C.28:4.13 - Cheap downgrade library

Case	Plain bounded result
association only	“The evidence supports an association report; it does not support an intervention-effect claim.”
temporal change only	“The change in time is recorded; a causal-effect claim remains unsupported.”
non-causal simulation	“The simulator produced these traces; no causal use is claimed.”
simulation used causally	“The validated model supports this bounded model-based comparison; it does not supply realized or interventional evidence.”
metric-only fairness	“The metric disparity is reported; causal fairness is not established.”
logged policy	“The evaluation supports only the named behaviour/evaluation-policy regime and overlap limits; unqualified optimality is unsupported.”
cross-rung benchmark	“The methods answer different causal questions; publish the bridge and its loss, report degraded parity, or abstain instead of naming one causal winner.”
