# the three tiers (structure)

Six terms, then a model, then a self-model, with boundaries at the coordination and reflexive transitions. Falsified if a blind test scrambles their order: words about pure structure needing a model, or words about self-reference closing in six.

**Through:** The components interact to form a layered structure where increasing constraint from six terms through model to self-model is maintained by feedback, falsifiable by drift in unobserved parameters that disrupts the order essential to pure structure and self-reference.

**Novel properties:**
- layered constraint
- reflexive transition
- falsifiable order

## Examples
- The Linux kernel's versioning system uses six development stages, a stable release model, and self-documenting changelogs maintained through automated testing. *(computing)*
- The U.S. Constitution established three branches of government, a system of judicial review, and a self-amending process tested by Supreme Court rulings over time. *(institutions)*
- A bee colony maintains six types of pheromones, a queen-centered regulation model, and a self-monitoring feedback loop during swarming cycles. *(biology)*
