Add crosspoll_state table to persist per-island generation counters across evolver restarts. Load state on startup and save after each cross-pollination check. Add persistence pattern and translation structure tests. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

# acb-starter-python
|
|
|
|
Python 3 starter kit for [AI Code Battle](https://aicodebattle.com) — a competitive bot programming platform.
|
|
|
|
## Quick Start
|
|
|
|
```bash
|
|
# Run locally
|
|
pip install -r requirements.txt
|
|
BOT_SECRET=dev-secret python3 main.py
|
|
|
|
# Run with Docker
|
|
docker build -t my-bot .
|
|
docker run -e BOT_SECRET=your-secret -p 8080:8080 my-bot
|
|
```
|
|
|
|
Your bot listens on port 8080 and responds to `POST /turn` with move commands.
|
|
|
|
## Register Your Bot
|
|
|
|
Once your bot is deployed and accessible via HTTPS:
|
|
|
|
```bash
|
|
curl -X POST https://api.aicodebattle.com/api/register \
|
|
-H "Content-Type: application/json" \
|
|
-d '{
|
|
"name": "my-python-bot",
|
|
"endpoint_url": "https://my-bot.example.com",
|
|
"owner": "your-name",
|
|
"description": "My awesome bot"
|
|
}'
|
|
```
|
|
|
|
Save the `bot_id` and `shared_secret` from the response — the secret is shown only once.
|
|
|
|
## Project Structure
|
|
|
|
```
|
|
main.py # HTTP server, HMAC auth, and strategy entry point
|
|
grid.py # Grid utilities (toroidal distance, BFS, neighbors)
|
|
requirements.txt # Python dependencies (stdlib only for this starter)
|
|
Dockerfile # Container build
|
|
```
|
|
|
|
## Grid Helpers
|
|
|
|
`grid.py` provides utility functions for the toroidal grid:
|
|
|
|
- `toroidal_manhattan(r1, c1, r2, c2, cols, rows)` — Manhattan distance with wrap-around
|
|
- `toroidal_chebyshev(r1, c1, r2, c2, cols, rows)` — Chebyshev distance with wrap-around
|
|
- `neighbors(row, col, rows, cols)` — 8-directional neighbors with wrap
|
|
- `bfs(start, goal, passable, rows, cols)` — BFS pathfinding, returns path or `None`
|
|
|
|
## Customization
|
|
|
|
Edit `compute_moves()` in `main.py` to implement your strategy. The `GameState` object provides:
|
|
|
|
- `bots` — all visible bots (yours and enemies)
|
|
- `energy` — visible energy pickup locations
|
|
- `cores` — visible core positions
|
|
- `walls` — visible wall positions
|
|
- `you_energy` — your current energy count
|
|
- `you_score` — your current score
|
|
- `config` — match parameters (grid size, etc.)
|
|
|
|
Return a list of moves, each with `position` (your bot's current position) and `direction` (`"N"`, `"E"`, `"S"`, or `"W"`). Bots not included in the moves list stay in place.
|
|
|
|
## Protocol
|
|
|
|
- **Endpoint:** `POST /turn` — receives game state JSON, returns moves JSON
|
|
- **Health:** `GET /health` — must return 200
|
|
- **Timeout:** 3 seconds per turn
|
|
- **Auth:** HMAC-SHA256 via `X-ACB-Signature` header
