Retrieval tools now register a PHI-free sourceId per record/list and stream a
data-source part with the real clinician-facing title; the system prompt asks
the model to cite facts inline as [[src:id]]. The chat renders those markers as
numbered inline citation chips (PreviewCard hover) via a Streamdown link
override, with a Sources footer fallback when the model omits markers.
