Short verdict: Keep. uORF biology is strong and the ATF4/GCN4 examples are appropriate; phrase effects as often repressive but sometimes enabling conditional translation.
What the current graph claims
Node definition: Upstream open reading frames that intercept scanning ribosomes and tune main ORF translation, including stress-dependent reinitiation logic.
What is strongly supported: uORFs are widespread and regulate translation initiation by ribosome diversion, reinitiation, leaky scanning, and start-codon context; ATF4/GCN4 mechanisms are canonical.
What is context-dependent: Effect size depends on uORF length, start context, distance to main ORF, termination/reinitiation competence, and cell state.
What is weak, controversial, or assay-biased: Ribosome profiling can overcall translated uORFs without careful harringtonine/lactimidomycin/ORF validation and conservation/proteomics support.
What may be duplicate biology under another name: Overlaps with BRAKE and FORGE.
Missing or excessive graph structure
Missing edges: Add DECOY -> CENSOR/TIMER? uORFs and translation termination can affect NMD for some transcripts.
Excess edges: DECOY -> FORGE inhibitory is mostly correct but should allow activating/conditional uORFs.
Candidate splits: No split.
Candidate merges: No merge.
Candidate renames: uORF.
Recommendation
Concrete graph change, if any: Keep; wording should include activating/conditional uORFs, not only decoys.
Concrete technical-notes/blog wording change, if any: Mirror the graph recommendation in the glossary and relation catalogue, and explicitly mark the confidence/caveat where the claim is context-dependent or assay-sensitive.
