Implemented Squeek Runner with complete gameplay, local scores, wallet connections, and Sepolia detection. The production export is ready for network IPFS publishing.

Build, typecheck, 13 tests, 14 Chromium checks, and 16 design checks pass. Complete delivery: approximately 1.40 MiB.

Setup and documentation · Validation report

The on-chain leaderboard is explicitly marked as future work. Real wallet approvals remain unverified; WebKit could not run because required system libraries were missing.

Recorded in .imd-findings.json:

• High — bug: Connecting a wallet at 320px produces a 344px-wide page and clips the wallet control.
• Medium — bug: Clicking HUD controls disables advertised keyboard shortcuts through retained button focus.
• Medium — bug: Opening a player address blocks game input while the run continues and ends behind the dialog.

Each finding includes exact source snippets, reproduction steps, measurements, and a concrete fix.

The visual idea is a scarf-wearing mouse chasing cheese across a quiet, sunlit pantry shelf.

Chromium coverage completed. Wallet checks used simulated providers; real approvals and mobile app handoffs remain unverified. WebKit could not launch, so Safari coverage remains unverified. Site source and export were unchanged.

Fixed all three reproduced issues and rebuilt dist/.

Build, typecheck, 13 unit tests, 18 Chromium interaction checks, and 16 design checks passed. WebKit remains unverified because required libraries are unavailable.

Responses are in .imd-responses.json; results and limitations are in artifacts/validation.md.

All three earlier findings are fixed:

• Connected wallet overflow: at 320px, the button ends at x=289px and horizontal scroll remains zero. Full-address disclosure still works.
• HUD keyboard shortcuts: pointer activation returns focus to the canvas. P/Escape resume, Up/Space jump, and native keyboard button activation remains functional.
• Player-address dialog: opening it pauses the run; the score stayed unchanged for 1.5 seconds. Closing restores focus and requires explicit resume.

The visual idea is a small gray mouse chasing yellow cheese across a warm pantry shelf.

WebKit could not launch, so Safari remains unverified. Wallet checks used simulated providers, without real approvals.
