Two parity gaps with the JSONL backend found in review:
- append() now validates serializability and structuredClones the batch
synchronously at call time, BEFORE waiting behind the per-session
chain. A caller that mutates the passed array (or an event inside it)
after the call can no longer corrupt the persisted copy or advance the
cursor past what was written. Matches the JSONL backend.
- load() now computes the last-turn/end cut from the seq+type COLUMNS
only (cutAtLastTurnEnd is generic over {seq,type}); event `data` is
JSON-parsed only for the committed prefix, never for the uncommitted
tail. A malformed `data` in a crash tail is discarded, not treated as
unloadable — only a parse error/gap in the COMMITTED region is
unloadable (the SessionPersistence.load contract). Matches scanLog.
Regression tests for both.
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 humans, start with the development guide for local setup, hooks, environment variables, and quality gates, then read the architecture design before package work. Local context lives in packages/ and vendor/.
For agents, follow AGENTS.md.
