Found what appears to be a minor mistake you may want to fix: "This means that a dangling reference easily results in a reference to the wrong column" should probably be "... a reference to the wrong row". (In the paragraph about SQLite's tendency to re-use ROWIDs).

Suggestion: post this on https://sqlite.org/forum/forum - the SQLite team monitor that forum closely and I've had some really great answers from them to questions or suggestions in the past.
