Date: 2026-01-31
Auditor: Claude (Opus 4.5)
Scope: All 18 documents in CODITECT-cloudflare-r2-gcs
Status: ⚠️ ISSUES FOUND
Executive Summary
| Category | Count | Status |
|---|---|---|
| Documents Audited | 18 | ✅ |
| Critical Issues | 1 | 🔴 |
| Minor Issues | 3 | 🟡 |
| v2.0 Consistency | 9 docs | ✅ Consistent |
| v1.0 Legacy (Expected Different) | 5 docs | ✅ As Expected |
Overall Assessment: The v2.0 architecture documentation is internally consistent. One critical issue (document duplication) requires immediate fix.
🔴 Critical Issues
Issue #1: Document Duplication in UNIFIED-PERSISTENT-ARCHITECTURE.md
Location: CODITECT-UNIFIED-PERSISTENT-ARCHITECTURE.md
Line: 472 onwards
Severity: CRITICAL
Problem: The entire document content is duplicated starting at line 472. The content from line 472-491 is:
# CODITECT Development Studio - Unified Persistent Architecture v2.0
**Version:** 2.0.0
**Date:** 2026-01-31
**Status:** Draft
**Changes:** Single persistent sandbox, multi-LLM coordination, GCS primary storage, SQLite session databases
This is an exact repeat of lines 1-20.
Impact:
- Document is ~2x larger than necessary (66KB vs expected ~33KB)
- Confusing for readers
- Potential for inconsistency if one section is updated but not the duplicate
Fix Required: Remove duplicate content from line 472 to end (lines 472-945 approximately).
🟡 Minor Issues
Issue #2: Inconsistent Document Status Fields
Documents Affected: Multiple
Severity: MINOR
| Document | Status Field | Inconsistency |
|---|---|---|
ADR-XXX | "Accepted" | ✅ Correct - ADR should be Accepted |
UNIFIED-PERSISTENT-ARCHITECTURE | "Draft" | 🟡 Should be "Complete" or "Approved" |
SDD-v2 | "Draft" | 🟡 Should be "Complete" |
TDD-v2 | "Draft" | 🟡 Should be "Complete" |
ARDS-v2 | "Draft" | 🟡 Should be "Complete" |
Recommendation: Update status fields to reflect actual document maturity.
Issue #3: Slight Cost Discrepancy in Economic Models
Documents: CODITECT-REVISED-ECONOMIC-MODEL.md vs EXECUTIVE-SUMMARY-v2.0.md
Severity: MINOR
| Metric | REVISED-ECONOMIC-MODEL | EXECUTIVE-SUMMARY | Variance |
|---|---|---|---|
| v2.0 @ 1K users | $6,557 | $6,500 | +$57 (+0.9%) |
| Cost per user | $6.557 | $6.50 | +$0.057 |
Root Cause: REVISED-ECONOMIC-MODEL includes exact calculation ($6,557), while EXECUTIVE-SUMMARY rounds to $6,500 for presentation.
Recommendation: Standardize on rounded figures ($6,500) for consistency across all executive-facing documents.
Issue #4: Database Size Estimates Slightly Inconsistent
Documents: Various v2.0 docs
Severity: MINOR
| Database | UNIFIED-ARCHITECTURE | SDD-v2 | Variance |
|---|---|---|---|
| sessions.db | 500MB | 500MB | ✅ Match |
| messages.db | 2GB | 2GB | ✅ Match |
| artifacts.db | 1GB | 1GB | ✅ Match |
| parsed_sessions.db | 5GB | 5GB | ✅ Match |
| agent_metrics.db | 100MB | 100MB | ✅ Match |
| workspace_idx.db | 200MB | 200MB | ✅ Match |
| Total | ~9GB | ~9GB | ✅ Match |
Note: All database sizes are actually CONSISTENT. This is a false positive - documenting for completeness.
