"""The peer-dm title fallback for a reset LOCAL Bot Chat honours the listing's own filters.

``GET /api/sessions?title=Bot+Chat`` lists a reset lineage as its latest, untitled segment, so a
fallback returns the titled root. It must not resurrect a deliberately archived Bot Chat into
``hermes peer dm`` routing, nor answer a ``source=`` query the row does not match."""
