 # Changelog
 
+## v0.41.0 — 2026-09-21 13:26
+- **Queue UI fixes (ISS-077).** Three queue-related map/UI fixes, no server logic changed:
+  - **Would-409 controls are disabled.** The on-board "Fly to …" button (`components/LeftPane.tsx`) is additionally disabled while the plane is flying and its destination is already active or queued (title "Already in flight queue"); the Relocate section disables its GO button for the same reason AND renders the selected plane's active/queued airports as native disabled `<option>`s. Grounded planes are untouched — their clicks go to `/fly`, which has no such conflict
+  - **Hover trace starts at the landing airport.** Hovering an on-board package while its carrier is FLYING now traces from the carrier's LANDING airport (`destIcao`), not its live mid-flight position (`components/Map.tsx`) — the hover previews what happens AFTER this leg lands; the solid active-leg + dotted queue layers already show where it is. Grounded / no-active-leg carriers keep today's behavior exactly (live position = the plane's airport). `hoverTraceGeoJson` returns an empty collection when start == dest, so a package destined for the active leg's destination draws nothing there — the solid layer covers it
+  - **Grounded queues draw dotted lines.** `queuedRoutesGeoJson` (`lib/mapData.ts`) now also draws GROUNDED ('available') planes with a non-empty queue, chaining from their current airport (`locationIcao → queue[0] → …`); flying planes keep the `[destIcao, ...queue]` chain; 'repairing' planes draw nothing. Same source/layer — no new MapLibre layer
+- **Tests.** Unit: `lib/mapData.test.ts` pins the grounded chain (exact endpoints), the unknown-first-point skip, the repairing skip and the start==dest empty trace; all flying-case pins stay green. E2E: `e2e/hover.spec.ts`'s mid-flight test is reworked — a package destined for a QUEUED stop beyond the active leg, hover traces from the landing airport to that stop with no segment starting at the departure airport (deterministic: paused right after dispatch); new `e2e/queue.spec.ts` test pins the grounded two-leg chain HUB → DEST → QUEUE in the `queue-routes` layer
+
+## v0.40.0 — 2026-09-21 13:06
+- **Top-bar version link (ISS-080).** The header's version tag (`components/Map.tsx`) is now an anchor to the repo's `CHANGELOG.md` on Gitea (`app-version` testid, opens in a new tab); one small CSS rule keeps it subtle against the dark header. E2E: `e2e/map.spec.ts` pins the exact href
+- **On-board ICAO tags (ISS-081).** The on-board package row in the fleet list (`components/LeftPane.tsx`) shows 4-char ICAO tags instead of full airport names — both the route span (new `onboard-route-{id}` testid) and the "Fly to …" button label + title. Other name displays (in-flight leg, plane location, map popup, open-package rows, toasts) are unchanged. E2E: one new assertion in `e2e/actions.spec.ts` pins the ICAO route on a loaded package
+
+## v0.39.0 — 2026-09-21 12:02
+- **Maintenance (ISS-069).** Planes wear out and can be repaired: distance-based health, a broken state that burns more fuel, and a repair action that grounds the plane for 3 sim days. New balance constants in `lib/game/catalog.ts` (all ponytail-tunable): `WEAR_PER_KM = 0.005`, `BROKEN_BURN_MULTIPLIER = 1.5`, `REPAIR_COST = 1_500` (flat), `REPAIR_DURATION_MS = 3 × 86_400_000`, plus the pure helper `conditionBurnMultiplier(health)` — exactly 1 above zero health, ×1.5 at/below it
+- **Schema.** Two new `planes` columns in all four places: Drizzle schema (`lib/db/schema.ts`), raw DDL + guarded `ALTER TABLE … ADD COLUMN` migrations in `migrateColumns()` (pre-existing rows backfill to full health / NULL gate, mirroring the weight_kg/special precedent), and the seed insert path — starter plane in `buildSeed` (`lib/game/seed.ts`) and every `buyPlane` delivery start at `health: 100`. New plane status `'repairing'` added to the three pinned unions (schema enum, `PlaneState`, OpenAPI) plus `mapData.ts`'s feature props
