Mirrors the earlier CSS extraction (style.css/admin.css) — app/static/ is
now split cleanly by file type (markup, styles, script) instead of mixing
JS inline in the HTML. No behavior change: the script content moved
verbatim, referenced via <script src>. FastAPI's existing StaticFiles mount
serves the new files automatically, same as the CSS files already do.

CLAUDE.md: bumped the stale test count (54 -> 76), added "Balance display"
and "Real-time updates (SSE)" sections, and rewrote the DRAW section's
frontend-reveal paragraph to describe the actual current behavior (dual
status/result boxes gated by user_played, closes_at-anchored reveal delay,
localStorage persistence, the last-round-result backstop) instead of the
older single-box design. Refined the "no history endpoints" known gap now
that GET /users/me/last-round-result exists (still not general history).
README.md: same test count fix, expanded coverage list.
docs/: fixed a pre-existing broken link in setup.md (admin-guide.md ->
guida-admin.md), added a note in running-the-server.md that editing the
bind-mounted Caddyfile needs an explicit `docker compose restart caddy`
(discovered while adding the SSE Caddy config in a prior change), and
rewrote guida-utente.md's draw/reveal section plus the balance/withdrawal
sections to match what the UI actually does now. guida-admin.md was
reviewed but needed no changes.
app/static/style.css: dropped `.toast.info`, dead since the toast-based
loss notification it styled was replaced by the persistent result box.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
app/static/index.html: opens an EventSource against /rounds/stream (no auth
needed, see the previous commit) alongside the existing polling loops. On an
"update" notification, immediately re-runs the same refreshes polling would
eventually do (refreshRound/refreshMe/checkLastRoundResult when logged in,
refreshChainStatusOnly when logged out). Also reacts to the browser's "open"
event, which fires on the initial connection and on every automatic
reconnect — this re-syncs right away instead of leaving the page on stale
state until the next event or poll tick, which matters most right after a
dropped connection comes back.
app/static/admin.html: same channel, refreshing the chain-status bar and
whichever admin section is currently open (Utenti/Round/Transazioni
pendenti/Audit log) instead of requiring a manual tab switch to see new data.
Polling intervals are untouched in both pages — this is purely additive, so
a blocked/dropped SSE connection just degrades to the pre-existing behavior.

Frontend dashboards previously found out about state changes only on their
next poll tick (up to 15s, or 3s during a draw) — this adds a push channel
so updates land as soon as they happen instead.
- app/rounds/events.py: a small in-process pub/sub (RoundEventBroadcaster).
The message carries no payload — it's just a "something changed, go
refetch" signal, so it needs no auth and no knowledge of who's allowed to
see what; personalization stays entirely in the existing REST endpoints.
- GET /rounds/stream: an SSE endpoint exposing that channel, with keep-alive
comments so it survives idle periods behind a reverse proxy, and a
defensive MAX_SUBSCRIBERS cap (well above the ~100 concurrent users
expected) — past it, the endpoint returns 503 instead of opening a stream,
and callers just keep working off polling.
- publish() calls added at every point that actually changes what a
dashboard would want to know: new round opened, round status transitions
(closing/drawing/paying_out/closed), a bet or withdrawal broadcast, any
pending tx confirming (bet/withdrawal/payout), a deposit credited, and a
new block tip arriving (the exact moment the "drawing" phase is waiting on).
- Caddyfile: excludes /rounds/stream from gzip encoding, since compression
would buffer output and defeat the point of a live stream.
Single-process only by design for now (no cross-worker fan-out) and the
notification is a generic broadcast rather than a per-user channel — both
are deliberate scope decisions for the current ~100-user, single-container
deployment, not oversights. Polling is left fully in place as a fallback;
this is purely additive.

