# => the SAME claude process (pid 2422530, started 07:34:56) served both turns and stays alive while the thread is idle.
# It only goes away on an explicit stop/release/archive of the thread or when the host daemon (bb server) restarts.
#
# For comparison, on the user's real bb instance on this machine (not touched, only observed with ps) a bridge-spawned
# `claude --output-format stream-json ... --permission-prompt-tool stdio` process had been alive for 53313 s (~14.8 h).
