4.1 ROOT CAUSE of 'Ohtani returns nothing': no backend
/api/players/search existed (MLB 404'd; NBA/WNBA hit the offline
Python service). New Express route + mlbStatsAdapter.matchPlayers —
canonical nameKey fuzzy match (exact > last-name prefix > folded
substring). LIVE-VERIFIED vs the real 1,299-player list: Ohtani /
Aaron Judge / Sánchez / sanchez / Chisholm Jr all resolve; accented
and unaccented return identical results. Non-MLB matches the
platform's cached names (rosterlogs + grades), cache-only.
4.2 Reveal choreography per §7: analyzing steps → DECLASSIFIED stamp →
90ms-staggered context panels (entrance floors visible per the
Phase-0 rule); prefers-reduced-motion skips straight to the card.
4.3 PRIOR READS chips on scan results — the model's public ledger
history for the player (deferred-render, outcomes + pending, never
invented). /api/ledger/model gains ?player= on entries.
4.4 Parlay Lab: humanized stat labels via the ONE shared formatter
(lib/gradeAdapter.statLabel); 1-leg provisional grade ('Leg grade:
B — add a leg for the combined read'); discoverable entry — Nav
'Parlay Lab' item opens the drawer via window.__openParlay, and the
open drawer now renders an honest empty state at 0 legs.

Overnight sprint for the Saturday 10 AM ET deploy gate — day one of the
public ledger record locks against freshly posted lines.
Task A — ledger team/opponent (migration 020, applied at 0 rows):
populated in both write paths from the real feed; opponent only when the
player's team matches a game participant (never guessed). Roadmap: Phase
4.5 WNBA ESPN-boxscore settlement (due ~Jul 24) + Phase 5 per-tier
calibration logged.
Task B — work-order 1.6 CLOSED (canonical player keys):
- searchPlayer resolves via nameKey; the old matcher deleted accents
("Sanchez" with acute -> "snchez") and substring-guessed onto the WRONG
player (the mismatched last-10 bug). Ambiguous -> null, never guess.
- Slate JOIN INVARIANT: a graded prop whose player's real team isn't in
the game is dropped (TB player can't render under MIL@PIT) — locked by
tests that fail the suite on regression.
- grades:{sport} TTL 2h -> 6h (expired between 5h cron gaps — the real
cause of /team "No active props" for slate players).
Task C — Phase 2 slate UX: tabs are THE filter (URL ?sport=, deep-linkable,
duplicate legacy tablist removed); cards cap at 6 graded props sorted
A+->F with ALL N READS in-place expander; waiting states show the real
next pipeline run ("Grades post ~6:00 PM ET").
Task D — Phase 3 mobile P0: root cause of vanished 390px nav was HIDE_ON
including '/' (landing had zero navigation) — fixed; html/body overflow-x
contained; GAME LINES collapses to best-line summary + "N BOOKS" expander
below 640px; venue drops before time/pitchers ever truncate.
Live verification: raw ESPN today STILL returns the Jun 13 NYK@SA Finals
game without a date pin; the pinned fetch returns 0 games, 0 off-date.
Backend 2327 -> 2352 tests (202 suites), web build exit 0.
