-## [3.42.0] - 2026-01-07 "The Operator"
+## [3.42.10] - 2026-01-08 "Code Quality"
 
-### Added - 🐧 Systemd Integration & Prometheus Metrics
+### Fixed - Code Quality Issues
+- Removed deprecated `io/ioutil` usage (replaced with `os`)
+- Fixed `os.DirEntry.ModTime()` → `file.Info().ModTime()`
+- Removed unused fields and variables
+- Fixed ineffective assignments in TUI code
+- Fixed error strings (no capitalization, no trailing punctuation)
+
+## [3.42.9] - 2026-01-08 "Diagnose Timeout Fix"
+
+### Fixed - diagnose.go Timeout Bugs
+
+**More short timeouts that caused large archive failures:**
+
+- `diagnoseClusterArchive()`: tar listing 60s → **5 minutes**
+- `verifyWithPgRestore()`: pg_restore --list 60s → **5 minutes**
+- `DiagnoseClusterDumps()`: archive listing 120s → **10 minutes**
+
+**Impact:** These timeouts caused "context deadline exceeded" errors when
+diagnosing multi-GB backup archives, preventing TUI restore from even starting.
+
+## [3.42.8] - 2026-01-08 "TUI Timeout Fix"
+
+### Fixed - TUI Timeout Bugs Causing Backup/Restore Failures
+
+**ROOT CAUSE of 2-3 month TUI backup/restore failures identified and fixed:**
+
+#### Critical Timeout Fixes:
+- **restore_preview.go**: Safety check timeout increased from 60s → **10 minutes**
+  - Large archives (>1GB) take 2+ minutes to diagnose
+  - Users saw "context deadline exceeded" before backup even started
+- **dbselector.go**: Database listing timeout increased from 15s → **60 seconds**
+  - Busy PostgreSQL servers need more time to respond
+- **status.go**: Status check timeout increased from 10s → **30 seconds**
+  - SSL negotiation and slow networks caused failures
+
+#### Stability Improvements:
+- **Panic recovery** added to parallel goroutines in:
+  - `backup/engine.go:BackupCluster()` - cluster backup workers
+  - `restore/engine.go:RestoreCluster()` - cluster restore workers
+  - Prevents single database panic from crashing entire operation
+
+#### Bug Fix:
+- **restore/engine.go**: Fixed variable shadowing `err` → `cmdErr` for exit code detection
+
+## [3.42.7] - 2026-01-08 "Context Killer Complete"
+
+### Fixed - Additional Deadlock Bugs in Restore & Engine
+
+**All remaining cmd.Wait() deadlock bugs fixed across the codebase:**
+
+#### internal/restore/engine.go:
+- `executeRestoreWithDecompression()` - gunzip/pigz pipeline restore
+- `extractArchive()` - tar extraction for cluster restore
+- `restoreGlobals()` - pg_dumpall globals restore
+
+#### internal/backup/engine.go:
+- `createArchive()` - tar/pigz archive creation pipeline
+
+#### internal/engine/mysqldump.go:
+- `Backup()` - mysqldump backup operation
+- `BackupToWriter()` - streaming mysqldump to writer
+
+**All 6 functions now use proper channel-based context handling with Process.Kill().**
+
+## [3.42.6] - 2026-01-08 "Deadlock Killer"
+
+### Fixed - Backup Command Context Handling
+
+**Critical Bug: pg_dump/mysqldump could hang forever on context cancellation**
+
+The `executeCommand`, `executeCommandWithProgress`, `executeMySQLWithProgressAndCompression`, 
+and `executeMySQLWithCompression` functions had a race condition where:
+
+1. A goroutine was spawned to read stderr
+2. `cmd.Wait()` was called directly
+3. If context was cancelled, the process was NOT killed
+4. The goroutine could hang forever waiting for stderr
+
+**Fix**: All backup execution functions now use proper channel-based context handling:
+```go
+// Wait for command with context handling
+cmdDone := make(chan error, 1)
+go func() {
+    cmdDone <- cmd.Wait()
+}()
+
+select {
+case cmdErr = <-cmdDone:
+    // Command completed
+case <-ctx.Done():
+    // Context cancelled - kill process
+    cmd.Process.Kill()
+    <-cmdDone
+    cmdErr = ctx.Err()
+}
+```
+
+**Affected Functions:**
+- `executeCommand()` - pg_dump for cluster backup
+- `executeCommandWithProgress()` - pg_dump for single backup with progress
+- `executeMySQLWithProgressAndCompression()` - mysqldump pipeline
+- `executeMySQLWithCompression()` - mysqldump pipeline
+
+**This fixes:** Backup operations hanging indefinitely when cancelled or timing out.
