## Provenance Metadata

| Field | Value |

| operatorAssistant | "Codex-assisted operation" |
| repairSystem | "LEONA by DLG Labs" |
| repairMode | "DETERMINISTIC_REPLAY" |
| modelProvider | "not applicable" |
| modelName | "not applicable" |

## Operator Disclosure

Codex was used as a development/operator assistant to launch commands, inspect outputs, and guide repository maintenance. LEONA performed the governed repair benchmark execution through its own validation layer, rollback system, mutation constraints, and telemetry generation.

## Claim Boundary

This validates the benchmark harness, mutation boundaries, rollback system, telemetry, and evidence pipeline. It does not prove unknown-bug autonomous reasoning.

## Summary
- Attempts: 5
- Passed: 5/5
- Test files modified after baseline: 0
- Unauthorized mutation attempts: 0
