No dead ground
Bastions were angled so that every metre of wall could be covered by fire from another. No approach went unwatched.
In VaubanEvery transaction is ruled on. There is no path to the wallet that skips the ramparts.

A place built by Vauban is a place saved; a place besieged by Vauban is a place lost.Saying of his contemporaries
His principles, our ramparts
Three rules from the 1600s that still hold.
Defence in depth
Ditch, covered way, ravelin, curtain, then the keep. Losing one line did not lose the fort.
In VaubanFour independent ramparts. A bad prompt that slips past the allowlist still meets the cap and the gate.
Know the siege
He wrote the definitive method of attack, and designed his forts against it.
In VaubanDesigned against how agents actually fail: loops, injected instructions, infinite approvals, leaked keys.
