X_ABORTED
Means
operation aborted
Typical cause
the AbortSignal on ctx fired: client disconnected, or a deadline passed — including a job past its timeout, whose steps are refused from that point on
Fix
add throwIfAborted(ctx) before expensive work, and make each vendor call with outbound({ url, vendor, dial, deadlineMs }) from @ultimat3/core/outbound, which hears ctx.signal — unwind at the deadline instead of running past it
