HyperTaxonomy Plugin Architecture

For contributors and advanced integrators who need HyperTaxonomy’s internal reference: file structure, database schema, caching, hook execution, and search internals.

This reference is split into the following pages:

• File Structure & Loading — directory layout, loading sequence, block build pipeline, and the dependency map.
• Function & Hook Reference — function organization by module, hook registration, and hook execution order.
• Database Schema — term/post meta keys, options, native-table indexes, custom tables, and transient caching.
• Feature Implementation — feature-flag enforcement, container groups, redirects, term icons, hidden terms, and conflict detection.
• Search Internals — search query architecture, the search widget, performance architecture, native block group filter, AJAX endpoints, and security.
• Sort & Filter Rendering (DOM Structures) — PHP rendering functions, the emitted HTML/DOM trees, and JavaScript events for the sort order picker and filter options panel.
