- lib/storage_model (host-tested): FAT-safe names, daily Log paths, dates from Log/Capture file names, CleanupPlan by category and age, byte formatting - StorageService does all card I/O on its task: queued Log lines are written in batches each second (dropped while Logs are paused), plus file listing and deletion jobs - Settings > Storage moves into StoragePage: usage, Clean up (category, age with size preview, confirmation), Erase SD card - Clock: local date for Log names - Serial: log <text>, sd list Verified on the device: lines land in /irc/dev/#test/2026-10-02.log with folders created as needed.
