Audit of the "agents barely communicate / nothing runs" reports: the
bootstrap run, hiring, delegation, channel messages, file handoffs, and
heartbeat continuation are already covered by autonomous-run.test. The one
untested link was the round trip — an @mention actually waking a teammate
who then replies. This test drives a scripted CEO that hires an engineer
and @mentions them in #engineering, asserts the mention created a queued
chat_mention run for that engineer, executes it, and confirms the engineer
replies inside the same thread (two senders, one thread). The orchestration
is sound; real-world silence is a function of the model's tool-use, not the
control plane.
