A reviewer found that `cancel(reason)` only preserved the caller's reason when
an active AbortController observed it (the mid-step path, via
`abort.signal.reason`). The marker-only windows (step-start at loop.ts and the
continuation gate) hardcoded `reason: 'cancelled'`, so the logged `turn/end`
reason was race-dependent on WHERE the cancel landed and the public
`cancel(reason?)` parameter was half-effective.
Capture the resolved reason (`reason ?? 'cancelled'`) on the agent when the
marker is armed, expose it on the LoopHandle as `cancelReason()`, and use it in
both marker branches so a turn dropped without a live controller records the
SAME `{kind:'aborted', reason}` the mid-step path produces.
The two existing window tests asserted `reason: 'cancelled'` while passing
`'from turn-start'` / `'from continuation'` — they documented the bug. Updated
both to assert the caller's reason (behavior + test changed together, per
AGENTS.md "tests document behavior, not golden truth").
Also fixes two stale docs the PR's contract change left behind: the
module-level ACP mapping comment and `codec.ts` both still said `session/cancel
-> agent.abort()`.

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.
