[F] setAutoDecorator

function setAutoDecorator(
   program,
   decoratorFqn,
   target,
   value?): void;

Programmatically apply an auto decorator to a target, storing its argument values.

Mirrors what the synthesized auto dec implementation does when the decorator is written in source, so emitters and mutators can mark synthetic types the same way without reaching into the program state map directly.

Parameters

Parameter	Type	Description
program	Program	The current program.
decoratorFqn	string	The fully-qualified name of the decorator (e.g., “MyLib.myDec”).
target	Type	The type to mark.
value	Record<string, unknown>	The stored { paramName: value } record (defaults to {} for a no-arg decorator).

Returns

void
