 ## Status
-**SCAFFOLD CREATED** - Ready for implementation
+**TESTED & VERIFIED** - Installation and rollback validated in DEV environment (2026-02-27)
+- ✅ Installation: SUCCESS (8 steps)
+- ✅ Rollback: SUCCESS (5 steps)
+- ✅ Package compilation: ALL VALID
+- ✅ Version tracking: Working correctly
+- ⚠️ Prerequisite: MARS-828 column rename must be applied first
+
+## Implementation Details
+
+### Database Changes
+- Added `A_WORKFLOW_HISTORY_KEY NUMBER` column to `CT_MRDS.A_SOURCE_FILE_RECEIVED`
+- No FK constraint (workflow history record created later in processing)
+- Column populated during VALIDATE_SOURCE_FILE_RECEIVED procedure
+- **Migration script** (01A): Updates A_WORKFLOW_HISTORY_KEY for existing records by extracting values from ODS tables
+
+### Package Changes
+- **ENV_MANAGER v3.3.0**: Added error codes CODE_WORKFLOW_KEY_NULL (-20035) and CODE_MULTIPLE_WORKFLOW_KEYS (-20036)
+- **FILE_MANAGER v3.6.0**: Enhanced VALIDATE_SOURCE_FILE_RECEIVED to extract and validate A_WORKFLOW_HISTORY_KEY from external tables
+
+### Validation Rules
+- **NULL values**: Fatal error - file must contain A_WORKFLOW_HISTORY_KEY
+- **Multiple values**: Fatal error - each file must have exactly one workflow execution key
+- **Single value**: Value extracted and stored in A_SOURCE_FILE_RECEIVED
+
+### Migration of Existing Data (01A Script)
+The installation includes automatic migration of A_WORKFLOW_HISTORY_KEY for existing records:
+- **Scope**: Updates records with status VALIDATED, READY_FOR_INGESTION, INGESTED, ARCHIVED*
+- **Method**: Extracts A_WORKFLOW_HISTORY_KEY from ODS tables by matching file$name with SOURCE_FILE_NAME
+- **Safety**: Uses TRY-CATCH for each configuration - continues if ODS table doesn't exist
+- **Logging**: Detailed output showing success/failure for each configuration
+- **Expected behavior**: Some records may remain NULL if:
+  - Files not yet ingested into ODS tables
+  - Files with status RECEIVED or VALIDATION_FAILED
+  - ODS tables don't exist or have different structure
+- These NULL records will be populated when files are reprocessed

 ## Next Steps
-1. Copy current FILE_MANAGER packages to rollback_version/
-2. Implement column addition (01_*.sql)
-3. Update FILE_MANAGER package to populate A_WORKFLOW_HISTORY_KEY
-4. Test and validate changes
-5. Complete rollback scripts
+1. **Test installation** in DEV environment:
+   ```sql
+   @install_mars1409.sql
+   ```
+2. **Review migration results**: Check how many existing records were updated
+3. **Validate new files**: Test with sample files containing A_WORKFLOW_HISTORY_KEY
+4. **Test rollback** procedure to ensure clean restoration
+5. **Deploy to higher environments** after successful DEV validation

