 Quality-standard-2 blueprints are eligible for learner runs. Older blueprints
 remain stored only so signed questions and reports can be regenerated.

+Quality-standard-3 blueprints add Elo-adaptive difficulty. Each active objective
+must provide at least two families at every tier: foundation (850), standard
+(1050), advanced (1250), and expert (1450). The service targets an item about 70
+Elo below effective learner ability, approximately 60% expected correctness.
+Effective ability begins as an equal blend of overall and category question-bank
+Elo, then shifts toward dynamic objective Elo up to an 80% objective weight after
+10 attempts. Aggregate outcomes calibrate each case family's Elo over time.

 ## Content requirements

 - At least three curated case families per objective.
