5 YAMLs for the canary-fingerprint cohort per Appendix B / A.9: navigator.webdriver flag, automation canvas/audio/WebGL hash match, WebRTC IP leak, TZ/lang vs geo mismatch, platform inconsistency. CanaryFingerprintLifter (E.3.11) consumes by rule_id. test_canary_rules.py: YAML-present + inert-in-v0 + xfail(strict) gated on E.3.11.

"""R0049-R0053 — canary fingerprint cohort.

CanaryFingerprintLifter (E.3.11) parses the fingerprint payload

(navigator/webdriver flag, canvas/audio/WebGL hashes, WebRTC IPs,

TZ/language/geo composite) and emits per Appendix A.9. The v0

:class:`RuleEngine` cannot navigate a structured fingerprint blob —

these rules are inert under the regex matcher.