+
+## [3.42.5] - 2026-01-08 "False Positive Fix"
+
+### Fixed - Encryption Detection Bug
+
+**IsBackupEncrypted False Positive:**
+- **BUG FIX**: `IsBackupEncrypted()` returned `true` for ALL files, blocking normal restores
+- Root cause: Fallback logic checked if first 12 bytes (nonce size) could be read - always true
+- Fix: Now properly detects known unencrypted formats by magic bytes:
+  - Gzip: `1f 8b`
+  - PostgreSQL custom: `PGDMP`
+  - Plain SQL: starts with `--`, `SET`, `CREATE`
+- Returns `false` if no metadata present and format is recognized as unencrypted
+- Affected file: `internal/backup/encryption.go`
+
+## [3.42.4] - 2026-01-08 "The Long Haul"
+
+### Fixed - Critical Restore Timeout Bug
+
+**Removed Arbitrary Timeouts from Backup/Restore Operations:**
+- **CRITICAL FIX**: Removed 4-hour timeout that was killing large database restores
+- PostgreSQL cluster restores of 69GB+ databases no longer fail with "context deadline exceeded"
+- All backup/restore operations now use `context.WithCancel` instead of `context.WithTimeout`
+- Operations run until completion or manual cancellation (Ctrl+C)
+
+**Affected Files:**
+- `internal/tui/restore_exec.go`: Changed from 4-hour timeout to context.WithCancel
+- `internal/tui/backup_exec.go`: Changed from 4-hour timeout to context.WithCancel  
+- `internal/backup/engine.go`: Removed per-database timeout in cluster backup
+- `cmd/restore.go`: CLI restore commands use context.WithCancel
+
+**exec.Command Context Audit:**
+- Fixed `exec.Command` without Context in `internal/restore/engine.go:730`
+- Added proper context handling to all external command calls
+- Added timeouts only for quick diagnostic/version checks (not restore path):
+  - `restore/version_check.go`: 30s timeout for pg_restore --version check only
+  - `restore/error_report.go`: 10s timeout for tool version detection
+  - `restore/diagnose.go`: 60s timeout for diagnostic functions
+  - `pitr/binlog.go`: 10s timeout for mysqlbinlog --version check
+  - `cleanup/processes.go`: 5s timeout for process listing
+  - `auth/helper.go`: 30s timeout for auth helper commands
+
+**Verification:**
+- 54 total `exec.CommandContext` calls verified in backup/restore/pitr path
+- 0 `exec.Command` without Context in critical restore path
+- All 14 PostgreSQL exec calls use CommandContext (pg_dump, pg_restore, psql)
+- All 15 MySQL/MariaDB exec calls use CommandContext (mysqldump, mysql, mysqlbinlog)
+- All 14 test packages pass
+
+### Technical Details
+- Large Object (BLOB/BYTEA) restores are particularly affected by timeouts
+- 69GB database with large objects can take 5+ hours to restore
+- Previous 4-hour hard timeout was causing consistent failures
+- Now: No timeout - runs until complete or user cancels
+
+## [3.42.1] - 2026-01-07 "Resistance is Futile"
+
+### Added - Content-Defined Chunking Deduplication
+
+**Deduplication Engine:**
+- New `dbbackup dedup` command family for space-efficient backups
+- Gear hash content-defined chunking (CDC) with 92%+ overlap on shifted data
+- SHA-256 content-addressed storage - chunks stored by hash
+- AES-256-GCM per-chunk encryption (optional, via `--encrypt`)
+- Gzip compression enabled by default
+- SQLite index for fast chunk lookups
+- JSON manifests track chunks per backup with full verification
+
+**Dedup Commands:**
+```bash
+dbbackup dedup backup <file>              # Create deduplicated backup
+dbbackup dedup backup <file> --encrypt    # With encryption
+dbbackup dedup restore <id> <output>      # Restore from manifest
+dbbackup dedup list                       # List all backups
+dbbackup dedup stats                      # Show deduplication statistics
+dbbackup dedup delete <id>                # Delete a backup manifest
+dbbackup dedup gc                         # Garbage collect unreferenced chunks
+```
+
+**Storage Structure:**
+```
+<backup-dir>/dedup/
+  chunks/           # Content-addressed chunk files (sharded by hash prefix)
+  manifests/        # JSON manifest per backup
+  chunks.db         # SQLite index for fast lookups
+```
+
+**Test Results:**
+- First 5MB backup: 448 chunks, 5MB stored
+- Modified 5MB file: 448 chunks, only 1 NEW chunk (1.6KB), 100% dedup ratio
+- Restore with SHA-256 verification
+
+### Added - Documentation Updates
+- Prometheus alerting rules added to SYSTEMD.md
+- Catalog sync instructions for existing backups
+
+## [3.41.1] - 2026-01-07
+
+### Fixed
+- Enabled CGO for Linux builds (required for SQLite catalog)
+
+## [3.41.0] - 2026-01-07 "The Operator"
+
+### Added - Systemd Integration & Prometheus Metrics
 
 **Embedded Systemd Installer:**
 - New `dbbackup install` command installs as systemd service/timer

+# Emoticon Removal Plan for Python Code
+
+## ⚠️ CRITICAL: Code Must Remain Functional After Removal
+
+This document outlines a **safe, systematic approach** to removing emoticons from Python code without breaking functionality.
