Invariant does not record what people say they believed.
It records what their capital repeatedly depended on — and shows how exposed they are if that dependence fails.
Invariant is built on one locked concept. Everything else follows from it.
An artefact becomes load-bearing when two conditions are met simultaneously:
Artefacts that persist without being tested are labelled: persistent but untested. This is not failure — it is information about current exposure.
When capital exposure changes, Invariant produces one object automatically. The Evidence Bundle. A reproducible record of what that decision depended on — replayable under scrutiny.
| Component | Probe | Status |
|---|---|---|
| crude_price_feed | Removal test | UNTESTED |
| liquidity_model | Alt simulation | PARTIAL |
| decay_parameter | Retuning | PARTIAL |
| vol_regime_filter | Regime switch | TESTED |
crude_price_feed drives 43% of this decision. It has never been tested under removal. If invalidated, ~40% of factor exposure is affected simultaneously.
The deck, the demo, and the code. Three things that didn't exist a week ago.
Three realistic fund scenarios. Evidence Bundles generated automatically. Runs in Jupyter — no setup required to view.

github.comInvariant survives success, politics, and time because it does not ask for virtue, acknowledgement, or confession.
Memory must resist reinterpretation. Structure beats prose. Dependence is observed, not reported.
Evidence must bind success as tightly as failure. Wins rewrite history more aggressively than losses.
No decision is blocked. But no important decision is forgettable.
Influence is acknowledged and constrained. Nothing is hidden. Nothing is silent.
Invariant never comforts. It confronts reality under power.
We are looking for 3–5 quant desks willing to run a 60-day pilot. Proof-of-value metrics agreed upfront. First live exposure replay is the milestone.
If the problem is real at your desk — or you know someone it would be real for — get in touch.
