# Reference fixtures
Synthetic reference outputs for Tier 1 indicators. Generated via
`python3 fixtures/generate_references.py`, which also writes synthetic sample
market data under `fixtures/market_data/`. Replace the generator with real
TA-Lib-backed outputs when available.
`sar.json` is the exception: it's generated by `fixtures/generate_sar_reference.py`
against the real TA-Lib C library (`talib.SAR`), not a Python
reimplementation — see that script's docstring for install/regeneration
steps.
