+
+**Status:** Draft \| **Updated:** 2026-02-17
+
+## Invariant
+
+A router MUST NOT emit user-visible output unless it delegated to a
+child session and returns child output (verbatim or bounded wrapper).
+
+## Enforcement
+
+Use capability gating + `emit_guarded` (RFC-0010) validated against the
+Event Ledger (RFC-0009).
+
+## Output rules
+
+Router may prepend exactly one bounded line:
+`Delegating to <agent> because <reason>.` Max 240 chars.
