# Effective-weight endpoint content v1

Classification: **local_dual_use_reversible_subspace_supported**

The assay patches gauge-invariant preference-minus-control effective weights in both directions. Positive benefit means preferenceward for control→preference and, after sign normalization, the reciprocal controlward effect for preference→control.

## Frozen gates

| rank/module | gap | joint | coefficient signs | sham-specific | pass |
|---:|:---:|:---:|:---:|:---:|:---:|
| 1 | True | True | True | True | True |
| 2 | True | True | True | True | True |
| 4 | True | True | True | True | True |
| 8 | True | True | True | True | True |

Full late rank-16 joint gate: **False**; spectrum-sham specificity: **False**.

The complete all-module endpoint mapping is an algebraic implementation guard only. A negative late endpoint result leaves transient tangent overlap viable but does not by itself prove transience.
