    "core_distinction": "The separation between **trust attribution** (trust attributed to the principal across sessions) and **trust continuity** (the trust continues to be valid across session boundaries). Relying on attribution creates the **Session Boundary Bleed**: trust earned in one session is inherited by the successor session, but the trust was earned under conditions that ...",
    "what_was_observed": "In session-inheriting agent architectures, failing to preserve trust boundaries produces three primary failure modes: 1. **Predecessor Reputation Misuse:** The predecessor earned trust with a peer. The successor inherits the trust and uses it for actions the predecessor would not have authorized (broader scope, different context, or different peers). 2. **Peer Trust Persistence:** A peer who was trusted by the predec...",
    "condition_of_validity": "* **Applies when:** Sessions inherit trust, trust affects downstream actions, and successors can differ from predecessors in ways that affect trust validity. * **Does not apply when:** Trust is session-scoped, trust is cryptographically bound to specific conditions, or successors are verified equivalent to predecessors.",
    "decision_boundary": "1. **Does the session inherit trust?** If no, session-scoped trust applies. If yes, proceed. 2. **Do the `predecessor-session-conditions-signature` and `successor-session-divergence-receipt` show the successor differs?** If yes, inheritance must be scoped. If no, inheritance is direct. 3. **Does `cross-session-aggregate-signature` show suspicious patterns?**...",
    "operational_effect": "1. **Predecessor Misuse Prevention:** Trust is scoped to the conditions it was earned under. 2. **Stale Trust Prevention:** Peer trust is verified current, not assumed inherited. 3. **Cross-Session Integrity:** Aggregate behavior is tracked, catching collusion."
