/**
 * Known scorer names for the NGT (Agentforce Studio) test runner — used for IDE
 * autocomplete and the per-scorer metadata in {@link NgtScorerCatalog}.
 *
 * The `(string & NonNullable<unknown>)` branch keeps this open: arbitrary names from a future Core
 * release pass type-checks. Validation is non-strict on purpose — `validateNgtSpec`
 * emits a lifecycle warning for unknown names, and Core's MD validator
 * (`AITestingOOTBEvaluations.resolveByKeyOrName`) is the authoritative runtime gate.
 *
 * Update when Core ships a new OOTB scorer.
 *
 * Future direction: when `AiTestingDefinition` lands in `@salesforce/types`
 * (currently only `AiEvaluationDefinition` is published; see forcedotcom/wsdl
 * `src/metadata.ts`), the XML types should be swapped for generated ones. The
 * scorer name list itself isn't enum-typed in the WSDL though, so this catalog
 * stays the source of truth for the `needsExpected` and `grade` metadata even
 * after that swap.
