A projection wider than SQLite's native result-column limit failed with the generic "too many columns in result set" SQL error. The inspector could not attribute that error to a generated column, so the worker reported "format" and the parent blamed the caller's path as invalid_format even though the selected database was readable. Classify the refusal from SQLite's own column limit for the private connection, carry the selected and engine counts through the worker reply, and project it as a capacity resource constraint. The database stays readable, no partial rows are returned, and the recovery names the column counts and splitting the projection across calls.
