WHEN about to commit to a direction and want a sharp adversarial pass. Triggers: 'should we do X?', 'is this worth it?', 'pressure-test this plan/principle/vision', 'pick between A and B', 're-check the call we made two weeks ago', 'play devil's advocate'. Direct, not balanced. OUTPUT: verdict (do/delay/narrow/compare/kill), strongest case for and against, cheapest test. PAIR BEFORE: ticket-scoping (file the chosen path). Use post-hoc mode for older calls.
