  12# P vs NP Assembly: Complete Resolution Structure
  13
  14Two resolution paths:
  15
  16**Path A — P ≠ NP (conditional on UniformTopologicalObstructionHyp):**
  171. J-frustration is non-natural (Phase 2) → RR barrier doesn't apply
  182. UNSAT formulas have J-frustration ≥ 1 (Phase 1)
  193. High J-frustration implies exponential circuit size (Phase 3, conditional)
  204. SAT is NP-complete → no polynomial circuit family for NP → P ≠ NP
  21
  22**Path B — Dissolution (unconditional RS position):**
  231. R̂ recognition time for SAT ≤ n (proved)
  242. TM simulation of R̂ requires overhead (structural argument)
  253. P vs NP conflates two distinct complexity measures
