v4.8.1 — Cwd-Robust uv Hooks

What's new

Turing's generated Claude Code hooks are now robust to Claude changing directories during a session. Scaffolded hook commands point at absolute script paths, so stop and post-train hooks keep finding the intended harness files instead of accidentally resolving paths relative to whatever cwd Claude happens to hold.

The generated harness is also uv-first end to end. Hook scripts run Python through uv run python, scaffold setup uses uv sync, and the user-facing instructions now teach the same execution contract the scripts enforce.

Cwd-robust hook commands

• Generated .claude/settings.local.json hook commands now use absolute script paths
• Stop hooks continue to preserve convergence exit code propagation
• Post-train hooks preserve fallback run.log handling when invoked from a different cwd

uv-first scaffold runtime

• Added a shared hook helper for uv run python
• Missing uv now fails loudly instead of silently falling back to ambient Python
• Scaffold setup, templates, agents, and command guidance consistently use uv sync and uv run

Numbers

• 2041 tests
• 74 commands
• 93 scaffold scripts
• 4 implementation commits since v4.8.0
