Someone tried to build AGI. Pick up where they left off.
Someone tried to build AGI with microservices. They got halfway.
We have [the repo](https://github.com/andrewrgarcia/this-will-change-everything). It has a cognition engine, a memory layer, a reflex loop, and an event bus. It almost does something. There's even a [frontend](https://this-will-change-everything.vercel.app/) — signals, nodes, a P=NP claim, and a button that doesn't quite work.
Start from it. Take it somewhere real. You decide what it becomes — but it has to run, and it has to grow from what's already there.
See the [README](https://github.com/andrewrgarcia/this-will-change-everything/blob/main/README.md) for the full brief.

C++ Trading Engine — ongoing, team welcome (open source on completion)
## C++ trading engine — resolve all marked TODOs.
I will provide a seed repo: working build, passing tests, clean C++20. The system runs signal → order → fill → PnL end-to-end. Ten TODOs across four areas:
### Signals
- VAR(p) — Eigen OLS skeleton in place, algorithm documented
### Execution
- Resting limit orders with price-time priority
- Persistent order state (NEW → PARTIAL → FILLED → CANCELLED)
- Partial fills across book updates
- Nonlinear slippage (square-root impact, volatility dependence)
### Analytics
- Position-aware PnL and trade pairing (open ↔ close)
- Turnover, Sortino, volatility metrics
### Portfolio
- Fees / commissions in position accounting
Done when all existing tests pass, each TODO has coverage, and metrics.json is correct end-to-enC++ Trading Engine —d.
Stack: C++20, Eigen, CMake, nlohmann/json.
Repo is private during the project, open-sourced on completion.
