The website is built and committed. Two things are not finished: the contract is not deployed to Sepolia, and the browser wallet/mint flow has an open bug. The commit is 349be65, about 600 KB in git, with dist/ included.

Not done

• Sepolia deployment, source verification and a live mint did not happen. No authorized, funded Sepolia signer was available, and I didn't go looking for keys on this machine. No address is configured, so the mint button reads "Mint unavailable: contract not configured". The README has the forge create … --verify command. Once the contract is deployed, put its address in dist/hatchery.config.json and the site picks it up without a rebuild.
• The wallet steps failed in the browser test. The mint button never offered "Connect a wallet to mint" and the connect sheet didn't open. So wrong chain, switching, rejection, pending, receipt success and duplicate handling are unverified in the browser. I suspect initWallet() in src/wallet.ts fails in that environment, but I haven't confirmed it. Duplicate and revert handling are tested at the contract level.

What changed from the prototype

• Egg and lamp: The egg stays still. The lamp is dragged up and down a rail and always points straight into the shell. It works with touch, mouse, keyboard, or the Head / Middle / Lower body buttons.
• Shell: It turns see-through only under the beam, with a soft edge, and the window follows the lamp. At hatching the same hamster is shown in full; nothing is re-rolled.
• Artwork: The hamster is seen from the front, with round ears, fluff and a short pom tail. Head light grows ears, middle light grows fluff, lower light grows the lower coat and pom. Patterns sit on the forehead, chest and belly.
• Real input: Missing, stale, simulated, derived, COUNTER_FAULT or replayed data pauses incubation, and it resumes after a 3-second countdown. Hidden tabs pause with no catch-up. Work counters are exact BigInts.
• Light and pattern: Color depth and pattern visibility both come from local light × time, capped. So a resting hamster's 12% glow still slowly develops the locked pattern; work only picks the pattern.
• Schedule: Every pattern window is 50 work units (stars at 1000–1049, swirls at 2000–2049, and so on), and the old 200-unit windows are gone. Pearl and rainbow passages last 5 m each. The page shows current/next color and pattern, waiting times from the measured pace, and the egg's locked pattern.
• Contract: It stores the SVG, traits and name, and builds the metadata on-chain, so the token matches the download. Mint is free, and each hatch can be minted once in total. The portrait size cap keeps a mint under Sepolia's per-transaction gas limit: about 8.3M gas for a typical mint and 9.8M at the caps.

Checks I ran

• Typecheck and production build: both pass.
• Unit tests: 12/12 pass.
• Contract test on a local anvil chain: passes.
• Browser test (Playwright at 390 wide, against dist/ with the API mocked):
  • Passed: Begin incubation is on the first screen. Keyboard and drag move the lamp. Stale and simulated data pause it, and it resumes after the countdown. A full 60-second hatch completes, the name check rejects a bad name, review shows the portrait, JSON downloads, and save adds to the collection.
  • Not proven: that the SVG download matches the reviewed portrait. The test's comparison method is flawed, so this needs a better check.
• Design probe (taste.mjs): 13/16 pass.
  • Eyebrows fails because it counts the header Connect button as a label above the heading; I left it.
  • Copy budget fails at 1440 wide (128 words on the first screen).
  • Font weights failed (four in use). I cut that to three afterwards but didn't re-run the probe.

Details are in VALIDATION.md (including the Better Interface review), DESIGN.md and README.md. Saved creatures from the old prototype are not imported.

Recorded five findings in .imd-findings.json:

• High — bug: rejected replay data becomes accepted on the next poll and resumes incubation.
• High — bug: valid names and large work counters cause mobile horizontal overflow.
• Medium — bug: renaming during wallet confirmation makes the NFT and downloaded metadata disagree.
• Medium — bug: the share PNG contains a baked-in broken-image placeholder.
• Medium — taste: repeated explanations exceed the desktop copy budget.

Validation covered 12 passing unit tests, Chromium and WebKit hatching flows, native touch input, downloads, collection persistence, and local contract/wallet states. Every finding’s source citation matches exactly. Project files remain unchanged.

The probe’s eyebrow failure flags the conventional header wallet button; I excluded it as a false positive. Its copy-budget failure is confirmed: 128 desktop words against the 90-word bar.

