Node.js 20 actions are deprecated. The following actions are running on Node.js 20 and may not work as expected: actions/attest-build-provenance/predicate@36fa7d009e22618ca7cd599486979b8150596c74, actions/attest@67422f5511b7ff725f4dbd6fb9bd2cd925c65a8d, actions/checkout@692973e3d937129bcbf40652eb9f2f61becf3332, actions/setup-dotnet@67a3573c9a986a3f9c594539f4ab511d57bb3ce9. Actions will be forced to run with Node.js 24 by default starting June 16th, 2026. Node.js 20 will be removed from the runner on September 16th, 2026. Please check if updated versions of these actions are available that support Node.js 24. To opt into Node.js 24 now, set the FORCE_JAVASCRIPT_ACTIONS_TO_NODE24=true environment variable on the runner or in your workflow file. Once Node.js 24 becomes the default, you can temporarily opt out by setting ACTIONS_ALLOW_USE_UNSECURE_NODE_VERSION=true.

The behavior of 'StringBuilder.AppendLine(ref StringBuilder.AppendInterpolatedStringHandler)' could vary based on the current user's locale settings. Replace this call in 'SseServiceTests.ParseSseStreamAsync_ShouldRespectCancellationToken()' with a call to 'StringBuilder.AppendLine(IFormatProvider, ref StringBuilder.AppendInterpolatedStringHandler)'.

'string.Replace(string, string?)' has a method overload that takes a 'StringComparison' parameter. Replace this call in 'Arbor.HttpClient.Core.HttpRequest.CurlFormatter.ShellEscape(string)' with a call to 'string.Replace(string, string?, System.StringComparison)' for clarity of intent. (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1307)

'string.IndexOf(char)' has a method overload that takes a 'StringComparison' parameter. Replace this call in 'Arbor.HttpClient.Core.Variables.VariableResolver.Resolve(string, System.Collections.Generic.IReadOnlyList<Arbor.HttpClient.Core.Environments.EnvironmentVariable>)' with a call to 'string.IndexOf(char, System.StringComparison)' for clarity of intent.
