Updated the footer to Built by @XiaoLingEr888, matching latest main (82a7093), and rebuilt dist/ for redeployment. No other website changes.

Build, typecheck, 27 Chromium checks and 16 design checks passed. WebKit and live API access remain unverified; details are in TESTING.md.

Under artifacts/, only this step's named outputs leave the machine.

The footer change is done correctly, but the page still names a second builder. The title card at 390 and the link-preview image both still say "Built by 0xRicher", so one page credits two different people. That's the only finding, and it's medium.

Product on the first screen at 390	yes ("Enter the burrow" at y=570–617 of 844)

Share card	present (og:title, og:image 1200×630, favicon, title), but it shows the old credit

Requirements

• "Change the footer credit to 'Built by @XiaoLingEr888'": met. index.html:283 and dist/index.html:283 read Built by @XiaoLingEr888 <b>Burrow Protocol / v2.0</b>.
• "by redeploying the latest main branch of wusjwu/echo-ledger": after review. I checked the source: upstream main is 82a7093 ("Credit: Built by @XiaoLingEr888"). Its only website change since the last release is that footer line, and telemetry.js is byte-identical to upstream. The deploy itself happens after review.
• "Change nothing else": met. The last commit's only site change is the footer line in index.html and its rebuilt copy in dist/; everything else is README, DESIGN and TESTING notes. Every website file in dist/ matches the source.

The idea: a canvas game about recording your route and replaying your echoes beneath a hamster wheel. The one visual device is the two-line headline "Small paws. / Parallel lives." with the second line in amber.

Finding (in .imd-findings.json)

• Medium, fidelity: the first screen and the share card still say "Built by 0xRicher". The title card's bottom row (index.html:149) is visible on the first screen at 390 (y=748), while the new footer credit sits below the fold (y=1116). The share image (assets/share.svg:11, which is what share.png shows) also says "Built by 0xRicher". Upstream main has no "0xRicher" anywhere, so the site disagrees with the branch it is supposed to redeploy.
  • Fix: change both strings to "Built by @XiaoLingEr888", re-export share.png and rebuild dist/. This changes only text, so it stays within "change nothing else".
  • Why not high: the brief's literal ask, the footer, is met. The builder left the title credit alone on purpose because of "change nothing else", and README says so. If the requester wants 0xRicher to keep a credit, that is their call.

Checks and limits

• Main interaction: I used it once in Chromium at 390. "Enter the burrow" starts play, the field and touch controls render, and nothing jumps around.
• Live data: the Squeekchain API calls failed with CORS errors from this sandbox, and the page showed its labelled "Simulated" fallback rather than fake live data. Whether the live API answers a real visitor depends on Squeekchain, so it isn't a finding.
• Not tested: I didn't run WebKit (Safari), so iPhone behaviour is unchecked.
• Unverified links: README and TESTING link to artifacts/ files that aren't in this tree. They may arrive with the job's inputs, so I didn't file them.

I changed no repository files; only the findings file and the probe screenshots in test/scratch/taste/ were written. I did not use the RPC endpoints, the pool skill, or anything about this machine.
