There has always been a problem with the {{harv}} and {{sfn}} families of templates: except that every link that is created by these templates is tested at creation, editors don't know if the link works. A remedy for that has been user-scripts like User:Ucucha/HarvErrors. But, not all editors use that script so broken harv links can go undetected for a long time. At the moment, there is prospective bot that would mark broken-link harv templates by adding {{broken footnote}} after the broken-link harv template.
I have another possible solution. I have created a lua module that extracts reference linking data from cs1|2 and vcite templates. I have modified Module:Footnotes/sandbox to use the extracted data to determine if:
- the harv template does not have a matching citation template
- more than one citation template matches the harv template
when either of these conditions exists, the harv template emits an error message.

The sandbox module collects various items from the citation templates in the article's wikitext and assembles them into a list of CITEREF anchors that each harv template can inspect:
- when
|ref=harveither explicitly (cs1) or implicitly (cs2), the sandbox module builds aCITEREFfrom the cs1|2 parameters:- name sources:
|contributor=,|author=,|vauthors=,|editor=and|veditors=, and their aliases (where they exist) - date sources:
|year=,|date=,|publicationdate=, and|publication-date=(in that order).
- name sources:
- when
|ref=or{{sfnref}}|ref=, the sandbox module builds a{{harvid}}CITEREFfrom parameters in those templates and adds the result to the list. - when
|ref=CITEREF<name-date>, the sandbox module adds that text (absent theCITEREFprefix) to the list. - when
|ref=<anchor-identifier-text>, the sandbox module adds that text to the list – to match a harv template's identical|ref=<anchor-identifier-text> - when
|ref=is empty or omitted and|mode=cs2, the sandbox module acts as if|ref=harv - when
|ref=none, the sandbox module skips the citation becauseCITEREFanchor creation specifically suppressed in cs1|2
Alas, there is a flaw. Because the sandbox module reads article wikitext, and because wrapper templates often set cs1|2 parameter values inside the template, so the sandbox module emits a false error message for wrapped templates ({{cite EB1911}} wraps {{cite encyclopedia}}:

So that false error messages don't linger in an article, I have added |ignore-err= to the harv templates so that false error messages may be suppressed ({{cite DNB}} wraps {{cite encyclopedia}}:
