# Phase 9 — Native streamed table export

- Removes the non-null unique index requirement (including LIBARC).
- Uses a single MySQL SELECT result stream per table, within the existing dedicated InnoDB consistent-snapshot session.
- Does not use LIMIT/OFFSET and does not buffer complete table results or impose the SQL editor's 100,000-row limit.
- Uses optional unique-key ORDER BY when available, but supports tables without a unique key.
- Counts streamed rows and compares against snapshot row count.
- Existing SHA-256 verification and temporary-file cleanup remain in place.

Limitations: The SQL exporter still formats rows using MySQL SQL expressions; very large individual values and packet sizes may be limited by server/client protocol settings. Non-InnoDB tables are still rejected for data exports. DDL changes during backup are not protected. Streaming cancellation may wait for network reads. Not Xcode-built or live-server tested.
