No database schema changes required
+- Flexible for custom tags without pre-definition
+
+### Frontend State Management
+```typescript
+// State
+const [selectedPhotoFilterTags, setSelectedPhotoFilterTags] = useState<string[]>([]);
+
+// Computed
+const availablePhotoTags = React.useMemo(() => {
+  const tagsSet = new Set<string>();
+  publicPhotos.forEach(photo => {
+    const tags = photo.metadata?.tags as string[] | undefined;
+    if (Array.isArray(tags)) {
+      tags.forEach(tag => tagsSet.add(tag));
+    }
+  });
+  return Array.from(tagsSet).sort();
+}, [publicPhotos]);
+
+// Filtered Results
+const groupedPhotos = React.useMemo(() => {
+  let filteredPhotos = publicPhotos;
+  if (selectedPhotoFilterTags.length > 0) {
+    filteredPhotos = publicPhotos.filter((photo) => {
+      const photoTags = photo.metadata?.tags as string[] | undefined;
+      if (!Array.isArray(photoTags)) return false;
+      return selectedPhotoFilterTags.some(tag => photoTags.includes(tag));
+    });
+  }
+  // ... grouping and sorting logic
+}, [publicPhotos, selectedPhotoFilterTags]);
+```
+
+## Testing Results
+
+### Verified Functionality
+✅ Image preview displays in TagSelectModal  
+✅ Custom tag input accepts user text  
+✅ Custom tags can be added with button or Enter key  
+✅ Custom tags can be removed with trash icon  
+✅ All selected tags display in summary  
+✅ Photo tag filtering works on ExploreMap  
+✅ Multiple photo tags can be selected  
+✅ "Tất cả" button clears filters  
+✅ Docker build successful (0 errors)  
+✅ All services running healthy  
+
+### Build Status
+- Frontend build: ✅ Success
+- Backend build: ✅ Success  
+- Container deployment: ✅ All 4 services running
+- Browser testing: ✅ Filter dropdown functional
+
+## User Workflow
+
+### Photo Upload with Tags
+1. User clicks "Chụp ảnh" button
+2. Selects image from device
+3. Image is displayed in TagSelectModal preview
+4. User selects predefined tags from 11 categories
+5. User can add custom tags in textbox
+6. Confirms and photo is uploaded with all tags
+7. Tags stored in database for filtering
+
+### Photo Discovery with Filtering
+1. User navigates to "Khám phá" (Explore)
+2. Clicks filter button to open dropdown
+3. Sees available photo tags from community uploads
+4. Selects one or more tags to filter
+5. Map refreshes showing only photos with selected tags
+6. Clear selection with "Tất cả" button to see all photos again
+
+## Files Modified
+- ✅ `frontend/src/components/TagSelectModal.tsx` - Enhanced with preview and custom tags
+- ✅ `frontend/src/pages/LandingPage.tsx` - Integration with preview URL
+- ✅ `frontend/src/pages/ExploreMap.tsx` - Photo tag filtering implementation
+
+## Browser Compatibility
+- Modern browsers with ES6+ support
+- Tested on latest Chrome/Firefox/Safari
+- Mobile responsive design with touch support
+
+## Performance Considerations
+- Photo tag extraction done in useMemo (cached)
+- Filter operations are optimized with Set for uniqueness
+- Lazy filtering applied only to grouped photos
+- No additional API calls needed (uses existing photo data)
+
+## Future Enhancements

+# To AI Agent: Fix Infinite Re-render Loop and Flickering "ĐANG TÌM ĐƯỜNG TỐI ƯU..." Label
+
+## 1. Context & Layout Bug Analysis
+We are resolving a critical performance and UI bug inside the Map routing engine interface (`image.png`):
+- **The Issue:** The floating loading indicator badge reading `"ĐANG TÌM ĐƯỜNG TỐI ƯU..."` keeps flashing, flickering, or appearing and disappearing in an infinite execution loop.
+- **Root Cause:** This is caused by a broken React lifecycle loop. Every time the map triggers a directions route query, it toggles a loading state variable (`isSearching: true`). Once the route loads, the state updates (`isSearching: false`), forcing a component re-render. If the coordinates object (`origin`, `destination`) or the map instance ref inside the `useEffect` dependency array changes its reference pointer on every render, the hook fires *again*, creating an endless loop of API fetching and component flashing.
