Code stays local
The runner keeps source, tools, and Codex authentication in the customer environment.
Nereid turns agent-authored work into a reviewable delivery packet: what changed, why it changed, what was verified, and what remains risky.
Active delivery
Every state is derived from validated events. Agent prose cannot mark itself ready.
Non-negotiable
The runner keeps source, tools, and Codex authentication in the customer environment.
A failed check is retained and prevents the packet from quietly becoming review-ready.
Only an authorized reviewer can approve. Approval updates a check; it never merges.
