+Fixed 2026-06-22: simplecov keys are absolute, git-diff keys repo-relative, so the exact-key intersect never matched. Added =cj/--coverage-relativize-keys= and normalize both tables to repo-relative in =cj/--coverage-read-and-display= before the intersect; intersect unchanged. New =test-coverage-core--relativize-keys.el= (5 unit + 1 integration through the real parsers). Full suite green.
 =modules/coverage-core.el:252= — =cj/--coverage-intersect= joins covered×changed by exact string key, but simplecov.json keys are ABSOLUTE paths while the git-diff parser returns repo-RELATIVE ones — zero matches ever, so working-tree/staged/branch scopes report ":tracked nil" for everything and F7's main feature is inert (whole-project scope works, same-source keys). Unit tests hand-build matching keys so they pass; add one integration test feeding a real undercover report + real diff. Normalize both sides to repo-relative. From the 2026-06 config audit.
