Overview

Follow-up to #333 (merged). Implements Allan Enemark's deferred Deep Research UI redesign plus the polish items that were split out of #333 to keep that PR tight.

Changes

  • Deep Research nav rail (DeepResearchRail): a persistent right-hand rail (Data Sources / Citations / Research / Thinking) that drives a single content panel, replacing the scattered app-bar Data Sources button and tab switching. Data Sources moves out of the app bar into the rail.
  • Panel resize: a keyboard-accessible drag grip between the chat and the panel, clamped to a sensible min/max; the width transition is disabled while dragging and reduced-motion is respected.
  • Consolidated Citations (ResearchSourcesView): a single sources view with an All / Cited filter. ThinkingTab is reduced to a pure step trace (its Sources sub-tab removed, since Citations now owns sources).
  • Polish: dividers between chat turns, a smoother Sessions-panel collapse animation, and consistent borders/toggles.
  • Review follow-up (Allan): a live activity indicator on the rail plus an animated "Deep research in progress" state in the report panel; removed the placeholder Artifacts panel; better spacing on the panel close/stop controls; a chat-area min-width; and a pointer cursor on the rail buttons.

Follows the #333 review principles

  • Citations come from the authoritative final-report metadata. The Citations view derives cited sources from splitReferences(reportContent) (the same source ReportTab uses), so citation numbers match the report's inline [N] rather than discovery order. Uncited stream reads are shown under "Other sources found", with a stream fallback only when the report has no reference block.
  • No hard-coded data sources (the rail lists panel names, not sources).
  • Correlation stays id-keyed; no new name-based matching added.
  • No Markdown-intent guessing added.
  • New panel/width state is UI-only; no cross-session state introduced.

  • tests/aiq_agent/test_default_model_profiles.py::test_deprecated_model_and_endpoint_references_are_absent passes (no deprecated model/endpoint strings in the diff).

  • New/updated tests: ResearchSourcesView authoritative-order test (cited numbers follow the report [N], not discovery order); DeepResearchRail, panel-resize, store auto-collapse, and ThinkingTab-no-Sources-subtab specs.

  • I ran the relevant local checks or explained why they are not applicable.

  • I added or updated tests for behavior changes.

  • Docs: no changes needed; this is UI-internal panel behavior not covered by the Sphinx docs.

  • I confirmed this PR does not include secrets, credentials, or internal-only data.

  • I certify this contribution under the Developer Certificate of Origin (DCO) and signed my commits with git commit -s.

  • I replaced the DCO sign-off placeholder with my GitHub commit identity and kept the required angle brackets around the email address.

Where should reviewers start?

  • frontends/ui/src/features/layout/components/ResearchSourcesView.tsx — authoritative citation derivation (the highest-risk area from the feat(ui): re-skin the chat experience (stacked on #331, #332) #333 review).
  • frontends/ui/src/features/layout/components/DeepResearchRail.tsx and ResearchPanel.tsx — the rail model and the drag-to-resize.

Walkthrough

The layout adds a persistent Deep Research rail for five right-panel views. ResearchPanel renders report, thinking, citation, and artifact content with resizing and panel-specific loading. Sources support cited and uncited grouping. Chat and sidebar presentation also change.

Changes

Deep Research layout

Layer / File(s) Summary
Rail navigation and panel state
frontends/ui/src/features/layout/types.ts, frontends/ui/src/features/layout/store.ts, frontends/ui/src/features/layout/components/DeepResearchRail.tsx, frontends/ui/src/features/layout/components/MainLayout.tsx, frontends/ui/src/features/layout/components/AppBar.tsx, frontends/ui/src/features/layout/index.ts
The layout adds five rail panels, shared panel toggling, sidebar auto-collapse behavior, and a persistent far-right rail. The AppBar no longer renders Data Sources controls.
Shared research panel content
frontends/ui/src/features/layout/components/ResearchPanel.tsx, frontends/ui/src/features/layout/components/ThinkingTab.tsx, frontends/ui/src/features/layout/components/ResearchPanel.spec.tsx, frontends/ui/src/features/layout/components/ThinkingTab.spec.tsx
ResearchPanel renders report, thinking, citations, and artifacts views with panel-specific loading, resizing, active headers, and conditional stop controls. ThinkingTab shows agent steps and generated files without a Sources sub-tab.
Citation and source rendering
frontends/ui/src/features/layout/components/ResearchSourcesView.tsx, frontends/ui/src/features/layout/components/ResearchSourcesView.spec.tsx
The sources view groups cited and uncited sources, supports All and Cited filters, and handles empty states and citation ordering.
Layout and conversation presentation
frontends/ui/src/features/layout/components/ChatArea.tsx, frontends/ui/src/features/layout/components/SessionsPanel.tsx, frontends/ui/src/features/layout/components/SessionsPanel.spec.tsx, frontends/ui/src/features/layout/components/DataSourcesPanel.tsx, frontends/ui/src/features/layout/components/DataSourcesPanel.spec.tsx
Conversation turns gain separators. The sessions sidebar keeps labels in the DOM while collapsed. Header and search spacing are updated, and the Data Sources header uses a fixed shared height.

