Static Methods

canSelfOverride(String current, String target) → bool

Whether a self-override from current to target is allowed. Users can skip forward at most 2 levels, and never directly to 'mastery'.

effectiveMastery(List<String> childMasteries, [String? ownMastery]) → String

Compute effective mastery for a parent topic from its children's mastery values. Returns 'in_progress' when children have mixed mastery levels.

masteryIntFromLabel(String mastery) → int

Maps a mastery label to its 0..5 index on the ramp. The synthetic 'in_progress' state returns 0 — callers that want the parent-rollup appearance should pass inProgress: true to MasteryRing instead.

nextMastery(String current, String sessionMode) → String?

Returns the next mastery level if the completed session mode matches the expected progression, or null if no advancement applies.

validationModeForLevel(String targetLevel) → String?

Returns the session mode used to validate a given mastery level.

Constants

levels → const List<String>

Ordered mastery levels from lowest to highest.
