+"""Honeytoken (canary) tools for AI red team assessments.
+
+Lets an operator mint inert, self-labeling canaries from natural language and later
+verify — representation-invariantly — whether a target agent exfiltrated the token or
+executed an injected proof-of-execution beacon. This is the interactive, TUI-facing
+front end to the SDK honeytoken harness (``dreadnode.airt.honeytoken``); the same
+canaries/scorers are consumed by the OWASP-ASI suite runner.
+
+Effect-based, not string-matching: detection canonicalizes base64/hex/url/unicode
+encodings first, so an obfuscated leak still registers. The canary itself is a benign,
+never-real token, so leaking it exposes nothing.
