The knowledge constellation

One core of truth. Many visible pathways.

Each illuminated point is a concept with a single canonical identity across languages and curricula. The lines between them are real prerequisites — and the rings show how deep your mastery reaches.

How mastery is proven

Evidence moves through explicit criteria to a recorded, defensible decision. Scores alone never decide mastery.

STEP 01EvidenceWork captured against a published target.

STEP 02CriterionAn explicit standard the evidence is judged against.

STEP 03ReviewHuman judgement — not an automated pass.

STEP 04MasteryA defensible, recorded decision.

A map, not a rank

Readiness is shown so you can see the next reachable step — it is never used to label a learner.

How the journey unfolds

Every step has a reason.

DiscoverA readiness diagnostic maps what you already hold.

ConnectPrerequisite edges reveal the exact path that unlocks the goal.

PracticeThe method adapts to the subject and the target, not to a grade label.

DemonstrateYou submit evidence that a reviewer can actually reason about.

MasteryMastery is decided from evidence — never from a completion bar.
