December 2025: Navigation and URL routing fixes in Rocket.Chat/Rocket.Chat. Addressed two critical user-facing routing issues to improve login flow and cross-channel navigation: (1) router matching after login when 'First Channel After Login' starts with a hash, fixed by stripping leading hashes and redirecting correctly; (2) Global Search 'Jump to message' URL generation to reliably navigate to messages across channels. These fixes reduce navigation friction and improve global search reliability. Delivered via two commits with clear traceability. Impact: more reliable user navigation, improved search accuracy across channels, and smoother onboarding. Skills demonstrated: frontend routing, URL normalization, and collaborative code review.
