PN placement: 1 row, ALP — Autophagosome closure maturation and lysosome fusion → "Specific function in autophagosome maturation and lysosome fusion unknown". PN-node mapping: leaf group=no_mapping; class=context_only→GO:0016236; branch=no_mapping. No GO propagates. PN Notes: activator of CDK5 required for phosphorylation of ACN (acinus).
Consistency: Consistent. Same "unknown" residual bucket and same Drosophila eLife paper as CDK5, justified only by CDK5R1's role as the CDK5 activator. The review keeps the lone autophagy row (GO:0016241 regulation of macroautophagy, NAS, PMID:21499257) as KEEP_AS_NON_CORE, with the explicit reasoning that the human paper assayed CDK5→SH3GLB1, not a CDK5R1 perturbation — so CDK5R1's autophagy involvement is inferred via complex membership, not directly tested. This honest "complex-level context" framing matches PN's no_mapping/unknown placement exactly. No contradiction.
PN story / NEW pressure: Already captured; PN over-reaches no further than CDK5. The defensible-but-indirect GO:0016241 is present (held non-core). No human evidence supports a CDK5R1-specific autophagosome-maturation term, so no ADD. The conserved Acinus hypothesis is routed to a suggested_question/experiment (CDK5R1-specific depletion/rescue in induced-autophagy assays).
Mapping strategy: No change. no_mapping is correct — CDK5R1 is a regulatory subunit whose only autophagy link is via CDK5; propagating GO:0016236 would be doubly indirect. CDK5R1's inclusion in the node adds no new GO-mappable shared function.
Evidence alignment: Divergent in the same way as CDK5. PN cites the Drosophila Cdk5-Acinus-S437 eLife paper; the review's autophagy row rests on human PMID:21499257 (SH3GLB1), which PN does not cite, plus its own notes flagging the inference gap. Convergent on neither autophagy paper directly, but the review is the more cautious.
Verdict: Fully consistent; correctly more conservative than CDK5 (KEEP_AS_NON_CORE vs ACCEPT) given the inference is one step removed. No edits needed.
