- gradeSlateService writes grades:{sport} cache (closes content pipeline →
dataLevel full); fire-and-forget from oddsService.recordDownstream, gated
by shouldGradeSlate (off in test, GRADE_SLATE_ON_FETCH override)
- NFL/NHL wired: oddsService SPORT_KEYS/SPORT_MARKETS (correct the-odds-api
keys americanfootball_nfl/icehockey_nhl), proplineAdapter MARKETS, NHL
MARKET_MAP keys to avoid silent-zero
- rate limiting mounted on 8 public cached routers (odds/parlay 30/min,
rest 60/min)
- jsonlLogger writes to temp under test (no more dirtied tracked artifact);
5MB pipeline test given 20s timeout
