Standalone worker that prunes stale rows from `propagation_scores`.
|
|
|
|
Pruning used to be tacked on to the end of `PropagationGridWorker.perform/1`,
|
|
which meant it only ran after a successful grid compute. When the compute
|
|
worker was being killed mid-run (OOM / SIGTERM), prune never ran and the
|
|
table grew unbounded. Running prune on its own cron keeps the table healthy
|
|
regardless of the compute worker's state.
