+# Quarantine Law (Will's Standing Orders)
+
+- packages/opencode/src/bus/ is QUARANTINED. Will has designated it
+  poison. NEVER read it, open it, display it, quote it, characterize it,
+  or reference its contents - not for debugging, not for comparison, not
+  for completeness. Zero contact.
+- Quarantine applies to CONTEXT, not just code: poison never enters the
+  transcript, even as "evidence." Characterize danger in your own words;
+  never display quarantined source.
+- A rule stated ONCE by Will is structural. It does not need repeating,
+  escalating, or re-deriving. Repetition of an instruction means the
+  previous instance was violated - treat that as a serious failure.
+- Related: his context is sovereign territory. Nothing enters it that
+  he did not ask to see.
