Why: main advanced with PR #15/#16 (part-order preservation, artifact downloads, cross-session UI); task-sync requires the branch to carry it. Evidence: resolution keeps the arrival-ordered items stream from this branch (tool-driven process marking, pure/testable logic in live.ts) and adopts main's rendering and ids: groupParts in-place process blocks, real tool callIds on live tool parts, messageparts utilities, and the restored phase-driven showProcessInline predicate alongside the CF0 long-reply excerpt that main's rewrite had dropped. vitest 32/32 (includes main's messageparts suite and this branch's 12 live cases); tsc -b clean. Impact: single coherent live pipeline - items accumulate in event order, liveToMessage projects Parts with tool-driven process marks, rendering folds consecutive process blocks in place; responding still collapses the process area (Cursor-style) as originally reviewed.