Estimated code review effort: 4 (Complex) | ~60 minutes

Merge Risk: 🔵 Low · up to 774fa

The change is mergeable with owner awareness: the initial wide panel state can exceed its intended limit and report an inaccurate accessible width, while differently formatted equivalent citation URLs can cause duplicate sources to appear. These are localized follow-ups rather than release-blocking risks.

Inline comments:
In `@frontends/ui/src/features/layout/components/DeepResearchRail.tsx`:
- Around line 118-151: Add visual validation evidence for the updated
DeepResearchRail component: capture a screenshot showing the Deep Research rail
with an opened panel, and include it with the change as required for visible UI
updates.

In `@frontends/ui/src/features/layout/components/ResearchPanel.spec.tsx`:
- Around line 310-321: Add a concise comment or update the assertions in the
arrow-key resize tests around the ResearchPanel width expectations to explicitly
reference the 640px FALLBACK_WIDE_WIDTH fallback and the viewport-dependent
clamp assumption, preferably using the exported constant where available;
preserve the existing resize behavior assertions.

In `@frontends/ui/src/features/layout/components/ResearchPanel.tsx`:
- Around line 307-312: Update the resize event bindings to invoke
handleResizePointerUp for both pointerup and pointercancel, ensuring cancelled
gestures clear resizeStartRef and reset isResizing just like normal completion.
- Around line 353-364: Update the focusable separator in the ResearchPanel
resize control to include aria-valuenow, aria-valuemin, and aria-valuemax, using
the current panel width and the same clamp bounds used by the resize handlers
and handleResizeKeyDown. Keep the keyboard resizing behavior unchanged while
exposing the width range to assistive technologies.
- Around line 205-223: The panel-load guard caches loadKeyRef.current before the
asynchronous load succeeds, preventing retries after failure. Update the
useEffect flow around loadResearchPanelTab and importStreamOnly to clear the
cached key when either load rejects, or assign it only after successful
completion, while preserving the existing duplicate-load prevention.

In `@frontends/ui/src/features/layout/components/ResearchSourcesView.tsx`:
- Around line 43-53: Update the report-source offset in splitReferences so it
uses the maximum source.index from reportSources, then pass lastReportIndex +
index to mapCitationSource instead of reportSources.length + index. In
frontends/ui/src/features/layout/components/ResearchSourcesView.spec.tsx lines
142-153, assert the rendered index for read.example and add a report fixture
with non-contiguous references such as [1] and [5].

Apply the same fix in
`@frontends/ui/src/features/layout/components/ResearchSourcesView.spec.tsx` around
lines 142 - 153.

In `@frontends/ui/src/features/layout/components/ThinkingTab.tsx`:
- Around line 41-66: Extract the duplicated generated-files disclosure from
ThinkingTab and the corresponding ReportTab, ResearchPanel ArtifactsView, and
ThinkingView implementations into a shared GeneratedFilesSection component,
preserving the existing deepResearchFiles input, toggle behavior, FileCard
rendering, and styling. Reuse the shared component everywhere and ensure its
trigger includes the expected cursor-pointer styling consistently.

41-66: The generated-files disclosure is still duplicated across ThinkingTab, ReportTab, and the ThinkingView/ArtifactsView blocks in ResearchPanel.tsx. The cursor-pointer divergence is fixed here, but the shell itself is unchanged. This was raised in a previous review.

@Manushpm8 Looking really good! The panel transitions are slick. Also the thinking panel format is well done.

