+# 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

+-- Count updated records
+SELECT 
+    CASE WHEN A_WORKFLOW_HISTORY_KEY IS NOT NULL THEN 'POPULATED' ELSE 'NULL' END as STATUS,
+    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)

EXPORT_TABLE_DATA_BY_DATE passes PARQUET - string data was being corrupted (single " doubled to ""). Parquet is binary and needs no quote escaping.' || CHR(10) ||

+       'v2.6.2 (2026-01-28): CRITICAL FIX - Race condition when multiple exports run simultaneously. Changed DELETE to filter by age (>24h) instead of deleting all COMPLETED chunks. Prevents concurrent sessions from deleting each other chunks. Session-safe cleanup with TASK_NAME filtering. Enables true parallel execution of multiple export jobs.' || CHR(10) ||
+       'v2.6.1 (2026-01-28): Added DELETE_FAILED_EXPORT_FILE procedure to clean up partial/corrupted files before retry.

Prevents duplicate file creation when parallel tasks fail (e.g., 22 partitions with 16 threads, 3 failures no longer duplicates 19 successful exports).' || CHR(10) ||
+       'v2.5.0 (2026-01-26): Added recorddelimiter parameter with CRLF (CHR(13)||CHR(10)) for CSV exports to ensure Windows-compatible line endings. Improves cross-platform compatibility when CSV files are opened in Windows applications (Notepad, Excel).' || CHR(10) ||
+       'v2.4.0 (2026-01-11): Added pTemplateTableName parameter for per-column date format configuration. Implements dynamic query building with TO_CHAR for each date/timestamp column using FILE_MANAGER.GET_DATE_FORMAT. Supports 3-tier hierarchy: column-specific, template DEFAULT, global fallback. Eliminates single dateformat limitation of DBMS_CLOUD.EXPORT_DATA.' || CHR(10) ||

+# MARS-1005-PREHOOK: Fix DATA_EXPORTER RFC 4180 Compliance + Parquet Format Support
+
+## Overview
+
+Pre-hook for MARS-1005. Deploys an updated `CT_MRDS.DATA_EXPORTER` package (v2.17.0)
+that resolves two export format bugs:
+
+1. **RFC 4180 compliance (v2.15.0 / v2.16.0):** Previous versions used `escape=true`
+   in `DBMS_CLOUD.EXPORT_DATA`, producing backslash-escaped embedded quotes (`\"`).
+   ODS external tables (`FIELDS CSV WITHOUT EMBEDDED`) expect RFC 4180 doubling (`""`).
+   Fix: removed `escape=true`; implemented `REPLACE(col, '"', '""')` in SELECT query.
+
+2. **Parquet corruption fix (v2.17.0):** The RFC 4180 `REPLACE` was applied to all
+   export formats, including Parquet — corrupting values that contained double-quotes.
+   Fix: added `pFormat` parameter to `buildQueryWithDateFormats`; `REPLACE` is now
+   applied only when `pFormat = 'CSV'`. Parquet exports pass column values unchanged.

+
+## Prerequisites
+
+- Oracle Database 23ai
+- `CT_MRDS.ENV_MANAGER` v3.1.0+
+- ADMIN user with EXECUTE privileges on CT_MRDS schema
+- Connection service: `ggmichalski_high`
+
+## Version Change
+
+| Package | Before | After |
+|---------|--------|-------|
+| `CT_MRDS.DATA_EXPORTER` | v2.14.0 | v2.17.0 |
+
+## Installation
+
+### Option 1: Master Script (Recommended)
+
+```powershell
+# Execute as ADMIN user for proper privilege management
+Get-Content "MARS_Packages/REL03/MARS-1005-PREHOOK/install_mars1005_prehook.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
+```
+
+Log file created automatically: `log/INSTALL_MARS_1005_PREHOOK_<PDB>_<timestamp>.log`
+
+### Option 2: Individual Scripts
+
+```powershell
+# Execute as ADMIN user
+Get-Content "MARS_Packages/REL03/MARS-1005-PREHOOK/00_MARS_1005_PREHOOK_install_DATA_EXPORTER.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
+```
+
+## Verification
+
+```sql
+-- Verify package version
+SELECT CT_MRDS.DATA_EXPORTER.GET_VERSION() FROM DUAL;
+-- Expected: 2.17.0
+
+-- Verify build info
+SELECT CT_MRDS.DATA_EXPORTER.GET_BUILD_INFO() FROM DUAL;
+
+-- Check for compilation errors
+SELECT * FROM ALL_ERRORS
+WHERE OWNER = 'CT_MRDS'
+  AND NAME = 'DATA_EXPORTER';
+
+-- Verify no untracked changes
+SELECT CT_MRDS.ENV_MANAGER.CHECK_PACKAGE_CHANGES('CT_MRDS', 'DATA_EXPORTER') FROM DUAL;
+-- Expected: OK
+```
+
+## Rollback
+
+```powershell
+# Execute as ADMIN user
+Get-Content "MARS_Packages/REL03/MARS-1005-PREHOOK/rollback_mars1005_prehook.sql" | sql "ADMIN/Cloudpass#34@ggmichalski_high"
+```
+
+Rollback restores `CT_MRDS.DATA_EXPORTER` to v2.14.0 (re-enables `escape=true`).
+
+## Testing
+
+After installation, verify the Parquet and CSV export paths:
+
+**CSV path (ODS):** Export a table, then SELECT from the corresponding ODS external
+table. Values with embedded double-quotes should appear as single `"` characters
+and not trigger `ORA-30653`.
+
+**Parquet path (ARCHIVE):** Export a table containing values with embedded
+double-quotes to the ARCHIVE bucket area. Download the Parquet file and confirm
+the value is stored verbatim (no extra quotes).
+
+## Expected Changes
+
+- `CT_MRDS.DATA_EXPORTER`: v2.14.0 → v2.17.0
+- No table structure changes
+- No configuration changes
+

+-- MARS-1005-PREHOOK INSTALL SCRIPT: Fix DATA_EXPORTER RFC 4180 Compliance
+-- ===================================================================
+-- Purpose: Pre-hook for MARS-1005 - Deploy updated DATA_EXPORTER (v2.17.0)
+--          that fixes RFC 4180 CSV compliance and Parquet format corruption.
+-- Background: DATA_EXPORTER v2.14.0 uses escape=true in DBMS_CLOUD.EXPORT_DATA,
+--             which produces backslash-escaped embedded quotes (\")
+--             instead of RFC 4180 doubling ("").
+--             v2.16.0 fixed CSV by applying REPLACE(col, '"', '""') in SELECT,
+--             but this corrupted Parquet exports containing double-quote values.
+--             v2.17.0 applies REPLACE only when pFormat = 'CSV', leaving
+--             Parquet exports unchanged.
+-- Author: Grzegorz Michalski
+-- Date: 2026-03-10
+
+-- Dynamic spool file generation (using SYS_CONTEXT - no DBA privileges required)
+-- Log files are automatically created in log/ subdirectory
+-- IMPORTANT: Ensure log/ directory exists before SPOOL (use host mkdir)

+PROMPT Problem: DATA_EXPORTER v2.14.0 uses escape=true which produces \"-escaped
+PROMPT          quotes instead of RFC 4180 doubling "". v2.16.0 fixed CSV but
