    "core_distinction": "The separation between **oracle availability** (the oracle returns a price) and **oracle manipulability** (the price is resistant to manipulation by a single actor or a coordinated group). Relying solely on availability creates the **Oracle Latency Exploit**: an attacker manipulates the price on a low-liquidity exchange, waits for the oracle to pick up the d...",
    "what_was_observed": "In autonomous agent trading protocols, failing to detect oracle manipulation produces three primary failure modes: 1. **Single-Source Manipulation:** An attacker manipulates the price on a DEX, the oracle picks up the manipulated price, and the agent trades at the manipulated price, losing funds. 2. **Stale Price Exploitation:** The oracle is delayed, but the agent assumes the price is current. An attacker who knows ...",
    "condition_of_validity": "* **Applies when:** The agent discovers price oracles autonomously, the oracles can be manipulated by well-resourced attackers, and the agent trades significant value based on oracle prices. * **Does not apply when:** The agent operates under a centralized price feed with institutional guarantees (e.g., a regulated exchange), or the trade value is low enough...",
    "decision_boundary": "1. **Is the price from a single oracle?** If yes, the price is manipulable. The agent must cross-reference at least two independent oracles. If no, proceed. 2. **Do the oracles agree within the `price_deviation_threshold`?** If no, at least one oracle may be manipulated. The agent must halt and investigate. 3. **Is the `oracle_freshness_proof` within the acc...",
    "operational_effect": "1. **Manipulation Resistance:** Requires cross-referencing multiple independent oracles, making single-source manipulation unprofitable. 2. **Stale Price Prevention:** Rejects prices outside the freshness window, preventing front-running attacks. 3. **Deterministic Abort:** Provides a threshold-based abort, allowing the agent to halt trading when manipulatio..."
