## ADDED Requirements

### Requirement: AIOps sessions SHALL persist lightweight rule evaluation
When an AIOps final report is persisted, the system SHALL evaluate it with deterministic AIOps-specific quality rules and store the result in session self-evaluation.

#### Scenario: Payload-focused report is evaluated
- **WHEN** an AIOps session has alert payload fields and a final report is persisted
- **THEN** the system SHALL evaluate whether the report mentions the supplied alert and service
- **AND** it SHALL store the result under `self_evaluation.aiops_rule_evaluation`

#### Scenario: Evidence coverage is evaluated
- **WHEN** an AIOps final report is evaluated
- **THEN** the system SHALL check whether evidence tool invocations such as `lookup_knowledge`, `query_metrics`, or `query_logs` were persisted for the session

#### Scenario: Evaluation is traceable
- **WHEN** the diagnosis trace API returns an AIOps session
- **THEN** the session self-evaluation payload SHALL include `aiops_rule_evaluation` when it has been generated

#### Scenario: Evaluation uses stable verdicts
- **WHEN** AIOps rule evaluation completes
- **THEN** it SHALL produce a verdict from `PASS`, `WARN`, or `FAIL`
- **AND** it SHALL include check details and a human-readable rationale
