+## Protocol policy
+
+There is only one wire version — the current one. No legacy peers, no compatibility shims, no fallback paths for older builds. Anyone who wants to interop must run the current build; everyone else is out. Do not add backward-compat code, `#[serde(other)]` escape hatches, or "what if an old peer sends X" defenses.
