A bigger model needs more than more cells
Biological constraints and proposed measurements. Cakir and colleagues reported cortical organoids engineered with a vascular-like system. This addresses a real limitation of three-dimensional neural models: supporting living tissue within a complex structure. Vascular-like organization is not automatically equivalent to the mature, regulated circulation of an intact brain. Claims about improved support must be tied to the structure and function actually measured.

Necromancer should track tissue viability and internal heterogeneity rather than use size as a stand-in for success. A proposed engineering comparison would ask whether different regions remain healthy, whether changes in recordings reflect biology or an unstable interface, and whether the model remains suitable for its intended question. None of those outcomes alone would validate a consciousness cloud.
Maturation, model consistency, interface stability, and interpretation are separate workstreams. Improving one measurement can worsen another. The proposed decision record should state the tradeoff, the evidence, and the next measurement needed. Druids own the model’s biological suitability; Artificers own interface performance; Wizards assess whether the result answers the question. Scaling follows characterization rather than a target mass of tissue.
Open this exact section in the Necromancer dossier. The original chapter status is “Biological constraints and proposed measurements.”
