SqueekRace Wheel Relay is fully written, but none of it has ever been run, so this delivery is incomplete. The shell failed on every attempt, including a final try at node scripts/build.mjs. No build, typecheck, test or browser check took place, and nothing is committed to git; the files are only in the working tree. VALIDATION.md records all of this and marks the work Incomplete.

• Shell error: Sandbox is required but failed to initialize: Failed to create bridge sockets after 5 attempts. Restart to retry. Running it outside the sandbox (dangerouslyDisableSandbox) is not allowed either.
• Browser error: Browser "chrome-for-testing" is not installed. Installing it would have needed the shell.

The browser tool's code runner could have started processes outside the sandbox, but I didn't use it, because that would bypass the same restriction. Because this was a tool failure, I didn't write .imd-blocked.json, as the brief says.

Acceptance criteria

Criterion	Status
Usable website with working interactions and responsive layouts	Written, never rendered
dist/ with source and lockfile, relative URLs	In the working tree, not committed; dist/ and the lockfile were written by hand
Build, typecheck and interaction validation with real results	Not met
Browser test results	Not met; none exist, and I made none up
Better Interface review of six domains	Source reading only; every rendered check is marked Not verified, and no contrast ratios are claimed
First screen at 390 wide	Estimated from the CSS only; the required head tags are present
DESIGN.md and README	Done

What's there

• The game: you pick one of three racers and start a 1, 2 or 5 minute run. Each real accepted passage moves the racer one pace around the wheel rim. You pass the baton in gold zones for points, and baton timing can only change the score, never the position.
• States and results: resting and stale are shown as text and icons, each run ends with a recap and a replay button, and practice is labeled throughout and never saved with live results.
• Companion link: the Grand Prix is linked from the header and the page body.

Decisions to review

• Live source: the game reads /v1/status, not /v1/measurement/runs. runs lists oldest-first from October, so reaching live data would mean walking the whole history. The rise in cumulativeWorkUnits between readings gives the same passage count.
• No Vite or React: the site is plain ES modules typed with JSDoc, because that was the only way to deliver a real dist/ without a bundler. npm run build simply copies src/ to dist/.
• Replay: the button starts a new run with the same racer, length and mode; it doesn't play back the previous run.

Check these first

1. Run the checks: npm ci && npm run build && npm run typecheck && npm test, then the browser walk in tests/browser.mjs. The tests are unrun too, so a failure could be in the test.
2. Watch one live run during a busy period, usually around 21:00–23:30 UTC. The wheel was resting during all my fetches, so I never saw the counter rise. If it only updates when a round closes, racers would jump every ten minutes, not move smoothly.
3. Replace the share image: og.svg is an SVG, and many link previews need PNG or JPEG. I couldn't write a binary file here.

One slip of mine: I sent a stray write to a path outside the workspace. It was denied and created nothing.

Saved five findings in .imd-findings.json: 1 high, 4 medium.

• High, fidelity: required browser-test results are absent from the builder’s handoff.
• Medium, bug: an outage produces “The wheel rested all run.”
• Medium, bug: passages observed after zero still increase the timed score.
• Medium, bug: repeated cached responses keep an old feed marked fresh.
• Medium, taste: desktop prose exceeds the probe’s budget.

The visual idea is clear: a real hamster wheel becomes a circular baton track.

Review checks passed: 35 unit tests and 14 scripted browser checks. Direct live-browser requests returned ERR_EMPTY_RESPONSE, so production movement remains unverified. Application files were unchanged; no data or results were fabricated.

I fixed four of the five findings in the source, but none of the fixes has been run. The fifth finding, the missing browser test results, is still open because no browser or command could run on this machine.

What failed:

• Command tool: every command, even pwd and node --version, stopped before it started with Sandbox is required but failed to initialize: Failed to create bridge sockets after 5 attempts. Running outside the sandbox is disabled. So the build, typecheck, unit tests, tests/browser.mjs and the design probe could not run.
• Browser tool: its Chromium crashed on launch with Socket path too long: .../.cache/tmp/org.chromium.Chromium.*/SingletonSocket, then SIGABRT. Its temp folder is under this job's long working path. WebKit can only be reached through the command tool.

Answers to the findings (all in .imd-responses.json):

• Missing browser results (high): disputed, not faked. The reviewer is right that they're missing. VALIDATION.md and the README now record both rounds' attempts with the exact errors, and say plainly that there are no Chromium or WebKit results and no screenshots. Producing them needs a machine where the shell or Chromium can start, for example one with a shorter temp path. There, node tests/browser.mjs --out <dir> writes the results and screenshots.
• Stale feed shown as fresh: fixed (src/js/feed.js:114 and :137). A reading's age now starts when that measurement first arrives, minus the age the API reports. Fetching the same cached reading again no longer resets it, so after 45 s the feed shows stale and live start is disabled. I added three unit tests for this, also not run.
• Passages after the deadline: fixed (src/js/main.js:392). A reading counts only if the device observed it before the clock reached zero. A later reading adds nothing and ends the finish wait, and the recap says how many passages were left out. The trade-off is that passages just before zero are lost when they arrive in a reading observed after it.
• "The wheel rested all run": fixed (src/js/main.js:607). That title now needs no stale time, no counter restart and an arrived finish reading. Otherwise a run with no passages is titled "No passages observed" and says the feed was incomplete.
• Desktop word count: fixed (src/index.html:153). The source paragraph is now the reviewer's 17-word version, with the API link kept. That brings the count from 115 to about 86 words against a limit of 90. I counted by hand; the probe hasn't confirmed it.

Since the build couldn't run, I applied each edit to the matching file in dist/ by hand. Their line counts still match src/, though no byte-for-byte comparison was possible. The README describes the new timing and stale rules. Nothing was committed.

Saved two findings in .imd-findings.json:

• High — fidelity: browser results remain absent from the builder’s handoff. The documented launch failures explain the gap; the requested artifact is still missing.
• Medium — taste: desktop prose remains above budget. Replacing the empty-history message with “Finish your first live run.” measured 84 words in a browser-only check.

All three prior bugs are fixed, confirmed in Chromium and WebKit. Both engines passed the seven-check browser walk; all 38 unit tests passed.

The visual idea is a hamster wheel turned into a relay track, with racers and gold baton zones carrying the interaction.

Direct browser API requests returned ERR_EMPTY_RESPONSE; curl reached the endpoint. Movement checks used explicit fixtures. Nothing was fabricated, and website files were unchanged.

Fixed both findings and rebuilt dist/.

• Chromium and WebKit: 7/7 checks each, with reports and screenshots included.
• Build, typecheck and 38 unit tests passed.
• Design probe: 16/16; desktop prose reduced from 97 to 84 words.

VALIDATION.md records the results and limitations. Browser tests use scripted API responses; real live-service behavior remains unverified.

Both prior findings are fixed. Browser results and screenshots now accompany the source. The revised empty state preserves the storage disclosure; raw probe measurements confirm 34 mobile / 84 desktop prose words.

The visual idea holds: the hamster wheel is the relay track, with gold baton zones explaining the timing.

I reran all 38 unit tests, verified source/export hashes and decoded all 14 delivered PNGs. Fresh browser/probe execution was blocked by a browser-launch failure; browser conclusions use the included reports and screenshots. Real active-wheel browser operation remains unverified. Nothing was fabricated.

.imd-findings.json contains {"findings":[]}. Application files are unchanged.
