    Review complete. The site is clear to host: nothing in the export meets the critical or high bar, and the findings file at the repository root holds four advisory entries.

    What was read. Every file that will be served, which is all six files in dist/, plus the two check scripts, the preview server, README, brief and package manifest. The SHA256SUMS match the tree. The repository's own checks both pass. Chromium cannot start on this machine because its system libraries are missing, so runtime behaviour was confirmed with Node against the engine and the live Squeekchain API instead.

    What the scripts do. The only network call in application code is a 5-second poll of the Squeekchain status endpoint in Live mode. The response is validated field by field and never executed or inserted as HTML. There is no wallet code, no signature or approval request, no password or seed-phrase field, no iframe, eval, dynamic import, redirect or obfuscation. The site presents itself as Squeek Express, a game built on Squeekchain data, and Squeekchain is a real, reachable project whose API returns exactly the fields the engine expects.

    Findings written to .imd-findings.json:

    • Medium. The stylesheet imports Google Fonts, so every visitor contacts Google on every page load with no disclosure anywhere on the site.
    • Low. The stream-view dialog says a sign-in may be required. No sign-in exists, and the README says so.
    • Low. Expedition fields in a saved profile are not validated. A crafted localStorage entry renders its name as HTML in the expedition dialog, and a non-numeric reward corrupts the save so the profile silently resets on reload. Same-origin only, not reachable by a plain visitor.
    • Info. A record of the live API poll, where it is disclosed, and the confirmation that the live response was accepted without crediting energy.

    Each snippet was checked against its file and line, and no tracked file was changed.

    • mediumStylesheet loads Google Fonts from fonts.googleapis.com on every page load without disclosuredist/style.css:1

      The only stylesheet, dist/style.css, starts with a CSS @import of Google Fonts. Every visitor of every page (welcome gate, game, and ?mode=overlay stream view) therefore makes a request to fonts.googleapis.com and then fonts.gstatic.com before any interaction, sending their IP address and user agent to Google. Nothing on the site, in the help modal, or in README.md mentions this third-party contact; the footer and welcome card only say progress is saved in the browser.

      It is a stylesheet, not script, so it cannot execute code and the page renders with fallback fonts if the request is blocked, which is why this is advisory (tracking without disclosure) and not a hosting blocker. It also makes an IPFS-pinned site depend on a third-party host for its typography.

      Serve dist/ (npm start) and open http://localhost:4173/ with the browser Network tab open, before entering a name.

      Expected for a self-contained pinned site: requests only to the site's own origin (plus the documented api.squeekchain.com call in Live mode).

      Actual: a request to https://fonts.googleapis.com/css2?family=Space+Grotesk... followed by font file requests to fonts.gstatic.com on every load.

      Confirmed statically: grep -rn 'https?://' dist/ lists exactly three external URLs, this one, the documented API endpoint (dist/app.js:30), and the documentation link (dist/app.js:38).

    • lowStream view dialog tells visitors a sign-in may be required, but the site has no sign-indist/app.js:39

      The 'Stream view' modal text in dist/app.js line 39 still says 'This private preview may require a sign-in that OBS cannot complete.' Nothing in the export has any sign-in: the only form is the local engineer-name gate in dist/index.html (no password field, no auth request anywhere in app.js, engine.mjs, profiles.mjs or scene.mjs), and README.md explicitly states 'The package does not depend on ChatGPT or its sign-in screen.'

      The sentence is leftover copy from an earlier private preview and is misleading on the public site, though it does not ask the visitor for anything and does not affect the hosting decision.

      Serve dist/, open the page, enter any name such as 'tester', then click the ▣ 'Open stream view' button in the control dock under the canvas.

      Expected: a description of the overlay that matches the shipped behaviour (no sign-in exists; ?mode=overlay opens directly).

      Actual: the dialog displays 'This private preview may require a sign-in that OBS cannot complete.'

      Opening http://localhost:4173/?mode=overlay directly shows no sign-in of any kind.

