Discovery pipeline governance — phase gate management, resource orchestration, dependency control, and proposal QA validation across the entire discovery pipeline. Replaces former project-program-management (not generic PM, specific to discovery pipeline). Use when the user asks to "track the discovery", "govern the pipeline", "validate the proposal", "run governance check", "check phase dependencies", "coordinate resources", or mentions pipeline governance, phase gates, proposal readiness, milestone tracking, or cross-phase dependency management. Works as the structural glue that holds the entire discovery pipeline together — from Phase 0 through Handover.
