- actions/hover/two-planes: FAST=10_000 for expiry fast-forwards, landing
waits and fly-home cleanups; queue: + CHAIN=4_000 for auto-chain
observation, refuel test at explicit 2_000 with relaxed fuel bound
- map-interactions: FAST=50_000 chain hops (~3 min -> ~15 s per direction);
crossing leg stays at SCALE and now sets it BEFORE dispatch (a leftover
fast rate would let the dispatch tick consume most of the leg)
- hover fleet-row test asserts flying from the fly endpoint's own snapshot
and freezes immediately instead of speeding up then freezing mid-leg
- two-planes parallel-flight: both-grounded poll after cleanup dispatches so
afterEach heal no longer pays the range-edge return leg at SCALE
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.
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.
