Tianyi Cui a45bc8da67 fix(invariants): deepFreeze walks already-frozen objects' descendants
Session.append accepts event data from arbitrary plugins/tools, so a caller
can pass a SHALLOW-frozen object with mutable descendants. The old
Object.isFrozen early-return skipped such an object entirely, leaving its
descendants mutable in the log — exactly the history mutation ADR 0012 means
to catch. Now always descend, tracking visited objects in a WeakSet for
cycle-termination and idempotence. Addresses PR review finding.

DeepSeek Harness

Monorepo for the DeepSeek Harness group.

Projects

  • DeepSeek Code — DeepSeek's coding agent product.

Development

This monorepo is built on the Cordis framework (vendored as source under vendor/), microkernel-style: everything is a plugin.

yarn install
yarn test          # vitest
yarn demo:echo     # runnable echo-agent example (no API key needed)
yarn demo:coding   # the real DeepSeek coding agent (needs DEEPSEEK_API_KEY)

For agent instructions see AGENTS.md. For the architecture design see docs/architecture.md. Each subdirectory has its own README.md with local context: packages/, vendor/.
