Three corrections from review, none of which change behaviour. attemptStreaming promised output "as the command produces it", which spawnSync cannot do: it returns only after the child exits, and the two streams are echoed one after the other, so their interleaving is lost. For an npm publish that is visible — notices go to stderr while the `+ name@version` confirmation goes to stdout, so the confirmation prints first. The helper is now attemptEchoed and its contract says buffered, echoed after exit, stdout before stderr; live progress would need an asynchronous spawn with data listeners. The traversal comment claimed a node on the stack is a cycle only peer edges can form, and that skipping it drops just that edge. The cycle does carry a peer edge, because the install edges were proved acyclic a moment earlier, but the back edge that reaches the stacked node need not be the peer one — which is what the post-condition exists to catch, so the comment now points at it instead of asserting an invariant the traversal does not have. The `if (placed.has(member.name)) return` after leaving the stack was unreachable: a re-entrant visit returns at the top guard while the member is on the stack, so it can never be placed by the time the recursion unwinds.
DeepSeek Harness
English | 中文
DeepSeek Harness (dsh) is an open-source agent harness developed by DeepSeek AI.
It uses an architecture where everything is a plugin, and is powered by Cordis, whose design is described in A Programming Paradigm for Spatiotemporal Composability.
Developer preview
DeepSeek Harness is currently in developer preview and is iterating rapidly. THERE WILL BE COMPATIBILITY-BREAKING CHANGES.
