+# Priority #4 - PR #29 Fixes & Resolution Summary
+
+**Date**: 2026-03-06  
+**Session**: Session 35 (Continuation)  
+**Status**: ✅ **READY FOR MERGE** (Validation & Pytest Fixes Complete)
+
+---
+
+## Executive Summary
+
+PR #29 (Priority #4: Automated Remediation Framework) was blocked by:
+1. ❌ Validation schema errors (validate-model.ps1)
+2. ❌ Pytest failures (AttributeError in model seeding)
+
+**All issues identified and fixed:**
+- ✅ Validation script corrected (PR #30)
+- ✅ Pytest admin tests now pass (9/9)
+- ✅ All commits pushed to GitHub
+- ✅ PR #29 ready for merge once PR #30 merged
+
+---
+
+## Issues Identified & Fixed
+
+### Issue #1: Validation Schema Mismatches
+
+**Problem**: `validate-model.ps1` checking for wrong field names and expecting all objects to have optional fields
+
+**Root Causes**:
+- Line 77: Checking for `key` field (doesn't exist) instead of `id`
+- Lines 78-79: Requiring `default_en`/`default_fr` fields (don't exist, use `en`/`fr`)
+- Line 73: Requiring `api_calls` on all screens (not all have this field)
+
+**Solution** (PR #30):
+```powershell
+# Before: if (-not $obj.key) { Fail ... }
+# After:  if (-not (HasProp $obj "id")) { Fail ... }
+
+# Made optional fields truly optional with null checks
+# Used safe property access (HasProp) for nested fields
+```
+
+**Verification**:
+```
+✅ PASS -- 0 violations
+58 repo_line coverage gap(s) [WARN - non-blocking]
+```
+
+---
+
+### Issue #2: Pytest AttributeError in Model Seeding
+
+**Problem**: Code calling dictionary methods on objects that might be strings
+
+**Root Causes**:
+- `api/server.py:151`: `obj.setdefault()` called on non-dict objects
+- `api/routers/admin.py:154`: `o.get("id")` called on strings
+
+**Solution** (Commit 3081fed):
+
+```python
+# api/server.py:148-153
+for obj in objects:
+    if isinstance(obj, dict):  # ← Added check
+        if "id" not in obj and "key" in obj:
+            obj["id"] = obj["key"]
+        obj.setdefault("source_file", f"model/{filename}")
+
+objects = [o for o in objects if isinstance(o, dict) and o.get("id")]  # ← Added check
+```
+
+```python
+# api/routers/admin.py:150-158 (Same pattern)
+for obj in objects:
+    if isinstance(obj, dict):  # ← Added check
+        if "id" not in obj and "key" in obj:
+            obj["id"] = obj["key"]
+
+objects = [o for o in objects if isinstance(o, dict) and o.get("id")]  # ← Added check
+```
