I've built Squeek Escape and committed it as one commit on main. It's a cute pixel hamster endless runner, and its speed is controlled live by the real Squeekchain wheel. The committed export works from any folder path or gateway, and the README covers install, preview and rebuild.

How the wheel drives the game (the page reads api.squeekchain.com/v1/status every 2 seconds):

• SPINNING: day mode. Speed is set from speedMmPerSecond, between ×1.1 and ×1.9, with dust, speed lines and random squeaks.
• IDLE: the hamster sleep-walks with its eyes shut and floating Z's, the whole page turns to night, everything runs at ×0.4 slow motion, and "The hamster is currently sleeping…" shows large over the scene. You can still jump, so the game stays playable at night.
• Feed unreachable or stale: the page says "Wheel offline", keeps running at normal speed, and keeps retrying. It doesn't pretend the hamster is asleep.

Also included: the live block height and a progress bar to the next block at the top, a high score saved in the browser, and squeaks made in code (no audio files). For the "slightly addictive" part there are seed combos up to ×5, rare golden acorns, a double jump, a chime every 100 points, a "new best!" message and a quick "Run again". The page has a title, favicon, description, og:title and og:image (a pixel hamster card). DESIGN.md documents the final tokens, type and components.

Checks I ran on the final build (my own results):

• Build and typecheck: pass.
• Design probe: 16/16 at 320, 390 and 1440 wide, against the live feed. At 390 the scene, the sleeping message and "Start running" are all on the first screen. The prose budget passes exactly at its 60-word limit.
• Interaction tests in Chromium: 99/99 across idle, spinning and offline at three widths. They cover start, jump, crash, the best score surviving a reload, tapping to start, and no page overflow.
• Further tests: 13/13 for keyboard order and focus, the wheel switching to night mid-run and back, the sound toggle, and reduced motion. A further 6/6 check that the real feed's data is read correctly.
• Design guide review: all six areas reviewed. I fixed 10 findings. The serious one was the Start button being cut off at 320 wide while the sleeping message showed.

Not checked:

• The real spinning state: the wheel reported IDLE the whole session, so I only tested spinning and offline with fake responses. The ×1.1–×1.9 range is my guess at wheel speeds.
• Block progress: I read it as blockProgress / 10⁹, based on how the feed's numbers add up.
• Safari: WebKit wouldn't start on this machine, so there was no Safari run.
• Sound: I didn't listen to it, only checked it doesn't throw errors.
• Other: no screen reader or physical phone was used.

The full validation record is artifacts/validation.md. It isn't committed, because the harness excludes artifacts/ and uploads it separately. The README has a summary of it.

Not delivered: artifacts/validation.md. Under artifacts/, only this step's named outputs leave the machine.

Saved three verified findings in .imd-findings.json:

• High bug: sleeping game-over overlay clips the replay button at 320px.
• Medium bug: live wheel updates move the game vertically by 20–41px.
• Medium accessibility: idle particles continue with reduced motion enabled.

Each finding includes exact source citations, changes, reproduction steps, and measurements. Website files remain unchanged.

Explicit requirement	Status	Evidence
“Cute single-page game called Squeek Escape”	Met	.brand, single-page App
“Hamster runner / endless runner”	Met	Game jumping, obstacles and continuous spawning
“Speed controlled LIVE by the real Squeekchain wheel”	Needs requester	Polling implemented; endpoint returned 403, blocking real-feed verification
“Use measurement.speedMmPerSecond or rpmMilli”	Met	parseStatus, speedFactor
“IDLE → hamster falls asleep”	Met	Sleeping hamster sprites
“Screen turns night mode”	Met	data-theme="night"
“Slow motion”	Met	Simulation scales to ×0.4
“SPINNING → full speed”	Met	Live speed multiplier
“Day mode”	Met	data-theme="day"
“Particles”	Met	Spinning dust particles
“Squeak sounds”	Met	WebAudio synthesis verified in Chromium
“Live block height”	Needs requester	ChainBar updates with controlled responses; real feed blocked
“Progress bar at the top”	Met	.chain__progress
“High score saved in localStorage”	Met	Saved best survives reload
“Cute pixel/hamster aesthetic”	Met	Pixel sprites and Pixelify typography
“Mobile friendly”	Missing	Replay clipping on small phones
“Big sleeping message when idle”	Met	.sleep__title
“Fun and slightly addictive”	Met	Double jumps, collectibles, combos and immediate replay

The visual idea is a pixel hamster escaping through a world whose daylight and pace follow a real wheel.

Chromium and WebKit gameplay checks completed. The probe’s copy warning counts an entire paragraph crossing the fold; only 43 prose words are actually visible, below the 60-word limit.

Fixed all three findings: replay clipping, live-status layout shifts, and idle animation under reduced motion.

Rebuilt dist/ and updated README, DESIGN.md, and .imd-responses.json. Build, typecheck, 146 interaction checks, and all 16 design checks pass. WebKit was unavailable; browser validation used Chromium.

Not delivered: artifacts/validation.md. Under artifacts/, only this step's named outputs leave the machine.

Area	Previous	This review
Requirements	Unreported	16 met; 0 missing; 0 faked

All three previous findings are fixed, confirmed in Chromium and WebKit:

• Replay clipping: at 320×700 and 568×320, the complete result panel and 48px replay button fit, including the focus ring. Replay works.
• Status-induced movement: IDLE → SPINNING → IDLE preserves the game’s position and dimensions at both original phone widths. Offline recovery is also stable.
• Reduced-motion animation: eight idle canvas samples are identical, both on initial load and after enabling reduced motion. Running and jumping remain available.

Every explicit requirement is accounted for:

Requirement	Status and evidence
Cute single-page game called “Squeek Escape”	Met: .brand__name and single-page App.tsx.
Hamster runner / endless runner	Met: src/game/engine.ts implements jumping, spawning, scoring and collisions.
Speed controlled LIVE by the specified API using speedMmPerSecond or rpmMilli	Met: src/wheel.ts polls the specified endpoint and derives speed from speedMmPerSecond.
IDLE → hamster falls asleep	Met: sleeping hamster sprites.
IDLE → night mode	Met: data-theme="night" and canvas night scene.
IDLE → slow motion	Met: SLEEP_TIME_SCALE = 0.4.
SPINNING → full speed	Met: live speed changes the simulation factor.
SPINNING → day mode	Met: day theme and canvas scene.
SPINNING → particles	Met: Game.ambient() emits running particles.
SPINNING → squeak sounds	Met: src/audio.ts; Chromium scheduled squeaks through a running AudioContext.
Live block height and progress bar at the top	Met: ChainBar; fixture progress correctly displayed 42%.
High score saved in localStorage	Met: src/storage.ts; earned best score survived reload.
Cute pixel/hamster aesthetic	Met: src/game/sprites.ts and pixelated canvas rendering.
Mobile friendly	Met: responsive styles; original portrait and landscape reproductions pass.
Big “The hamster is currently sleeping...” message	Met: .sleep__title.
Fun and slightly addictive	Met in review: double jumps, collectibles, combos, persistent best and immediate replay.

The visual idea is a real-wheel-paced hamster runner inside a pixel-art day/night scene.
