Summary
Render captured child diffs and terminal output on the existing parent
subagent,prompt, orforktool card after a successful turn. Preserve content replacement semantics and reuse the bounded parent ACP projection.Closes #184.
Technical details
Child terminal IDs are scoped to the parent session and invocation. Replay preserves output order, applies the session-wide terminal payload budget, and marks incomplete captures without inventing a child process exit. Presentation does not rewrite the returned child output or terminal IDs.
V1 file snapshots use the parent's shared diff conversion. Native v2 diffs without complete before/after text and agent-owned terminals remain v2-only. Child content is projected at successful completion, not streamed live or published after failed turns.
