Brandon Schneider 61ee34b58f feat(lean): genus-1 torus carrier — winding numbers, surface braids, and C1/C2 lane formalization
Three interconnected additions resolving the genus-1 vs genus-3 topology
question through structural derivation from the gap-6 prime lane pair:

(a) Burgers-PhiNUVMAP bridge (PistSimulation.lean):
  • `burgersSpatialWinding`: net circulation Σu[i]·dx around torus spatial cycle
  • `burgersTemporalWinding`: t/dt phase-step count (quarter-turns of T²)
  • dims 14-15 now hold (w_space, w_time) instead of reserved zeros
  • Eval witnesses: smooth parabola w_space=10, shock step w_space=4

(b) Torus surface-braid enrichment (BraidEigensolid.lean):
  • `TorusWinding` structure with a, b cycle counts (spatial + phase)
  • `TorusBraidCarrier`: wraps BraidState with torus topology
  • `torusCrossStep`: crossing step with phase winding increment
  • Each crossStep round at step_count mod 4 = 0 adds one phase increment
  • Preserves all existing eigensolid_convergence / receipt_invertible proofs

(c) Genus1TopologyMetaprobe.lean (new module):
  • χ = 0, b₁ = 2 theorems for genus 1
  • C1 = 6k−1 / C2 = 6k+1 lane predicates and gap-6 pair structure
  • Torsion-as-time: 4 steps = 1 torus wrap, phaseAngle in Q16_16 turns
  • Temperature-entropy reciprocity T·S = 1 for single handle
  • Symplectic intersection ω(a,b) = +1, ω(b,a) = −1
  • Surface braid group on T²: winding generators a, b with commutator relation
