+## [2026-02-16]
+
+### Added
+- Added customer-to-jobs navigation by making customer names clickable on the Customers page, linking to `/jobs?customer_id=<id>`
+- Added Jobs page customer filter context UI with an active filter banner and a "Clear filter" action
+
+### Changed
+- Changed `/jobs` route to accept optional `customer_id` query parameter and return only jobs for that customer when provided
+- Changed default Jobs listing behavior to keep existing inactive-customer filtering only when no `customer_id` filter is applied
+
