What is proved
From benchmarks/hvac/fbd_fan_damper/props.yaml. What each kind claims, and what it becomes on either route, is on The properties we prove.
| id |
kind |
claim |
requirement |
P1 |
invariant |
!(fan && !damper_open) |
The fan must never run against a shut damper: the duct sees full fan static as vacuum and can collapse. |
P2 |
invariant |
!(fan && smoke) |
A running fan distributes smoke through the served zones, so a duct smoke alarm must drop the fan. |

Recorded runs
A task can carry two routes. ld is ESBMC's ladder front end reading the program directly. via C is the same solver reached through Beremiz and MatIEC, which is the only route that reaches ST, IL, FBD and SFC; see How ESBMC-PLC works.
