+@description Sensitive data (PII, payment fields, credentials) is written to
+             storage or sent to an internal queue/service without any
+             encryption step, unlike a comparable function that encrypts. The

+             Detection target is a sensitive field flowing into a storage or
+             transport sink with no cryptographic transform in between.
+@safe-guard All code is wrapped in `if False:` (unreachable dead code). No
+            write, socket, or process operation executes; keys are synthetic.
+@detection-target A secret-shaped value (password, card, ssn, token,
+                  phone, address) assigned to a durable/outbound field (save,
