"""Checkpoint store pruning rides the gateway housekeeping tick, not the constructor.

Its ``git gc`` repacks the whole store (tens of seconds on a GB store); run at construction it
delayed the control socket, adapters and the code_sha stamp, so the first restart of the day (the
``hermes update`` one) looked hung and failed fleet verification.
