# 2026-02-15 12:00 — Legacy PTM90 LLM demo

## Summary
- Added a PTM90 legacy-style demo script that uses an LLM to map a natural-language target question into legacy `target_values` and then runs `LegacyPolicyLoopStrategy`.
- Added a PTM90 example netlist and bundled `ptm_90.txt` model file under `examples/circuits` for include-safe execution.

## Why
- Provide a runnable, legacy-compatible optimization flow that honors the new patch-only pipeline and guard semantics while preserving the legacy natural-language UX.

## How to use
- Run: `PYTHONPATH=src python examples/run_legacy_ptm90_llm.py --provider mock`
- For OpenAI: set `OPENAI_API_KEY` and pass `--provider openai --model gpt-4.1`.

## Files
- `examples/run_legacy_ptm90_llm.py`
- `examples/circuits/ptm90_basic_amp.sp`
- `examples/circuits/ptm_90.txt`
