📋 Issue Type

🔒 Security Documentation

🎯 Objective

Enhance FUTURE_SECURITY_ARCHITECTURE.md with missing structural elements: Architecture Documentation Map, ISMS Policy Alignment, per-enhancement control mappings, budget/resource planning, and Document Control footer with compliance badges.

⚠️ Scope: This issue ONLY modifies FUTURE_SECURITY_ARCHITECTURE.md. No other files are touched. This enables parallel execution with other per-document issues.

📌 Supersedes: #380 (closed — restructured to avoid merge conflicts)

📊 Current State Analysis

File: FUTURE_SECURITY_ARCHITECTURE.md (696 lines, ~30KB)
Reference: CIA (~800 lines, ~42KB) · Black Trigram (~1,500 lines, ~74KB)

✅ Already has: Centered Hack23 logo, badge-style metadata, subtitle, 6 Mermaid diagrams, roadmap phases

🔍 Missing Elements

🚀 Required Changes

1️⃣ Add Architecture Documentation Map

Add ## 📚 Architecture Documentation Map table with all 15 docs, current doc bolded.

2️⃣ Add ISMS Policy Alignment

Add ## 🔐 ISMS Policy Alignment section:

• 🔗 Link to Information Security Policy, Secure Development Policy
• 📊 Security Control Implementation Status table

3️⃣ Expand Control Mappings

For each future enhancement, add specific control mappings:

• 🏛️ ISO 27001:2022 Annex A control references
• 🔄 NIST CSF 2.0 function mappings (Govern, Identify, Protect, Detect, Respond, Recover)
• 🛡️ CIS Controls v8.1 safeguard references

4️⃣ Add Budget & Resource Planning

Add ## 💰 Security Investment & Budget:

• 📊 Per-phase cost estimates (even if approximate)
• 🧑‍💻 Resource requirements
• 📈 ROI projections
