What problem does it solve? Building a betting feature for a new championship (golf, Rocket League, LoL) from scratch is error-prone: odds can be tampered client-side, correlated markets can be combined into +EV accumulators, and settlement can double-pay. This Skill encodes a proven, reusable pattern for betting cards in the Primitivão app, including anti-exploit guards already validated in the MK championship. ## Core Features & Use Cases - Standardized data model: Defines Leg and Ticket structures with prefixed fixtureIds and champId-scoped bet rankings, so settlement and summaries work consistently across championships. - Server-side odds recomputation: placeBet re-derives odds/probability from remote state, rejects closed or started markets, and enforces singles-only slips for correlated markets. - Idempotent settlement: A result-keyed effect settles pending tickets from real results, pays payouts in the same transaction, and ports copy-bet economics (insurance, deferred cashback, follow fees). - Use Case: When adding betting to a new golf championship, follow the 9-step checklist to define markets, build the card UI branch in the APOSTAS tab, wire the slip and placeBet, add locks and settlement, then run an adversarial money review before deploy. ## Quick Start Ask the AI to create a betting card for a new championship following the card-de-apostas pattern, including markets, odds, slip, placeBet, settlement, and anti-exploit locks.
