[{"type":"thinking","thinking":"No Lean toolchain installed on this machine (lean/lake/elan not found). So we cannot compile any Lean skeletons here. Options:\n\n1. Install Lean (elan) — that's a system-level install; possible but heavy, and building zeta-23-lean requires downloading Mathlib cache (~GBs) and a long build. D-007 deferred the full lake rebuild.\n2. Write skeleton files without compiling (statements only, unchecked syntax) — risky: uncompiled Lean is likely to have syntax errors; honesty demands we mark them unchecked.\n3. Ask the user: installing elan + toolchain + Mathlib cache is a big step; per pacing rule and the \"ask before big environment changes\" principle, I should ask.\n\nLet me check what lean-toolchain says and the size implications. Also check the Zeta23 structure to see what a skeleton would import.","signature":""},{"type":"text","text":"No Lean toolchain on this machine (`lean`/`lake`/`elan` all absent).
