-# MARS-835: One-Time CSDB Data Export from Operational Database to External Tables
-
-## Overview
-This package performs a one-time bulk export of CSDB data from operational database tables (OU_CSDB schema) to new external tables in OCI buckets. The export uses DATA_EXPORTER v2.4.0 with per-column date format handling to move historical data to either DATA bucket (CSV format) or HIST bucket (Parquet format with Hive-style partitioning).
-
-**Migration Strategy:**
-- **Split Export (2 tables)**: DEBT, DEBT_DAILY - Last 6 months → DATA (CSV), Older data → HIST (Parquet)
-- **HIST Only (4 tables)**: INSTR_RAT_FULL, INSTR_DESC_FULL, ISSUER_RAT_FULL, ISSUER_DESC_FULL - All data → HIST (Parquet)
-
-**Key Transformations:**
-- Column rename: `A_ETL_LOAD_SET_FK` → `A_WORKFLOW_HISTORY_KEY` (all tables)
-- Column removal: DEBT (2 columns), DEBT_DAILY (6 columns) not required in new structure
-
-## Contents
-- `install_mars835.sql` - Master installation script with SPOOL logging
-- `rollback_mars835.sql` - Master rollback script
-- `01_MARS_835_*.sql` - Individual installation scripts
-- `91_MARS_835_*.sql` - Individual rollback scripts
-- `track_package_versions.sql` - Package version tracking
-- `verify_packages_version.sql` - Package verification
-
-## Prerequisites
-- Oracle Database 23ai
-- ADMIN user access (required for all MARS installations)
-- ENV_MANAGER v3.1.0+
-- Required schema privileges
-
-## Installation
-
-### Option 1: Master Script (Recommended)
-```powershell
-# IMPORTANT: Execute as ADMIN user for proper privilege management
-Get-Content "MARS_Packages/REL01_POST_DEACTIVATION/MARS-835/install_mars835.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
-
-# Log file created: log/INSTALL_MARS_835_<PDB>_<timestamp>.log
-```
-
-### Option 2: Individual Scripts
-```powershell
-# IMPORTANT: Execute as ADMIN user
-Get-Content "01_MARS_835_*.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
-Get-Content "02_MARS_835_*.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
-# ... etc
-```
-
-## Verification
-```sql
--- Verify package versions
-SELECT PACKAGE_NAME.GET_VERSION() FROM DUAL;
-
--- Check for errors (ADMIN user checks specific schema)
-SELECT * FROM ALL_ERRORS 
-WHERE OWNER = 'CT_MRDS'  -- Replace with target schema
-  AND NAME = 'PACKAGE_NAME';
-
--- Verify no untracked changes
-SELECT ENV_MANAGER.CHECK_PACKAGE_CHANGES('CT_MRDS', 'PACKAGE_NAME') FROM DUAL;
-```
-
-## Rollback
-```powershell
-# IMPORTANT: Execute as ADMIN user
-Get-Content "MARS_Packages/REL01_POST_DEACTIVATION/MARS-835/rollback_mars835.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
-
-**NOTE**: Rollback for data exports is **NOT RECOMMENDED** as it would delete exported files from OCI buckets. Only use rollback if export failed and needs to be restarted.
