The fix that helped the most, I stumbled into completely by accident - and it had nothing to do with the code I’d been sweating over 😅 .

Here’s the whole embarrassing, hopefully useful story.

The service was a data collector - high-throughput ingest with backpressure, checkpointing, retries, the usual. The design was simple: one thread reads batches of records off a source on a tick, hands them to another thread over a channel, and that thread ships them to a destination.
