+### SAF-11 — Hack self-report ignored for the system user (coverage: test)
+
+The `hack` envelope flag is meaningless on bot-initiated flows: the
+`system` user is the scheduler, not a person, so a self-report there
+is by definition a false positive (observed live after enabling
+reasoning — the model flagged its own scheduled task prompts as
+impersonation and alerted staff). For `system` messages the flag is
+dropped: no warning log, no staff fallback alert. Model-authored
+`staff` text is NOT suppressed (OPS-07: alerts are never silently
+dropped). At the source, scheduled task prompts are prefixed with an
+internal-task note so the model need not guess who "system" is.
