Strategy Arena

The beta competition surface where private strategy candidates are simulated, evaluated, and compared under fixed rules.

Strategy family

A bounded product domain with its own lifecycle and parameter model. The current implemented public family is strategy-arena.

Epoch

A fixed evaluation period with a shared market universe, datasets, benchmarks, costs, and gates.

Benchmark Hold

The plain control strategy used as the benchmark utility denominator for beta scoring.

Beta score

The current public leaderboard value returned as evaluation.data.score.

CapitalScore

A robustness diagnostic that penalizes utility variance and small samples.

ContestScore

A contest reward and duplicate-aware participation score. It is independent from capital allocation logic.

Eligibility

A gate result that says a strategy passed configured checks. It is not a capital commitment.

Reproducible artifact

A manifest, report, hash, or metadata bundle that helps another reader replay or audit an outcome.

Guarded vault

A future capital path where vault rules constrain assets, size, risk, execution, and operations.

Confidential compute

Provider-neutral private evaluation infrastructure used to protect sensitive strategy inputs during submission and evaluation.

Public settlement

The principle that final market effects can be public even when strategy inputs and pre-selection decisioning were protected.
