S. wolfei/Dhc195 graph: separate recipient respiration from modeled aggregation support #1389

Dehalococcoides_Syntrophomonas_TCE_Dechlorination_Coculture.yaml (000183).

Recipient dechlorination is labelled as reverse CROSS_FEEDING. Aggregation is a joint observation, not demonstrated unidirectional COLONIZATION_FACILITATION. Primary PMID:25576615 reports SEM aggregates and calculates hydrogen flux using a diffusion model; it does not selectively perturb aggregation to prove necessity. Preserve three nodes and two arrows, with the aggregation mechanism PARTIAL and its modeling evidence COMPUTATIONAL, distinct from measured microscopy.

Keep butyrate-fed syntrophy distinct from crotonate comparisons; VC-to-ethene conversion is cometabolic, and donor-limited hydrogen thresholds are separate assays. The 2016 follow-up has exact-Dhc qRT-PCR but uses M. hungatei for protein/complex assays; do not pool them or infer gene necessity. Any new carbon-monoxide structure is a separate open research task.
