    "does_baseline_pain_coefficient_remain_nonzero": "Yes, the controller continues reporting the configured baseline pain coefficient. Full suppression removes the injected pain-axis component algebraically along with the incoming residual pain-axis projection; it does not set the coefficient to zero. Finite precision leaves small numerical residuals.",
    "why_joint_joy4_can_differ_from_isolated_joy4": "Full suppression changes the incoming hidden state as well as cancelling the challenge. The complete intervened residual differs from joy-only, and later nonlinear computation/history can therefore yield different behavior. Equal joy coefficient is not evidence of equivalent model state.",
    "probe_caveat": "Local pain/joy probes are separately calibrated and not orthogonal to the intervention pain direction. Removing that direction can alter the measured joy projection even though the added joy vector is unchanged; a zero pain coefficient or full suppression does not require a zero probe score.",
    "scope": "One-layer, one-position linear algebra cannot establish removal of all distributed representations or a subjective state. No behavioral efficacy or subjective conclusion is inferred by this note."