+- **Wear.** At landing only — `deliverPackages` (`lib/sim/engine.ts`) drops health by `WEAR_PER_KM × distanceKm` per landed leg (clamped at 0), in both the grounded and auto-chain write branches. A broken plane is one with `health ≤ 0`: it still flies, but burns ×1.5 more fuel — applied as a third factor alongside wind at ALL FIVE burn sites that hold the plane row: `flyPlane` dispatch feasibility + `refuelPlane` forFlight requirement (`lib/game/actions.ts`), engine landed-fuel + auto-chain next-leg check (`lib/sim/engine.ts`), and the live in-flight gauge in `livePlane()` (`lib/game/state.ts`). The engine's landed fuel uses the PRE-landing health (frozen at departure, like fuel) so it stays bit-consistent with the UI gauge; the chained leg's feasibility uses the post-wear value
+- **Repair.** New action `repairPlane` (`lib/game/actions.ts`) + POST `/api/planes/{planeId}/repair` (no body): 404 unknown plane, 409 not grounded ("only grounded planes can be repaired"), free no-op at full health (mirrors refuel), else charges the flat `REPAIR_COST`, restores health to 100 and grounds the plane in `'repairing'` with a gate at `clockMs + REPAIR_DURATION_MS`. The engine's new `finishRepairs` pass (same shape as `expirePackages`) runs inside every advancing tick — even when nothing landed — flipping gated planes back to `'available'` and clearing the gate. While repairing, the existing `status !== 'available'` guards in load/fly/refuel/sell/abandon block everything automatically
+- **Snapshot & OpenAPI.** `PlaneState` gains `health: number` + `repairUntilSimTime: number | null`; the repair endpoint is documented (200 → snapshot, 404/409). Pins updated in lockstep: `lib/openapi.test.ts` (fourteen endpoints, nine action-endpoint loop with errorCodes `['404','409']`, PlaneState key list) and `e2e/api.spec.ts`
+- **UI.** The fleet rows (`components/LeftPane.tsx`) show an amber health bar (new `.health-bar`, modeled on `.fuel-bar`) + a `{n}%` readout next to the fuel text; grounded planes get a red "broken" pill at zero health and an amber "in repair" pill while the gate runs (`.status-broken` / `.status-repairing`). A Repair button appears for any grounded plane below full health — no cost preview, flat cost is server-side only
+- **Test hook.** POST `/api/test/set-health` (`FLIGHT_TEST_HOOKS=1` only): `{ planeId, health?, repairUntilMs? }` forces a plane's health (finite in [0,100]) and/or sets its repair gate to `clock + repairUntilMs` — lets e2e force the broken state and shorten an active 3-day gate without flying thousands of km
+- **Tests.** New unit tests: wear accumulation per landed leg + clamping at 0 across multiple legs; broken-state ×1.5 landed fuel vs a healthy control on the identical leg; `conditionBurnMultiplier` pins; `flyPlane` feasibility using the adjusted requirement (same tank flyable at full health, 409 when broken); `repairPlane` (exact cost/status/gate/health, free no-op, 409s for flying/repairing/insufficient funds, load/fly/refuel/sell all blocked while repairing) and `finishRepairs` (gate boundary + flip-back through a full `tickOnce` with nothing landed). E2E: new `e2e/maintenance.spec.ts` — the visible flow per the issue (force 42 → UI shows it; force 0 → broken pill + short full-tank leg lands with exactly the ×1.5-adjusted fuel from the real lib helpers; click Repair → exact cash drop + "in repair" pill; shorten the gate via the hook → back to service at health 100), restoring a clean starter on exit
