| "frozen_at": "2026-09-02T11:49:56Z", |
| "status": "frozen-before-any-amended-control-output", |
| "scope": "Random-direction controls only; the cohort, layers, fitted physical directions, primary interventions, endpoints, and inference procedures are unchanged.", |
| "reason": "Isotropic Gaussian directions produced severe nonspecific output-distribution disruption in the 12B audit and therefore did not provide activation-manifold-matched controls.", |
| "construction": { |
| "source": "The same independent development states used to fit the frozen physical direction.", |
| "paired_differences": "For each matched development pair, subtract the unit-normalized negative-outcome state from the unit-normalized positive-outcome state.", |
| "null_axes": "For each prespecified seed, apply a balanced random sign permutation to the paired differences, average them, remove the physical-direction component and components along earlier control axes, and unit-normalize.", |
| "seeds": [1701, 1702, 1703], |
| "orientations": ["plus", "minus"], |
| "distance_matching": "For every target prompt and operation, both orientations receive exactly the L2 length of the corresponding physical-coordinate perturbation.", |
| "summary": "Average the six oriented controls (three axes times two orientations) within prompt before law-level inference. Antithetic orientations cancel first-order arbitrary-axis effects while retaining nonlinear or generic disruption." |
| }, |
| "audit_policy": "The superseded Gaussian-control rows are retained in explicitly labeled debug directories and excluded from confirmatory summaries.", |
| "interpretation_guardrail": "A positive result supports a selective contribution of the tested coordinate, not unique necessity of a complete physical representation." |
