+## v20260120-07-autotask-psa-resolution-handling
+
+- Added support for linking existing Autotask tickets (Phase 2.2) using Autotask REST queries.
+- Implemented ticket listing by company with exclusion of terminal tickets (status != Complete).
+- Added search support for existing tickets by exact ticketNumber and by title (contains).
+- Implemented authoritative validation of selected Autotask tickets via GET /Tickets/{id}.
+- Defined terminal ticket detection based on:
+  - status == Complete (5)
+  - OR completedDate is set
+  - OR resolvedDateTime is set.
+- Ensured terminal Autotask tickets automatically resolve the corresponding internal Backupchecks ticket.
+- Preserved legacy internal Ticket and TicketJobRun creation/linking so Tickets overview, Tickets/Remarks, and Job Details continue to function identically to manually linked tickets.
+- Ensured resolution timestamps are derived from Autotask (resolvedDateTime / completedDate) instead of using current time.
