+"""Lightweight, decoupled progress reporting for long-running scheduler jobs.
+
+A job's work function calls `report(current, total, phase)`; the scheduler binds a sink (via
+`bind()`) that forwards it into the in-memory activity the admin dashboard polls. A contextvar
+holds the sink, so the sync code stays unaware of the scheduler and concurrent jobs (each in
+its own thread/context) never cross wires. When no sink is bound (e.g. a manual sync endpoint),
+`report` is a cheap no-op.
