+# nash operator policy (docs/NASH.md §4.3) — baked into the narOS image.
+#
+# nash reads its levers ONLY from this file. They used to live in the environment
+# (NUCLEIC_NASH_DISABLE, NUCLEIC_REAL_BASH), which meant the process nash exists to
+# observe could turn that observation off in one word, silently. This file is root-owned
+# and not group/other-writable; nash checks that ownership before honoring a single line,
+# so an agent-created copy is ignored.
+#
+# Nucleic rewrites this file when it starts a container, carrying the `legacyShell`
+# rollback lever into `disable`. Editing it by hand is an operator action.
+
+# Observation may not be switched off by the observed process: a shell whose transport
+# env has been stripped, or which was handed NUCLEIC_SHELL_CAPTURE=off, still records and
+# spools to /var/spool/nucleic-nash for the drain.
