Cognitive fabric
The per-user structure ABR grows from experience instead of loading a shared foundation checkpoint.

Fabric primitives
AbrBrain stores concepts, relations, experiences, constructions, programs and promoted symbols. Later v0.24 stats also expose theories, abstractions, grounded constructions and indexed predicates when the native build supports them.
Evidence state
Concepts and relations carry evidence states such as observed, repeated, supported, stable, contested, contradicted and superseded. Reinforcement changes evidence strength rather than treating every sentence as equally certain.
Isolation
ABRManager creates a separate native AbrBrain and PersonalBrain per user id. A persisted fabric envelope includes the owner id and is rejected if the owner does not match.
Inspecting the fabric
GET /api/abr/fabric returns bounded concept/relation views for the current identity. GET /api/abr/status returns stats plus whether the current request is attached to an account or guest.
