+name: modkit_extract_calls
+description: |
+  Produce a per-read per-position table of base modification **calls**
+  (pass/fail/filtered, with the called base) from a modBAM using the same
+  thresholding algorithm as `modkit pileup`. Complementary to `modkit
+  extract full`, which emits raw probabilities: `extract calls` emits the
+  thresholded categorical decision per site per read.
