From 7f9b87e48ba21043145e6ca162a9392f7f09270e Mon Sep 17 00:00:00 2001 From: Alex Collins Date: Sun, 11 Jan 2026 14:27:44 -0800 Subject: [PATCH] Add explanatory inclusion/exclusion logging Selectors.MatchesIncludes now returns (bool, string). Context logs human-readable reasons for including or skipping items.
