  If > 2 hops:
  Redirect 1: www.example.com -> example.com
  Redirect 2: http -> https
  Solution: Combine to 1 hop in .htaccess

IF: HTTP still accessible
THEN: Force HTTPS
  Add to .htaccess:
  RewriteCond %{HTTPS} off
  RewriteRule ^(.*)$ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

THEN: Simplify redirects
  Example:
  /old-page -> /blog/new-page -> /about (2 hops)
  Better: Direct /old-page -> /about (1 hop)

  Impact: Each extra hop = ~200ms delay

IF: External redirects > 3
THEN: Minimize external redirects
  These are slower due to DNS lookup
  Consider: Keep redirects on same domain

IF: Redirect to external domain
THEN: Verify necessity
  Example: Redirect to analytics = unnecessary
  Example: Redirect to CDN = necessary
```

---

  - Insufficient RAM for caching
  - Slow database server
  - Slow disk (HDD vs SSD)

  Fixes require investigation:
  - Profile database
  - Add caching
  - Upgrade to SSD
  - Optimize queries

- Processes: 156

**Remediation Capability:** POOR

**Intelligent Actions:**
```
IF: CPU usage > 80% consistently
THEN: Investigate CPU hog
  Top processes: top -bn1 | head -20
  Common causes: Slow plugin, inefficient code, too many workers
  Fix: Depends on root cause

IF: Load average > CPU count
THEN: System is over-utilized

       * hard nofile 65536
       * soft nproc 32768
       * hard nproc 32768

  Or in FPM pool:
  rlimit_files = 65536

IF: FD limit very low (< 256)

  MySQL query: SHOW PROCESSLIST;

  Long transactions block others:
  - Kill idle transaction: KILL {process_id};
  - Optimize slow query

IF: Lock wait time > 1 second
THEN: Database contention issue

## IMPLEMENTATION STRATEGY

### Phase 1: TIER 1 & 2 Integration
Create a remediation engine that:
1. Parses findings from temp files
2. Extracts specific values (numbers, names, versions)
3. Matches against thresholds
4. Generates specific, actionable recommendations
5. Provides actual commands to run

### Phase 2: Framework-Specific
Special handling for:
- WordPress (most detailed)
- Drupal (basic)
- Joomla (basic)
- Generic PHP (limited)

### Phase 3: Investigation-Guided
For diagnostic-only checks:
- Provide clear investigation steps
- Suggest tools to use
- Guide toward root cause analysis

## NEXT STEPS

1. Create `REMEDIATION_ENGINE.sh` with intelligent recommendation logic
2. Integrate into report generation
3. Test on multiple domains with different issues
4. Refine recommendations based on real-world testing
