Adaptive elicitation engine for the Requirements Analyst stage. Routes between Socratic probing, pre-mortem, ambiguity detection, and assumption mining based on request signals. Enforces a coverage map (Purpose / Needs / Limits / Expectations / Context / Risks / Acceptance / Unknowns) so no axis goes unasked. Also used in a reduced "plan-stage pre-mortem" mode by workflow-planner.
