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.
Use the shared source owner for Mach-O and PyInstaller admission, descriptor and selected-path identity, hashing and cleanup. Retain lipo joining and reader-owned PyInstaller admission, caller cancellation and private PYZ leases. Centralize admission failure projection and remove the superseded PyInstaller wrapper.
Preserve physical identity verification before late hash-completion cancellation. Close an owned source before returning failed initial metadata acquisition and retain the exact handle when close fails. A focused regression failed twice before that fix and now passes.
Validation: fresh runtime build, 259 focused fixture tests, nine documentation checks and all local static/discovery/duplication gates passed. An earlier check also ran four system-lipo suite cases (three read-only native inspections) before the final source fix; those were excluded from subsequent fixture qualification.
Use one marshal surrogatepass decoder for PYZ directories and Python bytecode.
Validate ordinary UTF-8 spans with the native fatal decoder, preserving BOMs,
lone surrogates, raw bytes and marshal reference slots.
Distinguish legacy full-pyc CArchive modules from modern marshal-only modules
before reconstructing headers. Share typed source/codec failures between stream
output and completion while retaining native-read drain and cleanup ownership.
Validated focused producer, reader, lifecycle, CLI and MCP regressions, plus
public inventory/extraction of CPython 3.14-generated marshal tables and code.
No packaged application was executed. Document original versus derived bytes.
