Rewrite from last
rewrite_from_last is an append_policy used with write_mode=append.
Behavior
- Takes the last date present on the sheet
- API range:
last_sheet_date … today - Deletes sheet rows from that date onward and rewrites the range
Not a positional "last row of the previous run" marker — the reference point is the date in the date column.
When to use it
When you need a hard rewrite of the tail from the last date, without the overlapping soft-refresh (−1 day) behavior.
