// TestNoAnalyticsOrTelemetryDeps guards the module graph: Pingularity ships no
// analytics, telemetry, product-usage, or crash-reporting SDK (see
// docs/security-model.md), and one must not be pulled in - directly or
// transitively - without a deliberate, reviewed change to this denylist. It
// scans go.mod AND go.sum (the full build list), so a transitive pull is caught
// too. Each entry is a module-path fragment specific enough not to match an
// unrelated module.
