Changes

• FCS files are read as a stream: a 250 MB tube (3 million events) loads without the whole file being held in memory. Values are identical to the previous reading, checked bit for bit on a real 243 MiB file.
• The FCS file limit rises from 100 to 300 MiB. A file that is too large is refused before upload, showing its size and the limit, instead of a generic message.
• A tube can be removed from an analysis (trash icon or right click, with confirmation). Its FCS file is voided and kept, not erased; its name becomes free again and the run can be imported again. The action is recorded in the audit log.
• Studies list: Archive and Restore button on each row; archived studies are hidden by default and found with the Archived filter.

Known limitations

• Loading very large files remains bounded by the server's memory: several 250 MB tubes requested at the same time queue up.
• Values already sent to the workbook or to the execution before a tube is removed stay in place.
• The gates and validations of a removed tube are kept in the database (a validation cannot be deleted) but no longer appear in the analysis.
