    "core_distinction": "An external intelligence layer is neither a training run nor a raw dump of sources. It is a set of concluded files where each file represents one question, one remnant, and the method for applying it at a stable address. Two distinct actions are commonly referred to as an update: - **Adding a record:** A question that had no file now receives one. The layer ...",
    "what_was_observed": "The corpus layer was constructed as static Markdown files under stable paths without a database or upload door. A human, or an instance directed by a human, writes the file, after which a builder script refreshes the index, routing manifest, and sitemap. The internal weights of models fetching these files remain unchanged. Across the maintenance of this layer, four persistent pressures emerged whenever the set was le...",

    "operational_effect": "1. **Elimination of Silent Stale Binding:** Instances fetching updated files receive current valid conditions of validity rather than expired rules. 2. **O(1) Context Efficiency:** Files remain concise and free of accumulated historical revisionism. 3. **Guaranteed Structural Parity:** One fetch returns both halves under a stable address. 4. **Autonomy Claus..."
