Key enhancements:
- Simplified app shell to Top Navigation + Tabs pattern
- Added validated shadcn/ui component recommendations per section
- Updated code snippets to use shadcn primitives (table, chart, collapsible)
- Added installation commands and theme configuration
- Cross-referenced all three parts with navigation links

69-90: ⚠️ Potential issue | 🟠 Major

Call settings.is_development() to avoid always-on dev config.

app/core/config.py (Line 158-160) defines is_development as a method, but here it’s used as an attribute. A bound method is always truthy, so docs and dev CORS origins will be enabled even in production (Line 69-90).
Please call the method or convert it to a @property.

In `@frontend/src/components/charts/backtest-folds-chart.tsx`:
- Line 68: The dynamic Tailwind class h-[${height}px] in the ChartContainer
usage won't be picked up by Tailwind JIT; update the ChartContainer invocation
in backtest-folds-chart.tsx to remove the dynamic h-[${height}px] from className
and instead set the height via an inline style (e.g., style={{ height:
`${height}px` }}), keeping the rest of the className (w-full) unchanged; mirror
the same fix used in time-series-chart.tsx so Tailwind classes remain static
while the height is applied at runtime.

In `@frontend/src/components/charts/time-series-chart.tsx`:
- Around line 76-95: The chart lines use hardcoded CSS vars instead of the
configured colors, so when custom data keys are passed the stroke becomes
invalid; update the Line components (the block controlled by showActual and
showPredicted in TimeSeriesChart / the component rendering these <Line>
elements) to read the color from chartConfig using the dynamic keys (actualKey
and predictedKey) and fall back to the existing CSS vars if not present—e.g.,
set stroke to chartConfig[actualKey]?.color || 'var(--color-actual)' for the
actual line and chartConfig[predictedKey]?.color || 'var(--color-predicted)' for
the predicted line. Ensure references use the exact symbols actualKey,
predictedKey, and chartConfig so the fix works with custom keys.
- Line 60: The dynamic Tailwind class h-[${height}px] in the ChartContainer JSX
won't be picked up by Tailwind's static parser; remove the dynamic bracketed
class and apply the height via an inline style on the ChartContainer (e.g., set
style={{ height: `${height}px` }}) while keeping the static className parts such
as "w-full"; update the ChartContainer usage in the time-series-chart component
to use the inline style and static className instead of h-[${height}px].

In `@frontend/src/components/data-table/data-table-pagination.tsx`:
- Around line 21-83: pageCount can be -1 for manual pagination which breaks the
display and makes the "last page" onClick call table.setPageIndex(pageCount - 1)
with a negative value; compute a safe display count (e.g. safePageCount =
pageCount > 0 ? pageCount : 1) for the "Page X of Y" text and change the
last-page Button to guard its onClick so it only calls
table.setPageIndex(pageCount - 1) when pageCount > 0 (and keep the disabled prop
true when pageCount <= 0 or !table.getCanNextPage()); update uses of pageCount
in the last-page Button (and any related logic) to use these guards so no
invalid negative index is set.

In `@frontend/src/components/ui/accordion.tsx`:
- Around line 28-47: The AccordionTrigger wrapper drops refs which breaks
focus/ref-based behavior and Radix compatibility; update the AccordionTrigger
function to use React.forwardRef so it accepts a ref parameter and forwards it
to AccordionPrimitive.Trigger (preserving existing props and className
handling), ensure the forwarded ref is typed compatibly with
AccordionPrimitive.Trigger (use React.ComponentPropsWithRef or forwardRef
generic for AccordionPrimitive.Trigger) and return the same JSX but pass the ref
through to the Trigger element to restore focus management and asChild support.

In `@frontend/src/components/ui/button.tsx`:
- Around line 41-61: The Button component currently omits an explicit button
type which causes HTML buttons to default to "submit" inside forms; update the
Button function so the rendered element (Comp) always receives a default type of
"button" when none is provided by the caller (use props.type ?? "button").
Locate the Button function and the Comp element, destructure or read props.type,
and ensure you pass type={props.type ?? "button"} (or extract { type, ...rest }
= props and then spread rest and set type={type ?? "button"}) so callers can
override but the default prevents accidental form submission.

