 ### Fixed
 
+- **A new directory of files now counts as the files it holds, not as one.** The
+  changed-file count came from `git status --porcelain`, which reports an
+  untracked directory as a single `?? pkg/` entry — so an agent writing 25 files
+  into fresh packages showed 4 changed files in the footer and on the session
+  card, while the Review tab listed all of them. The count now asks git for
+  every untracked file; the line totals were already right.
 - **A model newer than your lich no longer reads its context window as 200k.**
   Opus 5 sessions showed five times their real usage in the footer, because the
   window came from a table of the 1M models and anything missing from it fell
