$100\Omega_c = 37.6 \approx \phi_{birth}=37.6439^\circ$
$\phi_{Node6}-\phi_{birth}=8.9979024518^\circ$
$360^\circ-351^\circ=9^\circ$
Closure residual:
$|9-8.9979024518|=0.0020975482^\circ=7.55117352''$
Under the stipulated null probability
$p=1/44{,}000{,}000=2.27272727\times10^{-8}$,
the one-sided Gaussian-equivalent significance is
$Z=5.4682324795\sigma$.
ALL NUMERICAL ASSERTIONS: PASS
The 5.468σ conversion is conditional on the stipulated p-value above.
