Arrigoo Block control

What this plugin does

A WordPress plugin that adds a "CDP Segment control" panel to every Gutenberg block's inspector. Editors pick segments (from the Arrigoo CDP) that the block should be shown to or hidden from. All blocks still render server-side; a frontend script reads the visitor's segments from the Arrigoo CDP and either reveals or removes the marked blocks in the DOM.

Commands

• npm run build — Builds both JS entry points with @wordpress/scripts (webpack) and copies src/bundle.js to build/bundle.js. The copy step is required because bundle.js is a pre-built CDP SDK artifact, not a webpack entry — webpack would otherwise overwrite or skip it.
• npm start — wp-scripts start (watch mode for src/index.js and src/frontend-loader.js). Note: this does not copy bundle.js; run npm run build once to seed it.
• composer install — Installs the arrigoo/cdp-php-sdk dependency and sets up the PSR-4 autoloader for the Arrigoo\WpCdpBlockControl\ namespace. The plugin relies on a Composer autoloader being loaded by WordPress (see README.md — the deliciousbrains "WP in git" pattern).

No test suite or linter is configured.

Architecture

Two-stage rendering (the core trick)

1. Server: every block with selected segments is rendered with a data-segments="seg1 seg2 !seg3" attribute. A `block in` hides them all by default (EndUser.php:34-38).
2. Client: frontend-loader.js waits for the CDP bundle to emit ao_loaded, reads the visitor's segment list from window.argo.get('s') (falling back to the base64-encoded arrigoocdp sessionStorage entry), then either unhides each block (display: block) or removes it from the DOM.

The ! prefix means "hide from this segment". The literal segment unknown matches visitors the CDP has not recognized.

PHP side (src_php/, namespace Arrigoo\WpCdpBlockControl\)

Hooks are registered in index.php. Three classes, all static:

• BlockControl — registers the editor JS bundle (build/index.js) and injects window.arrigooCdpSegments via wp_add_inline_script. Adds a selectedSegments array attribute to every block via register_block_type_args, and writes data-segments onto the outermost tag of each block via render_block. Owns the CDP segment fetch (cached 5 min in the ARRIGOO_CDP option).
• EndUser — emits the frontend `
