The diagnostic that separates compounding from collecting is whether the post-collection state contains something the pre-collection state did not — something the user (or anyone) could not have gotten from the cultural ratchet alone. If yes, it was a ratchet click; if no, it was a highlight. A journal entry about a coffee meeting is a record, not an increment — the next reader could have written it from primary sources alone. A synthesis page that draws a cross-source finding neither source contains in isolation is an increment because it could not have existed without the click that produced it.
