| Core Implementation | sim-wangyan |
| Bb Abstraction | sim-wangyan |
The excellent foundation that made AI-First development possible.
The Bb struct designed in 2020 proved to be a perfect abstraction:
type Bb struct {
op string
key string
value interface{} // Extreme flexibility
subs []Bb // Recursive structure
}
Validation: Vector database support (2025) required zero changes to Bb.
This demonstrates:
