Replay saved subagent history

Turns a snapshot from $export_subagents() back into ellmer turns for display, for example in subagent_chat_server(). Replaying never runs tools, calls a model or restores a chat. Access is checked again with disclosure; the IDs and scope stored in history grant nothing.

Usage

delegation_history(history, requester, disclosure, scope)

Arguments

history

A snapshot from $export_subagents().

requester

Who is asking, passed to disclosure. Authenticate it first.

disclosure

A DelegationDisclosure for this request.

scope

The scope the history belongs to, from your own records rather than from history. It must match the saved scope exactly.

Value

A list with one redacted view per subagent, each with ellmer turns. Artifact references are marked availability = "unresolved", since the saved status may be stale.
