## Product Solution Description
[Short description. Brief component interaction diagram. Written as if from scratch — no "updated" markers.]

## Architecture

[Architecture solution that meets restrictions and acceptance criteria.]

### Component: [Component Name]

| Solution | Tools | Advantages | Limitations | Requirements | Security | Performance | Fit |
|----------|-------|-----------|-------------|-------------|----------|------------|-----|
| [Option 1] | [lib/platform] | [pros] | [cons] | [intrinsic requirements] | [security] | [perf] | [Selected / Rejected / Experimental only / Needs user decision — cite exact-fit evidence and disqualifiers] |
| [Option 2] | [lib/platform] | [pros] | [cons] | [intrinsic requirements] | [security] | [perf] | [Selected / Rejected / Experimental only / Needs user decision — cite exact-fit evidence and disqualifiers] |

**Exact-fit evidence**:
- Project constraints checked: [inputs/outputs, operating context, lifecycle, NFRs, acceptance criteria]
- Evidence: [Fact # / Source #]
- Disqualifiers: [none or list]

[Repeat per component]

## Testing Strategy

### Integration / Functional Tests
- [Test 1]
- [Test 2]

### Non-Functional Tests
- [Performance test 1]
- [Security test 1]
