--- name: log-decision --- # Log Decision Skill ## Implement Meta-Ledger for Auditable Decision Tracking **Skill Name:** log-decision **Version:** 1.0 **Purpose:** Implement QoreLogic SOA Ledger for development decisions --- ## Usage ``` /log-decision [risk_grade] ``` Or invoke in conversation: > "Let's log this architecture decision to the meta-ledger..." --- ## What This Skill Does Implements QoreLogic's **SOA Ledger** principle for meta-governance: maintaining a Merkle-chained, cryptographically signed audit trail of all major development decisions. Enables traceability, accountability, and rollback capability. --- ## Skill Instructions When this skill is invoked: ### 1. Gather Decision Details Collect comprehensive information: **Required Fields:** - **decision_type:** Category from taxonomy below - **decision:** What was decided (concise) - **rationale:** Why this decision was made - **evidence:** Supporting data/citations - **approver:** Who approved (Lead Reviewer, User, etc.) - **risk_grade:** L1/L2/L3 classification **Optional Fields:** - **alternatives_considered:** What else was evaluated - **trade_offs:** What we're sacrificing - **reversibility:** Can this be undone? How easily? - **dependencies:** What depends on this decision - **timeline_impact:** How does this affect schedule ### 2. Classify Decision Type Use standardized taxonomy: | Decision Type | Description | Risk Grade | Examples | |---------------|-------------|------------|----------| | **ARCHITECTURE** | System design, component structure | L2/L3 | "Use SQLite not PostgreSQL" | | **SECURITY** | Cryptography, auth, key management | L3 | "Migrate to platform keystore" | | **SCOPE_CHANGE** | Add/remove features | L2/L3 | "Defer PyVeritas to Phase 3" | | **TECH_STACK** | Languages, frameworks, dependencies | L2 | "Add pytest-cov for coverage" | | **TIMELINE** | Schedule adjustments | L1/L2 | "Extend Week 2 by 3 days" | | **QUALITY_GATE** | Standards, thresholds, criteria | L2 | "Require 80% test coverage" | | **PROCESS** | Development workflow changes | L1/L2 | "Weekly drift audits every Friday" | | **VENDOR** | Third-party service selection | L2/L3 | "Use GitHub Actions for CI/CD" | | **DEPLOYMENT** | Infrastructure, hosting decisions | L3 | "Deploy to AWS Lambda" | | **BUDGET** | Resource allocation, costs | L2 | "Allocate 2 engineers full-time" | ### 3. Validate Risk Grade Ensure correct L1/L2/L3 classification: **L3 CRITICAL (Requires User Approval):** - Security/cryptographic changes - Data schema modifications - Authentication/authorization - Production deployment architecture - Budget >$10K - Timeline slips >2 weeks **L2 FUNCTIONAL (Requires Lead Reviewer Approval):** - Architecture changes - Tech stack additions - Scope changes - Quality gate definitions - Timeline slips 1-2 weeks - Budget $1K-$10K **L1 ROUTINE (Lead Reviewer Decision):** - Process improvements - Documentation updates - Minor timeline adjustments (<1 week) - Budget <$1K ### 4. Load Current Ledger State Read `docs/META_LEDGER.md` to get: - Last entry ID - Previous entry hash - Current chain status ### 5. Create New Entry Generate ledger entry: ```json { "entry_id": 5, "timestamp": "2025-12-24T16:00:00Z", "decision_type": "ARCHITECTURE", "decision": "Use SQLite for Phases 1-2, defer PostgreSQL until 100+ agent scale", "rationale": "KISS principle - no proven bottleneck yet. Database audit shows <100 TPS sufficient for pilot. SQLite simpler, zero ops overhead, suitable for single-node deployment.", "evidence": [ "Database audit: current load <10 TPS", "SQLite supports <100 TPS per documentation", "PostgreSQL adds deployment complexity without current benefit" ], "alternatives_considered": [ "PostgreSQL: Rejected - no proven scalability need", "MongoDB: Rejected - relational data better fit", "MySQL: Rejected - no advantages over SQLite for this scale" ], "trade_offs": { "accepting": "Single-writer limit (~100 TPS), migration cost if scale exceeds", "gaining": "Simplicity, zero-ops deployment, file-based backups" }, "approver": "Lead Reviewer", "risk_grade": "L2", "reversibility": "Medium - migration to PostgreSQL possible but requires schema export/import", "dependencies": [ "Database hardening plan (Week 2)", "Backup strategy (requires file-based approach)" ], "timeline_impact": "Saves 1 week setup time vs PostgreSQL