<current_state>
Phase 1 (Foundation) is code-complete on dev machine. All Go code written, Dockerfile created, Docker Compose configured. Docker runtime verification deferred to Raspberry Pi deployment due to corporate proxy blocking Docker Hub registry access on dev machine.

Project state: Ready for handoff to Raspberry Pi for Docker runtime verification and Phase 2 development.
</current_state>

## Phase 1: Foundation - Complete on Dev Machine

### Plan 01-01: Go project structure and multi-stage Dockerfile
- ✓ Go module initialized (github.com/acty/pirate-station)
- ✓ HTTP server on port 32768 with two endpoints:
  - `/` - Returns "Pirate Station API"
  - `/health` - JSON response, healthy when /data mounted
- ✓ Health check handler in internal/health package
- ✓ Multi-stage Dockerfile (golang:1.25-bookworm → debian:bookworm-slim)
- ✓ Static binary compilation with CGO_ENABLED=0
- ✓ Non-root container user (appuser, UID 10001)
- ✓ .dockerignore created
- ✓ Cross-compilation verified (4.4MB amd64, 4.2MB arm64 binaries)
- Commit: 2691ded, 38edbf6, 257edf5

### Plan 01-02: Docker Compose dev environment
- ✓ docker-compose.yml with builder stage target for dev
- ✓ Bind mount for live editing
- ✓ Named volume for persistent data
- ✓ Air hot reload configuration (.air.toml)
- ✓ Local Go verification (server runs, endpoints respond)
- ✓ YAML validation passed
- Commit: 6cbf414, c09f4d7

### Phase Completion
- ✓ VERIFICATION.md created (7/7 must-haves verified, 4 deferred)
- ✓ ROADMAP.md updated (Phase 1 marked complete)
- ✓ REQUIREMENTS.md updated (INFRA-01, INFRA-02 marked complete)
- ✓ STATE.md updated
- ✓ HANDOFF.md created with Pi deployment instructions
- Commit: c8cd06b, e859c48

## Phase 1: Docker Runtime Verification (Deferred to Pi)

Must verify on Raspberry Pi when Docker Hub is accessible:

1. **Docker image build** - `docker build -f docker/Dockerfile -t pirate-station:latest .`
2. **Image size verification** - Should be under 150MB (estimated 80MB)
3. **Container isolation test** - Verify container cannot access host filesystem outside /data
4. **Health endpoint in container** - Test both with and without /data volume
5. **Docker Compose startup** - `docker compose up --build` should work
6. **Hot reload in container** - Air should detect changes and rebuild

See `HANDOFF.md` for complete verification checklist.

## Phase 2: CLI Tool (Not Started)

After Phase 1 verification on Pi, proceed to Phase 2:

1. Run `/gsd:discuss-phase 2` to gather context about:
   - User storage format (SQLite, JSON, etc.)
   - Password hashing algorithm
   - CLI tool structure
   - Database location in /data volume

2. Run `/gsd:plan-phase 2` to create execution plans

3. Run `/gsd:execute-phase 2` to build CLI tool

### Infrastructure Decisions

1. **Go stdlib only** - No external dependencies for foundation
   - Rationale: Minimize binary size, keep it simple, 4.4MB result

2. **Port 32768** - High port for HTTP server
   - Rationale: Avoid conflicts with other Pi services

3. **Debian slim over Alpine** - debian:bookworm-slim as runtime base
   - Rationale: Better debugging capability, acceptable size tradeoff

4. **Static binary compilation** - CGO_ENABLED=0
   - Rationale: True cross-platform portability, no libc dependency

5. **Multi-stage Dockerfile** - Builder + runtime stages
   - Rationale: 95% smaller image, includes only runtime artifacts

6. **Non-root container user** - appuser UID 10001
   - Rationale: Security best practice, least privilege

### Development Workflow Decisions

7. **Docker Compose for dev** - Bind mount + hot reload
   - Rationale: Fast iteration without rebuilding images

8. **Air for hot reload** - Watches .go files, rebuilds to tmp/
   - Rationale: Standard Go hot reload tool, well-maintained

9. **Defer Docker verification** - User approved skipping runtime tests
   - Rationale: Corporate proxy blocks Docker Hub, will verify on Pi

</decisions_made>

## Active Blocker (Dev Machine Only)

**Docker Hub Registry Access**
- **Impact:** Cannot build or test Docker images on dev machine
- **Cause:** Corporate proxy blocks registry-1.docker.io
- **Error:** `proxyconnect tcp: EOF` when pulling golang:1.25-bookworm
- **Workaround:** Build and test on Raspberry Pi instead
- **Status:** Accepted - code verified via local Go builds
- **Resolution on Pi:** Pi network config likely allows registry access

## No Other Blockers

All code is complete and functional. No architectural blockers. No dependency issues.

## Development Environment Transition

This project was initialized and Phase 1 completed on a development machine with corporate network restrictions. The next session will be on the Raspberry Pi where the application will actually run.

## Why Docker Verification Was Deferred

The dev machine has a corporate proxy that blocks Docker Hub registry access. Rather than spend time fighting the proxy, we:

1. Verified all Go code compiles and runs locally
2. Validated all configuration files (YAML, TOML)
3. Cross-compiled to ARM64 to verify Pi compatibility
4. Created comprehensive handoff documentation

The risk is minimal because:
- Go code runs correctly on host
- Dockerfile follows official best practices
- Binary sizes are optimal (4.4MB)
- Configuration syntax is validated

## What Makes This Ready for Pi

- **Complete code artifacts** - All files exist and are substantive
- **Verified compilation** - Go builds work for both amd64 and arm64
- **Validated configs** - docker-compose.yml and .air.toml are valid
- **Best practices** - Multi-stage build, static binary, non-root user
- **Documentation** - HANDOFF.md has complete setup instructions

## Mental Model

The foundation layer is a minimal HTTP server that:
1. Serves on high port (32768) to avoid Pi conflicts
2. Has a health check that verifies /data volume is mounted
3. Compiles to a tiny static binary (4MB)
4. Runs in an isolated container as non-root user
5. Supports cross-platform builds for x86 and ARM

This sets up the infrastructure for Phase 2 (CLI tool) which will:
- Use the same /data volume for user database
- Share the same Go codebase (internal/ packages)
- Run in the same container (separate entrypoint)

## On Raspberry Pi - First Session

1. **Clone repository from Gitea:**
   ```bash
   git clone <gitea-url>/acty/pirate-station.git
   cd pirate-station
   ```

2. **Verify current state:**
   ```bash
   cat HANDOFF.md  # Read handoff instructions
   git log --oneline -10  # See recent commits
   ```

3. **Test Go build locally:**
   ```bash
   go build -o tmp/server ./cmd/server
   ./tmp/server
   # In another terminal: curl http://localhost:32768/health
   ```

4. **Build Docker image:**
   ```bash
   docker build -f docker/Dockerfile -t pirate-station:latest .
   docker images pirate-station:latest --format "{{.Size}}"
   # Should be under 150MB
   ```

5. **Complete Phase 1 verification checklist** from HANDOFF.md

6. **If all verifications pass:**
   ```bash
   /gsd:discuss-phase 2  # Start Phase 2 planning
   ```

7. **If Docker issues persist on Pi:**
   - Check Docker proxy settings
   - Try alternative registry (gcr.io)
   - Or continue with local Go builds until Phase 3 (when auth is needed)