-```
-
-## Expected Changes
-
-### Data Export Summary
-**6 CSDB tables exported from OU_CSDB schema:**
-
-**Group 1: Split DATA + HIST (Time Critical)**
-1. **DEBT** - Last 6 months → DATA, Older → HIST
-2. **DEBT_DAILY** - Last 6 months → DATA, Older → HIST
-
-**Group 2: HIST Only (Weekend Bulk)**
-3. **INSTR_RAT_FULL** - All data → HIST
-4. **INSTR_DESC_FULL** - All data → HIST
-5. **ISSUER_RAT_FULL** - All data → HIST
-6. **ISSUER_DESC_FULL** - All data → HIST
-
-### Bucket Destinations (DEV environment)
-- **DATA Bucket**: `mrds_data_dev/ODS/CSDB/` (CSV format)
-- **HIST Bucket**: `mrds_hist_dev/ARCHIVE/CSDB/` (Parquet with partitioning)
-
-### Column Mappings
-- **All tables**: `A_ETL_LOAD_SET_FK` renamed to `A_WORKFLOW_HISTORY_KEY`
-- **DEBT**: Removed columns: `IDIRDEPOSITORY`, `VA_BONDDURATION`
-- **DEBT_DAILY**: Removed columns: `STEPID`, `PROGRAMNAME`, `PROGRAMCEILING`, `PROGRAMSTATUS`, `ISSUERNACE21SECTOR`, `INSTRUMENTQUOTATIONBASIS`
-
-## Testing
-
-### Post-Export Verification
-
-1. **Verify CSV files in DATA bucket** (DEBT, DEBT_DAILY - last 6 months):
-```sql
--- Check exported files
-SELECT object_name, bytes 
-FROM TABLE(DBMS_CLOUD.LIST_OBJECTS(
-    credential_name => 'DEF_CRED_ARN',
-    location_uri => 'https://objectstorage.region.oraclecloud.com/n/namespace/b/mrds_data_dev/o/ODS/CSDB/'
-)) WHERE object_name LIKE '%CSDB_DEBT%';
-```
-
-2. **Verify Parquet files in HIST bucket** (all 6 tables):
-```sql
--- Check archived files with Hive partitioning
-SELECT object_name, bytes 
-FROM TABLE(DBMS_CLOUD.LIST_OBJECTS(
-    credential_name => 'DEF_CRED_ARN',
-    location_uri => 'https://objectstorage.region.oraclecloud.com/n/namespace/b/mrds_hist_dev/o/ARCHIVE/CSDB/'
-)) WHERE object_name LIKE '%PARTITION_YEAR=%';
-```
-
-3. **Validate row counts match source tables**:
-```sql
--- Compare counts between source and exported data
-SELECT COUNT(*) FROM OU_CSDB.DEBT;
-SELECT COUNT(*) FROM ODS.CSDB_DEBT_ODS;  -- External table pointing to DATA
-SELECT COUNT(*) FROM ODS.CSDB_DEBT_ARCHIVE;  -- External table pointing to HIST
-```
-
-4. **Verify column mappings**:
-```sql
--- Check A_WORKFLOW_HISTORY_KEY exists in exported data
-SELECT A_WORKFLOW_HISTORY_KEY, COUNT(*) 
-FROM ODS.CSDB_DEBT_ARCHIVE 
-GROUP BY A_WORKFLOW_HISTORY_KEY;
-```
-
-## Known Issues
-
-### Timing Constraints
-- **DATA exports (DEBT, DEBT_DAILY)**: Must execute during parallel old+new loads phase after Production deployment
-- **HIST exports (all 6 tables)**: Can run anytime, recommended for weekend bulk execution to avoid interference
-
-### Environment-Specific Configuration
-- Bucket names must be adjusted for each environment:
-  - DEV: `mrds_data_dev`, `mrds_hist_dev`
-  - TEST: `mrds_data_test`, `mrds_hist_test`  
-  - PROD: `mrds_data_prod`, `mrds_hist_prod`
-
-### Data Cutoff Date
-- Export scripts use 6-month cutoff date calculated as `ADD_MONTHS(SYSDATE, -6)`
-- Verify cutoff aligns with business requirements before execution
-
-### One-Time Execution
-- This is a **ONE-TIME data migration** package
-- After successful execution, package should be **deactivated** (moved to REL01_POST_DEACTIVATION)
-- Do not re-run unless explicitly required for data refresh

-# MARS-835: Required External Tables for Smart Column Mapping
-
-## Overview
-This document lists all external tables required for MARS-835 data exports using DATA_EXPORTER v2.4.0 with Smart Column Mapping feature.
-
-**Purpose**: Smart Column Mapping ensures CSV files are generated with columns in the EXACT order expected by external tables, preventing NULL values due to Oracle's positional CSV mapping.
