This is an offline evidence and source review, not combined-build or native acceptance. Delivery is 7e348d967d1787c052a145b7448636613a6a7054; final product source is f6a6010baed9e6164a1fcc7ecd58256a562827d7, following 12a7352ddef5f69a144ead8219a50916233d63a9 above State/attachment base b8685416f56e53e30bd11ecf93a54cea10ac8458. The reviewed integration target is f82e29d6b8ed2b5fd23ac806675d3eafe851d104.

The parent fetched the named delivery, read all three supplied verifiers, exported the exact committed package bytes, and ran those verifiers with Python 3 on Windows. All three exited zero. Raw result and exported-file pins and the three parent-verifier-*.log files retain the actual outputs. Paths in that result are historical machine-local labels, not handoff dependencies.

Checks package: 19 closed historical runs, 134 logical files, 114 stored members, and nine source-capsule pairs. Five historical nonzero runs remain failures.
Native package: two historical closed runs, 393 members, 27 and 24 captures, nine positive saved-state checks per run, and exact three-group source history.
Source identity: every captured input and the complete filtered inventory match the named Git trees for desktop-4 (12a7352, 729 inputs) and desktop-5 (f6a6010, 729 inputs).

These checks establish package consistency and committed-source identity. They do not rerun a compiler, archived helper, application evaluator, or GUI; they do not independently authenticate historical gestures. The parent also read the delivery's verification report. Its final desktop result is reported as 1,257 passed / zero failed / six ignored, distinct from the earlier layout-defective build. Native movement uses an inferred bounded common delta, and contextual Add is not native Shift-click evidence. Those limitations remain applicable.

The independent source/composition review finds no established production blocker in the scoped contribution. Integration must add layout: None to the new example's Diagram literal, retain the final fixed selection strip and the target's Scenario admission, Text writer, Properties actions, and saved-Scenario exclusions, then verify the combined behavior. The preview-cache ordering observation is a targeted regression requirement, not a demonstrated native bug. Full issue 29 remains open for other diagram families and aggregate model deletion; this audit does not change ownership or acceptance.

Reproduce the upstream audits from a checkout of the delivery containing its ancestor commits (the scripts themselves are versioned at that exact delivery):

python -B harness/experiments/multiselect-20260923/checks/verify.py
python -B harness/experiments/multiselect-20260923/native/verify.py
python -B harness/experiments/multiselect-20260923/source/verify.py --repo . --checks harness/experiments/multiselect-20260923/checks

Upstream verification report contains the original commands, scope, historical failures, native observations, and linked packages. The parent performed this audit without changing the active combined or private-analysis source under test. Linux remains user-deferred.
