THE MARS GRID

The previous Part derived the problem. Now we can finally show the answer.

Mars GRID is Matlas's system of persistent area identities: one nested geography covering the whole surface from planetary scale down to areas roughly a kilometre across. Its canonical hierarchy is:

Mars → Quad → Zand → Province → Sector → Tile → Click

Seeing the hierarchy is the easy part.

The harder question is whether it survives everything Mars asks of it.

Part III therefore moves through five stages:

Reveal — what is GRID?
Planet — how is Mars divided at the largest scale?
Hierarchy — how does the system descend from Zand to Click?
Identity — how does a place stay the same place?
Polar — what happens when longitude collapses towards the poles?

The sequence is deliberate.

First show the architecture.

Then try to break it.
