Running scripts/install.sh from a checkout linked `dsh` straight at that
checkout, producing an install that `dsh-upgrade` cannot upgrade (there is
no `current` to repoint), that dangles if the checkout moves, and whose
launcher resolves to an arbitrary working branch.
In-repo mode still never clones and never touches the working tree, but it
now offers to adopt the checkout, and adoption is the default. The container
owns staging worktrees and `current`; the repository is discovered via
`git rev-parse --git-common-dir` rather than owned, so a clone anywhere on
disk converges on the same upgradable layout as a curl install and both
share one worktree/exclude/lock/link sequence.
Declining, or DSH_ADOPT=0, keeps the previous link-in-place behavior with a
warning naming what it costs, preserving the path that makes this script
testable against local source.
All path comparisons run on physical paths: macOS resolves /var through a
symlink to /private/var, and comparing a resolved path against an unresolved
one misclassified an existing managed install as a foreign clone.
Verified manually (no install.spec.ts, per request) with a harness driving
the real script under a stubbed pnpm across 33 assertions, plus both
interactive outcomes under tmux.
Squashes feat/personal-config-dsh-home: personal config.yaml and .env move
from ~/.config/dsh to the Harness home (~/.dsh), plus the module-graph,
lockfile, and i18n pairing regeneration that followed.
Squashes feat/install-script, feat/install-default-master, and
install-skip-clone: DSH_REF defaults to master, and running the script from
inside an existing checkout reuses it and skips the clone.
