Fixed sidebar width (never concedes), figma session-row rail (16px twist +
status slots, triangle arrows, mount fade), exact brand wordmark svg with
tooltip'd rail controls, form controls inheriting the app font stack, and
inlined the twist button reset since the tsdown CSS pipeline drops composes.
Two polish defects from the headless verification pass:
- .newSessionLabel/.footLabel declared their own transition shorthand,
which replaced .wide's opacity fade entirely (shorthands do not merge) —
the labels vanished instantly while everything else faded. The fade is
restated alongside max-width.
- The rail icons drifted off a common vertical axis: the 56px track holds
a 55px content box (1px column border), and the capsule rows kept their
1px border-width in the collapsed state, shaving their content to 23px
and pushing the search icon 2px right. Collapsed capsules now zero the
border-width (transitioning border, not border-color), the root gives
back the border pixel via asymmetric padding, and every surviving row
centers its icon — five glyphs on the track's 28px center.
The collapse read as a hard cut: only the track width animated while the
panel content swapped instantly and the rail icons bore no relation to the
expanded layout. Now the four control rows persist across the transition —
collapse toggle, new session, new workspace, search, the same top-down
order as their expanded rows — and morph their geometry (row heights,
paddings, margins, capsule borders) on the deepsuite curve, so each rail
icon is its expanded control converging onto the 56px axis. Wide-only
content (brand, labels, input, session tree) cross-fades over 200ms, stays
mounted while the collapse animates, and unmounts at the 300ms settle,
still dropping the sessions subscription. The search query moves up to the
root and survives the round trip; rail search focuses the surviving input
after expand instead of remount-autofocus.
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.
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.
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.
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.
ci: fix test/docs
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.
