[ARI-34] Validate AC-02 — Affected resource identification accuracy

[bjridicodes]

Linear: ARI-34

Type: 🔵 User Story | Sprint: 7 | Points: 3 | AC: AC-02

As an on-call engineer, I want ARIA to correctly identify the affected resource in at least 80% of incidents so that log queries and notifications target the right host.

Acceptance Criteria

Given 10 test incidents are processed
When affected_ci in each result is compared to the known ground truth
Then at least 8 of 10 match (≥80% accuracy — AC-02)

Given an incident with an empty cmdb_ci field
When Agent 1 applies the regex fallback
Then the extracted hostname is recorded and compared to the expected value

Given AC-02 results are recorded
Then the accuracy percentage and any misses are documented in the acceptance test report
