 1. Prefer `stbbr_for_query(namespace, xml)` for IQ roster or disco queries where the namespace is stable.
 2. Use `stbbr_send(xml)` for presence, message, and other push style stanzas.
 3. Avoid `stbbr_for_id` unless the protocol flow genuinely requires correlating a specific request/response pair not covered by a namespace query.

 During the migration it's acceptable for a test file to mix old and new styles; opportunistically refactor brittle sections when touching a test for other reasons.
