 # Lifecycle Objective Milestone Gate Report
 
-**Status:** PASS  
-**Date:** 2026-07-20
+## Gate Metadata
 
-| Criterion | Status | Evidence |
-| --- | --- | --- |
-| Problem statement defined | PASS | `intake/intake-form.md` |
-| Success metrics defined | PASS | Five measurable criteria in intake |
-| Stakeholders identified | PASS | Five stakeholder groups in intake |
-| Initial risk screening complete | PASS | Seven risks in `intake/risk-screening.md` |
-| Solution approach viable | PASS | Existing operational codebase; no infeasible constraint |
+- **Decision:** PASS WITH CONDITIONS
+- **Evaluation date:** 2026-07-21
+- **Scope:** Brownfield lifecycle objectives, owner context, initial risk, and solution viability
+- **Evaluator:** Artifact standards audit; named maintainer approval pending
 
-The gate authorizes brownfield elaboration. Unknown adoption, staffing, and SLO facts remain owner inputs but do not prevent documenting current architecture.
+## Criteria and Evidence
+
+| Criterion | Threshold | Status | Citable evidence |
+| --- | --- | --- | --- |
+| Problem and outcomes | Problem, stakeholders, scope, measurable success criteria | PASS | Intake form and project intake |
+| Owner intent | Priority, scale context, failure posture, commitments recorded | PASS | Option matrix owner answers and decision record |
+| Initial risk | Impact/likelihood/exposure/owner/status/residual risk for critical domains | PASS | Risk register R-001–R-010 |
+| Quality constraints | Critical NFRs are measurable with repeatable verification | PASS | NFR-01–NFR-12 register |
+| Solution viability | Implemented brownfield path exists; no infeasible constraint identified | PASS | Codebase report, SAD, current CI |
+| Ownership | Named owners/reviewers assigned | CONDITION | Roles defined, assignments pending |
+
+## Conditions and Residual Uncertainty
+
+1. Assign named architecture, safety, evaluation, test, and release owners before a release/maturity decision relies on role approval.
+2. Treat the thousands-to-tens-of-thousands scale as owner-supplied planning context, not measured telemetry.
+3. Do not infer hosted SLOs, general support commitments, or certification from the current local/open-source baseline.
+
+## Decision Rationale
+
+The gate authorizes brownfield elaboration/construction-alignment work because the problem, current solution, success criteria, risks, owner intent, and critical quality constraints are explicit. The ownership condition affects review evidence but does not prevent documenting or testing the implemented baseline.