+
+---
+
+## 1. Identification Phase
+
+### 1.1 Where Emoticons CAN Safely Exist (Safe to Remove)
+| Location | Risk Level | Action |
+|----------|------------|--------|
+| Comments (`# 🎉 Success!`) | ✅ SAFE | Remove or replace with text |
+| Docstrings (`"""📌 Note:..."""`) | ✅ SAFE | Remove or replace with text |
+| Print statements for decoration (`print("✅ Done!")`) | ⚠️ LOW | Replace with ASCII or text |
+| Logging messages (`logger.info("🔥 Starting...")`) | ⚠️ LOW | Replace with text equivalent |
+
+### 1.2 Where Emoticons are DANGEROUS to Remove
+| Location | Risk Level | Action |
+|----------|------------|--------|
+| String literals used in logic | 🚨 HIGH | **DO NOT REMOVE** without analysis |
+| Dictionary keys (`{"🔑": value}`) | 🚨 CRITICAL | **NEVER REMOVE** - breaks code |
+| Regex patterns | 🚨 CRITICAL | **NEVER REMOVE** - breaks matching |
+| String comparisons (`if x == "✅"`) | 🚨 CRITICAL | Requires refactoring, not just removal |
+| Database/API payloads | 🚨 CRITICAL | May break external systems |
+| File content markers | 🚨 HIGH | May break parsing logic |
+
+---
+
+## 2. Pre-Removal Checklist
+
+### 2.1 Before ANY Changes
+- [ ] **Full backup** of the codebase
+- [ ] **Run all tests** and record baseline results
+- [ ] **Document all emoticon locations** with grep/search
+- [ ] **Identify emoticon usage patterns** (decorative vs. functional)
+
+### 2.2 Discovery Commands
+```bash
+# Find all files with emoticons (Unicode range for common emojis)
+grep -rn --include="*.py" -P '[\x{1F300}-\x{1F9FF}]' .
+
+# Find emoticons in strings
+grep -rn --include="*.py" -E '["'"'"'][^"'"'"']*[\x{1F300}-\x{1F9FF}]' .
+
+# List unique emoticons used
+grep -oP '[\x{1F300}-\x{1F9FF}]' *.py | sort -u
+```
+
+---
+
+## 3. Replacement Strategy
+
+### 3.1 Semantic Replacement Table
+| Emoticon | Text Replacement | Context |
+|----------|------------------|---------|
+| ✅ | `[OK]` or `[SUCCESS]` | Status indicators |
+| ❌ | `[FAIL]` or `[ERROR]` | Error indicators |
+| ⚠️ | `[WARNING]` | Warning messages |
+| 🔥 | `[HOT]` or `` (remove) | Decorative |
+| 🎉 | `[DONE]` or `` (remove) | Celebration/completion |
+| 📌 | `[NOTE]` | Notes/pinned items |
+| 🚀 | `[START]` or `` (remove) | Launch/start indicators |
+| 💾 | `[SAVE]` | Save operations |
+| 🔑 | `[KEY]` | Key/authentication |
+| 📁 | `[FILE]` | File operations |
+| 🔍 | `[SEARCH]` | Search operations |
+| ⏳ | `[WAIT]` or `[LOADING]` | Progress indicators |
+| 🛑 | `[STOP]` | Stop/halt indicators |
+| ℹ️ | `[INFO]` | Information |
+| 🐛 | `[BUG]` or `[DEBUG]` | Debug messages |
+
+### 3.2 Context-Aware Replacement Rules
+
+```
+RULE 1: Comments
+  - Remove emoticon entirely OR replace with text
+  - Example: `# 🎉 Feature complete` → `# Feature complete`
+
+RULE 2: User-facing strings (print/logging)
+  - Replace with semantic text equivalent
+  - Example: `print("✅ Backup complete")` → `print("[OK] Backup complete")`
+
+RULE 3: Functional strings (DANGER ZONE)
+  - DO NOT auto-replace
+  - Requires manual code refactoring
+  - Example: `status = "✅"` → Refactor to `status = "success"` AND update all comparisons
+```
+
+---
+
+## 4. Safe Removal Process
+
+### Step 1: Audit
+```python
+# Python script to audit emoticon usage
+import re
+import ast
+
+EMOJI_PATTERN = re.compile(
+    "["
+    "\U0001F300-\U0001F9FF"  # Symbols & Pictographs
+    "\U00002600-\U000026FF"  # Misc symbols
+    "\U00002700-\U000027BF"  # Dingbats
+    "\U0001F600-\U0001F64F"  # Emoticons
+    "]+"
+)
+
+def audit_file(filepath):
+    with open(filepath, 'r', encoding='utf-8') as f:
+        content = f.read()
+    
+    # Parse AST to understand context
+    tree = ast.parse(content)
+    
+    findings = []
+    for lineno, line in enumerate(content.split('\n'), 1):
+        matches = EMOJI_PATTERN.findall(line)
+        if matches:
+            # Determine context (comment, string, etc.)
