Isolation, without the stash dance
Each session runs in its own jujutsu workspace, isolated on disk. And because jj snapshots the working copy continuously, your in-flight edits are always already part of the change — so a new session branches from exactly where you are, uncommitted work and all. No stash, no clean-checkout surprise, no half-finished rebase to recover from.
