-# MARS-828: Enhanced Archival Strategies
-
-## Overview
-
-Implementation of flexible archival strategies for FILE_ARCHIVER package to support business requirements for different data retention policies across source systems.
-
-### Background
-
-**Issue**: Current FILE_ARCHIVER v2.0.0 uses fixed threshold-based archival (DAYS_FOR_ARCHIVE_THRESHOLD) which cannot accommodate:
-1. **LM/TOP sources**: Archive all data except current month
-2. **CSDB sources**: Archive only data older than 6 months
-
-**Root Cause**: Hardcoded WHERE clause in ARCHIVE_TABLE_DATA procedure:
-```sql
-WHERE extract(day from (systimestamp - workflow_start)) > DAYS_FOR_ARCHIVE_THRESHOLD
-```
-
-**Solution**: Introduce ARCHIVAL_STRATEGY configuration column with four strategies:
-- `THRESHOLD_BASED` - Days-based threshold (backward compatible)
-- `CURRENT_MONTH_ONLY` - Keep only current month data
-- `MINIMUM_AGE_MONTHS` - Archive data older than X months
-- `HYBRID` - Combination of current month and minimum age
-
-## Changes Made
-
-### Database Schema Changes
-**Table**: CT_MRDS.A_SOURCE_FILE_CONFIG
-
-**Before**:
-```sql
--- Only threshold-based configuration available
-DAYS_FOR_ARCHIVE_THRESHOLD NUMBER DEFAULT 30
-```
-
-**After**:
-```sql
--- Flexible strategy-based configuration
-ARCHIVAL_STRATEGY VARCHAR2(30) DEFAULT 'THRESHOLD_BASED' NOT NULL,
-MINIMUM_AGE_MONTHS NUMBER(3),
-DAYS_FOR_ARCHIVE_THRESHOLD NUMBER DEFAULT 30,
-CONSTRAINT CHK_ARCHIVAL_STRATEGY CHECK (ARCHIVAL_STRATEGY IN ('THRESHOLD_BASED', 'CURRENT_MONTH_ONLY', 'MINIMUM_AGE_MONTHS', 'HYBRID'))
-```
-
-**New Trigger**: TRG_BI_ARCHIVAL_STRATEGY_VAL
-- Validates MINIMUM_AGE_MONTHS required for strategies that need it
-- Ensures data integrity before insert/update
-
-### Package Changes
-**Package**: CT_MRDS.FILE_ARCHIVER
-
-**Version**: 2.0.0 → 3.0.0 (MAJOR - breaking changes to internal logic)
-
-**Specification Changes**:
-- Updated PACKAGE_VERSION: '2.0.0' → '3.0.0'
-- Updated VERSION_HISTORY with MARS-828 entry
-- Updated PACKAGE_BUILD_DATE to deployment date
-
-**Body Changes**:
-1. **New Function**: GET_ARCHIVAL_WHERE_CLAUSE(pSourceFileConfig) - Returns strategy-specific WHERE clause
-2. **Updated**: ARCHIVE_TABLE_DATA - Uses GET_ARCHIVAL_WHERE_CLAUSE for flexible filtering
-3. **Updated**: GATHER_TABLE_STAT - Uses GET_ARCHIVAL_WHERE_CLAUSE for statistics calculation
-
-**File Structure**:
-- **rollback/** - Backup of FILE_ARCHIVER v2.0.0 (for rollback)
-- **new_version/** - Updated FILE_ARCHIVER v3.0.0 (with strategy support)
-
-## Archival Strategies
-
-| Strategy | WHERE Clause Logic | Configuration Required | Use Case |
-|----------|-------------------|----------------------|----------|
-| `THRESHOLD_BASED` | `extract(day from (systimestamp - workflow_start)) > DAYS_FOR_ARCHIVE_THRESHOLD` | DAYS_FOR_ARCHIVE_THRESHOLD | Legacy compatibility |
-| `CURRENT_MONTH_ONLY` | `TRUNC(workflow_start, 'MM') < TRUNC(SYSDATE, 'MM')` | None | General sources (LM, TOP) |
-| `MINIMUM_AGE_MONTHS` | `workflow_start < ADD_MONTHS(TRUNC(SYSDATE, 'MM'), -X)` | MINIMUM_AGE_MONTHS | CSDB (6 months retention) |
-| `HYBRID` | Both CURRENT_MONTH_ONLY AND MINIMUM_AGE_MONTHS | MINIMUM_AGE_MONTHS | Advanced scenarios |
-
-## Configuration Examples
-
-```sql
--- LM/TOP sources: Archive everything except current month
-UPDATE A_SOURCE_FILE_CONFIG 
-SET ARCHIVAL_STRATEGY = 'CURRENT_MONTH_ONLY',
-    MINIMUM_AGE_MONTHS = NULL
-WHERE A_SOURCE_KEY IN ('LM', 'TOP');
-
--- CSDB: Archive only data older than 6 months
-UPDATE A_SOURCE_FILE_CONFIG 
-SET ARCHIVAL_STRATEGY = 'MINIMUM_AGE_MONTHS',
-    MINIMUM_AGE_MONTHS = 6
-WHERE A_SOURCE_KEY = 'CSDB' 
-  AND TABLE_ID IN ('DEBT', 'DEBT_DAILY');
-
--- Legacy sources: Keep existing threshold behavior
-UPDATE A_SOURCE_FILE_CONFIG 
-SET ARCHIVAL_STRATEGY = 'THRESHOLD_BASED',
-    DAYS_FOR_ARCHIVE_THRESHOLD = 30
-WHERE A_SOURCE_KEY = 'C2D';
-
--- Advanced hybrid: Current month + 3 months minimum
-UPDATE A_SOURCE_FILE_CONFIG 
-SET ARCHIVAL_STRATEGY = 'HYBRID',
-    MINIMUM_AGE_MONTHS = 3
-WHERE A_SOURCE_KEY = 'SPECIAL';
-```
-
-## Deployment
-
-### Prerequisites
-- **User**: ADMIN with full privileges
