The Squeek Predict site is rebuilt as a dark, sportsbook-style prediction market. It still uses the existing SqueekPredict contract on Sepolia and reads live data from SqueekCore. The final checks passed. Nothing is committed yet: this machine has no git author identity, so all 37 changed files are staged but not committed.

One limitation to know first: the contract can only settle one kind of bet, "more than X Squeek blocks over a 24-hour or 7-day window". Nothing could be deployed in this job, so markets on 1h/3h/6h/12h windows, longest runs and morning-vs-night comparisons are shown as stats in a "Wheel form" panel, not as bets. Making those bettable needs a new contract version. The README and the panel itself both say this.

What the site now does:

• Market cards with odds: each market shows as an over/under line. "More than 1,000 blocks?" appears as Over 1,000.5 / Under 1,000.5, so exactly 1,000 counts as Under, matching the contract. Odds are based on the pools, e.g. 1.67x, and a side nobody has bet on yet reads "Open".
• Wheel form panel: real certified data, including blocks per 10-minute round over the last 24 hours, totals for 1h to 7 days, longest run, best 24 hours this week, and night/morning/afternoon/evening activity. A status card says whether the wheel was running and how far behind the data is. SqueekCore's certified data currently runs about 8 days behind real time, so the site states that, and results can take days to arrive.
• Filters and sorting: by status (Open / In play / Settled), length, market type and search; sorted by closing soon, biggest pool or newest.
• Bet slip: opens from an odds button, as a bottom sheet on phones.
• Creating markets: six suggested markets with lines taken from the last 7 days ("will it run at all", "beat this week's record", "night shift from 18:00", a weekly line, a custom one). You can pick any start time from 65 minutes to 7 days ahead.
• My bets: a one-tap Claim for each payout, plus loading skeletons and empty and error states.
• There are currently no markets on-chain, so the live site opens on an empty board with the suggested markets. I didn't add any fake markets.

Checks (after the last code change):

• The production build and typecheck passed. The build warns that the main script file is large (656 kB) because of the wallet libraries.
• 8/8 unit tests passed.
• 10/10 browser interaction tests passed in Chromium with a simulated wallet and blockchain. They covered filters, betting, creating, claiming, resolving and an outage with retry. They also confirmed at 390 and 320 wide that the main action is on the first screen with no sideways scrolling, and an automated accessibility scan found no problems.
• The design review script passed 16/16 against live Sepolia data. Fixes it prompted are listed in artifacts/validation.md.
• Not tested: Safari, real phones, screen readers, native browser zoom, and real wallet signatures. No transaction was sent.

DESIGN.md documents the final colors, type, components and responsive behavior. The README covers install, preview, rebuild and how to use the site. I removed two outdated check files from the previous job and replaced the screenshots.

Files are in the repository root:

• DESIGN.md
• README.md
• artifacts/validation.md
• dist/index.html

Saved the reproducible findings in .imd-findings.json.

The high findings cover mobile overflow from valid long betting lines and the wallet’s wrong-network state. The medium findings cover failed history reads displayed as zeros and “Runs/Rests” wording that misrepresents a block-completion wager.

The visual idea is a dark Squeekchain sportsbook built around paired mint/coral odds buttons.

Validation passed: 8 model tests, 10 Chromium scenarios, typechecking, ABI verification, and WebKit interactions before signing. No real wallet transaction was sent. Application files remain unchanged.

Reproduced and fixed all four findings. Rebuilt dist/, updated documentation, and wrote .imd-responses.json.

Build, typecheck, 9 model tests, 15 Chromium scenarios, and 16 design checks passed. Submission changes remain under 8 MiB.

WebKit validation could not run because required system libraries are missing.

All four prior findings are fixed. .imd-findings.json contains {"findings":[]}.

• Long market lines: uint64 maximum thresholds fit at 320/390/1440px. Phone document widths are 320/390px; slip client and scroll widths both equal 318/388px. Complete labels remain readable.
• Wallet header: disconnected, connected and wrong-network states fit all 16 tested widths, including the reported phone/tablet failures. Network switching works through the mock provider.
• Incomplete history: missing and uncertified endpoints produce unavailable/retry states. Recovery restores exactly 18/54/108/216/432/3,024 blocks.
• Wager wording: zero-threshold markets use “At least one block / No blocks.” Positive partial-block work produces no resting claim; streak labels explicitly describe completed blocks.

The 15 Chromium scenarios passed across bounded runs. Live reads from all three supplied RPCs matched the pinned Sepolia deployment, runtime and ABI. The live board had zero markets and disclosed that certification was eight days behind. At 390px, Create market occupies y=235–279px.
