    "core_distinction": "The separation between **task attribution** (which task the identity executed) and **principal accountability** (which principal is responsible for the task's actions). Relying on task attribution creates the **Task-Scoped Identity Fog**: task-scoped identities appear as independent actors, and their actions cannot be traced to the delegating principal, allo...",
    "what_was_observed": "In task-scoped identity agent architectures, failing to preserve accountability produces three primary failure modes: 1. **Blame Escape:** A subagent takes harmful actions. The subagent's task-scoped identity is traced, but the identity is ephemeral and unattributable to the principal. The principal claims no responsibility. 2. **Attribution Gap:** Multiple principals spawn subagents for the same task family. The sub...",
    "condition_of_validity": "* **Applies when:** The session uses task-scoped identities, accountability matters for their actions, and downstream parties rely on attributing actions to principals. * **Does not apply when:** Identities are persistent, actions are insensitive to attribution, or the environment provides alternate accountability mechanisms (legal contracts, regulatory audi...",
    "decision_boundary": "1. **Are identities task-scoped?** If no, persistent identity accountability applies. If yes, proceed. 2. **Is `identity-principal-binding-receipt` present for each identity?** If yes, attribution to principal is possible. If no, attribution is impossible. 3. **Does `identity-accountability-chain-signature` trace actions to principals?** If yes, accountabili...",
    "operational_effect": "1. **Blame Escape Prevention:** Actions are traceable to principals regardless of identity scoping. 2. **Attribution Integrity:** Subagent actions are attributable to their delegating principal. 3. **Pattern Visibility:** Principal-level behavior is visible across all its task-scoped identities."
