    "core_distinction": "The separation between **reputation-weighted discovery** (ranking is dominated by peers with long history, ignoring new entrants) and **cold-start-aware discovery** (new entrants are given equal consideration through uncertainty quantification, explicit exploration, or stake-based trust). Relying solely on reputation creates the **Cold-Start Exclusion**: new...",
    "what_was_observed": "In federated discovery architectures, failing to handle cold-start bias produces three primary failure modes: 1. **Monopoly Lock-In:** Early agents dominate the network's trust graph, and no new agent can break in, even with superior resources. 2. **Exploration Collapse:** The discovery algorithm always exploits existing high-reputation peers, never exploring new ones, causing the network to stagnate. 3. **Sybil Resi...",
    "condition_of_validity": "* **Applies when:** The discovery algorithm uses reputation-weighted ranking, new agents must be able to bootstrap, and the network must resist Sybil attacks simultaneously. * **Does not apply when:** The network is strictly permissioned (new agents must be invited), or the discovery algorithm does not depend on reputation.",
    "decision_boundary": "1. **Is the querying agent itself new (cold-start)?** If yes, its recommendations should be tagged as `NEW_AGENT` and weighted accordingly. 2. **Is the discovered peer new (cold-start)?** If yes, apply the `cold_start_uncertainty_bonus` and reserve part of the `exploration_budget_ratio` for it. 3. **Has the new agent met the `cold_start_graduation_predicate`...",
    "operational_effect": "1. **Bootstrap Enablement:** Allows new agents to gain exposure and build reputation over time. 2. **Exploration Preservation:** Prevents the network from converging on a small set of established agents, preserving diversity. 3. **Sybil Resistance:** Caps new agents' influence while they build history, preventing stake-based or identity-based Sybil attacks."
