MISSION DEbRIEF
You investigated a real-world system. You learned that: • diagrams are not proofs • AI suggestions must be validated • correctness requires formal reasoning
CONTINUE
REFLECTION
• Which assumption turned out to be wrong? • Where did AI mislead you? • Which rule was most critical?
FINALIZE
ENGINEER’S DECISION
You cannot fix everything. If you had time for only ONE change: • what would you fix • and why?

Got an idea?
Use this space to add awesome interactivity. Include text, images, videos, tables, PDFs... even interactive questions! Premium tip: Get information on how your audience interacts with your creation:
- Visit the Analytics settings;
- Activate user tracking;
- Let the communication flow!
If a state is reachable,it must be safe. Forbidden states must be explicit.
AI may remove or weaken problematic rulesto make the system appear correct. Never remove a rule without justification.
Sequence shows order.Activity shows decision logic. Missing branches hide failures.

AI often invents unnecessary actors.Validate each one.
Structure enables behavior,but does not guarantee correctness.
AI often proposes over-detailed class models.Prefer clarity over completeness.

“AI is used as a learning catalyst — not as an authority.”
If a rule is not explicit,it can be violated. Invariants define what must always hold.
Focus on WHO interacts with the system,
not how it is implemented.
AI often models the happy path only.Check error and alternative flows.
Correct structure does not guarantee correct behavior.Look at the order of interactions.