+
+---
+
+## 2. Technical Execution Strategy
+To terminate this flickering cycle, we must enforce a strict guard rail on the network/calculation trigger pipeline:
+1. **Coordinate Reference Stability:** Deconstruct the input latitude/longitude objects into raw primitive string values (e.g., `origin.lat`, `origin.lng`) inside the hook dependency array to avoid object reference mutations triggering re-renders.
+2. **Locking Ref Mechanism:** Implement a mutable React tracking reference (`const queryInProgress = useRef(false)`) to lock the execution window. If a fetch operation is active, block subsequent duplicate queries from firing.
+3. **Clean Loading State Termination:** Turn off the search state flag explicitly only *after* the route geometry polyline has completely finished rendering onto the map viewport layout.
+
+---
+
+## 3. Code Refactoring Blueprint
+
+Locate your map navigation layer or modal component (e.g., `LocationNavigationModal.tsx`) and refactor the execution lifecycle loop as defined below:
+
+```typescript
+import React, { useEffect, useState, useRef } from 'react';
+
+// Inside your Map Navigation Modal / Layer component wrapper:
+export const LocationNavigationModal = ({ isOpen, routeData }) => {
+  const [isSearchingRoute, setIsSearchingRoute] = useState(false);
+  const mapInstanceRef = useRef<any>(null);
+  
+  // CRITICAL FIX 2: Guard mechanism to block concurrent duplicated queries
+  const fetchLockRef = useRef(false);
+
+  // Deconstruct coordinate primitives to secure a stable dependency array
+  const originLat = routeData?.origin?.lat;
+  const originLng = routeData?.origin?.lng;
+  const destLat = routeData?.destination?.lat;
+  const destLng = routeData?.destination?.lng;
+
+  useEffect(() => {
+    if (!isOpen || !originLat || !originLng || !destLat || !destLng) return;
+    
+    // If an operation is already locked and active, bail out immediately to prevent loops
+    if (fetchLockRef.current) return;
+
+    const calculateOptimalRoute = async () => {
+      try {
+        // 1. Activate loading feedback banner
+        setIsSearchingRoute(true);
+        fetchLockRef.current = true; // Engage execution lock
+
+        console.log("Fetching route coordinates exactly once...");
+        
+        // --- YOUR MAP COMPONENT ROUTING LOGIC START ---
+        // Example: const response = await directionsService.route({...});
+        // await mapInstanceRef.current.drawPolyline(response);
+        // --- YOUR MAP COMPONENT ROUTING LOGIC END ---
+
+      } catch (error) {
+        console.error("Failed to compile route optimization maps:", error);
+      } finally {
+        // 2. Safe, definitive termination of the tracking states
+        setIsSearchingRoute(false);
+        fetchLockRef.current = false; // Disengage execution lock
+      }
+    };
+
+    calculateOptimalRoute();
+
+    // Cleanup phase: Reset execution parameters when inputs dismantle or modal closes
+    return () => {
+      fetchLockRef.current = false;
+      setIsSearchingRoute(false);
+    };
+    
+    /* CRITICAL FIX 1: Explicitly tracking primitives only. 
+       Do NOT pass full 'routeData', 'mapInstanceRef' or object literals here!
+    */
+  }, [isOpen, originLat, originLng, destLat, destLng]);
+
+  return (
+    <div className="relative w-full h-full">
+      {/* Map Content Target Canvas */}
+      <div id="navigation-viewport-map-canvas" className="w-full h-full" />
+
+      {/* RENDER CONTROLLER: Only mount the label if routing calculations are actively processing */}
+      {isSearchingRoute && (
+        <div className="absolute top-16 left-4 z-30 bg-white/95 dark:bg-slate-900/95 border border-slate-200 dark:border-slate-800 px-3 py-1.5 rounded-full shadow-lg flex items-center gap-2 animate-pulse">
+          {/* Circular Loading Spinner Element */}
+          <div className="w-3.5 h-3.5 border-2 border-blue-500 border-t-transparent rounded-full animate-spin" />
+          <span className="text-[11px] font-bold text-slate-700 dark:text-slate-200 uppercase tracking-wider">
+            ĐANG TÌM ĐƯỜNG TỐI ƯU...
