* BKT (Bayesian Knowledge Tracing) Module
*
* Provides epistemologically honest skill mastery estimates using
* Conjunctive Bayesian Knowledge Tracing.
*
* Key concepts:
* - P(known): Probability that the student has mastered a skill
* - Confidence: How certain we are about the P(known) estimate
* - Conjunctive model: For multi-skill problems, correct = all skills worked,
* incorrect = at least one failed (blame distributed probabilistically)
*
* Usage:
* ```typescript
* import { computeBktFromHistory } from '@/lib/curriculum/bkt'
*
* const results = await getRecentSessionResults(playerId, 50)
* const bkt = computeBktFromHistory(results)
*
* // Access results
* console.log(bkt.skills) // All skills with P(known)
* console.log(bkt.interventionNeeded) // Skills that need attention
* console.log(bkt.strengths) // Mastered skills
* ```
