Plan and validate every internal ZIP, Zip4j, and SevenZipJBinding entry and final conflict target before any archive output mutates the filesystem. Preserve raw RAR list entry whitespace for strict validation and keep any non-matching package owner marker immutable while direct scoped outputs continue without marker reissuance.
Reject alternate data streams, reserved Win32 device names, and trailing-dot or trailing-space aliases before internal ZIP, JVM, or native extraction writes. Preflight native archive entry lists, reconcile opened JVM outputs to partial or removed state on abnormal results, and replace hardlink-based owner markers with portable exclusive reservation plus atomic replacement while allowing direct scoped extraction to continue when marker persistence is unavailable.
Reject symlink and reparse boundaries before internal ZIP or JVM outputs are opened, track opened, committed, partial, removed output lifecycle events, and convert output callback failures into controlled extractor failures without poisoning the JVM daemon. Gate legacy recovery behind an atomically created package-generation owner marker and keep unmarked reused or shared directories fail closed. Parse native RAR output from strictly verified locale-independent candidates while retaining ambiguous rename rejection.
Remove .rd-output staging and merge handling, parse validated native extractor output, and drive nested extraction, rename, audio, cleanup, residual handling, and library collection from package-owned output records. Preserve provenance migration, package pruning, and run-owned waiter isolation while allowing one bounded legacy adoption scan only for provably exclusive package roots.
Replace package staging assumptions with validated per-generation output records for internal ZIP and both JVM backends. Persist resume v2 using relative archive identities, complete member fingerprints, and concrete verified outputs so basename collisions, changed members, missing outputs, and unknown versions fail closed.
