Capture exact filesystem identity and nanosecond timestamps, validate descriptor/path state before and after streaming, and enforce the captured byte count. Bound growing files to their captured size plus one byte using precise positional reads; keep unrepresentable display sizes explicitly unknown. Reuse the captured-state comparison around Apple assetutil and retain existing reader cleanup ownership. Validation: focused reader and affected consumer suites, full static/architecture checks, and a compiled directory-read probe on Bun 1.3.14 passed. Includes same-size mutation, growth, truncation, cancellation, FIFO replacement, cleanup retry, ZIP identity forgery, ASAR and Mach-O coverage.
