The query waits. It will not change. It will not bend. This is the essence of immutability at the query level—an assurance that once approved, the logic, structure, and intent remain locked, untouched by later edits or silent manipulations.
Immutability Query-Level Approval is more than a safeguard. It is a contract between the data system and the decision that grants it passage. Once a query receives approval, both its text and parameters are fixed. No silent rewrites. No after-the-fact injections. The approved query becomes a frozen snapshot in time.
This approach eliminates a class of risks that slip past traditional review processes. In mutable systems, even after sign-off, someone can tweak a query or adjust a clause without triggering new approval. That weakens trust. With immutability enforced, trust is maintained because the query you executed is exactly the one you approved.
The implementation begins by binding the approval to a hash of the query and any bound parameters. Every execution request must match that hash. Any deviation triggers rejection, forcing a fresh review. It is simple—no complex reconciliation, no ambiguity about intent.
