Evidence and limits
Finding: AI improved speed and quality on tasks within its capability frontier, but reduced correctness on a task outside that frontier even when the tasks appeared similarly difficult.
Impact: Strengthen capability-boundary detection and task-specific evaluation. Reject provider-level capability claims as sufficient routing evidence.
Boundary: The frontier was constructed for one model, occupation, and task set. Next: how can a workflow detect boundary crossings before an apparently competent output becomes authoritative?
Flags: one occupation; frontier defined by tested model and tasks
Record State: Catalog review recorded; not a performance endorsement
What was reviewed: Structure and relevance screened; not a full evaluation
