davideandClaude Sonnet 5.5 b424f670c5 Restructure docs: docs-first, SSOT, one ADR per decision
- Add docs/README.md as the index of all documentation.
- Split the 52 DEC entries of decisioni-e-limiti.md into docs/adr/ADR-NN
  files (same numbers), add ADR-53 (audit log), TEMPLATE.md and an ADR index
  with a feature -> ADR table.
- Rename decisioni-e-limiti.md to limiti-noti.md (LIM only) and rewrite all
  DEC-nn references as links to the ADRs.
- Document the docs-first / SSOT / ADR rules in processo-di-modifica.md and
  map the docs in CLAUDE.md and README.md.

# PLM Lottery
A periodic-round lottery system built on PLM, a Bitcoin-like coin (mainnet).
Each user gets a dedicated server-derived P2WPKH address; they deposit PLM to
that address, place a fixed-cost bet to enter the current round, and when the
round closes a winner is drawn who receives 70% of the prize pool (the
remaining 30% goes to fees).
This is a **custodial** system: private keys are generated and held
server-side, encrypted at rest. See [CLAUDE.md](CLAUDE.md) for the full
architecture, domain decisions, and known gaps before treating this as
production-ready.
## Quick start
The server always runs via Docker (app + Caddy reverse proxy with automatic
TLS) — in dev and production alike, with only `SITE_ADDRESS` differing
between the two. There's no supported way to run `uvicorn` directly; the
venv is only for local tooling (tests, Alembic migrations, the one-time key
scripts) — see [CLAUDE.md](CLAUDE.md#commands).
```bash
cp .env.example .env # then fill in the generated secrets, see docs/setup.md
mkdir -p data/db data/keys data/logs
docker compose run --rm app python scripts/generate_master_key.py
docker compose up -d --build
```
Open `https://localhost/` for the test UI, `https://localhost/admin` for the
admin dashboard (a self-signed-certificate warning on first visit is
expected in dev — accept it, or use `curl -k`). The interactive API docs at
`/docs` are disabled by default (they'd otherwise expose the whole API
surface, admin endpoints included) — set `ENABLE_API_DOCS=true` in `.env` to
enable them.
See [docs/setup.md](docs/setup.md) and
[docs/running-the-server.md](docs/running-the-server.md) for the full
walkthrough (secrets, master key generation, production TLS with a real
domain).
## Documentation
- [CLAUDE.md](CLAUDE.md) — architecture, commands, domain decisions, known gaps (for anyone/anything working on the code)
- [docs/README.md](docs/README.md) — **index of all documentation** (docs-first, single source of truth, one ADR per decision: [docs/adr/](docs/adr/README.md))
- [docs/come-funziona.md](docs/come-funziona.md) — the specification (Italian): how the platform works, with diagrams and traceable requirement IDs; it indexes every per-topic document (flows, architecture, data model, API, security, audit log, operations, decisions and limits, bug history). [docs/processo-di-modifica.md](docs/processo-di-modifica.md) describes how a change goes from the spec to the code
- [docs/setup.md](docs/setup.md) — one-time setup (secrets, master key, migrations)
- [docs/running-the-server.md](docs/running-the-server.md) — how to launch it with Docker+Caddy (dev vs. production TLS)
- [docs/guida-utente.md](docs/guida-utente.md) — end-user guide to the test UI (Italian)
- [docs/guida-admin.md](docs/guida-admin.md) — admin dashboard guide (Italian)
## Tech stack
Python (FastAPI, SQLAlchemy async + Alembic, Argon2 + JWT auth), Electrum
protocol for PLM network access (no full node), Docker + Caddy for
deployment. See [CLAUDE.md](CLAUDE.md#tech-stack) for the complete list
and the reasoning behind each choice.
## Testing
```bash
python -m pytest # all tests
python -m pytest tests/unit/test_hd.py # one file
```
388 unit tests cover HD derivation, PSBT building, the Electrum client, bets,
deposits, withdrawals, the round/draw engine, RBF fee-bumping, admin config,
the pending-inclusive balance calculation, and the SSE push channel. No
automated integration tests against a live Electrum connection — mainnet
verification so far has been manual (see CLAUDE.md's "Project status").