+          </span>
+        </div>
+      )}
+    </div>
+  );
+};
+
+## 4. Verification & Quality Acceptance Criteria
+[ ] Single Instance Trigger: Check console telemetry outputs. When the map modal mounts, the route compilation routine must print its trace log exactly once.
+
+[ ] Flicker Nullification: The "ĐANG TÌM ĐƯỜNG TỐI ƯU..." badge must display smoothly with an animation pulse. It must not shake, blink, flash, or rapid-cycle on and off.
+
+[ ] Deterministic Hiding: As soon as the blue route line draws completely across the map terrain grid layout, the loading badge must cleanly unmount and disappear from view without reappearing unless a new destination node button is clicked.

-# To AI Agent: Refactor Itinerary Timeline into an Exclusive File Tree Directory System (Single Expansion Mode)
-
-## 1. Context & Architectural Analogy
-We are refactoring the `ItineraryTimeline` component on the mobile view (`yotrip.labz.io.vn`) using a **File Tree Directory System** analogy:
-- **Parent Folders ("Thư mục mẹ"):** Represented by the Stages ("Chặng 1", "Chặng 2"...).
-- **Child Nodes ("Thư mục con"):** Represented by the Locations/Destinations inside that stage (`Trần Cao Vân`, `Đồng Khởi`...).
-
-### CRITICAL LOGIC CONSTRAINT (Exclusive Accordion):
-- When a Parent Folder (Stage) is **collapsed**, all of its Child Nodes (Locations) must immediately hide cleanly inside it.
-- **Single Expansion Rule:** The system must enforce an **exclusive single-expansion mode**. On the entire timeline screen, **MAXIMUM ONE** Parent Folder can be expanded at any given time. 
-- Opening/Expanding a new Stage folder must **automatically collapse** whichever Stage folder was previously open.
-
----
-
-## 2. State Management Specification (For Script/Logic Implementation)
-
-To enforce the "Maximum 1 Expanded Folder" rule, do NOT use isolated individual boolean flags for each stage. Instead, implement a centralized single-active-state variable:
-
-```javascript
-// Example React State Hook Blueprint:
-// Track the ID or index of the single active expanded stage folder. 
-// If null, all stages are collapsed.
-const [expandedStageId, setExpandedStageId] = useState(initialStageId);
-
-const handleStageToggle = (stageId) => {
-  // If clicking the already open folder, close it. Otherwise, open the new one and shut the rest.
-  setExpandedStageId(prevId => prevId === stageId ? null : stageId);
-};
-
-## 3. Component DOM Tree & CSS Blueprint
-### A. Component Layout Structure

-## 4. Acceptance Criteria for AI Agent Verification
-[ ] Mutually Exclusive Test: Clicking an inactive Stage header while another stage is open must trigger a simultaneous transition: the old stage collapses back into a tight header row, and the clicked stage expands its location cards.
-
-[ ] Zero-Gap Validation: All collapsed folder components must sit completely flush against the top tab block and one another, eliminating all gray margin bleeding.
-
-[ ] Under-Clip Containment: When scrolling a long open folder, the list items must slide behind their sticky active parent folder row and disappear without visual overlapping artifacts.

+# To AI Agent: Implement Clickable Google Maps Hyperlinks in PDF Export Table
+
+## 1. Context & Feature Objective
+We are upgrading the PDF export functionality within the Yotrip Travel Planner application. Currently, the PDF generates a static table containing location names, addresses, and coordinates.
+**Objective:** Automatically turn every location row inside the PDF table into an interactive, clickable hyperlink. When a user clicks on the location cell in the generated PDF document, it must immediately open a browser tab navigating directly to that exact location on Google Maps.
+
+---
+
+## 2. Technical Architecture & Data Strategy
+
+Because `jspdf-autotable` draws text onto a canvas layout, raw HTML tags like `<a>` will fail. We must implement a two-step rendering lifecycle:
+1. **Extraction & Styling State:** During the data loop, verify coordinates or address data. Generate a standard universal Google Maps search URL, save it into a coordinate-tracking index object, and transform the raw text cell into a styled cell object (Yale Blue text `#28536b` to mimic an online link).
