I completely understand, believe me I get it—but based on everything I've seen, it's a hopelessly romantic view. If I've learned one thing, it's that people are going to "come up with their own narratives", as you aptly put it, no matter what we do. Adding energy into that would only create more pressure and demand on a system which is maxed out already.
Making this mistake would lead to more argument, not less—the opposite of what was intended. It would simply reproduce the same old arguments at a meta level, giving the fire a whole new dimension of fuel to burn. Worse, it would skew more of HN into flamewars and meta fixation on the site itself, which are the two biggest counterfactors to its intended use.
Such lists would be most attractive to the litigious and bureaucratic sort of user, the kind that produces two or more new objections to every answer you give [1]. That's a kind of DoS attack on moderation resources. Since there are always more of them than of us, it's a thundering herd problem too.
This would turn moderation into even more of a double bind [2] and might even make it impossible, since we function on the edge of the impossible already. Worst of all, it would starve HN of time and energy for making the site better—something that unfortunately is happening already. This is a well-known hard problem with systems like this: a minority of the community consumes a majority of the resources. Really we should be spending those making the site better for its intended use by the majority of its users.
So forgive me, but I think publishing a full moderation log would be a mistake. I'll probably be having nightmares about it tonight.