Balance display: place_bet/request_withdrawal spend whole UTXOs and mark
them spent at broadcast time, well before confirmation, so the confirmed-only
balance could drop by far more than the amount actually moving. Add
compute_pending_balance() (app/wallet/balance.py) to fold the unconfirmed
change from in-flight bet/withdrawal PendingTransactions back in; GET
/users/me now returns pending_balance_sats + has_pending, and the frontend
shows it colored green (settled) or amber (still pending) instead of the
confirmed-only figure.
Round outcome display: the win/lose reveal and the "pagamento al vincitore
in corso" status were fighting over the same UI slot, and the reveal broke
across a page refresh. Now:
- The round-status box (generic phase progress) and the personal win/lose
box are independent and can both be visible at once.
- The win/lose box only renders for users who actually played in that round
(new user_played field on GET /rounds/current, via a new optional-auth
dependency so the endpoint stays usable logged-out).
- The reveal delay is anchored to the round's server-provided closes_at
instead of a client-side "first seen" timestamp, so repeated reloads can't
reset it, and the revealed result is persisted in localStorage so it
survives a refresh even after the round has fully closed.
- GET /users/me/last-round-result is a durable DB-backed backstop for
players who miss the live window entirely (backgrounded tab, offline).
Also hardens the frontend polling loop: call() now times out instead of
hanging forever, and a session-epoch counter stops an in-flight request from
a previous login from resurrecting a duplicate poll loop after logout.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
- Add a request timeout (AbortController) to the frontend's call() helper, so a
hung server request no longer freezes the entire polling chain silently.
- Add GET /users/me/last-round-result: a durable, DB-backed fallback for the
round outcome, since /rounds/current drops winner_user_id the instant a
round flips from "paying_out" to "closed" — a backgrounded tab or a missed
poll could otherwise mean a player never learns whether they won.
- Refresh the balance display when a win is revealed (live or via the new
backstop), instead of leaving the pre-payout balance on screen.
- Guard refreshRound() with a session-epoch counter so an in-flight request
from a previous login can't re-arm the poll loop after logout, which
previously produced a duplicate "zombie" polling chain.
The draw-state panel and the top chain-status bar previously showed the
same "Estrazione in corso" text for closing/drawing/paying_out alike. Now
each phase gets its own copy (closing: waiting for last bet confirmation;
drawing: waiting for the draw block; paying_out: winner drawn from block
#N, payout in flight), using the round data already returned by the API.
Also drops the now-redundant pastDeadline fast-poll branch: status flips
to "closing" the instant the timer expires (see the scheduler change),
so isDrawing alone already covers that window.
Flip status to "closing" the instant the round timer expires, rather than
leaving it "open" (invisible) while in-flight bets confirm — /rounds/current
now surfaces this wait as its own phase instead of collapsing it into
"drawing". _tick() is updated to keep re-checking pending bets while status
is "closing" instead of short-circuiting on the old "status != open" guard.
Also re-stamp closed_at at actual payout confirmation time (not at the
earlier "closing" transition), since round_cooldown_seconds counts from
closed_at — with a short cooldown (e.g. 20s) and ~2 block-time draw+payout
wait, the old anchor meant the cooldown had already elapsed by the time the
round actually closed, making it a no-op.
Expose draw_block_height/draw_block_hash on GET /rounds/current so clients
can show which block the winner was drawn from.
RoundConfig.min_amount_sats was an independently-configurable floor that
could drift out of sync with bet_amount_sats for no real reason (deposits
never had a server-side minimum anyway). Drop the field and enforce
amount_sats >= config.bet_amount_sats directly in request_withdrawal.

Adds app/static/logo.svg — the official Palladium logo (fetched from the
palladium-coin/palladium-web-site repo), reprocessed for crisp display at
small sizes: the white/blue boundary is sharpened (steep contrast curve
instead of the soft anti-aliasing baked into the low-res source) and the
outer circle uses an analytically computed alpha edge instead of a
rasterized ellipse, so it stays perfectly round with no pixel staircase at
any size. Shape and colors are otherwise identical to the source artwork.
Wired up as the navbar brand mark (replacing the plain amber "P" square) in
index.html, and as the favicon for both index.html and admin.html.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Checking it disables the amount field, autofills it with the current
balance, and keeps it in sync if the balance changes while checked. The
actual withdrawal request uses the raw balance_sats value directly instead
of round-tripping through the PLM input field, avoiding float-rounding
drift when withdrawing the exact full balance.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
GET /rounds/current's jackpot_sats was the full pool (participant_count *
bet_amount_sats), which overstates what the winner actually receives once
the 30% commission is taken out at payout time. Apply the same 70% split
rounds/scheduler.py uses so the number shown during the round already
matches the real payout, without surfacing the fee itself in the UI/docs.

Restructures app/static/index.html's visual design without touching any JS
logic or element IDs:
- Typography switched to IBM Plex Sans (financial/trustworthy pairing),
Fira Code kept for addresses and numeric mono values.
- Design tokens extended with elevation shadows, an inset-surface color,
and a scaled border-radius system; cards/buttons get subtle depth instead
of flat borders.
- Navigation goes adaptive: a native-app-style fixed bottom tab bar on
mobile (thumb-reachable), promoted back to an inline tab strip once the
viewport is wide enough (>=720px) to fit one comfortably under the header.
- Top bar decluttered: balance shown as a highlighted pill (icon + value),
Guida/Segnala un bug/Esci condensed into icon buttons with tooltips and
aria-labels instead of full-text links.
- Round-status card gets a subtle gradient "hero" treatment to read as the
central live widget of the dashboard.
- Content width now adapts from 480px (mobile) to 620px (>=720px) instead
of staying phone-narrow on desktop; safe-area insets reserved for the
fixed bottom bar and toast stack.

Adds a navbar-balance span next to the username, kept in sync by the
existing refreshMe() calls (login, after a bet, after a withdrawal, manual
refresh) — no new endpoint needed, /users/me already returns balance_sats.

Serves docs/guida-utente.md as plain text at GET /guida (no markdown

embit's address_to_scriptpubkey only knows Bitcoin's network prefixes, not
PLM's — so a legacy P2PKH address (prefix 55, "P...") silently produces a
None scriptpubkey instead of a clear rejection, and P2SH only works by
coincidence. Until the address decoding is fixed to use PLM's own network
prefixes, surface the current limitation to users in the withdrawal form
and the user guide instead of letting them lose funds to a broken address.

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.
Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
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.

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

timers are cleared on logout.

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

way.

Deposito/Bet/Prelievo are now separate panels behind a top nav instead

GET /qr/{address} renders the address as a PNG QR code (qrcode[pil]),

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.

All app and uvicorn logging now goes to logs/app.log (rotating,

Periodic scheduler (configurable round duration) that closes a round
