The round timer relied on each client's own wall clock, so two browsers with
skewed local clocks showed different countdowns for the same round; the
server now also returns server_time so the frontend can correct for clock
skew. Also drop out-of-order /rounds/current responses (multiple independent
triggers could resolve late and revert the UI to a stale drawing/result
state) and prune per-round bookkeeping maps on round transitions.
Separately, place_bet only checked status == "open", leaving a window (up to
the scheduler's 5s tick interval) after a round's timer hit zero where a new
bet could still be accepted. place_bet now checks the round's own deadline
directly (round_accepts_bets), acting as an immediate "yellow light" for new
entries while still letting already-broadcast bets confirm before the round
closes.

Session hardening: / and /admin now respond with Cache-Control: no-store, and
both pages re-derive their auth state on pageshow (event.persisted) as a
safety net against bfcache showing a stale logged-in/out view across
back/forward navigation. The user page also syncs logout across tabs via the
storage event, since localStorage is shared but in-memory JS state isn't.
Password recovery: admin gets a "Reset" button per user (POST
/admin/users/{id}/reset-password) that generates and sets a new password,
shown once — passwords are Argon2-hashed and can never be recovered, only
replaced. Users get self-service password change (POST
/users/me/change-password, requires the current password) under a new
Profilo tab, alongside read-only account info (username, address, balance,
join date).
Round display robustness: the user dashboard now refreshes immediately on
tab visibility change (background tabs get their timers throttled hard),
shows an explicit "connessione persa" state after repeated failed polls
instead of silently freezing on stale data, and polls faster both right when
the countdown hits zero and through the gap where the round is past its
deadline but still waiting for in-flight bets to confirm before the server
actually closes it.
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.
The user page's login screen was a bare test dashboard with no explanation
of how the lottery works; it now leads with a hero (3-step explainer, trust
pills) shown only while logged out, plus a bento-style nav and a glowing
round card during the draw.
Both the user and admin pages now show the current chain tip height and
lottery status (open / drawing / waiting for next round) via a small status
strip, polled from /rounds/current (extended with chain_tip_height sourced
from ElectrumListener.tip_height).
_close_and_draw set round_.status = "closing" but then immediately
overwrote it in memory with "closed" (no participants) or "drawing"
(with participants) before the first session.commit() — so "closing"
was never actually written to the database, only ever visible in the
ORM object's transient in-memory state. GET /rounds/current (and the
frontend's "in chiusura" label) could never observe it.
Committing right after setting "closing"/closed_at, before querying
participants, makes it a real, briefly-observable state like the
others in the round lifecycle.

When the round leaves "open" (closing/drawing/paying_out), the round
card swaps its timer for a spinning "Estrazione del vincitore in
corso…" state instead — bets are already rejected server-side once the
round isn't open, this just reflects that visually. Once winner_user_id
is set AND at least draw_animation_seconds has elapsed since the round
started closing (client-tracked per round_id), it reveals "🎉 Hai
vinto! +N PLM" (compared against the user's own id from /users/me) or
"Non hai vinto questa volta.", with a success toast on a win. The
result stays on screen through the cooldown gap and only clears once a
genuinely new round opens (tracked via activeResultRoundId), not the
instant the old round has no active status.
Polling is now dynamic (setTimeout-chained, not setInterval): 3s while
the round is closing/drawing/paying_out for a responsive reveal, 15s
while open.

RoundConfig gains draw_animation_seconds (default 20) — the minimum
time the frontend's "estrazione in corso" animation plays before
revealing a winner. It's purely a UI cue: the real draw still waits for
a confirmed block for its entropy (rounds/scheduler.py), which usually
takes much longer than this value, so it only ever extends the
animation, never truncates the real wait.
GET /rounds/current now also returns draw_animation_seconds,
winner_user_id and winner_amount_sats (all populated once the
scheduler sets them on the round, i.e. from "paying_out" onward) so a
client can determine and reveal the outcome. GET /users/me now returns
the user's own id, needed client-side to compare against winner_user_id.
Admin config CRUD refactored to a shared field tuple (_CONFIG_FIELDS)
instead of repeating the same 7-then-8 field list three times.

