Curation history
- Codex; review-causal-graph; Reviewed every native GO-CAM fact; preserved precise input/output, causal, location, membership and complex-part relations with traceable structured source evidence. Kept distinct generic physical instances and recorded source-scope exclusions in the cohort review ledger. Reviewed exact Complex Portal composition, source evidence grades, and independent physical complex locations.
- Codex; review-complex-composition; Reviewed exact Complex Portal composition, source evidence grades, and independent physical complex locations; reused existing proteins through reviewed UniProt SGD cross-references.

- EDIT — Audit causal activity compartments and preserve scoped protein location evidence
Reviewed all 14 activity location assignments and 13 mapped physical proteins against reviewed S288C UniProt release2026_03 location/function/caution batch SHA256 95f72dcc644358c480e0e59f996cf88533558b5fa4256460a030e0a1eaf9678d. Added 15 independently supported location edges and quarantined 3 generic cytosol source assertions. Mapped physical protein locations via exact SGD cross-references; retained source ECO grades, molecular form and conditional notes. Physical protein location alone never generates activity location. Explicitly inspected functional assertions support bounded activity projections. Every original activity location and exclusion is recorded in reports/causal_graph_review/gocam-location-review.json. No independent location annotation is treated as an evidence gap, not a negative result. Cytoplasm is not narrowed to cytosol. Microsome fractions are not projected as in-vivo organelles. Semantic validation passed all85 records;4 independent source-role acceptance tests passed.

- EDIT — Resolve distinct folate states and MET13 nucleotide specificity
Reviewed all14 activities against pinned UniProt2026_03 catalytic source and Rhea139. Corrected five methenyl endpoints formerly merged into methylene CHEBI20502; corrected MET13 NADPH/NADP using PMID11729203 while retaining independently supported MET12 NADH. Quarantined18 unsupported directed folate-flow assertions whose displayed chemical sides do not match; preserved full original edges in reports/causal_graph_review/folate-inositol-chemistry-review.json. No reaction reversal or compartment transport inferred. Semantic validation and six independent chemistry regression tests passed.
