Context and problem
#18303 requires ordinary pointer actions to join the same multi-window history as other origins. The existing WorkstationHumanPopupOverlapNL size matrix converts out and cancels its incoming pane; its initial release only creates the Metrics target. It therefore does not persistently guard the later release into that existing popup and its undo/redo.
The parent acceptance receipt records a passing local probe. This is a test delivery, not a newly claimed product defect. #18428 / PR #18430 repairs the observation and restores the existing matrix; its approved scope stays frozen.
Architectural reality and fix
Extend the existing E2E spec only. Share its ordinary pointer setup between the original restore terminal and a new commit terminal, retaining the four existing size combinations. Observe getWorkspaceDocument, pane identity, native lifecycle records and the Group's existing history. No production helper, wire format, dependency or gesture behavior changes.
The source popup is provisional: semantic transfer is main → existing popup. Native titlebar transfer between committed popup workspaces remains separate. Target positioning can append native-popup-move rows, so identify the incoming pane's dock-transfer row rather than counting every cursor increment as a drop.

| Pointer terminal and history |
Real pointer release, current documents, pane and native owners, Group rows |
Not committed while held; one two-participant transfer on release; undo and redo preserve pane identity |
Fail on early commit, wrong destination, duplicate DOM, retained source, or extra pane transfer |
Four headed size cases and cancellation control |
Acceptance criteria
Out of scope
Production changes, root-edge policy, theming, the second-independent-root case, CI enablement, and changes to #18430. Merge the reader prerequisite before publishing this standalone test PR against dev.
Decision Record impact: aligned with ADR 0029; no amendment or new module.
Prior art and ownership
Live latest-20 open issues and latest-30 all-state A2A messages checked immediately before creation (2026-09-07 02:23 UTC); no competing terminal-test leaf or claim. Exact all-state pointer-release search found the distinct first-terminal #18409 and readiness #18428. Seven own open issues checked; the two same-surface bodies are #18303 (parent acceptance owner) and #18428 (existing reader/restore repair). MC query pointer release existing popup undo regression coverage returned the parent probe receipt 685cfb83 and older native-park context, not another owner. Euclid takes this single test-only delivery.

dock-transferrow spans main and target; one undo visibly returns the pane to main, and redo visibly restores it to the existing target without adding history.Out of scope
