Reuse the positional range owner for target metadata, Hopper Mach-O selection and Kuna spans. Preserve physical failures, completed span evidence and cleanup ownership across cancellation and short reads.
Validated 147 focused file and lifecycle tests; ten new cases reproduced failures against the prior implementation.
Continue reading Mach-O and Electron ranges after positive short descriptor reads, while preserving explicit EOF, cancellation, file identity and cleanup semantics. Advance fuse scanning and hashing by the bytes actually read.
Validated focused filesystem, Mach-O, dyld, Electron and MCP workflows: 117 tests passed, two Windows-only tests skipped; check:fast passed.