    • lowSaved-profile expedition fields are not validated: name is injected into innerHTML and a non-numeric reward corrupts the save so it resets on reloaddist/app.js:36

      validate() in dist/engine.mjs line 17 checks expedition.hamster and expedition.remaining only; expedition.name, coins, gear and crystal are accepted as whatever the stored JSON contains. migrate() at line 16 only overwrites name when expedition.id matches a known expedition. dist/app.js line 36 then concatenates e.name straight into innerHTML of the expedition modal, and claimExpedition() (engine.mjs line 34) does s.coins+=e.coins without a type check.

      Consequences, confirmed by running the engine in Node: (1) markup in expedition.name is parsed as HTML in the dialog, which is a same-origin self-XSS since the only writer is localStorage of this origin; (2) a string coins value turns s.coins into a string, validate() then returns false, and readProfile() in profiles.mjs falls through to initial(), so the player's whole profile for that mode silently resets on next reload.

      Both require the stored profile to have been edited (by the player, a browser extension, or any other site that shares the same origin, which matters if the site is ever served from a shared path-based IPFS gateway). Advisory only; it is not reachable by a plain visitor and is not a hosting blocker.

      Node, from the repository root: import {initial,migrate,validate,claimExpedition} from './dist/engine.mjs'; let t=initial(); t.owned.push('mint'); t.expedition={id:'bogus',name:'',hamster:'mint',remaining:0,ready:true,coins:'1e9',gear:0,crystal:0}; let m=migrate(JSON.parse(JSON.stringify(t))); Expected: migrate returns null or sanitises the record.

      Actual: migrate returns the state with name '' intact; after claimExpedition(m), m.coins is the string '01e9' and validate(m) is false.

      In the browser: serve dist/, enter name 'tester', then in DevTools run localStorage.setItem('squeek-express-profile-tester-practice', JSON.stringify(Object.assign(JSON.parse(localStorage.getItem('squeek-express-profile-tester-practice')),{owned:['cinnamon','mint'],expedition:{id:'bogus',name:'',hamster:'mint',remaining:0,ready:true,coins:'1e9',gear:0,crystal:0}}))); reload, re-enter 'tester', open 'Plan an expedition' from the Expedition Crew box: the img element is created from the stored name.

      Click 'Collect expedition rewards', reload, re-enter the name: the profile has reset to the starting state (0 stars, 1 crew member).

    • infoLive mode polls api.squeekchain.com every 5 seconds; the only external script contact, disclosed and data-onlydist/app.js:30

      For the record of what the hosted scripts do: dist/app.js line 30 is the single network call in the application code. In Live mode (or ?mode=overlay) it GETs https://api.squeekchain.com/v1/status every 5 seconds with an 8-second timeout and passes the JSON to measure() in dist/engine.mjs line 23, which validates freshness, observedAt, counterEpoch, installationId, rpmMilli and cumulativeWorkUnits (BigInt, delta capped at 10000) before granting energy.

      The response is never executed or inserted as HTML; only derived numbers reach the UI. The call is disclosed in the help modal (app.js line 38) and README.md. I fetched the endpoint: it is a live Squeekchain service returning exactly these fields, and measure() accepted the response with rpm 0 and set a baseline without crediting energy.

      No wallet, signature, approval, seed phrase, password, iframe, eval, dynamic import, redirect or obfuscated code exists anywhere in dist/. The site presents itself as 'Squeek Express', a game built on Squeekchain data, not as Squeekchain itself. Nothing in the export meets the critical or high bar.

      Serve dist/, enter a name, click LIVE FEED in the header.

      Expected and actual: the browser Network tab shows a GET to https://api.squeekchain.com/v1/status repeating every 5 seconds, status label changes to 'LIVE · THE REAL HAMSTER IS RESTING' or '...

      IS TURNING', and no other third-party host is contacted apart from the Google Fonts request already reported.

      Static confirmation: grep -rnciE 'eval(|new Function|<iframe|document.write|atob(|import(' dist/ returns 0 for every file.
