Second alignment step for #2248: document-level drag intake behind the new
DropOverlay atom, lightbox close icon and shared dialog mask, DeepSeek Chat
thumbnail rules (single 240px long edge with ratio clamp, 64px tiles, merged
consecutive assistant images), image limits raised to 20/10MiB/100MiB and
published to clients as the imageLimits projection, whole-batch intake
pre-check with product-copy banners, and attachment-error reasons mapped to
localized copy.
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.
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 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.
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.
#2201 landed three moves this branch sits on top of. `bindSettingsScope` became
`ctx.settingsScope.bind` on the Settings surface, so the section injects that
service and the Remote face instead of importing a free function; the
`SettingsScope` types moved into the runtime contract module, which is where
this branch's `base`, `user`, and `unset` now live; and the client
`credentials/changed` event became the forwarded owner event
`credentials/updated`, which the web-search card subscribes to through
`ctx.remote.$on`.
The generated module graph crossed mermaid's 1000-edge render guard with this
branch's 14 new edges. The guard doubles again, exactly as it did at 500 — the
graph counts real package edges, and trimming them to fit a renderer default
would make the document lie about the dependency set.
apps/web/tests/README.md records why these e2e type-check in the Host aggregate
and why importing a Client package there pulls its project tree into the Host
build graph, with mirroring as the standing answer. The Agent Note drops the
directory-picker face split (assessed and declined) and the grep-level gate in
favour of that README.
docs: regenerate the catalogs and retarget the moved declarations
The forwarded-event change moved three owner packages' cordis `Events`
declarations and their branded types into client-safe `./types` modules, and
the settings-scope split moves the shell spec into ui-settings-general. Point
the type-equivalence manifest and the affected Agent Note at those homes,
register the new `remote/*` event scope and the `ctx.settingsScope` service in
the catalog partition, and re-run the generators.
`$on` joins the documented `TypeRTClientRemote` surface, and the two Agent Note
fences that quote a bare member signature are marked `ignore-check`: they are
declaration fragments, not compilable units.
refactor(client): make ui-settings the settings domain's base layer
The settings-namespace transport lived in client/runtime, where every feature
could value-import it because runtime is a platform module. It belongs to the
settings domain, but moving it into ui-settings as a shared function fails
twice: the client bundle purity gate forbids cross-plugin value imports, and
ui-settings reached ui-sidebar for its shell, so any feature depending on it
closed a cycle through ui-layout and ui-theme.
Both halves move. `ctx.settingsScope` is now a cordis service — the
collaboration shape the purity gate prescribes, and the service proxy binds
`this.ctx` to the caller, so a bound scope's disposer belongs to the calling
fiber. The shell ui-settings used to own (the `sidebar.settings` occupant, its
navigation, and the nav-row projection) moves to ui-settings-general, which
already owns the chrome and the General section. What stays in ui-settings is
what carries no `ui-*` dependency: the scope service and the canonical settings
slot types, `settings.general.item` included. That type was parked in the locale
package precisely because the declarer was unreachable without a cycle; every
registrant now depends on this base layer, so it comes home.
The scope CONTRACT stays in client/runtime: a feature service accepts a scope
through its own signature without depending on the surface that binds it.
The forwarded settings invalidation replaces the deleted client-side
`settings/changed` event, so the transport reads `ctx.remote.$on`. It reaches
`$on` through the gateway's Client half plus the allowlist's type-only subpath
rather than api-remotes' Client face: that face imports a Host-tsdown-generated
artifact, and this package is reachable from the Host build graph through its
callers.
refactor(client): reach the settings transport through ctx.settingsScope
Every feature that owns a preference row switches from value-importing a shared
binder to the settings domain's service, and declares the two injections that
binding needs: `settingsScope` for the transport and `remote` for the forwarded
invalidation it subscribes to on the caller's own context.
The rows stay with the features that own the preferences — Language with locale,
Appearance with ui-theme, Composer Enter with ui-conversation. Only their route
to the transport changes, so no settings surface moves and no feature gains a
dependency on the shell.
The `settings.general.item` slot type now arrives from ui-settings, the base
layer every registrant already depends on, which retires the re-export outlet
ui-theme kept and the parked declaration in the locale package.
client/runtime drops its settings-form and schemastery dependencies with the
transport that used them.
test(client): bind the settings transport in the specs that boot a preference row
Every bench that activates a plugin owning a preference row now supplies the two
services that plugin injects: the forwarded-event port and the scope service.
