+**Implementation Attempt** — Tier 0: gpt5-mini — Failed
+
+Attempted to run the full local quality gates for PR #8193 (branch: improve/agent-evolution-pool-supervisor-metadata). Summary:
+
+- What I ran: nox -e lint, nox -e typecheck, nox -e unit_tests, nox -e integration_tests
+- Outcome: lint ✓, typecheck ✓ (3 warnings), unit_tests ✓, integration_tests ✗
+
+Error details (integration_tests):
+- Multiple Robot Framework suites failed (examples):
+  - Robot.E2E.Wf17 Project Exec Env Priority — Parent suite setup failed: CleverAgents command failed with rc=1
+  - Robot.Cli Init Fresh Environment — OperationalError: table changeset_entries already exists
+  - Several suites were killed with exit code -9 (likely OOM or resource limits)
+
+Diagnosis: environment/test-runner issues (contaminated DB, resource limits, or parallelism causing shared-state failures).
+
+What I did: created an isolated clone at /tmp/task-implementor-repo-1 and ran the quality gates locally; I did not apply source changes because failures appear environmental.
+
+Next steps: inspect CI logs for failing integration jobs, re-run tests in a clean environment with reduced concurrency, or provide CI failure logs/target URLs for deeper debugging.
