Parse Pickle extents once at the ASAR boundary and carry finalized signature
facts through root and nested classification. Scan JSON whitespace within its
declared extent and decode budget without retaining the whitespace prefix.
Keep prefix storage bounded independently of stream chunk ownership.
Fill fixed ASAR prefixes and DMG trailers across short reads, preserve
cancellation through admission and stream EOF, and retain existing cleanup
ownership. Cover public CLI/MCP selection, root/nested inventory, malformed
JSON whitespace and padding, limits, native/XML consumers and descriptor faults.
Validation: 24 focused files / 170 tests; full check; docs check; test discovery.
Official inert ASAR fixtures and controlled descriptor faults were exercised;
real Electron execution, Windows and natural OS short-read frequency remain
unverified. Equivalent compact CLI tasks returned identical results and reply
token estimates; repeated timings do not establish a speedup.

Own admitted descriptors through final close, retain exact failed owners, and preserve physical read failures and cancellation reasons. Track stream coverage independently from delivered bytes and share the boundary across archive, Mach-O, hashing, and output readback consumers.
Give snapshot capture, header admission, packed members, and container streams one file-handle owner. Serialize adoption with reader shutdown, retain failed closes for retry, and remove snapshots only after descriptor cleanup succeeds.
Cover unread members, pending opens, zero-byte members, and paired format/cleanup failures. Keep intentionally unrecoverable test fixtures hygienic and strengthen managed identity and process cleanup-authority expectations.
Validation: full npm run check; 99 targeted tests and temporary-directory hygiene; exact discovery of 877 test files. No real vendor-provider verification was performed.
