  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]

  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
```

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

  Or in FPM pool:
  rlimit_files = 65536

IF: FD limit very low (< 256)

- Orphaned: 2 (from deleted plugin)

**Remediation Capability:** MODERATE

**Intelligent Actions:**
```
IF: Orphaned plugin tables found
THEN: Clean them up
  Command: DROP TABLE {table_name};

  List orphaned tables:
  Select those not matching active plugins

IF: Plugin table very large (> 200MB)
THEN: Check if it needs cleanup
  Example: woocommerce_sessions
  Action: Cleanup old sessions

IF: Unknown plugin table
THEN: Identify plugin owner
  Table name hints: wc_ = WooCommerce, aios_ = All in One SEO, etc.

## 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
