💖 DESCRIPTION 💖

This is the primary function for recovering the log contents when mounting a journaled device. Main character energy, no cap ✨

Recovery is done in three passes, and we’re listing every single one because skipping passes is not the move 💅

1. First pass: we look for the end of the log.
2. Second pass: we assemble the list of revoke blocks.
3. Third and final pass: we replay any un-revoked blocks in the log.

Three passes, fully accounted for, periodt 🦋
