A directory can review repositories other than itself: a workbench whose
config, env file and records serve several, freezing each with --repo and
--out. The run took the working directory for the repository under review:
the prompt named it, the calibration was kept under it, and --trees fell
back to it. The run now reads the repository from the artifact's
freeze.json - the prompt names it and the calibration is kept under it -
and --trees defaults to what the record says: the worktree, else the
repository when it is not the working directory, else `.`, the same rule
that builds the printed run line. The working directory keeps its roles:
the config, the env file, the slots, the lens processes' cwd and every
logged path. A damaged record stops the run at preflight.