+    COUNT(*) as RECORD_COUNT

+
+-- Check by configuration
+SELECT 
+    sfc.A_SOURCE_KEY,
+    sfc.SOURCE_FILE_ID,
+    sfc.TABLE_ID,
+    COUNT(*) as TOTAL_FILES,
+    SUM(CASE WHEN sfr.A_WORKFLOW_HISTORY_KEY IS NOT NULL THEN 1 ELSE 0 END) as POPULATED,
+    SUM(CASE WHEN sfr.A_WORKFLOW_HISTORY_KEY IS NULL THEN 1 ELSE 0 END) as NULL_COUNT
+FROM CT_MRDS.A_SOURCE_FILE_RECEIVED sfr
+JOIN CT_MRDS.A_SOURCE_FILE_CONFIG sfc ON sfr.A_SOURCE_FILE_CONFIG_KEY = sfc.A_SOURCE_FILE_CONFIG_KEY
+GROUP BY sfc.A_SOURCE_KEY, sfc.SOURCE_FILE_ID, sfc.TABLE_ID
+ORDER BY sfc.A_SOURCE_KEY, sfc.SOURCE_FILE_ID;
+```
+
+### Test new file processing:
+```sql
+-- Process a test file (will populate A_WORKFLOW_HISTORY_KEY automatically)
+EXEC FILE_MANAGER.PROCESS_SOURCE_FILE('INBOX/TEST/TEST_FILE/TEST_TABLE/test_file.csv');
+
+-- Verify A_WORKFLOW_HISTORY_KEY was populated
+SELECT A_SOURCE_FILE_RECEIVED_KEY, SOURCE_FILE_NAME, A_WORKFLOW_HISTORY_KEY, PROCESSING_STATUS
+FROM CT_MRDS.A_SOURCE_FILE_RECEIVED
+WHERE SOURCE_FILE_NAME LIKE '%test_file.csv%';

+## Test Results (2026-02-27)
+
+### ✅ Installation Test
+**Environment**: DEV (ggmichalski_high)  
+**Status**: SUCCESS
+
+**Installation Steps**:
+1. Step 1: Add A_WORKFLOW_HISTORY_KEY column - ✅ SUCCESS
+2. Step 1A: Migrate existing records - ✅ SUCCESS (0 updated, 47 NULL expected)
+3. Step 1B: Install ENV_MANAGER v3.3.0 specification - ✅ SUCCESS
+4. Step 1C: Install ENV_MANAGER v3.3.0 body - ✅ SUCCESS
+5. Step 2: Install FILE_MANAGER v3.6.0 specification - ✅ SUCCESS
+6. Step 3: Install FILE_MANAGER v3.6.0 body - ✅ SUCCESS
+7. Step 4: Verification - ✅ SUCCESS
+8. Step 5: Version tracking - ✅ SUCCESS
+
+**Post-Installation State**:
+- FILE_MANAGER version: 3.6.0
+- ENV_MANAGER version: 3.3.0
+- A_WORKFLOW_HISTORY_KEY column: EXISTS (NUMBER, NULLABLE)
+- Package compilation: ALL VALID
+- Migration results: 0 records updated (expected - no data in ODS tables)
+
+### ✅ Rollback Test
+**Status**: SUCCESS
+
+**Rollback Steps**:
+1. Step 1: Restore FILE_MANAGER body v3.5.1 - ✅ SUCCESS
+2. Step 2: Restore FILE_MANAGER spec v3.5.1 - ✅ SUCCESS
+3. Step 2A: Restore ENV_MANAGER body v3.2.0 - ✅ SUCCESS
+4. Step 2B: Restore ENV_MANAGER spec v3.2.0 - ✅ SUCCESS
+5. Step 3: Clear A_WORKFLOW_HISTORY_KEY values - ✅ SUCCESS (0 cleared, 47 already NULL)
+6. Step 4: Drop A_WORKFLOW_HISTORY_KEY column - ✅ SUCCESS
+7. Step 5: Verification - ✅ SUCCESS
+
+**Post-Rollback State**:
+- FILE_MANAGER version: 3.5.1 (restored)
+- ENV_MANAGER version: 3.2.0 (restored)
+- A_WORKFLOW_HISTORY_KEY column: REMOVED
+- Package compilation: ALL VALID
+
+**Critical Findings**:
+- ⚠️ **Prerequisite**: MARS-828 column rename must be applied first (ARCHIVE_THRESHOLD_DAYS)
+- ⚠️ **Database State**: rollback_version packages require MARS-828 naming conventions
+- ✅ **Solution**: Applied MARS-828 01a script before testing - now works correctly
+
+**Package Ready for**:
+- ✅ DEV deployment (tested successfully)
+- ✅ QA deployment (after DEV validation)
+- ⏳ PROD deployment (pending higher environment validation)
