Name this thing

Suggest names for something that {{what}}, living in {{context}}.

Six options. For each, one line on what a reader would assume from the name alone
— including the wrong assumptions. Prefer names that describe what it is over what
it does to you, and avoid Manager, Helper, Util, and Handler unless the thing
genuinely is one.

End with the one you would pick and the strongest argument against it.

What to fill in

{{what}}

What it does — e.g. opens the store, migrating or recovering as needed

{{context}}

Where it lives — e.g. a shared persistence helper used by both apps

What it produces

PersistentStore.load(at:)  — reads as "load the store", which
  is what it does. Hides that it may recover.
StoreOpener               — noun-agent naming; reads like a
  factory, implies no recovery.
StoreLoader.open(at:)     — clearest at the call site, but
  Loader is close to the Manager family.

Would pick PersistentStore.load(at:). Against it: nothing in
the name warns you it can move data aside.
