fix(kalshi-res): watchlist filter + event category cache - #1691
Merged
Conversation
…ache
- pollFinalized now fetches category from /events/{event_ticker} (cached)
- Exotics (KXMV* multivariate parlays) excluded: settle algorithmically
in 0-200s, not comparable to prediction market questions
- Category mapping: Sports->sports, Politics/Elections->politics,
Crypto/Financials->crypto, rest->other
- settlement_ts used for exact delay (not poll-time proxy)
- Bench YAML methodology + disclaimer updated with anchor asymmetry note
…ed natural filter

Replaces the Exotics-via-category-API approach with a cleaner structural fix.
Root cause insight: Exotics (auto-generated multivariate parlays) auto-settle so fast they skip the
status=closedstate entirely — they go open→finalized in seconds. ThepollClosed()endpoint (status=closed) therefore never returns them, so thewatchedmap is naturally Exotics-free.Fix:
pollFinalized()now only emits for markets inwatched. Markets not in the watchlist (Exotics + any market outside the lookback window) are markedrecordedand skipped. No explicit category filter needed.Category: still fetched from
/events/{event_ticker}(lazy cache) for proper labeling. Category mapping: Sports→sports, Politics/Elections→politics, Crypto/Financials→crypto, rest→other.Tradeoff: no 30-day historical backfill for Kalshi (can't know which historical markets went through "closed" before harness started). Data accumulates going forward. Polymarket still gets its 7-day on-chain backfill.
Bench YAML methodology note updated accordingly.
