+- **Job payoff retuned so weight dominates (ISS-090).** `REWARD_PER_KG` in `lib/game/seed.ts` rises from €0.5/kg to €2.0/kg — the linear form is unchanged, only the constant moves. Before, the weight term was small vs base+distance, so heavier jobs barely paid more (a 1000 km leg: €3,250 @500 kg → €5,000 @4,000 kg — per-kg rate fell from €4.59 to €1.01) and there was no sense in taking heavy jobs; after the retune the same leg pays €4,000 / €11,000, so weight clearly drives payoff. Safe for viability: fuel burn (`lib/sim/movement.ts`) is weight-independent, so this only raises income
+- **Tests.** `seed.test.ts`: stale test name "… 0.5 * weightKg …" made generic; new literal pins in the `rewardFor` formula test — `rewardFor(1000, 4000) === 11_000` and `rewardFor(1000, 500) === 4_000` — so future retunes are deliberate. All other reward assertions recompute through the exported constants and pass unchanged

 ## v0.46.0 — 2026-09-21 22:32
 - **Queue consumption on dispatch (ISS-088).** `flyPlane` (`lib/game/actions.ts`) now consumes `queue[0]` when the requested destination IS the first queued leg, so a landing never chains a zero-distance self-hop (the "phantom hop" — a→a completing instantly before reaching the real next leg). Flying to a non-first queued leg stays an explicit override and leaves the queue untouched; the persisted queue is written back in the same update
 - **Engine auto-chain hardening.** `deliverPackages` (`lib/sim/engine.ts`) gains two guards: (1) defensive skip — if `queue[0]` equals the arrival airport (only reachable from legacy/corrupt rows now that dispatch consumes), it drops the leg without flying; (2) full-tank backstop — if the next queued leg does not fit even a full tank, the plane grounds as `'available'` with the queue kept intact instead of chaining an unflyable leg (mirrors `flyPlane`'s 409 without throwing mid-tick)
