 ## Immediate implementation and acceptance

+1. Preserve the verified creation integration and matching GUI stage, committed
+   as 4bb4aaf and transferred with independent anonymous readback/hash verification. Final immutable
    desktop653/653 passed after creation ancestry/guide changes, alongside focused
    creation21/guide3. StrictClippy/fmt pass after a behavior-equivalent history
    rewrite; affected history63 and GUI build also pass. Preserve exact artifact
    scopes and serialize future Cargo/source leases.
-2. Natively test the independently reviewed local creation workflow: explicit
-   names/viewpoints/owners, source/property draft retention, SA recovery, first
-   Escape and exact source/selection/Undo. Address actual task friction.
+2. Named process/scenario/machine creation, exact Undo/Redo and nine-file reopen
+   have passed at actual minimum size. Wide/minimum cancellation passed; SA draft
+   crash recovery is active. Address observed blank canvases and prerequisite
+   creation detours through the staged-source plan: source subform retains the
+   parent draft and final adoption atomically creates prerequisite and consumer.
+   First slice covers Lifeline, process Work and machine owner, with semantic
+   first-action prompts. Independent review precedes final integration/native QA.
 3. Operate the rebuilt app at minimum/normal sizes. Complete the saved basic
    supplementary move/camera/invalid-draft and minimum-size story; the main basic
    model and explicit transition passed full Project+SourceBundle, Undo/Redo and
