Squeek Wheel Runner is built and committed as one commit (ae96ea9) on main. Of the browser checks, only the WebKit/Safari one could not run, because this machine lacks the system libraries WebKit needs. The source is in site/ and runs straight from disk with no build. dist/ is the copy for hosting, about 357 KB committed in total, and node_modules is not in it.

Check results

• Type check and build: both succeed. The build also fails if any local URL is absolute or missing.
• Interaction test (Chromium, served under a subpath): 31 of 31 checks pass. It used the live API plus faked responses for the states the real wheel wasn't in.
  • Live data: values appear within 0.5 s at 320, 390 and 1440 wide, with no console errors and no horizontal scroll. Block and progress match the official site's formula, checked against a separate API call.
  • States: IDLE turns on night/sleep mode, a new block triggers the gold flash and seeds x2, and a failed fetch shows the retry message while keeping the last data.
  • Game: a full run, game over, the share card, PNG download, the X post link, renaming on the leaderboard, keyboard restart and the language switch all work. The /overlay page has a transparent background.
• Design probe (taste.mjs): 16 of 16 checks pass. At 390 wide the Start button sits on the first screen.
• Not done: real phones, a screen reader, and a real block passing 100% live. The wheel was idle the whole session, so the block bonus was only tested with faked responses.

Decisions you might want to change

• Block numbers come from builder.projected, not builder.anchor as the brief says. The acceptance check requires matching sepolia.squeekchain.com, and that site's code shows block projected.blockHeight + 1 with progress projected.blockProgress / 1e9, rounded down to 2 decimals. The two values are normally equal, and the game falls back to anchor if projected is missing.
• The API never returns SPINNING. Its states are ACTIVE, IDLE and COUNTER_FAULT. The hamster counts as running on ACTIVE, SPINNING, or any rpm or speed above zero; that's the same rule the official site uses.
• I added TypeScript as a development-only tool to type-check the plain JavaScript. The site itself still has zero dependencies and needs no build to run.
• The commit author is "charlietkh" with your email. Git had no author configured here, so I passed these for this one commit without changing any git settings.
• There is no .gitignore. I removed the one I'd added because the rules require an explicit path budget for ignore files. Watch for node_modules/ if you use git add -A after npm ci.

Limits to know about

• The X post link can't attach the image, so players attach the downloaded card themselves.
• The overlay's best score is read from the same browser's local storage, and OBS keeps its own storage. The README explains how to play inside OBS so the score shows up.
• The preview image link (og:image) is a relative path until the site has a fixed address.

README.md covers how to play, the data-source table, and how to run, rebuild and deploy. DESIGN.md documents the colors, type, layout and components. VALIDATION.md lists every check, the design-review findings with file:line references and their fixes, and the limitations.

Saved the verified findings, exact source citations, fixes and reproductions in .imd-findings.json. Website files are unchanged.

• High — bug: At 390px, the English wheel-status chip overlaps the SQK column by 25.06px. Give the mobile statistics separate rows.
• High — fidelity: When initial API requests fail, the card, leaderboard and X post invent a measured 0.0 rpm. Preserve and display an unknown reading.
• Medium — bug: An unavailable builder overwrites the last valid block snapshot. This also loses the bonus trigger when a completed block appears on recovery. Retain the previous valid block pair.
• Medium — bug: A retry warning moves the active phone game stage by 91.5px. Place the warning below the game.

The visual idea is a real hamster wheel powering a pixel hamster’s run, carried by the yell

I could reproduce all four findings on the previous export, and each one is now fixed. A Chromium test against the rebuilt dist/, with the API mocked, passes 31/31; the old export fails 15 of the same checks. WebKit and real phones were still not tested: there is no WebKit browser on this machine.

1. Wheel status overlapping the SQK total on phones (high). The overlap reproduced at 320 px. At 390 px this machine's fonts render the status label narrower than on the reviewer's machine, so it only just fit, but the cause is the same. On narrow screens each stat now gets its own row (site/css/app.css). The desktop row is unchanged, and Start run is still on the first screen at 390 px.
2. Missing data shared as 0.0 rpm (high). It reproduced in the result line, card image text, leaderboard and X post. Now, if a run ends before any wheel reading has arrived, the rpm is stored as unknown. The result, card and leaderboard show "n/a" / "暂无", and the X text in both languages says the reading was unavailable (site/js/app.js, site/js/i18n.js). A real reading still appears normally, for example "Wheel 42.3 rpm".
3. Builder outage erasing the last block (medium). It reproduced, including the missing x2 bonus when the data came back. The wheel reading and the block data now update separately, and a bad poll keeps the last good block number and progress (site/js/squeek-data.js). In the test, "Block #4137 building · 1.00%" stayed on screen through the outage, and the toast and x2 bonus fired on recovery.
4. Failure warning moving the game (medium). It reproduced: the game area jumped down 69 px. The warning now sits just below the game controls (site/index.html), and the game stayed in the same position through a failed poll and recovery.

Other checks:

• Build: npm run check (typecheck plus build) passed, and dist/ matches the source.
• Design probe: the review's taste.mjs probe passed 16/16. I looked at its 390 and 1440 screenshots: the data strip stacks on the phone and stays one row on desktop.

README.md, DESIGN.md and VALIDATION.md are updated, and .imd-responses.json answers all four findings as "fixed". I removed the temporary node_modules, and nothing is committed.

All four previous findings are fixed in Chromium and WebKit. No new reproducible defects were found. [.imd-findings.json][report] contains {"findings":[]}. Website files remain unchanged.

Live data populated in 226ms, with zero console errors. Start remains visible at approximately y=464–508 on the 390×844 first screen. Keyboard and pointer jumps work in both browsers.

The visual idea is a yellow pixel hamster runner whose scene and pace follow a real hamster wheel.
