The world always runs at WORLD_TIME_SCALE = 24 (lib/worldClock.ts). A server
background tick (instrumentation.ts -> startBackgroundTick, 1 s interval)
advances the sim with no open browser; idle-pause freezes the clock exactly
while no plane is flying or in repair. Fresh worlds start year 2000
(STARTING_CLOCK_MS in seed.ts).
- Removed: POST /api/sim + OpenAPI entry, applyTimeControls/clampTimeScale,
lib/timeScale.ts, LeftPane pause button + scale slider machinery,
ISS-057 slow-on-landing/resume in flyPlane.
- Snapshot simState is now { clockMs } only; client extrapolates at the fixed
rate between polls and freezes while idle (useSimClock).
- New test-only hook POST /api/test/set-timescale behind FLIGHT_TEST_HOOKS=1
(sibling of set-health); all e2e setScale helpers call it, afterEach restores
the world rate. E2E pause tests replaced by idle-pause assertions; sim.spec.ts
activates the world via set-health + /repair for advance/expiry tests.
- flyPlane 409s a broken plane (health <= 0) before any refuel math — fuel/cash untouched
- engine auto-chain skips chaining when a landing's wear breaks the plane (queue kept intact)
- finishRepairs heals along round(f x 100) each tick; flip to available at exactly 100 on gate pass
- repairPlane no longer jumps health to 100 — it starts the gradual heal
- REMOVED BROKEN_BURN_MULTIPLIER / conditionBurnMultiplier and all burn sites (unreachable now)
- OpenAPI + route comments reworded; unit tests reworked; e2e maintenance.spec.ts per issue
- v0.45.0
New terminal status 'ignored' + ignorePackage action + POST /api/packages/{packageId}/ignore
(no body, no penalty; top-up logic refills the market). Ignore button per open-package row in
the Jobs tab. OpenAPI gains the 13th endpoint; unit tests for the action (happy/409x5/404),
engine terminal-status coverage, and a new e2e spec test.
- planes.queue TEXT NOT NULL DEFAULT '[]' — ordered JSON array of not-yet-started
leg ICACs; active leg stays destIcao + departureSimTime. DDL + guarded ALTER
migration for existing DBs; seed sets queue: [] explicitly.
- deliverPackages() auto-chains on arrival: with a non-empty queue and fuel
covering the first queued leg (same requiredFuelFor rule as /fly), the plane
immediately starts that leg from the arrival airport (stays 'flying',
departureSimTime = arrival instant, queue shortened). Short tank → grounds
safely with the queue kept intact; empty queue → unchanged grounding. Cargo
delivery for the reached airport runs first and is unaffected. Ordering kept:
delivery still runs before tickOnce's pause check, so a chained plane counts
as still flying — no premature last-plane pause (ISS-041 preserved).
- New endpoints via performAction(): POST /api/planes/{planeId}/queue {destIcao}
(append; works grounded or flying; 400 bad body/unknown ICAO, 404 unknown
plane) and POST /api/planes/{planeId}/queue/cancel {index} (remove queued leg
by index; active in-flight leg never affected; 400 non-integer/out-of-range,
404 unknown plane). Both return the full state snapshot.
- PlaneState.queue: string[] in /api/state (null/malformed-safe parse helper
shared with the engine); OpenAPI updated (PlaneState.queue, QueueLegRequest,
CancelQueuedLegRequest, both paths) and openapi.test.ts expectations extended.
- Tests: auto-chain block in engine.test.ts (chain / short-fuel ground / empty
queue) + chained-plane-no-pause regression guard; queueLeg/cancelQueuedLeg
blocks in actions.test.ts; type-compat queue: [] fixtures in deriveEvents,
right-pane, mapData and seed tests.
v0.25.0 — part 1 (backend) of ISS-043; UI/map rendering lands in a follow-up.
Replace the ISS-011 auto-slow with pause-on-landing: when the last plane
in flight lands, tickOnce sets sim_state.paused=true WITHOUT touching
timeScale (speed preserved). flyPlane() now clears paused before
persisting so starting a flight resumes a paused sim — inside runAction(),
tick + unpause + dispatch are atomic under the sim lock.
Tests: engine.test.ts auto-slow block rewritten for pause semantics; new
flyPlane test asserts dispatch clears paused with speed untouched. E2E:
auto-slow.spec.ts renamed to pause-on-landing.spec.ts asserting the new
behavior (paused=true AND timeScale still 1000 after landing; /fly clears
paused). Cross-cutting fix: every per-spec setScale helper now POSTs
{timeScale, paused:false} — a scale-only fast-forward after a landing would
otherwise leave the clock frozen. Deliberate mid-test pauses untouched.
Part A: r(F) = k(We + rho*F) L/km, k calibrated so a full tank burns exactly
the old constant; closed forms in lib/sim/movement.ts (fuelAtWeighted,
requiredFuelFor, burnRateConstant, FUEL_DENSITY_KG_PER_L). Catalog gains
emptyWeightKg (ATR72 OEW 9300 kg), exposed in the snapshot. All three burn
call sites (engine landing, state live fuel, fly validation) moved to the
weighted model; old constant-rate fuelAt removed.
Part B: POST /api/planes/{planeId}/refuel takes an optional body
{mode:'full'|'forFlight', packageId} — no body keeps today's fill-to-full
behavior exactly (fuel lands bit-exact on maxFuel); forFlight adds just
enough for the loaded package's destination leg (409 not-loaded/expired/
doesn't-fit, 400 bad body). UI: per-cargo-row 'Refuel' button
(refuel-for-{pkg.id}), market button renamed 'Refuel to full'.
OpenAPI: RefuelRequest schema + optional requestBody + 400 on refuel, fly's
409 description updated, CatalogEntry.emptyWeightKg. Tests: new weighted-burn
suite, forFlight action/route cases (incl. ~7670 km UNNT<->LPPD doesn't-fit),
openapi guards; landing-fuel assertions in engine.test.ts + e2e/actions.spec.ts
use the closed form; the e2e 'return leg unfuelable' scenario reworked — a full
tank now covers the EDDF<->LEZL round trip, so the 409 moves to the second
outbound. New e2e: row Refuel deducts exactly L*price / raises fuel by exactly
L via the endpoint's own response snapshot.
