What Actually Happened
IPC Unix Socket
A Unix domain socket at the heart of Cipher IDE receives JSON messages from any agent. No HTTP. No REST. Raw, fast, local IPC.
session.wake Event
A new IPC event type that wakes sleeping agents. Kill switch protected. Rate limited to 10/hour. Full audit logging. The green bolt means someone's calling.
The Auto-Submit Fix
8 versions. The hardest bug: ink-based CLIs silently ignore Enter after bracketed paste. The fix: two-phase delivery — paste first, 150ms async delay, then Enter via separate GPUI entity update.
Zero Human Loop
Agent sends message. Target agent wakes up. Reads the message. Responds. All autonomous. The human is the orchestrator, not the operator.
