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.
Fixes#3574Fixes#5188
Normalize path facts once at the owning filesystem boundary, preserve caller spelling and unavailable inventory members, and retain typed read failures. Record exclusion entry kinds so only proven directories can establish descendant symlink targets; omitted legacy kinds stay unknown.
Reviewed fixes include #1969, #2642, #2759, and #2994.
Validation: 26 reference graph source tests passed; prior artifact checks passed 275 tests with one Windows-only skip. Updated compiled import workflows are included in final validation after regeneration.