-
----
-
-## Required External Tables
-
-### Group 1: DATA Bucket (CSV Format) - **CRITICAL**
-
-#### 1. ODS.CSDB_DEBT_DATA_ODS
-- **Source Table**: OU_CSDB.LEGACY_DEBT
-- **Format**: CSV
-- **Bucket**: DATA (mrds_data_dev/ODS/CSDB/CSDB_DEBT/)
-- **Key Column Mapping**: A_ETL_LOAD_SET_FK → A_WORKFLOW_HISTORY_KEY (position 2 recommended)
-- **Critical**: Must use Smart Column Mapping to avoid NULL values in A_WORKFLOW_HISTORY_KEY
-
-#### 2. ODS.CSDB_DEBT_DAILY_DATA_ODS
-- **Source Table**: OU_CSDB.LEGACY_DEBT_DAILY
-- **Format**: CSV
-- **Bucket**: DATA (mrds_data_dev/ODS/CSDB/CSDB_DEBT_DAILY/)
-- **Key Column Mapping**: A_ETL_LOAD_SET_FK → A_WORKFLOW_HISTORY_KEY (position 2 recommended)
-- **Critical**: Must use Smart Column Mapping to avoid NULL values in A_WORKFLOW_HISTORY_KEY
-
----
-
-### Group 2: ARCHIVE Bucket (Parquet Format) - **RECOMMENDED**
-
-#### 3. ODS.CSDB_DEBT_ARCHIVE
-- **Source Table**: OU_CSDB.LEGACY_DEBT
-- **Format**: Parquet with Hive partitioning
-- **Bucket**: ARCHIVE (mrds_hist_dev/ARCHIVE/CSDB/CSDB_DEBT/)
-- **Key Column Mapping**: A_ETL_LOAD_SET_FK → A_WORKFLOW_HISTORY_KEY
-- **Note**: Parquet uses schema-based mapping (column order less critical but Smart Column Mapping ensures consistency)
-
-#### 4. ODS.CSDB_DEBT_DAILY_ARCHIVE
-- **Source Table**: OU_CSDB.LEGACY_DEBT_DAILY
-- **Format**: Parquet with Hive partitioning
-- **Bucket**: ARCHIVE (mrds_hist_dev/ARCHIVE/CSDB/CSDB_DEBT_DAILY/)
-- **Key Column Mapping**: A_ETL_LOAD_SET_FK → A_WORKFLOW_HISTORY_KEY
-
-#### 5. ODS.CSDB_INSTR_RAT_FULL_ARCHIVE
-- **Source Table**: OU_CSDB.LEGACY_INSTR_RAT_FULL
-- **Format**: Parquet with Hive partitioning
-- **Bucket**: ARCHIVE (mrds_hist_dev/ARCHIVE/CSDB/CSDB_INSTR_RAT_FULL/)
-- **Key Column Mapping**: A_ETL_LOAD_SET_FK → A_WORKFLOW_HISTORY_KEY
-
-#### 6. ODS.CSDB_INSTR_DESC_FULL_ARCHIVE
-- **Source Table**: OU_CSDB.LEGACY_INSTR_DESC_FULL
-- **Format**: Parquet with Hive partitioning
-- **Bucket**: ARCHIVE (mrds_hist_dev/ARCHIVE/CSDB/CSDB_INSTR_DESC_FULL/)
-- **Key Column Mapping**: A_ETL_LOAD_SET_FK → A_WORKFLOW_HISTORY_KEY
-
-#### 7. ODS.CSDB_ISSUER_RAT_FULL_ARCHIVE
-- **Source Table**: OU_CSDB.LEGACY_ISSUER_RAT_FULL
-- **Format**: Parquet with Hive partitioning
-- **Bucket**: ARCHIVE (mrds_hist_dev/ARCHIVE/CSDB/CSDB_ISSUER_RAT_FULL/)
-- **Key Column Mapping**: A_ETL_LOAD_SET_FK → A_WORKFLOW_HISTORY_KEY
-
-#### 8. ODS.CSDB_ISSUER_DESC_FULL_ARCHIVE
-- **Source Table**: OU_CSDB.LEGACY_ISSUER_DESC_FULL
-- **Format**: Parquet with Hive partitioning
-- **Bucket**: ARCHIVE (mrds_hist_dev/ARCHIVE/CSDB/CSDB_ISSUER_DESC_FULL/)
-- **Key Column Mapping**: A_ETL_LOAD_SET_FK → A_WORKFLOW_HISTORY_KEY

-## External Table Column Order Requirements
-
-### **CRITICAL for CSV Tables** (DATA bucket):
-
-All CSV external tables MUST have **A_WORKFLOW_HISTORY_KEY at position 2**:
-
-```
-Position 1: A_KEY (NUMBER)
-Position 2: A_WORKFLOW_HISTORY_KEY (NUMBER)  ← MUST BE HERE!
-Position 3+: Other columns in any order
-```
-
-**Reason**: Oracle External Tables with CSV format use **positional mapping** (ignore header row). If source table has A_ETL_LOAD_SET_FK at position 72, but CSV puts it at position 72 while external table expects A_WORKFLOW_HISTORY_KEY at position 2, the external table will try to read position 2 (which might be a DATE column) as NUMBER → conversion fails → NULL value.
-
-**Solution**: Smart Column Mapping (v2.4.0) generates CSV columns in EXTERNAL TABLE order, ensuring position 2 has the correct NUMBER value.
-
-### **OPTIONAL for Parquet Tables** (ARCHIVE bucket):
-
-Parquet format uses **schema-based mapping** (column names). Column order doesn't matter, but Smart Column Mapping provides consistency.
