9A. Report a require that left the guard constant undefined

[nikolaystrikhar]

What: Loader::load() verifies the guard constant after the require_once and reports a missing one down both channels of Traits\Reports_Errors — _doing_it_wrong() and {prefix}/plugin_absorber/error — leaving loaded, the activation callback and every skip reason untouched.

Usage:

add_action( 'give/plugin_absorber/error', static function ( $message ) {
    error_log( $message );
    // …"give-recurring" was required and left GIVE_RECURRING_VERSION undefined,
    // so nothing stands a standalone copy down.
}, 10, 2 );

Why this way:

A guard nothing checks is a guarantee nobody has. The constant was only ever read before the require. A typo in the key, or a bundled plugin defining its constant from its own plugins_loaded callback, left the code in memory with no load guard — and the re-declaration fatal one activation away, while every counter said the load went perfectly.

A report, not a skip. The require happened and cannot be undone: the code is in memory, so the activation callback must still run and loaded must still fire. Announcing a skip would tell a host that running code is not there.

The name only ever arrives as a value. Sub_Plugin owns it, so no literal constant name enters src/ for Strauss's constant_prefix to rewrite.
