Use when triaging an unknown binary, decompiling with Ghidra, scripting radare2, or diffing two builds for patched functions. Not for ELF structure basics: use elf-inspection.

# Reverse engineering

## Contract

| Field | Bound contract |
|---|---|
| Trigger | A user must understand a binary without source: triage an unknown file, recover logic with a decompiler, script an analysis, identify C++ patterns or the entry point in a stripped binary, patch a copy, or find which functions changed between two builds. |
| Authority | Reversible local: writes only analysis notes, scripts, and patched binary copies under a scratch directory named in the report; rollback is deleting that directory. The original binary is never modified in place. No remote mutation. |
| Side effect | Runs triage and analysis tools on copies of the binary and records findings. |
| Done | Each question about the binary is answered with the tool output as evidence: the file type, the protections, the decompiled region or disassembly, and, for diffs, the list of changed functions. |

## Inputs

1. The binary (required): a path to the file. Work on a copy in a scratch directory. Untrusted binaries are analyzed in an isolated lab machine or VM, never on a workstation with credentials.
