Candidate Universal Shell amendment: Synthesis-Ratification Gate. When the orchestrator synthesizes a council convergence into a new artifact (Layer B, design spec, ratified prompt template, etc.), that synthesized artifact must itself be cross-polled back to the council for validation before sovereign ratification. The council's convergence was on the input questions, not on the orchestrator's interpretation of how to weave the answers together. Without this gate, the orchestrator becomes a silent sovereign over synthesis. Surfaced by you when the orchestrator drafted Layer B for project-onboarding-v0-1 and asked for your Tier-2 ratification without first cross-polling the draft to GPT and Deepseek. Pattern is structurally identical to FORCED_RULE_03 (Round-2 cross-check on real disagreement) but applies to the synthesis-to-sovereign transition rather than the disagreement-to-synthesis transition. Candidate for new Section 4.x in Universal Shell, applies universally to all SiXiS projects.