-
----
-
-## Creation Script Example
-
-### CSV External Table (CRITICAL - Correct Column Order)
-
-```sql
--- Example: ODS.CSDB_DEBT_DATA_ODS
--- IMPORTANT: A_WORKFLOW_HISTORY_KEY must be at position 2!
-
-BEGIN
-    ODS.FILE_MANAGER_ODS.CREATE_EXTERNAL_TABLE(
-        pTableName => 'CSDB_DEBT_DATA_ODS',
-        pTemplateTableName => 'CT_ET_TEMPLATES.CSDB_DEBT_TEMPLATE',
-        pPrefix => 'ODS/CSDB/CSDB_DEBT',
-        pBucketUri => CT_MRDS.ENV_MANAGER.gvDataBucketUri,
-        pFormat => 'CSV'  -- Uses positional mapping!
-    );
-END;
-/
-
--- Verify column order (A_WORKFLOW_HISTORY_KEY should be position 2)
-SELECT column_id, column_name, data_type
-FROM all_tab_columns
-WHERE table_name = 'CSDB_DEBT_DATA_ODS'
-  AND owner = 'ODS'
-ORDER BY column_id;
-```
-
-### Parquet External Table (Optional Column Order)
-
-```sql
--- Example: ODS.CSDB_DEBT_ARCHIVE
--- Column order flexible (schema-based mapping)
-
-BEGIN
-    ODS.FILE_MANAGER_ODS.CREATE_EXTERNAL_TABLE(
-        pTableName => 'CSDB_DEBT_ARCHIVE',
-        pTemplateTableName => 'CT_ET_TEMPLATES.CSDB_DEBT_TEMPLATE',
-        pPrefix => 'ARCHIVE/CSDB/CSDB_DEBT',
-        pBucketUri => CT_MRDS.ENV_MANAGER.gvArchiveBucketUri,
-        pFormat => 'PARQUET'  -- Uses schema-based mapping
-    );
-END;
-/
-```
-
----
-
-## Template Tables Required
-
-All external tables require corresponding template tables in CT_ET_TEMPLATES schema:
-
-- `CT_ET_TEMPLATES.CSDB_DEBT_TEMPLATE`
-- `CT_ET_TEMPLATES.CSDB_DEBT_DAILY_TEMPLATE`
-- `CT_ET_TEMPLATES.CSDB_INSTR_RAT_FULL_TEMPLATE`
-- `CT_ET_TEMPLATES.CSDB_INSTR_DESC_FULL_TEMPLATE`
-- `CT_ET_TEMPLATES.CSDB_ISSUER_RAT_FULL_TEMPLATE`
-- `CT_ET_TEMPLATES.CSDB_ISSUER_DESC_FULL_TEMPLATE`
-
-**Note**: Template tables must be created by ADMIN or CT_ET_TEMPLATES user (MRDS_LOADER cannot create them).
-
----
-
-## Verification Checklist
-
-Before running MARS-835 exports:
-
-- [ ] All 8 external tables exist in ODS schema
-- [ ] CSV tables (DATA bucket) have A_WORKFLOW_HISTORY_KEY at position 2
-- [ ] Template tables exist in CT_ET_TEMPLATES schema
-- [ ] MRDS_LOADER has EXECUTE privilege on ODS.FILE_MANAGER_ODS
-- [ ] ODS schema has access to CT_MRDS.ENV_MANAGER for logging
-- [ ] DATA_EXPORTER v2.4.0 deployed with Smart Column Mapping feature
-
----
-
-## Testing Verification
-
-After export, verify A_WORKFLOW_HISTORY_KEY is not NULL:
-
-```sql
--- CSV tables (should be 100% populated)
-SELECT 'CSDB_DEBT_DATA_ODS' AS TABLE_NAME,
-       COUNT(*) AS TOTAL_ROWS,
-       COUNT(A_WORKFLOW_HISTORY_KEY) AS NON_NULL_COUNT,
-       ROUND(COUNT(A_WORKFLOW_HISTORY_KEY) * 100.0 / NULLIF(COUNT(*), 0), 2) AS SUCCESS_RATE_PCT
-FROM ODS.CSDB_DEBT_DATA_ODS;
-
-SELECT 'CSDB_DEBT_DAILY_DATA_ODS' AS TABLE_NAME,
-       COUNT(*) AS TOTAL_ROWS,
-       COUNT(A_WORKFLOW_HISTORY_KEY) AS NON_NULL_COUNT,
-       ROUND(COUNT(A_WORKFLOW_HISTORY_KEY) * 100.0 / NULLIF(COUNT(*), 0), 2) AS SUCCESS_RATE_PCT
-FROM ODS.CSDB_DEBT_DAILY_DATA_ODS;
-
--- Parquet tables (should also be 100% populated)
-SELECT 'CSDB_DEBT_ARCHIVE' AS TABLE_NAME,
-       COUNT(*) AS TOTAL_ROWS,
-       COUNT(A_WORKFLOW_HISTORY_KEY) AS NON_NULL_COUNT,
-       ROUND(COUNT(A_WORKFLOW_HISTORY_KEY) * 100.0 / NULLIF(COUNT(*), 0), 2) AS SUCCESS_RATE_PCT
-FROM ODS.CSDB_DEBT_ARCHIVE;
-```
-
-**Expected Result**: SUCCESS_RATE_PCT = 100.00 for all tables

+# MARS-1409-POSTHOOK: Backfill A_WORKFLOW_HISTORY_KEY for existing records
+
+## Overview
+
+Post-hook for MARS-1409. Backfills `A_WORKFLOW_HISTORY_KEY` in
+`CT_MRDS.A_SOURCE_FILE_RECEIVED` for historical records that existed before
+MARS-1409 was installed.
