is then summed with a "PIN offset" stored on the card itself, modulo 10, to
These optimizations are difficult to implement, frequently error-prone, and lead to inconsistent behavior across runtimes. Bun's "Direct Streams" optimization takes a deliberately and observably non-standard approach, bypassing much of the spec's machinery entirely. Cloudflare Workers' IdentityTransformStream provides a fast-path for pass-through transforms but is Workers-specific and implements behaviors that are not standard for a TransformStream. Each runtime has its own set of tricks and the natural tendency is toward non-standard solutions, because that's often the only way to make things fast.。关于这个话题，Line官方版本下载提供了深入分析

Instead of tee() with its hidden unbounded buffer, you get explicit multi-consumer primitives. Stream.share() is pull-based: consumers pull from a shared source, and you configure the buffer limits and backpressure policy upfront.
