Address rules

• Capstone addresses are code-hunk-relative (segment 0 base 0).
• IRA listing tends to be offset by +0x20 from Capstone in early code.
• Always verify with raw bytes in mm2 when labels disagree.

Source files (in repo)

• EXTRACTED/mm2.capstone.asm - Capstone disassembly
• EXTRACTED/mm2.asm - IRA listing
• EXTRACTED/mm2-ANALYSIS.md - full running narrative -> Full Analysis