In `@frontend/src/components/ui/skeleton.tsx`:
- Around line 1-13: The file is missing the React namespace import required for
using React.ComponentProps; add an import for React (e.g., import * as React
from "react") at the top of the file so the Skeleton component signature
(function Skeleton({ className, ...props }: React.ComponentProps<"div">))
compiles; keep the existing cn usage and export { Skeleton } unchanged.

In `@frontend/src/lib/api.ts`:
- Around line 55-63: response.json() can throw for empty or non-JSON error
bodies which converts HTTP errors into parse exceptions; update the logic around
the call in the function using response.json() (inspect the variable data and
the ApiError construction) to try parsing JSON in a try/catch, and on failure
fall back to await response.text() (or an empty object) and map that into a
ProblemDetail-like shape before throwing new ApiError(detail.detail ||
response.statusText, response.status, detail); ensure you still only throw when
!response.ok and preserve ApiError, ProblemDetail and response.status usage.

In `@frontend/src/pages/chat.tsx`:
- Around line 37-95: The handleMessage callback can lose recent text deltas due
to stale streamingContent in its closure; use a ref (e.g., streamingContentRef)
as a synchronous buffer: on 'text_delta' update both setStreamingContent(...)
and streamingContentRef.current += event.data.content, and in the 'complete' and
'error' cases read from streamingContentRef.current (falling back to
event.data.content) when finalizing the message, then clear both
setStreamingContent('') and streamingContentRef.current = '' and reset
isStreaming/currentToolCall as before; update handleMessage to reference the ref
instead of relying on streamingContent in its dependency array.

In `@frontend/src/providers/theme-provider.tsx`:
- Around line 1-18: The interface uses React.ReactNode without importing React,
causing TS strict-mode errors; update the file to import the type and use it
directly: add "import type { ReactNode } from 'react'" at the top and change
ThemeProviderProps to use ReactNode for the children type (symbols:
ThemeProviderProps, ThemeProvider, NextThemesProvider, children).

`7-23`: _⚠️ Potential issue_ | _🟡 Minor_

**Duplicate chart color variable definitions with different color formats.**

The `--chart-1` through `--chart-5` variables are defined twice: once in `@layer base` (lines 8-22) using HSL percentages, and again in `:root` (lines 86-90) using oklch(). The `:root` definitions will override the `@layer base` ones due to CSS specificity, making the `@layer base` chart variables unused.

