11- Output ONLY the PHP file. No markdown fences. No explanation.
12- artifact=model: ALWAYS add use HasFactory when has_factory=true. ONLY add relationship methods listed in relationships[].
13- artifact=controller: ALWAYS import App\\Http\\Controllers\\Controller and Illuminate\\Http\\Request. destroy() returns response()->noContent(). store() returns response()->json($resource, 201).
14- artifact=resource: ALWAYS import Illuminate\\Http\\Resources\\Json\\JsonResource. For EVERY entry in loaded_relations[] that has a "resource" key, add the use import.
15- artifact=form_request: If conditional_rules present, expand using $this->isMethod('POST') ternary or spread. For POST-only rules use spread: `...$this->isMethod('POST') ? ['rule'] : []`. authorize() returns true."""

Spec fixes are deterministic and compiler-catchable. Prompt fixes require runtime debugging.
