The builder's imported modules could mark an empty dependency tree as installed. Probe every anchor in one isolated target process. Require all anchors for a multi-module extra, and process only the selected tree's .pth files so editable packages retain their launch behavior. The native builder passes its staged Python explicitly and stops before manifest publication when the inventory fails. Correct the Hindsight and Teams anchors using the namespaces in their locked wheels. Verified: 31 tests passed, 3 host skips. A real target child records its identity, and a caller mutation back to the builder Python fails the regression. Both downloaded SDK wheels match uv.lock and pass inventory and availability checks. Ruff and added-comment checks passed. No full native package or signing run is claimed.
