place_bet and request_withdrawal released everything on any exception from the broadcast, including the 15s timeout and a connection dropped after the write. The tx may have propagated: a bet's sats landed in the pool with no participant, a withdrawal left while its row said failed and its coins were spendable again. - client: ElectrumRpcError (subclass of ElectrumError) is raised only for a reply carrying a JSON-RPC `error`; timeouts, drops and write errors stay plain ElectrumError. - tx/outcome.py:broadcast_with_verdict sorts a broadcast into accepted / refused / uncertain. A refusal is verified first: ElectrumListener.transaction_known asks blockchain.transaction.get of the active server and every other one (10s each) — any server returning the tx means accepted; the active server plus MIN_QUORUM_RESPONSES others all denying it means refused (ALLOW_NO_QUORUM keeps the reduced rule); too few answers is uncertain. "already known" wording is only a shortcut that skips the check. With no network to ask, a refusal is uncertain. - place_bet / request_withdrawal / _trigger_payout use it: only a verified refusal releases; uncertain leaves the rows building for the reconciler, publishes SSE and POST /bets and POST /withdrawals answer 202 with status building; "already known" promotes a payout (payout_sent) like any accepted broadcast. - An accepted transaction is fanned out to every other server (ElectrumListener.fan_out_transaction, best effort, off the caller's path). The RBF replacement in bump_fee is left for B-77, which rewrites that function. Tests changed because the spec changed: the existing "refused broadcast" tests raised a bare RuntimeError (now an uncertain outcome) and are made explicit refusals (rpc_error) with a network that denies the tx; direct route calls pass a Response; FakePayoutListener gains the network surface.

# 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
|
|
```
|
|
|
|
463 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").
