Spans
Create a span note
Add a note annotation to a span. By default each call appends a new note with an auto-generated UUIDv4 identifier, so multiple notes accumulate on the same span. Callers may supply a non-empty identifier to upsert on (span_id, name=‘note’, identifier) — repeated calls with the same identifier overwrite the existing note, matching the semantics of structured annotations.
