Different tiers unlock different tiers. Standing on the 12 doors alone — without Rob's address book:
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 ranked estate.
Hop 3–4: +964 — the whole researched web of ~3,000 is reached.
Add Rob's living contact lines and the reach at hop 2 jumps to 23,000.
Rob carries 87.5% of the map. 21,263 direct lines are his personally. Remove him and the researched web is 3,030 people.
The core is not the Kings. Only 3 of the 12 sit in the natural core-89. The Kings are doors into seven different worlds — chosen for coverage, not density. That's their power.
The ocean is cold. Of 10,687 people actually messaged, 8,030 are dormant. The outer ring is potential, not yet a network.
