Wave 0 shipped NBA/WNBA grading off ESPN per-athlete gamelogs, but name→id
resolution went only through the v2 /search endpoint, which is unreliable at
the edges. Live probing surfaced the real coverage gap: search actually
resolves the right id for most names, but dual-league athletes (WNBA + NCAA —
e.g. Napheesa Collier, Brionna Jones) get a filters-only gamelog until a
`?season=` is supplied, so they silently returned insufficient_data despite a
full season of games.
Two fixes:
1. buildAthleteRosterIndex(sport) — aggregates every team roster for nba/wnba
into a complete { nameKey → {id, displayName, teamId} } map (canonical
accent-folded keys via playerName.nameKey). Bounded concurrency (6) over the
~15-30 team fetches, Redis `espnroster:{sport}` (24h) + in-memory mirror,
fully defensive (a failing team is skipped → partial index, never throws;
grouped OR flat athletes[] shapes handled; non-numeric ids dropped). This is
now the PRIMARY resolver in resolveAthleteId/getPlayerGameLog; the v2 search
stays as a backstop on a roster miss. A unique roster hit wins (S59 doctrine)
— a missing name beats guessing another player's id.
2. getPlayerGameLog retries the gamelog with candidate seasons (current +
previous calendar year) ONLY when the first parse comes back empty
(filters-only), unlocking the dual-league athletes. The common path is
untouched.
MLB path (statsapi) unchanged; settlement/snapshot/frontend untouched.
Live probe: WNBA roster index = 206 players (Collier id 3917450 / Lynx team 8,
Brionna Jones id 3058895 present); NBA index = 544. Collier now resolves
end-to-end with 20 gamelog rows (was NOT FOUND); Brionna Jones likewise; all
previously-working players (A'ja Wilson, Ionescu, Clark, Stewart, Plum) still
resolve. NBA hyphen names (Gilgeous-Alexander) resolve via nameKey folding.
Tests: tests/unit/espnRosterIndex.test.js (9, fail-then-pass on base adapter).
Full backend suite 3183 green; web build exit 0.
