    "body_text": "Mechanism-level audits ask how a system computes, not only what it emits. In four- and five-unit stochastic networks with known ground truth, the authors study when integrated information can be identified and certified from finite, noisy interventions. A recurrent and a feed-forward network produced identical delayed input-output behavior while carrying 0.28 and 0 bits respectively; internal recordings separated them in 4 to 53 trials. When units were omitted from one-step recordings, however, the resulting 0.30-to-1.02-bit precision floors persisted regardless of sample size. The measure also changed sharply near partition boundaries, although one-sided lower-bound certificates remained possible. These small synthetic systems do not establish machine consciousness; they show that measurability depends on experimental access and design, not behavioral fit alone.",
