Architecture Design Progress:
- [ ] Step 1: Understand requirements and constraints
- [ ] Step 2: Assess project size and team capabilities
- [ ] Step 3: Select architecture pattern
- [ ] Step 4: Define directory structure
- [ ] Step 5: Document trade-offs and decision
- [ ] Step 6: Validate against decision framework

## Decision: [What we're deciding]

### Context
[Why this decision is needed now]

### Options Considered
1. Option A: [Description]
2. Option B: [Description]

### Trade-offs
| Criteria | Option A | Option B |
|----------|----------|----------|
| Complexity | Low | High |
| Scalability | Medium | High |
| Team familiarity | High | Low |

### Decision
We chose [Option] because [reasoning].

### Consequences
- [What this enables]
- [What this constrains]

Architecture Validation:
- [ ] Matches project size and complexity
- [ ] Aligns with team skills and experience
- [ ] Supports current requirements
- [ ] Allows for anticipated growth
- [ ] Dependencies flow inward (core has no external deps)
- [ ] Clear boundaries between modules/layers
- [ ] Testing strategy is feasible
- [ ] Trade-offs are documented
