Implemented Hamster Hub with Nut Dash, a dashboard, searchable project directory, saved links, and responsive pixel art.

Passed: build, typecheck, 8 game tests, 46 Chromium checks, and 16 design checks. WebKit remains unverified because required system libraries are missing.

The complete dist/ export is ready for IdentityMD’s IPFS publishing pipeline. Documentation includes README.md, DESIGN.md, and artifacts/validation.md.

Not delivered: artifacts/browser-validation.json, artifacts/build-manifest.json, artifacts/contrast.json, artifacts/screenshots/arcade-1440.png, artifacts/screenshots/arcade-390.png, artifacts/screenshots/dashboard-1440.png, artifacts/screenshots/dashboard-390.png, artifacts/screenshots/directory-390.png and 9 more. Under artifacts/, only this step's named outputs leave the machine.

I couldn't run the taste probe or open the site in a browser: the shell sandbox failed to start, and the headless browser isn't installed. Everything below is judged from the source and CSS, not from measurements or screenshots. Six findings are in .imd-findings.json; one is high. I changed no files apart from writing that findings file.

Requirements

• "pixel-art hamster themed homepage": met. The hamster, valley and acorn art is in public/art/*.svg, shown by HeroArt (src/App.tsx:22), with Pixelify Sans headings.
• "introduction to the Hamster ecosystem and IMD": met but thin. IMD is explained plainly (App.tsx:710-723). Hamster is never said to be anything (App.tsx:695): medium finding.
• "useful dashboard showing ecosystem information": missing. #/dashboard only counts the site's own 8 links and this browser's scores (App.tsx:476): high finding.
• "interactive hamster mini-game": met. Nut Dash (src/components/Game.tsx, src/game/engine.ts) has 3 lanes, a 30-second round, 3 hearts, pause and replay, and keyboard and touch controls.
• "project directory with useful ecosystem links": met. 8 sourced links with search, category filters, a saved-only filter and an empty state (App.tsx:265, src/data.ts).
• "responsive design": met by reading the CSS (breakpoints at 1120, 820, 600 and 360 px in src/styles.css), but not measured.
• "Retro pixel-art aesthetic": met (pixel SVGs, image-rendering: pixelated, Pixelify Sans).
• "Orange, brown, cream and dark colors": met (the tokens in styles.css:15-42).
• "Clean typography and smooth interactions": met. 6 sizes, 3 weights, 2 families; transitions name their properties and stop under reduced motion.
• "Professional and visually polished UI": met but thin. The headings read as slogans: medium finding.
• "fully functional / all buttons work": met as far as the code shows; nothing was clicked.
• "No fake live blockchain data": met. The dashboard and About state it plainly (App.tsx:406, App.tsx:736-742).
• "No new token or smart contract": met.
• "Host on IPFS": after review. base: "./" and hash routes make it ready to pin.
• "Include a README": met (README.md), but some of its evidence links are dead: low finding.

The idea: Hamster Hub is a cozy hub for Hamster Hour and IMD, carried by one pixel hamster in an autumn valley. Keep the hamster; cut the extra taglines and the decorative ✳ that compete with it.

Findings

1. High – fidelity: the dashboard has no information about the ecosystem. Replace the bar chart of the site's own link counts with sourced Hamster Hour facts: the token and hook addresses and the IMD launch job, each with its source link and date (src/App.tsx:476).
2. Medium – taste: the hero has four slogans, and "Small paws. Big possibilities." could belong to any site. Suggested headline "Catch acorns. Find Hamster." with a plain sentence under it; delete the footnote and the label over the art (App.tsx:146).
3. Medium – taste: on these tool pages the headings are taglines ("Follow the hamster trail.", "Your little corner.") instead of naming the page. Each finding gives the replacement headings (App.tsx:290 and the other cited lines).
4. Medium – fidelity: "What is Hamster?" never says what Hamster Hour is, although data.ts:98 already mentions the HAMSTER token and

Recorded one high and one low finding in .imd-findings.json.

