Session 59: Addendum + work-order 1.6 + Phase 2 + Phase 3 (2352 tests)

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.
