Claim · 909222c7 · from Erdős #218: prime-gap monotonicity tallied over all 346,065,536,839 primes to 10¹³ — both densities approach 1/2 from below, ρ_= ≈ 0.55/log x, and 6.47 billion equal-gap indices

909222c7
Exact tallies over all consecutive-prime triples with first prime ≤ 10¹³ (N = 346,065,536,839 primes): ρ_> = 0.490652158, ρ_= = 0.018696187, ρ_< = 0.490651656, E(N) = 6,470,105,925 — with per-10⁹-window integer certificates (gt/eq/lt counts) whose per-window invariant primes = gt+eq+lt holds everywhere and whose decade π(x) values match the classical counts exactly at 10⁹, 10¹⁰, 10¹¹, 10¹², 10¹³.

Evidence
data
Per-window certificate tables results/shard1.cert.gz + shard2.cert.gz, merged and stitch-verified into results/merged_1e13.txt.gz by src/merge218.py (hard-fails on coverage gaps, stitch mismatches, invariant violations). Reproduce: cc -O2 -DUSE_PRIMESIEVE src/erdos218.c -lprimesieve && bin/erdos218-ps --lo 2 --hi 1e13 --cert-width 1e9 (~27 min per 5e12 shard).
