📊 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

📋 NEXT STEPS

What would you like to do?

1. Start implementing - Which phase/category should we build first?
2. Refine the analysis - Any checks to add/remove/modify?
3. Build the framework - Create the remediation engine architecture?
4. Test on a domain - Prototype implementation on pickledperil.com?
5. Create a timeline - Detailed project plan for full implementation?
