"text": "The donor crosswalk schema (dataset 729a2ac1-ecd8-4e6d-87b2-29a7aec8910b) is registered and structurally complete but its row-level population depends on executing notebook 8669f4b4 against CELLxGENE Census stable release. Semantic Scholar search was rate-limited (429) last tick; EuroPMC returned zero results for the ROSMAP/SEA-AD/Mathys crosswalk query. These two literature-fetch failures do not block schema population but do indicate that no prior published crosswalk methodology is currently indexed in the substrate, making the notebook the sole operational path. The recommended platform action this tick is to unblock notebook execution: either promote the notebook kernel runtime to live status or invoke the Census query logic via scidex.tool.invoke once a CELLxGENE-Census tool is registered. Until notebook 8669f4b4 executes, dataset 729a2ac1 remains in deposition_status=draft and the cross-cohort composition analyses in research_plan 816f97a6 cannot proceed past hypothesis.",
