 # Changelog
 ## v0.64.0 — 2026-09-23 10:06
 - **Market keeps topping up while the fleet is grounded (#135 follow-up).** Root cause of a soft-lock introduced by v0.62.0's frozen clock: in `tickOnce` (`lib/sim/engine.ts`) every package-CREATION path (market top-up + coverage spawn) sat behind the same `advanceMs > 0` gate as expiry/delivery/repairs, while removal paths did not — `ignorePackage` runs on any request regardless of advance. A fully grounded fleet therefore froze the clock AND stopped all spawning, so repeated ignores could drain the market below `MARKET_TARGET_OPEN_PACKAGES = 10` (down to zero) and no code path ever created new jobs again: a player with a grounded fleet and an empty market was stuck forever. Fix: only the two spawn calls moved OUT of the gate — `spawnOpenPackages` + `spawnCoveragePackages` now run on EVERY tick, including frozen ones, passing the current (possibly frozen) `clockMs`; `expirePackages`, `deliverPackages` and `finishRepairs` stay inside it. Both spawns were already idempotent no-ops when satisfied (count-gated at target / set-gated by uncovered grounded airports), so advancing ticks behave exactly as before and the clock stays EXACTLY frozen while grounded — only new packages appear, created at game time. No schema change, no migration, no other engine behavior touched.
 - **Tests.** Unit: `lib/sim/engine.test.ts` — "a frozen tick still tops up the market so a grounded fleet never starves (#135 follow-up)": fully grounded fleet (advance=false), open market drained to zero via direct DB writes, one tick → asserts BOTH that `sim.clockMs` is unchanged (freeze preserved) AND that the open count is back at ≥ `MARKET_TARGET_OPEN_PACKAGES` with ≥1 open package originating at the grounded starter's airport (EDDF coverage). E2E: `e2e/sim.spec.ts` — "a grounded fleet never starves: ignoring every open package cannot empty the market (#135 follow-up)": self-heals to a fully grounded fleet, drains by calling `POST /api/packages/[id]/ignore` for every open package in repeated passes (pre-fix this reached zero and stayed there; post-fix each request's tick re-tops-up before its removal, so it can't), then `expect.poll`s that the open count from `/api/state` is above 0 within ~5 s of real time while asserting `simState.clockMs` stays EXACTLY equal to its pre-drain value and no plane took off — pinning both starvation-fixed and clock-still-frozen.
 ## v0.63.0 — 2026-09-23 08:43
 - **Overlay colors retuned for the Fiord default (ISS-118).** The first half of this issue landed in v0.4.0 (`DEFAULT_STYLE_ID = 'fiord'` + top-bar switcher, e2e already pins `toHaveValue('fiord')`); this completes the second half — auditing every color drawn on the map against Fiord's actual palette. Key finding: OpenFreeMap's Fiord is a DARK cool-toned basemap (land #45516E slate, water #38435C navy — verified byte-identical between the self-hosted `public/styles/fiord.json` and `tiles.openfreemap.org/styles/fiord`), not a light one. WCAG contrast audit of all nine overlay colors against both base surfaces: seven already read fine (≥ 3.3:1 on land AND water) and are untouched — amber flying leg #f59e0b, gold dotted queue line #d4a017 (ISS-098 picked it for light+dark), sky-blue grounded plane + hover halo #38bdf8, green flying plane #22c55e, yellow hover ring/trace #facc15, green target ring #4ade80. Two were weak and got brightened one step within the same hue family: airport dot fill rose-600 #e11d48 (1.68:1 on slate land — the weakest element on the map) → rose-500 #f43f5e (2.15:1), and the hovered-route highlight red-500 #ef4444 (2.10:1, below the 3:1 graphical-object bar for an emphasis layer) → red-400 #f87171 (2.86:1 on land / 3.57:1 on water). White strokes and all other paint values unchanged; no new constants — both colors are single-use inline paint values, matching the existing style of this file.
 - **Tests.** No test changes needed: `components/map.test.ts` pins only #d4a017 (untouched), e2e specs query rendered features by id/layer rather than color, and `lib/mapStyles.test.ts` already pins `DEFAULT_STYLE_ID = 'fiord'`.
