How it decides

Concentric rings of data converging on a single point

The voice is the commodity. The decider is the thing no one else has.

Before it looks for the best option, it removes every option that isn’t allowed for this student, and only weighs what’s left. The wrong move never even competes for the win. Here is everything it decides with, and how.

What it decides with

  • The student, over timeA living picture of what they are trying to do, where they left off, and the real limits they live inside: time, money, energy. It follows where they are heading, not only what they typed.
  • The course and the institutionVerified material, rules, programs, deadlines and offices.
  • Live systemsEnrollment, holds and activity, under a strict order of truth: a live record beats a document, which beats a claim.
  • What worksCurated best practices for students in this situation, used as a guide, never as an override.

How it decides

  1. 1Remove what isn’t allowedFour hard gates, checked every time before anything is scored: feasible, safe, legal, legitimate. If a gate can’t be confirmed, the answer is no. A forbidden move never competes.
  2. 2Choose the best of what’s leftToward the student’s goal. Belief is weighted by how trustworthy the evidence is, and follow-through is modelled as capacity × willingness × coordination, so it works on whatever is holding the student back. It keeps learning the student, outside the fixed core that sets the limits.

What comes out

  • Actexplain, give a hint, take the next step
  • Askonly what it needs to decide well
  • Offer optionswhen the trade-off is genuinely open
  • Honest no, or a personif it doesn’t know or shouldn’t act, it says so, or it hands the case to a person on your staff. Signs of distress go to your wellbeing team, and it never follows up unless the student does.

It is designed so every decision is written to a record your team can replay: what was weighed, what was set aside, and why.
