Round opening (B-09). open_new_round_if_needed now handles the IntegrityError
from ix_rounds_single_active (previous commit) by rolling back and using the
winner's round. Deviation from the plan in BUGS.md, which proposed making the
scheduler the only writer: that would mean the first bet after a cooldown
couldn't open a round, so both callers stay and a bounded retry was added
instead — a conflict where nothing is active yet just means the winner hadn't
committed, and a bet must not fail on that timing. get_active_round also logs
loudly if it ever sees more than one active round rather than silently picking
the newest.
The jackpot (B-11). It was participant_count * the *current* bet_amount_sats,
which overstated the pool (each stored bet is already net of that bet's network
fee) and silently rewrote the advertised jackpot of a round in progress whenever
an operator edited the bet amount. It now sums the participants' stored
bet_amount_sats. The remaining imprecision — the payout tx's own fee, deducted
from the winner's share and unknowable until the payout is built — is documented
in the code rather than promised away, since the comment there claimed exactness.
Payout (B-05, B-18). _trigger_payout is split into read / build+broadcast /
persist, so no DB session is held across a network call (on SQLite that meant
holding the write lock for two unbounded round-trips). That restructuring is also
what makes the error handling placeable: it now catches Exception around the
chain work and writes a payout_failed audit entry, where a malformed fee_address
used to raise EmbitError all the way to the scheduler's catch-all, leaving the
round stuck in paying_out with nothing recorded about why. Automatic payout retry
remains an open gap.
The scheduler also counts "building" participants as in-flight when deciding
whether a round may close, matching the two-phase bet write.

RoundConfig gets a paused flag toggled via new POST /admin/pause and
/admin/resume endpoints (audit-logged, surfaced as a "Manutenzione" card in
the admin Parametri view). Pausing only stops the *next* round from opening
once the current one closes — rounds/service.py:open_new_round_if_needed
still lets an in-progress round finish, draw, and pay out its winner
normally. GET /rounds/current exposes lottery_paused so the user page shows
a maintenance banner (even while logged out) instead of silently going idle.
Also replaces the user dashboard's stacked account-bar card + bento-grid
menu with a single sticky navbar (identity row + Deposito/Bet/Prelievo
tabs), and moves the page content into a dedicated .app-shell container so
the navbar itself can span full width.
RoundConfig gains round_duration_seconds, round_cooldown_seconds,
min_amount_sats, fee_rate_sat_vb and rbf_timeout_seconds (plus a
hardcoded default for the pre-existing bet_amount_sats) as column
defaults on the model itself — get_round_config no longer seeds from
Settings at all. Every call site that read these from settings
(scheduler, bets, withdrawals, rounds service/route, RBF bumper) now
reads the DB-backed RoundConfig instead.
app/config.py now holds only true env-driven infra/secrets (database
URL, Electrum connection, master key, JWT, admin token) — no business
parameter has an env var anymore, matching an explicit decision to drop
the "seed from settings" indirection entirely rather than keep a env
fallback nobody should rely on.
Migration backfills the existing round_config row via server_default
(matching the old settings defaults) then drops the default, so future
rows go through the ORM/model defaults instead of a stale constant.
Tests updated: should_bump's timeout_seconds is now required (no
settings fallback); test_scheduler.py seeds a RoundConfig row directly
instead of monkeypatching settings; test_withdrawals.py and
test_rounds_service.py use local constants mirroring the model
defaults instead of reading them off settings.

open_new_round_if_needed now withholds opening the next round until
ROUND_COOLDOWN_SECONDS (default 30) have passed since the previous
round's closed_at, returning None in that window instead of a Round.
Without this, the next round opened within one scheduler tick (~5s) of
the previous payout confirming — not enough time for a player to
notice the round they were in actually resolved.
Callers updated: the scheduler treats None as "nothing to do this
tick", and place_bet raises a "try again shortly" BetError instead of
crashing on a None round.
Not in the original flowchart — a deliberate UX addition on top of it,
documented as such in CLAUDE.md.

Periodic scheduler (configurable round duration) that closes a round
only once all broadcast bets confirm, waits for the next block after
closing, draws a winner via block-hash-seeded modulo over participants
ordered by broadcast time, triggers the 70/30 payout, and only opens the
next round once that payout confirms. Draw logic is isolated in
draw.py as a deliberately simple, replaceable component.