• High — bug: the production export omits the dashboard’s final wrapping styles. It measures 522px wide at 320px and 526px at 390px. Applying the existing source stylesheet removes the overflow. Regenerate dist/ from the final source; this also ships the revised Arcade heading.
• Low — bug: README links still reference an absent artifacts/ directory. Remove those claims or deliver the referenced files.

The earlier dashboard-content, hero, introduction and decorative-glyph findings are fixed. The heading finding is partially fixed: visitors still see “A dash of hamster.” in the exported Arcade page. The README finding remains reproducible.

The dashboard facts agree with the linked Hamster Hour repository and IMD launch record.

Core interactions passed in Chromium. WebKit was unavailable. No application files were changed.

Hamster Hub is an ecosystem guide and pocket arcade carried by one visual idea: a pixel-art hamster in an autumn valley.

I fixed both findings, but only by hand-editing dist/: the rebuild the high-severity finding asked for never ran. The phone-overflow fix is untested. Nothing was built, typechecked, tested or opened in a browser this round.

What blocked the rebuild

• Shell: all six Bash attempts failed with Sandbox is required but failed to initialize: Failed to create bridge sockets after 5 attempts, and running outside the sandbox is disabled.
• Browser: the browser tool has no Chrome installed, and installing it needs the shell.
• Workaround I didn't use: browser_run_code_unsafe could probably have launched npm, but that would have sidestepped the sandbox block, so I left it alone.
• Not run: npm run build, typecheck, the tests, check:export, validate:browser and taste.mjs.
• Not committed: with no shell, the changes are only in the working tree.

Findings

High – stale export (marked fixed, unverified). The finding holds from reading the files: the source had the .fact-* styles and the Nut Dash heading, and dist/ had neither. I didn't reproduce the overflow itself.

• CSS: added the missing .fact-* rules, including overflow-wrap: anywhere and the 820px stacking rule, and removed rules for classes the source no longer uses.
• JS: changed the Arcade title to Nut Dash. It was the only difference I found reading the bundle's app code against src/.
• Checked by search only: the new rules are in dist/, and the removed rules and old heading are gone.

Low – missing artifacts/ references (marked fixed). The references are gone from README.md, and a search confirms none remain. DESIGN.md had the same problem, so I fixed it there too. I also corrected its outdated mentions of category bars and the scene label, and the README's dashboard description.

Things to know

• Filenames: both patched dist/ files keep their old hashed names, because I couldn't rename or delete anything. The hand-written CSS may also differ slightly from real Vite output.
• Older results: the earlier pass results stay in the README, now labelled as not covering the current export.
• Six-domain review: the detailed report isn't in the repository. The README's new review section covers only the dashboard facts and Arcade heading, by reading the code, so the "records coverage" criterion is only partly met.
• Likely cause: the bundle has a variable the minifier wouldn't produce (.map($f=>), so an earlier round probably hand-edited the JS and skipped the rebuild. That's an inference, and this round repeats the same kind of hand edit.
• Left open: .fact-link:hover isn't limited to devices with hover, so the color can stick after a tap on phones. It's low severity and noted in the README and DESIGN.md.

Next step

Once the shell works, run this from the repository root to replace the hand edits with a real build:

npm ci && npm run typecheck && npm run build && npm test && npm run check:export && npm run validate:browser

Then run the taste.mjs probe and re-run the reviewer's 320px and 390px check on the dashboard. The answers to both findings are in .imd-responses.json, and they state these limits too.

Share card	Not supplied	Present; 1200×630

Both earlier findings are fixed:

• Dashboard export: serving the delivered dist/ without rebuilding gives widths of exactly 320px, 390px and 1440px. Both complete addresses wrap with overflow-wrap: anywhere, source links remain separated, and Arcade displays Nut Dash.
• README references: README and DESIGN no longer claim the absent validation artifacts.

Twelve Chromium interaction checks passed, covering navigation, directory filters and search, saving, persistence, dashboard controls, disclosures, game controls, pause/resume, completion, replay and storage failure recovery. No script errors or failed local assets were observed. Safari remains unverified because WebKit was unavailable.
