I've added another guidepost  (https://www.openstreetmap.org/node/11781794485) to the Green Link Walk (approx location). I've seen another map show the route going the park at Clapton Square, but this guidepost would indicate that it doesn't.

I've walked it via the park and it's very much not step-free at either side of the park. The route is billed as being step-free, so I'd be very confident that it doesn't go through the park but passes the guidepost instead.

(Not step-free to cross the road at https://www.openstreetmap.org/way/1078872732 either, but that does seem to be the signed route).
