Why: the merge commit left tsc broken in two spots - an artifact.created
handler still pushing to the removed LiveState.parts, and main's newer ui
icons not yet checked out in this worktree; also Part was imported unused.
Evidence: artifact.created now appends an artifact LiveItem (process=true,
matching the backend's ae8e5d0) projected to artifact_ref by
liveToMessage; new test asserts it lands after its tool call. tsc -b exit
0 after initializing the ui submodule checkout; vitest 33/33.
Impact: live artifact chips render inside the process stream and fold on
reconcile; no functional change elsewhere.
Refs: feature/chat-process-split-r1
Why: main advanced with PR #15/#16 (part-order preservation, artifact
downloads, cross-session UI); task-sync requires the branch to carry it.
Evidence: resolution keeps the arrival-ordered items stream from this
branch (tool-driven process marking, pure/testable logic in live.ts) and
adopts main's rendering and ids: groupParts in-place process blocks,
real tool callIds on live tool parts, messageparts utilities, and the
restored phase-driven showProcessInline predicate alongside the CF0
long-reply excerpt that main's rewrite had dropped. vitest 32/32
(includes main's messageparts suite and this branch's 12 live cases);
tsc -b clean.
Impact: single coherent live pipeline - items accumulate in event order,
liveToMessage projects Parts with tool-driven process marks, rendering
folds consecutive process blocks in place; responding still collapses
the process area (Cursor-style) as originally reviewed.
Refs: feature/chat-process-split-r1
Why: liveToMessage emitted all text buckets then all tools, while the
persisted message interleaves per turn (thinking, text, calls), so parts
reordered on reconcile with 2+ tool turns. Commentary stayed in the reply
area until the next turn's text bucket appeared, because the process flag
was positional (i < length - 1) instead of tool-driven.
Evidence: LiveState now holds an arrival-ordered items stream
(thinking/text deltas merge into their last segment; tools land in place),
so event order - which matches the backend's per-turn append order - maps
1:1 onto persisted parts. A text segment is process iff a tool.call lands
before the next thinking/text segment, aligning with the backend's
Process: len(calls) > 0; the collapse predicate moved to testable
showProcessInline. Long replies (>800 chars) now show a 100-char excerpt
and label the count as Markdown source length. vitest 27/27 pass (was 5
live cases, now 12 incl. multi-turn order, immediate process marking,
collapse predicate); tsc -b clean.
Impact: streaming UI no longer reshuffles parts across turns or on final
reconcile; tool-turn commentary folds into the process area as soon as the
tool call arrives. Residual edge (documented in live.ts): a silent
tool-only turn with no text and no thinking attributes its call to the
previous text segment.
Refs: code review of feature/chat-process-split-r1 (2026-09-30)
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.
Refs: task feature/chat-order-artifact-files (ui# c3e1f3b backend#
44b51fa).
Why: creation entries were split (project + at sidebar top-left, new
session at bottom-left) and the project tree forced per-project
navigation; the approved option A design makes one primary New Task
entry, organization a view mode, and identity always present.
Evidence:
- New TaskSidebar: single New Task split button (current-project context,
Cmd-N, secondary menu for new project / new task in project), project
<-> timeline organization with persisted collapse, pinned section,
archive view toggle, hover row actions, account footer fed by
/api/me (embedded mode shows local tenant; logout clears the key),
workspace icon strip retained (D25 shared list with Cmd-1..9).
- store: tasks = cross-project list via GET /api/conversations; openTask
switches project context; pin/archive optimistic + refresh; last
project context persisted; stale conversations field removed.
- tasklist.ts pure helpers + 6 vitest cases; npm run build passes;
headless walk on the real binary: cross-project open, pinned-first,
archive hide/show/restore, new-task flow, zero console errors.
Impact: ProjectNav removed; contracts.ts regenerated from core
(pinned/archived); no composer/right-pane changes (D25/D26/D31 intact).

Details (original message):
Implement the three-column workbench frontend: resizable/collapsible nav with overshorthand collapse, streaming chat with part renderers and process collapse, HITL choice cards with impact display and free-input pivot, plan/todos/artifacts/agents tabs, subagent tracker modal, schema-driven settings center with effect badges and masked secrets, profile management with import/export, plugin panel rendering, doc viewer with edit-save; contract shape tests.
