The collapsed rail becomes a 56px icon column (24px controls between 16px
paddings) carrying expand, new session, search, and new workspace — each
aligned with its expanded counterpart; rail search expands the sidebar and
focuses the search box. Collapse/expand now animates: the frame transitions
grid-template-columns (and the surviving handle its left) on the deepsuite
sider curve — --ds-ease-in-out over --ds-transition-duration-slow, supplied
by ui-theme's base sheet. Transitions pause during drags (data-dragging on
the frame, set for the whole gesture) and under prefers-reduced-motion.
Since the store engine moved into the client runtime, the ui-layout bundle
externalizes @deepseek-ai/dsh-client-runtime/client. This case's two-row
manifest (ui-layout + a deliberately absent probe) no longer boots ui-layout
at all: the unseeded runtime specifier fails it first, serial loading stops,
and the probe never reaches the failure list, so the assertion times out on
a premise the engine migration retired.
A closed sidebar previously resolved to a zero-width grid track, clipping
the only toggle and the settings entry with no visible recovery; the closed
preference persisted across reloads, locking the sidebar shut.
- columns.ts maps the closed preference (width 0) to a fixed 60px
SIDEBAR_COLLAPSED rail through every step of the concession solve;
closed details still resolve to zero width.
- AppFrame derives data-sidebar-collapsed and the sidebar slot's collapsed
owner prop from the persisted preference instead of the resolved track
width, and drops the resize handle while collapsed.
- SidebarRoot reads the owner collapsed prop; the expanded-only body is a
separate component that unmounts while collapsed (dropping its sessions
subscription), leaving the expand toggle and Settings in the rail.
- The keyless web smoke gains the ui-sidebar bundle (six real bundles) and
pins the 60px rail collapse/expand round through the assembled client.
The store migration (#538) parked the engine in a store/ sibling domain;
loader and sessions imported it directly, tripping verify-client-domain-graph
(cross-domain shared surface must route through contract/). The engine is
layer-0 shared infrastructure by definition, so it moves to contract/store.ts
verbatim; the four importers and the spec follow mechanically.
Three notes stated tsconfig.build.json as present-tense fact; the
aggregates (tsconfig.host.json / tsconfig.client.json) now own the
explicit reference lists and the root solution owns the emit graph.
Historical narration in dated notes is left untouched.
New authoritative section docs/development.md#typescript-project-layout
(five files, three roles, the program-vs-resolution principle and its two
disciplines), two repo conventions in AGENTS.md, package tsconfig shape in
packages/AGENTS.md, cookbook touch-lists updated for the two aggregates,
test source-plane rule in docs/testing.md. Decision record: new Agent Note
2026-07-22-tsconfig-solution-root-two-aggregates; ts-build-config note
updated in place (tsc-first pipeline unchanged); the two GUI RFCs now name
tsconfig.host.json. All bilingual pairs re-recorded. Doc budget ceilings
raised: AGENTS.md 1680, docs/testing.md 1020, packages/AGENTS.md 660 (two
new one-line conventions and one new section on already-near-ceiling docs).
Mission spec for the code-side migration: missions/tsconfig-single-graph-migration.md.
tsconfig.vitest.json is deleted; its job (a paths map applying to all
test files) is inherent in tsconfig.base.json having no include —
vite-tsconfig-paths treats that as match-all. All four vitest configs
now pin the same facade: the unit config gains a shared pathsPlugin()
helper, the web lane drops its handwritten webserver alias (apps/web
tests are covered by match-all), and the snapshot lane leaves the root
solution (which no longer carries paths) and stops resolving client
imports through package exports. tsconfig.base.json documents the
facade role and bans include/files; the CI eslint cache key hashes the
four graph tsconfigs; the eslint tests-block comment states resolution
via the solution to tsconfig.host.json.
Per missions/tsconfig-single-graph-migration.md §3.
Root tsconfig.json becomes a pure solution (files:[] + two references);
the former root host aggregate moves verbatim to tsconfig.host.json.
