* s3tables: build the catalog attribute keys from one shared prefix Every attribute the catalog stores on a bucket, namespace, table or view entry is spelled out with the same literal prefix. Name it once in s3_constants so code outside the package can recognize a catalog entry without repeating the string. Claude-Session: https://claude.ai/code/session_01GfZsc4cyNB2yr6KYLRv9q1 * filer: keep empty folders that are s3tables catalog entries A namespace, table or view is a directory whose extended attributes are the catalog record. Its files can live elsewhere - a rename moves only the catalog pointer and leaves the data at the old path, and a view has no files at all - so an empty one is still a live entry. Drop a table, then rename another table onto that name: the drop queues the old table's folders, the rename recreates the name path, and two minutes later the cleaner deletes it and cascades into the namespace, losing a table the catalog still lists. Claude-Session: https://claude.ai/code/session_01GfZsc4cyNB2yr6KYLRv9q1 * filer: drop a queued cleanup when the folder is created again A cleanup is queued against the folder that was found empty. If that folder is deleted and a new one takes its name, the queue entry outlives the folder it was about and the next pass deletes the replacement. A drop followed by a rename onto the dropped name does exactly this: the name path comes back as a live catalog entry two minutes before the queue is read.
