[type] Autophagy-Lysosome Pathway|Autophagosome closure maturation and lysosome fusion|Class 3 PI3K complex 2, direct|Class 3 PI3K complex 2 component
status=mapped scope=ok_for_propagation_to_go GO=[GO:0034272 phosphatidylinositol 3-kinase complex, class III, type II]
rationale: This PN type denotes component membership in the direct class III PI3K complex 2 module used during autophagosome maturation and lysosome fusion. The corresponding GO complex term is the right propagation target.
[group] Autophagy-Lysosome Pathway|Autophagosome closure maturation and lysosome fusion|Class 3 PI3K complex 2, direct
status=context_only scope=too_broad_to_propagate GO=[GO:0035032 phosphatidylinositol 3-kinase complex, class III]
rationale: Reviewed as a class-III PI3K complex context or regulator bucket. This node is useful for curator interpretation, but it should not project cellular-component membership; only explicit complex-component leaves propagate to GO complex terms.
[class] Autophagy-Lysosome Pathway|Autophagosome closure maturation and lysosome fusion
status=context_only scope=too_broad_to_propagate GO=[GO:0016236 macroautophagy]
rationale: This class is a late macroautophagy context, but the subtree mixes docking, fusion, localization, membrane-composition, and unknown late-stage roles. The class-level relation is useful for display while propagation is restricted to narrower mechanism nodes.
[branch] Autophagy-Lysosome Pathway
status=no_mapping scope= GO=[]
rationale: Reviewed as the top-level PN branch. It is a project taxonomy umbrella rather than a direct GO assertion; all propagation must come from manually curated child nodes.
