[subtype] Autophagy-Lysosome Pathway|Lysosomal catabolism|Lysosomal lipid catabolism|Lysosomal sphingomyelin/ceramide metabolism|Lysosomal ceramidase
status=no_mapping scope= GO=[]
rationale: Reviewed as a mixed lysosomal ceramide/glycosylceramide hydrolase bucket containing ASAH1, GALC, and GBA1. The current GO cache lacks a non-obsolete ceramidase term that safely covers all members, so no direct universal mapping is made.
[type] Autophagy-Lysosome Pathway|Lysosomal catabolism|Lysosomal lipid catabolism|Lysosomal sphingomyelin/ceramide metabolism
status=no_mapping scope= GO=[]
rationale: Reviewed as a mixed sphingomyelin/ceramide metabolism container. The child leaves include enzymes and activators with different molecular functions, so direct propagation from the container would lose specificity.
[group] Autophagy-Lysosome Pathway|Lysosomal catabolism|Lysosomal lipid catabolism
status=context_only scope=too_broad_to_propagate GO=[GO:0016042 lipid catabolic process]
rationale: This group is a lysosomal lipid-catabolism context, but it mixes lipases, phospholipases, sphingolipid enzymes, and activators. Specific molecular functions are mapped at narrower leaves.
[class] Autophagy-Lysosome Pathway|Lysosomal catabolism
status=no_mapping scope= GO=[]
rationale: Reviewed as a broad lysosomal-degradation container. The subtree includes carbohydrate, lipid, protein, nuclease, phosphatase, sulfatase, and environment-regulation roles, so mapping should occur at the enzyme or process subtype level.
[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.

PN-node mapping records (path + ancestors):
[group] Autophagy-Lysosome Pathway|Autophagic lysosome reformation|Specific function in autophagic lysosome reformation unknown
status=no_mapping scope= GO=[]
rationale: This PN group explicitly states that the specific role within autophagic lysosome reformation is unknown. That makes GO propagation unsafe until a narrower mechanistic interpretation is available.
[class] Autophagy-Lysosome Pathway|Autophagic lysosome reformation
status=context_only scope=too_broad_to_propagate GO=[GO:0007040 lysosome organization]
rationale: Autophagic lysosome reformation is the lysosome-regeneration phase that follows autolysosome formation and cargo degradation. As a class, it is better aligned to lysosome organization than to generic autophagy, but the PN members are mechanistically mixed across membrane remodeling, tubulation, product efflux, and unknown late-stage roles, so class-level propagation would still over-annotate.
