What is Engine?
A grounded explanation of Engine, the current implementation, and the boundary between vision and evidence.
What Engine is not
Non-goals, product boundaries, and a cautious comparison with other project categories.
Architecture
The canonical Engine action lifecycle, v3 plugin autonomy, stores, roles, and authority boundary.
Heart and brains
What the Heart, general brain, and multiple specialist brains mean and how they work together.
All modes and statuses
Engine taxonomies for autonomy, goals, cognition, invocation, policy, evidence, learning, routines, and Homey.
How Engine learns — and does not learn
The distinction between state, experience, preferences, routines, plan reuse, and future model weights.
Generic plugin autonomy
Modes, enrollment, templates, cognition routing, recovery, and authority in engine.plugin/v3.
The end goal
Engine's long-term direction, with explicit evidence boundaries and falsifiable intermediate steps.
Engine Cell
The evidence gate for a future bounded local specialist and the first honest no-go.
