failed to read %s from zip: %w

Error message

failed to read %s from zip: %w

What it means

extractBinaryFromZip scans the SBOM scanner tool's zip archive for the scanner binary and streams it out. This error wraps an io.Read failure on the matched zip entry — the archive entry exists and opened, but its decompressed bytes could not be read (truncated/corrupt archive, I/O error). The wrapped cause identifies the underlying problem; re-download or replace the scanner zip.
