Centralise the binary file saving metadata #3442
Description
Following on from a discussion at #3245. At present there is a binary.json metadata file written during the saving of binary data. This duplicates the si_folder.json metadata which has caused some problems with failure to propagate metadata and confusing behaviour during debugging #3245. The logic flow for the data-saving is discussed here. It would be nice to completely deprecate binary.json and use only si_folder.json to centralise the metadata.

I’d be happy to help with this. Since #4671 moved properties, annotations, and probe metadata into separate files, is deprecating
binary.jsonstill the intended direction?Would you prefer keeping it as the binary-storage configuration, with
si.load(folder)documented as the way to restore the complete recording, or migrating away from it while retaining support for older folders?I’d suggest a small first PR for the agreed direction, with regression tests covering properties and annotations on save/load, plus legacy-folder compatibility. I’d leave new metadata fields and fingerprints out of scope. Happy to put together the implementation once the direction is clear.
