    Variable MAX_PATH_ITEM_REF_HOPSConst

    MAX_PATH_ITEM_REF_HOPS: 8

    Maximum number of $ref hops permitted when walking a chain of OpenAPI Path Item Object references. Beyond this a path-item-ref-too-deep diagnostic is emitted and resolution stops.

    Also the default maxHops for the generic resolveRefChain helper in core/refChain.ts, so every ref-chain walker — Path Item refs, Parameter / Response refs, Reference Object chains, etc. — shares the same hop cap.
