Two knobs are silently misreadable:constant.cost_per_tradeis a price-unit numerator charged ascost / |entry − stop|in R. This is currently stated only inaura run --helpunder the r-sma-only cost flags — a different verb than the one a campaign author uses. The natural misreading (a cost in R) is wrong by orders of magnitude and produces no error.vol{length, k}:stop = k · Sqrt(EMA(Δ², length))over m1 cycles —lengthsmooths the estimator,kscales the distance. Stated nowhere outsidecrates/aura-std/src/stop_rule.rs; the natural misreading (lengthas the stop's timescale) changes an experiment's meaning without an error.A one-line unit/semantics annotation per knob in the
campaign introspectoutput, mirrored in the glossary cost-model and risk-regime entries, removes both.