Reference:
Screenshot 2026-08-24 at 10 43 54 AM

Minor suggestions:

  • Need more indication that "deep research is happening" - right now only see some activity in the left panel. Maybe each item in the deep research panel gets some activity icons while its on-going? Its a bit jarring to see the report panel open w/o any activity in it. Maybe oppertunity for a fun little animation inside it ala claude.
  • The "artifacts" panel can probably be removed; it was ment as a location for plugins or agents (i.e. make powerpoint slides).
  • Relocate or better space the X to close panel next to the stop research button - never really liked this location TBD, maybe keep stop deep research consistent with the stop shallow research button in the prompt area.
  • Set a min width for the chat area - on super small windows, not usable, good to have as backup functionality.
  • Deep Research panel buttons should have pointer cursor on hover / hover over effect.

OMG talk to report is working <3

@exactlyallan thanks for the review! All 5 suggestions are in: a live activity indicator on the rail plus an in-progress state in the report panel, removed the Artifacts panel, better spacing on the close/stop controls, a chat-area min width, and pointer cursors on the rail buttons. All tested and green, and the screenshots are refreshed. Ready for another look.

The failing Script Validation check is unrelated to this PR and pre-existing on develop. It is a repo-wide uv audit failure on a chromadb CVE (GHSA-f4j7-r4q5-qw2c, no patched version yet) that is also red on develop and every open PR. This change is frontend-only and otherwise green (Pytest, UI checks, lint, and DCO all pass).

frontends/ui/README.md still documents separate Tasks/Thinking/Report tabs and a standalone Tasks tab, although this PR removes that model and folds Task progress into Thinking.

Can you check CI as well? CI is passing on develop branch

…nes/toggles (follow-up)

- Chat transcript: add a hairline divider (border-t border-base) with pt-8 above every turn after the first, so each user message plus its steps trace and answer reads as one group, clearly separated from the next.
- Sessions sidebar collapse: anchor the leading nav icons at a fixed horizontal position across states (uniform px-2.5) and fade the labels out via opacity instead of unmounting them, so the icons no longer jump and the text no longer vanishes instantly.
- Normalize the ResearchPanel toggle hover border from the hardcoded #76B900 hex to the shared border-brand token utility.

Add a persistent far-right Deep Research rail (Data Sources, Citations, Research, Artifacts, and Thinking pinned at the bottom) whose items toggle a single content panel opened to its left. Reuse the existing Data Sources, Report, Thinking, sources, and file components for the panel content; fold the former Tasks tab into the Thinking view as a collapsible Task progress disclosure. Remove the top-bar Data Sources button and the Show Research vertical tab; keep the theme toggle and avatar.

…ations

Two scoped fixes to the Deep Research rail redesign.

Drag-to-resize: add a focusable role="separator" grip on the panel's
left (chat-facing) edge. Pointer drag and ArrowLeft/ArrowRight nudge the
width live, clamped between the per-class minimum (480px wide, 420px
narrow) and min(900px, 70vw) so it never covers the viewport or shrinks
below the minimum. The width transition is disabled while dragging so the
edge tracks the pointer, and reduced-motion is still respected. The
chosen width is held on the always-mounted panel so it survives panel
switches, and it is re-clamped to the active minimum when the panel class
changes so a narrow width can never persist illegally on a wide panel.

Sources consolidation: the Citations panel is now the single home for
every source the agent touched. It renders the merged, stream-backed
citation list (ResearchSourcesView) with the All/Cited filter and the
"Cited in report" / "Other sources found" groups, using the compact
single-line SourceList rows rather than large cards. Thinking drops its
Steps/Sources sub-tab bar and is now purely the reasoning/steps trace
with the generated-files disclosure intact. Both surfaces read the same
deepResearchCitations array, so the counts match and no uncited reads are
lost.

Addressed all review comments in 7d6c9fc (rebased on latest develop): the MainLayout content row now scrolls so the rail and Data Sources close control stay reachable at 1024px (with a viewport test); View Progress opens the Thinking panel for active jobs; panel width re-clamps on window resize; the retry spec now drives the real reset-on-close path; and frontends/ui/README.md is updated to the rail model (Data Sources / Citations / Research / Thinking, Task progress folded into Thinking, no standalone Tasks tab, no Artifacts panel). Green: type-check, lint, and test:ci (1790 passed).
