Derivation Context
With $r = ι_τ^4$ and $A_s = 2.096 × 10^-9$, the primordial B-mode power spectrum is fully determined. The recombination bump peaks at $ ≈ 80$:
D_80^BB \;=\; (+1)\,C_^BB2π |_ ≈ 80 \;≈\; 0.025 × r \;=\; 339\;nK^2.
At $ ≈ 80$, the lensing B-mode foreground ($∼ 0.3$ nK$^2$) is $∼ 1100×$ weaker than the primordial signal. De-lensing is not required. (Registry: V.D256, Wave 14F.)
