OrientationThe Same Transition, a Fourth Time
By this point the structure of a domain chapter is familiar, which is the argument. A cognitive state-change is a contact-normal-form transition with three numbers substituted in, and the substitution is the only thing that changes between rooms.
Substituting into the normal form
U delivers a new behavioural mode: the post-transition oscillatory regime, stable, and not reachable in reverse by removing the input that caused it. Irreversibility is the same property the pedagogy chapter relies on when it claims a student cannot unlearn compression.
Identity Across the Four RoomsWhat Is Actually Being Claimed
The claim is not that these four systems are similar. It is that they are objects in one category, related by explicit contact morphisms — that the same normal form obtains, and that identifying a system means measuring (μ_max, ω, β) rather than proposing a model.
It is worth being precise about the strength of this. Darboux’s theorem makes the local contact geometry identical for free: every contact form is locally α = dz − y dx, so finding the same local structure in four rooms is not by itself evidence of anything. The content is in the dynamics carried on the structure — in the specific normal form, the rank-one Hessian degeneracy at the fold, and the numerical bands. Those do not come free.
Stated that way, the identity claim is falsifiable in a useful direction: find a generative transition whose Hessian loses rank two, or whose residual is not O(ρ²), and the category is smaller than advertised.

- Ch 15 · Market · The Generative TransitionThe same table again, in the room with the worst instrumentation and the best data volume.
- Ch 20 · The Coherence Bridge TheoremWhere the four rooms are stated as one category, and where the claim is at its most exposed.
