Two concurrency fixes from the 2026-07-06 review (findings M1, M2):
sync push (M1): the load→merge→store cycle ran as three separate DB
operations. Two devices pushing concurrently both read the same stored
payload, merged independently, and the second store overwrote the first
merge — the server visibly regressed until the losing device pushed
again. The whole cycle (including the leaderboard update) now runs in
one transaction; SQLite serialises the writers. The leaderboard
helper's stale docstring (claiming a single conditional UPDATE that was
actually two statements) is corrected — the transaction now provides
the atomicity it described.
refresh rotation (M2): SELECT-then-DELETE let two concurrent refreshes
with the same token both pass the liveness check and both mint fresh
token pairs. The SELECT is gone; rotation now gates on the DELETE's
rows_affected — whoever removes the jti row wins, everyone else gets
401. Sequential reuse was already covered by
consumed_refresh_token_is_rejected, which still passes unchanged.

- Apply cargo fmt to solitaire_engine, solitaire_server formatting.
- solitaire_server/src/lib.rs: add https://analytics.aleshym.co to
script-src, img-src, and connect-src so the analytics beacon loads
without a CSP violation.
- docs and README updates.

- sync.rs: replace Uuid::nil() placeholder with the authenticated
user's real UUID before the mismatch check so desktop client pushes
no longer fail with 400 user_id mismatch (#73)
- replays.rs: use server-computed received_at instead of client-supplied
header.recorded_at when updating leaderboard recorded_at to prevent
timestamp spoofing (#74)

- #66: Clamp safe-area insets to 25% of window height with warn!() on excess
- #68: Move fire_flush outside per-event loop in analytics (batch flush once)
- #56: Persist progress before marking reward_granted to prevent XP loss on crash
- #60: Add DateRolloverTimer + check_date_rollover system for midnight seed refresh
- #62: Add validate_header() in replay upload with mode/draw_mode allowlists
- #61: Restore two-query leaderboard opt-in check (SELECT then UPDATE); original
queries already in .sqlx cache; EXISTS variant would require sqlx prepare

- Introduce AppState { pool, jwt_secret } so JWT_SECRET is loaded once in
main() and any missing value is a fatal startup error rather than a 500
on the first request. All four env::var("JWT_SECRET") call sites in
auth.rs and middleware.rs are replaced with state.jwt_secret.
- build_test_router embeds the fixed test secret so integration tests do
not need to set JWT_SECRET in the environment.
- Add tracing::warn! in login (invalid password) and register (username
taken) to surface brute-force attempts in production logs.
- Fix daily-challenge race condition: after INSERT OR IGNORE, re-SELECT
the persisted row so concurrent requests both return the winner's data.

P0 fixes:
- Register WinSummaryPlugin, SelectionPlugin, CardAnimationPlugin in main.rs
(all three were exported but never wired — features silently did nothing)
- game_state::draw(): increment move_count on waste→stock recycle, not just
on normal draws; add move_count_increments_on_recycle regression test
P1 fixes:
- solitaire_server/Cargo.toml: remove duplicate dev-dependencies
(solitaire_sync, uuid, chrono, jsonwebtoken were in both sections)
P2 — input_plugin refactor:
- Split 198-line handle_keyboard() into three focused systems under 110 lines each:
handle_keyboard_core (U/N/Z/D/Space), handle_keyboard_hint (H), handle_keyboard_forfeit (G)
- Introduce KeyboardConfirmState resource to share countdown timers across systems
- Add three new unit tests: all_hints_suggests_draw_*, all_hints_is_empty_when_truly_stuck,
new_game_confirm_window_is_positive
P2 — achievement predicate tests (solitaire_core):
- Add 10 direct unit tests for speed_demon, lightning, no_undo, high_scorer,
on_a_roll, comeback predicates (previously only covered via check_achievements())
- 141 core tests now passing
P2 — server tests:
- solitaire_server/src/sync.rs: 4 unit tests for merge logic (no DB required)
- solitaire_server/src/leaderboard.rs: 2 unit tests for entry shape and sort order
P3 — documentation:
- Add struct-level /// to 12 Plugin structs (ChallengePlugin, CursorPlugin,
AnimationPlugin, HelpPlugin, PausePlugin, AudioPlugin, DailyChallengePlugin,
HudPlugin, LeaderboardPlugin, OnboardingPlugin, TimeAttackPlugin, WeeklyGoalsPlugin)
- Add field-level /// to Card, Pile, Deck, GameState, AchievementContext, AchievementDef
- Add /// to WeeklyGoalKind, WeeklyGoalDef, WeeklyGoalContext, StatsExt::update_on_win
card_animation module (new files from previous session):
- chain.rs, diagnostics.rs, tuning.rs, updated interaction.rs/animation.rs/mod.rs/lib.rs
- Remove unused HOVER_SCALE_DEFAULT / DRAG_LIFT_SCALE_DEFAULT / HOVER_LERP_SPEED_DEFAULT constants
- Add handle_touch_stock_tap so touch users can draw from the stock pile

When a user pushes sync data and is opted in to the leaderboard, the
server now updates their leaderboard row with the merged stats using
MAX(best_score) and MIN(best_time_secs) — scores never regress even if
the client sends stale data.
Eliminates the need for a separate score-submission API call: the sync
push already carries the full stats, so the leaderboard stays current
after every push.
Added two integration tests:
- push_after_opt_in_updates_leaderboard_score
- push_lower_score_does_not_overwrite_leaderboard_best

- solitaire_server: Axum auth, sync push/pull, leaderboard, daily
challenge, account deletion, JWT middleware, rate limiting via
tower_governor, SQLite migrations, health endpoint
- solitaire_server: expose build_test_router (no rate limiting) so
integration tests work without a peer IP in oneshot requests
- solitaire_sync: SyncPayload, merge logic, shared API types
- solitaire_data: SyncProvider trait, LocalOnlyProvider,
SolitaireServerClient, auth_tokens keyring integration, blanket
Box<dyn SyncProvider> impl
- solitaire_data/settings: derive Default on SyncBackend (clippy fix)
- .sqlx/: offline query cache so server compiles without a live DB
- sqlx: removed non-existent "offline" feature flag
- keyring v2: fixed Entry::new() returning Result<Entry>
- sqlx 0.8: all SQLite TEXT columns wrapped in Option<T>
- Integration tests: max_connections(1) on in-memory pool so all
connections share the same schema
All 191 tests pass; cargo clippy -D warnings clean.
