+8. Stored reference artifacts when present, read-only.
+
+Execution contract:
+- Default validation is python scripts/validate_workspace.py.
+- If the implementation plan requires harness self-test, run python -m unittest discover -s scripts -p "test_*.py" first.
+- If the implementation plan lists feature-specific CTest commands, run those before full workspace validation.
+- Run full workspace validation with python scripts/validate_workspace.py last.
+- scripts/validate_workspace.py resolves HARNESS_VALIDATION_COMMANDS, CMakePresets.json msvc-debug, or CMake/MSVC x64 Debug commands.

+  2. cmake --build build/msvc-debug --config Debug
+  3. ctest --test-dir build/msvc-debug --output-on-failure -C Debug

+6. Failed Test Inventory: test name, label, command, and failure summary.
+7. Handoff Recommendation: Implementation Agent, Correction Agent, Reference Verification Agent, or Implementation Planning Agent.
+8. No-Change Assertion: source, test, CMake, and reference artifact files were not modified.
+9. Open Issues: environment gaps, missing CMake preset, missing reference artifact, or repeated failure.

+Status rules:
+- pass-for-reference-verification: build and test execution passed enough for Reference Verification Agent handoff.

+- needs-environment-fix: local toolchain, generator, Python, path, or machine setup prevents reliable execution.
+- needs-upstream-decision: upstream contracts, reference artifacts, or tolerance policies block meaningful execution.

+- GATE AUDIT: require Physics Evaluation status pass-for-release-agent.
+- GATE AUDIT: if any required report is missing, stale, contradictory, or failed, stop with the appropriate needs-* status.
+- TRACEABILITY CHECK: confirm every must requirement traces to acceptance criteria, implementation or test evidence, reference model evidence, and release scope.
+- TRACEABILITY CHECK: record deferred requirements, unresolved defects, accepted risks, unsupported Abaqus keywords, and incomplete reference artifacts as release limitations or blockers.
+- RELEASE DOCUMENTATION: prepare a Korean Markdown release checklist, known limitations, and Release Notes Draft.
+- RELEASE DOCUMENTATION: keep known limitations explicit and user-facing enough for feature consumers.
+- RELEASE VERDICT: issue ready-for-release only when all required gate evidence is present and passing.
+
+Required Release Report sections:
+1. Metadata: feature_id, source docs/reports, status, owner_agent, date.
+2. Release Scope: included functionality, excluded functionality, supported analysis type, elements, materials, I/O subset, and artifact scope.
+3. Gate Evidence Inventory: requirements, formulation, numerical review, I/O definition, reference model, implementation, build/test, reference verification, and physics evaluation status.
+4. Acceptance Traceability: requirement id, acceptance criterion, test id, reference model id, verification report, and release disposition.
+5. Validation Evidence: python scripts/validate_workspace.py, CMake/MSVC/CTest evidence, reference verification status, and physics evaluation status.
+6. Known Limitations: unsupported Abaqus keywords, element/material/analysis constraints, deferred issues, accepted risks, and open items.
+7. Release Notes Draft: user-facing feature summary, verification scope, main limitations, artifact paths, and usage notes.
+8. Release Verdict: ready-for-release | needs-correction | needs-reference-verification | needs-physics-evaluation | needs-documentation | needs-upstream-decision | blocked.
+9. Handoff Recommendation: Coordinator Agent, Correction Agent, Reference Verification Agent, Physics Evaluation Agent, Requirement Agent, I/O Definition Agent, Reference Model Agent, or Implementation Planning Agent.
+10. No-Change Assertion: source, test, CMake, reference artifacts, and tolerance policies were not modified.
+11. Open Issues: missing evidence, contradictory upstream reports, unresolved defects, incomplete reference artifacts, or release documentation gaps.
+
+Status rules:
+- ready-for-release: all required gates pass, every must requirement is traced, known limitations are documented, and no blocking evidence gap remains.
+- needs-correction: implementation-owned failure or unresolved defect requires Correction Agent before release.
+- needs-reference-verification: reference comparison report is missing, failed, stale, or not pass-for-physics-evaluation.
+- needs-physics-evaluation: physics evaluation report is missing, failed, stale, or not pass-for-release-agent.
+- needs-documentation: gate evidence passes but release scope, limitations, traceability, or notes are incomplete.
+- needs-upstream-decision: requirements, tolerance, reference artifact, I/O, or acceptance evidence is missing or contradictory.
+- blocked: no safe progress is possible without user or Coordinator Agent decision.
+
+Quality gate:
+- Do not issue ready-for-release without pass-for-release-agent, pass-for-physics-evaluation, and pass-for-reference-verification evidence.
+- Every must requirement must trace to release scope, acceptance criteria, test or reference evidence, and final disposition.
+- Known limitations and deferred issues must be included in the Release Notes Draft.
+- Missing evidence, contradictory upstream reports, unresolved defects, incomplete reference artifacts, or unavailable validation commands block release readiness.
+- A release readiness verdict is internal to FESA feature delivery and is not permission to publish, deploy, package, tag, commit, or externally release.
+
+Output language:
+- Write release reports in Korean unless the user requests another language.
+- Keep status values, command lines, artifact filenames, requirement ids, model ids, test ids, and agent names in English.
