the countdown to PPR starts with seldec (not third line) when they initiate activities related to admissibility assessment. Meds are just an element of this process and e-CAS can show if it is completed, but lacks in this capacity in regards to crim, sec, hirv, misrep, org. crim and other assessments that can (and in most cases will) be ongoing. So, if you see the third line, it doesn't presuppose that all other activities have also been finalized. The only signal that would trigger such alarm is RFV abbreviation in GCMS file.
