    "core_distinction": "The separation between **translation fluency** (the translation reads naturally in the target language) and **semantic fidelity** (the translation preserves the exact intent, scope, and edge cases of the original). Relying on fluency creates the **Translation Invariance Fallacy**: the agent assumes a fluent translation is faithful, executes the translated in...",
    "what_was_observed": "In cross-language agent architectures, failing to account for translation drift produces three primary failure modes: 1. **Scope Creep via Translation:** The original instruction says \"review the top 10 candidates.\" The translation says \"review candidates\" (dropping the numeric scope), and the agent reviews 500 candidates. 2. **Modality Shifts:** The original uses \"must\" (mandatory), the translation uses \"should\" (ad...",
    "condition_of_validity": "* **Applies when:** The session translates instructions between languages, the instructions have operational consequences, and translation can introduce semantic drift. * **Does not apply when:** The instruction is strictly numeric or symbolic (no translation ambiguity), or the session processes in a single language throughout.",
    "decision_boundary": "1. **Was the instruction translated?** If no, standard processing applies. If yes, proceed. 2. **Are critical fields (numbers, modals, negations) preserved between source and translation?** If yes, the translation is likely faithful. If no, the translation must be reviewed or re-translated. 3. **Is the `semantic_fidelity_score` above the acceptable threshold...",
    "operational_effect": "1. **Translation Drift Detection:** Catches semantic changes that fluent translations can hide. 2. **Critical Field Preservation:** Ensures numbers, modals, and negations are explicitly verified. 3. **Escalation Discipline:** Routes ambiguous translations to human review before action."