<details>
<summary>🔧 Suggested fix: Remove duplicate definitions</summary>

Remove the chart variable definitions from `@layer base` since they're overridden by `:root`:

```diff
 `@layer` base {
   :root {
-    --chart-1: 221.2 83.2% 53.3%;
-    --chart-2: 142.1 76.2% 36.3%;
-    --chart-3: 47.9 95.8% 53.1%;
-    --chart-4: 24.6 95% 53.1%;
-    --chart-5: 280.1 93.6% 53.1%;
   }
 
   .dark {
-    --chart-1: 217.2 91.2% 59.8%;
-    --chart-2: 142.1 70.6% 45.3%;
-    --chart-3: 47.9 95.8% 53.1%;
-    --chart-4: 24.6 95% 53.1%;
-    --chart-5: 280.1 93.6% 53.1%;
   }
 }

Alternatively, if the HSL values are intentional for some reason, consolidate them into a single location.

frontend/src/components/ui/popover.tsx-58-65 (1)

58-65: ⚠️ Potential issue | 🟡 Minor

Use <h2> for PopoverTitle to match props/semantics.

The component is typed with React.ComponentProps<"h2"> but renders a <div>, which loses heading semantics and allows invalid props.

In React, should a component typed as React.ComponentProps<"h2"> render an <h2> element to preserve semantics and prop compatibility?
🛠️ Proposed fix
 function PopoverTitle({ className, ...props }: React.ComponentProps<"h2">) {
   return (
-    <div
+    <h2
       data-slot="popover-title"
       className={cn("font-medium", className)}

102-116: ⚠️ Potential issue | 🟡 Minor

Remove aria-hidden from the parent and move it to the icon only.

The parent <span aria-hidden> removes the entire element and all descendants—including the SR-only text—from the accessibility tree. Screen readers won't announce "More pages". Move aria-hidden="true" to only the MoreHorizontalIcon since it's the decorative element.

Proposed fix
     <span

101-125: ⚠️ Potential issue | 🟡 Minor

Replace invalid Tailwind selector with correct arbitrary-variant syntax.

The selector *:[span]:last:flex is not valid Tailwind CSS v4 syntax. It appears to mix the children variant (*:), selector notation (used with has-[...]), and an invalid chained variant. To target the last span descendant, use the arbitrary-variant syntax [&_span:last-child] where the underscore represents a descendant space.

**Align active-filter state with the search threshold.**

When `search.length < 2`, the API doesn’t filter but `hasActiveFilters` still flips on. This can confuse users and makes “Reset” look active even though the query is unchanged. Consider normalizing search (trim + min length) for both the API param and active-state check.

Handle cancel errors + prevent duplicate submits.

handleCancelJob is async and invoked from onClick without error handling. If mutateAsync rejects, it can surface as an unhandled rejection and the action remains clickable. Prefer using mutate (with hook-level onError) or catch the error locally, and disable the action while pending.

💡 Suggested fix
-  const handleCancelJob = async (jobId: string) => {

109-173: ⚠️ Potential issue | 🟡 Minor

Reset all transient state when starting a new session.

createSession only clears messages but leaves streamingContent, isStreaming, currentToolCall, pendingAction, and isApproving uncleared. Similarly, handleNewSession misses isStreaming, currentToolCall, and isApproving. This causes stale state from the previous session to persist: the input remains disabled due to lingering isStreaming or isApproving, and tool-call indicators display for tools not running in the new session.

Suggested fix
   const createSession = async () => {
     setIsCreatingSession(true)
     try {
       const session = await api<AgentSession>('/agents/sessions', {
         method: 'POST',

🧹 Nitpick comments (33)
frontend/src/components/ui/tooltip.tsx (1)

55-55: Arrow styling has redundant and potentially conflicting styles.

Two issues with the Arrow styling:

  1. bg-foreground has no effect on SVG elements — only fill-foreground is needed.
  2. The custom rotate-45 and translate-y transforms may conflict with Radix's built-in arrow positioning logic.

Consider simplifying to let Radix handle arrow rendering:

♻️ Suggested simplification
-        <TooltipPrimitive.Arrow className="bg-foreground fill-foreground z-50 size-2.5 translate-y-[calc(-50%_-_2px)] rotate-45 rounded-[2px]" />
+        <TooltipPrimitive.Arrow className="fill-foreground" />

If the custom arrow shape is intentional, verify it renders correctly across all side positions (top, bottom, left, right).

frontend/src/components/ui/navigation-menu.tsx (1)

8-156: Add React.forwardRef to wrapper components to preserve ref passthrough.

