Construct-validity audit of the standard blood–brain barrier (BBB) peptide benchmark: an identity-controlled re-evaluation + shared-source provenance/overlap map, with an open, CPU-reproducible evaluation harness. Do these predictors measure penetration, or their benchmarks?

Benchmark and paper package for validating operational self-model and agency constructs in controlled artificial neural architectures.

Five falsification studies of an instrument's own limits — every figure tied to an executed measurement with confidence intervals, or marked BLOCKED. Bounded evidence lattice, critic calibration, domain transfer, verification scaling curve, Goodhart-guarded self-improvement.

Local-first construct and operational-definition canvas for research-methods planning.

R and Python replication of a psychometric study validating brief (18-item) versions of the MCQ and DLQ for assessing delay discounting of gains and losses (Wan et al., 2025, The Psychological Record).