+            context = classify_context(line, matches)
+            findings.append({
+                'line': lineno,
+                'content': line.strip(),
+                'emojis': matches,
+                'context': context,
+                'risk': assess_risk(context)
+            })
+    return findings
+
+def classify_context(line, matches):
+    stripped = line.strip()
+    if stripped.startswith('#'):
+        return 'COMMENT'
+    if 'print(' in line or 'logging.' in line or 'logger.' in line:
+        return 'OUTPUT'
+    if '==' in line or '!=' in line:
+        return 'COMPARISON'
+    if re.search(r'["\'][^"\']*$', line.split('#')[0]):
+        return 'STRING_LITERAL'
+    return 'UNKNOWN'
+
+def assess_risk(context):
+    risk_map = {
+        'COMMENT': 'LOW',
+        'OUTPUT': 'LOW',
+        'COMPARISON': 'CRITICAL',
+        'STRING_LITERAL': 'HIGH',
+        'UNKNOWN': 'HIGH'
+    }
+    return risk_map.get(context, 'HIGH')
+```
+
+### Step 2: Generate Change Plan
+```python
+def generate_change_plan(findings):
+    plan = {'safe': [], 'review_required': [], 'do_not_touch': []}
+    
+    for finding in findings:
+        if finding['risk'] == 'LOW':
+            plan['safe'].append(finding)
+        elif finding['risk'] == 'HIGH':
+            plan['review_required'].append(finding)
+        else:  # CRITICAL
+            plan['do_not_touch'].append(finding)
+    
+    return plan
+```
+
+### Step 3: Apply Changes (SAFE items only)
+```python
+def apply_safe_replacements(filepath, replacements):
+    # Create backup first!
+    import shutil
+    shutil.copy(filepath, filepath + '.backup')
+    
+    with open(filepath, 'r', encoding='utf-8') as f:
+        content = f.read()
+    
+    for old, new in replacements:
+        content = content.replace(old, new)
+    
+    with open(filepath, 'w', encoding='utf-8') as f:
+        f.write(content)
+```
+
+### Step 4: Validate
+```bash
+# After each file change:
+python -m py_compile <modified_file.py>  # Syntax check
+pytest <related_tests>                     # Run tests
+```
+
+---
+
+## 5. Validation Checklist
+
+### After EACH File Modification
+- [ ] File compiles without syntax errors (`python -m py_compile file.py`)
+- [ ] All imports still work
+- [ ] Related unit tests pass
+- [ ] Integration tests pass
+- [ ] Manual smoke test if applicable
+
+### After ALL Modifications
+- [ ] Full test suite passes
+- [ ] Application starts correctly
+- [ ] Key functionality verified manually
+- [ ] No new warnings in logs
+- [ ] Compare output with baseline
+
+---
+
+## 6. Rollback Plan
+
+### If Something Breaks
+1. **Immediate**: Restore from `.backup` files
+2. **Git**: `git checkout -- <file>` or `git stash pop`
+3. **Full rollback**: Restore from pre-change backup
+
+### Keep Until Verified
+```bash
+# Backup storage structure
+backups/
+├── pre_emoticon_removal/
+│   ├── timestamp.tar.gz
+│   └── git_commit_hash.txt
+└── individual_files/
+    ├── file1.py.backup
+    └── file2.py.backup
+```
+
+---
+
+## 7. Implementation Order
+
+1. **Phase 1**: Comments only (LOWEST risk)
+2. **Phase 2**: Docstrings (LOW risk)
+3. **Phase 3**: Print/logging statements (LOW-MEDIUM risk)
+4. **Phase 4**: Manual review items (HIGH risk) - one by one
+5. **Phase 5**: NEVER touch CRITICAL items without full refactoring
+
+---
+
+## 8. Example Workflow
+
+```bash
+# 1. Create full backup
+git stash && git checkout -b emoticon-removal
+
+# 2. Run audit script
+python emoticon_audit.py > audit_report.json
+
+# 3. Review audit report
+cat audit_report.json | jq '.do_not_touch'  # Check critical items
+
+# 4. Apply safe changes only
+python apply_safe_changes.py --dry-run  # Preview first!
