+## Artifact Descriptions
+
+### 1. active_intents.yaml
+
+**Purpose**: Central registry of all active intents with scope boundaries
+
+```yaml
+active_intents:
+  - id: INT-001
+    name: Add Feature to hello.js
+    status: COMPLETED  # Progressed: PENDING → IN_PROGRESS → COMPLETED
+    owned_scope:
+      - src/**/*.js                    # Primary scope
+      - tests/**/hello.test.js         # Test scope
+    constraints:                       # Implementation guardrails
+      - Must preserve backward compatibility
+      - Add proper JSDoc comments
+      - All tests must pass
+    acceptance_criteria:               # Definition of done
+      - Function executes without errors
+      - Lint check passes
+      - Unit tests pass
+      - No out-of-scope modifications
+```
+
+**Key Fields**:
+- `id`: Unique intent identifier (INT-001)
+- `status`: Current lifecycle state (COMPLETED)
+- `owned_scope`: Glob patterns defining modification boundaries
+- `constraints`: Implementation requirements
+- `acceptance_criteria`: Completeness validation
+
+**Phase Integration**: Phase 1 (Handshake)
+
+---
+
+### 2. agent_trace.jsonl
+
+**Purpose**: Immutable audit trail of code mutations with cryptographic verification
+
+**Sample Entry**:
+```json
+{
+  "intent_id": "INT-001",
+  "path": "src/hello.js",
+  "sha256": "c4fbb1500d106baea3361c209a200e8f3d7789102a1fa2c0811a58c6c124b8b0",
+  "ts": "2026-02-20T20:27:20.667Z",
+  "mutation_class": "FEATURE_ADD",
+  "description": "Added factorial function"
+}
+```
+
+**Key Fields**:
+- `intent_id`: Links mutation to specific intent
+- `path`: File modified
+- `sha256`: File content hash (64 hex characters)
+- `ts`: ISO 8601 timestamp
+- `mutation_class`: Type of change (FEATURE_ADD, REFACTOR, BUG_FIX, etc.)
+- `description`: Human-readable change summary
+
+**Key Features**:
+- **Cryptographic Verification**: SHA-256 hashes prevent tampering
+- **Intent Linkage**: Every mutation tied to an intent
+- **Append-Only**: JSONL format prevents history rewriting
+- **Timestamp Ordering**: Precise execution timeline
+
+**Phase Integration**: Phase 3 (Trace Logging) + Phase 4 (Concurrency Control)
+
+---
+
+### 3. approval_log.jsonl
+
+**Purpose**: Complete record of human-in-the-loop approval decisions
+
+**Sample Entry** (Request):
+```json
+{
+  "request_id": "approval-1771619240668-001",
+  "timestamp": "2026-02-20T20:27:20.668Z",
+  "change_summary": "Update documentation in README.md about new features",
+  "diff": "--- a/README.md\n+++ b/README.md\n@@ -1,5 +1,8 @@",
+  "files_affected": ["README.md"],
+  "intent_id": "INT-001",
+  "turn_id": "turn-001",
+  "reason": "File is outside owned_scope which is src/**/*.js"
+}
+```
+
+**Sample Entry** (Decision):
+```json
+{
+  "request_id": "approval-1771619240668-001",
+  ...request fields...,
+  "decision": {
+    "request_id": "approval-1771619240668-001",
+    "timestamp": "2026-02-20T20:27:25.668Z",
+    "approved": true,
+    "approver": "alice@example.com",
+    "approver_notes": "Documentation update is beneficial for project clarity",
+    "requires_override": true
+  },
+  "logged_at": "2026-02-20T20:27:20.668Z"
+}
+```
+
+**Key Fields (Request)**:
+- `request_id`: Unique approval request identifier
+- `timestamp`: When request was created
+- `change_summary`: Human-readable description
+- `diff`: Full unified diff of changes
+- `files_affected`: Array of modified file paths
+- `intent_id`: Associated intent

+
+**Key Fields (Decision)**:
+- `approved`: Boolean approval decision
+- `approver`: Email/identity of human approver
+- `approver_notes`: Justification for decision
+- `requires_override`: Flag for scope override
+
+**Workflow**:
+1. Agent detects out-of-scope change
+2. Creates approval request with full context
+3. Human reviewer examines diff and summary
+4. Decision recorded with approver identity
+5. Agent receives decision and proceeds/retries
+
+**Phase Integration**: Phase 5 (HITL Approval & Scope Enforcement)
+
+---
+
+### 4. intent_map.md
+
+**Purpose**: Human-readable mapping of intent to implementation with decision trail
+
+**Contents**:
+- Intent metadata (ID, name, status, dates)
+- Owned scope declaration
+- Implementation artifacts (files, functions, hashes)
+- Governance artifact references
