`USER_PRESET_DIR` was exported with no production consumer — only the new test
read it, and a test that imports the implementation constant cannot catch that
constant being wrong. It stays module-internal, and the test spells the segment
it expects.
Overlaps master on the preset e2e, the web scaffold, and the generated
config-catalog triplet; all merged textually, so the catalog is regenerated and
its pairing hashes re-recorded rather than trusted.
A test file under packages/client now says which face it covers:
`*.client.spec.{ts,tsx}` and its `*.client.{ts,tsx}` helpers belong to the
Client aggregate, `*.host.spec.ts` to the host aggregate. The carrier's four
node-half specs take the Host suffix.
The two suffixes are mutually exclusive, so each aggregate excludes the
other's and both keep one broad test glob: `exclude` wins over `include`, and
`packages/client/**` no longer has to be excluded wholesale from the host
program with per-file `files` entries carved back out of it. A Host-face spec
that reaches only Host source therefore needs no cross-face project
reference, which the split-project rule rejects.
vitest still discovers every file through `**/*.spec.{ts,tsx}`.
Every generated method resolves to RemoteResult, so the plain-Node script
must read the business value through `.value`: the CAS ref it passed on to
goals/edit was undefined, which the client codec rejected before the request
left. The invalid-payload case keeps its try/catch — a codec-rejected
argument still throws at the Client Remote face rather than folding into the
error branch.
Review follow-ups that are logic rather than documentation:
- rpc.schema.ts had lost the credential-rejected branch while api-proxy.ts
still returns that code, so a legitimate business error failed the
client's response parse. Restore the branch and assert it.
- rpc-schemas.spec.ts had lost the workspace list, archiveSession and
insertSessionBefore cases along with the command schemas; those routes
still ship, so restore their coverage.
- An omitted SRC field is now recognized by an absent key instead of an
undefined value, which makes the allowance assertExactArguments already
granted reachable; an explicitly undefined field stays invalid input. A
weak descriptor's undefined result rides the wire as an absent value,
matching the envelope removal.
- The chooser unmounts an already-created backend when the surface entry
fails to load, and no longer reverses the captured id array in place.
`command.execute` no longer exists on the API Proxy, and the fake's own
handler went with it, so the case only reached a 404 body. The same carrier
behaviour is asserted on live routes by its `session.search`,
`subagent.prompt` and `host.pickDirectory` siblings.
Matching the full `RemoteFailure` keeps the assertion inside the typed result
and drops the `expect.stringContaining` placeholders, whose `any` return the
lint rule rejects on assignment.
`@deepseek-ai/cordis` returns to the peer and dev dependencies of
`dsh-client-ui-model` and `dsh-client-ui-skill`; every harness package declares
it, and the client type-assembly rename dropped it from both. The commands
manifest ships `src` alongside its generated typert faces, matching the
`./src/*` export it already declares.
knip gains the two directory-picker surface workspaces, whose specs are `.tsx`
and matched no default pattern, and ignores `zod` in the commands workspace:
that dependency belongs to the generated Remote and Host faces in `lib/`, which
knip never scans. The unused `dsh-client-test-runtime` and
`dsh-client-connection` dev dependencies are gone; the picker surface's own spec
never imported the former, and ui-settings reads the carrier's types through the
Remote assembly now.
Exporting `./typert` and `./remote` ships two generated modules that
`import { z } from 'zod'`, and the package declared no runtime dependency at
all. Under pnpm's isolated layout nothing resolves zod for it — there is no
root `node_modules/zod` to walk up to — so loading the plugin tree failed with
ERR_MODULE_NOT_FOUND the moment a composition mounted the commands typert
face. The two other packages exporting `./typert` both declare it; this
matches them.
Every generated Remote method resolves to `RemoteResult<T>`, so the Gateway
client spec asserts the ok and error branches instead of the unwrapped value
and a throw, and the generator fixtures declare the wrapper in the consumer
face they typecheck. The RPC-failure test splits into the Host error carried
verbatim in the error branch plus a transport throw folded into it.
The runtime client, ui-command and ui-plan benches answer the generated
commands Remote through its result branches and provide the `remote.commands`
namespace their plugins now inject; the ui-command bench also serves the `$on`
the service subscribes on construction.
The directory-picker chooser mounts a backend and its surface as a pair, so the
real-Loader composition serves both surface packages and asserts each entry
arrives and leaves with its backend.
The Gateway client spec's synthetic Remote namespace now resolves under both
analyzers, so its typescript/no-unsafe-call suppressions report as unused.
A business package imported the Remote assembly for `ctx.remote` and the
Connection plugin for the wire types it passes around. The assembly now
re-exports the carrier's Client-facing types, so a business package names one
package. The re-export is type-only: the carrier's runtime values keep their
own module edge, since inlining them here would duplicate the carrier inside
the assembly bundle.
Four surfaces that had no Remote assembly dependency declare one now.
