src/ made nine _doing_it_wrong() calls and no do_action() at all. Core's _doing_it_wrong() fires doing_it_wrong_run and then emits nothing unless WP_DEBUG is on, so on a production site every failure this library detects -- a typo'd bundled_plugin_file, a sub-plugin that threw during require, a conflict that could not be resolved, a duplicate slug, a boot that came too late to wire -- happened in complete silence. A host debugging "the add-on isn't there" had nothing to pull on. One action, named through Config::get_hook_name() like the filters: error( string $message, ?Sub_Plugin ). _doing_it_wrong() stays exactly as it was; it is the developer channel, and taking it away would regress every WP_DEBUG site. Traits\Reports_Errors joins the two channels in one method, so the failure this library is likeliest to add next -- a new gate -- cannot report down only one of them. It never throws whatever a listener does: the error action fires from inside handlers whose entire purpose is that nothing escapes them, and a diagnostic that could white-screen plugins_loaded would be a worse bug than the silence it replaces. A listener that throws is reported with a plain _doing_it_wrong(), never a second announcement, so one that throws every time cannot recurse. The hook prefix is what names these hooks, which makes a bootstrap that never set one the single failure the error action cannot carry. Traits\Guards_Hook_Prefix reports it through the shared method anyway: the name is built inside a try, and the case is stated in one place rather than left as a bare _doing_it_wrong() at a call site somebody has to notice. Conflict\Resolver goes over with the rest. Its per-sub-plugin catch is the one report whose silence a site owner feels directly -- a standalone left running beside the bundled copy after the pass that was supposed to deal with it -- so leaving it on the developer channel alone would have left the channel blind to the half of the library a fatal depends on. docs/actions.md rather than a heading in docs/filters.md: the two answer opposite questions -- how do I change what the library does, against how do I find out what it did. Six of the seven source files here are that swap and carry no argument of their own, which is more than the PR size cap allowed. AGENTS.md names the exception in the same commit, rather than leaving the rule and the diff disagreeing.
📝 WalkthroughWalkthroughThe PR adds ChangesError reporting channel
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The new production error channel can still be interrupted by an existing callback that throws, which may suppress failure reporting and prevent later sub-plugins from loading. Merge should wait until those callbacks are safely contained. Sequence Diagram(s)sequenceDiagram

- Around line 52-82: Update report_error and both _doing_it_wrong call sites so
exceptions from doing_it_wrong_run listeners are caught without recursively
invoking _doing_it_wrong(); route them through a non-recursive helper that
safely contains Throwable and allows the error action or recovery path to
finish. Add coverage for the initial and listener-failure paths, asserting the
next sub-plugin still loads.

What: adds
{prefix}/plugin_absorber/error(string $message,?Sub_Plugin $sub_plugin), fired from the load pass, the conflict pass, the registry read, the boot sequence, bothAbsorbertrampolines and the hook-prefix guard.Usage:
Why this way:
Nine report sites, and not one reachable in production.
_doing_it_wrong()prints nothing withoutWP_DEBUG, so a typo inbundled_plugin_fileleaves a support engineer with a class that does not exist and an empty log._doing_it_wrong()stays, and the action joins it in one method.Traits\Reports_Errors::report_error()is both channels or neither, because the failure this library is likeliest to add next is a new gate — and a gate wired to one channel is invisible in exactly the way this exists to fix.Seven source files, taking the size cap's new exception. Six are the mechanical swap of one call for the other,
src/Traits/Reports_Errors.phpis the only file with a decision in it, andAGENTS.mdrecords the exception in the same commit.Summary by CodeRabbit
