Adds BUGS.md: a severity-ordered backlog from the 2026-07-26 audit of every Python module, both static frontends and the Docker/Caddy deployment. Each entry carries symptom, root cause with file references, reproduction and a proposed fix, plus the regression test it needs — none of these are covered by the current suite. The five critical ones share a root cause worth stating up front: the code treats a broadcast as final and the Electrum connection as never failing, so there is no reconciliation between the DB's view and the chain's. That leaves several states the system only leaves via manual DB edits. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
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 for the full architecture, domain decisions, and known gaps before treating this as production-ready.
Quick start
cp .env.example .env # then fill in the generated secrets, see docs/setup.md
python3 -m venv .venv && source .venv/bin/activate
pip install -e ".[dev]"
PYTHONPATH=. python scripts/generate_master_key.py
alembic upgrade head
uvicorn app.main:app --reload --port 8123
Open http://127.0.0.1:8123/ for the test UI, http://127.0.0.1:8123/admin
for the admin dashboard, http://127.0.0.1:8123/docs for the interactive API
docs.
Or run the whole stack (app + Caddy reverse proxy with automatic TLS) via Docker:
mkdir -p data/db data/keys data/logs
docker compose run --rm app python scripts/generate_master_key.py
docker compose up -d --build
See docs/setup.md and docs/running-the-server.md for the full walkthrough (both workflows, dev vs. production TLS).
Documentation
- CLAUDE.md — architecture, commands, domain decisions, known gaps (for anyone/anything working on the code)
- flowchart.mmd — the source-of-truth flow diagram the implementation follows node-by-node
- docs/setup.md — one-time setup (secrets, master key, migrations)
- docs/running-the-server.md — how to launch it (local venv vs. Docker+Caddy, dev vs. production TLS)
- docs/guida-utente.md — end-user guide to the test UI (Italian)
- 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 for the complete list and the reasoning behind each choice.
Testing
python -m pytest # all tests
python -m pytest tests/unit/test_hd.py # one file
76 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").