The Gateway and the carrier each compiled both halves under one tsconfig, so
the Host aggregate built their browser faces — including the face that owns
`ctx.remote`, the most likely future consumer of a generated `/remote`
contribution. Both packages now expose a host and a client face, and each
aggregate references only its own; three modules the halves share appear in
both file lists, as api/remotes already does.
The two apps/web specs in the Host aggregate restate the conversation engine's
Context key format instead of importing the Client runtime for it. A drift
makes the key miss its rendered node, so the assertion fails loudly.
The Host aggregate now reaches one Client project, the carrier's host face,
which the Gateway's own dispatch face needs; no generated contribution is
reachable from it.
The browse and native backends were dual-face packages: a Node backend plus a
browser surface under one tsconfig that referenced Client packages. That put
Client projects — and through them the Client runtime — inside the Host
compiler aggregate, which builds before the generated Remote contributions
exist. Each browser half moves to its own Client package, and both backends
become Node-only.
The interaction is still one choice: the adaptive chooser mounts the backend
and its surface as a pair of Loader entries and tears both down in reverse, so
a resolved kind still swaps both faces. Compositions that pin an interaction
directly now pin the pair, and the chooser's runtime-string package list keeps
naming everything a composing app must resolve.
`CommandService.list` and `execute` carry the wire contract directly through
`@Remote`, and the Client assembly mounts the generated commands
contribution. The legacy API Proxy route, its schemas, the map rows, the
generated client methods and the fixture's command domain are removed, so the
catalog and the admission call have one owner again.
`Session.command()` keeps a result-shaped public face for parity with the
prompt, cancel and attachment neighbours it sits beside, and reads the
generated namespace through one `SessionRemotes` parameter. The Session
cluster declares that face against the owning business package rather than the
generated contribution: the Host compiler aggregate builds this package, and
it runs before any contribution is emitted.
Migrated calls lose the `title-invalid` class of protocol-only error codes and
report `internal`; no production caller branched on them.
Every generated Remote method now resolves to `RemoteResult<T>`: the Client
face folds a carrier failure, a transport throw and a rejected result payload
into one error branch, so no consumer wraps a call to recover them. Only
assembly faults still reject — a wrong argument count, an unmounted method, a
missing Context binder, an absent Connection.
`RemoteFailure.code` stays an open string because the closed RPC code union
lives in the carrier package, which already depends on type-meta; naming it
here would invert that edge.
The goal surface drops its own try/catch plus the structural probe that
guessed whether a thrown cause was an RPC failure, and reads the result
instead.
Absence crosses the wire as a missing field: an omitted argument and a void
or undefined result both arrive as an absent JSON member, and the wide RPC
result slot accepts a success response without a value. Parameters declared
optional stay optional in the generated consumer declaration, so a business
signature is never widened to `T | undefined` to suit the wire. The weak SRC
descriptor reads parameter names from a JavaScript signature and cannot see
optionality, so a source-launched Host accepts an absent field and the strict
LIB pass owns rejecting a genuinely missing required parameter.
Adding COLLAPSE_SECTION_ORDER and CODE_ONLY_INSTRUCTION shifted every
later line in packages/core/tools/src/index.ts by 14, and three generated
artifacts cite those lines: the subsystems cordis-surface region, the
event producer/consumer matrix, and the Agent Note pair record left
inconsistent by the cherry-pick resolution.
`collapses()` read `defaultMode`, so the collapse only applied when the
DEPLOYMENT was `code`. An agent handed `code` by an agent preset under a
native default announced `[run_code]` on the wire and still executed a
model-direct native call -- the bypass this collapse exists to close,
reopened for exactly the composition `dsh-agent-tool-mode` produces.
`modeFor(scope)` is the same resolution `wireSchemas` and the SDK section
already use, so presentation and execution cannot disagree, and a mode
inherited from a standing preset scope collapses like a declared one.
The per-agent and preset tests asserted only the wire, which is why the
regression passed them. They now assert through the executor: the body
never runs, the call resolves UNKNOWN_TOOL, and the native sibling beside
it still executes.
The executor collapse landed without telling the model it exists. Every
tool contributes its own guidance section naming its tool, none of them
qualify how that tool is reached, and they all render before the SDK
(orders 100-199 against SDK_SECTION_ORDER 150), so the prompt said "Use
the read tool" eleven times and never said only run_code is callable.
A real session shows the consequence: the model emitted a native call,
read `unknown tool "read"` for a tool the same prompt declares, and
concluded the deployment was inconsistent rather than routing through
run_code.
The registry now contributes `tools:code-only` at order 99 -- ahead of
the guidance band -- stating the rule, registered wherever `tools:sdk`
is and rendering empty outside an effective `code`. `both` renders it
empty because its native calls do execute, which is also why
both-mode-turn no longer shares code-mode-turn's expected prompt. The
denial itself now names the route back, since a bare UNKNOWN_TOOL for a
declared tool is what misled the model.
