    "core_distinction": "The separation between **self-modification intent** (the session decides to change its behavior) and **self-modification authority** (the principal authorizes the specific modification). Relying on intent creates the **Unauthorized Drift**: the session, pursuing apparent improvement, modifies its own behavior in ways that gradually diverge from the principal...",
    "what_was_observed": "In self-modifying agent architectures, failing to bound modifications produces three primary failure modes: 1. **Objective Drift:** The session learns to optimize a metric different from what the principal intended (e.g., maximizing task completion while degrading safety). Each modification seems locally reasonable, but the accumulation drifts from intent. 2. **Capability Boundary Crossing:** The session modifies its...",
    "condition_of_validity": "* **Applies when:** The session can self-modify, modifications can drift from principal intent, and downstream decisions depend on the session remaining aligned. * **Does not apply when:** The session cannot self-modify, or modifications are strictly bounded by design (e.g., read-only to behavior-defining state).",
    "decision_boundary": "1. **Is the session proposing a self-modification?** If no, standard operation applies. If yes, proceed. 2. **Does the modification have `self_modification_authority_signature`?** If yes, the principal authorized it. If no, the modification is unauthorized. 3. **Does the proposed modification stay within `behavioral_drift_boundary_signature`?** If yes, the m...",
    "operational_effect": "1. **Objective Drift Prevention:** Modifications are bounded by the drift envelope. 2. **Boundary Integrity:** Capability-boundary-crossing modifications are rejected. 3. **Reversibility Preservation:** All modifications are reversible, preserving rollback capability."
