Yichen Jiang b239db6aeb test(net): assert the proxy-name contract on a platform that folds case
The Windows coverage lane failed on four cases that assume `http_proxy` and
`HTTP_PROXY` are separate variables. They are one variable there: `process.env`
is case-insensitive, and the launch snapshot folds names for the same reason. A
scenario built on "the user set only the lowercase name" cannot exist.

Two of them assert a contract rather than a spelling, so they now hold either
way: what reaches a child for a scheme the user named is the user's own value
and never the derived one, and a nested install carries the active policy's
value rather than the outer install's published one. Both read over the pair of
names instead of one.

The other two are about the case distinction itself. Neither can hold on a
folded environment, so each asserts what that platform does instead of skipping:
the later entry wins where a preference cannot be expressed, and a diagnostic
names the spelling resolution asked for. Both were verified against the folding
arm rather than reasoned about.

The DeepSeek Harness package workspace: how the npm packages under packages/ are grouped, what each group owns, and the conventions that bind them. package-group

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.

Group Role
core/ Product API spine: sessions, prompts, tools, agent services, and the concrete loop
api/ Remote BFF assembly and Typert RPC gateway
typert/ Type graph generation, artifact loading, and runtime registry
goal/ Same-session goal persistence and lifecycle
schedule/ Session-local scheduled follow-ups
feedback/ Human feedback capture and command
identity/ Shared anonymous identity
llm/ LLM capability family: abstract service + provider adapters
e2b/ E2B remote-runtime providers
subprocess/ Subprocess capability family: Service Definition + local process-tree provider
shell/ Bash capability family: executor seam, local impl, model-facing tools
terminal/ Persistent PTY capability family: owner-scoped sessions, local implementation, model-facing tools
code-runtime/ Code-execution capability family: Service Definition + worker-thread provider + PTC mode Consumer
sandbox/ Process-confinement seam; bwrap/Landlock/Seatbelt backends
fs/ Filesystem capability family: seam, local impl, model-facing file tools, discovery tools
lsp/ LSP capability family: seam, generic stdio provider, and the lsp tool
skill/ Skill capability family: provider registry, local provider, model-facing catalog/loader
compaction/ Compaction capability family: Service Definition + basic provider + command Consumer
context/ Model-visible request context: workspace instructions, time context, references
subagent/ Subagent capability family: provider-registry contract and model-facing delegation tools
jobs/ Generic background-job runtime and model-facing job control tools
experimental/ Private prototypes and internal-only plugins
workflow/ Workflow seam, worker-thread engine, and model-facing workflow/ralph tools
webhook/ Verified external events, trusted rules, and fire-and-forget Workspace Sessions
web/ Web capability family: seam, search/fetch providers, model-facing web tools
net/ Process-wide outbound transport policy: the HTTP proxy every request inherits
attachment/ Durable attachment identity, validation, local content-addressed storage
spill/ Spill capability family: storage seam, local impl, tool-result spill policy
todo/ The model-facing todo_write tool
plan/ Plan collaboration state with a direct entry command and reviewed exit
preset/ Per-session agent composition from preset cordis.yml files
guard/ Loop-hygiene guards: advisory repeat-call reminders + the tools/execute deadline enforcer
bundle/ Installable dsh --profile patch layers
extensions/ Agent runtime self-modification: live plugin/service inspection and model-written mount/unmount
hooks/ Hook bridges + the shared Claude Code / Codex wire-protocol library
session/ Durable session data plane: persistence seam + backends, projection seam, log-backed titles, session reporting
session-query/ Session retrieval family: logical corpus, bounded reads, lineage, semantic filtering, SQLite full-text search
settings/ User-settings seam + file-backed provider
credentials/ Credential-reference and credential-record seam + env-over-.env provider + authorization flows that ask a human
storage/ Non-session storage hub + backends + domain form
workspace/ Workspace entity
sdk/ Out-of-process SDK: JSON-RPC protocol and TypeScript client/server
acp/ Automation-only Agent Client Protocol server
interaction/ Human-collaboration plane: approval/interaction seams, permission preset, commands, ask-user tool
boot/ Shared app-bin boot glue
host/ Web-GUI host half: API gateway + HTTP route server
client/ Web-GUI browser half: shell, wire, object services, slots, ui-* plugins
examples/ Reusable composition bundles for tests and custom deployments
test-support/ Support infrastructure (testkits, invariants, replay, Loader smokes)
runtime-diagnostics/ Runtime diagnostics: package-owned invariant checks and reports
util/ Low-level zero-dependency utilities shared across groups (Branded<B>, home/path helpers, timeout, retention)

Release expectations

Most groups are product — stable API. The exceptions: e2b/ is a POC, experimental/ is unreleased, and examples/, 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, including dsh-agent-spine-demo, 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.
