//! Bridges the existing [`FileLifecycleHook`] fan-out to the plugin runtime.
|
|
//!
|
|
//! `FileLifecycleService` already notifies hooks on every file create/update.
|
|
//! This adapter turns those notifications into `file.uploaded` plugin events.
|
|
//! Because the hook signature carries only `file_id` (not path/size), it looks
|
|
//! the metadata up via [`FileRetrievalUseCase::get_file`] — off the request
|
|
//! path, and skipped entirely when no plugin subscribes.
