Preparation requires an explicit closed run list from .local/state-group-gates. Preserve failed desktop-1 alongside accepted unchanged runs. Exclude core-1 from this package: its false unchanged-input flag and one map/archive mismatch belong in the separate pinned incident. Neither failures nor incidents are passes.

Example check-only invocation (extend with every subsequent closed run):

python -B prepare.py --root CHECKOUT --runs desktop-1 core-2 desktop-2 --check-only

Only after all selected captures close, omit --check-only and provide --output CHECKOUT/harness/experiments/state-multiselect-20260923/checks. Historical helper copies may be passed via repeatable --helper PATH. No existing output is overwritten. Run python -B verify.py PACKAGE for readback.

The strict verifier is unchanged from the ordinary multiselect package: exact seven raw files, helper bytes, safe archive inventories, all input-map/archive bytes equal, receipt relationships and inputsUnchanged exactly true are required. Failures retain their actual exits and streams. Source capsules preserve local historical bytes; recorded HEAD alone does not identify those bytes.

The earlier 733-input helper omitted the core compile-time integration fixture harness/experiments/edge-attachments-20260922/native-fixture.arcadia and the CLI fixture harness/experiments/textual-authoring-20260911/alarm-response.arcadia. Lint-1 failed, and its all-target capture additionally has a source-capsule scope limitation for the core fixture. Later 735-input captures add both explicit inputs. Desktop/core example captures retain their actual tested scope; do not infer that one map establishes a later map or complete all-target source identity.

Offline pin/receipt consistency is not test execution, authentication, native acceptance, or proof of usability. Executables and toolchains are not distributed.
