Confirm Startup.AutoApiLogonOperators is encapsulated behind a public read-only property

[Copilot]

Codacy flagged Startup.AutoApiLogonOperators as a public field that should be made private and exposed via a public property. The current branch already reflects that remediation: the mutable collection is kept private and consumers read it through a public read-only accessor.

• Encapsulation

  • Startup stores operator IDs in a private static list instead of a public field.
  • External callers access the values via AutoApiLogonOperators, exposed as IReadOnlyCollection<string>.

• Mutation boundary

  • Writes remain internal to Startup through AddAutoApiLogonOperator.
  • ConfigureContainer clears and repopulates the backing collection during bootstrap, preserving existing startup behavior while preventing external mutation.

• Representative shape

  private static readonly List<String> AutoApiLogonOperatorsInternal = new List<String>();
  
  public static IReadOnlyCollection<String> AutoApiLogonOperators =>
      AutoApiLogonOperatorsInternal.AsReadOnly();

• Behavioral coverage

  • Existing bootstrapper coverage already exercises the populated operator set and duplicate prevention through the public property surface.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• f.feedz.io
  • Triggering command: /usr/bin/dotnet dotnet test /home/REDACTED/work/TransactionProcessor/TransactionProcessor/TransactionProcessor.Tests/TransactionProcessor.Tests.csproj --filter VerifyBootstrapperIsValid --no-restore -nologo (dns block)
  • Triggering command: /usr/bin/dotnet dotnet test /home/REDACTED/work/TransactionProcessor/TransactionProcessor/TransactionProcessor.Tests/TransactionProcessor.Tests.csproj --filter ConfigureContainer_PopulatesAutoApiLogonOperators_WithoutDuplicates --no-restore -nologo (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
