# Historic SQL Table Digest
Use this skill when the WorkUnit raw file is one `tables/<schema>.<name>.json` file from the `historic-sql` adapter.
## Required Workflow
1. Read the WorkUnit notes first.
2. Call `read_raw_file` for the single `tables/<schema>.<name>.json` raw file.
3. Read `manifest.json` only if the table JSON omits the dialect or the WorkUnit notes are unclear.
4. Produce one concise usage narrative for this table from the staged table JSON.
5. Call `emit_historic_sql_evidence` exactly once with `kind: "table_usage"`.
6. Stop after the evidence tool succeeds.
