## Functional Requirements

<!-- List functional requirements with FR-NNN IDs -->

| ID | Priority | Requirement | Status | Test Coverage |
|----|----------|-------------|--------|---------------|
| FR-001 | P1 | System MUST [capability] | 🔴 Draft | ❌ |
| FR-002 | P1 | System MUST [capability] | 🔴 Draft | ❌ |
| FR-003 | P2 | Users MUST be able to [interaction] | 🔴 Draft | ❌ |

## Non-Functional Requirements

<!-- Quality attributes: performance, security, reliability -->

| ID | Category | Requirement | Metric |
|----|----------|-------------|--------|
| NFR-001 | Performance | Response time < 200ms p95 | Measured via [tool] |
| NFR-002 | Security | All endpoints require authentication | Validated by guard |
| NFR-003 | Reliability | 99.9% uptime SLA | Monitored via [tool] |

## Success Criteria

<!-- Measurable outcomes — aligned with spec-kit SC-NNN format -->

| ID | Criteria | Measurement | Target |
|----|----------|-------------|--------|
| SC-001 | [Measurable user outcome] | [How measured] | [Target value] |
| SC-002 | [Performance metric] | [How measured] | [Target value] |

## User Scenarios

<!-- Spec-kit aligned: Given/When/Then acceptance scenarios -->

### User Story 1 - [Title] (Priority: P1)

[Description of user journey]

**Acceptance Scenarios**:
1. **Given** [initial state], **When** [action], **Then** [expected outcome]
2. **Given** [initial state], **When** [action], **Then** [expected outcome]

## Traceability Matrix

<!-- Maps requirements → code → tests -->

| Requirement | Source File | Test File | Status |
|-------------|------------|-----------|--------|
| FR-001 | `src/[file]` | `tests/[file]` | ❌ |
