ExperimentTracker
ExperimentTracker manages shadow and limited-live A/B experiments, records matched-pair samples, computes confidence intervals, and emits a drift sign
What it does
ExperimentTracker manages shadow and limited-live A/B experiments, records matched-pair samples, computes confidence intervals, and emits a drift signal to StrategyRegistry when a variant underperforms.
Pipeline placement
Applies to: All strategies in shadow or limited-live experiment mode
Why it matters
| If this fails | Consequence |
|---|---|
| No experiment tracking | Promotions are made without statistical evidence; regressions go undetected. |
| Auto-promote without human sign-off | A variant with a transient winning streak is promoted before significance is established. |
Inputs
Polymarket inputs
| Input | Source | Required | Use |

Internal inputs
| Input | Source | Required | Use |
|---|---|---|---|
| Replay-tagged OperationsReport from shadow variant | gov.backtester | required | Populate matched-pair samples for the variant. |
| Live OperationsReport from control strategy | internal.report_bus | required | Baseline comparison for edge and fill quality. |
