itd-69 ac-1 and ac-2 promise a checker that runs with --tree public and --tree dev. Delivered: launch.CheckLockstep (internal/core/launch/lockstep.go:51) takes the tree as a Go parameter and has no front door — dry-run and ship call it with TreeDev over the source tree (internal/core/launch/dryrun.go:114, ship.go:80) and only the payload render calls it with TreePublic over its own output (internal/core/launch/render.go:444). A public checkout — a marketplace install, a release source archive — cannot be checked for manifest lockstep from the CLI or the plugin surface at all. Wanted: a read-only verb or flag that runs CheckLockstep with a chosen tree against a named root and exits with its 0/1/2 code.

Grounds

• pursued: a public checkout is checkable for manifest lockstep from the CLI and the plugin surface; shown wrong if launch manifests --tree public over a tree whose marketplace entry disagrees exits other than 1
