SHIP-READY — FAIRLINE /events: Sport Tabs (NBA default) + Watchlist Pins

Date: 2026-02-24

Outcome

Upgraded /events to be daily-usable by adding a primary Sport Router (NBA default) and a persistent Watchlist (pin/unpin) workflow, plus surfaced-card operator essentials (freshness + books aligned) shown directly on the cards.

This remains decision-support only; no scan math, joins, or API behavior changed.

What changed

Sport Router (primary control)

• New top section: SPORT FOCUS tabs:
  • NBA (default)
  • CBB
  • Soccer (bundle: EPL + UCL)
  • MMA
  • All
• Uses existing cfg.sportKeys semantics:
  • [] = All sports
  • persisted via fairline:boardCfg

Watchlist (pins)

• Added persistent Watchlist section (localStorage fairline:watchlist).
• Pins can be added from Surfaced cards via + Pin.
• Watchlist items show:
  • Passing status (still on board vs not)
  • Quick Intel CTA
  • Unpin

Surfaced cards: operator essentials

• Surfaced cards now display freshness (age median/min) and books aligned directly (not buried in tags).
