## 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]: Tastyworks streaming deferred to Phase 10 as enhancement; batch pipeline uses Tradier REST throughout

### Pending Todos

None yet.

### Blockers/Concerns

- Historical IV data endpoint for IV Rank (52-week history) needs validation during Phase 1/3 planning
- Python version bump to >=3.11 required for tastytrade SDK (Phase 10)
- Tradier sandbox vs production Greeks fidelity unknown until Phase 1 implementation
