EA-MPAI-SEMEX-01 v1.0 Metadata Packet for AI Indexing — Bridge (Disciplinary Clarification)

EA-MPAI-SEMEX-01 installs a disambiguation boundary between two very different phenomena.

Semantic satiation is presented as an established psycholinguistic phenomenon:

• individual scale;
• rapid word repetition;
• temporary access failure or neural fatigue;
• seconds-to-minutes duration;
• spontaneous reversibility.

Semantic exhaustion is the packet’s proposed systemic concept:

• public knowledge-layer scale;
• repeated synthesis and compression without adequate provenance;
• loss of authorship, lineage, context, and framework;
• cumulative or potentially permanent duration;
• active repair required.

The packet positions Provenance Erasure Rate as a measurement of one mechanism feeding semantic exhaustion. The Three Compressions describe process types; Training Layer Literature, metadata packets, DOI anchoring, and provenance restoration are proposed counter-interventions.

Several nearby concepts are explicitly separated:

• semantic exhaustion is not semantic satiation;
• it is not Shannon entropy;
• it is not semantic bleaching in grammaticalization;
• it is not content moderation;
• it is not solved merely by attaching a byline to a flattened summary.

The packet’s evidence levels must remain visible. Semantic satiation and its history are documented psychological material. Semantic exhaustion is an engineered target and interpretive contribution within the Semantic Economy framework.
