Concepts

The four documents you'd read first:

• SPEC — what Gaby is for, who it's for, what it must do.
• Architecture — how Gaby is built. Agent loop state machine, safety pipeline, memory hierarchy.
• Foundation — the locked stack and the v0.1 exit criteria.
• Agent loop — narrative deep-dive into the state machine and prompt cache layout.
• Safety pipeline — why Gaby refuses things and how the authz matrix works.
