Why: make material, background work, confirmations and files accessible to nontechnical users across desktop and mobile.
Evidence: Dev SELF receipts for Frontend tsc, 190 tests, knip baseline, build, nine fixture browser cases and two real HTTP/browser smoke cases using MockRunner.
Impact: existing API and permissions remain authoritative; stale events/queries and duplicate effects are guarded, while one file preview and reading state are preserved.
Refs: work-companion-ui design r0.2 and plan r1 U2-U5; UI01-UI13.
Why: Streaming tool arguments looked like a frozen cursor, and a failed run folded the only narration into the collapsed process block.
Evidence: npx vitest run in modules/frontend, 13 files, 66 passed. npx tsc -b reports only a pre-existing missing docx-preview module.
Impact: Live tools move composing to running to done with arguments and output; finished runs lift the last narration; same-run errors and duplicate files collapse into the reply.

Why: Process output folded on every text delta, successful tool
results disappeared after refresh, and generated files stayed plain
text instead of a card that opens a closable preview.
Evidence: npx tsc -b --noEmit (clean); npx vitest run (51 passed).
Impact: Live work stays expanded until the run ends, then folds to
one worked-time line. File cards open a per-conversation preview pane.
docx renders page by page, with mammoth if that fails.

Why: tool artifacts were only reachable via the collapsed process
section or the artifacts workspace; users had to read model text to
learn a file existed. Deliverables should appear directly in the
conversation as an openable card (ZCode/Kimi pattern) that opens the
right-rail preview.
Evidence:
- Conversation.tsx artifact_ref renderer upgraded from a small chip to
a deliverable card (icon + name + kind/size meta + preview affordance
+ single download action); whole card click = rail preview (the one
preview placement, fullscreen still reachable from the rail header)
- live.ts projects artifact items as content parts pinned after the
reply text, isomorphic with the new llm.go persisted order; card is
visible while streaming
- styles: deliverable-card uses tokens only (radius-lg card, bg-raised,
hairline border, mk-rise-in entrance); design-guard suite green
- vitest 40/40 (live.test pinned-tail case updated, messageparts.test
covers new persisted order plus legacy inline order); tsc clean
Impact: every generated artifact (docx/pdf/image/…) now surfaces as an
in-chat card immediately, click-to-preview in the right rail with real
formatting for styled docx; workspace panel (⌘1) unchanged as the
file-system fallback.
Refs: task feature/deliverable-docx-r1 (backend: write_docx + pinned
artifact_ref)
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.
