Saved verified findings to [.imd-findings.json][report]:

• High — bug: valid leaderboard entries overflow the phone layout. With populated contract responses, 1,000,000,000 extends beyond both 320px and 390px screens. Chromium and WebKit reproduce it. Increasing the score column and wrapping nicknames fixes the overflow in a browser preview.
• Medium — bug: dismissing results strands the completed run. Closing the results dialog removes access to that run’s sharing and submission controls. The ended game needs a way to reopen results.

Both browser engines completed customization, play, pause, collision, sharing, and replay. The 10 existing game/data tests passed. Application files remain unchanged.

The visual idea is a hamster wearing wildly inappropriate equipment inside a calm, hand-drawn exercise room.

I reproduced both of the reviewer's findings and fixed them. The diff is small and the rest of the accepted work is unchanged.

1. [high] Leaderboard rows overflowed on phones (25117e56…): fixed.

• Reproduced: I deployed the real contract to a local test chain (Anvil) and added an entry with the maximum score of 1,000,000,000 and the 24-character nickname SirSqueeksalotTheGreates. At 320 wide the page was 328px wide, the score cell needed 114px but had 90px, and the name cell needed 191px but had 148px. These match the reviewer's numbers.
• Fix in src/styles.css: the score column is now 128px wide (was 90px) and nicknames can wrap at any character. The score, nickname and address all stay fully visible; the row just gets taller.
• Regression check: I added a check to tests/chain-ui.mjs that submits that entry and confirms nothing overflows at 320 and 390 wide. It fails on the old CSS (328 vs 320) and passes now. A screenshot at 320 shows 1,000,000,000 fully inside the table.

2. [medium] Closing the results dialog lost the finished run (63639112…): fixed.

• Reproduced: after Close, the ended game only offered Run again, so there was no way back to the score, Share score or the nickname field.
• Fix: the ended game now shows a View results button under Run again (GameBoard.tsx, connected in App.tsx). It reopens the same dialog with the score and the typed nickname intact until the next run.
• Regression check: tests/chain-ui.mjs now closes the results, clicks View results, and confirms the dialog, Share score and the nickname are back. I also checked by hand that there's no sideways scrolling at 320 or 390.

Checks, run after the last change:

• Typecheck and production build succeed; dist/ is rebuilt and still uses relative asset paths.
• Unit tests 10/10, contract tests 11/11, browser tests 17/17 in Chromium.
• Local-chain wallet and leaderboard tests 12/12, including the two new checks.
• The design review's probe passed all 16 checks.
• I did not rerun the WebKit browser tests this time.

Docs and answers: I added these results to the README and updated DESIGN.md for the new column widths and the View results button. The answers to both findings are in .imd-responses.json.

Still open (both existed before this revision and I didn't fix them):

• No Sepolia deployment. The leaderboard contract still isn't on Sepolia, because no funded deployer was provided. The site says honestly that the board isn't live yet, and the README explains how the owner deploys it and adds the address. I didn't stop the job over this, since neither finding depended on it.
• Missing validation file. The README and DESIGN.md link to artifacts/validation.md, but that file isn't in the current files.

To run the local-chain tests I generated the compiled contract file in contracts/artifacts/, which isn't in the repo, and deleted it afterwards. I didn't commit anything.

Both findings from last round are fixed. .imd-findings.json is {"findings":[]} and I changed no repository files. I only re-checked the two findings. The other rows below come from the last round, which this round didn't redo.

[high] Long leaderboard entries pushed the page wider than the phone screen (src/styles.css:788): fixed.

• The change: the score column (th:last-child) is now width: 128px at line 791, and the nickname (td:nth-child(2) strong) has overflow-wrap: anywhere at line 805. The rebuilt dist/ includes both.
• How I checked: I ran the same setup as before, outside the repository: fake replies standing in for a deployed contract, returning one entry with score=1000000000 and nickname=SirSqueeksalotTheGreates.
• Chromium at 320: the page is 320 wide in a 320 screen (last round: 328). The score cell is 128/128 (content width / box width) and the name cell 110/110.
• Chromium at 390: the page is 390/390, the score cell 128/128 and the name cell 180/180.
• On screen: the screenshot shows "1,000,000,000" whole. The nickname and the player address wrap inside their cell and the row grows taller. Nothing is clipped.
• WebKit: not re-run. The installed Playwright couldn't launch it because this machine is missing system libraries. The fix only uses CSS that Safari supports (fixed table layout and overflow-wrap: anywhere), so I don't expect a difference there, but I haven't measured it.

[medium] Closing the results left no way back to the finished run (src/App.tsx:371): fixed.

• The change: the game-over screen now shows a secondary "View results" button (src/components/GameBoard.tsx:235). It calls onViewResult, which src/App.tsx:171 wires to setResultOpen(true).
• How I checked: in Chromium at 320 and at 390 I played a real run until the hamster crashed (24 points at 320, 132 at 390). I typed "Reviewer Hamster" as the nickname, pressed Escape and saw no dialog left. I then clicked "View results". The same dialog came back with "Share score" and the nickname I had typed still in the field. The page stayed 320/320 and 390/390 wide, with no sideways scroll.

Nothing new to report. Re-checking these two flows turned up no other defects I could reproduce.