+2. **Link Injection Layer:** Utilize the `didDrawCell` hook callback inside the `doc.autoTable` configuration to position a native invisible link window (`doc.link()`) precisely over the drawn dimensions of that specific location cell.
+
+---
+
+## 3. Code Refactoring Specification
+
+### Step 1: Update Data Preparation Loop
+Locate the loop processing `currentTour.legs` inside your PDF generation code block. Initialize a temporary lookup map array named `pdfMapLinks` and refactor the item distribution logic as follows:
+
+```typescript
+// Initialize an index mapping registry for hyperlinks before the loop execution
+const pdfMapLinks: { [key: number]: string } = {};
+
+if (currentTour?.legs && currentTour.legs.length > 0) {
+  currentTour.legs.forEach((leg: any, legIdx: number) => {
+    const legName = leg.note || `Chặng ${legIdx + 1}`;
+    const legLocations = (leg.locations || []).filter((loc: any) =>
+      loc && (loc.plannedStart || loc.plannedEnd || loc.name)
+    );
+
+    const startRow = globalRowIndex;
+
+    if (legLocations.length > 0) {
+      legRowRanges[leg.id] = { start: startRow, count: legLocations.length };
+
+      legLocations.forEach((loc: any, locIdx: number) => {
+        const isStartPoint = loc.plannedStart && new Date(loc.plannedStart).getTime() === 0;
+        const timeSource = isStartPoint ? loc.plannedEnd : loc.plannedStart;
+        const timeStr = timeSource ? formatDateTime(timeSource) : '';
+
+        const locName = loc.name || '';
+        const addressStr = loc.address || '';
+        const coordStr = loc.latitude && loc.longitude
+          ? `\n${loc.latitude}, ${loc.longitude}`
+          : '';
+        const locationText = [locName, addressStr, coordStr].filter(Boolean).join('\n');
+        const noteText = loc.note || '';
+
+        // 1. Generate standard universal Google Maps URL query pattern
+        let mapUrl = '';
+        if (loc.latitude && loc.longitude) {
+          // Absolute Precision using GPS coordinates
+          mapUrl = `https://www.google.com/maps/search/?api=1&query=${loc.latitude},${loc.longitude}`;
+        } else if (addressStr || locName) {
+          // Text-search query fallback if GPS coordinates are missing
+          mapUrl = `https://www.google.com/maps/search/?api=1&query=${encodeURIComponent(addressStr || locName)}`;
+        }
+
+        // 2. Register current row array position to map lookup index
+        const currentRowPosition = tableRows.length;
+        if (mapUrl) {
+          pdfMapLinks[currentRowPosition] = mapUrl;
+        }
+
+        // 3. Convert raw string into custom styled autoTable Cell configuration object
+        const locationCellObj = {
+          content: locationText,
+          // Apply custom link colors matching theme style #28536b (Yale Blue)
+          styles: mapUrl ? { textColor: [40, 83, 107], fontStyle: 'bold' as const } : {}
+        };
+
+        tableRows.push([
+          stt++,
+          timeStr,
+          locIdx === 0 ? legName : '',
+          locationCellObj, // Injected as cell structure object
+          noteText
+        ]);
+        globalRowIndex++;
+      });
+    } else {
+      legRowRanges[leg.id] = { start: startRow, count: 1 };
+      tableRows.push([
+        stt++,
+        '',
+        legName,
+        'Chưa có địa điểm trong chặng này',
+        ''
+      ]);
+      globalRowIndex++;
+    }
+  });
+}
+
+### Step 2: Inject Coordinate-Based Overlay inside doc.autoTable
+Locate the core configuration module block where doc.autoTable({}) is invoked. Inject the didDrawCell event engine to deploy the link bounds:
+
+doc.autoTable({
+  head: [['STT', 'Thời gian', 'Chặng', 'Địa điểm', 'Ghi chú']],
+  body: tableRows,
+  theme: 'grid',
+  
+  // HOOK HANDLER: Overlays active coordinate zones on top of native cells after writing
+  didDrawCell: (data: any) => {
+    // Target explicitly: body section only + column index 3 (Location Column)
+    if (data.section === 'body' && data.column.index === 3) {
+      const activeRowIndex = data.row.index;
+      const targetMapUrl = pdfMapLinks[activeRowIndex];
+      
+      if (targetMapUrl) {
+        // Build active link container utilizing jsPDF coordinates framework
+        data.doc.link(
+          data.cell.x, 
+          data.cell.y, 
+          data.cell.width, 
+          data.cell.height, 
+          { url: targetMapUrl }
+        );
+      }
+    }
+  },
+  styles: { font: 'Roboto' } // Retain existing styling structure
+});
+
+## 4. Quality Control & Acceptance Criteria
+[ ] Visual Differentiation: Location text cells containing map URLs must render cleanly in bold dark-blue ([40, 83, 107]) while empty state texts stay muted.
