M4's GUID-only classifier read a tab-switch between two Save-As forks (shared
copied GUID, different paths) as a Save-As and clobbered a bank. Thread
sameProjectObject into classifyProjectTransition: a different object always
Loads, never relocates; a forked sibling gets re-GUID'd to diverge.
Add forever-stable "view_state" key under the "reasampler" namespace.
saveToActiveProject additionally serializes the ViewModeModel;
loadFromProject restores it on every load path, defaulting on an
absent/malformed key. Model state only — no visibility apply (D4).
Serialize BankIndex to project ext state ('reasampler'), reload on project
load, resolve paths project-relative. Save-As copies the bank to the new .rpp;
identity keyed off a minted GUID (not the recycled ReaProject*) so project
switches don't clobber banks. Pure classifyProjectTransition tested.