+- Constraints and criteria tracking table
+- Decision trail with 4 milestones
+- Cross-phase integration points
+
+**Milestones**:
+1. **PENDING**: Intent created with scope boundaries
+2. **IN_PROGRESS**: Feature development starts
+3. **HITL APPROVAL**: Out-of-scope change requested and approved
+4. **COMPLETED**: All criteria met, ready for release
+
+**Value**:
+- Single source of truth for intent status
+- Links code changes to business intent
+- Tracks approval decisions
+- Documents constraint compliance
+- Enables manual code review
+
+---
+
+### 5. status_log.jsonl
+
+**Purpose**: Timestamped progression of intent through lifecycle states
+
+**Sample Entries**:
+```json
+{"intent_id":"INT-001","old_status":"NONE","new_status":"PENDING","timestamp":"2026-02-20T20:26:50.669Z","event":"Intent created"}
+{"intent_id":"INT-001","old_status":"PENDING","new_status":"IN_PROGRESS","timestamp":"2026-02-20T20:27:00.669Z","event":"Feature development started"}
+{"intent_id":"INT-001","old_status":"IN_PROGRESS","new_status":"COMPLETED","timestamp":"2026-02-20T20:27:20.669Z","event":"All criteria met, ready for release"}
+```
+
+**Key Fields**:
+- `intent_id`: Which intent transitioned
+- `old_status`: Previous state
+- `new_status`: New state
+- `timestamp`: When transition occurred
+- `event`: Human-readable description
+
+**Valid States**:
+- `PENDING`: Intent created, awaiting activation
+- `IN_PROGRESS`: Development underway
+- `COMPLETED`: All criteria met
+- `BLOCKED`: Awaiting resolution
+- `CANCELLED`: Intent abandoned
+
+---
+
+## Cross-Phase Integration
+
+### Phase 1: Intent Handshake ✅
+- Agent calls `select_active_intent(INT-001)`
+- System loads scope from `active_intents.yaml`
+- Gatekeeper validates tool access against scope
+
+### Phase 3: Trace Logging ✅
+- Every file modification recorded in `agent_trace.jsonl`
+- SHA-256 hash computed for content verification
+- Intent linkage preserved for traceability
+
+### Phase 4: Concurrency Control ✅
+- File hashes enable stale file detection
+- Multiple agents working on different intents won't conflict
+- Optimistic locking prevents lost updates
+
+### Phase 5: HITL Approval ✅
+- Out-of-scope changes trigger approval request
+- Human decisions recorded in `approval_log.jsonl`
+- Override decisions auditable and timestamped
+
+## Compliance & Audit
+
+### Data Integrity
+- ✅ All timestamps in ISO 8601 format
+- ✅ All hashes 64-character hex (SHA-256)
+- ✅ JSONL format (one valid JSON object per line)
+- ✅ No mutable data (append-only logs)
+
+### Audit Trail
+- ✅ Every change linked to an intent
+- ✅ Every mutation has cryptographic hash
+- ✅ Every approval has approver identity
+- ✅ Every status transition timestamped
+
+### Compliance
+- **SOC 2**: Complete audit trail with timestamps
+- **HIPAA**: Human oversight for critical changes
+- **GDPR**: Approver identity and decision tracking
+- **Governance**: Scope enforcement prevents drift
+
+## Usage Examples
+
+### Query Intent Status
+```bash
+grep "INT-001" .orchestration/active_intents.yaml
+```
+
+### Verify File Hash Integrity
+```bash
+sha256sum src/hello.js  # Compare with agent_trace.jsonl sha256 field
+```
+
+### Track Approval Decisions
+```bash
+jq '.decision | select(.approver == "alice@example.com")' .orchestration/approval_log.jsonl
+```
+
+### View Status Timeline
+```bash
+cat .orchestration/status_log.jsonl | jq '.timestamp, .event'
+```
+
+### Find Out-of-Scope Requests
+```bash
+grep "out_of_scope" .orchestration/approval_log.jsonl
+```
+
+## Lessons Learned
+
+Education artifacts documenting verification failures and resolutions:
+
+**Entry Example**:
+```
+## Lesson Learned (2026-02-20)
+
+**Context**: Lint check on hello.js during INT-001 feature implementation
+**Failure**: ESLint detected missing semicolons in factorial() function (5 instances)
+**Resolution**: Added semicolons to all statements; enabled 'semi' rule in .eslintrc.json
+```
+
+**Location**: `CLAUDE.md` (root directory)
+
+## Future Enhancements
+
+- [ ] Approval routing (different teams for different scopes)
+- [ ] SLA tracking (approval decision latency)
+- [ ] ML-based scope learning (suggest scope boundaries)
+- [ ] Auto-approval (for low-risk, high-confidence changes)
+- [ ] Metrics dashboard (approval rates, decision times)
