WP Performance Inspector 2.0.1

WP Performance Inspector 2.0.1

This patch makes the Private Plugin Impact Test trustworthy under noisy local or production conditions.

• Uses WordPress' saved server-side PHP duration instead of total loopback HTTP duration.
• Correlates every request and database row with a signed probe UUID.
• Verifies that the requested plugin exclusion reached WordPress before accepting a measurement.
• Computes impact from five paired A/B deltas instead of subtracting two independent medians.
• Reports the individual pair deltas, median absolute deviation, noise floor and repeatability verdict.
• Labels recent request samples as all plugins or without plugin/file.php.

On the CGM test site, WooCommerce produced a repeatable positive PHP cost while CGM Scheduled Revisions correctly returned no repeatable cost. The previous profiler could misleadingly assign similar whole-request timing swings to both plugins.