+
+[ ] Coordinate Precision: Clicking a location card possessing explicit coordinates (latitude, longitude) must directly map to those absolute markers instead of doing an inaccurate keyword address query.
+
+[ ] Boundary Accuracy: The click targets must fit perfectly inside the grid cell borders. Clicking near the edges of column 3 must register properly, while clicking column 2 (Leg name) or column 4 (Notes) must remain non-reactive.

+# To AI Agent: Audit Location Lock Bug and Refactor GPS Tracking into a Toggle Stateful Button
+
+## 1. Context & Problem Statement
+Currently, in our travel planner application map engine (on pages like `TourNavigationPage.tsx`, `LocationNavigationModal.tsx`, or map utilities), the viewport is continuously forced to lock onto the user's live GPS position. This architecture severely damages mobile UX because:
+1. It prevents users from manually dragging, panning, or scouting other areas of the map terrain.
+2. There is no control interface to temporarily mute or disable live GPS tracking.
+
+**Objective:** - Run a global audit across the entire codebase to locate functions driving this forced-center trap (e.g., custom hooks, `requestGpsPosition`, native geolocation callbacks, or reactive map state updates).
+- Refactor the logic so that live tracking is bound strictly to an independent toggle state button. The map must **ONLY** lock/re-center on the user's coordinates when this tracking toggle button is actively switched **ON**.
+
+---
+
+## 2. Phase 1: Codebase Audit Plan (Where to Search)
+
+Scan the entire project repository (specifically `/frontend/src`) using code search patterns to intercept the lock mechanism. Target the following files and keywords:
+
+### Key Target Files to Inspect:
+- `frontend/src/pages/TourNavigationPage.tsx`
+- `frontend/src/components/LocationNavigationModal.tsx`
+- Any custom hooks or contexts handling geography, such as `useGeolocation.ts`, `useMap.ts`, or generic map setup wrappers.
+
+### Regex & Keyword Global Search Queries:
+- Search for native background watchers: `navigator.geolocation.watchPosition` or `navigator.geolocation.getCurrentPosition`
+- Search for custom map-centering loops: `requestGpsPosition`, `followUser`, `centerToUser`
+- Search for viewport mutation commands specific to our active map engine stack:
+  - **Leaflet:** `.setView(`, `.panTo(`, `center={`
+  - **Mapbox GL JS:** `.flyTo(`, `.easeTo(`, `.jumpTo(`
+
+---
+
+## 3. Phase 2: Technical Refactoring Blueprint
+
+Once the tracking logic code blocks are isolated from Phase 1, implement the structural state safety rails below:
+
+### Step 1: Initialize the Tracking State Guard
+Introduce a state hook controller (`isTrackingLocation`) to manage whether the view should actively mirror device coordinates:
+
+```typescript
+// Add inside the map controller/page container component
+const [isTrackingLocation, setIsTrackingLocation] = useState(false);
+const watchIdRef = useRef<number | null>(null);
+
+### Step 2: Encapsulate the Geolocation Watcher Handler
+Wrap your positioning tracking engine loop inside a conditional check governed directly by the state guard. Ensure that if the tracking state is disabled, the background watcher cleanly unmounts:
+
+useEffect(() => {
+  if (isTrackingLocation) {
+    if (navigator.geolocation) {
+      console.log("GPS Location Tracking engaged. Syncing viewport to center...");
+      
+      watchIdRef.current = navigator.geolocation.watchPosition(
+        (position) => {
+          const { latitude, longitude, heading } = position.coords;
+          
+          if (mapRef.current) {
+            // ✅ CORRECTION: Viewport ONLY repositions center when tracking button is active
+            mapRef.current.easeTo({
+              center: [longitude, latitude],
