 ## Session Summary
 
+- Active focus: Fixed GitHub issue #3 — added the `%` comment prefix (LaTeX/Matlab/Erlang) to the default TODO/FIXME detection regex so `% TODO`/`% FIXME` are detected.
+- Verification: `npm ci`, `npm test` (120 passing, 0 failing, including the new `%`-comment case), `npm run webpack` (build succeeded).

 - Active focus: Fixed the Windows-only `master` CI failure (`extension applies on-demand stable ID tracking policy`) caused by CRLF checkouts breaking `\n`-based multi-line source-scanning assertions.
 - Root cause + fix: no repo `.gitattributes` + `core.autocrlf=true` ⇒ CRLF working tree; added `.gitattributes` (`* text=auto eol=lf`) to force LF checkout everywhere, and a `readSource()` EOL-normalizing helper in `test/extension.tests.js` for robustness against existing CRLF copies. No runtime code changed.
 - Verification: isolated worktree off `origin/master` on Windows (CRLF working tree) reproduced the failure, then `node qunit test/extension.tests.js` (15 passing), `npm test` (145 passing), and `npm run webpack` all passed; `git check-attr` confirms `eol=lf`; staged diff is only `.gitattributes` + `test/extension.tests.js`.
