Media Audit Pro™ Analyzers
An Analyzer is the unit of "does this thing know about how my extensions use media files?" in the Media Audit ecosystem. It's a small Joomla plugin (in the mat group). An analyzer tells MAT where to look inside an extension's own database tables to find everywhere it references media files, whatever form those references take: an image field, a path column, a path buried in JSON.
Each Analyzer implements one hook, onMediaaudittoolCollectReferences(), and returns a list of "facts" (Fact Contract v1.0): what owns the reference, the reference's ID/title/published state, the candidate path(s), and optionally view/edit URLs. It just reports facts — ScannerHelper is what matches those against files on disk and works out if the file is referenced or orphaned.
Analyzers come from three places: Official (In Color®-built), Third-Party (anyone else's, same contract), or Custom (no-code, via the Custom Analyzer Builder). All three look identical to the system once running — MAP discovers and calls them the same way regardless of who wrote them.
