How to use this

1. Scaffold (tools/decompile.py <fn> or Ghidra MCP), then consult the entries below to shape the C toward the target idioms before iterating asm-differ — it saves rounds.
2. When you discover a new asm↔C correspondence or a "what makes gcc emit X" trick, add it here.
3. When a residual diff is pure instruction scheduling (provably-independent ops reordered), that's a decomp-permuter job, not a hand-iteration job — note it and move on.
