Operator Closure · Paper 21
Paper 21 v2.0 is a scope-reduced release focused on AC1 acoustic closure, SU(2) puncture-load construction, Big Bang nucleosynthesis branch assignment, and R4/FIRAS dependency auditing.
If the theory is correct, the math will just work.
Paper 21 — Acoustic Closure and Puncture Construction
Paper 21 v2.0 supports the AC1 acoustic theorem chain, the SU(2) puncture-load values L_1 = 0.22417 and L_2 = 0.13805, and the Big Bang nucleosynthesis branch assignment. The v2.0 support bundle adds R4/FIRAS dependency auditing and excludes the retired radiation-response route investigation.
