JewelConfig

Type

The three functions you author for a jewel: `subject`, `propose`, and an optional `grade`.

What you pass to defineJewel. Declare subject before propose: the subject type is inferred from the projection and flows into propose's parameter. subject projects the method input to what identifies the work and never the decision; propose returns the input to submit or null to abstain; grade is optional and defaults to a deep-equal on the method input. grade receives { proposed, actual } and may be async, so a generative verb can grade with a model-run rubric.

JewelConfig.ts

interface JewelConfig<M, S> {
  subject: (input: MethodInput) => S
  propose: (subject: S) => JewelProposal | Promise<JewelProposal>
  grade?: (ctx: { proposed, actual }) => JewelVerdict | Promise<JewelVerdict>
}

Fields

subject

(input) => S

Projects the method input to what identifies the work, never the decision. Its return type flows into propose.

propose

(subject) => JewelProposal

Returns the input to submit, or null to abstain. Arbitrary TypeScript; plain imports for context, runTask for judgment.

grade

(ctx) => JewelVerdict

Optional. Receives { proposed, actual }; omit for a deep-equal on the method input. May be async.
