62	* Whether the current user may edit the given media item.
63	*
64	* `upload_files` is a primitive capability and ignores any object passed to it,
65	* so it only tells us the caller may upload something, never that they may edit
66	* this particular item. A missing item is passed through so the caller receives
67	* the endpoint's own 404 rather than a 403. A userless request gets no exemption:
68	* `edit_post` fails closed for user 0 like any other caller.
69	*
70	* Non-attachments are refused outright. `get_post()` resolves any post type, so
71	* without this test a media endpoint edits ordinary posts, pages and revisions.
72	* The post-type test must stay below the missing-post passthrough: that branch
73	* returns true, so testing there would skip `edit_post` for ordinary posts.
74	*
75	* A non-attachment yields 403, not the 404 a missing item gets. This is a boolean
76	* gate, and `get_media_item*()` resolves any post type, so a passthrough would
77	* return 200 rather than 404. Revisit if clients conflate it with an auth failure.
78	*
79	* Do not move this into a trait: this file instantiates the endpoint above the
80	* class declaration, and `use Trait;` disables PHP early binding, which makes the
81	* file fatal with "Class not found".
