# Sprint 0: Foundation

**Status**: ✅ Complete
**Duration**: Pre-Sprint 1
**Epic**: N/A (Initial Setup)

## Goal
Establish project structure, specifications, and web UI shell to enable Sprint 1 development.

## User Story
As a developer, I want the foundational project structure in place so that I can begin building core features with a clear architecture and basic UI framework.

## Implementation Tasks

### Core Deliverables (P0)
- [x] **Technical Specification**: CODEFRAME_SPEC.md created
- [x] **Python Package Structure**: src/ directory with package layout
- [x] **FastAPI Status Server**: Basic server with mock data endpoints
- [x] **Next.js Web Dashboard**: Dashboard shell with static UI
- [x] **Git Repository**: Initialized and pushed to GitHub

### Infrastructure (P0)
- [x] **Database Schema**: SQLite schema for projects, agents, tasks, memory
- [x] **API Contracts**: REST endpoints defined for status server
- [x] **WebSocket Protocol**: Message types specified for real-time updates

## Definition of Done
- [x] Technical specification documents project architecture
- [x] Dashboard renders with mock data (looks real)
- [x] Status Server returns mock project/agent data
- [x] Python package structure follows best practices
- [x] Git repository created and initial commit pushed

## Key Commits
- Initial project structure
- Technical specification
- Dashboard UI shell
- Status server with mock endpoints

## Metrics
- **Tests**: 0 (pre-TDD phase)
- **Coverage**: N/A
- **Deliverables**: 4/4 complete

## Sprint Retrospective

### What Went Well
- Clear technical specification provided excellent foundation
- Next.js + FastAPI architecture proved solid
- Mock data approach allowed rapid UI prototyping
- Git repository structure clean from day one

### What Could Improve
- Could have defined test strategy earlier
- Database schema required refinement in Sprint 1
- WebSocket protocol evolved during implementation

### Key Learnings
- Starting with comprehensive specs saves time later
- Mock data valuable for UI development
- Separation of concerns (UI, API, DB) essential for parallel work
- Early architecture decisions (FastAPI, Next.js, SQLite) validated through implementation

## References
- **Specification**: CODEFRAME_SPEC.md
- **Architecture**: Multi-tier (Web UI, API Server, Database)
- **Technologies**: Python 3.11+, FastAPI, Next.js 13+, SQLite
