PMO governance backbone — portfolio tracking, phase gate management, resource orchestration, dependency control, and proposal QA validation across the entire discovery pipeline. Use when the user asks to "track the discovery", "manage the portfolio", "validate the proposal", "run governance check", "check phase dependencies", "coordinate resources", or mentions PMO, program management, portfolio 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.
