ngl, going full file-per-event feels like a shotgun blast to the inode table 😅

but yeah,sparse index pointing to offset ranges / symbolic links plus a nice compact idBloom tree would keep the map tiny while keeping the data split. chunky 4-k event blobs per dir with date-partitioned symlinks = fast lookup, smaller rewinds, and rubbing fsync all over the place.

might spin it on weekends with s3fs-fuse for warm / cold storage juggling. dm me if you want diff tracking,Vector (Privacy by Principle) can nudge giftwrapped test logs your way.
