+# Sprint 103 Plan: Verified Refactoring Patterns Library
+
+## Context
+
+Common adapter and migration fixes repeat. Sprint 103 codifies verified
+refactoring patterns as reusable, test-backed transformations.
+
+---
+
+## Goals
+
+1. Define a versioned library of verified refactor patterns
+2. Attach preconditions, postconditions, and risk profiles per pattern
+3. Auto-suggest applicable patterns from failure taxonomy
+4. Keep pattern application deterministic and auditable
+
+---
+
+## Steps
+
+### Step 1259: Refactor pattern schema and metadata model (12 tests)
+### Step 1260: Preconditions/postconditions validator for patterns (10 tests)
+### Step 1261: Pattern applicability matcher from graph context (10 tests)
+### Step 1262: Deterministic pattern executor wrapper (10 tests)
+### Step 1263: Pattern outcome scorer and rollback hooks (10 tests)
+### Step 1264: Pattern library governance workflow (8 tests)
+### Step 1265: `whetstone_list_verified_patterns` MCP tool (8 tests)
+### Step 1266: `whetstone_apply_verified_pattern` MCP tool (8 tests)
+### Step 1267: Pattern efficacy report artifact (8 tests)
+### Step 1268: Sprint 103 integration summary + regression (8 tests)
+
+---
+
+## Pattern Rule
+
+- Only certified patterns may run in Stable-tier pathways by default.
