Summary
Pi's get_entries and get_tree RPC PR exposes append-order session entries and session tree reads. The change is a practical step toward custom UIs and headless integrations built on top of Pi's coding-agent runtime.
What changed
Pi opened read-only RPC endpoints for session entries and session-tree introspection.
Why it matters
Agent observability increasingly requires structured session access, not just terminal transcripts. Read-only RPC lets external tools build dashboards, replay views, or diagnostics without taking over execution authority.
Evidence excerpt
Agents Radar describes PR #6078 as adding get_entries and get_tree read-only RPC commands for append-order cursors and session trees.
