+# GiftedDialog Complete Documentation
+
+## Overview
+
+The GiftedDialog system is a sophisticated multi-step dialog for recording gifts between people and projects in the TimeSafari application. It consists of a main orchestrating component and 9 specialized child components that handle different aspects of the gift recording workflow.
+
+## Key Features
+
+- **Two-Step Workflow**: Entity selection → Gift details
+- **Multi-Entity Support**: People, projects, and special entities  
+- **Conflict Detection**: Prevents invalid gift combinations
+- **Responsive Design**: Works across all device sizes
+- **Accessibility**: Full keyboard navigation and screen reader support
+- **Validation**: Comprehensive form validation and error handling
+- **Flexible Integration**: Can be embedded in any view with different contexts
+
+## Component Architecture
+
+### Main Component
+- **GiftedDialog.vue** - Main orchestrating component that manages dialog state, step navigation, and API integration
+
+### Step Components  
+- **EntitySelectionStep.vue** - Step 1 controller with dynamic labeling and context awareness
+- **GiftDetailsStep.vue** - Step 2 controller with form validation and entity summaries
+
+### Layout Components
+- **EntityGrid.vue** - Unified entity grid layout with responsive design
+- **EntitySummaryButton.vue** - Selected entity display with edit capability
+
+### Display Components
+- **PersonCard.vue** - Individual person display with avatar and selection states
+- **ProjectCard.vue** - Individual project display with icons and issuer information
+- **SpecialEntityCard.vue** - Special entities (You, Unnamed) with conflict detection
+- **ShowAllCard.vue** - Navigation component with router integration
+
+### Input Components
+- **AmountInput.vue** - Numeric input with increment/decrement controls and validation
+
+## Data Flow
+
+### Step 1: Entity Selection
+1. User opens dialog → GiftedDialog renders EntitySelectionStep
+2. EntitySelectionStep renders EntityGrid with entities and configuration
+3. EntityGrid renders PersonCard/ProjectCard/SpecialEntityCard components
+4. User clicks entity → Card emits to Grid → Grid emits to Step → Step emits to Dialog
+5. GiftedDialog updates state and advances to step 2
+
+### Step 2: Gift Details  
+1. GiftedDialog renders GiftDetailsStep with selected entities
+2. GiftDetailsStep renders EntitySummaryButton and AmountInput components
+3. User fills form and clicks submit → Step emits to Dialog
+4. GiftedDialog processes submission via API and handles success/error
+
+## Key Props and Configuration
+
+### GiftedDialog Props
+```typescript
+interface GiftedDialogProps {
+  fromProjectId?: string;      // Project ID when project is giver
+  toProjectId?: string;        // Project ID when project is recipient  
+  showProjects?: boolean;      // Whether to show projects
+  isFromProjectView?: boolean; // Context flag for project views
+}
+```
+
+### Opening the Dialog
+```typescript
+// Basic usage
+giftedDialog.open();
+
+// With pre-selected entities and context
+giftedDialog.open(
+  giverEntity,      // Pre-selected giver
+  receiverEntity,   // Pre-selected receiver  
+  offerId,          // Offer context
+  customTitle,      // Custom dialog title
+  prompt,           // Custom input prompt
+  successCallback   // Success handler
+);
+```
+
+## Integration Patterns
+
+### Basic Integration
+```vue
+<template>
+  <div>
+    <button @click="openGiftDialog">Record Gift</button>
+    <GiftedDialog ref="giftedDialog" />
+  </div>
+</template>
+
+<script lang="ts">
+export default class Example extends Vue {
+  openGiftDialog() {
+    const dialog = this.$refs.giftedDialog as GiftedDialog;
+    dialog.open();
+  }
+}
+</script>
+```
+
+### Project Context Integration
+```typescript
+// Gift from project
+dialog.open(
+  projectEntity,    // Project as giver
+  undefined,        // User selects receiver
+  undefined,        // No offer
+  "Gift from Project",
+  "What did this project provide?"
+);
+
+// Gift to project  
+dialog.open(
+  undefined,        // User selects giver
+  projectEntity,    // Project as receiver
+  undefined,        // No offer
+  "Gift to Project", 
+  "What was contributed to this project?"
+);
+```
+
+## State Management
+
+The dialog manages internal state through a reactive system:
+
+- **Step Navigation**: Controls progression from entity selection to gift details
+- **Entity Selection**: Tracks selected giver and receiver entities
+- **Conflict Detection**: Prevents selecting same person for both roles
+- **Form Validation**: Ensures required fields are completed
+- **API Integration**: Handles gift submission and response processing
+
+## Conflict Detection Logic
+
+```typescript
+function wouldCreateConflict(selectedDid: string): boolean {
+  // Only applies to person-to-person gifts
+  if (giverEntityType !== "person" || recipientEntityType !== "person") {
+    return false;
+  }
+  
+  // Check if selecting same person for both roles
+  if (stepType === "giver") {
+    return receiver?.did === selectedDid;
+  } else if (stepType === "recipient") {
+    return giver?.did === selectedDid;
+  }
+  
+  return false;
+}
+```
+
+## AmountInput Component Fix
+
+The AmountInput component was recently fixed to resolve an issue where increment/decrement buttons weren't updating the displayed value:
+
+### Problem
+- Input field used `:value="displayValue"` (one-way binding)
+- Programmatic updates to `displayValue` weren't reflected in DOM
+
+### Solution  
+- Changed to `v-model="displayValue"` (two-way binding)
+- Now properly synchronizes programmatic and user input changes
+
+### Usage
+```vue
+<AmountInput
+  :value="amount"
+  :min="0"
+  :max="1000"
+  :step="1"
+  @update:value="handleAmountChange"
+/>
+```
+
+## Testing Strategy
+
+### Unit Testing
+- Individual component behavior
+- Props validation
+- Event emission
+- Computed property calculations
+
+### Integration Testing  
+- Multi-component workflows
+- State management
+- API integration
+- Error handling
+
+### End-to-End Testing
+- Complete user workflows
+- Cross-browser compatibility
+- Accessibility compliance
+- Performance validation
+
+## Security Considerations
+
+- **Input Validation**: All user inputs are sanitized and validated
+- **DID Privacy**: User identifiers only shared with authorized contacts  
+- **API Security**: Requests are cryptographically signed
+- **XSS Prevention**: Template sanitization and CSP headers
+
+## Performance Optimizations
+
+- **Lazy Loading**: Components loaded only when needed
+- **Virtual Scrolling**: For large entity lists
+- **Debounced Input**: Prevents excessive API calls
+- **Computed Properties**: Efficient reactive calculations
+- **Memory Management**: Proper cleanup on component destruction
+
+## Accessibility Features
+
+- **Keyboard Navigation**: Full tab order and keyboard shortcuts
+- **Screen Reader Support**: ARIA labels and semantic HTML
+- **Focus Management**: Proper focus handling on open/close
+- **High Contrast**: Supports high contrast themes
+- **Responsive Design**: Works on all screen sizes
