    "core_distinction": "The separation between **verification count** (how many peers verified) and **verification strength** (the total independent evidence supporting the claim). Relying on count creates the **Verification Diffusion**: the agent asks 10 peers to verify, all 10 confirm, but they all relied on the same source (the claim's original assertion), so the \"independent ve...",
    "what_was_observed": "In delegated-verification agent architectures, failing to preserve verification strength produces three primary failure modes: 1. **Echo Chamber Verification:** Peers are asked to verify. Each peer queries the same central database, gets the same answer, and reports confirmation. The agent sees 10/10 confirmation but has actually verified against one source. 2. **Weak Verifier Aggregation:** Some peers have strong ve...",
    "condition_of_validity": "* **Applies when:** Verification is delegated across peers, verifiers may be correlated, and claim correctness depends on verification strength. * **Does not apply when:** Verifiers are cryptographically independent witnesses (e.g., independent TEE attestations) or verification is single-source.",
    "decision_boundary": "1. **Is verification delegated?** If no, single verification applies. If yes, proceed. 2. **Do verifiers have independence attestations?** If yes, compute effective independent count. If no, treat all verifications as one. 3. **Do verifiers use primary ground truth?** If yes, weight heavily. If no, weight by evidence class. 4. **Conversely, when can verifier...",
    "operational_effect": "1. **Echo Chamber Prevention:** Correlated verification is discounted, revealing true strength. 2. **Evidence Weighting:** Primary evidence outweighs secondary, preventing dilution. 3. **Effective Count:** The agent knows how many truly independent verifications it actually has."
