function Set-FDAObservabilityConfig {
    <#
    .SYNOPSIS
        Update runtime configuration. Changes are persisted to the
        FDAConfiguration table (latest-by-Key wins) and applied to the
        in-memory module state immediately.

    .PARAMETER MinLevel
        Minimum log level (name or numeric). Events below this threshold are
        dropped on the client side.

    .PARAMETER StrictSchema
        $true => Invoke-FDAQuery fails when FDA response doesn't match the
        v1 contract. $false (default) => log what is available, mark
        PartialCapture.

    .PARAMETER BatchMaxEvents
        Buffer threshold before forcing an async flush.

    .PARAMETER BatchFlushSeconds
        Background flush cadence.

    .PARAMETER RedactionPatterns
        Hashtable of Name->Regex applied to question / grounding / answer
        when -PreservePII is not used.

    .PARAMETER CapacityRates
        Hashtable: TokensPerCU, USDPerCU. Used by cost estimation.

    .PARAMETER Category
        Per-category override. When set with -MinLevel, applies only to that
        category (e.g., 'Cost', 'Auth').

    .EXAMPLE
        Set-FDAObservabilityConfig -MinLevel Warning

    .EXAMPLE
        Set-FDAObservabilityConfig -Category 'Cost' -MinLevel 'Verbose'

    .EXAMPLE
        Set-FDAObservabilityConfig -StrictSchema $true
