The work is committed and verified. Here is the recap.

Delivered: Pump Wallet Watch, a static Vite + React + TypeScript site committed with its source, lockfile and production export in dist/ (relative asset URLs, base ./). Commit ed1d8ae, 45 files, submission bundle about 226 KB.

What the site does

• Reads live data in the browser only: trades come from the Solana blockchain through a JSON-RPC node (default public node, owner-settable URL), and coin lists, pump.fun and launchpad labels, market caps and prices come from Jupiter's token and price APIs. pump.fun's own API is behind a Cloudflare challenge and the official mainnet RPC answers 403 from this machine, so neither is used.
• Trades are derived from each wallet's token and SOL balance changes, so the pump.fun bonding curve, PumpSwap, Raydium and aggregator routes all count. Unit tests run the parser on three real mainnet transactions.
• Dashboard: purchase range (default $50 to $500) and market cap range filters, wallets to track, refresh interval, a form to add a wallet, a live status line, the list of tracked wallets still holding, the list of wallets that sold (sale price, profit or loss, holding time), stat tiles (average hold and average profit or loss), a profit-or-loss bar chart and a holding-time histogram, and a data-sources panel. Sold wallets leave the holding list and the freed place is filled by the next qualifying buy.
• Wallet details page and an FAQ page that explains how to read profit or loss and holding time in plain words. Six languages with English as default.

Validation, all run on the final build

• Typecheck passes, 9 of 9 unit tests pass, production build succeeds.
• Design probe taste@1: 16 of 16 checks pass. The first run failed two (columns overlapping at 1440 and a nav pill read as a kicker above the h1); both were fixed and the 390 screenshot confirms the live list and both action panels are on the first screen.
• Browser walkthrough with my own Playwright script: 35 of 37 steps pass across Chromium at 390 and 1440. The live scan found real purchases within seconds. The two misses are environment-bound: the browser logs blocked requests for coin icons whose hosts forbid cross-origin embedding (the site hides those images), and WebKit cannot launch here because host libraries are missing, so Safari rendering is unverified.
• The Better Interface review across its six domains, with findings, fixes and the unperformed checks (screen reader, forced colors, native zoom, widths between 640 and 1024), is recorded in docs/validation.md and artifacts/validation.md. The README documents install, preview and rebuild plus the results table, and DESIGN.md documents the implemented tokens, typography, layout, components and responsive behavior.

Known limitations to be aware of: a fresh visit can show an empty list for a scan or two depending on current on-chain activity and public RPC rate limits, and USD values of SOL trades use the SOL price at scan time.

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

All eight findings check out against the tree, and the only files in the working tree are the findings file and the probe's scratch output. The review is complete.

Requirements, one line each

• "Filter tracked wallets by purchase amount between $50 and $500 (customizable range)": met, the Filters form in src/components/FilterForm.tsx with defaults 50 and 500 and the qualifying check in the tracker.
• "Filter coins by market capitalization (customizable)": met, the market cap fields in the same form and the range check in src/engine/tracker.ts.
• "Display a live list of tracked wallet addresses that have purchased these coins and have not yet sold": met, the "Tracked wallets still holding" card on the dashboard. The probe run found four real wallets within seconds.
• "Automatically remove wallets from the tracking list once they sell, and replace them with new qualifying wallets": met, the sell handling in src/lib/positions.ts moves a position to the sold list and the tracker fills the freed slot on the next scan.
• "purchase price, sale price (if sold), profit or loss in USD, and holding duration": met, the columns of the positions table on both lists.
• "Provide an interface to add wallets manually to the watchlist": met, the "Watch a wallet of your choice" form and the watch button on the wallet page.
• "Show aggregate stats such as average hold time and average profit/loss": met, the seven stat tiles in the right column.
• "clean, modern interface with charts and live data refresh": met, two SVG charts and a 45-second scan with a live status line.
• "reads live blockchain data from Solana network and from pump.fun or launchpad memecoin data sources": met, trades come from a public Solana RPC node and coin lists from Jupiter's launchpad-labelled token lists. The README says plainly why pump.fun's own API is not used.
• "multi-language support with English as default": met, six languages in the header select, English by default.
• "main dashboard page, wallet details page, FAQ page": met, the three hash routes in src/App.tsx.
• "instructions for how to interpret the profit/loss and holding time metrics": met, FAQ answers 1 and 2.
• "Avoid overly technical jargon": mostly met, with one copy finding on "RPC node" and "RPC URL" in visitor-facing text.
• "static frontend using JS to read public blockchain APIs": met, the Vite export in dist/ with no backend.
• Hosting and a live URL: after review.

The idea in one sentence. A quiet white ledger where the only colour is the data: blue for gains, red for losses, a green dot for live. Nothing competes with it.

Findings written to .imd-findings.json, most severe first. None is high, so the build need not reopen, but the four bugs are worth one revision.

• bug, medium: the holding-time chart's six axis labels overlap at 390 and at 1440. Stagger them on two rows.
• bug, medium: the default market cap limit 1000000 is clipped to "100000C" in its input at 1440. Drop the six-column rule in the stylesheet.
• bug, medium: one RPC retry leaks a concurrency slot. After a retry the counter reads -1, so a rate-limited node gets more parallel requests, not fewer.
• bug, medium: when Jupiter's coin lists fail, the notice promises the last known coins stay in use, but the scan reads only already-open positions.
• fidelity, medium: the wallet page's "Received" tile adds the current value of unsold coins, so a wallet with zero sells shows money received.
• copy, medium: errors, the data panel and two FAQ answers say "RPC node" and "RPC URL". Replacement wording is in the finding.
• taste, low: profit chart wallet lab
