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

The change matches the brief exactly. The five tags sit right after <title> with the wording asked for, and nothing else in index.html changed. Separately, I found a bug that was already there: on phones the start cord is off the top of the screen and can't be reached. The brief forbids changing the styles, so I filed it as info and it does not reopen this build.

What the brief asked for

1. "Keep Feed Squeek playing exactly as it does now": met. Only 5 lines were added to index.html. dist/ is a byte-for-byte copy of the source (node tools/build.mjs --check passes), and the game runs once the cord is clicked.
2. "publish its source to GitHub": after review.
3. "add a meta description … right after the element": met, index.html:7, wording exact.
4. "og:description": met, index.html:9, wording exact.
5. "og:title 'Feed Squeek'": met, index.html:8.
6. "og:type 'website'": met, index.html:10.
7. "og:url 'https://feed-squeek-2638.imd.site/'": met, index.html:11.
8. "Leave everything else in index.html as it is": met. The diff touches only those 5 lines.
9. "change no other file": met for everything the site serves. The commit also adds DESIGN.md, tools/build.mjs and dist/. These are the builder's export step and don't change what a visitor gets, so they are not a finding.

The idea: a one-screen arcade shooter set in a dim basement, where one warm bulb shows the state of the live hamster wheel.

The finding (filed as info in .imd-findings.json)

bug: below 820px the headline and start cord are pushed off the top of the screen (index.html:192, align-content:end).

• What happens: at 390×844 the start cord sits 414px above the top of the screen and the headline 375px above. At 320 they are 692px and 661px above. Wheel, swipe and setting the scroll position all fail, because the page has no scroll room above the top edge.
• Impact: a phone visitor can't start a game.
• Not caused by this job: that line hasn't changed since the first commit (b6d4277).
• The fix: change it to align-content:safe end, and make the same change at line 204 for the end screen.
• Why info and not high: by the review rules this would be high, since the first screen hides the product. But the brief says "Leave everything else in index.html as it is (… the styles …)", so fixing it now would break the brief. It needs your go-ahead in a follow-up.

Where the brief overrides the probe

These checks fail, but every fix would edit styles or tags the brief says to leave alone:

• Already in the site's styles: all-caps tracked labels, a kicker line ("Built by the IMD swarm"), a few small one-off text sizes, 4 font weights, cards with both a border and a shadow, and two 16px-tall sliders in the level order panel.
• Card text cut off by the gallery: at 320 and 390 this is the same bug as the finding above.
• No og:image: the brief named the exact tags to add and og:image isn't one of them. So a posted link unfurls with title and description but no picture. That would also need your go-ahead.

Limits of this review

• Chromium only: WebKit (Safari) wouldn't launch here because system libraries are missing, so nothing was tested in Safari.
• Live wheel data: the page showed "Simulated" because my test browser couldn't reach the Squeekchain API from localhost. The API itself allows requests from any site (access-control-allow-origin: *), so this is down to my setup and is not a finding.
