Python's sqlite3.executescript() has a bug where trailing newlines after the final semicolon create empty statements. When APSW's log_sqlite() is enabled (via apswutils, imported by fastmigrate), these cause visible "API called with NULL prepared statement" errors during interpreter shutdown. - Strip trailing newlines from all 9 existing migration files - Update migration template to end with semicolon, no trailing newline - Document the requirement in CLAUDE.md 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
