function Get-GraphDocumentation {
    <#
    .SYNOPSIS
        Document one Intune/Entra policy object and return the per-object result.

    .DESCRIPTION
        Public, UI-independent entry point for documenting a single PolicyObject.
        Returns the PSCustomObject the output providers consume — does not write
        any files itself. Use Start-GraphBulkDocumentation for a batch run that
        also drives output providers.

        Dispatch:
          1. Looks up a per-@odata.type custom handler in [DocumentationRegistry]
          2. If none claims the object, falls back to the schema-driven input-
             provider chain (Settings Catalog / ADMX / Intent / Compliance V2 /
             generic Profile)
          3. If no provider matches either, returns an empty result with
             InputType='NoProvider' rather than throwing

        Phase 2 wires the dispatch shape; handlers and input providers are
        populated in phases 4 and 3.

    .PARAMETER PolicyObject
        The IntunePolicyBase-derived object to document.

    .PARAMETER Language
        Language code for translatable strings. Defaults to 'en'.

    .PARAMETER Options
        Hashtable of engine-wide flags. Recognized keys:
          IncludeScripts          [bool] include embedded script bodies (default true)
          ExcludeScriptSignature  [bool] strip script signing blocks (default false)
          IncludePolicyId         [bool] include policy ID in basic info (default false)
          ExcludeAssignments      [bool] omit assignment rows (default false)
          PropertySeparator       [string] separator for property collections
          ObjectSeparator         [string] separator for object collections
          SkipNotConfigured       [bool] omit empty or unconfigured settings and basic properties
          SkipDefaultValues       [bool] omit default or unconfigured values
          SkipDisabled            [bool] omit disabled settings
          SetUnconfiguredValue    [bool] substitute declared unconfigured values
          SetDefaultValue         [bool] substitute declared defaults
          NotConfiguredText       [string] notConfigured | empty | asis
          ValueOutputProperty     [string] value | valueWithLabel for ADMX settings
          SkipDocumentInfo        [bool] omit the document-info header every output
                                  provider writes at the top of a Full document
                                  (Organization / Generated by / Generated date)
          SourceTenantUnavailable [bool] the source tenant of an export is unreachable:
                                  skip source-tenant-specific lookups (assignments,
                                  scope-tag/filter/app names, etc.). Generic Intune
                                  schema is still resolved from any connected tenant.
                                  (Legacy alias: OfflineDocumentation.)
          Outputs                 [hashtable] explicit per-provider output options

    .OUTPUTS
        PSCustomObject — see [DocumentationContext]::ToResult for the contract.
