 # Changelog
 
+## v0.37.0 — 2026-09-21 09:29
+- **Special jobs: data-driven special-status registry for packages (ISS-073).** New `lib/game/specials.ts` holds a flat `SPECIALS` record (`special status → { rewardMultiplier, deadlineScale, repBonus }`) in the same house style as `PLANE_TYPES`, plus `SPECIAL_SPAWN_CHANCE = 0.15` and a pure `pickSpecial(rng, registry?)` helper (one chance draw, then a uniform pick among the registry's keys; the registry is a param defaulting to the real one). Adding or removing a special is an edit of ONE registry entry — no scattered branches. First status: **priority** (×1.5 reward, ×0.5 deadline window, +0.5 rep at delivery; all balance-tunable)
+- **Spawn & modifiers.** `generatePackage` (`lib/game/seed.ts`) appends one RNG draw at the END of its fixed order to roll a special (~15% of packages); a forced `special` input (including explicit null) skips the draw, mirroring the other overrides. The reward multiplier applies where the reward is computed; the deadline scale applies only to the drawn 6–72h window — a forced `deadlineOffsetMs` skips scaling
+- **Rep bonus at delivery.** `deliverPackages` (`lib/sim/engine.ts`) adds the registry's flat rep bonus on top of the distance-based gain for special packages, keeping the existing double-rounding convention (gain rounded to cents, total re-rounded)
+- **State shape & DB.** `special: string | null` added in all four places — `SeedPackage`, Drizzle schema (`lib/db/schema.ts`), raw DDL and a guarded nullable `ALTER TABLE … ADD COLUMN special TEXT` migration in `migrateColumns()` (pre-existing rows stay NULL = none, mirroring the weight_kg precedent), and `PackageState` + its row mapping
+- **UI badge.** Open-package rows (`components/RightPane.tsx`) and on-board rows (`components/LeftPane.tsx`) show a sky-blue "Priority" pill next to the route when the package has a special status (new `.special-badge` class, `package-special-{id}` testid); label via new `formatSpecialLabel` in `lib/format.ts`
+- **Test hooks & spec.** POST /api/test/create-package accepts `special` (string or null; omitted → forced null so existing e2e reward/rep assertions stay deterministic — documented in the route header), and expire-package passes `special: null` explicitly. OpenAPI PackageState gains optional `special: string | null`
+- **Tests.** New unit tests: registry application (reward ×multiplier, deadline ×scale, rep bonus at delivery), pickSpecial distribution with a fixed RNG, forced-value draw skip, and removing an entry cleanly disabling the status; existing reward/deadline assertions scoped for special packages. E2E: new right-pane test forces `special: 'priority'` via the hook and asserts the row shows the "Priority" badge
+- **E2E self-heal hardening.** The `flyHomeViaApi` helper in `e2e/right-pane.spec.ts` now abandons any leftover loaded/expired package bound to plane-starter once it's back at EDDF (the "open packages render" test leaves a 4 t package on board, which made later hook-package loads hit the payload check), and both that helper and `e2e/slow-on-landing.spec.ts`'s equivalent now refuel-and-retry the repositioning flight when it fails on insufficient fuel (modeled on `e2e/two-planes.spec.ts`)
+
+## v0.36.0 — 2026-09-21 08:45
+- **Refuel-for-flight now buys 150% of the required fuel for the leg (ISS-071).** `refuelPlane` mode `'forFlight'` (`lib/game/actions.ts`) tops the tank up to `min(maxFuel, max(current fuel, 1.5 × required))` instead of exactly the requirement — a margin so burn variance doesn't strand planes at the far end. The "does not fit a full tank" 409 guard now compares against the weather-adjusted requirement (see below). No UI change: the per-leg Refuel button has no amount preview, and the left-pane "Refuel to full" row is unaffected
+- **Wind affects per-leg fuel burn ±20% based on departure weather vs route heading (ISS-070).** The deterministic per-airport weather (`lib/weather.ts`, FNV-1a seeded by ICAO — no dayKey, stable across polls/sessions) now feeds the fuel math: a new `windBurnFactor(windKt, windDirDeg, bearingDeg)` in `lib/sim/movement.ts` returns `1 + headwindKt/150` (exactly [0.8, 1.2] over the 2–30 kt weather range), and a new `initialBearingDeg(lat1, lon1, lat2, lon2)` in `lib/geo.ts` gives the great-circle heading of each leg. Every fuel call site applies the departure airport's factor to `burnPerKm`: `flyPlane`'s feasibility check, `refuelPlane` forFlight, the engine's landed-fuel + auto-chain checks (`lib/sim/engine.ts`), and the live in-flight fuel display — computed server-side in `getStateSnapshot()`/`livePlane()` (`lib/game/state.ts`) from airport coordinates, so no schema change. Fully deterministic: one factor per leg, a pure function of (ICAO pair, catalog)
+- **Tests & spec.** Unit tests added for both helpers and the ×1.5 expectation (computed in-test via the same helpers — no stale literals); e2e specs import the real helpers from `lib/` instead of mirroring the wind math (`e2e/right-pane.spec.ts`, `e2e/two-planes.spec.ts`, `e2e/actions.spec.ts`), and their "farthest flyable" airport pickers now require BOTH directions to fit a full tank under wind. OpenAPI: description-only updates (refuel endpoint + `burnPerKm` note)
