Error tags to use after real attempts
Tag the cause, not just wrong/right: - knowledge gap; - vocabulary/confusion pair; - sequence/process; - architecture-role confusion; - missed qualifier; - role/responsibility; - poor elimination; - overthinking; - changed answer; - time pressure; - confidence mismatch; - source-lookup failure.
Artifact 08 stays empty until performance exists. Repeated misses, slow decisions, and confidence/timing patterns—not predicted weaknesses—should populate it later.
