November 2025 monthly summary for Sublime Security development. Delivered two high-impact changes across two repositories: (1) Sublime Security / static-files: Self-Service Creation Platform Domain Simplification, consolidating Jotform domains to retain only jotform.com to simplify domain management and reduce usage errors; (2) Sublime Rules / sublime-rules: Credential Phishing Detection Enhancement for Corporate Services, expanding the detection regex to cover 'operations department' language to better identify HR-related impersonation.
