Harbour of
Three Walls
Shape three breakwaters. Incoming wave trains refract over the shelf, reflect from stone, and spill through gaps. The useful harbour is not simply the quietest one: a vessel still has to enter.

Reference passage book · shoaling shelf
| arrangement | berth / outside | corridor | reading |
|---|---|---|---|
| Open guide | −8.1 dB | 12.7 m | moderate shelter, generous passage |
| Staggered gate | −0.3 dB | 12.7 m | open, but reflected energy reaches the berth |
| Inner hook | −25.6 dB | 8.0 m | strong shelter with a tighter viable turn |
| Sealed mouth | no arrival | closed | quiet water that is not a harbour |
Each entry is the same 1,200-step, 54-second run. They are counterfactuals, not a score: change the seabed, move a probe, or edit a wall and measure again.
