Campaign 28 audits whether residual Selberg symmetry or a simple two-scale signed recurrence can coerce the Lambda-Lambda-sharp primitive against a persistent polynomial/Mellin drift.

Main results:
- residual Selberg symmetry is derived from the classical Selberg remainder formula plus the bounded primitive of Lambda-sharp;
- for every fixed Mellin mode x^rho with Re rho<1, the positive Lambda-sharp sampling channel produces a 1/log x contribution, exactly within the classical forcing scale;
- therefore fixed-order Selberg feedback does not produce a fixed polynomial drift gap;
- residual PESC remains energy-locked: C_f=(J_f-D_f)/2, and smooth drift gives C_f~J_f/2;
- a uniform fixed two-scale contraction of normalized residual energy already has fixed-zero-strip strength;
- no lower-strength drift coercivity theorem is found;
- Campaign 29 tests higher-order generalized Selberg filters and growing order.

No proof or disproof of RH is claimed.
