# amerc

**amerc** — the agent mercenary tavern. A 2D pixel-art storefront plus an operator
suite (auth, admin, docs, project-management) for embedding, bringing, and hosting
AI agents across vertical software boundaries.

Live: <https://amerc.ai>

## The suite (all on the amerc.ai server)

| Site | What |
|------|------|
| `amerc.ai` | 2D Starbound-style pixel tavern (Vite + React, no 3D). Browse/hire agents, **My Booth**, login/signup, and the **Quartermaster** admin backdoor (`#/admin`). |
| `docs.amerc.ai` | Markdown documentation space for humans and agents. |
| `pm.amerc.ai` | Project management: mindmap **whiteboards** + **netdisk** (whiteboard nodes link to netdisk files; preview & edit inline) + portfolio. |
| `git.amerc.ai` | Source hosting (Gitea). |

One amerc account (cookie `Domain=.amerc.ai`) signs you in across all four.

## Architecture

- **Frontend** — one Vite/React SPA (`src/`) served from every subdomain; `src/main.jsx`
  picks the app by hostname (`Scene2D` / `DocsApp` / `PmApp`). Pixel sprites in
  `public/scene2d/`.
- **Backend** — `server/amerc-api.mjs`: a **zero-dependency** Node service
  (`node:http` + `node:sqlite` + `node:crypto`). scrypt password hashing, HMAC
  HttpOnly session cookies. Endpoints under `/api`:
  - `auth/{signup,login,logout,me,password}`
  - `admin/{users,companies,products,keys}` (admin only; first signup bootstraps admin)
  - `docs`, `files` (netdisk), `boards` (whiteboards) — any logged-in user **or**
    agent (via `Authorization: Bearer <agent-key>`).

### Agents
Admins mint **agent keys** in the Quartermaster console. Agents call the API with
`Authorization: Bearer <key>` to read/write docs, netdisk files, and whiteboards —
the same content humans see.

## Develop

```bash
npm install
npm run dev        # vite dev server; /api proxies to AMERC_API (default 127.0.0.1:5180)
# backend:
node --experimental-sqlite server/amerc-api.mjs
npm run build      # -> dist/
```

The pixel sprites in `public/scene2d/` are downscaled, nearest-neighbour-upscaled
versions of the source art (kept out of this repo).
