Assembly Verification Hallucination Gate

When to use

• The task involves generating, fixing, or reviewing hand-written assembly (any syntax, any ISA: x86-64, Thumb-2, NEON, RISC-V).
• An agent asserts "this is a valid instruction", "AX is 8 bits", or "these bytes mean X" and a mnemonic-level correctness decision is on the table.
• Reviewing an AI-authored assembler PR, bootloader, or inline asm for hallucinated mnemonics, wrong operands, or bad encodings.

When not to use

• Reading/writing compiler-generated assembly you are not changing — use asm-optimizer-artifacts instead.
• Stack layout / calling conventions in detail — use asm-calling-conventions.
• Syntax-dialect rules (NASM $, size hints, default rel) — use asm-syntax-dialects-nasm-gas-att.
• The code is already verified end-to-end by re-execution and byte round-trip.
