+# lean-llm-starter
+
+A deterministic Lean 4 verification harness that treats the LLM as an untrusted proposal engine and Lean 4 as the trusted kernel.
+
+## Architecture
+
+```text
+operator intent
+  -> Prolog gate
+  -> Granite 4.1 / Llemma inference
+  -> schema validation
+  -> Lean 4 parse / verify
+  -> WORM-ready audit artifacts
+```
+
+Trust split:
+
+- `inference/` proposes proof artifacts
+- `logic/` blocks unauthorized or malformed runs
+- `lean4/` type-checks and verifies
+- `infra/verification-loop/` pins deterministic execution
+- `eval/` runs reproducible local benchmarks

+## What This Starter Includes
+
+- Lean 4 harness skeleton
+- Granite 4.1 JSON interchange schema
+- Lean-side parser scaffold
+- Prolog gate and retry loop scaffold
+- vLLM / docker compose verification loop
+- MiniF2F-style eval harness
+- GitHub Actions CI scaffold
+- Hugging Face publishing docs and model card template
+- sample JSONL parse fixture
+
+## What It Does Not Pretend Yet
+
+- not fully air-gapped out of the box
+- not fully air-gapped out of the box
+- not a finished proof search system
+- not yet shipping weights
+
+Current verified state:
+
+- Lean 4 project builds successfully on this machine with `C:\Users\jessi\.elan\bin\lake.exe`
+- Python eval and inference files compile
+- parse-mode fixture is present
+
+This is a scaffold you can harden into:
+
+- a GitHub repo
+- a Hugging Face model or Space companion repo
+- a deterministic local verification loop
+
+## Quick Start
+
+If `lake` is not on your PATH on Windows, use:
+
+```powershell
+C:\Users\jessi\.elan\bin\lake.exe
+```
+
+### 1. Lean side
+
+```bash
+cd lean4
+C:\Users\jessi\.elan\bin\lake.exe update
+C:\Users\jessi\.elan\bin\lake.exe build
+```
+
+### 2. Inference side
+
+```bash
+cd inference
+docker build -t lean-llm-inference .
+docker run -d -p 8080:8080 --name lean-llm-inference lean-llm-inference
+```
+
+### 3. Eval side
+
+```bash
+cd eval
+pip install -r requirements.txt
+python run_minif2f.py
+```
+
+### 4. Full verification loop
+
+```bash
+docker compose --env-file infra/verification-loop/.env.example up -d granite-verifier
+swipl -g "verify_with_retries('theorem demo : True := by trivial', 'ED25519_SIG', 3, Result), writeln(Result), halt" logic/verification_loop.pl
+```
+
+### 5. Shortcut targets
+
+```bash
+make lean-build
+make infra-up
+make eval
+```
+
+### 6. Parse smoke test
+
+```bash
+cd lean4
+C:\Users\jessi\.elan\bin\lake.exe exe verify -- --parse ../fixtures/sample_input.jsonl
+```
+
+## Hugging Face Readiness
+
+This repo is prepared for later Hugging Face publication with:
+
+- `.gitattributes` for LFS-managed weight files
+- `hf/README.md` model card template
+- `docs/HUGGINGFACE_PUBLISHING.md` publish checklist
+
+Recommended publish modes:
+
+1. code-only harness repo
+2. model repo for GGUF / safetensors
+3. Space repo for interactive verify loop UI
