We are assessing whether a public-model study of untreated baseline total PTEN protein is feasible without opening assay matrices. We are not asking for files yet and do not want assay values or participant/donor information.

Could DepMap support a complete model-only projection that provides:

- safe public model identity plus typed lineage relations and closure-only related-model nodes;
- one `RESOLVED`/`UNRESOLVED` determination per target model for PTEN RNA, absolute copy number, mutation-callability under a frozen rule, and total PTEN `P60484`, with a Boolean only when resolved; and
- value-free artifact, baseline-condition, assay, and total-PTEN identity?

Could DepMap also authenticate such a package through an independently published provider key and attest known duplicate/mirror/derived/shared-source relations between contributing releases? If feasible, we would first agree a separate exact wire schema and signature profile. Please do not generate or attach files at this stage. Confirmation that any required element cannot be supported would also answer the question.
