""" brownian_closures.py — the ZFA closures of a Brownian phase, computed EXACTLY. This is QLF: we do not sample a Brownian phase and count what happened — we compute exactly what is most likely to happen. The census *is* the return probability, so every quantity here is exact combinatorics (no Monte-Carlo). The deeper reading (per Jim): **each ZFA closure is a quantum logical system**, and **each renders its own continuum — valid up to the next phase change**. The continuum is not one global object; it is generated closure-by-closure, phase-by-phase, from the exact discrete substrate. That is *mathematics from QLF* (Mathematics_From_QLF.md): the exact census below, its smooth power-law rendering above, and the phase transitions where the rendering switches. Two kinds of phase change appear, both exact: * dimensional (Polya) — the Brownian phase over p conjugate pairs is a walk on Z^p; it is RECURRENT for p<=2 (closes with probability 1) and TRANSIENT for p>=3 (closes with probability 1 - 1/G(p), the Polya constant). The transition at p=2 -> p=3 is a genuine phase change. * scale (octave) — as a closure grows, new irreducible closures appear at each length threshold (half-spin at length 2, two-axis at 4, the 3-axis Borromean proton at 6, ...). Each threshold is a phase change; the cascade rendering (-5/3) holds within an octave regime. Reuses genesis.py (the exact census `multipair_census`, `c_pair`, `slope`) and twist_core (`calculate_action`, `is_pauli_closed`). Instant (no sampling). Anchored: census = Brownian walk (QLF_CensusBrownian); count balance ==> Pauli closure (count_balanced_pauli_closed, QLF_TwistAlphabet); -5/3 forced (QLF_Kolmogorov); no blow-up (QLF_NavierStokesBKM); the continuum-as-rendering (TheContinuum.md, Mathematics_From_QLF.md). The GMC <-> zeta / <-> turbulence ties stay bridge candidates (Riemann-Conjecture-Proof.md).
