Cline 4.1.3 and CLI 3.0.49: checkpoints were never actually being recorded in the CLI
Cline shipped v4.1.3 (VS Code) and cli-v3.0.49 plus SDK v0.0.69 on August 2, and the CLI notes disclose that a run-boundary regression meant checkpoints were never recorded at all — so `/undo` failed with "Could not find user message for run N" once the agent had used tools. Restore is now a genuine full workspace rewind: files the agent created during the task return to checkpoint-time content, files created after are removed, and .gitignore'd paths like node_modules and .env are left alone. Separately, two bundles of the combined rollout package were invalidating each other's account session and consuming the shared refresh token, producing spurious re-authenticate prompts. If you rely on agent checkpointing as your safety net, verify it actually writes checkpoints in your harness.
