5. Stand the conflict pass down when the load gate says no

[nikolaystrikhar]

What: Conflict\Detector::is_in_conflict() applies {prefix}/plugin_absorber/should_load, so the conflict pass at plugins_loaded priority 5 sees the gate the load pass reads at 6.

Usage:

add_filter( 'give/plugin_absorber/should_load', static function ( $load, $sub_plugin ) {
    return 'give-recurring' === $sub_plugin->get_slug() ? false : $load;
}, 10, 2 );
// The standalone is left active, and no merge notice claims it was replaced.

Why this way:

A veto used to cost the site the feature outright. Under the default policy the standalone was deactivated, the merge notice said the bundled copy had taken over, the request redirected — and priority 6 then required nothing. docs/filters.md steers hosts straight into it: a per-slug return false is its only worked example.

The filter goes last. It is host code, so the sub-plugin must be enabled, name a standalone, and have that standalone running before any of it executes — which is also where the load pass asks it, and it keeps the filter off every request that has no conflict.

No new catch. Boot\Scheduler wraps the step in catch ( Throwable ) and Conflict\Resolver catches per sub-plugin, so a filter that throws is already reported and already survivable.

Summary by CodeRabbit

• Bug Fixes

  • Bundled plugins blocked by the should_load filter no longer load or trigger conflict handling.
  • Standalone plugins remain active without notices or redirects when their bundled counterpart is vetoed.
  • Once the filter allows loading again, standard conflict resolution proceeds as expected.

• Documentation

  • Clarified filter timing, repeated evaluation, callback requirements, and standalone plugin configuration.
  • Documented that conflict detection is side-effect-free and respects the load gate.

📝 Walkthrough

Walkthrough

The conflict detector now checks the should_load filter before treating a bundled sub-plugin as conflicting. Documentation, unit tests, and an end-to-end scenario cover filter behavior, ordering, arguments, cleanup, and policy resolution.

Changes

Conflict load-gate handling

Layer / File(s)	Summary
Detector load-gate evaluation src/Conflict/Detector.php, docs/conflict-handling.md, docs/filters.md	Detector::is_in_conflict() applies should_load after existing eligibility checks. Documentation describes timing, repeated calls, and veto behavior.
Detector load-gate unit coverage tests/unit/Conflict/DetectorTest.php	Tests cover vetoes, callback arguments, return values, ordering, skipped checks, and callback cleanup.
Vetoed bundled-plugin scenario tests/unit/Scenario/ConflictTest.php	The scenario verifies that a vetoed bundled sub-plugin leaves its standalone active, then restores conflict resolution after the veto is removed.

Inline comments:
In `@docs/conflict-handling.md`:
- Around line 5-8: Rewrite the veto clause in the policy description so it is
grammatical and explicitly states that a vetoed bundled copy must not deactivate
the standalone, because no bundled copy will load.

In `@docs/filters.md`:
- Around line 40-42: Update the filter timing explanation to distinguish
callback priority from registration time: filters registered before the
plugins_loaded priority-5 conflict pass runs are considered, regardless of their
callback priority; only registration after that pass has executed is too late.
Preserve the existing guidance about using the enabled configuration key for
sub-plugins with standalone_plugin_basename.

In `@src/Conflict/Detector.php`:
- Around line 97-100: Update the comment above the enabled check to remove the
claim that preceding checks “cost nothing,” since Sub_Plugin::is_enabled() may
invoke configured code; describe only the evaluation order and gating behavior,
preserving the existing symbols and logic.

Code looks fine, but what CodeRabbit pointed out makes sense to fix up quickly.
