I read this as a read-only bytecode forensics task - I’ll extract the required metadata, search for an exact SHA match, then reproducibly reconstruct candidates only in `/tmp` if needed.


I read this as completed read-only bytecode recovery - I found and verified an exact reproducible reconstruction without touching the target.