New tsconfig.base.client.json carries the shared client compiler shape
(jsx/DOM lib/types:[]), and tsconfig.client.json plus the 12
packages/client tsconfigs extend it instead of restating the trio.
tsconfig.build.json is deleted: the solution covers the full emit graph,
absorbing the command-goal typecheck/build drift.
Consumers migrate to the single graph: typecheck/build scripts and the
lefthook pre-push hook run bare `tsc -b` (pre-push now covers the client
side); the run-gates build gate needs typecheck so two concurrent tsc -b
runs cannot race the same tsbuildinfo; ts-project.ts and the standalone
doc-typecheck mode seed tsconfig.host.json explicitly (never the root
solution — flattening host+client into one program collides the cordis
Context merges); verify-cordis-config BFS seeds the root solution alone.
Per missions/tsconfig-single-graph-migration.md §2–§3.
The data layer no longer depends on the React glue package, and business
plugins no longer depend on web-react at all:
- The store engine (zustand vanilla + immer + persist + dev freeze),
defineStore, and shallowEqual move to @deepseek-ai/dsh-client-runtime,
exported from the ./client main entry — no ./store subpath survives on
either package (the web-react one is deleted, none is opened on runtime).
- Store products are bare snapshot sources: useSelector leaves
SnapshotStore/StoreInstance and Session; every hook is composed at the
binding site in web-react's renderer (per-source cached uSES binding).
The SlotRendererHost sessions face carries bare observables only.
- SessionProvider becomes a standard-kit seat: an entry whose children
declare a session-scope slot receives the framework component as a prop,
retiring the last value import of web-react from plugin packages.
UseSession and the session-area types now live in ui-slots.
- web-react shrinks to the shell-only React glue (renderer, providers,
uSES bridge); zustand/immer belong to runtime alone; the module-table
seed and tsdown externals drop the web-react/store seat.
- NODE_ENV replacement is defined once in the shared tsdown client preset
(browser bundles inline the engine and lost vite's define); the 3-line
process.env typecheck shim moves to runtime with the engine.
- Stray tsc artifacts (.js/.d.ts/.d.ts.map beside sources under src/)
swept repo-wide; they shadow real sources under vitest resolution.
Verified: both aggregate typecheck programs at zero; 604 client tests
green; repo-wide grep for web-react/store at zero; real-host playwright
run 7/7 including persist round-trip.

The definitive slot model for the web client, replacing the first-generation
define/register two-step, ScopedSlots whitelist faces, and binding handles:
- 'root' is the only a-priori slot (SlotsService built-in); the shell renders
exactly ctx.slots.renderSlot('root', {}).
- register is the single API: children = slot declaration + render
authorization + runtime spec in one options object; misconfiguration fails
loud at load (duplicate declaration, undeclared contribution, one store
handle under two scopes).
- Component props arrive in four auto-derived shares: PropsRuntime<K>
(owner params + session/global standard kits via declare-merge),
PropsRenderSlots<S>, PropsStore<H>, and the inject business face.
sessionId is framework-supplied; hooks are framework-made only.
- Framework store seat: defineStore factories declare schema/actions/persist;
read = useStore, write = baked actions only; store scope derives from the
mounting entry; per-session persist keys and clearPersisted lifecycle.
- inject factories read the apply closure's own ctx (binding handles retired;
root-ctx back door closed); SessionProvider is self-wired render-prop.
- Rendering sits behind the SlotRenderer install seam; runtime stays
React-free; ownership ledger keyed to the single entry axis closes the
stale-authority window (StaleAuthorizationError probes).
Docs: the slot type-chain note is refreshed in place as the slot system
standard RFC (bilingual pair re-recorded); the web client architecture RFC
defers its slot sections there; packages/client/AGENTS.md gains the slot and
props discipline; gui-testing/web-styling notes drop missions/ references.
Tests: suites rewritten to the standard (props fed directly, real store
engines via createXXXStore().create(), no render machinery); load-time
negative samples for declaration/authorization/store conflicts; verified by
real-host playwright run (three columns, empty state, collapse, keyed session
remount, cross-slot selection sharing).
docs(ui-sidebar): point contract reference at the committed slot standard RFC
missions/ is workspace-local and never committed; the README must not cite it.
