Do you have any sources that the Ordeals and Rites of Maturation are different things, or is that a headcanon/theory?

Dammek is going through the Rites of Maturation at 7 sweeps, and he’s still going to be around after them, if he survives. That’s much younger than Chahut, Skylla or Mallek, who’re set to undergo the Ordeals to leave Alternia relatively soon.
