id4_common.utils.run_engine_init

Local copy of apsbits.core.run_engine_init.init_RE that fixes the broken handler_name selector. Upstream apsbits 2.0.1 hard-codes handler_name = StoredDict (the class object) and then compares it to the string "PersistentDict" / "StoredDict" — both branches are always False, so RE.md is never wired up to the on-disk PersistentDict and scan_id (etc.) never restore on startup.

Drop this shim once apsbits ships a release that picks the handler from the path layout instead of pinning it to a class.

id4_common.utils.run_engine_init.init_RE(iconfig: collections.abc.Mapping[str, Any], subscribers: list[Any] | None = None, **kwargs: Any) → tuple[bluesky.RunEngine, bluesky.SupplementalData]

Initialize and configure a Bluesky RunEngine instance.

Mirrors apsbits.core.run_engine_init.init_RE(). The only behavioural difference is handler_name, which here selects "StoredDict" for a file MD_PATH and "PersistentDict" otherwise — the upstream version hard-codes the class and never actually restores from disk.