Specs that exercise no settings path get the minimal doubles; the ones that do
drive their refresh chains through `remote/host-event`, the same signal
client/runtime republishes from a forwarded frame, replacing the deleted
client-side `settings/changed` event.
Also fixes a publication defect the built-invariant gate catches once it runs:
api-remotes' invariant companion shared the allowlist module with the package
index, so rolldown hoisted it into a third chunk beside the two bundled entries
— a file the mechanically derived publication list does not carry, leaving an
installed companion unable to import it. The companion now reads the allowlist
through this package's own published `./types` subpath, which the bundle keeps
external, so each entry stays self-contained.
The dynamic-subscription cast in apiproxy is gone: after the vendored cordis
rescope, `on` accepts the rest-parameter handler directly, and the allowlist's
shape assertion still carries the safety argument.
fix(client): carry the settings-scope move across the release manifests
Rebasing onto the publishable release set replaced every manifest's dependency
block, so the packages this change touches restate their additions in the
workspace-protocol form: the base layer's own transport dependencies, and the
`ui-settings` plus `remote` edges each preference-row owner now needs.
ui-settings-general takes clsx with the shell it received, and client/runtime
drops the settings-form and schemastery dependencies that left with the
transport.
fix(api-gateway): give each $on subscription its own registration and containment
Two defects in the forwarded-event subscription table, both raised in review:
A set keyed on listener identity stored one entry when two callers subscribed the
same function object to the same event, so the first frame reached it once instead
of twice and either disposer silenced the surviving registration. Subscriptions are
now records addressed by registration, which is what "the disposer belongs to the
calling fiber" requires.
A listener declared void may still be `async`, and the synchronous `try/catch`
could not see its rejection: the promise was dropped and surfaced as an unhandled
rejection outside the documented containment. Delivery now attaches a rejection
handler when a listener returns a promise, so both failure modes are logged and
isolated alike.
Delivery also iterates a snapshot, so a listener that subscribes or disposes during
a frame no longer changes who receives that frame, and production matches the
TestRemote double instead of relying on live Set iteration order.
Both fixes are pinned by tests that fail against the previous implementation. The
double gains its own spec for the `$mount` refusal and the unsubscribed-name drop —
per-file coverage reaches it — plus a note that it propagates a throwing listener
where production contains one, so no spec mistakes it for the containment guarantee.
Three prose corrections: `assertJsonArgs` states where its throw actually surfaces
(the emitter's listener containment, not load or emit time), the browser e2e README
names every standing Client import rather than claiming one exception, and two
comments and a test title state the forwarded event instead of the deleted
client-side one.
refactor(remote): deliver forwarded frames through ctx.remote.$dispatch
The carrier used to relay each decoded frame over an internal
`remote/host-event` cordis event so the delivery port could stay off the Remote
contract. The relay was the wrong shape twice over: it put a client-face event
into a scan whose subject is the Host vocabulary, forcing a walk exemption for
something that is not a Host event at all, and it made a direct handoff between
two Client plugins look like a broadcast any plugin participates in.
`TypeRTClientRemote` now carries both roles of one surface — consumers subscribe
with `$on`, and whoever owns the Host frame sink hands frames over with
`$dispatch` — so client/runtime calls the Remote service directly and the event
declaration is gone. A cordis service method is the collaboration shape the
client bundle purity gate prescribes, and it needs no relay to satisfy it.
The trade is that the handoff is now developer-visible: any plugin holding
`ctx.remote` can synthesize a forwarded event. That is the exposure the relay
already had — `ctx.emit` was equally reachable — stated in the contract instead
of hidden behind a private subscriber.
runtime reaches `ctx.remote` through the gateway's Client face rather than
api-remotes': that face imports a Host-tsdown-generated artifact, and this
project sits in the Host build graph.
refactor(api-remotes): keep the allowlist value out of types.ts
`src/types.ts` carries only types by package convention, but it held the
forwarded-event array, so the type-only subpath published runtime code. The
array moves to `src/remote-events.ts` and `types.ts` derives its projection from
it; both compiler faces list both files, so the Host forwarding loop and the
consumer key face still read one declaration and the package's exports are
unchanged.