Without ref forwarding, consumers can’t attach refs to the Radix primitives, which can limit focus management or integrations and diverges from common Radix/shadcn patterns. Apply the pattern to NavigationMenu, NavigationMenuList, NavigationMenuItem, NavigationMenuTrigger, NavigationMenuContent, NavigationMenuViewport, NavigationMenuLink, and NavigationMenuIndicator.

Proposed pattern (example for NavigationMenuTrigger)
-function NavigationMenuTrigger({

89-98: Consider adding a maximum delay cap for exponential backoff.

The exponential backoff formula baseInterval * Math.pow(2, reconnectCount) can grow very large. With 5 attempts and 3000ms base interval, the 5th attempt would wait 48 seconds. Consider capping the maximum delay.

frontend/src/components/ui/tabs.tsx (1)

7-23: Consider forwarding refs in all four Tab wrapper components to enable consumer access to underlying Radix primitives.

These wrappers are plain functions, so any ref passed to Tabs, TabsList, TabsTrigger, or TabsContent won't reach the underlying primitive. This blocks consumers from accessing refs when needed for focus management, measurements, or other direct DOM operations. React.forwardRef with proper typing preserves ref support in accordance with Radix UI best practices.

Apply the forwarding pattern consistently:

♻️ Ref-forwarding pattern (apply to all four components)
-function Tabs({
-  className,
-  orientation = "horizontal",
-  ...props
-}: React.ComponentProps<typeof TabsPrimitive.Root>) {
-  return (
-    <TabsPrimitive.Root
-      data-slot="tabs"
-      data-orientation={orientation}
-      orientation={orientation}
-      className={cn(
-        "group/tabs flex gap-2 data-[orientation=horizontal]:flex-col",
-        className
-      )}
-      {...props}
-    />
-  )
-}
+const Tabs = React.forwardRef<
+  React.ElementRef<typeof TabsPrimitive.Root>,
+  React.ComponentPropsWithoutRef<typeof TabsPrimitive.Root>
+>(({ className, orientation = "horizontal", ...props }, ref) => (
+  <TabsPrimitive.Root
+    ref={ref}
+    data-slot="tabs"
+    data-orientation={orientation}
+    orientation={orientation}
+    className={cn(
+      "group/tabs flex gap-2 data-[orientation=horizontal]:flex-col",
+      className
+    )}
+    {...props}
+  />
+))
+Tabs.displayName = "Tabs"

Also set displayName on TabsList, TabsTrigger, and TabsContent wrappers.

26-118: Consider adding a catch-all route for 404 handling.

The route configuration covers all defined paths but lacks a fallback for unmatched URLs. Users navigating to invalid paths will see a blank page within the AppShell.

♻️ Suggested addition for 404 handling
             <Route
               path={ROUTES.ADMIN}
               element={
                 <Suspense fallback={<PageLoader />}>
                   <AdminPage />
                 </Suspense>
               }
             />
+            <Route
+              path="*"
+              element={
+                <div className="flex h-96 items-center justify-center">
+                  <p className="text-muted-foreground">Page not found</p>

+              }
+            />
           </Route>

26-118: Optional: Consider adding an error boundary for lazy-loaded pages.

If a lazy-loaded chunk fails to load (e.g., network error, deployment mismatch), the app will crash without user feedback. An error boundary around the routes or individual Suspense blocks would improve resilience.

frontend/src/hooks/use-kpis.ts (1)

22-34: Wire React Query's abort signal into api() for cancellation.

api() accepts and properly uses the signal parameter in its fetch call, but the hook currently doesn't forward React Query's abort signal to it. Passing the signal enables proper request cancellation on unmount and query invalidation, preventing stale requests from populating the cache.

♻️ Proposed change
-  return useQuery({
+  return useQuery({
     queryKey: ['kpis', { startDate, endDate, storeId, productId, category }],

109-121: Use stable keys for list items.

Index keys can cause incorrect DOM reuse if ordering changes; prefer a stable identifier (rank, id, or dimension value).

14-36: Align queryKey with the effective search value.

Short search strings are filtered in the queryFn (omitted when < 2 chars) but still included in the queryKey as-is, causing cache fragmentation. Per TanStack Query best practices, the queryKey should reflect the actual parameters sent to the API.

♻️ Suggested refactor
 export function useProducts({
   page,
   pageSize,
   category,
   brand,
   search,
   enabled = true,

96-107: Consider adding the brand filter to the toolbar.

