Return the validated descriptor and its original metadata from regular-file
admission. Propagate that contract through owned reads, hashes, snapshots,
artifact inventory and provider file workflows instead of replacing initial
facts with another stat. Keep arbitrary output-handle operations separate.
Preserve final descriptor/path identity proofs, borrowed-source verification,
BigInt precision, cancellation provenance and failed-close ownership. Remove
the obsolete source and owned-ZIP baseline stages and update their consumers
and regressions. Tie read completion faults to actual reads instead of the
retired duplicate stat; instrument real handles without fake handle wrappers.
Validation: fresh runtime/catalog build; focused source, lifecycle, filesystem,
CLI/MCP and authored provider-fixture tests; full static checks; docs checks;
test discovery; duplication check. Platform-specific cases remain skipped on
macOS. No installed provider or device behavior was verified.
Classify selected-input read failures at the shared artifact boundary and remove duplicate phase-based translations from TShark and sigrok. Keep other read stages raw for their existing owners and retain cleanup resources until retry succeeds.
Extend the descriptor outcome matrix with post-run private-copy integrity failures, late cancellation, retained command output, failed cleanup, and successful retry.
Classify canonical physical file outcomes through the provider mapper before composing cleanup. Retain unknown capabilities as unresolved and replace runtime failure maps with exact leases, including mixed cleanup and partial retry.
Keep completed-read cancellation output and cleanup history. Closes#4865.
Validation: 179 unique focused tests passed across 13 selected files, 7 Linux-only skips; static checks, docs checks and 1551-file discovery passed. Authored Node producers and controlled real-descriptor faults do not qualify native providers.
