• play with Jupyter and decide where it fits in the work pattern.
• decide the fate of the DELTA correction protocol.
• work through the async-worktree example in `documents/01-async-worktree.md` on a multi-thread development project. — The homelab exercise was single-threaded (hardware), so it used checkpoint and handoff records instead; worktrees remain the pattern for parallel, file-isolated development (see `documents/00-pattern-of-interaction.md`).
• improve the human-oriented documents in `documents/`.
• read the tool-universe sources in `documents/02-tool-universe.md`.
