 Both serve as worked examples of the spec; neither is mandatory.
 
+### Alternate runtimes
+
+Adopters who want a richer agent layer than a focused Matrix bot can
+satisfy this spec on top of a general-purpose agent runtime such as
+[ZeroClaw](https://github.com/zeroclaw-labs/zeroclaw) (Rust, Apache-2.0
+/ MIT, ships Matrix + Nostr channels and Ollama provider out of the
+box). The spec is runtime-agnostic — what matters is that captured
+input produces conformant events per §4 and respects the community
+scoping in §5. A ZeroClaw-based implementation would carry the
+`["client", "zeroclaw", "<version>"]` tag (per §4.1) instead of
+`["client", "maubot-tracker", "..."]`; renderers ignore the difference
+since they filter by community `a`-tag.
