davideandClaude Sonnet 5.5 40ac490826 Safe restore from a backup: START_PAUSED and the derivation-gap check (B-90, REG-15, OPS-27)
START_PAUSED=true pauses the lottery as the operator before the scheduler exists.
On the first Electrum session the 20 derivation indexes past the highest
assigned one are looked up on every server; if any has history, registration
stays closed (503 registration_unavailable) and restore_gap_detected is
written, so a restored database cannot hand a lost user's address to a new one.

# 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
```
719 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").
