+# Design: project-completion
+
+## Overview
+
+{2-3 paragraph summary of the technical approach, including key architectural decisions and rationale}
+
+## Architecture
+
+### System Context
+
+{How this fits into the broader system architecture}
+
+**Key Components:**
+
+- **{Component 1}:** {Purpose and responsibilities}
+- **{Component 2}:** {Purpose and responsibilities}
+
+### Component Diagram
+
+```
+{ASCII diagram or description of component relationships}
+```
+
+### Data Flow
+
+{Description of how data moves through the system}
+
+```
+{Sequence diagram or step-by-step flow}
+```
+
+## Component Design
+
+### {Component Name}
+
+**Purpose:** {What this component does}
+
+**Responsibilities:**
+
+- {Responsibility 1}
+- {Responsibility 2}
+
+**Interfaces:**
+
+```typescript
+// Key interfaces, classes, or function signatures
+```
+
+**Dependencies:**
+
+- {Internal dependency 1}
+- {External dependency 1}
+
+**Design Decisions:**
+
+- {Decision 1 and rationale}
+
+## Data Models
+
+### {Model Name}
+
+**Purpose:** {What this represents}
+
+**Schema:**
+
+```typescript
+interface ModelName {
+  // Field definitions with types
+}
+```
+
+**Validation Rules:**
+
+- {Rule 1}
+- {Rule 2}
+
+**Storage:**
+
+- **Location:** {Database, file system, memory}
+- **Persistence:** {How/when data is persisted}
+
+## API Design
+
+### {Endpoint/Interface Name}
+
+**Method:** GET / POST / PUT / DELETE
+**Path:** `/api/v1/{resource}`
+
+**Request:**
+
+```typescript
+interface Request {
+  // Request schema
+}
+```
+
+**Response:**
+
+```typescript
+interface Response {
+  // Response schema
+}
+```
+
+**Error Handling:**
+
+- {Error code}: {Description}
+
+**Authorization:** {Auth requirements}
+
+## Security Considerations
+
+### Authentication
+
+{How users/services authenticate}
+
+### Authorization
+
+{How permissions are enforced}
+
+### Data Protection
+
+- **Encryption:** {At rest, in transit}
+- **PII Handling:** {How sensitive data is protected}
+- **Input Validation:** {Where and how inputs are validated}
+
+### Threat Mitigation
+
+- **{Threat 1}:** {Mitigation strategy}
+- **{Threat 2}:** {Mitigation strategy}
+
+## Performance Considerations
+
+### Scalability
+
+{How the design scales with load}
+
+### Caching
+
+- **Layer:** {Where caching occurs}
+- **Strategy:** {Cache invalidation approach}
+- **TTL:** {Time-to-live values}
+
+### Database Optimization
+
+- **Indexes:** {Key indexes to create}
+- **Query Optimization:** {Query patterns to optimize}
+
+### Resource Limits
+
+- **Memory:** {Expected usage}
+- **CPU:** {Expected usage}
+- **Network:** {Expected bandwidth}
+
+## Error Handling
+
+### Error Categories
+
+- **User Errors:** {How handled}
+- **System Errors:** {How handled}
+- **External Service Errors:** {How handled}
+
+### Retry Logic
+
+{When and how retries are performed}
+
+### Logging
+
+- **Info:** {What to log at info level}
+- **Warn:** {What to log at warn level}
+- **Error:** {What to log at error level}
+
+## Testing Strategy
+
+### Requirement-to-Test Mapping
+
+{Maps spec requirements to test levels and key scenarios — ensures every requirement has a verification plan}
+
+| ID   | Verification                       | Key Scenarios              |
+| ---- | ---------------------------------- | -------------------------- |
+| FR1  | {unit/integration/e2e/manual/perf} | {Scenario 1}, {Scenario 2} |
+| FR2  | {unit/integration/e2e/manual/perf} | {Scenario 1}               |
+| NFR1 | {unit/integration/e2e/manual/perf} | {Scenario 1}               |
+
+**Notes:**
+
+- Pull ID from spec.md Requirement Index
+- Copy the **method** (left side of `method: pointer`) into Verification
+- Use the **pointer** (right side) to seed Key Scenarios, then expand based on design
+- Multiple test levels are valid (e.g., "unit + integration")
+
+### Unit Tests
+
+- **Scope:** {What gets unit tested}
+- **Coverage Target:** {N}%
+- **Key Test Cases:**
+  - {Test case 1}
+  - {Test case 2}
+
+### Integration Tests
+
+- **Scope:** {What gets integration tested}
+- **Test Environment:** {How environment is set up}
+- **Key Test Cases:**
+  - {Test case 1}
+  - {Test case 2}
+
+### End-to-End Tests
+
+- **Scope:** {What gets E2E tested}
+- **Test Scenarios:**
+  - {Scenario 1}
+  - {Scenario 2}
+