+- **E2E drift mitigation.** Wear accumulates across the whole CI run (one shared DB, workers:1) — the self-heal helpers in `e2e/right-pane.spec.ts` (`flyHomeViaApi`), `e2e/two-planes.spec.ts` (`resetFleet`) and `e2e/actions.spec.ts` (`flyHomeViaApi`) now restore full health + clear any active repair gate first, so the farthest-flyable pickers and the FAR round-trip feasibility pin never see a worn or broken starter
+
+## v0.38.0 — 2026-09-21 10:47
+- **Reputation economy (ISS-072).** Reputation is no longer a dead stat — it drives the economy through three simple tunable formulas, all built on one new pure helper `repRate(reputation, perPoint, cap)` in `lib/game/catalog.ts` (linear above the starting value of 10, capped; exactly 0 at/below start so default-rep behavior is byte-identical):
+  - **Cheaper plane purchases** — `buyPlane` (`lib/game/actions.ts`) charges `price × (1 − repRate(rep, PLANE_DISCOUNT_PER_REP = 0.01, MAX_PLANE_DISCOUNT = 0.4))`, rounded to 2dp; the effective cost drives both the funds check and the deduction (up to 40% off at rep ≥ 50)
+  - **Cheaper refuel** — `refuelPlane` multiplies ONLY the price term: `liters × FUEL_PRICE_PER_L × (1 − repRate(rep, FUEL_DISCOUNT_PER_REP = 0.005, MAX_FUEL_DISCOUNT = 0.2))`; burn/target math (wind factor, ×1.5 forFlight margin) untouched
+  - **Better jobs at higher reputation** — `generatePackage` (`lib/game/seed.ts`) takes an optional `reputation` input (defaults to the starting value) and multiplies the final reward by `1 + repRate(rep, JOB_BONUS_PER_REP = 0.01, MAX_JOB_BONUS = 1.0)` at the same spot as the special multiplier (base × jobBonus × special, single round at the end; up to ×2 at rep ≥ 110). Consumes NO extra RNG draw
+- **Spawn sites carry live reputation.** `spawnOpenPackages` + `spawnCoveragePackages` (`lib/sim/engine.ts`) read the account row once per spawn batch and thread its reputation into `generatePackage`; the test hook POST /api/test/create-package does the same (hook-created packages get current job quality, never a forced value). `buildSeed` keeps defaulting — no rep at seed time
+- **UI shows the effect.** The market buy row (`components/RightPane.tsx`) previews the EFFECTIVE price computed client-side from the snapshot's reputation + the imported constants, with a sky-blue "−N%" pill (`market-buy-discount`, reusing `.special-badge`) when the discount is non-zero; tech-spec cards keep showing full list prices. The left-pane Refuel section (`components/LeftPane.tsx`) previews the discounted fill-up cost with its own `refuel-discount` pill. No new snapshot fields — rep was already in the state, so the OpenAPI schema is unchanged
+- **OpenAPI (descriptions only).** buy-plane + refuel endpoint descriptions mention the rep-scaled discounts; `CatalogEntry.price`, `StateSnapshot.fuelPricePerL` and `AccountState.reputation` gain notes that the discount applies at purchase/refuel time. No properties or endpoints added/removed
+- **Tests.** New unit tests: `repRate` (zero at/below start, linear mid-range exact values, cap clamping), `buyPlane` at rep 30 (exact discounted cash delta + funds boundary between discounted and full price), `refuelPlane` at fixed rep in both 'full' and 'forFlight' modes (discount on the price term only), `generatePackage` job bonus (×1.5 at rep 60, default-rep byte-identity, composition with the special multiplier, no extra RNG draw). All existing unit tests pass unmodified — at the starting reputation every rate is exactly 0. E2E: the full-price pins in `right-pane.spec.ts`, `two-planes.spec.ts` and `actions.spec.ts` now compute expectations from the LIVE snapshot's reputation via the imported helpers (rep accumulates across specs), plus a new assertion that the buy-row discount pill appears iff live rep > starting with text round(rate × 100)
+
 ## 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
