"""C26 wiring: the boot registry is reached by the real entry points, and
the cadence has a production caller.

Proven with real imports against a temp HERMES_HOME; the external
boundaries (pm store, network check seams, process identity) are
stubbed — the wiring itself is exercised through the exact public
invocation (``hermes_cli.main.main()``, ``gateway.run`` housekeeping).
