Why: make the three approved CLIs the only active implementation and test routes
Evidence: adapter unit tests, configuration validation, diff check, and real marker probes for all three profiles
Impact: narrows project routing and fixes agy prompt binding for noninteractive execution
Refs: feature/goal-first-delivery
Why: Hide provider-specific noninteractive, model, permission, workspace, prompt, and output differences behind one adapter seam.
Evidence: Cursor observed red then 22 green config/adapter tests; the host replays them and whitespace checks during integration.
Impact: Adds deterministic direct-argv adapters and probes without launching providers or enabling project routing.
