To ensure your heirs can access your bitcoin after you pass away, all of your P2WSH addresses contain a second spending clause that after 1 year, a second key (held by your heir) can spend all of your outputs. With this program/script, you want to be able to quickly “refresh” all outputs that are coming close to being unlocked, e.g. within 3 months of the second spending path becoming viable. See https://bitcointalk.org/index.php?topic=5185907.0 for an example of the original setup.