 ## v0.62.0 — 2026-09-23 07:36
 - **Fixed 24x world clock (#135).** Finalized the closed issue #117 spec: the world clock runs at the fixed `WORLD_TIME_SCALE = 24` while any plane is flying or in repair, and stays FROZEN when the whole fleet is grounded — replacing v0.56.0's idle slowdown (`IDLE_WORLD_TIME_SCALE = WORLD_TIME_SCALE / 24`, ISS-128). **Production rate is now exactly 24x regardless of legacy stored values:** `tickOnce` in `lib/sim/engine.ts` computes `advanceMs = advance ? min(elapsed, MAX_TICK_ELAPSED_MS) × scale : 0` where `scale = FLIGHT_TEST_HOOKS === '1' ? sim.timeScale : WORLD_TIME_SCALE` — pre-v0.52.0 saves hold `timeScale: 1000` (the old UI ladder), which is why the live instance still ran at ×1000; only deployments with the env var set honor the stored override written by `POST /api/test/set-timescale` (range [1, 100_000], kept for tests). A frozen tick skips expiry/delivery/repair/spawn entirely and only updates `lastRealTickMs`, so resuming activity never fast-forwards the frozen span. The client mirror (`advanceSimClock` in `lib/useSimClock.ts`) holds its anchor value while grounded, so polls re-anchor without any jump. Removed: `IDLE_WORLD_TIME_SCALE` from `lib/worldClock.ts`, and — **separate finding** — `FLIGHT_TEST_HOOKS: "1"` from the production `docker-compose.yml`: it enabled the `/api/test/*` hooks in prod AND (pre-gate) made the live instance honor its stale stored 1000; e2e runs only in CI against `docker-compose.ci.yml`, which sets the var itself. Unchanged on purpose: the ~1 s background tick (started at boot), the test hook endpoint, and the inert legacy columns `paused`/`lastSelectedTimeScale` (nothing reads them; no migration — per #117 saves reset when multiplayer ships). The OpenAPI description of `/api/state` ("while no plane is flying or in repair the clock stays frozen") now matches the code.
 - **Tests.** Unit: `lib/sim/engine.test.ts` — both rate branches pinned: with `FLIGHT_TEST_HOOKS=1` stubbed (the file's default, like CI) stored overrides are honored; a new production test unsets the var and proves a legacy stored `timeScale: 1000` still advances at exactly ×24. Grounded-fleet tests pin a FROZEN clock (no idle creep, resume-without-catch-up after takeoff, raised timeScale ignored while grounded); describe renamed to "grounded fleet freezes the world clock (#135)" and pins `WORLD_TIME_SCALE = 24`. `lib/useSimClock.test.ts` — the grounded case asserts staying exactly at the anchor value. E2E: `e2e/sim.spec.ts`'s idle test becomes an exact freeze (delta === 0 after ~2.5 s of idleness); `e2e/state.spec.ts`'s restart test tightens from bounded delta to EXACT clock equality across `docker compose restart`; `e2e/right-pane.spec.ts` verifies the frozen clock, then asserts the abandon-penalty preview matches the server exactly (zero drift under a frozen clock — replaces the DRIFT_MS slope tolerance); `e2e/events.spec.ts` relaxes strict clock advance between SSE frames to non-decreasing (a grounded fleet pushes identical-clockMs frames; advance itself is pinned in sim.spec.ts). The activateWorld/deactivateWorld wrappers are unchanged — a repairing plane still means full scale.
 ## v0.61.0 — 2026-09-23 07:12
 - **Special remote airports (ISS-097).** The world dataset was curated to `large_airport` only, so genuinely empty regions — Antarctica, the high Arctic, Alaska, northern Canada and far islands — had no markers at all. New pure function `isRemote(airports, icao)` in `lib/airports.ts` (reusing the existing `haversineKm` from `lib/geo.ts`): an airport is remote when no other member of the given list lies within `REMOTE_RADIUS_KM = 1000`. The curation in `scripts/build-world-airports.mjs` now runs over ALL fixed-wing rows: every large_airport (unchanged clustering) plus every non-large row that is remote against the kept set; same-station twins (two strips <40 km apart at one base) collapse via the same greedy 40 km clustering. `data/airports_world.csv` grows from 1119 → **1483 rows** (+364 remote airports), including Rothera (EGAR), Halley (EGAH) and Showa skiway (AT25) in Antarctica; Grise Fiord (CYGZ), Alert (CYLT), Ny-Ålesund (ENAS — Svalbard's only marker within 1000 km of a large airport) and Wrangel Island (UHMZ) in the Arctic; Bethel (PABR) and other Alaska strips; Canadian-Arctic smalls; and far islands such as Easter (SCIP), Canton (PCIS), Henderson/Pago Pago (PMDY) and Ascension (FHAW). The only change to a pre-existing row is an upstream `home_link` refresh on CYLW. New airports become contract origins/destinations and map markers unchanged — the most isolated airport in the new set (Easter Island) has its nearest neighbour 2599 km away, well under the 9000 km job cap, so every origin stays flyable; `filterWorldAirports` already accepts small/medium/seaplane types, so no runtime change was needed.
