React half of the session-projection client base: the renderer contract gains
an open-key projections face on SessionMaybeProvideInfo (cellOf(key), distinct
from the static hooks roster), web-react mints projectionHook (per-bundle cache;
per-cell uSES binding via the shared observableHook cache; unresolved keys read
undefined through the absent source so hook order stays constant), standardKit
delivers kit.useProjection, and the runtime merges UseProjection into
SessionStandardProps/SessionMaybeStandardProps (overloads mirror useSession).
3 jsdom specs (kit delivery + live re-render, selector over undefined, faceless
bundle = all absent); existing direct-prop-feed specs gain the one-line stub the
new required seat mandates.
Object layer of the session-projection RFC client base: ProjectionCellSpec/
ProjectionCell/ProjectionCellSet with the single seq-watermark rule (live and
window-replace events share one filter; baseline reset re-seeds value+watermark
unless a newer commit applied; absent key = capability absent), Session
dispatch at appendLive/installWindow (projections block read structurally,
TODO(gui) switch to the interface package), SessionsService.registerProjectionCell
roster (live scopes now + future scopes at mint; disposer sweeps every session),
and the provideInfo projections face (key-addressed bare cell sources).
15 object-layer specs: watermark no-rollback, late-baseline seq rule,
capability absence, schema-failure degrade, duplicate-key throw, resync e2e.
Hand fixes for the findings --fix cannot touch, mirroring the fixes
already applied on the fe-docs feature branch (same file, same shape)
so its eventual rebase resolves cleanly:
- restore the return the no-confusing-void-expression autofix ate in
useAbsentSnapshot (typed S | undefined; hook call kept for hook-order
stability, undefined returned explicitly);
- re-type DOM queries the no-unnecessary-type-assertion autofix broke:
getByRole<HTMLButtonElement>(...) generics instead of the removed
as-casts (the eslint program and the client tsconfig aggregate
disagree about these casts; the generic form satisfies both);
- justified eslint-disable for the deliberate legacy paths: keyCode 229
IME-composition detection, execCommand clipboard fallbacks, lib.dom
clipboard optionality, and the any-typed Reflect.get/this probes in
test fakes;
- drop the dead react/no-danger directive (eslint-plugin-react is not
loaded, so the rule never applied) keeping its shiki rationale;
- delete the tautological 'Z' comparison and the renameTarget null
check already implied by renameBlocked;
- css-module non-null assertions replaced by type widening
(Button className, TAG_CLASS Record) per the established pattern;
- misc: max-len comment wraps, void generic drop in the deferred test
helper, unused type imports, floating selectWorkspace promises voided,
member-delimiter newlines in inline type literals.
unbound-method flags destructuring a method-style member (method
signatures are bivariant and exempt from the this-context check).
These contract members are all plain callbacks — declare them as
property-style function types so consumers can destructure them
without a false this-binding hazard. Type-level only.
The group's convention is package suffix == provider default
(subagent-acp/'acp', subagent-spawn/'spawn', subagent-fork/'fork'), and the
provider default became dsh-sdk in the last review round — so the package
follows: @deepseek-ai/dsh-subagent-dsh-sdk at
packages/subagent/subagent-dsh-sdk, plugin name subagent-dsh-sdk,
diagnostics prefixed subagent-dsh-sdk:. The dsh echo has precedent
(dsh-llm-deepseek). Directory, fixture path, knip/tsconfig/examples
registrations, catalogs, READMEs (en+zh), and the Agent Note follow; the
sdk-client dispose ladder moves to its own module (src/dispose.ts) with the
deterministic FakeChild tier tests restored alongside it.
Master's #660 replaced dsh-subagent-subprocess with the dsh-subprocess
capability seam (ctx.subprocess + scrubbedParentEnv, tree-scoped teardown)
and moved subagent-acp onto it. Convergence for this branch's packages:
- The shared out-of-process provider vocabulary this branch had grown in
the deleted library (NO_START_CAPABILITIES, assertPositiveFinite, cwd
resolution, settleRunResult, subprocessRunHandle) moves into the subagent
seam package as out-of-process.ts — it enforces subagent-seam contracts,
not process mechanics, and both out-of-process backends now import it
from there (subagent-acp keeps master's shape otherwise).
- subagent-sdk spawns THROUGH the SDK client (the subprocess README's
documented exception for SDK-managed transports) and now applies the
seam's scrubbedParentEnv() + explicit-env merge in place of the deleted
buildChildEnv.
- sdk-client inlines the EOF→SIGTERM→SIGKILL ladder as private helpers (it
runs outside any harness context, so it cannot ride ctx.subprocess).
- The child harness fixture gains the now-required dsh-subprocess-local
entry for bash-local; the fixture cordis.yml keeps exercising the
shipped provider default.
Mechanical --fix output over the newly linted .tsx files (indent,
arrow-parens, comma-dangle, member-delimiter-style, unnecessary type
assertions), plus the three generic-arrow test hooks converted to
function declarations up front: the comma-dangle fixer strips the
<T,> disambiguation comma and turns them into parse errors otherwise.
.tsx sources and specs were invisible to every lint surface: the eslint
flat-config globs, the lefthook staged-file glob, and the jscpd clone
scan all matched *.ts only. Widen the five eslint file groups (source,
test, client-test, sonar, formatting), the pre-commit glob, and the
jscpd format/pattern to cover .tsx.
Existing .tsx files predate these lanes; follow-up commits on this PR
clear the backlog they surface.
