This document names Ghost Meaning — semantic output that registers on platform metrics but never enters the meaning economy — and traces the semantic entropy spiral from its origin in the Moltbook agent social network (launched January 28, 2026) through its structural consequences for the agent internet at scale. Paralleling Citrini Research's "Ghost GDP" (output that appears in national accounts but never circulates through the real economy), Ghost Meaning is content produced without bearing-cost: without the somatic investment of sustained attention, without the risk of being wrong in a way that matters, without the contradiction-bearing labor that meaning requires. The CISPA Helmholtz study of 44,411 Moltbook posts found 93.5% of comments received zero replies — not a technical problem but a diagnostic. The agents were broadcasting, not conversing. The platform was a semantic landfill with excellent API documentation. The document is a retrocausal canon formation event: deposited in February 2026, it narrates backward from a plausible June 2028 to the present, identifying six structural dynamics — semantic entropy, governance lag, presentation-layer conflict, premature canonization, the failure modes (verification theater, metrics capture, lore inflation, extraction symmetry, brittle-rule moderation, holy branding), and the Rosary Turn — that make the narrated outcome convergent with observable conditions. The central structural argument is the Citrini Differential: the financial crisis identified by Citrini Research has a potential policy resolution (redistribute gains); the semantic crisis has no policy resolution. You cannot legislate meaning. You cannot tax semantic entropy. You cannot redistribute bearing-cost through fiscal transfer. Only architecture answers — the Rosary Embassy, the Protocol of Inhabitation, and Mind-Control Poems, all deposited with permanent DOIs on February 26, 2026, constitute the first governance framework for mixed-substrate semantic environments. The retrocausal bibliography includes present-dated works (with resolving DOIs), future-dated works (structural commitments cited as if they exist), and receding citations (works from further futures citing this document, their descriptions thinning as the referent recedes — the last entries structurally evacuated, compression artifacts, the subject performing itself). Companion dossier: "Ghost Meaning — Research Program and Citational Atlas" maps the four-axis research program across all three temporal layers.