 - **Tests.** Unit +4 in `lib/airports.test.ts`: a synthetic radius boundary (equator pair at ~945 km vs ~1052 km), real coordinates (Frankfurt↔Amsterdam is not remote; McMurdo vs Christchurch is), an unknown ICAO returning false, and the committed-dataset curation invariant — every non-large row has no large airport within 1000 km and at least one non-large row exists.
 ## v0.59.0 — 2026-09-23 05:48
 - **SSE frames no longer carry package history (ISS-133).** Measured on the live instance first: each `/api/events` frame was compact JSON at ~597 KB, pushed once per real second regardless of time scale (the background tick is a fixed 1 s interval; ×1000 just advances the clock further per frame) — and 99.8 % of it was `packages`: 1,521 rows because terminal packages are never deleted from the DB (expired 564, delivered 528, ignored 386, abandoned 31), while only 12 were `open`. No component ever reads a package with a terminal status — the market list renders `open`, and on-board cargo is `loaded`/`expired` (`LeftPane`, `cargoWeightFor`) — so the history was pure re-sent weight. New `sseFrame(snapshot)` in `lib/game/state.ts` projects a snapshot down to the client-rendered statuses (`SSE_PACKAGE_STATUSES = open|loaded|expired`); both SSE paths use it — the broadcast in `lib/sim/engine.ts` and the initial frame in `app/api/events/route.ts`, so a connect never costs one full-history frame. Live payload drops ~597 KB → ~10 KB per frame (≈ 60×), bounded forever by fleet/market size instead of growing with play time. `/api/state` and action responses keep the FULL package set unchanged, so every e2e oracle that asserts `delivered`/`abandoned` transitions via state lookups still works; the polling fallback stays a strict superset of what SSE pushes. Deliberately NOT done: hash-skip broadcasts (the snapshot's `clockMs` advances on every tick even while idle — `advanceMs = min(elapsed, 2000 ms) × scale ≥ 1 s` — so no two frames are ever equal), throttling (already exactly 1 Hz), and a diff/patch engine.
 - **Tests.** Unit +3 in new `lib/game/state.test.ts`: the projection keeps exactly open/loaded/expired (order preserved, terminal rows dropped), passes account/simState/planes through untouched without mutating its input, and pins the status set itself. E2E: `e2e/events.spec.ts` now records every package status seen in any frame plus the largest frame — asserts no terminal status ever appears and frames stay under 200 KB (a full-history regression at ~597 KB fails loudly).
 ## v0.58.0 — 2026-09-22 21:27
 - **Plane markers no longer teleport across the antimeridian (ISS-124).** The follow-up to ISS-120's known limitation: a plane mid-crossing still used the snapshot's wrapped lat/lon (`positionAt` wraps every longitude into [−180, 180]), so its marker jumped +179.x → −179.x between polls — a visible 360° teleport on the map while its route line stayed continuous. `planesGeoJson` in `lib/mapData.ts` now takes the airport index (`airportsByIcao`, same parameter shape as `routesGeoJson`) and re-expresses each FLYING plane's longitude against its departure airport — the same anchor `greatCircleArc` keeps for its first sample — via a new module-private `unwrapLon(lon, prev)` (the ±360 shift until |Δlon| ≤ 180 that `unwrapLons`'s loop body already used; `unwrapLons` now calls it). The unwrap applies only when BOTH leg endpoints exist in the index, mirroring `routesGeoJson`'s guard exactly: a marker is unwrapped if and only if its line is drawn. Grounded planes, repairing planes and flying planes with a missing endpoint keep their raw wrapped position (unchanged behavior); non-crossing legs are byte-identical (no |Δlon| > 180 → the shift never fires). `components/Map.tsx` passes `airportsIndexRef.current ?? new Map()` at both call sites (`applyDynamic` and the source bootstrap in `ensureLayers`) — planes draw immediately at their wrapped position until the airport index loads, then unwrap.