The invariant companion returns to an empty installer. Its dispatch-shape check
was the only reason the companion imported the allowlist, which made the two
bundled entries share a module: rolldown hoisted it into a third chunk that the
mechanically derived publication list does not carry, so an installed companion
could not import it. Dropping the check retires that coupling along with the
subpath-import and bundle-external workarounds it needed, and the shape the
check enforced at runtime is the part the Host face's `TypeRTForwardableEvent`
assertion already refuses at compile time.
test(ui-task): bind the locale plugin's new injections in its bench
The bench boots the real locale plugin, which now injects the settings-scope
service and the forwarded-event port, so it stayed pending and left `ctx.locale`
undefined. Supplies both doubles like the other benches that boot a plugin
owning a preference row.
docs: close the documentation gates for the forwarded-event surface
Regenerates the two graph catalogs and re-records every bilingual pair this
branch edited. Several pairs needed real work beyond the record:
- The generators write only the English side, so the Chinese sides of
`event-producer-consumer` and `module-graph` had drifted: the former still
listed the three deleted client-face events and pointed at declaration sites
this branch moved into `types.ts` modules, and the latter carried a stale
dependency graph.
- `TypeRTClientRemote`'s documented declaration gains `$dispatch` on both sides.
- The pairing contract requires both sides to link the same target, so the
apiproxy README and the design note now link the English note from both
languages, and the note's code blocks are byte-identical across the pair
(a translated comment inside a fence counts as divergence).
- `apps/web/tests/README.md` gains its Chinese counterpart; the browser e2e lane
documents a discipline reviewers apply, so it belongs in the bilingual corpus
rather than in the pairing exemption list.
- Four fences in the design note are marked `ignore-check`: each quotes a member
signature, a union arm, or a snippet that names symbols it does not import, so
none is a compilable unit.
docs(agent-note): transition the forwarded-event note to implemented
The design shipped in this PR, so the pair moves into `implemented/` and takes
that folder's skeleton: `## Proposal` becomes a present-tense `## Decision`,
and `## Acceptance criteria` plus `## Risks` fold into `## Verification` (what
pins the behavior) and `## Consequences` (what the shipped shape costs).
Facts that moved after the proposal are corrected rather than preserved: the
allowlist value now lives in `remote-events.ts` beside a type-only `types.ts`,
the delivery port is `$dispatch` rather than an internal cordis event, and the
invariant companion is an explained empty installer. `Verification` states the
two `$on` defects the review found — independent registration identity and
async-rejection containment — since those are now the properties tests pin.
Supersession is partial, so five active notes stay active and gain a
cross-link each: `web-config-plane`, `web-client-session-scope`,
`config-plane-boundaries`, `versioned-gui-welcome-onboarding`, and
`permission-default-for-new-sessions` each described a frame this change
replaced. Only the mechanism sentence is annotated; every conclusion those
notes own is untouched, and `host/models-changed` remains apiproxy's own
derived frame in all of them.
Also pins the disposer's idempotence: calling one `$on` disposer twice must not
splice a surviving twin registration out from under its owner.
fix: docs
fix: test
api/remotes owns the allowlist and its type projection; type-meta owns the shape
predicate, the selection seat, and the internal remote/host-event carrier
signal; api/gateway's Client half turns that signal into $on callbacks through a
private dispatch. apiproxy forwards each allowlisted emission verbatim in one
host/remote-event frame, registered ahead of the derived invalidation frames so
frame order is unchanged, and drops the three per-event variants it replaces.
Owner packages move their Events declarations into client-safe ./types exports,
so a consumer's listener signature is the Host's own declaration.
Each owner package's README states which of its cordis events are forwarded and
that the declaration now lives in the client-safe ./types export. api/remotes
documents the allowlist as the single control point and the deliberate
both-faces listing of src/types.ts; development.md keeps the split-tsconfig rule
current.
Three seams: the tsconfig path map gained a mapping on each side and keeps
both; the event-producer matrix is generated, so it was regenerated rather
than hand-merged row by row.
ApiProxyDefaults uses an exact optional property, so passing config.sessionExportCompressionLevel directly made the service object carry an explicit undefined that is not assignable to the resolved request shape. The full host build caught this distinction after the redundant fallback was removed.\n\nConditionally omit the property when Cordis has not supplied a value. Direct createApiProxy callers still receive the implementation-owned default, while configured plugin values pass through without introducing another defaulting site.
