P1: both merge parents shipped SCHEMA_VERSION=3 for different layouts (surface columns vs seed_length), so an on-disk 3 was ambiguous and wrongly accepted. Bump to 4 (merged layout) so the version check rejects both sibling v3s. P2: a surface-eligible event with no surfaceOp lands in the log but vanishes from deriveMessages() (surface is the sole derivation path). The typed append overload enforces the marker only when the type arg is a literal; it collapses to optional when widened to the union (a caller iterating raw events). Guard at runtime in both append() and the seed constructor — no backward-compat for surface-less logs. Shared seed fixtures carry surfaceOp explicitly and the appendLog helper forwards it verbatim (no synthesized default). Exports isSurfaceEligibleType. Regression tests for all three, each verified to fail on the unfixed code. Gates: typecheck, test (1115), snapshot (14), doc-sync, lint, build, hygiene green.
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.
pnpm install
pnpm run test # vitest
pnpm run demo:echo # runnable echo-agent example (no API key needed)
pnpm run 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.
