+## 9 October 2026 — owned Sandmaster ground-movement pile selection
+
+The shared ground quote now groups all positive pile keys by entered
+territory. The owner can select either sector or decline collection;
+authoritative validation rejects two selected piles from one territory
+before any physical movement or spice transfer. Human and minimal legal
+AI defaults select at most one per group. The obsolete singleton helper
+is removed; native HMS retains its separate unambiguous-pile scope.
+Worm and physical Ambassador destination controls are unchanged.
+
+Basic and Advanced runtime smokes choose South Mesa5 rather than4,
+leave sector4's four spice untouched, collect one there and one in Cielago
+East, and move three forces. Personal spice10→12; South Mesa5 ends1 and
+Cielago East3 ends3. All four profiles emit legal collected-route candidates.
+Chromium at390px exercises switching, full-territory opt-out and reselection,
+then observes the same engine result with document width390/no overflow.
+This is isolated production-component/engine proof, not deployed acceptance.
+Owner allocation is visibly provisional; no publication gate is opened.
+
+Frozen verification: `check:quick` and all 21 affected movement, control
+and worm cases pass. Incidental HTML-attribute-order/default-action pins
+were removed rather than re-pinned; the retained control regressions
+exercise actual force movement, spice debit and unavailable-seat/profile
+boundaries. Temporary UI scripts/service were removed. No broad suite,
+recovery campaign or deployment was run.

+## Owned ground-route pile selection — 9 October 2026
+
+Ordinary ground movement now offers every existing positive pile in each
+entered territory. The owner selects at most one pile per territory, or
+declines that territory's collection. Choosing another pile deselects the
+previous one; clearing the selected checkbox declines the whole territory.
+The source grants one spice per territory but does not specify the debit
+sector, so owner selection is explicitly a provisional allocation policy.
+
+The shared `sandmasterCollectionPiles` quote groups offered keys by entered
+territory. Human controls and legal AI start with one deterministic choice
+per group; authoritative validation rejects two selected sectors from the
+same territory before forces or spice move. Signed original route and pile
+receipts retain their existing continuation behavior.
+
+Both mode engine smokes choose South Mesa sector5 instead of sector4,
+collect once there and once in Cielago East, preserve the unselected pile,
+and move three physical forces. All four profiles produce legal collected
+routes. An isolated 390px Chromium control smoke switches the sector,
+declines/reselects the territory, and commits the same move: personal
+spice10→12, South Mesa4 remains4, South Mesa5 becomes1, Cielago East3
+becomes3, and three forces arrive in Cielago East.
+
+Worm/physical-Ambassador destination choices and native HMS relocation
+retain their separate single-pile scope. No public start or broader
+source adjudication is opened by this ground-route change.
