* test(elisp): cover coverage-summary source-file scan and under-dir filteringCraig Jennings3 days1-0/+27
| | | | Adds direct tests for cj/coverage-summary--source-files (non-recursive, subdirectories out of scope) and --under-dir (report entries outside the source dir dropped, survivors re-keyed relative to project root). Both were previously exercised only indirectly through the missing-file tests.
* fix(elisp): exclude generated package files from coverage source scanCraig Jennings3 days1-0/+18
| | | | | | cj/coverage-summary--source-files scanned SOURCE-DIR for *.el and treated every match as testable source. Build tools write NAME-autoloads.el and NAME-pkg.el into that dir, and undercover never instruments them, so the missing-file detection counted each as untested at 0% and dragged the file-weighted project number down. emacs-wttrin read 72.9% instead of 97.2% after eask wrote its autoloads file during a coverage run. seq-remove the generated files before returning. A genuinely untested source is still flagged. The new test asserts both.
* feat(elisp): add coverage-summary to the Elisp bundle with missing-file ↵Craig Jennings2026-05-311-0/+173
detection A line-weighted coverage total has a blind spot: a module no test loads never shows up in the SimpleCov report, so it can't drag the number down. The suite looks healthier than it is. This adds a summary that counts every source file on disk against the report and treats an absent file as 0%, weighting the project number by file instead of by line so untested modules stay visible. The script ships at languages/elisp/claude/scripts/coverage-summary.el, self-contained on stock Emacs (just the built-in json). It parses the undercover SimpleCov shape directly rather than depending on the editor's coverage engine, so it runs anywhere the bundle lands. I proved it against a real 103-file report: 93 tracked, 27 untested modules surfaced, project number 66.4%. Delivery follows the bundle convention. The script lives under the gitignored .claude/ footprint and gets auto-fixed on drift by sync-language-bundle.sh, which I made generic for any claude/scripts/* rather than coverage-specific. The Makefile targets ship as a project-owned fragment (languages/elisp/coverage-makefile.txt) that install-lang.sh seeds at the project root and sync drops into .ai/inbox/ when that convention exists. The bundle never edits the project's own Makefile. Tests: 12 ERT for the kernel (Normal/Boundary/Error per function), wired into make test via a new languages/*/tests/ discovery path, plus bats for the sync auto-fix and the inbox-drop guards. This is the Elisp pilot. The pattern is proven, so fanning out to Python, Go, and TypeScript is now a follow-up. Each one needs only its own parser and fragment. The plumbing is already generic.
