Context
#16341 isolated three preview failures. The actual-pointer large-over-small popup witness can pass, then fail on a later isolated run at the same head. Its bounded poll times out before the parked source and one ready target-local proxy/preview/indicator set coexist.
Closed #16117 / PR #16137 repaired the earlier non-coverable target-cover path. This intermittent successor stays separate; the current evidence does not yet identify whether park admission, claim replay, or target embodiment loses the gesture.
The Problem
A geometrically valid partial overlap can fail to materialize the popup conversion before target selection. Final receipts may remain absent even though both live rects, overlap thresholds, and pointer intent were established.
The Fix
Use the witness's existing failure diagnostic to compare the last sensor/claim, lastVesselParkReceipt, parked geometry, coordinator lease, and target DOM census across passing and failing runs. Repair the first owner whose state diverges. Do not extend poll time or add pointer wiggles as the fix.
Acceptance Criteria
Out of Scope
- #16341 tour/indicator/toolbar repair
- Same-gesture re-entry/re-exit coordinates
- #16356 fixed-stage zero-rect frame
- #16353 grid repaint after splitter drag
Decision Record impact
depends on ADR 0029 §§2.8.2–2.8.6; revalidate only if the measured owner contradicts the recorded target-cover lifecycle.
