+-- One-off (2026-10-12): every table of this project starts with CV_.
+-- Renames the results table created before that rule, and its two indexes,
+-- to the names tools/sql/create_tables.sql now uses. Run once in SSMS as a
+-- login allowed to alter the table (e.g. sa). Data, columns and the
+-- Windows login's read/write grant are kept. Safe to run again: each step
+-- only runs when the old name is still there.
