# BUGS.md — open findings

Only the 2026-09-28 specification review (B-73 … B-100) still has open entries
(B-93). A finding is removed from this file once it is fixed, and
`git log --all --grep 'B-nn'` is the record of how it was closed. Per CLAUDE.md's
convention each entry gets its own commit with its own regression test, and the `B-nn`
marker goes in a comment next to the fix.

# Audit of 2026-09-28 — specification review (B-73 … B-98)

Fourth audit, run against the new specification in `docs/` rather than the code
alone: four independent reviews (coin/chain mechanics, money state machine,
DevOps, spec cross-validation), with the critical claims re-verified in code.
The target behaviour of every entry below is now written into `docs/` as
requirements marked `*Stato:* da implementare (B-nn)`; the Italian overview, the
design decisions and the implementation order are in
[docs/piano-correzioni.md](docs/piano-correzioni.md). The code has **not** been
changed yet. Same convention as above: one commit per entry, with its own
regression test, spec + code + test together.

Design decisions taken with the owner on 2026-09-28 (they change existing
decisions, see `docs/limiti-noti.md`):

- **Draw by commit-reveal.** The winner must not be computable by anyone who
  controls block production, since PLM's hashrate (~22 TH/s) is rentable.
- **Never release funds on doubt.** A money-moving row is rolled back only on proof
  (an explicit rejection, or its inputs confirmed-spent elsewhere), never on a
  timeout or on one server's silence.
- **One pool address per round**, so a round's money, history and payout are
  isolated from every other round's.
- **Deposits need 6 confirmations** (configurable), everything else keeps 1: the
  deposit is the only input a user can double-spend.
- **Contain reorgs instead of pretending they don't happen:** detect them, pause
  on deep ones, and pay out only what is verifiably on chain.

### B-93 — Deploys and rollbacks

A deploy with an open SSE stream never shuts down gracefully (uvicorn waits, Docker
kills after 10s); an older image cannot start on a newer DB; images are untagged;
`SITE_ADDRESS` passed per command reverts to `localhost` on the next plain
`docker compose up`.

Fix: close SSE streams on shutdown, `stop_grace_period: 30s`, await task
cancellation; tag images per release; `SITE_ADDRESS` in `.env` with `${SITE_ADDRESS:?}`;
documented pre-deploy backup and downgrade procedure.
