Leaf	Required evidence	State
Certified prefix $n\le 10^6$	Residue sieve plus independent trial+Pollard; Wolf $\pi_q(10^{12})=54110$	certified (`compute/`)
Certified prefix $n\le 10^7$	C residue sieve plus independent C/Python trial+Pollard; Wolf $\pi_q(10^{14})=456362$	certified (`q2/`)
Certified prefix $n\le 10^8$	C residue sieve plus independent C trial+Pollard; Wolf $\pi_q(10^{16})=3954181$ ; $\Omega=2$ count $12172983$	certified (`q3/`)
A prime $n^2+1$ off Grantham–Graves	Construction with $n\gtrsim 2.5\times 10^{14}$	blocked (range)

The Iwaniec $P_2$ table on a stated range is not in Wolf, OEIS A083844, or Grantham–Graves. Infinitude of primes $n^2+1$ is not a finite handle.
