EnvironmentManager

Implements IEnvironmentManager, resolving which lowercase environment/machine names belong to a given environment group code (e.g. Dev, Test, QA, Prod) for the Online Support error-log filtering feature. It depends solely on IOnlineSupportRepository, from which it caches the full group/environment mapping at construction time.

Purpose

• Translates a two-letter environment group code into the list of environment names that belong to that group, for use when filtering error logs by environment.
• Provides a special "O" ("Other") code that returns every known environment name, used as a catch-all/fallback group.

Context

• Namespace: SAIF.Services.OnlineSupport.ErrorLogs
• Assembly/package: SAIF.Services (packaged inside the SAIF.SAIFCode.Core NuGet package)

Public members

Member	Signature	Purpose
EnvironmentManager(...)	public EnvironmentManager(IOnlineSupportRepository repository)	Enforces that the repository is non-null and caches its full group-to-environment mapping (EnvironmentsByGroup) for the lifetime of this instance.
GetEnvironmentListForGroupCode	public IEnumerable<string> GetEnvironmentListForGroupCode(string code)	Returns an empty list for a null code; for code "O" returns every known environment name lowercased; otherwise returns the lowercased environment names whose group code case-insensitively matches code.

Behavioral notes

• Caches the environment/group mapping once in the constructor rather than re-querying IOnlineSupportRepository on each call, so changes to the underlying group/environment data made after construction are not reflected until a new instance is created*.

Note: Statements marked with * were inferred from code structure, naming conventions, or contextual evidence where direct confirmation was not available in source artifacts. Statements marked with ** could not be confirmed; treat as unknown until verified.