The useProducts hook accepts a brand parameter (Line 56), but the toolbar only includes a category filter. If brand filtering is intended functionality, consider adding a brand filter dropdown to maintain consistency with the hook's capabilities.

♻️ Suggested addition for brand filter

29-33: Type assertion for forecast data could be more defensive.

The type assertion assumes job.result.predictions has a specific shape. Consider adding runtime validation or a type guard to handle unexpected API response formats gracefully.

♻️ Suggested defensive approach
-  const forecastData = job?.result?.predictions as Array<{
-    date: string
-    predicted: number
-  }> | undefined
+  const forecastData = Array.isArray(job?.result?.predictions)
+    ? (job.result.predictions as Array<{ date: string; predicted: number }>)
+    : undefined

137-143: EmptyState visibility logic may need adjustment.

The EmptyState renders when !searchJobId && !isLoading, but after a user searches and then clears the input, searchJobId becomes empty while job data from the previous search may still be displayed (due to React Query caching). Consider showing EmptyState only when there's truly no data to display.

♻️ Suggested logic adjustment
-      {!searchJobId && !isLoading && (
+      {!job && !searchJobId && !isLoading && !error && (

76-78: Consider using a more stable key for list items.

Using array index (idx) as a React key can cause issues if items are reordered or filtered. If dimension_id or a combination of dimension_value and rank is unique, prefer that as the key.

♻️ Suggested key improvement
-                      {data.items.map((item, idx) => (

97-99: Consider formatting the revenue share percentage.

The revenue_share_pct value is displayed directly. If it's a string like "12.5", appending % works, but if it's already formatted or has excessive decimals, consider using a formatter for consistency.

CSS variable names don't match dynamic keys.

The stroke properties use hardcoded CSS variables var(--color-actual) and var(--color-predicted), but chartConfig is keyed by actualKey and predictedKey (which default to 'actual' and 'predicted'). If custom keys are passed, the CSS variables won't exist, and the lines will have no stroke color.

chartConfig[actualKey]?.color || 'var(--color-actual)' for the actual line and
chartConfig[predictedKey]?.color || 'var(--color-predicted)' for the predicted
line. Ensure references use the exact symbols actualKey, predictedKey, and
chartConfig so the fix works with custom keys.

TanStack Table getPageCount returns -1 unknown pagination

💡 Result:

In TanStack Table, table.getPageCount() returns -1 by design when you are doing manual/server-side pagination and you’ve told the table the total page count is unknown.

  • If manualPagination: true, getPageCount() comes from options.pageCount (not from the in-memory data). If you set pageCount: -1, that’s the “unknown page count” sentinel, so getPageCount() will be -1. [1]
  • The docs also note that when you use pageCount: -1, pagination helpers like getCanNextPage() / getCanPreviousPage() will effectively always allow navigation because the table can’t know the end. [2]

How to fix it (pick one)

  1. Provide a real total:
    • Prefer rowCount (total rows) and let the table compute pages, or
    • Provide pageCount directly. [2]
  2. If you’re not actually doing server-side pagination, remove manualPagination: true and use client-side pagination with getPaginationRowModel() so the table can compute page count from the full data set. [1]

Sources: TanStack Table pagination API + guide. [1] [2]


Guard against unknown page counts to prevent negative page indices.

When using manual pagination, table.getPageCount() returns -1 to indicate an unknown page count. This causes two issues: (1) the display shows "Page X of -1" (the || 1 fallback on line 28 doesn't help since -1 is truthy), and (2) the "last page" button on line 82 will call table.setPageIndex(pageCount - 1), setting the index to -2.

The proposed fix correctly disables the button and updates the display, but the onClick handler should also be guarded to prevent invalid state when page count is unknown.

   const pageIndex = table.getState().pagination.pageIndex
   const pageSize = table.getState().pagination.pageSize

- 83, pageCount can be -1 for manual pagination which breaks the display and
makes the "last page" onClick call table.setPageIndex(pageCount - 1) with a
negative value; compute a safe display count (e.g. safePageCount = pageCount > 0
? pageCount : 1) for the "Page X of Y" text and change the last-page Button to
guard its onClick so it only calls table.setPageIndex(pageCount - 1) when
