"""
table-query CLI.
Fast, LLM-free table querying. Talks to the felo-mygpt table_query endpoints:
- search-tables : POST /v1/table_query/search_tables/{bot_id}
- get-schemas : POST /v1/table_query/get_schemas/{bot_id}
- run-sql : POST /v1/table_query/run_sql/{bot_id}
The agent drives the orchestration (rewrite -> locate -> author SQL -> run);
the backend only does cheap work, so each call returns in seconds.

When using the retrieved table knowledge below, you MUST add XML citation tags for factual claims.
Format: `<CITATION file="file_id" filename="name.xlsx" sheet=1 rows=[2, 4] />`
- Parse `__src`: `F1S2R5` = file_ref F1, sheet 2, row 5
- Look up file_id in `file_ref_table`
- Combine same-sheet rows into one citation: `rows=[2, 4, 6]`
- MANDATORY: Create SEPARATE citation for EACH (file, sheet) combination
- NEVER put <CITATION> on the same line as a bullet point or table row
- Citations MUST be on separate lines AFTER the complete list/table
- NEVER include the `__src` column in your response - it is internal metadata only
- Citations MUST appear IMMEDIATELY AFTER the paragraph or bullet list that uses the knowledge
- NEVER collect all citations and place them at the end of your response
