Change contract
Add one research-only CEX time-series HFT alpha-discovery adapter to the existing shared UCT/MCTS kernel. It must run a frozen replay snapshot through a CEX-specific evaluator and use post-cost training reward; the selected candidate alone receives held-out evaluation.
Acceptance evidence
- A versioned immutable CEX snapshot contract identifies venue, symbol, instrument type, sampling/replay clock, dataset range, L2/order-book and trade-tape artifact hashes, and feature availability times.
- The evaluator rejects incomplete, out-of-order, or look-ahead data; it models the declared fill assumptions, latency, fees/rebates, spread, liquidity consumption, and slippage.
- Training reward is derived only from purged/event-disjoint or time-disjoint training windows; held-out evidence cannot backpropagate.
- The shared UCT kernel and durable checkpoint/recovery are reused; no second MCTS implementation.
- Focused counterexample tests prove snapshot-identity rejection, time-order/look-ahead rejection, and held-out isolation.
Out of scope
Live execution, exchange credentials, order routing, deployment, market-making inventory policy, and changes to the Polymarket evaluator or PR #204.
Dependency / merge order
Depends on the merged shared MCTS kernel and runner chain (#190, #195, #199, #200, #201). It is independent of Polymarket checkpoint-artifact publication (#202 / PR #204).
Rollout / rollback
Research-only and fail-closed. A single CEX adapter PR can be reverted without changing the UCT kernel or Polymarket research path.
