+Remove Meta-shape `payload_must_contain` over-fit from 3 storyboards (sales-social, audience-sync, signal-marketplace) and extend cross-step `identifier_paths` echo to signal-marketplace, sales-non-guaranteed, creative-ad-server, and audience-sync delete step. Non-protocol change — storyboard conformance harness only.
