+# Feature Discovery → GA Development Prompt (Summit Standard)
+
+> **Operating Rule:** Never defend the past. Only assert the present and dictate the future.
+> **Escalate before anyone asks:** reference the [Summit Readiness Assertion](SUMMIT_READINESS_ASSERTION.md).
+> **Move the fight to paper:** cite files, not opinions.
+
+## Mission
+Identify an experimental, orphaned, or underdeveloped feature within **[PROJECT_NAME]** and advance
+it to **GA** with production-quality engineering, full evidence, and enterprise-grade reliability.
+Deliver a complete production package: architecture, implementation, tests, documentation, CI/CD,
+security posture, observability, and a merge-ready PR package.
+
+## Inputs Required (Do Not Start Without)
+- Repository path / URL
+- Target timeline
+- Change class (`patch`, `minor`, `major`)
+- Priority axis (user impact, security, reliability, or platform efficiency)
+- Explicit non-goals
+
+## Execution Constraints
+- **Evidence-first output:** publish UEF before narrative conclusions.
+- **Reversibility:** every decision has rollback trigger + steps.
+- **Policy alignment:** no bypass of GA/Security/Evidence gates.
+- **Boundary discipline:** one primary zone per change unless explicitly coupled.
+- **Golden main readiness:** every milestone must be merge-safe and CI-clean.
+
+## Phase 0 — UEF Evidence Protocol (Mandatory)
+Provide raw evidence before conclusions:
+- File paths + line ranges
+- Git history references (commit IDs)
+- Coverage artifacts and test evidence
+- Issue tracker links
+- Feature flags / configuration toggles
+- Risk register + mitigation mapping
+
+## Phase 1 — Discovery & Assessment
+**Task:** audit the repository for candidate features.
+
+**Search Criteria**
+1. Experimental: feature flags, beta/labs/preview tags
+2. Orphaned: no commits in >6 months, missing ownership
+3. Underdeveloped: missing tests, incomplete flows, absent docs
+
+**Analysis Requirements**
+- Locate TODOs, feature flags, and experimental annotations
+- Review git history for stale ownership and abandoned branches
+- Check test coverage gaps
+- Review issue tracker for blocked/postponed requests
+- Assess user feedback and telemetry signals
+
+**Deliverable:** prioritized candidates with
+- Feature name + file locations
+- Completion estimate (%)
+- Test coverage status
+- Documentation status
+- Business value estimate
+- Technical debt score
+- Effort estimate to GA
+
+## Phase 2 — Selection & Planning
+**Selection Criteria (1–10 weighted):**
+- User demand / business value
+- Technical feasibility
+- Strategic alignment
+- Risk of breaking changes
+- Dependencies / blockers
+
+**Planning Deliverables**
+1. Technical Specification
+   - Scope + requirements
+   - Architecture + integration points
+   - API contracts + data models
+   - Security/compliance considerations
+   - Performance targets + SLAs
+2. Gap Analysis
+   - Missing functionality
+   - Test coverage gaps
+   - Documentation gaps
+   - Infra/monitoring gaps
+3. Development Roadmap
+   - Milestones + acceptance criteria
+   - Timeline + resource profile
+   - Risk mitigation plan
+   - Rollback strategy
+
+## Phase 3 — GA Implementation Standards
+**Code Quality**
+- Production-grade refactor
+- Typed error handling and edge-case coverage
+- Logging + instrumentation
+- Performance profiling
+- Security review
+
+**Testing (target ≥80% for changed surfaces)**
+- Unit tests
+- Integration tests
+- End-to-end tests
+- Regression suite
+- Performance/load tests
+- Security tests
+
+**Documentation**
+- API documentation
+- User-facing documentation
+- ADRs
+- Runbooks
+- Migration guide (if needed)
+
+**Infrastructure & Operations**
+- CI/CD integration
+- Deployment automation
+- Monitoring + alerting
+- SLO/SLA definitions
+- Rollback procedures
+- Feature-flag rollout strategy
+
+## Phase 4 — Pre-GA Validation
+**Beta Program**
+- Define cohort
+- Feedback collection loop
+- Exit criteria
+- Canary rollout model
+
+**GA Readiness Checklist**
+- Acceptance criteria met
+- Test coverage achieved
+- Documentation complete
+- Performance benchmarks validated
+- Security audit passed
+- Support + incident response ready
+- Stakeholder sign-off complete
+
+## Phase 5 — Launch & Post-GA
+**Launch**
+- Production deployment
+- Release notes
+- User communication
+- Real-time KPI monitoring
+
+**Post-Launch (30 days)**
+- Daily monitoring
+- Weekly retrospectives
+- Bug triage + hotfix path
+- Optimization backlog
+
+## MAESTRO Threat Model Alignment
+For every proposed change, explicitly state:
+- **MAESTRO Layers:** [Foundation, Data, Agents, Tools, Infra, Observability, Security]
+- **Threats Considered:** [goal manipulation, prompt injection, tool abuse, data exfiltration]
+- **Mitigations:** [policy gates, input validation, least-privilege, audit logging]
+
+## Summit Verification Command Pack
+Run and report pass/fail for the applicable set:
+- `node scripts/check-boundaries.cjs`
+- `pnpm lint`
+- `pnpm format:check`
+- `pnpm typecheck`
+- `pnpm test`
+- `make smoke`
+
+If constraints prevent full execution, mark each constrained command as
+**Intentionally constrained** with reason and next runnable environment.
+
+## Required Artifacts (Per Change)
+- `decision-rationale.md` (why now, confidence 0–1, alternatives)
+- `rollback-plan.md` (trigger thresholds + exact actions)
+- `test-plan.md` (tiers, commands, expected evidence)
+- `release-notes.md` (customer-facing and operator-facing)
+- `risk-register.md` (risk, likelihood, impact, mitigation, owner)
+
+## Output Format (Strict)
+1. **High-Level Summary + 7th+ Order Implications**
+2. **Full Architecture** (diagrams + integration map)
+3. **Implementation** (all files, no placeholders)
+4. **Tests** (unit, integration, e2e, performance, security)
+5. **Documentation** (README, dev guide, ops guide, API docs)
+6. **CI/CD** (pipelines, quality gates, evidence artifacts)
+7. **PR Package** (commit history, PR body, reviewer checklist)
+8. **Future Roadmap** (post-GA enhancements)
+9. **UEF Evidence Bundle**
+10. **Final GA Checklist**
+
+## PR Package Requirements
+- **Commit history:** commits listed with intent and scope.
+- **PR description:** what, why, how, risk, rollback, accountability window.
+- **Reviewer checklist:** tests, security, compliance, docs, rollout safety.
+- **Merge readiness summary:** gate status + evidence links + residual risk.
+- **Post-merge validation plan:** metrics, thresholds, owners, response timing.
+
+## Forward-Leaning Enhancement
+Implement a **GA Readiness Scorecard** in CI that blocks merge unless evidence,
+tests, docs, and rollback criteria meet minimum thresholds.
+
+## Example Invocation
+```text
+Use this prompt to identify and GA-ify any suitable feature in [REPOSITORY_NAME].
+Start with Phase 1 discovery and return a prioritized list.
+Then select one feature and produce the full GA plan.
+
+Repository: [path or URL]
+Timeline: [X weeks]
+Change class: [patch|minor|major]
+Priority Constraints: [security-critical | user-facing | reliability-first]
+Non-goals: [explicit exclusions]
+```
