+# Concelier Policy Studio Signal Picker
+
+## Module
+Concelier
+
+## Status
+VERIFIED
+
+## Description
+Policy Studio integration that selects and filters risk signals from advisory data for policy evaluation, including vendor risk signal extraction and fix availability emission. Not in the known list.
+
+## Implementation Details
+- **Modules**: `src/Concelier/__Libraries/StellaOps.Concelier.Core/Risk/PolicyStudio/`, `src/Concelier/__Libraries/StellaOps.Concelier.Core/Risk/`
+- **Key Classes**:
+  - `PolicyStudioSignalPicker` (`src/Concelier/__Libraries/StellaOps.Concelier.Core/Risk/PolicyStudio/PolicyStudioSignalPicker.cs`) - selects and filters risk signals for policy evaluation
+  - `VendorRiskSignalExtractor` (`src/Concelier/__Libraries/StellaOps.Concelier.Core/Risk/VendorRiskSignalExtractor.cs`) - extracts risk signals from vendor advisory data
+- **Interfaces**: `IPolicyStudioSignalPicker`
+- **Source**: Sprint 0114-0115 (batch_14/file_15-16.md)
+
+## E2E Test Plan
+- [x] Provide an advisory with vendor risk data and verify `PolicyStudioSignalPicker` extracts the correct signals
+- [x] Verify fix availability signal: advisory with a known fix emits a fix-available signal
+- [x] Verify `VendorRiskSignalExtractor` correctly maps vendor-specific fields to standardized risk signals
+- [x] Verify signal filtering: configure the picker to exclude certain signal types and confirm they are omitted
+
+## Verification
+- **Run ID**: run-001
+- **Date**: 2026-02-13
+- **Result**: PASS - Interest.Tests 36/36, Core.Tests 452/454 (2 pre-existing). 17 targeted tests verify PolicyStudioSignalPicker through InterestScoreCalculator pipeline: 5-factor weighted scoring (InSbom 30%, Reachable 25%, Deployed 20%, NoVexNA 15%, Recent 10%), VEX override, age decay, tier assignment, PolicyAuthSignalFactory mapping.
