- Add bounded fuzzing for rules, package parsers, credential redaction, and scan state. Fix newline and Unicode glob-matching bugs, retain regression inputs, and document the test plan.
- Run short PR and longer nightly campaigns with failure artifacts. Nine targets passed 3.6 million local executions; race tests, smoke tests, lint, and cross-platform builds passed.
