Jason Smith enhanced access control in the dpc-sdp/tide_core repository by refining role-based permissions to strengthen security and governance. He implemented a feature that revoked delete permissions from editor, approver, and approver_plus roles, enforcing the principle of least privilege while maintaining operational flexibility. To support organization term lifecycle management, Jason extended CRUD permissions for the approver_plus role without granting delete access. These changes were applied through the tide_core.install deployment script, ensuring consistent enforcement across environments. Working primarily with PHP and Drupal, Jason’s backend development focused on precise permission management, delivering a targeted solution that addressed business risk without introducing unnecessary complexity.
