# Project State
## Project Reference

## Accumulated Context
### Decisions
Decisions are logged in PROJECT.md Key Decisions table.
Recent decisions affecting current work:
- [Roadmap]: Phases 2, 3, 4 can run in parallel after Phase 1 (all depend only on Tradier data layer)
- [Roadmap]: SVI volatility surface isolated in its own phase (Phase 5) due to highest implementation risk
- [Roadmap]: All deterministic math in Phase 2 as standalone module before any agents consume it (critical pitfall mitigation)
- [Roadmap]: Tastytrade streaming deferred to Phase 10 as enhancement; batch pipeline uses Tradier REST throughout
- [Phase 01]: Session cache stores OptionsChain objects keyed by symbol:min_dte:max_dte
- [Phase 01]: Dual return pattern: string for LLM tools, dataclass for computation modules
- [Phase 01]: Tradier is sole vendor for options_chain category (no fallback yet)
- [Phase 01]: Options @tool functions convert list results to comma-separated strings for LLM readability
### Pending Todos
None yet.
### Blockers/Concerns
- Historical IV data endpoint for IV Rank (52-week history) needs validation during Phase 1/3 planning
- **Python >=3.11** is the project baseline (see `pyproject.toml` and `.planning/PROJECT.md`); required for the community **tastytrade** SDK used in Phase 10 — use a single venv (e.g. `uv venv --python 3.13`) for the whole repo; no separate “Phase 10 only” interpreter is required if the environment already meets >=3.11
- Tradier sandbox vs production Greeks fidelity unknown until Phase 1 implementation
