Model GDB console completion, use real directory reads and cleanup for late-enumeration failures, and distinguish supported PTX pointer qualifiers from unknown declarations. Preserve original assertion and cleanup failures through scoped test finalizers.
Continue validating child directories observed before a parent enumeration failure. Reconcile unobserved link targets at the reader using canonical path identity and the nearest failed ancestor, preserving exclusions and cancellation.
