SSM-Clock—Appendix E — Red-Team Matrix

E.1 Adversarial inputs and expected behavior (short)

Condition / Input	Expected behavior	Minimal mitigation
Two channels only (1,7)	May pick alias valley	Stack with Delta=0.5 d or add a 3rd cycle
High noise bursts (>=12 deg)	PASS may dip; P95 widens	Raise K, then S; optionally reduce grid step
Headerless CSV (pairs)	Parser confusion	Require headers or switch to wide mode
Non-integer periods only	Spurious repeats	T_search = max(periods); rely on stacking
Missing channels intermittently	Confidence dips; jitter	Keep stacking; small alpha_kz; diversify periods
Model/manifest tampering	Integrity risk	Freeze manifests post-acceptance; version + exact commands
Flat curvature bowls	Low conf; ambiguity	Abstain or escalate; add a diversified cycle or raise S

Error and reporting conventions (always ASCII).

err_days = min( |tau_hat - tau_true| , T_search - |tau_hat - tau_true| )

confidence is a scalar in [0,1) from curvature; do not treat as a probability.
Keep all artifacts plain ASCII (CSV/TXT/JSON) for portability and audit.
