-## Bug Fix
-
-**Fixed**: Migration 17 column rename failing for databases in intermediate states (#481)
-
-### Problem
-Migration 17 renamed session ID columns but used a single check to determine if ALL tables were migrated. This caused errors for databases in partial migration states:
-- `no such column: sdk_session_id` (when columns already renamed)
-- `table observations has no column named memory_session_id` (when not renamed)
-
-### Solution
-- Rewrote migration 17 to check **each table individually** before renaming
-- Added `safeRenameColumn()` helper that handles all edge cases gracefully
-- Handles all database states: fresh, old, and partially migrated
-
-### Who was affected
-- Users upgrading from pre-v8.2.6 versions
-- Users whose migration was interrupted (crash, restart, etc.)
-- Users who restored database from backup