deployment", "related_decisions": [3, 4], "previous_hash": "b4a1f2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1", "entry_hash": "c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6" } ``` ### 6. Calculate Hash Generate Merkle chain link: ```python import hashlib import json def calculate_entry_hash(entry, previous_hash): # Create canonical representation hash_payload = { "entry_id": entry["entry_id"], "timestamp": entry["timestamp"], "decision_type": entry["decision_type"], "decision": entry["decision"], "rationale": entry["rationale"], "approver": entry["approver"], "risk_grade": entry["risk_grade"], "previous_hash": previous_hash } # Sort keys for deterministic hashing canonical = json.dumps(hash_payload, sort_keys=True) # SHA-256 hash return hashlib.sha256(canonical.encode()).hexdigest() ``` ### 7. Append to Ledger Update `docs/META_LEDGER.md`: ```markdown ## Entry #5: SQLite vs PostgreSQL Decision **Type:** ARCHITECTURE (L2) **Date:** 2025-12-24 16:00:00 UTC **Approver:** Lead Reviewer ### Decision Use SQLite for Phases 1-2, defer PostgreSQL migration until 100+ agent scale proven necessary. ### Rationale KISS principle - no proven bottleneck. Database audit shows current load <10 TPS, SQLite supports <100 TPS. PostgreSQL adds deployment complexity without current benefit. ### Evidence - Database audit: current load <10 TPS - SQLite documentation: supports <100 TPS single-writer - PostgreSQL deployment: requires containerization, ops overhead ### Alternatives Considered 1. **PostgreSQL** - Rejected: No proven scalability need, adds complexity 2. **MongoDB** - Rejected: Relational data better fit for ledger structure 3. **MySQL** - Rejected: No advantages over SQLite at this scale ### Trade-offs **Accepting:** - Single-writer limit (~100 TPS) - Migration cost if scale exceeds assumptions **Gaining:** - Simplicity (zero-ops, file-based) - Faster setup (saves 1 week) - File-based backups (easier disaster recovery) ### Reversibility **Medium** - Migration to PostgreSQL possible via schema export/import. Estimated 1 week effort if needed. ### Dependencies - Database hardening plan (Week 2) - must use file-based backup strategy - Performance testing (Week 7) - validates TPS assumptions ### Timeline Impact Saves 1 week setup time vs PostgreSQL deployment in Week 1. ### Related Decisions - #3: Database backup strategy - #4: Multi-tenant isolation approach ### Hash Chain ``` Previous: b4a1f2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1 Current: c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6 ``` --- ``` ### 8. Validate Chain Integrity After appending, verify: ```python def validate_ledger_integrity(ledger_file): """Verify entire Merkle chain integrity""" entries = load_ledger_entries(ledger_file) previous_hash = "0" * 64 # Genesis hash for entry in entries: # Recalculate hash expected_hash = calculate_entry_hash(entry, previous_hash) if entry["entry_hash"] != expected_hash: return False, f"Chain broken at entry {entry['entry_id']}" previous_hash = entry["entry_hash"] return True, "Chain integrity verified" ``` ### 9. Check L3 Approval Requirements If risk_grade is L3: ```markdown ## ⚠️ L3 APPROVAL REQUIRED This decision requires explicit user approval before implementation. **Decision:** {decision} **Risk Grade:** L3 CRITICAL **Impact:** {impact description} **Approval Status:** PENDING **Approval Deadline:** {24 hours from now} **To approve, user must:** 1. Review decision, rationale, and evidence 2. Confirm understanding of trade-offs 3. Provide written approval: "APPROVED: Entry #{entry_id}" 4. Sign approval (optional but recommended) **Until approved:** - Implementation blocked - Related work can proceed if not dependent - Decision remains in CONDITIONAL status ``` --- ## Examples ### Example 1: Architecture Decision (L2) **Command:** ``` /log-decision ARCHITECTURE "Use SQLite for Phases 1-2" "KISS - no proven bottleneck" L2 ``` **Output:** ```markdown ✅ Meta-Ledger Updated: Entry #5 **Decision Type:** ARCHITECTURE (L2) **Decision:** Use SQLite for Phases 1-2 **Approver:** Lead Reviewer **Status:** APPROVED (L2 - Lead Reviewer authority) **Hash Chain:** ✅ Integrity verified **File Updated:** docs/META_LEDGER.md **Next Steps:** - Implementation can proceed - No user approval required (L2) ``` ### Example 2: Security Decision (L3) **Command:** ``` /log-decision SECURITY "Migrate passphrase to platform keystore" "Fix CRITICAL vulnerability" L3 ``` **Output:** ```markdown ⚠️ Meta-Ledger Updated: Entry #6 (PENDING APPROVAL) **Decision Type:** SECURITY (L3 CRITICAL) **Decision:** Migrate passphrase storage to platform keystore **Impact:** Fixes CRITICAL security vulnerability (plaintext master passphrase) **Status:** CONDITIONAL - Awaiting user approval **Approval Required By:** 2025-12-25 16:00:00 UTC (24 hours) **Rationale:** Current plaintext storage at ~/.qorelogic/security/identity.secret creates single point of compromise. Platform keystore (Windows Credential Manager, macOS Keychain, Linux Secret Service) provides OS-level encryption and access control. **Trade-offs:** - **Accepting:** Platform dependency, different implementation per OS - **Gaining:** Hardware-backed encryption, audit trail, no plaintext secrets **Reversibility:** Low - migration one-way, manual keystore deletion needed to rollback **User Action Required:** Please review and respond with: - "APPROVED: Entry #6" to proceed with implementation - "CONDITIONAL: Entry #6 - {concerns}" to request changes - "REJECTED: Entry #6 - {rationale}" to block implementation **File Updated:** docs/META_LEDGER.md (entry marked CONDITIONAL) ``` ### Example 3: Scope Change (L2) **Command:** ``` /log-decision SCOPE_CHANGE "Defer PyVeritas to Phase 3" "Focus on validated features first" L2 ``` **Output:** ```markdown ✅ Meta-Ledger Updated: Entry #7 **Decision Type:** SCOPE_CHANGE (L2) **Decision:** Defer PyVeritas implementation to Phase 3 (Week 9+) **Approver:** Lead Reviewer **Status:** APPROVED **Rationale:** PyVeritas is aspirational (80% accuracy per research, not validated). Focus Phases 1-2 on working features (CBMC wrapper, Z3 integration) with proven ROI. Re-evaluate PyVeritas after baseline comparison in Week 5. **Impact:** - Phase 1-2: Tier 3 verification uses CBMC + Z3 (proven tools) - Phase 3: Evaluate PyVeritas based on validation data - Documentation: Update to reflect current vs. planned status **Timeline Impact:** None - removes unproven work from critical path **Hash Chain:** ✅ Integrity verified **File Updated:** docs/META_LEDGER.md ``` --- ## Meta-Ledger File Structure Located at: `docs/META_LEDGER.md` ```markdown # Q-DNA Development Meta-Ledger ## Auditable Decision Trail **Version:** 1.0 **Created:** 2025-12-24 **Purpose:** Merkle-chained audit trail of development decisions **Chain Status:** ✅ VALID (7 entries) --- ## Ledger Statistics - **Total Entries:** 7 - **L3 Decisions:** 2 (1 approved, 1 pending) - **L2 Decisions:** 4 - **L1 Decisions:** 1 - **Chain Breaks:** 0 - **Last Validation:** 2025-12-24 16:30:00 UTC --- ## Entry #0: Genesis (Ledger Initialization) **Type:** GENESIS **Date:** 2025-12-24 12:00:00 UTC **Approver:** System ### Decision Initialize Meta-Ledger for Q-DNA development governance. ### Hash Chain ``` Previous: 0000000000000000000000000000000000000000000000000000000000000000 Current: a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2 ``` --- ## Entry #1: ...

Create/update `docs/META_LEDGER.md` 2. Add new entry with hash chain link 3. Validate entire chain integrity 4. Flag L3 items for user approval 5. Generate approval request if needed 6. Update ledger statistics **Validation Output:** ```markdown ## Chain Integrity Validation **Timestamp:** 2025-12-24 16:30:00 UTC **Entries Validated:** 7 **Result:** ✅ PASS **Hash Verification:** - Entry #0 (Genesis): ✅ Valid - Entry #1: ✅ Valid (links to #0) - Entry #2: ✅ Valid (links to #1) - Entry #3: ✅ Valid (links to #2) - Entry #4: ✅ Valid (links to #3) - Entry #5: ✅ Valid (links to #4) - Entry #6: ✅ Valid (links to #5) **Chain Head:** c5d6e7f8a9b0c1d2e3f4a5b6c7d8e9f0a1b2c3d4e5f6a7b8c9d0e1f2a3b4c5d6 ``` --- ## Notes - Meta-Ledger is **append-only** - never delete or edit entries - L3 decisions **block implementation** until approved - Hash chain enables **tamper detection** - any modification breaks chain - Decisions are **reversible** but reversals must also be logged - **Future decisions** can reference past entries by ID - **Quarterly audits** should validate chain integrity --- **Remember:** The meta-ledger isn't bureaucracy - it's institutional memory. When someone asks "why did we choose X?", the answer is in the ledger with full context and rationale.