Response-consumer cancellation already stopped lineage reads, persistence reads, and ZIP production, but the final attachment phase called readImage without the producer signal. A slow or stalled attachment backend could therefore keep working after the browser abandoned the download and prevent the producer from settling.\n\nExtend the attachment read seam with optional cancellation, forward it through the local backend into Node's filesystem read, and preserve the abort reason rather than wrapping it as a storage failure. The exporter now passes its combined request/consumer signal to every attachment read.\n\nCover both ownership boundaries: the local-store test proves filesystem forwarding and cancellation identity, while the assembled export test cancels a reader during a pending attachment provider call. Regenerate the Cordis API catalog and paired documentation so implementers can rely on the new contract.
The response stream uses a fixed 64 KiB byte high-water mark; no deployment setting controls it. Calling that queue configured incorrectly suggested another tuning surface and obscured the concrete memory bound.\n\nName the fixed capacity directly while preserving the separate bound of one synchronous fflate push beyond the queued bytes.
The pre-stream error boundary covers both the live-session flush barrier and the persistence read, but its response attributed every failure to reading storage. A flush failure therefore produced a misleading diagnostic even though the response correctly withheld private backend details.\n\nUse preparation as the shared operation name and cover the flush-failure path explicitly. Both preparation stages now retain one stable, path-safe HTTP 500 without pretending to identify the failing stage.
The Cordis schema supplies the normal plugin default, while createApiProxy also owns the fallback required by direct programmatic callers. Repeating the same nullish fallback in ApiProxyService created a third defaulting site without adding a distinct invariant.\n\nPass the validated config value through unchanged and leave createApiProxy as the single implementation boundary that turns an optional request value into the required compression specification.
Session-log ZIP entries always used DEFLATE level 6 even though compression level is a deployment tradeoff: CPU-constrained hosts may prefer low latency while bandwidth-constrained hosts may prefer smaller archives. A hardcoded level also violated the repository rule that deployment-varying plugin choices live in validated Config.
Add sessionExportCompressionLevel to ApiProxyService.Config as an integer 0-9 with default 6, resolve the same default once for direct createApiProxy callers, and pass the required level into the streaming module. Tests prove schema defaulting and rejection as well as a level-0 versus level-9 archive-size difference with identical extracted content. The generated config catalog, bilingual gateway README, and feature note document the knob and its tradeoff.
The ZIP loop checked desiredSize only after a push and responded to an overfull queue with setTimeout(0). A timer turn does not mean the consumer drained anything, so a slow or disconnected client still allowed the producer to enqueue the complete compressed archive while later artifact and attachment reads ran eagerly.
Give the ReadableStream a 64 KiB byte queuing strategy and block the single producer on a pull-released capacity gate whenever desiredSize is non-positive. Cancellation wakes that gate through the existing producer signal; synchronous fflate output is therefore bounded to the queue high-water mark plus one input push. A regression test exhausts timer turns without consuming and proves the next media entry remains unread until response pulling begins, and the bilingual contracts now describe the real bound.
Only the root raw-artifact read received the request signal. Lineage discovery and descendant reads could continue after disconnect, response-body cancellation did not stop the producer, and the root error boundary converted an abort rejection into an ordinary HTTP 500.
Combine request and response-consumer cancellation into the ZIP producer signal, forward it through every cancellable read, check it around the attachment seam, and terminate fflate exactly once when production stops. The pre-stream boundary now rethrows the original abort instead of translating it. Regression tests cover signal propagation, exact cancellation identity at the HTTP boundary, and a reader cancellation interrupting an in-flight descendant read; the bilingual host contract records these lifecycle semantics.
The exporter read persistence artifacts directly even when the requested root or a descendant was still live. Buffered session events could therefore be omitted from a successful download, so the advertised verbatim-artifact guarantee described storage accurately but captured an arbitrarily stale durability boundary.
Resolve each id against SessionStore and cross its authoritative flush barrier immediately before readRaw. Cold sessions remain a no-op, while live roots and descendants are made durable independently; this intentionally yields a per-session read-boundary snapshot rather than claiming an atomic lineage snapshot. A host-path regression test proves both artifacts change from stale to durable only through flush, and the bilingual host contract and Agent Note document the boundary.
