Pull request overview

Adds support for filtering App Configuration settings and feature flags by tag expressions (via tags-filter), and updates selector model JavaDocs intended to improve configuration metadata/YAML hinting.

Changes:

• Adds tagsFilter to key/value selector models and propagates it into SettingSelector when listing settings and feature flags.
• Updates loader/client/property source APIs to thread tags filter through the loading pipeline.
• Expands unit test coverage for tags filter behavior (null/empty/custom) and snapshot incompatibility.

• getLabelFilter(List<String> profiles) reverses the provided profiles list in-place. This can throw UnsupportedOperationException when profiles is immutable (e.g., Spring Boot may supply an unmodifiable list), and it also mutates caller state. Consider making a defensive copy (e.g., new ArrayList<>(profiles)) before reversing, similar to AppConfigurationKeyValueSelector.getLabelFilter’s approach.

    public String[] getLabelFilter(List<String> profiles) {
        if (labelFilter == null && profiles.size() > 0) {
            Collections.reverse(profiles);
            return profiles.toArray(new String[profiles.size()]);
        } else if (!StringUtils.hasText(labelFilter)) {

This test is asserting fluent API behavior, but assertEquals will pass as long as equals() considers the objects equal. Use assertSame(selector, returned) to ensure the method returns the exact same instance (this).

[Copilot]

To verify the fluent setter returns the same instance (this), prefer assertSame(selector, returned) instead of assertEquals(...). assertEquals can still pass if equals() is overridden in the future.
