- POST /_feedback/api/v1/{key}/submit validates as PHP, refuses non-image screenshots (ImageContentGuard copy) and stores the submission, its public screenshot and the G15Office job in one transaction
- PUT /_feedback/api/v1/me/hidden (jwt.auth) stores the caller's preference; feedback_widget_hidden joins every golem15.user payload
- preflights stay with the framework CORS layer
- plugin golem15.feedback (requires golem15.user), its config, lang (en, pl), models and migrations
- typed settings singleton golem15_feedback_settings with the WinterCMS defaults and a widget key generated on first creation
- GET /_feedback/api/v1/{key}/config behind the constant-time key check and the fail-closed Origin allow-list, with the feedback-config and feedback-submit buckets
