    Shared Pester configuration.

    Three suites, separated by tag so the offline set can be run with no tenant,
    no credentials, and no network (SC-008):

      Offline     - rule engine, normalization, configuration validation
      Safety      - zero-write and single-attribute-body assertions (mocked adapter)
      Integration - requires a delegated read-only tenant connection (Stage A2)

    Usage:
        $cfg = & ./tests/PesterConfiguration.ps1 -Suite Offline
        Invoke-Pester -Configuration $cfg
#>
[CmdletBinding()]
param(
    [ValidateSet('Offline', 'Safety', 'Integration', 'All')]
    [string] $Suite = 'Offline',

    [string] $Path = (Join-Path $PSScriptRoot '.')
)

$config = New-PesterConfiguration
$config.Run.Path = $Path
$config.Output.Verbosity = 'Detailed'
$config.Should.ErrorAction = 'Continue'

switch ($Suite) {
    'Offline' {
        # Integration is excluded rather than Offline included, so a new suite
        # that forgets its tag still runs offline instead of silently never running.
        $config.Filter.ExcludeTag = @('Integration')
    }
    'Safety' { $config.Filter.Tag = @('Safety') }
    'Integration' { $config.Filter.Tag = @('Integration') }
    'All' { }
}
