ABD friendly doctorate with max transfer RA preferred under 15k finish fast

[Docu]

I’m trying to understand how ABD (All But Dissertation) is typically verified for admission into ABD completion programs.

1. Is “ABD” or “doctoral candidate/candidacy” ever shown on an official transcript, or is it usually not listed explicitly?
2. If it’s not on the transcript, what do schools usually accept as proof — just the number/type of doctoral credits, or do they require an official letter from the university confirming candidacy/comps/dissertation status?
3. What specific milestones do ABD completion programs typically look for (e.g., comprehensive exams passed, advancement to candidacy, proposal approved, dissertation credits, etc.)?
4. If a transcript shows a doctoral program plus a milestone master’s (like an MPhil) but no doctorate awarded, is that enough for ABD programs, or do they still need a candidacy verification letter?

If anyone has gone through ABD completion admissions (or evaluated transcripts for it), I’d really appreciate what documentation worked and what didn’t.
