An aborted read can stay pending forever: undici drops the error when the abort lands on an in-flight response-body read (observed on the coverage lane's Node v24.13.0), and the stalled body of `llm-retry/tests/transport-recovery.spec.ts` then never settles. The idle watchdog delegated termination to the iterator observing its signal, so the request outlived its own deadline and the agent stayed `running` until Vitest's 90s budget; awaiting the abandoned request generator's `return()` queued behind that demand and would have re-hung the settled outcome. `idleWatchdog.next` now races its demand against its own deadline and rejects with the watchdog's TimeoutReason, so the deadline — not the transport — decides when an outstanding demand ends. Both adapters that consume the watchdog stop awaiting the abandoned generator's drain; the abort they already issue owns socket and SDK teardown. Evidence: instrumented stress harness at ~1s idle on Node v24.13.0 hung 4/160 iterations before this change (each with the abort delivered at ~1002ms and the underlying read never settling) and 0/160 after; Node v24.19.0 never hung. The new case in transport-recovery.spec.ts pins the behavior deterministically: it fails (times out) with the watchdog change alone and with no product change at all.

Summary
The harness is assembled from npm packages under packages/, grouped by capability family: sessions and the agent loop, model-facing tools, shell and filesystem execution, web access, subagents, and the rest. Use this page as the top-level map: find the owning group, then open its README for the package list. Every package is scoped @deepseek-ai/dsh-* and lives in exactly one group; each group README is the authoritative package map for its family.
Table of Contents
Package groups
Every package lives in exactly one group; new packages join existing groups, and a new group updates its own README and this table.

Release expectations
Most groups are product — stable API. The exceptions: experimental/ publishes without stability or support promises, and test-support/ and util/ are support with lower compatibility expectations.
Dependencies
The dependency graph is generated: docs/module-graph.md (pnpm run gen-module-graph, freshness-gated in CI).
Extension plugins depend on Service Definitions, never concrete providers. dsh-agent-loop is swappable; UI, hook, and tool plugins use dsh-agent. Composition bundles may depend on spine plugins. Capabilities separate Service Definition / Service Provider / Consumer roles when they evolve independently; see capability seams.
Package README contracts
Every package README covers purpose, configuration, extension points, and Model Experience unless the model-agnostic omission allowlist exempts it. It also carries ## Known Limitations and Deferred Work or uses its allowlist. Package conventions — exports, service access, tests — live in packages/AGENTS.md.
