Rule suppression

What it means

Rule suppression records that a team has considered a finding and chosen not to report it in a specific context. Good suppressions explain the reason, scope, owner, and review horizon. They are different from deleting a rule globally because the exception remains visible near the affected code.

Example

A parser intentionally uses a dynamic construct that a type checker cannot understand. The code includes a narrow suppression with a comment and a test that protects the invariant.

Limitations

Suppressions can become permanent bypasses when comments lack ownership or expiry. A suppression may also hide a new defect if copied into unrelated code. Prefer fixing the underlying rule or improving its model when the pattern is common.

How to use the signal

Require a narrow reason and review horizon so an exception remains an auditable decision rather than a silent bypass.

Weave can help track whether suppression-heavy changes create later rework or review questions. Keep suppression syntax and policy in the analysis system, and use workflow evidence to decide where cleanup has value.
