+"""The CLI's session store must be the registry's shared handle for state.db.
+
+``_init_session_store`` used to construct a bare ``SessionDB()``. The goal/loop/heartbeat
+managers acquire the same path through ``hermes_state_registry`` from the REPL thread a
+moment later, so a bare handle meant a SECOND full open — including the /proc-wide
+deleted-WAL sidecar scan (~4k readlinks, each a GIL round-trip against the busy startup
+threads) — which showed up as the post-banner freeze before the first prompt.
