 ## Testing Propensity Signals in Sandbox
 
-In addition to product recommendations, the Sandbox returns agent-driven propensity signals under the `propensity` object for the [Fetch Recommendations API](../../../docs/recommendations/apis.md#fetch-recommendations). Request them using the `signals` parameter (`"signals": ["churn", "seatExpansion"]`); when omitted, all available signals are returned.
+In addition to product recommendations, the Sandbox returns agent-driven propensity signals under the `propensity` object for the [Fetch Recommendations API](../../../docs/recommendations/apis.md#fetch-recommendations). You can request these signals using the `includePropensity: true` request parameter.
 
 Each signal type (`churn`, `seatExpansion`) is returned as an array of prediction objects. Every prediction shares a common shape — `category`, `probability`, `refreshDate`, `reasons`, and `additionalDetails`. The `category` field indicates the scope of the prediction; the Sandbox seeds currently use `"allOfferings"`.
 
-A set of 13 predefined test seeds is configured in the Sandbox so you can exercise every combination of rating level and empty-array behavior during integration testing. Each seed returns a fixed response, so results are deterministic and repeatable.
+**Note:**
 
-### How probabilities are mapped
-
-Each model produces a percentile score (0–100) that is mapped to a `HIGH` / `MEDIUM` / `LOW` rating using the following thresholds:
-
-| Signal | HIGH | MEDIUM | LOW |
-|---|---|---|---|
-| churn | ≥ 95.0 | ≥ 91.0 | < 91.0 |
-| seatExpansion | ≥ 91.0 | ≥ 81.0 | < 81.0 |
-
-**Note:** The churn model is bimodal — only scores ≥ 91 qualify as `MEDIUM` or above. The `refreshDate` is the score date normalized to start-of-day UTC (for example, `2026-05-14` becomes `2026-05-14T00:00:00Z`). Seeds use `score_date = 2026-05-14` throughout.
+- A set of 13 predefined test seeds is configured in the Sandbox so you can exercise every combination of rating level and empty-array behavior during integration testing. Each seed returns a fixed response, so results are deterministic and repeatable.
+- Each customer is assigned one of the seeded responses randomly for testing. Once assigned, the seeded response does not change.
