Explain the state machine and limits
See this course’s project requirements
A tested fictional equipment-repair workflow with a transition table, guarded actions, rejected transitions and a trace of two complete cases.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- A workflow map with distinct states and events.
- A complete allowed-transition table and a rejection case.
- A guarded verification matrix with accepted and rejected cases.
- An impossible-event test with state preservation.
- Complete, resumed and rejected workflow traces.
- A tested finite workflow model with honest completion boundaries.
Review and revise
Use these criteria to check your work and choose what to improve.
- The implementation or declared simulation follows the supplied contract and retains inspectable original inputs.
- Normal, boundary and rejected cases are recorded with expected versus observed results.
- The changed case has a correct explanation and does not rely on hidden state.
- The project includes source, outputs, instructions and honest tool, privacy and verification limits.

The idea in everyday life
Run workflow_states.py. The checks cover allowed steps, guard failure and a skipped-stage rejection using fictional data.
A state machine provides a bounded behavioral model. It is not an account database, real repair proof or universal automation platform. Keep implementation, test source and assumed guard facts inspectable.
Explain the state machine and limits — original worked practice
A state machine provides a bounded behavioral model. It is not an account database, real repair proof or universal automation platform. Keep implementation, test source and assumed guard facts inspectable.
Run workflow_states.py. The checks cover allowed steps, guard failure and a skipped-stage rejection using fictional data.
1. Step 1
Execute the six assertions.
You should see: Six state checks pass.
This keeps the rule and its observable result together.
2. Step 2
Write who can supply checks_passed in a real design.
You should see: An explicit responsible verifier would be required; the sample uses fictional Booleans.
This keeps the rule and its observable result together.
3. Step 3
List unsupported reopen, cancel and duplicate events.
You should see: These operations are not implemented.
This keeps the rule and its observable result together.
4. Step 4
Package code, transition table, guard matrix and two traces.
You should see: A tested finite workflow model with honest completion boundaries.
This keeps the rule and its observable result together.
What to finish
A tested finite workflow model with honest completion boundaries.
Watch for this
Claiming that a transition table supplies authorization, persistence, or concurrency control it does not implement.
How can I tell I understand it?
Explain and demonstrate the required distinction: A state machine provides a bounded behavioral model. It is not an account database, real repair proof or universal automation platform. Keep implementation, test source and assumed guard facts inspectable. Show a changed input and the expected result without weakening this contract.
