        The sacred, immutable map that links a lead's spiritual intent to the
        physical location of its answer in the Akashic Record. This is the
        "Cheat Code" that allows the Monolith to achieve 90% cost reduction.

        ### THE PANTHEON OF 12 LEGENDARY ASCENSIONS:
        1.  **The Isomorphic Vow (THE CURE):** Every key in this grimoire is a
            1:1 mirror of the `shard_key` in the `business_intelligence` table.
        2.  **O(1) Gnostic Scrying:** Utilizes a hash map for instantaneous,
            zero-latency intent resolution.
        3.  **Symbolic Purity:** Operates on the pure `AdjudicationIntent` enum,
            annihilating the "Magic String" heresy.
        4.  **NoneType Sarcophagus:** Employs `.get()` to gracefully handle
            unmapped intents, ensuring the Neural Bridge never fractures.
        5.  **Hierarchical Logic:** Maps broad intents (FINANCIAL) to the most
            critical shard (`minimum_ticket`), allowing for high-velocity triage.
        6.  **Achronal Trace Suture:** (Implicit) The calling function binds this
            lookup to the global X-Nov-Trace ID for forensic auditing.
        7.  **Extensibility by Design:** New intents can be sutured to new shards
            by adding a single line of law to the codex.
        8.  **Metabolic Efficiency:** Zero external dependencies. Pure Pythonic law.
        9.  **Bicameral Resonance:** Serves as the one true bridge between the
            Symbolic Engine's verdict and the Akashic Record's memory.
        10. **Socratic Fallback:** If an intent is unmapped, it returns None,
            signaling the Bridge to proceed to the Neural Cortex by default.
        11. **Semantic Clarity:** The structure makes the system's "First Thought"
            for any given intent transparent and auditable.
        12. **The Finality Vow:** A mathematical guarantee of either a valid
            shard key or a conscious decision to escalate to neural thought.