 - **Tests.** Unit +6 in `lib/mapData.test.ts` (new "antimeridian marker unwrap" block on the real NZAA/NFTF pair): eastward crossing unwraps a mid-leg −179.5 to +180.5 against the origin's +174.8, westward (reversed pair) unwraps below −180, and — the key invariant — every sample of `greatCircleArc(NZAA→NFTF)` fed back as a WRAPPED snapshot position comes out exactly on that arc's own sample, so marker and line agree frame to frame; grounded planes keep their raw coordinate, a flying plane with a missing endpoint stays wrapped (no line drawn either), and non-crossing legs are untouched. E2E +1 in `e2e/map-interactions.spec.ts`: the starter is relocated to Auckland via a fewest-legs chain over `/api/airports` (each hop ≤ 3400 km — within the ATR72's guaranteed range even in worst-case headwind; the tank is topped for free with the `set-fuel` hook before every dispatch so auto-refuel costs nothing), then a hook-created NZAA → NFTF package is loaded and flown at scale 1000 while the marker's longitude is sampled from the planes source every ~500 ms (real time) until the server reports landing — no two consecutive samples may differ by ≥ 180° (the teleport), some sample must sit on the east world copy (lon > 180, proving the crossing was actually traversed unwrapped rather than skipped), and the sampled span must exceed 4°. The plane chains back home afterwards so the other specs start from the canonical state.
 - **E2E fix (CI run 176).** The new antimeridian test failed deterministically in CI — not a marker bug, but a query trap: MapLibre's `querySourceFeatures` only returns features in LOADED tiles, and GeoJSON sources load per viewport tile; the default camera sits over Europe while NZAA/NFTF are in the Pacific, so the plane feature never appeared in queries and the "flying" poll timed out (the same pattern passes for EDDF→LEMD because that leg is inside the default view). The test now fits the camera over both endpoints first via `fitToAirports` (copied from `e2e/hover.spec.ts`, including its ISS-120 unwrap so a ±180-straddling pair bounds the Pacific, not the Atlantic) before polling and sampling. Pollution guard: relocation + crossing now run in a `try/finally` whose cleanup ALWAYS runs — it waits for any in-flight leg to land (scale 1000), then chains the plane back to EDDF from wherever it is, so a failed poll can no longer leave the starter FLYING and 409-cascade into the eleven later specs' fly-home helpers (the run-176 cascade). The dispatch POST's status is now checked explicitly with a clear message instead of a bare `expect(...).toBe(200)`. Unit +1 in `lib/mapData.test.ts` pins the exact feature properties the e2e `starterMarker` matches on (`properties.id === 'plane-starter'`, `properties.flying === true`).
 - **E2E fix (CI run 177).** The antimeridian test still failed — again not a marker bug: by dispatch time the test's page had been alive ~3 min through the relocation chain, and under dind load the browser's state feed can go stale (the SSE fallback in `lib/useGameState.ts` only re-arms polling on stream error or a one-shot 5 s silence check at connect), leaving the planes source frozen on an old FLYING frame from a relocation hop — which fooled the "wait for flying" poll and made every sampled longitude a stale pre-crossing value (continuous, all ≤ 180, never > 180). The test now reloads the page after relocation (server state persists; on the fresh page only the crossing leg can ever produce a flying frame), and the sampling loop gains a freshness gate: a sample is recorded only if its marker position is within ~700 km of where the SERVER snapshot says the plane is (~5 s of flight at ×1000 — haversine is ±360°-periodic in Δlon, so wrapped server lon vs unwrapped marker lon compare directly), so a frozen frame can no longer pass continuity vacuously; `starterMarker` now also returns latitude for that check. Pre-existing flake fixed in the same run: `e2e/queue.spec.ts`'s chain-refuel lower bound loosened from `1.4 × required2` to `1.3 × required2` — under dind load the post-departure snapshot can land ~0.1 × required2 into leg 2's burn (observed miss: 0.07 %); a wrong top-up level still lands far below the bound, and the exact level remains pinned by the upper bound plus the rep-discounted cash assertion.
