Implemented the dashboard with live metrics, 60-second refresh, responsive layouts and searchable settlements.

Build/typecheck passed, plus 15 Chromium validation groups and 16 design checks. Bundle: 0.98 MiB.

WebKit could not launch; limitations are documented. Nothing was fabricated.

I found no high-severity problems. The dashboard meets all 13 requirements in the brief, and nothing is broken. There are 3 medium findings and 1 low one, and they're in .imd-findings.json. No repository files were changed.

Area	Count
Brief requirements	13: 13 met, 0 missing, 0 faked
Broken features	0
Product on the first screen at 390	yes (the four metric cards, Refresh data and Auto-refresh are visible; Live SQK supply is not, see finding 1)
taste@1 checks passed	16 / 16
Copy findings	2 (slogans; the 139 vs 10 count)
Share card	present (title, favicon, og:title, og:image; the probe's share check passed)

Requirements

• "Fetch live data from …/v1/status": met, src/api.ts:2
• "…/v1/economy/state": met, src/api.ts:3
• "…/v1/settlements?range=24h": met, src/api.ts:4
• "Block Height": met, src/App.tsx:67 (5,866)
• "Cumulative Work": met, src/App.tsx:68 (65,847)
• "Distance (km)": met, src/App.tsx:69 (distanceMm ÷ 1,000,000 gives 6.435 km, which is correct)
• "Status": met, src/App.tsx:70
• "Live SQK Supply": met, src/App.tsx:75, read exactly with BigInt (whole-number arithmetic)
• "a table of recent settlements": met, src/components/SettlementTable.tsx
• "clean dark-themed": met, src/styles.css:2
• "modern, responsive": met. There is no horizontal scroll at 320, 390 or 1440 in either Chromium or WebKit.
• "auto-refresh every 60 seconds": met, src/useDashboard.ts:12 and :76-78
• "short README … community project for the Squeekchain Buildooooor badge": met, README.md:3

The idea in one sentence: a calm sidebar dashboard in near-black with one lime accent, where large tabular numbers carry the page. Nothing competes with that look; the only extras are the two slogans in finding 2.

Findings

1. Medium, fidelity: on a phone, Live SQK supply sits below the activity chart, which the brief didn't ask for. At 390 its value is at y=1175, below the 844px fold. Every other requested metric is above the fold. Fix: add .supply-panel { order: -1; } inside the existing @media (max-width: 42rem) block (src/styles.css:378).
2. Medium, taste: a dashboard shouldn't have voice lines, and this one has two. Delete "Real-world work. Recorded onchain." (src/App.tsx:58) and "A little movement. A growing chain." (src/App.tsx:48), and let the rows below each one move up.
3. Medium, fidelity: the "Recent settlements" heading shows a badge of 139, but the list only holds 10 ("1–5 of 10 recent settlements"). Fix: replace the badge with a line computed from the data, "139 settlements in the last 24 hours. The API lists the latest 10." (src/components/SettlementTable.tsx:27).
4. Low, taste: the desktop header has a "Network / Dashboard" breadcrumb that isn't a link and repeats the page heading. Fix: delete it (src/App.tsx:54).

How I checked: I ran the design probe (taste@1) with Playwright installed in /tmp, outside the repository. I also measured the built site at 390 in both Chromium and WebKit, with the live API answering 200 on all three endpoints. I checked the main interactions: search, clearing the search field in WebKit, sorting and paging, the mobile card layout, and the live, loading and failure states in the code. None of them moved unrelated content or broke.
