+# Pirate Station - Development Handoff
+
+**Date:** 2026-02-03
+**Phase:** Phase 1 (Foundation) Complete
+**Next:** Phase 2 (CLI Tool)
+**Environment:** Moving from dev machine to Raspberry Pi
+
+---
+
+## Current Status
+
+### ✓ Phase 1: Foundation Complete
+
+All code and configurations are ready. Docker runtime verification deferred to Pi deployment due to corporate proxy blocking Docker Hub access on dev machine.
+
+**Commits:**
+- `2691ded` - Go project with HTTP server and health check
+- `38edbf6` - Multi-stage Dockerfile for cross-platform builds
+- `257edf5` - Plan 01-01 completion
+- `6cbf414` - Docker Compose dev environment
+- `c09f4d7` - Plan 01-02 completion
+- `c8cd06b` - Phase 1 completion metadata
+
+**Requirements Delivered:**
+- ✓ **INFRA-01**: Docker container isolation design (runtime verification deferred)
+- ✓ **INFRA-02**: Single binary Go backend (fully verified)
+
+---
+
+## What Was Built
+
+### Go HTTP Server
+- **Location:** `cmd/server/main.go`, `internal/health/handler.go`
+- **Port:** 32768 (high port to avoid Pi service conflicts)
+- **Endpoints:**
+  - `/` - Returns "Pirate Station API"
+  - `/health` - Returns healthy when `/data` mounted, unhealthy otherwise
+- **Binary Size:** 4.4MB (amd64), 4.2MB (arm64) - stripped static binary
+- **Dependencies:** Go stdlib only (no external packages)
+
+### Docker Configuration
+- **Dockerfile:** `docker/Dockerfile`
+  - Multi-stage build (golang:1.25-bookworm → debian:bookworm-slim)
+  - CGO_ENABLED=0 for static binary
+  - Non-root user (appuser, UID 10001)
+  - Volume mount at `/data`
+  - Multi-arch support via buildx (amd64 + arm64)
+
+- **Compose:** `docker-compose.yml`
+  - Dev environment with hot reload
+  - Bind mount for live editing
+  - Named volume for persistent data
+
+- **Hot Reload:** `.air.toml`
+  - Watches Go files for changes
+  - Rebuilds automatically to `tmp/server`
+
+---
+
+## Known Blockers
+
+### Docker Hub Registry Access
+**Impact:** Cannot build/test Docker images on dev machine
+**Cause:** Corporate proxy blocks registry-1.docker.io
+**Status:** Deferred to Pi deployment
+
+**Resolution Options:**
+1. **Build on Pi** (Recommended) - Pi network config may allow registry access
+2. **Configure proxy** - Set `HTTP_PROXY`/`HTTPS_PROXY` in Docker daemon
+3. **Use mirror registry** - Modify Dockerfile to use gcr.io or quay.io
+4. **Manual base images** - Pre-pull images on different network
+
+---
+
+## First Run on Raspberry Pi
+
+### Prerequisites
+- Git configured on Pi
+- Docker installed
+- Go 1.22+ installed (for local builds)
+- Gitea set up (for future image pushes)
+
+### Steps
+
+1. **Clone repository on Pi:**
+   ```bash
+   git clone <gitea-url>/acty/pirate-station.git
+   cd pirate-station
+   ```
+
+2. **Verify Go build works:**
+   ```bash
+   go build -o tmp/server ./cmd/server
+   ./tmp/server
+   # In another terminal:
+   curl http://localhost:32768/
+   curl http://localhost:32768/health
+   ```
+
+3. **Build Docker image:**
+   ```bash
+   docker build -f docker/Dockerfile -t pirate-station:latest .
+   ```
+
+   If build succeeds, check image size:
+   ```bash
+   docker images pirate-station:latest --format "{{.Size}}"
+   # Should be under 150MB
+   ```
+
+4. **Test container isolation:**
+   ```bash
+   # Create test data volume
+   docker volume create pirate-data
+
+   # Run container
+   docker run -d --name pirate-test -p 32768:32768 -v pirate-data:/data pirate-station:latest
+
+   # Test endpoints
+   curl http://localhost:32768/
+   curl http://localhost:32768/health
+
+   # Verify health returns "healthy" (volume is mounted)
+
+   # Cleanup
+   docker stop pirate-test
+   docker rm pirate-test
+   ```
+
+5. **Test dev environment:**
+   ```bash
+   docker compose up --build
+   # Server should start on port 32768
+   # Edit cmd/server/main.go and watch for auto-rebuild
+   ```
+
+6. **Multi-arch build (optional):**
+   ```bash
+   docker buildx create --name pirate-builder --use
+   docker buildx build --platform linux/amd64,linux/arm64 \
+     -f docker/Dockerfile \
+     -t gitea.local/acty/pirate-station:latest \
+     --push .
+   ```

+
+## Next Steps: Phase 2 - CLI Tool
+
+**Goal:** Admin can manage user accounts via CLI
+
+**Requirements:**
+- CLI-01: Create user account
+- CLI-02: Delete user account
+- CLI-03: Change user password
+- CLI-04: List all users
+
+**Before planning Phase 2:**
+
+Run `/gsd:discuss-phase 2` to gather context and make decisions about:
+- User storage format (SQLite, JSON, etc.)
+- Password hashing algorithm (bcrypt vs argon2)
+- CLI tool structure (subcommands vs flags)
+- Where user database lives (in /data volume)
+
+**Or skip directly to planning:**
+
+Run `/gsd:plan-phase 2` if you want to proceed without discussion.
+

+
+## Key Decisions Made
+
+| Decision | Rationale |
+|----------|-----------|
+| Go stdlib only | Minimize binary size, maintain simplicity |
+| Port 32768 | High port avoids Pi service conflicts |
+| Debian slim base | Better debugging vs Alpine, acceptable size |
+| Health check verifies /data | Enables orchestration readiness probes |
+| Static binary (CGO_ENABLED=0) | True portability across platforms |
+| Non-root container user | Security best practice |
+| Multi-stage Dockerfile | 95% smaller image vs single-stage |
+| Docker Compose for dev | Bind mount + hot reload for fast iteration |
+

+## Verification Checklist for Pi
+
+When you first run on Pi, verify these items to confirm Phase 1 is fully complete:
+
+- [ ] Go binary compiles on Pi
+- [ ] Server starts and responds on port 32768
+- [ ] Health endpoint returns correct status
+- [ ] Docker image builds successfully (no registry errors)
+- [ ] Image size is under 150MB
+- [ ] Container runs as non-root user (appuser)
+- [ ] Container can only access /data volume
+- [ ] Host filesystem is isolated (cannot read /tmp/host-secret.txt from container)
+- [ ] Docker Compose dev environment starts
+- [ ] Hot reload detects Go file changes and rebuilds
+
+Once all items pass, Phase 1 verification is complete and Phase 2 can begin.
