Linkable is a lightweight WordPress plugin that automates internal linking by converting defined keywords into links to selected posts or pages.
Core functionality: 
* Automatically links keywords to chosen posts or pages 
* Works on singular posts and pages by filtering <code>the_content</code> at priority 20 
* Searches for keyword matches inside <code></code>, <code><li></code>, <code></code>, <code></code>, and <code></code> tags 
* Skips self-links by excluding the current post from the keyword map 
* Uses the Yoast SEO title for link tooltips when Yoast is active, otherwise falls back to the WordPress title 
* Preserves existing <code><a></code> tags and shortcodes by backing them up before processing and restoring them afterward
Keyword management: 
* Keywords are stored per post and per page as JSON in the <code>linkable_tags</code> post meta field 
* <code>linkable_tags</code> is registered with REST support, sanitized via <code>sanitize_text_field</code>, and restricted to users with <code>edit_posts</code>
Settings: 
* Accessible via Settings → Linkable 
* <code>max_links_per_target</code>: limits how many times the same target can be linked from one post (default 1) 
* <code>first_occurrence_only</code>: when enabled, each keyword is linked only once per post
Performance: 
* Builds a global keyword map from all published posts and pages with <code>linkable_tags</code> 
* Caches the keyword map with a transient (<code>global_linkable_tag_map</code>) for one hour 
* Query optimized to fetch only IDs and avoid unnecessary meta/term caching
Editor compatibility: 
* Works with both the block editor and the classic editor 
* Enqueues an admin sidebar panel script (<code>static/js/admin-sidebar-panel.js</code>) with WordPress dependencies and versioning via <code>filemtime</code>
Security: 
* URLs are properly escaped with <code>esc_url</code> 
* Link titles are sanitized and HTML-escaped 
* Meta registration includes capability and sanitization checks
