Films as behavioral proof

Evidence in motion.

What happens when the AI engineering method meets a system with real boundaries?

Commerce is the test bed. Nineteen films are the unit of visible proof. As-built documents in Reference explain the mechanism underneath—without replacing the film as the primary evidence.

Start with engineering pressure

Concurrency. Propagation. Feedback.

Three hard proofs before the full film index—matching the laboratory thesis, not a customer lifestyle tour.

Choose an engineering pressure.

Each capability groups films first. The as-built is the mechanism appendix in Reference—open it after the visible proof, not instead of it.

Behavior first, mechanism second

See the result. Trace the mechanism. Challenge the claim.

Films establish visible proof. As-built documents in Reference explain ownership, events, state and limits. Narration never replaces either.

Optional orientation: Business Flow Showcase — a commerce lifecycle overview, not a substitute for the films.
