5. A2–A5 Polish — ✅ shipped on V3 (stamp a2-a5-polish-v1)

New Gravship Linking (G1–G9) — done

G1–G9 shipped on V3. MultiFloors lesson: explicit travel entitlement + deterministic shaft identity — not endless orphan heuristics.

1. G1 One engine of record — ✅ Pin travelling stack to the packed ship’s engine thingID at takeoff; never PreferBestEngine / CurrentMap fallback during land rebind.
2. G2 Stable shaft identity — ✅ Persist stack GUID + per-shaft ID so land never spawns a second “New” underdeck when packed stairs replace temp shafts.
3. G3 Substructure-ready land gate — ✅ Never CompleteLanding footprint rebuild until host ValidSubstructure (or VGE foundation proxy) is non-empty; single deferred sync path.
4. G4 Explicit travel entitlement — ✅ Host shaft Comp “Travel with ship” toggle gates launch follow.
5. G5 Multi-shaft wiring table — ✅ Restore by shaftId table; no best-match salvage when ID present.
6. G6 Shaft as grav-extender — ✅ Shaft footprint + rim owns the vertical pocket column for linked placement.
7. G7 Pack A+/B+ into Gravship cargo — ✅ MVP: pack buildings/items engine-relative at takeoff; place at land root (skip live-pocket align when cargo placed).
8. G8 Land polish — ✅ Orphan adoption, duplicate cull, deck cargo / footprint clear (with later force-wipe for non-destroyable elevators).
9. G9 Mid-flight underdeck view → land RGB — ✅ block viewing travelling floors mid-flight; land paints with host as CurrentMap + MapDrawer regen (stamp g9-travel-view-rgb-guard-v1).

Polish (A1–A5) — done

1. A1 Live see-through roof view — ✅ draw the map below through Strata_OpenSky / see-through Strata_RoofDeck (terrain, MapMesh things, live pawns); weather sync; click-select + double-click select-similar + forbidden overlays; float menu; cross-level ranged combat (pawns/turrets/mortars). Stamps see-below-v1 → below-select-parity-v1, cross-level-combat-v2, weather-sync-v1, roofdeck-seethrough-v1.
2. A2 Mental breaks that cross stairs — ✅ binge food/drug stash hunt + berserk / murderous rage chase through shafts (stamp a2-a5-polish-v1).
3. A3 Raider divert polish — ✅ pursue when no fightable colonists remain on this floor (downed-only does not hold them); chase toward linked floors with live colonists.
4. A4 Vertical utilities as one net — ✅ tankless pockets (no local batteries) still get offline demand + consumer bootstrap from shaft surplus even in performance mode.
5. A5 Per-system kill-switches — ✅ StrataFaultGuard auto-disables work relay / atmosphere / shaft fluid / robot soft-compat after repeated errors; shaft fluid toggle in settings.

More UX changes (M1–M10, no M5) — done

Shipped on V3 (merged from V3-M-ux).

1. M10 Level-switch Update OOR / flicker — ✅ clamp stale CurrentMap index after pocket create/destroy; harden overlay + Work/Schedule lists (stamp m10-level-switch-oor-v1).
2. M9 Gravship pilot seat from other floors — ✅ pawns on a linked underdeck / tower deck can fill the pilot role and right-click Pilot Gravship (stamp m9-pilot-across-levels-v1).
3. M1 Hospitality / guest / trader pathing — ✅ visitors rest/follow lord through shafts; exit-map escape already covered.
4. M2 Vehicle Framework — ✅ soft-compat: RoofDeck park / OpenSky blocked when VF hooks match.
5. M3 Modder API — ✅ Strata.StrataModderApi facade (reachable maps, stairs, link listeners, incident policy).
6. M4 Depth dim slider — ✅ optional upper-deck screen darken (settings).
7. M6 Medical bed preference — ✅ pin medical bed + FinishMedical LayDown on arrival.
8. M7 Reinstall buildings — ✅ WorkGiver_InstallAcrossLevels for minified → linked Blueprint_Install.
9. M8 Float-menu / caravan selection — ✅ linked-floor float menus + cross-level caravan sendables.
