DISPLAY FIX (shipped): the league leaderboard rendered raw snake_case
("stolen_bases U0.5", "earned_runs U2.5"). New canonical short-label lib
web/src/lib/statAbbrev.js (one source, CommonJS + unit-tested) maps stat_type
to SB/ER/TB/HR/K/PTS/… and ExploreHub routes through it. Unknown ids upper-case
their words so raw snake_case can never leak again.
FLAG (reported, NOT silently changed — per the audit's instruction): the "B at
45% confidence" is a BACKEND grading issue, diagnosed against live snapshot:
- 25/25 grades mismatch their own confidence vs grade_thresholds.json (B shown
at conf 55 = the B- band; a systematic one-sub-tier gap on every prop). The
surfaced `confidence` is not the probability that derived the letter (likely
the data-sufficiency penalty applied to display-only).
- 9/25 have projection=0 — the MLB feature path feeds 0 instead of refusing
(S58 insufficient_data), which also produces the P1-7 broken edge_pct.
Full write-up + do-not list: specs/audit-data/mlb-grade-degradation.md. NOT
re-lettering or shifting thresholds on the frontend — that would hide the bug.

Phone audit: leaderboard flooded with 9 consecutive identical 'stolen_bases U0.5
45% B' rows. New shared lib/playerGrouping (dedupeLeaders + groupIntoLadders,
name-key aware, 7 unit tests): ONE row per (player, market family) keeping the
best-ranked, then a per-market cap (4) so no single prop type floods the board.
Applied to ExploreHub. Ledger cards + Consensus grouping follow in P0-3b/c using
the same lib.

Extend /explore (ExploreHub) into the 365-day never-dark hub. Two new
self-hiding sections feed REAL always-available data into the offseason:
- NewsWire (components/vyndr/NewsWire.tsx): real ESPN headlines from
/api/news/:sport (newest-first, mono timestamps, type chips, player/team
links) + real injuries from /api/schedule/:sport/injuries (OUT/GTD chips,
token colors). Reuses the retired TerminalTemplates INJURY_WIRE layout but
never routes its sample constants. Self-hides when both feeds are empty.
- FuturesBoard (components/vyndr/FuturesBoard.tsx): real futures from
/api/futures/:sport — championship/win-total/award markets, mono tabular
prices + movement colored by the contract (shortening=green / drifting=amber
/ flat=dim, NEVER red; move shown ONLY when the backend supplies one).
Carries the honest "TRACKED · NOT GRADED" label — no fabricated grades on
futures. Self-hides when markets:[].
- ExploreHub is offseason-aware (via emptyState OFF_SEASON month check): the
hub LEADS with futures + wire when the board is dark, COMPLEMENTS the live
board in-season. Sport selector kept; each section self-hides independently.
- Testable pure helpers: lib/futuresMove.js (move→color, never red) +
lib/newsFormat.js (timeAgo mono-stamp, ESPN type labels).
Contracts consumed (Wave 2A owns the proxy/service files); code self-hides on
fetch failure if a proxy isn't present yet.
Tests: tests/unit/newsWire.test.js + futuresBoard.test.js (26 new). Full suite
259 suites / 3144 green; web build exit 0. vyndrParityQA stays green
(mono data, no glitch on data surfaces).

- QA.20: one meaning per color, locked — STEAM amber (caution), VALUE
green (edge), red only at STALE/miss; revisions render the original
grade struck through on slate AND ledger.
- QA.21: every new data surface (PriorReads, PlayerStreaks, ModelRecord)
renders data in mono (tabular-nums via the .mono class).
- QA.22: waiting copy derives from the real cron schedule on every
surface (StatStrip, dashboard, Explore) — no passive mystery anywhere.
- Explore empty state joined the honest-waiting lib.
- Sweep result: no raw brand hexes and no sans-serif data in tonight's
components (sans only on prose/captions/hero letter — sanctioned);
glow confined to A-tier badges + reveal chrome; 390px containment
holds (wrapping chips, scroll-contained tables from Phase 3 rules).
Backend 2352 -> 2396 tests (205 suites), web build exit 0.

- StreaksPanel renders THE LENS (interpreted read + tonight difficulty) +
snapshot grade letters; streaks are FREE for every tier per the product
definition (the picture is free, the read is paid) — only hot lists keep
the free top-3 gate.
- One stat selection now filters ALL layers: card props narrow together
with streaks + hot lists (Slate activeStat → slateGameToCardData).
- /explore = server SEO shell (daily-indexable: 'MLB Hit Streaks, Hot
Hitters & Stat Leaders') + ExploreHub client: leaders + full streaks +
hot lists, real-tier gated, defaults to the in-season sport.
- Landing teaser fixed: it pointed at NBA (off-season → self-hid forever);
now MLB top-3 through the lens — the anonymous-visitor hook actually
shows.
- Player dossier: ACTIVE STREAKS block (free, lens reads) via new
?player= filter on /api/streaks/:sport.
- Schedule layer already the Slate base (mergeSlate) — verified, no change.
