SFB93/Dhc195 graph: distinguish recipient activity and exact-pair acetylene rescue #1388

Dehalococcoides_Pelobacter_Acetylene_TCE_Coculture.yaml (000184).

The reductive-dechlorination node is labelled as Dhc195-to-SFB93 CROSS_FEEDING without evidence of reverse nutrient transfer. The relief node describes the ANAS enrichment but points to the strain-195 phenotype, and COLONIZATION_FACILITATION is not the measured process.

Primary PMID:28075122, Results and Figure 2 caption, directly tests recovery of acetylene-inhibited strain 195 after SFB93 addition. Retain that positive arrow with exact-pair scope, rather than importing ANAS methanogenesis or deleting demonstrated rescue. The cached abstract rescue phrase refers to ANAS, so mark its exact-pair support PARTIAL and document the primary-body access separately. Do not restore paywalled text; #765 remains the separate evidence-debt follow-up. Preserve the curated Syntrophotalea GTDB pin (#384). All three nodes and two arrows can be retained.

Deduplication: 717 all-state issue titles/bodies, broader organism/biochar/acetylene/CO synonyms and ignored/hidden-inclusive scoped local review/history/research/tests/scripts.
