Audits blocks and shortcodes on every site in a WordPress Multisite network. For each site it records the registered blocks and shortcodes, plus any blocks and shortcodes used in content that are no longer registered, and where each one is used.
Each site captures its own registry and scans its own content into two central tables on the main site. Network admins get a report under the LH Network Tools menu, site administrators get a per-site report under Tools, and the data can be queried network-wide via MCP abilities.
