    interpretation time by ~90% and saving 100+ hours per regulatory update.

    answers with citations instead of raw matches.
    * Orchestrated end-to-end pipelines spanning document parsing, action-item
    generation, evidence review, and risk analysis.

    chores, PR review and translations.
    * 2026 term: translation automation and the review workflow around it.
    * 2025 term: extended BIP-85 support, so child seeds load directly
    on-device.
