Keep raw physical read diagnostics alongside explicit operation provenance on the same cleanup owner. Preserve provenance after successful close retry for opted-in readers, restore legacy error projections, and prevent borrowed cleanup-shaped failures from authorizing foreign resource retries.
Refs #5686
Do not interpret exact caller cancellation reasons as descriptor ownership records. Preserve checkpoint-shaped reasons through successful close retry and supply cancellation context in direct signal-aware cleanup consumers.
Validation: 156 focused tests across 14 files passed; no native provider execution. Refs #4610
Record cancellation at file checkpoints and before owner handoff. Keep physical hash failures, exact reasons, completed facts and failed-close owners distinct through artifact and provider projections and cleanup retries.
Refs #4598. Validated with 566 passing affected tests and 22 platform skips; final Kuna cleanup reason rerun passed 43 tests. No Android device or real JADX/Kuna execution claimed.
Fixes#4379.
Observe cancellation after file metadata, verified descriptor closure and recovered scope cleanup. Retain completed physical read outcomes and acquired-file digests under cancellation; preserve original failures and exact cleanup owners when close fails.
Bind cancellation markers to their verified owner so raw readers preserve nested callback outcomes and exact caller reasons. Reuse one ADB partial-result mapper for file, package and bugreport acquisition.
Validated with 570 related tests, source/docs checks, real Linux filesystem cancellation/cleanup/nesting probes and actual public CLI/MCP Evidence workflows.