+
+## v0.35.0 — 2026-09-21 02:26
+- **Job list shows cargo tonnage instead of count (ISS-066).** The open-package rows in the right pane's Jobs tab (`components/RightPane.tsx`) now show cargo as type + tonnage ("Mail 10.0t") via a new `formatCargo` in `lib/format.ts` — `(kg / 1000).toFixed(1) + 't'`, identical to the loadout display — instead of "type × count"; unit tests added to `lib/format.test.ts`; e2e assertion added to `e2e/right-pane.spec.ts` (the hook-created package is forced to 10 t and its row must contain "10.0t"). No server or OpenAPI changes — `weightKg` was already in the snapshot
+
+## v0.34.0 — 2026-09-21 01:26
+- **Duplicate queue legs rejected with 409 (ISS-065).** `queueLeg` (`lib/game/actions.ts`) now refuses to append a destination that is already in the plane's flight queue ("{icao} is already in the flight queue"), and — while the plane is flying — re-queuing the active leg's destination ("already flying to {icao}"). Previously the same route could be queued any number of times, producing pointless repeated/zero-length hops when landing auto-chains `queue[0]`. No UI or OpenAPI changes (the endpoint already documents error responses)
+
+## v0.33.0 — 2026-09-21 00:45
+- **Merged On board into the Fleet list (ISS-054).** The left pane's separate "On board" section is deleted; each Fleet row (`components/LeftPane.tsx`) is now the single per-plane block — status/fuel/loadout plus, when present, that plane's loaded/expired cargo rows (fly-to / refuel-for-flight / abandon + penalty preview) and its queue legs. The header shows "in flight" + the current leg for flying planes and the location ICAO when grounded; the empty "Queue" heading is no longer rendered (the sub-section renders only with ≥1 queued leg). All per-item testids unchanged (`onboard-package-*`, `fly-to-*`, `refuel-for-*`, `abandon-*`, `abandon-penalty-*`, `plane-leg-*`, `queue-leg-*`, `queue-cancel-*`); the removed one is `onboard-{plane.id}` (use `plane-{id}`). CSS: `.onboard-block .contract-row*` re-targeted to `.plane-row .contract-row*`; no server or OpenAPI changes
+- **E2E updates.** The four `onboard-{plane.id}` references now target the fleet rows (`e2e/hover.spec.ts`, `e2e/right-pane.spec.ts`, `e2e/two-planes.spec.ts`); `e2e/panes.spec.ts` no longer asserts an "On board" heading — it asserts the heading is absent from both panes
+
+## v0.32.0 — 2026-09-20 23:47
+- **Queue via fly-to and Relocate; dedicated queue-add input removed (ISS-053).** The flight queue no longer has its own entry point in the On board block (`components/LeftPane.tsx`): the per-cargo "Fly to …" button is now enabled for ANY plane state, and posts to `/api/planes/{id}/queue` instead of `/fly` when the plane is `flying` (grounded → `/fly`, unchanged); Relocate's plane list widened from grounded-only to ALL planes (`relocatable = state.planes`; Refuel keeps its own `grounded` filter), and `relocate-go` posts to `/queue` when the SELECTED plane is flying, else `/fly`. The queue-add select + "Add to queue" button (and the shared `queueAddDestIcao` state) are deleted; leg rows + cancel buttons unchanged. No server or OpenAPI changes — both endpoints already existed
+- **E2E updates.** `e2e/queue.spec.ts` test 1 now adds its queued leg via the Relocate section (selects plane-starter, which is flying at that point → `/queue`) instead of the removed queue-add control; `e2e/two-planes.spec.ts` "per-plane queues are independent" adds the starter's second leg via API POST `/api/planes/plane-starter/queue` (the starter is grounded there, so fly-to would start rather than queue). All `queue-leg-*` / `queue-cancel-*` assertions unchanged
+
 ## v0.31.0 — 2026-09-20 21:23
 - **Two-plane Load is one-click again (ISS-055).** The reported "can't load cargo with two planes at the same airport" was UX, not a server bug: `LoadControls` (`components/RightPane.tsx`) rendered a plane picker for ≥2 eligible planes whose Load button stayed DISABLED until a pick existed, while the single-plane path is one-click. The multi-plane path now PRESELECTS the first eligible plane (`effective = … ?? eligible[0] ?? null`; the select already bound to `effective?.id`), so Load is enabled and one-click whenever ≥1 plane qualifies — the dropdown still allows picking a different plane
 - **LeftPane queue testids scoped by plane id (ISS-055).** With two on-board blocks in the DOM the unscoped ids duplicated: `queue-leg-{i}` → `queue-leg-{plane.id}-{i}`, `queue-cancel-{i}` → `queue-cancel-{plane.id}-{i}`, plus the add control `queue-add-dest`/`queue-add` → `queue-add-dest-{plane.id}`/`queue-add-{plane.id}` (`components/LeftPane.tsx`). The shared pane-level destination pick is unchanged. `e2e/queue.spec.ts` locators updated to the scoped form (single-plane fleet, id `plane-starter`)
