• Product enhancement is currently encoded as directed cross-feeding of cellulose. Represent the measured consortium output separately from the proposed soluble-sugar supply.
• Preserve the strong evidence for GD17 substrate conversion and JN4 growth suppression, but the COMPETITION enum requires reciprocal harm, not merely resource competition.
• Growth estimates combine protein, optical-density calibration and genomic composition, not direct viable counts. Preserve the glucose/transcription and stimulant controls while qualifying mediator attribution.
• Account for all three nodes and both arrows; distinguish improved products from cellulose utilization and from the supplemented rebalancing arm.

No new structure is proposed. Guarded graph-only repair, append-only history, complete decisions and source-based self-adversarial review required. Unrelated metadata is a separate followup.

Deduplication: all 678 prior issue titles/bodies searched; relevant #639, #529, #749, #752 reviewed. Ignored/hidden local reports, history, research and tests included. No duplicate exact graph finding in that scope; issue comments not exhaustively searched.
