Development record

.abcd/development/brief/06-delivery/01-build-sequence.md:62 says six further forms of `ahoy` write: `uninstall`, `remote apply`, `connect`, `credential --home`, `worktree add` and `worktree prune`. `abcd ahoy shared-folder <folder>` is a seventh: it writes `shared-folder.json` in abcd's home folder (internal/core/runstop/runstop.go:344-360), and .abcd/development/brief/04-surfaces/01-ahoy.md:34 lists it as shipped.
