ATTR_SPEECH_ID: "lk.speech_id" = 'lk.speech_id'

Span attribute and event name constants for LiveKit Agents telemetry.

Attributes carrying conversational content, tool payloads, or other user data must include a dot-delimited pii segment (lk.pii.<name>). PII-enabled projects have these attributes stripped at the LiveKit Cloud collector, and the segment is the marker it honors. Such content must not be embedded in span names, event names, or log message bodies because those are not redactable. For structured attributes, the collector applies the marker recursively to keys in nested OTLP key-value lists and arrays.
