 ## Data rules
 
-- `data/yearend_hot100_2016_2025.csv` is the only hand-placed
-  raw file; everything else in `data/` is script-derived.
-- Full lyrics are copyrighted: they stay in `data/lyrics/`
+- `data/source/` holds the immutable hand-placed raw files;
+  `data/captures/` is written only by the fetch commands and the
+  private import script; `data/manual/` is written only by the
+  user's own hand.
+- Full lyrics are copyrighted: they stay in `data/captures/lyrics/`
   (gitignored) and must never be committed or reproduced in
   full anywhere in the repo.
