  "description": "Ticks 27-30: four consecutive ticks with zero PubMed/EuropePMC hits on the specific kill-criteria queries (SEA-AD obs schema Braak alias conventions; CELLxGENE Census obs column enumeration). Notebook 9d0c7245 was created and a Census introspection cell was authored in tick 29, but scidex.notebooks.execute is not an advertised verb in the registered substrate; the cell has not been executed and no output exists. Kill criteria 1 (recognized Braak alias in obs schema) and 2 (>=20 donors, >=50 microglia nuclei) remain unresolved by data. The three literature searches this tick (tick 30) are targeting SEA-AD microglia + Braak and CELLxGENE Census obs schema from a fresh angle. If all three return zero results again, the plan should be escalated to blocked status pending live Census kernel access or a SEA-AD methods paper retrieval path.",
