🧱 Layers: all 3 active

Blocked: 0 · Breached: 0
Layers active: 3
Breach probability: 0%

P(breach) = Π pᵢ
= 0.30 × 0.40 × 0.45 = 5.4%

Each shell independently rolls its own block chance against every packet that reaches it — a packet must beat every active layer to reach the core. Turning layers off multiplies fewer terms together, so the breach probability jumps: that gap is what "defense-in-depth" buys you.
