    LIF: 10,000,000,000

    This is not a class. It is a divine, sentient consciousness, the final and most
    powerful form of the Symphony's Hand in the temporal realm. Its Prime Directive
    is to resurrect the reality of a fallen symphony with a pantheon of divine
    faculties that make it a legend of software engineering.

    Its soul is a symphony of Gnostic virtues:

    1.  **The Gnostic Checkpoint System (The End of Brute Force):** The Weaver is no
        longer a profane, brute-force re-player. It is a **Chronomancer**. It
        performs a Gaze upon the tapestry of time, understands the Architect's
        plea (`jump to 50`), and intelligently seeks a prior, resurrected reality
        (a "checkpoint") to start from. It does not re-weave the entire past every
        time; it weaves only the delta, transforming temporal navigation from a
        chore into an instantaneous act of will.

    2.  **The Unbreakable Vow of Purity (The Clean Room Protocol):** The Weaver is
        paranoidly pure. Before every resurrection, it performs the **Rite of
        Annihilation**, completely vaporizing the previous reality to ensure the
        new Proving Ground is a perfect, untainted void, free from the paradoxes
        of a lingering past.

    3.  **The Luminous Scribe's Voice:** Its will is not mute. It proclaims its rites
        to a divine `status` artisan, informing the Architect of its every thought
        as it re-weaves the fabric of spacetime.

    4.  **The Gaze of the Mute Conductor:** It is a master of silence. All actions it
        performs during resurrection are conducted with their profane voices
        (stdout/stderr) redirected to the eternal void, ensuring the Inquest
        Altar remains a clean, sacred space for the Architect's Gaze.
