parseRelayFrame parsed the wire text for the lifecycle snapshot and again for the envelope, and unsupportedFrameRefusal repeated both parses. One JSON.parse now feeds the snapshot check, the envelope, and the refusal branch, so the hot path decodes each frame exactly once.

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
Product groups have maintained product roles, while their public APIs remain pre-stable. Experimental status is independent of publication, installation, and optional delivery. Nonexperimental runtime packages must have product use or an explicit package classification; SDK, build, test, and declaration infrastructure have separate classifications.
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.
