All view components are now tsx JSX function components instead of
hand-rolled h() factories; the bundle externalizes the framework seed words
(react, @deepseek-ai/dsh-client-ui-primitives) so the loader module table
resolves the single shared framework instance at runtime.
Reuses shared ui-primitives where a clean fit exists (injection and
model-switch event glyphs -> IconPlusOutline16/IconBranchOutline16); the
bespoke data-viz chrome (charts, shared-hover tooltip) intentionally stays
custom but continues to draw the shared --dsw-alias-* tokens.
esbuild uses the classic JSX transform, so the emitted createElement trees
are isomorphic to the previous h() calls and the element-parsing tests, the
chart-render assertions, and the real-React repro all stay green unchanged.
Adds @deepseek-ai/dsh-client-ui-primitives as a type devDep and documents the
framework-reuse findings in docs/redesign.md §8.
Replace the custom /dsh-context RPC channel + 2s client polling with a native
contextTimeline session-projection unit: the host registers one pure
init/apply/view unit on ctx.sessionProjections (framework-driven, persisted by
the projection cache, streamed via session/projection push frames), and the
client reads the finished value through the framework standard
useProjection seat. Deletes the client stale-while-revalidate cache and the
local service type stubs; grows the modern shelf registration (locale) and
adds the published @deepseek-ai/* types as devDeps plus zod as the single
runtime dependency (wire schema, kept external in the host bundle).
Fixes tool-result node attribution to read the durable source.callId /
content toolCallId instead of the never-present block.callId (tool labels had
silently never rendered).
Retention is tightened to trim by whole turn-runs deterministically (bounded
state, no 1200<->1500 oscillation under incremental folding).
Tests now drive the projection unit directly (host) and feed the view through
a useProjection stub (client); all chart/render assertions preserved. Adds
docs/redesign.md (review + target architecture, phases 0-3 landed) and
docs/CLIENT_SURFACE.md (client-side audit).
- shared/types.ts: single wire contract (type-only) used by both halves
- host/: services (contracts), pricing (token-meter), fold (incremental fold
+ retention), snapshot (build + event turn/step attribution), index (RPC)
- client/: i18n, styles, format, categories, viewkit (shared deps),
cache (per-session stale-while-revalidate), components/* (one module per
component), view (composition root), index (plugin entry)
- first-screen: initial render seeds from the session cache, polling pauses
while the tab is hidden (resume + immediate fetch on visible), and a
transient fetch error never blanks already-visible data
- build.mjs: bundle:true for both halves (react external in the client
bundle); the client half is now covered by tsc --noEmit for the first time
- src/host.ts: typed fold model (Snapshot/RequestRecord/SurfaceNode/
ContextEventRecord), local drift-free service contracts for
connection/sessions/sessionQuery via declare module augmentation
- src/client.cts: typed client bundle (React types via @types/react,
locale/slots/connection contracts, typed component props); CJS-flavored
so esbuild keeps require/module.exports despite type:module
- tsconfig.json: strict, noEmit, verbatimModuleSyntax (runtime-free of
imports in the client bundle is enforced by the type system)
- scripts/build.mjs: esbuild transpile for both halves, loader wrap and
smoke checks unchanged; npm run typecheck added to the test suite
- note: @deepseek-ai/* service type packages publish broken dependency
chains on npm (dsh-paths 404), so local contracts replace them
