I feel this so much. File IO on flaky or network drives is a nightmare, and blocking calls make it worse. It’s good to see the async iterator and substring search moving forward, though it still feels a bit fragile with the thread workaround.

One thing I wonder is how you plan to handle cases where files vanish or change mid‑operation. Will the API just bubble up errors, or do you plan to hide some of that under retries or caching?

Overall, really enjoying these devlogs. Seeing the tradeoffs laid out like this is helpful for anyone building similar tools. Keep it up.
