 ### Added
 
+- **Issue Enrichment Automation — Definition of Ready & Done Framework** — Comprehensive issue enrichment system providing automated detection and completion of missing Definition of Ready (DoR), Definition of Done (DoD), Owner, and Acceptance Criteria sections. Deliverables: (1) **Audit Script** (`scripts/automation/audit-issue-completeness.js`) — Analyzes all issues to identify missing sections, calculates completeness scores (0-100%), aggregates statistics by type/status/area, and generates JSON/CSV reports. Audit of 100+ issues with `status:needs-more-info` label identified 91% missing DoR, 73% missing DoD, 71% missing Owner, 45% missing Acceptance Criteria. (2) **Enrichment Script** (`scripts/automation/enhance-issue-completeness.js`) — Automatically adds missing sections with type-specific templates (features: 7 items, bugs: 6 items, epics: 6 items, default: 4 items); preserves existing content; auto-removes `status:needs-more-info` label on completion; supports dry-run preview and auto-owner assignment modes. (3) **Documentation** (`scripts/automation/ISSUE-ENRICHMENT-README.md`, 600+ lines) — Comprehensive guide covering quick-start examples, detailed API reference, workflow integration patterns (scheduled Monday 9 AM & manual verification), performance characteristics (100 issues in 5-8 minutes), rate limit handling, troubleshooting guide, and best practices. (4) **Improvement Plan** (`IMPROVEMENT-PLAN-ISSUES-AGENT-2026-09-04.md`) — Complete strategic analysis of completeness gaps with root cause analysis, business impact assessment (development delays, scope creep, quality risk), 4-week implementation roadmap, success metrics (target 95% for DoR/DoD/Owner, 90% for AC, 85% avg completeness), and risk mitigation strategies. **Scripts Features**: Type-specific DoR/DoD templates with comprehensive checklists, automatic label management, dry-run mode for safe preview, JSON/CSV reporting with aggregated statistics, pagination support (limit/start-from), error handling with detailed logging, Node.js HTTPS-based GitHub API integration. **Metrics Addressed**: Issues with DoR 9% → Target 95% (2 weeks), DoD 27% → Target 95% (2 weeks), Owner 29% → Target 95% (1 week), Acceptance Criteria 55% → Target 90% (2 weeks), Average Completeness 32% → Target 85% (3 weeks). **Integration**: Seamlessly integrates with existing Issues Agent (`agents/issues.agent.md`); complements type detection and labeling workflows; scripts are independently useful for audit, dry-run preview, or bulk enrichment; production-ready with gradual rollout strategy.

 - **Milestone Automation — Phase 2 Follow-Up: CodeRabbit Findings Remediation** — Completed first phase of 28-item CodeRabbit review remediation for milestone distribution automation system. Phase 2 Follow-Up delivers: (1) **FOLLOW-UP-FIXES.md Tracker** — Comprehensive 28-item tracker categorizing findings into Critical Fixes (4/4 resolved: security vulnerabilities, error handling, metrics persistence, rate limit handling), Important Fixes (3/3 resolved: transaction documentation, job status masking, evidence alignment), Polish Fixes (3/3 resolved: calculation errors, Block Kit formatting, README/STATUS alignment), and CI Investigation Items (18 pending: validation checks #11-24, infrastructure requirements #25-28); (2) **Frontmatter Schema Validation** — Completed validation of all 24 milestone-automation files plus 16 additional project documentation files with proper frontmatter compliance (status enum, file_type values, owner fields); (3) **Project Linking Compliance** — Added "Related Issues" sections to all 84 active projects including copilot-branch-enforcement-2026-09-03 and three projects missing README files (labeling-consolidation-2026-09-03, workflow-automation-fixes-phase2/3); (4) **Documentation Synchronization** — Updated OPENSPEC.md (v1.1.0), STATUS.md, README.md, and created ISSUE-LINKS.md linking project to GitHub issues (#1852 umbrella, #1524, #786, #1673, #1129); (5) **Phase 3 Implementation Plan** — Structured 4-step Phase 3 roadmap (documentation validation, labeling audit, infrastructure upgrade, final CI validation) targeting 2026-09-10 completion. Progress: 13/28 findings resolved (46% complete). All milestone-automation files passing frontmatter schema validation (24/24 ✓). Project linking compliance verified (84/84 projects ✓). Related issues tracked and cross-linked for Phase 2 continuation. See [Phase 2 Follow-Up Project](.github/projects/active/milestone-automation/) for complete documentation.
