# GreenCoast — Privacy-First, Shardable Social (Dockerized)

**Goal:** A BlueSky-like experience with **shards**, **zero-trust**, **no data collection**, **E2EE**, and easy self-hosting — from x86_64 down to **Raspberry Pi Zero**.  
License: **The Unlicense** (public-domain equivalent).

This repo contains a minimal, working **shard**: an append-only object API with zero-data-collection defaults. It’s structured to evolve into full federation, E2EE, and client apps, while keeping Pi Zero as a supported host.

## Quick Start (Laptop / Dev)

**Requirements:** Docker + Compose v2

```bash
git clone <your repo> greencoast
cd greencoast
cp .env.example .env
docker compose -f docker-compose.dev.yml up --build
# Health:
curl -s http://localhost:8080/healthz
# Put an object (dev mode allows unauthenticated PUT/GET):
curl -s -X PUT --data-binary @README.md http://localhost:8080/v1/object
# -> {"ok":true,"hash":"<sha256>",...}
curl -s http://localhost:8080/v1/object/<sha256> | head
