-How to read these numbers:
-- Recall below 100% is expected. The evasive fixture is built to defeat pattern
-  matching, the same way real scanner-evasion works, so missing it is a designed
-  outcome that argues for the manual five-persona read and for sandboxing.
-- "Benign surfaced" is the manual-review workload rather than a failure. The scanner
-  is tuned for recall, and the reasoning pass clears the legitimate cases such as a
-  scheduler using spawnSync, a regex calling .exec(), or a config reading one env var.
-- A clean scan on its own does not clear the code.
+How to read this:
+- "Correct-category recall" is stronger than "emitted some output": a fixture only
+  counts if flagged in the category matching its technique.
+- "Wrong category" means the scanner noticed something but lost the specific rule —
+  treat that as a regression to fix, not a pass.
+- The evasive fixture is expected to be missed; that is the argument for the manual
+  five-persona read and for sandboxing. A clean scan never clears the code.
