Vendor free_llm_router and layer an LLM sentiment tier on top of the existing FinBERT -> XLM-RoBERTa -> VADER chain in processors/sentiment.py. The LLM returns financial sentiment with direction (bullish/bearish), which keyword/FinBERT scoring conflates with tone. Falls through to the existing chain on any failure, so reliability is unchanged. - Sync asyncio.run bridge (Celery workers have no running loop). - Enabled by default when the package is present; FREE_LLM_ENABLED=false to disable. - .env.example documents per-provider keys.

What
Adds an optional LLM sentiment tier on top of the existing FinBERT → XLM-RoBERTa → VADER chain, powered by a vendored
free_llm_router(perpetually-free providers).Why
Keyword/FinBERT scoring conflates tone with market direction — e.g. "rate hike" reads positive in tone but is bearish for equities. The LLM returns explicit
direction(bullish/bearish/neutral) alongside the score.Behavior
asyncio.runbridge (Celery workers have no running event loop).FREE_LLM_ENABLED=falsedisables it.Verified
Compiles clean; router internals smoke-tested. Not yet exercised with live keys.
