Reservation Roster
The running register that tracks which roster point each appointment consumed, ensuring reservation percentages hold across recruitment cycles.
The roster carries forward between recruitments: if a cycle ends mid-sequence, the next notification resumes from that point rather than restarting at one. This is why two consecutive cycles of the same exam can offer a category different vacancy counts. Candidates never see the roster directly; it operates inside TNPSC's allotment after the merit list is drawn.
