  "technical_statement": "The ultraviolet boundary is assigned the dimensionless unit u_b=(kappa^2 Lambda)_boundary=1. The boundary value is not derived from the semiclassical action; the final result is exponentially sensitive to it, and its microscopic justification is a central open problem.",
  "public_statement": "The strict channel fixes the boundary unit at kappa^2 Lambda = 1.",
  "qualifier": "",
  "source_in_paper": "CC Paper I v1.0, Sec. 9 and Appendix D.5",
  "external_foundations": "",
  "limits_open_issues": "Alternative O(1) boundary definitions are quantitatively different models, not a statistical uncertainty within the strict channel.",
  "relations": "",
  "version_history": "v1.2; v1.3 (2026-08-01): source citation updated to the paired-cap revision.; v1.4 (2026-08-03): stated as an independent selected boundary; sensitivity and open-problem status made explicit",
