phpstan-type-trace

Use when a PHPStan/Larastan type error is NON-TRIVIAL to fix by reading the source alone — the variable crosses multiple scopes (closure, callback, helper), is shaped by a third-party extension (larastan Eloquent magic attributes, webmozart/assert, doctrine generics, dynamic-return-type extensions), lives in a method longer than ~30 lines, involves generics / array shapes / template parameters, or a first read of the source already failed to explain the inferred type. Call the phpstan-trace CLI to retrieve the full type-inference chain BEFORE guessing a fix. Skip for trivial errors where the source obviously explains the type at the error line.
