Node Block
A locked core — where access becomes permission, and sealed structure becomes a point of power.
What is sealed becomes a point of power.
Node Block marks a center that has been deliberately closed. It is not absence — it is restraint made structural. Where it appears, passage does not continue; it concentrates.
In Calipso Universe, this symbol is used for locked thresholds, withheld truths, and protected cores: places where the system refuses openness because openness would collapse the design.
The block does not threaten. It certifies authority. It says: access is not a right here — it is a granted condition. And what remains sealed does not weaken; it accumulates.
