The durable session log and the live client trace are two projections of ONE canonical artifact — the SDK session-entry log: the agent emits committed entries, the Server persists them AND projects the block-level trace from the same store. MVP runs two agent→server streams (durable settled-entry log + ephemeral, non-persisted live per-token trace — token streaming is mandatory); collapsing them into one token stream carrying log metadata is the post-MVP follow-up RIG-1580
