Done. Summary of the run:

**Experiment**: Modular Memory Spectrum of Prime Gaps (11 bases, 41K gaps, 10 Cramer realizations)

**Finding**: The "140x algebraic channel" discovered on 2026-04-25 is a **mod-3 prohibition** — consecutive prime gaps cannot share the same non-zero residue mod 3. The mechanism is the shared middle prime p_{n+1}: it forces the walk on Z/3Z to invert before returning. Zero violations in 12,225 attempts. Cramer reproduces none of it (0% ordering).

**Key structural facts**:
- mod 6 memory (21.43%) = mod 3 memory (21.41%) exactly. F2 is mod-3 dressed in mod-6 clothing.
- Primorial hierarchy DILUTES: 21% → 9.8% → 9.1%. The dominant algebraic channel is at the smallest non-trivial prime.
- Prohibition strength follows 1/phi(p): mod 3 (50% forbidden), mod 5 (25%), mod 7 (17%).
- The 21.4% is analytically predicted from the transition matrix with hard zeros.

**Consecutio**: Does the same prohibition exist in other sieve-structured sequences (squarefree numbers, k-smooth numbers)?
