 ### Changed
 
+- Triaged CodeQL findings by removing duplicate `re` imports, making deliberate test string concatenation explicit, and avoiding secret-like test fixture naming that produced false-positive clear-text storage alerts.
 - Synced Dependabot malware alerts and grouped security updates documentation with follow-up Advanced Security UI evidence, while keeping Dependabot version updates deferred.
 - Synced product strategy and support public-truth wording with v0.3.0, and expanded the post-release audit guard for stale version and private reporting claims.
 - Improved PyPI package metadata with SPDX license metadata, explicit license files, project URLs, and additional classifiers.
