Walkthrough

The Insights summary now reports condition usage counts. The dashboard renders a conditions chart with pie and bar views. The selected view persists through the REST preferences API.

Changes

Condition Usage Insights

Layer / File(s)	Summary
Condition usage summary contract src/js/types/Insights.ts, src/php/Admin/Menus/Insights/Insights_Summary.php, tests/unit/Admin/Menus/Insights/Insights_Summary_Test.php	The summary exposes counts for snippets with and without conditions. PHP tests verify empty and grouped summaries.
Condition chart preferences src/php/REST_API/Preferences/Insights_View_Rest_Controller.php, tests/unit/REST_API/Preferences/Insights_View_Rest_Controller_Test.php	The REST API accepts the conditions chart key and defaults it to pie. Preference tests cover persistence and normalization.
Condition usage dashboard chart src/js/components/InsightsMenu/InsightsDashboard.tsx, tests/e2e/code-snippets-insights.spec.ts	The dashboard renders condition counts with configurable colors and views. E2E tests cover ordering, chart data, persistence, and rollback after a save failure.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: 🟡 Moderate · up to b47b6

The new condition chart can cause existing version 1 preference submissions without the new field to be rejected, preventing saved chart-view changes for affected clients. Resolve the backward-compatible defaulting or version the request contract before merge; tighten the chart assertion to preserve coverage of displayed counts.

Full details: Correctness And Security

Explanation

The PR adds conditionCounts to the localized Insights payload at src/php/Admin/Menus/Insights/Insights_Summary.php:128, but it does not update tests/unit/Admin/Menus/Insights/Insights_Menu_Test.php:44-47. When the test saves one snippet and calls enqueue_assets(), the actual keys are active, inactive, typeCounts, conditionCounts, locationCounts, and tagCounts. The test expects the old five-key list, so the unit test fails.

- Around line 213-214: Update the translation calls in the insights summary
mapping for the ‘with’ and ‘without’ labels to use fully qualified WordPress
translation functions by prefixing both __() calls with a leading backslash.

In `@src/php/REST_API/Preferences/Insights_View_Rest_Controller.php`:
- Line 35: The version 1 request validation must continue accepting chart
payloads containing only type, activation, and location. Update CHART_KEYS and
the associated validation/defaulting flow in Insights_View_Rest_Controller so
missing conditions is populated from DEFAULT_VIEWS['conditions'] rather than
rejected, and add a regression test covering the legacy payload.

In `@tests/e2e/code-snippets-insights.spec.ts`:
- Around line 106-107: Update the assertions around the conditions chart legend
to target each individual legend row, then verify the exact expected
label-and-count text for that row. Do not assert counts against the entire
.insights-pie-chart-legend container; ensure swapped counts and substrings such
as “10” cannot satisfy the expectations.
