• s/we check/{product-title} checks/
• Probably the last two sentences can be coalesced, something like: "... checks to ensure ... in namespace, and returns a 403 if that check fails." Tangentially, i'm not sure if naked "a 403" is ok. Maybe it's better to stick with the two sentences and say "If the check fails, the request fails with a 403 (Forbidden) error code." (presuming this is the 403 in question).
