DeepSeek Harness Architecture: Cordis, Profiles & Plugins
DeepSeek Harness composes an empty Cordis root from ordered bundle patches, the profile patch, a home-level patch and command-line overlays. Later layers win by row, and a patch replaces a targeted row’s complete config rather than deep-merging arbitrary keys. This page separates verified behavior from community reports and marks the release-candidate context so you can act without mistaking an observation for a permanent guarantee.

What is verified now
DeepSeek Harness composes an empty Cordis root from ordered bundle patches, the profile patch, a home-level patch and command-line overlays. Later layers win by row, and a patch replaces a targeted row’s complete config rather than deep-merging arbitrary keys.
Evidence basis: Official architecture/reference docs. The status was checked on 14 August 2026; re-check the linked source after any dsh release.
Safe workflow
Use the smallest reversible workflow first. Do not add community plugins or paste credentials while validating the base behavior.
- Inspect the default bundle layers.
- Dump the composed configuration before boot.
- Add one patch overlay and verify which complete config row wins.
Verify before moving on
A successful result should be observable: a version string, reachable local URL, valid provider response, loaded configuration, or disappearance of the exact error. If the result differs, stop and capture sanitized evidence rather than stacking unrelated fixes.
- Record the exact dsh, Node or Python version.
- State the operating system and installation method.
- Link the first-party source and include only sanitized logs.
