+# Scavenge Script Tests Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Add focused unit tests for `Scripts/scavenge.ps1` that cover request construction and authentication header behavior.
+
+**Architecture:** Keep the existing script unchanged unless a test exposes a real behavioral gap. Add one Pester test file alongside the existing script tests so the new coverage stays in the same style and location as the current PowerShell tests.
+
+**Tech Stack:** PowerShell, Pester
+
+## Global Constraints
+
+- Keep tests local and deterministic; do not hit the real `http://localhost:2113` service.
+- Follow the existing script-test style in `Scripts/Tests/Invoke-DailySettlementProcessing.Tests.ps1`.
+
+---
+
+### Task 1: Add scavenge script tests
+
+**Files:**
+- Create: `Scripts/Tests/Scavenge.Tests.ps1`
+
+**Interfaces:**
+- Consumes: `Scripts/scavenge.ps1`
+- Produces: Pester coverage for the POST target URI and auth header branching
+
+- [ ] **Step 1: Write the test file**