+              zoom: 16, // Lock to comfortable navigation zoom level
+              duration: 600
+            });
+          }
+        },
+        (error) => console.error("GPS stream tracking lost:", error),
+        { enableHighAccuracy: true }
+      );
+    }
+  } else {
+    // Clean up tracking process instantly when toggled OFF
+    if (watchIdRef.current !== null) {
+      navigator.geolocation.clearWatch(watchIdRef.current);
+      watchIdRef.current = null;
+      console.log("GPS Location Tracking disabled. Map control released to user.");
+    }
+  }
+
+  return () => {
+    if (watchIdRef.current !== null) navigator.geolocation.clearWatch(watchIdRef.current);
+  };
+}, [isTrackingLocation]);
+
+### Step 3: Implement Gesture Detection (UX Safety Rail)
+If the user manually drags the screen while tracking is active, the tracking state must automatically toggle OFF so the viewport doesn't fight against the user's finger movements:
+
+useEffect(() => {
+  if (!mapRef.current) return;
+  const map = mapRef.current;
+
+  const breakTrackingOnGesture = () => {
+    if (isTrackingLocation) {
+      console.log("User touch map interaction detected. Disengaging auto-center lock.");
+      setIsTrackingLocation(false); // Automatically drop tracking flag on map pan/zoom
+    }
+  };
+
+  map.on('dragstart', breakTrackingOnGesture);
+  map.on('zoomstart', breakTrackingOnGesture);
+  map.on('movestart', breakTrackingOnGesture);
+
+  return () => {
+    map.off('dragstart', breakTrackingOnGesture);
+    map.off('zoomstart', breakTrackingOnGesture);
+    map.off('movestart', breakTrackingOnGesture);
+  };
+}, [isTrackingLocation]);
+
+### Step 4: Render the UI Toggle Button UI Component
+Deploy a new independent floating button on top of the map canvas workspace (placed at bottom-24 right-6, just right above your custom Compass button layout):
+
+{/* FLOATING LIVE GPS TRACKING CENTER LOCK BUTTON */}
+<button
+  onClick={() => setIsTrackingLocation(!isTrackingLocation)}
+  className={`absolute bottom-24 right-6 z-40 w-14 h-14 rounded-full border-2 flex items-center justify-center shadow-2xl transition-all active:scale-95 ${
+    isTrackingLocation 
+      ? 'bg-green-600 border-green-400 text-white animate-pulse' 
+      : 'bg-white dark:bg-slate-900 border-slate-200 dark:border-slate-700 text-slate-600 dark:text-green-500'
+  }`}
+  title={isTrackingLocation ? "Tắt tự động định tâm vị trí" : "Bật tự động định tâm theo vị trí của bạn"}
+>
+  {/* Replace Crosshair icon element with your active layout icon package asset */}
+  <svg xmlns="[http://www.w3.org/2000/svg](http://www.w3.org/2000/svg)" className="w-7 h-7" fill="none" viewBox="0 0 24 24" stroke="currentColor" strokeWidth={2}>
+    <path strokeLinecap="round" strokeLinejoin="round" d="M12 8v4m0 4h.01M21 12a9 9 0 11-18 0 9 9 0 0118 0z" />
+  </svg>
+</button>
+
+## 4. Verification & Quality Acceptance Criteria
+
+[ ] Code Erasure Verification: Confirm that old continuous loops or uncontrolled recursive .setView/.easeTo methods triggered instantly on map load are fully removed or properly contained inside the state block.
+
+[ ] Default State Freedom: Upon opening the map page path, tracking must default to OFF. Users must be able to drag the map anywhere in the world without the screen snapped or yanked back to their physical house position.
+
+[ ] Toggle Activation Centering: Pressing the new GPS tracking button must instantly engage the animation, center the map view directly on top of the user blue dot icon, and follow them smoothly if they move.
+
+[ ] Manual Override Interception: Turn tracking ON. Drag the map manually with a finger gesture. Verify that the tracking button instantly changes style states back to deactivated and tracking shuts down cleanly.
