The EmbedBuildDate target uses DateTime.UtcNow which makes every build produce a different assembly, conflicting with the Deterministic build setting on line 26. This will break deterministic builds and may cause issues with build caching, reproducible builds, and package signing.

Consider using a source control-based approach (like git commit timestamp) or an environment variable that can be set to a fixed value in CI/CD pipelines while allowing dynamic values for local development builds. For example, you could check for an environment variable first: BuildDateUtc>$([System.Environment]::GetEnvironmentVariable('BUILD_DATE_UTC', 'EnvironmentVariableTarget.Process'))</BuildDateUtc> and only fall back to UtcNow if not set, or use SOURCE_DATE_EPOCH for reproducible builds.

The tests don't cover the edge case where a perpetual license is used but the build date is unavailable (null). According to the validation logic on line 37 of LicenseValidator.cs, if _buildDate is null, the perpetual license feature won't activate and the expired license will be rejected.

Add a test case that validates an expired perpetual license when no build date is provided (call new LicenseValidator(factory) without passing a buildDate, and ensure BuildInfo.BuildDate returns null in the test context). This should verify that the system gracefully handles this scenario and logs an appropriate error.