-- **Database**: Oracle 23ai
-- **ENV_MANAGER**: v3.x or higher
-- **FILE_MANAGER**: v3.x or higher  
-- **FILE_ARCHIVER**: v2.0.0 (will upgrade to v3.0.0)
-- **Table**: A_SOURCE_FILE_CONFIG must exist
-
-### Installation Steps
-
-**Option 1: Master Script (Recommended)**
-```powershell
-# Navigate to MARS-828 directory
-cd .\MARS_Packages\REL01_ADDITIONS\MARS-828
-
-# Execute installation (requires ADMIN user)
-sql "ADMIN/Cloudpass#34@ggmichalski_high" "@install_mars828.sql"
-
-# Log file created: log/INSTALL_MARS_828_<PDB>_<timestamp>.log
-```
-
-**Installation Workflow**:
-1. **Add Columns** - ARCHIVAL_STRATEGY, MINIMUM_AGE_MONTHS to A_SOURCE_FILE_CONFIG
-2. **Create Trigger** - Validation trigger TRG_BI_ARCHIVAL_STRATEGY_VAL
-3. **Deploy Package Spec** - FILE_ARCHIVER v3.0.0 specification
-4. **Deploy Package Body** - FILE_ARCHIVER v3.0.0 body with GET_ARCHIVAL_WHERE_CLAUSE
-5. **Verify Installation** - Check package compilation and structure
-6. **Track Version** - Record v3.0.0 in ENV_MANAGER
-7. **Verify Packages** - Check for untracked changes using ENV_MANAGER hash verification
-
-**Option 2: Using Get-Content**
-```powershell
-Get-Content "MARS_Packages\REL01_ADDITIONS\MARS-828\install_mars828.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
-```
-
-### Verification
-```sql
--- Check package compilation status
-SELECT object_name, object_type, status 
-FROM all_objects 
-WHERE owner = 'CT_MRDS'
-  AND object_name = 'FILE_ARCHIVER' 
-  AND object_type IN ('PACKAGE', 'PACKAGE BODY');
-
--- Verify package version
-SELECT CT_MRDS.FILE_ARCHIVER.GET_VERSION() FROM DUAL;
--- Expected: 3.0.0
-
--- Check new columns exist
-SELECT column_name, data_type, data_default 
-FROM all_tab_columns 
-WHERE owner = 'CT_MRDS' 
-  AND table_name = 'A_SOURCE_FILE_CONFIG'
-  AND column_name IN ('ARCHIVAL_STRATEGY', 'MINIMUM_AGE_MONTHS');
-
--- Test strategy configuration
-SELECT A_SOURCE_KEY, TABLE_ID, ARCHIVAL_STRATEGY, MINIMUM_AGE_MONTHS
-FROM CT_MRDS.A_SOURCE_FILE_CONFIG
-ORDER BY A_SOURCE_KEY, TABLE_ID;
-```
-
-### Rollback
-```powershell
-# Execute rollback script (requires ADMIN user)
-cd .\MARS_Packages\REL01_ADDITIONS\MARS-828
-sql "ADMIN/Cloudpass#34@ggmichalski_high" "@rollback_mars828.sql"
-
-# Log file created: log/ROLLBACK_MARS_828_<PDB>_<timestamp>.log
-```
-
-**Rollback Workflow**:
-1. **Restore Package Body** - FILE_ARCHIVER v2.0.0 body
-2. **Restore Package Spec** - FILE_ARCHIVER v2.0.0 specification
-3. **Drop Trigger** - Remove TRG_BI_ARCHIVAL_STRATEGY_VAL
-4. **Drop Columns** - Remove ARCHIVAL_STRATEGY, MINIMUM_AGE_MONTHS
-5. **Track Rollback** - Record v2.0.0 restoration in ENV_MANAGER
-6. **Verify Packages** - Check package hash consistency
-
-## Testing
-
-**Test Scripts**: Located in `test/` folder
-
-**Main Test Script**: test/test_archival_strategies.sql
-
-```sql
--- Test 1: CURRENT_MONTH_ONLY strategy
--- Expected: Archives data from previous months only
-SELECT COUNT(*) FROM table WHERE TRUNC(workflow_start, 'MM') < TRUNC(SYSDATE, 'MM');
-
--- Test 2: MINIMUM_AGE_MONTHS strategy (6 months)
--- Expected: Archives data older than 6 months
-SELECT COUNT(*) FROM table WHERE workflow_start < ADD_MONTHS(TRUNC(SYSDATE, 'MM'), -6);
-
--- Test 3: HYBRID strategy
--- Expected: Archives data from previous months AND older than X months
-```

-
-## Impact Analysis
-
-### Backward Compatibility
-✅ **FULLY BACKWARD COMPATIBLE**: Default ARCHIVAL_STRATEGY = 'THRESHOLD_BASED' maintains existing behavior for all sources without configuration changes.
-
-### Affected Procedures
-1. **ARCHIVE_TABLE_DATA** - Uses GET_ARCHIVAL_WHERE_CLAUSE for WHERE clause generation
-2. **GATHER_TABLE_STAT** - Uses GET_ARCHIVAL_WHERE_CLAUSE for statistics calculation
-
-### Configuration Migration
-No automatic migration required. New columns have sensible defaults:
-- ARCHIVAL_STRATEGY = 'THRESHOLD_BASED' (maintains current behavior)
-- MINIMUM_AGE_MONTHS = NULL (not required for THRESHOLD_BASED)
-
-## Version History

-# 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

-- 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.
