 - **Shared action runner hook.** RightPane's local `runAction` (busy gate, inline pane error + shell toast on failure, full post-action snapshot pushed via `applySnapshot`) extracted to new `lib/useGameAction.ts`: `useGameAction(state, applySnapshot, onError) → { runAction, busy, actionError }`, exact semantics kept incl. the non-2xx throw/catch and inline-error auto-clear on the next snapshot. Used in BOTH panes; LeftPane receives `applySnapshot` from the shell (`app/page.tsx`). RightPane keeps `[data-testid="right-error"]`; LeftPane gains a matching `[data-testid="left-action-error"]`. Pure helpers `slotsUsedFor` / `loadEligiblePlanes` stay exported from RightPane (unit tests import them there; LeftPane imports `slotsUsedFor` from it); the Market Relocate row + `/api/airports` fetch stay in RightPane
 - Tests: e2e — `panes.spec.ts` first test now also asserts the "On board" heading is visible inside `[data-testid="left-pane"]` and absent from the right pane; stale header comments updated in `actions.spec.ts` / `right-pane.spec.ts`. No unit-test changes (baseline 283)
 - Verified: `tsc --noEmit` clean; unit suite green locally; e2e not run locally by design — CI verifies against an isolated stack
+- **On-board cargo rows are two lines (ISS-028).** Each `onboard-package-*` row now stacks a full-width "Fly to <airport>" button on its own line above Refuel + Abandon side by side: `components/LeftPane.tsx` moves the fly-to button out of `.contract-main` into the row root and wraps refuel-for + abandon in a new `.onboard-actions` div — all testids, label text, penalty preview and disabled states unchanged. Long destination names in the fly-to label truncate with an ellipsis instead of overflowing: the label's inner span gets `min-width: 0; overflow: hidden; text-overflow: ellipsis; white-space: nowrap`, full name preserved via a `title` attribute (CSS in `app/globals.css`: `.onboard-block .contract-row` becomes flex-column, new `.onboard-fly-btn` / `.onboard-fly-label` / `.onboard-actions`). No e2e changes — specs locate everything by testid and assert no layout or button order; no version bump (part 2 of v0.20.0)
 
 ## v0.19.0 — 2026-09-19 18:05
 - **Auto-slow to 1× when all planes have landed (ISS-011).** When the last plane in flight lands, the sim slows down on its own so an idle fleet doesn't sit at 1000×. Server-side and authoritative: `tickOnce` (`lib/sim/engine.ts`) now remembers how many planes `deliverPackages` finalized during a tick, and when ≥1 plane landed this tick AND no plane remains with status `'flying'` AND the sim is not paused, it persists `timeScale = 1` on the same `sim_state` write as the clock — so the UI slider reflects it on the very next snapshot (no API or OpenAPI change: timeScale is still set via the existing `POST /api/sim`, and `clampTimeScale` semantics are untouched since 1 is a valid ladder value)