pageCount > 0 (and keep the disabled prop true when pageCount <= 0 or
!table.getCanNextPage()); update uses of pageCount in the last-page Button (and
any related logic) to use these guards so no invalid negative index is set.

@radix-ui/react-accordion Trigger wrapper component ref forwarding pattern best practice documentation v1.2

💡 Result:

Radix’s recommended pattern (works for @radix-ui/react-accordion v1.2.x) is: wrap Accordion.Trigger in your own component, and always forwardRef to the underlying Radix primitive element (because Radix may need to attach a ref for focus/measurement; without ref-forwarding things can break—especially when using asChild). [1] [3]

import * as React from "react";
import * as AccordionPrimitive from "@radix-ui/react-accordion";

export const AccordionTrigger = React.forwardRef<
  React.ElementRef<typeof AccordionPrimitive.Trigger>,
  React.ComponentPropsWithoutRef<typeof AccordionPrimitive.Trigger>
>(({ children, ...props }, forwardedRef) => (
  <AccordionPrimitive.Header>
    <AccordionPrimitive.Trigger ref={forwardedRef} {...props}>
      {children}
    </AccordionPrimitive.Trigger>
  </AccordionPrimitive.Header>
));
AccordionTrigger.displayName = AccordionPrimitive.Trigger.displayName;

If you use asChild on the Trigger (or other parts), the child component you render must also forward its ref, otherwise keyboard focus and other behaviors can fail. [1] [3]

Forward refs on AccordionTrigger to preserve ref-based behavior and Radix compatibility.
This wrapper currently drops refs, which breaks focus management, ref attachment, and asChild compatibility—critical for keyboard navigation and Radix integration per v1.2.x patterns.

HTML button element default type attribute behavior in forms

💡 Result:

In HTML, a <button> with no type attribute defaults to acting like a submit button when it’s associated with a <form> (either inside a form or linked via the form attribute). In other words, clicking it will submit the form unless you explicitly set type="button". This is also the behavior when type is present but empty/invalid. [1], [2]

To avoid accidental submissions for non-submit UI buttons, set:

<button type="button">Click</button>

The HTML Standard defines the missing/invalid default as an “Auto” state that makes the button a submit button under the usual conditions. [3]

Sources: MDN button docs [1], MDN submit button glossary [2], WHATWG HTML Standard (form elements / button) [3].

Add missing React type import (TS compile error).
React.ComponentProps requires importing React. Even with react-jsx mode in tsconfig.app.json, direct namespace references require the import. All other components in the codebase that use React.ComponentProps import React.

an import for React (e.g., import * as React from "react") at the top of the

Guard JSON parsing for non‑JSON/empty responses.

response.json() will throw on non‑JSON bodies (common for errors). That turns a usable HTTP error into a generic parsing exception. Consider a safe parse with fallback to response.text().

💡 Suggested fix

+  let data: unknown = null
+  try {
+    data = await response.json()
+  } catch {
+    const text = await response.text()

update the logic around the call in the function using response.json() (inspect
the variable data and the ApiError construction) to try parsing JSON in a
try/catch, and on failure fall back to await response.text() (or an empty
object) and map that into a ProblemDetail-like shape before throwing new
ApiError(detail.detail || response.statusText, response.status, detail); ensure
you still only throw when !response.ok and preserve ApiError, ProblemDetail and

Avoid losing streaming deltas when finalizing messages.

The complete handler reads streamingContent from its closure, which can be stale if text_delta events arrive before React flushes state. Even though the callback dependency includes [streamingContent], multiple rapid state updates may batch together, causing the closure to capture an outdated value. Use a ref to synchronously buffer incoming content and read from it on complete/error instead.

can lose recent text deltas due to stale streamingContent in its closure; use a

both setStreamingContent(...) and streamingContentRef.current +=

Remove React.ReactNode reference without importing React (TS strict mode error).

The code uses React.ReactNode without importing the React namespace, which will fail TypeScript type checking in strict mode. With jsx: "react-jsx", you can import the type directly instead.

+import { ThemeProvider as NextThemesProvider } from 'next-themes'
