Output-order diagnosis

Search every write affecting the identifier:

• every set_val affecting the identifier;

• swap/block/sensitivity/deadzone/stickize;

• polar setters;

• remap/unmap;

• menu/test/auth gates;

• user functions called later in main;

• active combos or called user functions that write the identifier.

Then write the intended order down. "This block runs first" is often the bug.
