Mutation Review

Use this artifact for a bounded mutation-guided test-hardening review. Keep the project's native tool output as the authoritative raw report; this is a review record, not a portable report schema.

Change And Scope

• Review/change concern:
• Expected behavior:
• Base commit:
• Exact candidate/head commit:
• Target files/lines:
• Scope rationale:

Run Configuration

• Tool and version:
• Configuration:
• Operator set:
• Seed:
• Test command:
• Mutant budget:
• Per-mutant timeout:
• Exclusions and rationale:
• Environment:
• Raw report location:

Baseline Result

• Command and commit:
• Result:
• Relevant output/evidence:

Mutants

Stable ID	Location	Operator	Status	Disposition	Evidence
			killed / survived / equivalent-or-likely-equivalent / no coverage / timeout / flaky / invalid / infrastructure-tooling failure

Accounting

• Denominator formula:
• In-scope mutants:
• Classified mutants:
• Excluded mutants:
• Unknown or incomplete mutants:
• Infrastructure/tooling failures:
• Explanation of any difference:

Unknown, incomplete, excluded, and failed outcomes must remain visible; they do not silently become killed or leave the denominator.

Candidate Test

• Proposed test and expected behavior:
• Why this tests behavior rather than implementation:
• Behavioral relevance:
• Non-tautology/non-vacuity check:
• Non-redundancy and maintainability check:
• Flake-risk check:
• Implementation-coupling check:

Independent Verification

• Baseline-test result:
• Exact-mutant-kill result:
• Repeat/flake result:
• Independent verifier:
• Verification timestamp/identity:
• Evidence locations:

Decision

• Human reviewer decision:
• Uncertainty and limitations:
• Rerun/reproduction command:
• Follow-up owner and due date:
