Rails Engine Migration Plan - Review 1

Date: November 20, 2025 Status: COMPLETE Recommendation: Fix critical issues (P0) before implementation

---

📋 Review Overview

This review analyzes the Rails Engine migration plans in planning_notes/rails-engine-migration-json/ and identifies critical issues that must be addressed before implementation begins.

Overall Assessment: MOSTLY SOLID - REQUIRES CORRECTIONS

The migration plan is well-structured and technically sound, but several critical discrepancies between the plan's assumptions and the actual codebase structure were discovered.

🚨 Critical Findings

Blockers (Must Fix Before Phase 1)

1. Ink File Structure Mismatch

   • Plan assumes .ink.json files
   • Codebase uses .json files
   • Only 3 of 30 NPCs have compiled scripts
   • Impact: Phase 3 file reorganization will fail

2. Missing Ink Compilation

   • No documented compilation process
   • No tooling for compiling .ink → .json
   • Impact: NPC scripts won't work

3. Shared NPC Schema Issue

   • Schema forces 1:1 scenario-NPC relationship
   • Codebase has many-to-many usage
   • Impact: Seed script will fail or duplicate data

Total Fix Time: ~10 hours (1.25 days)

---

✅ Strengths of Current Plan

1. JSON-Centric Approach - Excellent fit for game state
2. Minimal Client Changes - <5% code change required
3. Hacktivity Compatibility - Thoroughly validated
4. Phased Implementation - Clear milestones
5. Comprehensive Documentation - 8 detailed guides
6. Security - CSP nonces, Pundit authorization

---

📊 Risk Assessment

Without Fixes:

• ❌ Implementation will fail at Phase 3
• ❌ Seed script will fail at Phase 5
• ❌ NPCs won't function (runtime errors)
• ❌ Minigame state will be lost
• ❌ Rework required: 3-5 days

With Fixes:

• ✅ Clean implementation
• ✅ No data loss
• ✅ No runtime errors
• ✅ Matches codebase reality

Recommendation: Fix P0 issues (10 hours) to save 3-5 days of rework

🎯 Action Plan

Week 0: Pre-Implementation Fixes (1.5-2 days)

Priority 0 (Blockers):

1. ✅ Fix Ink file structure handling - 2 hours
2. ✅ Add Ink compilation pipeline - 4 hours
3. ✅ Fix NPC schema for shared scripts - 4 hours

Priority 1 (Quality): 4. ✅ Extend player_state schema - 1 hour 5. ✅ Clarify room asset loading - 2 hours 6. ✅ Add JSON validation to ERB - 0.5 hours

Output: Updated planning documents ready for Phase 1

---

During Implementation

Phases 1-6: Write documentation (P3) Phase 10: Add tests (P4) Post-Launch: Add enhancements (P2)

---

📝 Files Requiring Updates

Planning Documents to Update:

1. 02_IMPLEMENTATION_PLAN.md

   • Add Phase 2.5: Ink compilation
   • Update Phase 3: File movement commands
   • Update Phase 4: Database migrations
   • Update Phase 5: ScenarioLoader code

2. 03_DATABASE_SCHEMA.md

   • Update NPC schema (shared registry)
   • Add join table documentation
   • Extend player_state structure

3. 01_ARCHITECTURE.md

   • Clarify room asset serving
   • Update model examples
   • Add minigame state tracking

---

🔧 Implementation Checklist

Before Starting Phase 1:

• Read 00_EXECUTIVE_SUMMARY.md
• Read 01_CRITICAL_ISSUES.md
• Read 05_RECOMMENDATIONS.md
• Update 02_IMPLEMENTATION_PLAN.md with fixes
• Update 03_DATABASE_SCHEMA.md with new schema
• Create scripts/compile_ink.sh
• Test Ink compilation on 2-3 scenarios
• Verify all .ink files compile successfully
• Commit updated planning documents

After Fixes Complete:

• Re-review updated plans
• Validate fixes with team
• Begin Phase 1 with confidence

---

📈 Timeline Impact

Scenario	Timeline	Outcome
Without fixes	12 weeks + 3-5 days rework	Failed implementation, rework required
With fixes	+1.5 days prep + 12 weeks	Clean implementation, no rework

Net Impact: +1.5 days upfront, saves 3-5 days of rework Overall Timeline: Still within 12-14 week estimate

---

🎓 Key Learnings

1. Always validate assumptions - Plan assumptions must match codebase reality
2. Check file conventions - Naming patterns matter (.json vs .ink.json)
3. Schema must match usage - Database relationships should reflect actual data patterns
4. Compilation is critical - Document tooling for generated files
5. State must be complete - Track all game state, not just core mechanics
