Only the root raw-artifact read received the request signal. Lineage discovery and descendant reads could continue after disconnect, response-body cancellation did not stop the producer, and the root error boundary converted an abort rejection into an ordinary HTTP 500. Combine request and response-consumer cancellation into the ZIP producer signal, forward it through every cancellable read, check it around the attachment seam, and terminate fflate exactly once when production stops. The pre-stream boundary now rethrows the original abort instead of translating it. Regression tests cover signal propagation, exact cancellation identity at the HTTP boundary, and a reader cancellation interrupting an in-flight descendant read; the bilingual host contract records these lifecycle semantics.
host/ — web-GUI host half
English | 中文
The host side of the dsh web GUI: the API gateway every client shape shares, and the plain HTTP server it rides on. The browser side lives in client/; the composed application is apps/cli booting the dsh-base bundle serving apps/web. All product packages.

apiproxy remains transport-independent; client/connection supplies the browser/HTTP carrier. Picker implementations replace one another behind the shared seam.
The subsystem references: http-server.md and workspace.md (the picker seam).
