Session 57: Phase 0 — Kill the Lies (2309 tests)

Work-order Phase 0 (Jul 10 live audit): every fabricated UI element deleted
or rewired to real data. Deletion sprint — no new product features.

0.1 Fake NBA game: root cause was scheduleService fetching the ESPN
    scoreboard with no ?dates= param or date filter — off-season ESPN
    returns the NEAREST slate (Jun 13 NYK@SA Finals rendered as tonight).
    Now pinned to the requested ET date + defensive filter; undated events
    dropped. Honest month-aware per-sport empty states (lib/emptyState.js).
0.2 Fake header counters: liveTick stripped to a bare 1s pulse (the
    auto-incrementing "247 graded", sin-driven brain-%, aPlus/cascades are
    dead). New GET /api/snapshot/summary (cache-only, before /:sport) +
    Next proxy; HeartbeatBar shows the real graded count and SYNC =
    elapsed since the last pipeline run (amber past 5 min).
0.3 Ticker: hardcoded fallback items deleted (real snapshot exhaust only);
    MOVE kept — computeLineDeltas is real movement. <4 real items → no
    ticker; bar publishes --ticker-h so the fixed header collapses cleanly.
0.4 /terminal retired: route redirects to /dashboard; VVI/injury-wire/
    leaders layouts preserved unrouted as §12 content-engine templates.
    Nav PRIMARY = Slate/Scan/Ledger; BottomTabBar Terminal→Explore; PWA
    shortcut Terminal→Ledger; #terminal alias → /dashboard.
0.5 ›Query nav pill deleted (duplicate /scan link).

Backend 2289 → 2309 tests (199 suites), web build exit 0.
Spec: specs/phase-0-kill-the-lies.md. Next: work-order Phase 1 (ledger
persistence + settlement).
