I download filedumps where filesizes are same, but filenames are vastly different. And so I am requesting a FILESIZE *only* option for GeneralSettings.mirrordetectiondecision, unless there's a better way of doing this with existing options.

In the example below, I would prefer the second link never be added to the package by Linkcrawler, but I'd also be fine with the dupe file treated as a mirror during download. Currently, starting download on the package below downloads both files even though they are identical bytes - verified both pre-download, and post-download inspecting the files on disk. What settings should I be using?

As I understand it, FILENAME_FILESIZE in Advanced Settings -> GeneralSettings.mirrordetectiondecision is an AND, not an OR. Meaning filesize check only matters if filename is also the same. I've read many threads and tried many combinations of mirror/dupe detection settings, but cannot find a way to prioritize identical bytesize as a dupe positive.

Afaik this is not planned.
I recommend using an EventScripter script which checks for same filesizes and simply deactivates all items which have been detected as dupe.

This will easily break many downloads. For example split files/multipart archives all files except the last one of archive/split have the same file size. With this setting enabled, you no longer will be able to download the files. It also breaks when user wants to download the same file multiple times, eg from different hosters

Can you provide example links for your situation? maybe it's possible to find different approach, eg filesize+hash in case the plugin/site does provide checksum information.

This is another reason why I do not see any normal use-case here.

An EventScripter script will easily help to do this.
