 ## Unreleased

+### Features and breaking changes
 
 - Give writable Pi nodes built-in shell tools for dependency installation, builds,
   tests, and repair. Shell calls participate in cancellation and the workspace
   write barrier before checkpointing; prompts describe workspace boundaries and
   shared resources. Read-only nodes still have no shell, and parent extension/MCP

   semantics. Ignored dependencies, caches, and build outputs are no longer
   automatically archived or passed to successors; already tracked and deliberately

+- **Shell tools in writable Pi nodes.** Workers can install dependencies, build,
+  test, and repair in their assigned workspaces. Read-only nodes remain shell-free;
+  worktrees use host permissions and are not security sandboxes.
+- **Git-aware checkpoints.** Tracked changes and non-ignored new files are
+  checkpointed. Keep artifacts needed by successors in non-ignored or deliberately
+  tracked paths; ignored dependencies and build outputs are no longer preserved.
+- **Pi reminders between steps.** Completion and pause reminders arrive after
+  the current response and tool batch, before the next model step.
+- **Clearer errors and status.** Invalid graphs show actionable errors; focused
+  reads show the selected execution's output/error and current control state.
+  Full status exports retain snapshots and failed-worker usage.

+See the [changelog](CHANGELOG.md#030--2026-10-04) for all fixes and credits.
