Public constructors and evaluators for GEPA candidate acceptance policies.

The built-in policies compare aggregate candidate scores. Custom callbacks receive the complete before/after result context and must return a documented accept or reject decision.

Summary

Types

callback()
callback_decision()
decision()
policy()

Functions

accept?(policy, before_result, after_result, context \\ %{})

Returns whether the policy accepts the proposed result.

callback(fun)

Builds a custom acceptance policy.

decide(policy, before_result, after_result, context \\ %{})

Evaluates a policy and returns its normalized decision and detail.

default(operation)

Returns the built-in policy for a mutation or merge.

Types

@type callback() :: (map() -> callback_decision())

callback_decision()

@type callback_decision() :: boolean() | decision() | {decision(), term()}

@type policy() :: :strict_improvement | :equal_or_better | {:callback, callback()}
