Route full, hybrid, top-level nested, and deferred nested archive work through the single global coordinator and remove the package-level extraction slot layer. Build each operation reservation from deduplicated multipart members, retain it through real child close and package output-scope finalization, and preserve package/run cancellation ownership while clearing queued waiters. Delay native and JVM abort/timeout completion until child close, retain daemon requests until exit, drain extraction before session persistence, and stop the daemon last. Add focused integration, process lifecycle, lease, and shutdown ordering regression coverage.
Add a fair operation-aware queue that owns the global archive child limit across packages and extraction modes. Support live resizing, immutable operation identity, selective run and package cancellation, ghost-waiter cleanup, idempotent permits, deduplicated multipart disk reservations, held operation leases, and deadline-bounded shutdown draining. Cover peak concurrency, fairness, resize, cancellation, multi-batch drain renewal, terminal lease paths, multipart accounting, and shutdown ordering with focused RED-to-GREEN tests.
