Does this layout's harness READ this repo-relative path — "is it mine?"
The ONE answer behind every adapter's claims, so an adapter cannot express a
claim its own layout contradicts. Pure: a string question about a string, with
no filesystem and no knowledge of what else exists.
The
claims(path)helper every shipped adapter uses: derive "is this path mine?" from the adapter's ownPluginLayout, so a layout that moves takes its claim with it. Overrideclaimsby hand only for a location the layout fields cannot express. Seecore/surface-discovery.tsfor why a claim is a question about a PATH and never about a root.
