	#!/usr/bin/env bash
	#
	# Detector for the crates.io supply-chain attack of 2026-08-20 (arrayref / proc-macro1).
	#
	# The payload is a build-time dependency: compiling a project that resolved to an affected
	# version is enough to be infected. This script is READ-ONLY -- it reports and exits with a
	# status code, it never removes or modifies anything.
	#
	# Exit codes: 0 clean, 1 suspect (manual review), 2 confirmed, 3 script/environment error.

	## Core Principles

	- Surface tradeoffs explicitly.
	- Never hide uncertainty or confusion.
	- Be concrete. Use real examples and exact failure modes.
	- Verify behavior empirically whenever possible.
