SQUEEK RUNNER: AURA PROTOCOL is built and every requested feature is in, but it hasn't been tested in Safari or on a real device. The static export is in dist/ with relative asset URLs, and everything added comes to about 908 KB of the 8 MiB limit.

Nothing is committed yet. Your rules put .git/ off limits, so all the work is uncommitted in the working tree, ready for the submission step to pick up. dist/, the source and the lockfile aren't ignored by Git. node_modules and the caches are.

What was built

• Game: Vite, React and TypeScript around a Canvas game, with mouse, touch and WASD/arrow-key controls.
• Brief items: all the collectibles, obstacles, live rank tiers, particles, screen shake, synthesized audio with mute, and the start and Game Over screens.
• Scoring and difficulty: speed and spawn rates rise with Aura.

Check results

These ran on the final build; rebuilding afterwards gave byte-identical files.

Check	Result
Production build and typecheck	Passed
Unit tests and balance simulation	34 of 34 passed
Browser interaction checks (Chromium)	99 of 99 passed
Design probe (taste.mjs)	16 of 16 passed
First screen at 390 wide	Confirmed: game, HUD and PLAY LIVE all visible
WebKit	Did not run

The Better Interface review covered all six domains and logged 14 findings, all fixed. The worst was the engine never receiving the HUD's height, which let the mouse go under the HUD. The balance simulation also showed that a laser grid's final reach disappeared the moment it went live, so that footprint now stays marked.

Not verified

• Safari/iPhone: WebKit won't launch here because system libraries are missing, so I only audited the source for unsupported features.
• Real devices: touch was emulated, and no phone was used.
• Frame rate: headless software rendering gave 53.5–61 fps at top difficulty, and one earlier run of normal play dropped to 37 fps with no known cause. So 60FPS isn't proven on real hardware.
• Audio: I confirmed the sounds fire and that mute silences them, but nobody has listened to them.
• Difficulty: tuned against a simulated player, not people. Desktop is still the hardest size (median run 26s, against 38s on a phone).
• Screen reader and links: no screen reader session was run, and the X and squeekchain.com links were checked by their URLs, not opened.

Choices to review

• Additions you didn't ask for:
  • One hit ends a run.
  • Multiplier steps decay after 14 seconds.
  • There's a pause feature, and a run auto-pauses when the window loses focus.
• Test hook: a #qa URL hash exposes the running game for tests and can change the score. It's off in normal play and documented in the README.
• "Genesis WL": this is only an in-game title. The README says it grants nothing on Squeekchain.
• Mouse vs hamster: squeekchain.com's title says "Hamster-powered blockchain", and only that title could be fetched. I kept your Cyber-Mouse and followed the brief's theme.

Environment notes

• The permission layer refused one export-style command, so I set the browser path inline for each command instead.
• artifacts/ is excluded from Git, so the full review record is also at docs/validation.md, which is what the README and DESIGN.md link to.

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

Saved the review in .imd-findings.json. Site files are unchanged.

bug: final-rank hint overlaps Pause. At 720×700, reaching 2,500 Aura places “Top rank” underneath the Pause button, covering 44px of the hint. Omit that redundant hint at the final tier. The report includes the exact source citation and deterministic reproduction.

All requested features are present; the HUD has the layout defect above.

The visual idea is a neon Cyber-Mouse surviving traffic across a dark mempool grid.

All 99 Chromium interaction checks passed. WebKit failed to launch because runtime libraries were missing; Safari, physical-device performance and subjective audio quality remain unverified. No results were fabricated.
