Worktrees
byre worktree fix-flaky-tests
creates a linked git worktree on branch fix-flaky-tests (existing or
new) and starts a session in it. The worktree inherits the repo’s config,
image, and volumes – the agent is already logged in – but runs in its own
container against its own checkout, so sessions run side by side.
Worktrees you made yourself with git worktree add inherit the same way:
just byre develop in them. You pick once where new worktrees live
(byre config --global). Commits land in the shared object store,
byre status shows every worktree session in the project, and
reset/forget name their blast radius before touching anything shared.
