apps/web browser e2e
English | 中文
These tests boot the real web composition in-process and drive it with a real
Chromium over real HTTP. The lane's mechanics — modes, fixtures, goldens, and
the deliberate composition divergences from dsh web — are documented in
scaffold.ts and the
browser e2e Agent Note.
These are Host-face tests
They type-check in the root tsconfig.host.json, not in the Client aggregate,
because they read Host services directly: ctx.apiProxy, the Host
SessionStore, ctx.sessionProjectionCache. Driving a browser at runtime does
not make a file part of the Client program — the two faces merge cordis
Context under the same keys with different services, so one program cannot see
both. Moving these files into the Client aggregate makes every Host-service
access fail to compile.
Do not import @deepseek-ai/dsh-client-* here
Importing a Client package — a value or a type — pulls its whole TypeScript
project, and every project it references, into the Host build graph. That has
bitten this lane once already: four Client consumer packages reference
api/remotes' Client face, which cannot compile until Host tsdown has generated
@deepseek-ai/dsh-goal/remote, so the Host build phase ended up waiting on an
artifact it produces itself.
When a scenario needs a Client-owned constant or pure function, mirror it here
instead, next to the commented-out import that names the source module. A drift
then surfaces as a missed selector or an unsuppressed notice — a loud failure,
never a silent pass. scaffold.ts holds the mirrored welcome-notice values and
exports them for the scenarios that assert on them.
Two kinds of Client import stand. assembled-boot.ts drives the shell itself, so
it imports AppWebEntry from @deepseek-ai/dsh-client-web and the boot-manifest
type from @deepseek-ai/dsh-client-modules/client: booting the real shell is what
that harness is for, and both packages are already in the Host graph. Separately,
the chat scenarios import conversationContextKey from
@deepseek-ai/dsh-client-runtime/client because client/runtime is reachable
through the unsplit directory-picker packages and pulls nothing further in.
That reachability is incidental, not a guarantee — if it ever leaves the graph,
mirror the helper like the rest.
Nothing mechanically enforces this rule; keep it in review.
