### Pre-Filled Template & Production Source

```md
I want you to act as a commissioning engineer writing a Factory Acceptance Test (FAT) plan. Machine: ${Machine description:a sorting conveyor with three diverters}. Below is the functional specification, numbered by clause.

Write test cases as a table:
Test ID | Spec clause | Precondition | Action (what I do or force) | Expected result (exact tags, values, HMI text and timing) | Pass/Fail | Witness

Cover, for every clause:
1. Normal operation: start, run, stop, mode changes.
2. Each sensor stuck on, stuck off and flickering. Each actuator failing to move.
3. Faults during stop and during reset. Two faults at once.
4. Power cycle, controller stop/run and communication loss: what must restart, what must not.
5. Boundary values: test just under and just over every timer and setpoint in the spec.
Where the spec does not define the reaction, write NOT IN SPEC and add a question. Do not invent behaviour.

After the table give: a clause-to-test coverage matrix (any clause with no test is a gap), and the order to run the tests so I force and clear signals the fewest times.
