* fix(web): bind the right Sidebar before same-commit mount effects A plan review arriving while a global panel was active crashed its opener when the user returned: the frame mounts the Conversation column ahead of the right Sidebar seat, so PlanReviewOpen's mount effect called ctx.sidebarRight.openResource before the seat's passive bindService effect had published the binding. The slot runtime retired the crashed entry for the rest of the page, removing the View full plan link and every later automatic open. Publish the seat binding from a layout effect, which runs before any passive effect of the same commit regardless of tree order. The seat spec mounts a Conversation-column opener ahead of the seat and returns from a global panel; the plan-review Web scenario delivers a review while the Plugins panel is open and expects the preview and the link after the return. Both fail before the fix. * fix(web): open the plan review once the Sidebar seat is mounted Replace the layout-effect binding with an observable: ctx.sidebarRight.mounted publishes the session whose seat is on screen, undefined while a global panel replaces the Conversation. The seat keeps binding from its passive effect. PlanReviewOpen reads the source through a bound hook and opens once a seat is defined, so a review mounting ahead of the seat in the same commit no longer assumes a bound seat and never crashes its entry. The seat spec's opener stand-in now reads `mounted` the way a slot component does; the service spec pins that only real transitions publish, and the PlanReviewOpen spec covers a review that mounts before any seat and opens once the seat binds. * test(web): align the plan-review console tripwires and the seat term The off-screen review case now asserts the reconnect warnings like its siblings and filters crash logs by error level as the other e2e files do. The zh README keeps 席位 for the seat throughout. * test(plan): keep the review props cast at its baseline fingerprint verify-no-unknown-casts counts a modified assertion as new. The two PlanReviewOpen specs now share the unchanged baseline cast through one helper and supply the seat hook as a typed value beside it.

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

Release expectations
Most groups are product — stable API. The exceptions: experimental/ publishes without stability or support promises, and test-support/, runtime-diagnostics/, 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, invariants, tests — live in packages/AGENTS.md.
