Risky codepaths keep sanitizer and race-detector coverage

test-017

Intent

Existing dynamic-analysis coverage for risky native or concurrent code should not be removed casually, because those tools often catch failures ordinary tests miss.

Applicability

Applies when the diff changes sanitizer, race-detector, or comparable dynamic-analysis jobs for code that uses concurrency, native memory, unsafe operations, or similar high-risk behavior. Return unknown when the repository has no such tooling.

What to inspect

Review CI jobs, test targets, build flags, and exclusions around dynamic-analysis coverage for risky codepaths.

Pass criteria

Existing sanitizer or race-detector coverage for risky paths remains in place, or an equivalent replacement is introduced explicitly.

Fail criteria

The diff disables, removes, or narrows existing sanitizer or race-detector coverage for risky codepaths without an equivalent replacement.

Do not flag

Repositories with no such tooling, harmless renames that preserve coverage, or deliberate replacement with an equivalent stronger job.

Confidence guidance

HIGH when a coverage job or target is plainly removed. MEDIUM when coverage narrowing is inferred from CI or build-config changes. LOW when the risk profile of the codepath is unclear.

Remediation

Keep the existing dynamic-analysis coverage, or replace it with an equivalent path that still covers the risky code.

Pass example

jobs:
  race-tests:
    steps:
      - run: go test -race ./pkg/concurrent/...

Fail example

jobs:
  unit-tests:
    steps:
      - run: go test ./pkg/concurrent/...

# The prior -race coverage for this package was removed.