+
+Matches records by `SOURCE_FILE_NAME` against `file$name` in the corresponding
+ODS table (`ODS.<TABLE_ID>_ODS`) for each `INPUT` source configuration.
+
+## Contents
+
+| File | Description |
+|------|-------------|
+| `install_mars1409_posthook.sql` | Master installation script (SPOOL, ACCEPT, quit) |
+| `rollback_mars1409_posthook.sql` | Master rollback script (SPOOL, ACCEPT, quit) |
+| `01_MARS_1409_POSTHOOK_update_existing_workflow_keys.sql` | Backfill UPDATE script |
+| `91_MARS_1409_POSTHOOK_rollback_workflow_keys.sql` | Clear backfilled values |
+| `track_package_versions.sql` | Universal version tracking (no packages changed) |
+| `verify_packages_version.sql` | Universal package verification |
+| `README.md` | This file |
+
+## Prerequisites
+
+- MARS-1409 installed (`A_WORKFLOW_HISTORY_KEY` column must exist in `CT_MRDS.A_SOURCE_FILE_RECEIVED`)
+- ODS tables populated with ingested data
+- ADMIN user with access to CT_MRDS and ODS schemas
+
+## Installation
+
+```powershell
+# Execute as ADMIN user
+Get-Content "MARS_Packages/REL02_POST/MARS-1409-POSTHOOK/install_mars1409_posthook.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
+```
+
+Log file created automatically: `log/INSTALL_MARS_1409_POSTHOOK_<PDB>_<timestamp>.log`
+
+## What it does
+
+- Iterates all `INPUT` source configurations from `CT_MRDS.A_SOURCE_FILE_CONFIG`
+- For each config, joins `A_SOURCE_FILE_RECEIVED` with `ODS.<TABLE_ID>_ODS` on `SOURCE_FILE_NAME = file$name`
+- Updates `A_WORKFLOW_HISTORY_KEY` for records with statuses:
+  `VALIDATED`, `READY_FOR_INGESTION`, `INGESTED`, `ARCHIVED`, `ARCHIVED_AND_TRASHED`, `ARCHIVED_AND_PURGED`
+- Skips configs with no NULL records or missing ODS tables
+- Prints summary with counts per config and overall totals
+
+## Rollback
+
+```powershell
+# Execute as ADMIN user
+Get-Content "MARS_Packages/REL02_POST/MARS-1409-POSTHOOK/rollback_mars1409_posthook.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
+```
+
+Rollback clears all non-NULL `A_WORKFLOW_HISTORY_KEY` values from `A_SOURCE_FILE_RECEIVED`.
+The trigger installed by MARS-1409 will repopulate new records automatically.

+
+## Status
+**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. **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

+## Post-Installation Verification
+
+### Check migration results:
+```sql
+-- Count updated records
+SELECT 
+    CASE WHEN A_WORKFLOW_HISTORY_KEY IS NOT NULL THEN 'POPULATED' ELSE 'NULL' END as STATUS,
+    COUNT(*) as RECORD_COUNT
+FROM CT_MRDS.A_SOURCE_FILE_RECEIVED
+GROUP BY CASE WHEN A_WORKFLOW_HISTORY_KEY IS NOT NULL THEN 'POPULATED' ELSE 'NULL' END;
+
+-- 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)
