Different tiers unlock different tiers. Starting from the 12 doors alone:
Hop 1: the 12 open 325 direct relationships — already touching 60 of the Top-100.
Hop 2: those open +1,627 more — deep into the estate.
Hop 3–4: +964 more — the whole researched web (~3,000) is reached.
Add Rob's living contact lines: reach jumps to 23,000.
Rob carries 87.5% of the map. 21,263 direct lines are his. Remove him and the researched web is 3,030.
The core is not the Kings. Only 3 of 12 sit in the core-89. The Kings are doors into 7 different worlds — coverage, not density.
The ocean is cold. Of 10,687 messaged, 8,030 are dormant. Outer ring = potential, not yet a network.
