It is not a voter-by-voter analysis it could be argued a state's election was conducted in manner that clearly allowed multiple violations of the law.

Note my post 22. If E Check were required but not run it would be clear there were multiple violations in the time between an election and acceptance of electors. Though it should be used prior to elections, 365 days a year.

As you point out, there are a number of instrumentalities a state can use to verify voter eligibility.

The sole issue, of course, at the Joint Session in the January following each presidential election is whether the certification from each state of its federal election results is valid.

Each state has the burden of proof that, as it certifies, its elections were held in conformance with all state and federal laws.

It is an easy matter to show where a state allows noncitizens to register to vote (via DMV, etc.) but then makes no effort to assure that state voter is not excluded from the federal election.

Essentially, if a state does not have in place such safeguards prior to the 2025 Joint Session, but unabashedly has proceeded as normal with no regard to federal law there can be no credible certification.

This just off the top of my head without briefing the many fine points.