Replaces the single scrolling page with a sticky top navbar and five
sections: Parametri (all seven RoundConfig fields, now including round
duration/cooldown/min amount/fee rate/RBF timeout alongside fee address
and bet amount), Utenti (unchanged), Round (history: status, winner,
pool/winner/fee amounts, payout txid), Transazioni pendenti (in-flight
bet/payout/withdrawal txs), and Audit log (recent system events with
parsed payload). Everything loads on login; switching a nav tab
refreshes that section's data.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
GET /admin/rounds: recent rounds with status, winner (joined username),
pool/winner/fee amounts, payout txid. GET /admin/pending-transactions:
in-flight bet/payout/withdrawal txs (RBF candidates). GET /admin/audit-log:
recent audit_log entries with parsed payload. All gated by the existing
require_admin dependency, feeding the new dashboard sections.

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.

/admin now shows only a token field + "Accedi" button on first load —
config and users are structurally in the page but empty/hidden, no data
requested until the token is verified. On successful login (a GET
/admin/config that doesn't 403) it reveals the dashboard and loads
config + users automatically; no more separate "Carica configurazione"/
"Carica utenti" buttons. Token is kept in sessionStorage (cleared on
tab close) so a reload during the same session skips straight back to
the dashboard. Added a Logout button and Enter-to-submit on the token
field.

Registration now requires the password twice, rejected client-side on
mismatch before hitting the API. The admin page gets a Utenti card:
loads the user list (id, username, address, balance in PLM) and a
per-row "Mostra" button that reveals the private key after an explicit
confirm() — click again to hide it. A persistent warning banner notes
that every reveal is audit-logged.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
GET /admin/users lists id/username/address/balance_sats/created_at.
GET /admin/users/{id}/privkey derives and returns that user's raw WIF
private key, for manual intervention (e.g. sweeping funds back if
something's stuck) — this is already a custodial system, the server
holds the master key everything is derived from, so this doesn't grant
a new capability, just exposes an existing one through the API. Every
access is audit-logged (admin_privkey_accessed).
Also fixes a pre-existing test-isolation bug in test_admin.py's client
fixture: app.db.session.get_session had `from app.db.base import
AsyncSessionLocal`, a one-time reference copy at first import — later
tests reassigning db_base.AsyncSessionLocal never reached it, so any
test mixing direct DB writes with router calls silently read/wrote
against a stale, possibly-disposed engine from whichever test ran
first. Fixed by also rebinding app.db.session.AsyncSessionLocal in the
fixture on every run.

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.

A card above the section menu polls GET /rounds/current every 15s and
ticks a mm:ss countdown to closes_at every second locally, showing
status (aperto/in chiusura/estrazione/pagamento), participant count
and jackpot in PLM. Refreshed immediately after placing a bet, and
timers are cleared on logout.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
GET /rounds/current returns the active round's id/status, opened_at/
closes_at (derived from ROUND_DURATION_SECONDS), participant count and
jackpot (participant_count * bet_amount_sats). No active round still
returns bet_amount_sats so clients can render a fixed-entry hint either
way.

Deposito/Bet/Prelievo are now separate panels behind a top nav instead
of one long scroll of cards, and the Deposito panel renders the
deposit address as a QR code (via GET /qr/{address}) alongside the
existing copy-to-clipboard address box.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
GET /qr/{address} renders the address as a PNG QR code (qrcode[pil]),
gated by a bech32-shaped regex since it's otherwise unauthenticated —
the address itself isn't sensitive, but this keeps it from being used
as an arbitrary text-to-QR service.

New visual system from the ui-ux-pro-max skill (gold/purple accents,
Fira Sans + Fira Code, light mode, WCAG AA contrast): card layout,
tabbed login/register, loading states on every button, and toast
feedback instead of a raw request/response JSON dump. The dump is gone
from both pages — diagnosing an error now means reading logs/app.log,
not staring at the page.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
All app and uvicorn logging now goes to logs/app.log (rotating,
10MB x5), and a catch-all exception handler logs full tracebacks there
before returning a generic 500 — so an error is traceable to its cause
without depending on how the process was launched. logs/ is gitignored,
like the other runtime artifacts.

Balance, withdrawal amount and bet_amount_sats are entered/displayed in
PLM in both static pages; conversion to sats happens client-side right

Moves the fee_address/bet_amount_sats config form out of the main test
UI into a dedicated admin.html, served by a GET /admin route

test UI in either direction: reachable only by knowing the URL.

Builds and broadcasts a user->external-address PSBT with change back to

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.

Places the fixed-cost bet into the current round: builds and broadcasts
