KB1 graph: separate field dechlorination, community cofactor support and external-strain rescue #1523

Record:KB1_Chlorinated_Ethene_Dechlorinating_Consortium.yaml (000132),3 nodes/2 arrows.

Preserve positive field bioaugmentation (PMID12523427), vitamin-free community support (PMID31441646) and controlled Sporomusa KB1 DMB-guided cofactor experiments (PMID23479750). The latter uses Dhc BAV1/GT/FL2, not established as the record's KB1 recipient population; FL2 is not universally complete-to-ethene. Remove that cross-study arrow to the KB1 endpoint, retaining the donor observation with explicit partner limits. Bound Acetobacterium support-to-dechlorination as PARTIAL for exact mediation/field generalization, not a proven exclusive transfer route. Remove unproved SYNTROPHY and transporter-mechanism overclaims. Canonical IDs/labels remain unchanged, with species grounding a separate follow-up.

Full2013 and2019 primary main texts read;2019 Tables1-2/Figures2-5 visually inspected. Field study abstract only. No separate supplements/raw data. Existing-node repair only; no Edison spend or new graph structure.

Dedup:827 all-state issue titles/bodies, broader synonyms,38 ignored/hidden local matches and relevant source/history/test contexts; not every comment/PR. Whole records reviewed. Self-adversarial review is not independent approval. Keep repair issues open until protected-main merge; metadata/provenance followups remain open until separately resolved.
