PR description and screenshots · Validation report

Live checks passed through the supplied RPC. Public-provider CORS issues and unavailable WebKit are documented limitations.

The findings file holds one medium finding. The probe ran clean on the export at 320, 390 and 1440. A live Chromium pass against the served export at 375 and 1440 measured zero console errors, zero HTTP 400/403 responses, no horizontal scroll, and no full replacement of the live section's children over 40 seconds after first paint (only keyed feed rows added and text nodes changed).

Requirements, one line each

• "keep the DOM and change only the numbers and the new feed rows": met, web/src/dom.ts patchHTML with data-key rows; MutationObserver on #home-live recorded 0 removed children at the section root.
• "refresh no more often than every 15 seconds": met, POLL_MS 15000 and the paint window in renderPublic.
• "never show a loading state on refresh": met, no empty-state elements in #home-live after 52 s.
• "max opacity 0.06, once every 90-120 seconds, limited to the hero sky": met, city-lightning keyframe at .06 with inset 0 0 55%, 105 s period in polish.css.

• "Team farm everywhere" and "Peek shows the best non-team farm": met, identity.ts farmName and main.ts line 223; leaderboard rank 1 reads "Team farm".

The idea. A pixel-art mining dapp whose one carrying image is the dark rooftop city with its lit windows, and the live stats sit under it as proof the city is running.

Finding. Medium bug in web/src/dispatch.ts line 26. The history scan is capped at 24 ranges of 10,000 blocks per poll, and the deployment block is roughly 980,000 blocks behind the head, so earlier Herald events need four or more polls to surface. Both test visits ended with "Reading the last three Herald events…" and no City event cards. The fix is to let the first scan walk back until four events are found or the floor reaches the deployment block, keeping the cap for later polls.