The requirement audit follows. Transaction checks marked met were exercised locally. Public Sepolia deployment, verification and live minting still require an authorized funded signing path. Related brief clauses are counted separately.

Fixed all five findings and rebuilt dist/. Verdicts are in .imd-responses.json; evidence and limitations are in VALIDATION.md.

Build, typecheck, unit tests, Chromium regressions and local mint checks passed. Bundle: under 0.7 MB.

Sepolia deployment/live mint still require an authorized funded signer. WebKit could not launch. No results were fabricated.

All five previous findings are fixed. One additional, reproducible layout defect is recorded in [.imd-findings.json][findings].

High — bug: unavailable previews still force horizontal scroll at 320px. At 320×844 in Chromium and WebKit, abort the status request and scroll to Lamp color and Coat pattern. Their “Unavailable” captions expand the page to 336px; the two preview rows end at 328.19px and 336.19px. Expected page width: 320px.

Change [style.css:113][css] to use minmax(0, 1fr) columns, shrinkable figures/captions and overflow-wrap: anywhere. This preserves complete labels while meeting mobile reflow requirements. Applying that CSS in browser memory restores a 320px page.

Validation passed: 12 rule/art tests, nine Chromium regression cases, the WebKit hatch/name/download regression, and touch, mouse and keyboard lamp interaction in both engines. The remaining taste warning incorrectly classifies the required header Connect button as a kicker.

Squeek Hatchery is a wheel-powered hamster incubator, carried visually by a movable lamp revealing a stationary egg against a plum stage.

The requirement checks follow. “Met” refers to inspected implementation and local validation; public deployment remains outstanding.

1. “website” — met: [app.ts][app].
2. “ERC721 NFT contract on Sepolia (11155111)” — met, implementation: [contract][contract], [wallet.ts][wallet].
3. “NO ERC20 token” — met: contract and wallet source.
4. No “liquidity pool” — met: contract and wallet source.
5. No “mainnet deployment” — met: Sepolia-only wallet configuration.
6. “Minting is optional” — met: optional mint panel in app.ts.
7. “working testnet mint” — needs requester: authorized funded Sepolia signer; [README][readme] documents the gap.
8. “Clone…main…Read source, README.md and VALIDATION.md…improve…do not rebuild” — met for this revision: supplied project retained; source and both documents reviewed.
9. “All UI, metadata and docs must be English” — met: app.ts, [metadata.ts][metadata], README and [VALIDATION.md][validation].
10. “Keep the egg stationary” — met: unchanged egg bounds during both-browser input checks.
11. “Drag the lamp vertically on the right” — met: app.ts pointer handlers.
12. “angle…perpendicular to the egg surface” — met: [rules.ts][rules] geometry and normal-vector test.
13. “touch, mouse and keyboard” — met: exercised in Chromium and WebKit.
14. “60-second…only valid, visible play” — met: rules.ts duration and app.ts frame guards.
15. “transparent locally…soft edge” — met: [art.ts][art] shell mask.
16. Window follows lamp; outside becomes opaque — met: moving shell mask.
17. “Do not expose the whole animal at the start” — met: initial shell rendering.
18. “traits remain stored even when hidden” — met: session regions/bands i

Fixed the preview overflow at 320px: complete labels now wrap without shrinking text or swatches. Rebuilt dist/ and wrote .imd-responses.json.

Build, typecheck, 12 unit tests, 8 browser regressions and 9 preview checks passed. Design probe: 15/16, retaining the existing Connect warning. WebKit was unavailable. Results and limits are recorded in VALIDATION.md.

The unavailable-preview finding is fixed. Both Chromium and WebKit keep scrollWidth=320 and preview right edges at x=288. Complete labels retain 13px text, 44px swatches and 48px miniatures.

All 18 browser/state/width combinations passed. Mouse, touch and keyboard controls worked in both engines; all 12 unit tests passed. The probe’s remaining warning misidentifies the functional Connect button as a kicker label.

Wrote .imd-findings.json containing {"findings":[]}. Application files are unchanged.

This round settles the supplied finding. Sepolia deployment, source verification and a public mint still need an authorized funded signer; none were performed or fabricated.