+python apply_safe_changes.py            # Apply
+
+# 5. Validate after each change
+python -m pytest tests/
+
+# 6. Commit incrementally
+git add -p  # Review each change
+git commit -m "Remove emoticons from comments in module X"
+```
+
+---
+
+## 9. DO NOT DO
+
+❌ **Never** use global find-replace on emoticons  
+❌ **Never** remove emoticons from string comparisons without refactoring  
+❌ **Never** change multiple files without testing between changes  
+❌ **Never** assume an emoticon is decorative - verify context  
+❌ **Never** proceed if tests fail after a change  
+
+---
+
+## 10. Sign-Off Requirements
+
+Before merging emoticon removal changes:
+- [ ] All tests pass (100%)
+- [ ] Code review by second developer
+- [ ] Manual testing of affected features
+- [ ] Documented all CRITICAL items left unchanged (with justification)
+- [ ] Backup verified and accessible

+# v3.42.1 Release Notes
+
+## What's New in v3.42.1
+
+### Deduplication - Resistance is Futile
+
+Content-defined chunking deduplication for space-efficient backups. Like restic/borgbackup but with **native database dump support**.
+
+```bash
+# First backup: 5MB stored
+dbbackup dedup backup mydb.dump
+
+# Second backup (modified): only 1.6KB new data stored!
+# 100% deduplication ratio
+dbbackup dedup backup mydb_modified.dump
+```
+
+#### Features
+- **Gear Hash CDC** - Content-defined chunking with 92%+ overlap on shifted data
+- **SHA-256 Content-Addressed** - Chunks stored by hash, automatic deduplication
+- **AES-256-GCM Encryption** - Optional per-chunk encryption
+- **Gzip Compression** - Optional compression (enabled by default)
+- **SQLite Index** - Fast chunk lookups and statistics
+
+#### Commands
+```bash
+dbbackup dedup backup <file>              # Create deduplicated backup
+dbbackup dedup backup <file> --encrypt    # With AES-256-GCM encryption
+dbbackup dedup restore <id> <output>      # Restore from manifest
+dbbackup dedup list                       # List all backups
+dbbackup dedup stats                      # Show deduplication statistics
+dbbackup dedup delete <id>                # Delete a backup
+dbbackup dedup gc                         # Garbage collect unreferenced chunks
+```
+
+#### Storage Structure
+```
+<backup-dir>/dedup/
+  chunks/           # Content-addressed chunk files
+    ab/cdef1234...  # Sharded by first 2 chars of hash
+  manifests/        # JSON manifest per backup
+  chunks.db         # SQLite index
+```
+
+### Also Included (from v3.41.x)
+- **Systemd Integration** - One-command install with `dbbackup install`
+- **Prometheus Metrics** - HTTP exporter on port 9399
+- **Backup Catalog** - SQLite-based tracking of all backup operations
+- **Prometheus Alerting Rules** - Added to SYSTEMD.md documentation
+
+### Installation

+
+### Loading Alert Rules
+
+```bash
+# Test rules syntax
+promtool check rules /etc/prometheus/rules/dbbackup.yml
+
+# Reload Prometheus
+sudo systemctl reload prometheus
+# or via API:
+curl -X POST http://localhost:9090/-/reload
+```
+
+## Catalog Sync for Existing Backups
+
+If you have existing backups created before installing v3.41+, sync them to the catalog:
+
+```bash
+# Sync existing backups to catalog
+dbbackup catalog sync /path/to/backup/directory --allow-root
+
+# Verify catalog contents
+dbbackup catalog list --allow-root
+
+# Show statistics
+dbbackup catalog stats --allow-root
+```
