Flux 2.0 Migration

Flux 2.0 redesigns streams around returned teardowns, pipe(), explicit buffers, channels, adapter sub-paths, and terminal consumer names.

Replace subscription cleanup

Update stream consumers to retain and invoke the teardown returned by the 2.0 subscription contract. Do not rely on removed subscription-lifecycle shapes.

Compose with pipe()

Build stream transformations through pipe() and current operators. Update creation, transformation, filtering, and terminal consumption to their 2.0 names.

Make buffering explicit

Configure buffering and overflow behavior through the 2.0 stream and channel APIs. Review every source that can outpace its consumer.

Review the Usage Guide and API Reference for current streams, adapters, operators, and teardown contracts.
