Done. Summary of this run:

**Experiment**: Two-Channel Boundary Separation — do the residue and magnitude channels of prime gaps lose structure at the same scale?

**Finding**: No. The two channels have **opposite boundary behaviors**:
- **Residue/mod-3 channel** (algebraic): z-scores of 26-44σ across the entire range (23K to 4.5M primes). Decay correlation with ln(p) = -0.19. **No boundary.** Scale-invariant.
- **Magnitude channel** (statistical): z-scores of 2-7σ, decay correlation +0.46. **Has a boundary**, slowly approaching Poisson.
- The **r-statistic** mixes both, showing a "crossover" that is actually the magnitude channel decaying while the algebraic channel stays invariant.

**Verdict**: NEW + CONSTRAINT on BOUNDARY, META, DUALITA_DIPOLARE_VS_ILLUSORIA

**Files**: `exp_two_channel_boundary.py` (reusable tool), `two_channel_boundary.json` (data), `reports/agent_20260429_0833.md` (report). Seme updated with constraints on BOUNDARY and META.
