Separate synthetic environment
BackBlind Case Showcase
Frozen pre-outcome read versus a controlled held-out outcome.
Frozen read
Evidence cutoff, contradictions, source demands, claim ceiling, and action candidate are sealed before outcome access.
Outcome held
The outcome remains unavailable until explicit governed release through the existing blind-case authority.
Blind case lifecycle is API-governed. This showcase does not expose a release control until a real governed UI is implemented and tested.