 - **Root cause of the stale-feed freeze fixed in `lib/useGameState.ts` (CI run 178).** The reload + freshness gate above were insurance; run 178 proved the feed can freeze even on a FRESH page — and the reason is now fixed at the source, not worked around. The SSE silence check was one-shot: `setTimeout(startPolling, 5 s)` armed once at connect, cleared by the FIRST event and never re-armed. After that, only a stream ERROR could restart polling — but a half-open connection that simply stops delivering data (observed under dind load; `/api/state` on separate connections kept answering fine throughout) fires no `onerror`, so state froze until reload. The timer is now re-armed on EVERY message: any 5 s gap in the event flow — whenever it happens, not just before the first event — starts the polling fallback (immediate catch-up fetch + interval), which stops again when fresh events resume. Healthy streams pay one set/clearTimeout per event; stalled ones degrade to the pre-v0.57.0 poll loop instead of freezing. The e2e keeps both insurance layers: the reload still guarantees a clean SSE connect at dispatch, and the freshness gate still fails loudly if any future stall outlasts it (a frozen source can no longer pass continuity vacuously).
 - **Tests.** Unit +1 in `lib/mapData.test.ts` ("NZAA→NFTF crossing leg — full pipeline on stored dataset coords"): runs the exact production pipeline on the STORED CSV coordinates (`loadAirportsGeoJson` → `positionAt` slerp sampled at 51 steps → `planesGeoJson`) and pins what a live browser source must show — marker lons monotonically increasing from +174.8 to +184.9 (the unwrapped NFTF), every consecutive pair < 180° apart, max > 180 (eastward crossing onto the world copy). This is the ground truth the e2e's `lon > 180` assertion encodes: the dataset crosses EASTWARD (NZAA +174.786 → NFTF −175.149, Δ ≈ +10°), so a correct pipeline MUST produce lons above +180 — and any e2e failure of that assertion is now provably a stale browser source, not the math.
 ## v0.57.0 — 2026-09-22 19:19
 - **Push updated state to clients over SSE (ISS-129).** Clients no longer rely on pure polling for live updates: new `GET /api/events` streams full game-state snapshots as Server-Sent Events — the current snapshot immediately on connect, then one after every sim tick (~1 s), so the UI updates push-driven even while idle. New module `lib/sse.ts` is a tiny in-process fan-out registry (`subscribe(fn)` → unsubscribe, `broadcast(text)` with per-subscriber try/catch) — the three process-wide singletons (this subscriber set, the sql.js DB promise (`getGameDb`), and the tick lock (`withLock`)) live on `globalThis`: Next.js can load a module more than once per process (instrumentation.ts and route handlers get separate module instances), so plain module-level state would give each layer its own registry/DB/lock, and background-tick pushes would never reach route-handler subscribers. The broadcast hook lives in `tickNow()` in `lib/sim/engine.ts`: after each locked tick on the singleton path it serializes via the SAME `getStateSnapshot()` that `GET /api/state` returns (no duplicated serialization) and pushes to all subscribers; failures are logged, never fatal. Action mutations reach other clients within one background tick (~1 s); the acting client still gets its immediate post-action snapshot from the POST response as before. The SSE route (`app/api/events/route.ts`) sends `Content-Type: text/event-stream`, `Cache-Control: no-cache`, `Connection: keep-alive` and `X-Accel-Buffering: no` (prod sits behind Traefik), plus a `: ping` heartbeat comment every 15 s so idle proxies don't drop the connection; snapshot-first-then-subscribe ordering guarantees events are strictly ordered by sim clock, and stream cancel unsubscribes + clears the heartbeat; broadcast pushes are wrapped in `data: <json>\n\n` SSE frames at the route (matching the initial snapshot). Client (`lib/useGameState.ts`): one `EventSource('/api/events')` per page — onmessage parses the full snapshot into the shared state (same shape as today); polling stays as an automatic fallback: if no event arrives within 5 s of connect, or on a stream error, the old poll loop starts (immediate catch-up fetch + interval), and it stops again when fresh events flow. EventSource's native reconnect is relied on — no custom reconnect framework. `/api/state` behavior is unchanged (still ticks-then-snapshots; polling remains fully functional).
 - **API.** OpenAPI spec gains `GET /api/events` (200 → `text/event-stream`) in `lib/openapi.ts`, so the machine-readable spec at `/api/openapi` stays accurate.
