External takeLatest traces with controlled stale responses

[PerchAnton]

I made an external Redux Saga example for interaction-check, a JSONL regression runner I maintain. It uses runSaga/stdChannel and a small original worker instead of real timers or network requests.

The traces check that takeLatest cancels the previous worker, a late response cannot produce a result, stopping the root cancels pending work, and a completed worker is not reported as cancelled. Would this be useful as an optional reproduction recipe? Timing and browser behavior remain outside the example.

Adapter · Three traces · External PR. Tested with redux-saga 1.5.1: 3 scenarios / 14 steps pass locally on macOS, Node 24.19.0.

From that checkout, with Python 3.10+ and Node 24.19.0:

npm --prefix adapters/javascript ci --ignore-scripts --no-audit --no-fund
python interaction_check.py scenarios/redux-saga/*.json -- node adapters/javascript/main.mjs redux-saga
