It was this suggested edit that got applied: https://electrical.codidact.com/posts/suggested-edit/11. Likely you changed the tags or title, hence it isn’t shown. However, this is just a theory I can’t verify (right now).

Thanks for posting this. I saw the activity too, then went looking for what change, but couldn't find it.

Part of the problem is related to this bug: https://meta.codidact.com/questions/277308

Is "The site claims " correct, strictly speaking? There is a timestamp that I agree at least strongly implies that, but if when a proposal came into effect is useful information, it could be reasonable for a single stamp to favour 'implemented' over 'suggested'. Maybe there should be two stamps, or at least clarification of the significance. (The latter may exist without my having noticed it.)

@pnuts Actually, the time when someone suggests an edit also shows up in user activity as "Suggested Edit" and also says whether the edit was "helpful" (accepted) or "declined". The existence of the latter information makes the "Edit" activity for when the edit was accepted kind of pointless imo

@Moshi Thank you (again!). Now with improved understanding, maybe in such cases edit from rather than edit by would be an adequate fix? I am fairly certain elsewhere this would be [status-bydesign]. BTW most of my suggested edits are neither "helpful" nor "declined" - there is also "pending".
