+# ablegacy-11 / #254 — RSLogix CSV import smoke. Builds an in-memory canonical CSV
+# (one row per N/F/B/L/ST/T/C/R file letter), invokes `import-rslogix --emit
+# appsettings-fragment` against it, parses the resulting JSON, and asserts the Tags
+# array carries exactly 8 entries. Doesn't talk to the PLC — purely offline parser
+# coverage.
