WHEELY Stage is built and committed as d30339f on branch wheely-stage, with the source, lockfile and static export in dist/. It adds about 0.8 MB against the 8 MiB limit. The public GitHub repo and hosted site aren't done: this assignment says publishing happens after the job, from the committed dist/.

What it does

• /overlay/: a transparent OBS source that scales between 720p and 1080p, with hud, stage and ticker URL toggles.
  • Idle: a hamster in a nightcap sleeps and breathes slowly, with dim sparks.
  • Active: speed lines and sparks scale with RPM, and the wheel spin follows the real speed.
  • Round settled: a short flash, confetti and one rotating caption.
  • Stale or offline: a chip appears, the numbers freeze, the curtains partly close and nothing moves. If no data has ever arrived, the curtains stay shut and the fields show --.
• / (the desk): the same live fields in large type, the Ghost Race mini-game and an OBS panel that builds and copies the overlay URL.
• Ghost Race: you tap to race your ghost against the wheel's reported distance over 30 m. The best score stays in that browser only, and a heat run while the signal is down counts as practice and isn't saved.

Check results

Check	Result
Production build and typecheck	Passed
Unit tests	42 of 42 passed
Browser tests in Chromium, including one read of the real API	29 of 29 passed
Design-critic probe, online and offline	16 of 16 passed, both
Better Interface review of all six domains	13 findings fixed, none left open

The tests also caught two real bugs, both fixed: steady tapping could never finish a race, and notices could push the Run button out from under a viewer's finger.

What wasn't verified

• Active wheel: the real wheel stayed idle in every sample I took, so the active state, the celebration and the moving wheel lane were only tested against a mocked API. The settled round did advance from 367 to 371 in the real feed during the work.
• Race balance: idle readings changed only about once a minute. If the wheel reports that slowly while running too, its lane may barely move during a 20–30 second heat. I kept it showing reported distance only rather than inventing motion, so check this first once the wheel is running.
• Safari and OBS: WebKit couldn't launch here because system libraries are missing, so Safari is untested. OBS itself wasn't run either; transparency was checked with a no-background screenshot in headless Chromium.
• Accessibility: no screen-reader session, physical device test or native browser zoom was done.

Choices to review

• / instead of /desk: the brief allowed either, so /desk has no page of its own.
• Ticker: it swaps one line at a time rather than scrolling, so it stays readable and stops completely when frozen.
• Commit author: this machine has no git identity, so I passed Claude <[email protected]> for this one commit. I kept your email out of it because the repo is meant to go public.
• Branch: the work is on wheely-stage rather than main, so whatever publishes dist/ needs to read that branch.
• .gitignore: I created one to keep node_modules out of Git, which your rules say needs a path budget. I wasn't given one, so please confirm it's acceptable.

Start with README.md for the OBS steps and rebuild commands. DESIGN.md covers the design system, and VALIDATION.md has the full review record.

Fixed all four findings and rebuilt dist/. Recorded responses in .imd-responses.json and updated documentation.

Build, typecheck, 47 unit tests and 14 component checks passed. Deliverable: 1.03 MiB.

Browser/E2E and design-probe verification remain incomplete: Chromium failed during startup with socket-path errors and SIGTRAP. Details are in VALIDATION.md.
