# Remediation Master Index
## Complete Analysis of Website Slowness Diagnostics Coverage

**Date**: February 26, 2026
**Status**: Comprehensive remediation mapping complete

---

## 📊 THREE-DOCUMENT ROADMAP

### Document 1: REMEDIATION_MAPPING.md (1384 lines)
**Purpose**: Baseline analysis of all 41 current analysis functions

**Content**:
- Tier 1 (Highly Reliable): 16 checks with specific remediation
- Tier 2 (Moderately Reliable): 16 checks with targeted guidance  
- Tier 3 (Diagnostic Only): 9 checks for investigation

**Current Coverage**: 32 out of 41 checks (78%)

**Examples**:
- Missing Critical Indexes → Add index to wp_postmeta(meta_key)
- Autoloaded Options → wp option list --autoload=yes
- Disk Space → Clean backups, move old files
- PHP Memory → Increase memory_limit to 256M-512M

---

### Document 2: REMEDIATION_GAPS_ANALYSIS.md (810 lines)
**Purpose**: Identify missing checks from original plan

**Content**:
- 15 additional actionable opportunities
- Categorized by difficulty (Easy/Medium/Hard)
- Categorized by impact (HIGH/MEDIUM/LOW)

**Examples**:
1. **Missing Critical Indexes** - Detect wp_posts.post_type without index
2. **Database/Memory Correlation** - Warn if 500MB DB on 2GB server
3. **Memory Allocation vs Recommended** - WordPress needs 256M, site has 128M
4. **PHP Version Compatibility** - PHP 7.2 EOL, recommend 8.1+
5. **PHP-FPM Optimization** - Tune max_children based on RAM

**Priority Breakdown**:
- TIER A (Add First): 6 checks - Easy, High Impact ✅
- TIER B (Add Second): 5 checks - Medium complexity
- TIER C (Add Later): 4 checks - Complex or Lower Impact
