Causal Loop Integrity for Observable-Only Backcasting: Strong No-Meta Supplement (Operational Core)

Causal Loop Integrity for Observable-Only Backcasting: Strong No-Meta Supplement (Operational Core)This paper specifies an operational core for Observable-Only Backcasting under No-Meta autonomy: agents coordinate and self-verify without relying on privileged judges, hidden ground truth, or subjective authority.It provides a deterministic, fail-closed framework for causal-loop integrity when “future-conditioned” constraints are used to gate present actions. The specification introduces: (i) wire profiles and a commit/open protocol with signed commitments; (ii) a proof-system registry and canonical hashing rules (including RFC 8785 JSON canonicalization and a Hashable Numeric Encoding) to prevent…
