## Keep visitors' existing choices

v3 uses the same `c15t` cookie and storage key as v2 and reads v2 records. It
does not rewrite them on page load; the next accept, reject or save writes a
v3 record.

A v2 denial keeps restricting its category. A v2 grant keeps applying until
the policy's validity period runs out, and then c15t asks again. If the rule
comes from a preset and the v2 record noted the policy it was made under, c15t
also asks again when that policy has changed. Under custom rules, a v2 grant
applies until it expires. Do not copy permissions into new
records yourself; c15t decides which v2 choices still count.
