• The inline script is now added to 'agents-manager' handle, but if enqueue_script() fails to enqueue the script (e.g., when get_assets_json() returns null), the inline script will fail to attach to anything, potentially causing a silent failure. Consider checking whether the script was successfully enqueued before adding the inline script data.

		wp_add_inline_script(
			'agents-manager',
			'const agentsManagerData = ' . wp_json_encode(
				array(
					'agentProviders'       => $agent_providers,
					'useUnifiedExperience' => $use_unified_experience,
				),
				JSON_UNESCAPED_SLASHES | JSON_HEX_TAG | JSON_HEX_AMP
			) . ';',
			'before'

Setting up the local dev env. Unrelated to your PR, but to help with testing I think we'll want the should_use_unified_experience function to allow proxied or local dev sites. We might want to borrow this from is_dev_mode in Big Sky.

This looks good and seems to work well on WPCOM and WoA.

Just saw the test failures that seem related.
