hermes-agent/tests/run_agent/test_wait_state_visibility.py

"""Tests for wait-state visibility — the live "what are we waiting on" notices.

Long provider waits (slow/overloaded backend, no first byte, reasoning model
thinking for minutes) used to leave CLI/TUI/Desktop users staring at a generic
"cogitating..." spinner with no explanation. ``AIAgent._emit_wait_notice``
rewrites the live spinner/status line (via ``thinking_callback``, bridged to
``thinking.delta`` for TUI/Desktop) and updates the activity tracker (which the
gateway's "⏳ Working — N min" heartbeat includes).
