Struct Span 

pub struct Span(pub Range<usize>);

A half-open range of message indices: the primitive for pointing at part of a session. Owned and serializable, so it crosses process and wire boundaries (search results, CLI arguments, MCP responses); resolution against a loaded transcript is Transcript::fragment.

Indices are positions in the parsed snapshot the span was minted against. They stay valid as a live session appends; they are not stable across cross-harness conversion.
