Flow Next v1.8.3 — standalone preview

First standalone public distribution of Flow Next 1.8.3, an experimental native agent preset for DeepSeek Harness 0.2.1-rc.2.

In DSH's Plugins page, install:

https://github.com/sonwe1e/dsh-flow-next.git#v1.8.3

It combines native/PTC interface selection, task context, execution evidence, and stage reports while retaining the host's permission controls. The entrypoint mounts only Flow Next; the private research benchmark application, personal records, and project transcripts are excluded.

Validation: 131 regression tests passed, no skips. An isolated installed-host fixture exercised bundle loading, the companion skill's own provider, native-to-PTC selection, real file/check execution, native permission denial, neighboring-preset isolation, guidance, and the version command. It used three fixed requests and zero inference-provider dispatches. The DSH market index passed the installed host's official format parser and is served over HTTPS without a redirect.

The smoke test uses an owned temporary workspace. Native Windows sandbox ACL requirements can still prevent PTC on other workspaces; this release does not bypass those controls. Cross-platform runtime behavior, performance gains, and behavior of other DSH preview versions remain unverified.

The community market index lists Flow Next and Ambitious Prompt using immutable Git source commits. It follows the official custom market format but is not an official curated catalog or endorsement.

Assets include a DSH bundle tarball, source ZIP, and SHA-256 checksums. MIT license. The original DeepSeek Harness MIT notice for the native preset snapshot is included under third-party/.
