Why: Approved redesign phase 3: one artifact = one preview placement
(right rail by default; full-screen overlay as the only large-window form)
plus a single download button per surface. Removes the redundant
three-action chips/rows and the nested modal chrome in AgentTracker.
Evidence: npx tsc -b clean; npm test -> 38 passed. Combined runs recorded
in the Dev task card.
Impact: new store.requestPreview() is the single preview entry (Command
semantics; placement derived there); artifact chips and workspace rows
reduce to title-click = rail preview, eye = full preview, download;
docBridge card opens route through the same entry; AgentTracker drops its
inner .modal shell (OverlayHost is the only chrome). No API changes.
Refs: Agent-System-Dev task feature/ui-tokens-v3 (phase 3).
Why: Approved redesign phase 2 (IA): normal users run projects entirely
through conversation; system capabilities (user management, agent profiles,
plugin management, plugin-declared workspaces) belong behind a dedicated
admin entry, not in the user-facing sidebar or settings. The sidebar
workspace strip is removed; artifacts stay reachable via the right-rail
tab and conversation chips.
Evidence: npx tsc -b clean; npm test -> 38 passed (design-guard ratchet
still green). Full combined run recorded in the Dev task card.
Impact: new AdminZone full-screen view with a declarative section registry
(users/profiles/plugins/plugin-workspaces via UIRenderer); sections moved
out of SettingsModal (now personal preferences only) and AdminUsersModal
(now password change only); store ui.adminUsersOpen renamed adminZoneOpen;
workspaceEntries narrowed by role so plugin entries no longer take Cmd1-9
for regular users; theme toggle moved into the account menu.
Refs: Agent-System-Dev task feature/ui-tokens-v3 (phase 2).
Why: the adjudicated plan (D1-D4) calls for office/link previews with
loaders injected from the host, right-rail light preview alongside the
overlay viewer, and artifact deletion kept as an API capability with no
UI entry.
Evidence: previewsetup.ts injects docx (mammoth), xlsx (SheetJS, sheet
tabs, 200-row cap), pptx (pptx-preview full-fidelity; pptx2html was
dropped for a broken module entry — tXml case mismatch breaks Linux
builds — per the D2 fallback clause), and the /api/url-preview fetcher,
all via dynamic import: the main entry grows ~12KB while xlsx (430KB),
pptx (1.2MB) and jszip (98KB) load on first preview. DocViewer becomes a
FilePreview container (keeps text-family editing); Workbench gains a
preview tab with rail-preview state (store.railPreview); artifact chips
and panel rows gain a rail-preview action; the panel delete button is
removed while api.deleteArtifact and DELETE /api/artifacts/{id} remain.
tsc clean; vitest 33 passed; production build succeeds.
Impact: previews work end to end for the whole format matrix; deletion
stays plugin-reachable only.

Why: AssistantMessage reordered a message's parts by the process flag,
so tool calls floated above the text that surrounded them instead of
appearing where they actually ran; live streams had the same defect via
a fixed template order and never showed artifacts mid-run. Generated
files (e.g. meeting-minutes docx) had no visible download path, the
artifacts panel was a bare list, DocViewer nested a modal inside the
overlay, and settings rows used a legacy grid with a floating save
button.
Evidence: messageparts.ts adds groupParts (order-preserving grouping of
consecutive process parts, unit-tested) plus humanSize/artifactIcon
helpers; Conversation renders blocks in original order and the artifact
chip becomes icon + open + download; LiveState.parts accumulates events
in arrival order including artifact_ref so live view matches the
persisted message; ArtifactsPanel gains search/kind filter/upload and
per-row preview/download/delete-confirm; DocViewer is a single-layer
OverlayHost with pdf iframe, csv/json monospace, and a binary info card
with a download CTA; SettingsModal migrates to @ui SettingRow with the
save button pinned in the shell actions bar; inbox cards receive the
docBridge so result cards can open artifacts. tsc clean, vitest 20
passed, production build succeeds.
Impact: message timelines read in true execution order during and after
runs; every artifact is previewable and downloadable from the message
chip, the workspace panel, and the viewer; settings render on the fixed
two-column shell.
