Module scripts 

Script builders — ports of script_cd / script_mkdir_cd / script_clone / script_worktree / script_delete / script_ascend / script_rename (try.rb:1411-1467). Every byte matters: the emitted strings are pinned by test_05/07/12/16/31/37.

Functions

script_ascend

script_ascend (try.rb:1441-1457): git worktree move when the source has a .git file (worktree marker), plain mv otherwise; then a symlink back into the tries dir, the Graduated: echo (with a literal →), and a cd to the destination.

script_cd

script_cd (try.rb:1411-1413). The leading touch bumps mtime, which feeds base_score recency — selecting a try boosts its future ranking. That feedback loop is a feature, not an accident.

script_clone

script_clone (try.rb:1419-1421). Upstream hardcodes single quotes around the URI (git clone '#{uri}') instead of q() — preserved.

script_delete

script_delete (try.rb:1434-1439): cd into the base, test -d guard per basename, then restore the original PWD with a base-path fallback.

script_mkdir_cd

script_mkdir_cd (try.rb:1415-1417).

script_rename

script_rename (try.rb:1459-1467).

script_worktree

script_worktree (try.rb:1423-1432). The inner sh -c guard adds the worktree (detached) only when inside a work tree and always exits 0, so a non-git source still mkdir+cds. repo = None is the current-directory variant (no -C); src is what the echo names.
