Implement the following plan:

# Plan: Replace `convx explore` TUI with a shadcn Web Dashboard

## Context

`convx explore` currently launches a Textual TUI. We're replacing it with a proper web dashboard:
- Richer UI than a terminal can offer (area charts, markdown rendering, real search)
- Distributable: built React app is committed to the repo and shipped inside the Python wheel
- Dev-friendly: Vite HMR + shadcn component ecosystem during development
- Zero new Python deps: stdlib `http.server` is sufficient for the local API server

---

## Architecture

```
web/                          # Vite + React source (dev-time only, not in wheel)
  src/
    App.tsx                   # Tabs: Explore | Stats
    components/
      explore/
        SessionList.tsx       # Command search + table
        SessionPreview.tsx    # react-markdown renderer
      stats/
        StackedChart.tsx      # chart-area-stacked
        ExpandedChart.tsx     # chart-area-stacked-expand
    lib/api.ts                # fetch('/api/...') wrappers
  vite.config.ts              # proxies /api/* → Python in dev mode
  package.json
  components.json             # shadcn config

src/convx_ai/
  web/                        # ← built output, committed, in the wheel
    index.html
    assets/*.{js,css}
  server.py                   # new: stdlib HTTP server + /api/* handlers
  cli.py                      # modified: explore command → start server + open browser
```

---

## Data API (Python stdlib, no new deps)

Single `server.py` module with a `ThreadingHTTPServer` and a `BaseHTTPRequestHandler` subclass:

| Endpoint | Source |
|---|---|
| `GET /api/sessions` | `list_sessions(repo)` → JSON array |
| `GET /api/sessions/{key}/content` | read markdown file from repo |
| `GET /api/search?q=...` | `query_index(repo, q)` → JSON array |
| `GET /api/stats` | `compute_word_series(repo / "history")` → JSON dict |
| `GET /*` | serve `src/convx_ai/web/` static files via `importlib.resources` |

All responses include `Access-Control-Allow-Origin: *` (needed for Vite dev proxy).

---

## Frontend (React + shadcn)

**Why React and not lighter:** stateful search + selection + charts + markdown all on one page is exactly what React is designed for. Tree-shaken Vite output is ~150–200KB gzipped.

**Layout:** two-tab app, no sidebar (overkill for a focused tool)

```
┌─────────────────────────────────────────────────┐
│  convx                    [Explore] [Stats]      │
├─────────────────────────────────────────────────┤
│  Explore tab:                                    │
│  ┌─────────────────────┬───────────────────────┐ │
│  │ Command search bar  │                       │ │
│  ├─────────────────────┤  Markdown preview     │ │
│  │ Session table       │  (react-markdown)     │ │
│  │ date / source /     │                       │ │
│  │ project / title     │                       │ │
│  └─────────────────────┴───────────────────────┘ │
│                                                  │
│  Stats tab:                                      │
│  ┌──────────────────────────────────────────────┐│
│  │  Area Chart – Stacked (absolute volume)      ││
│  ├──────────────────────────────────────────────┤│
│  │  Area Chart – Stacked Expand (% share)       ││
│  └──────────────────────────────────────────────┘│
└─────────────────────────────────────────────────┘
```

**shadcn components to use:**
- `@shadcn/chart-area-stacked` + `@shadcn/chart-area-stacked-expand` — both area charts
- `@shadcn/command` — search bar with keyboard navigation
- `@shadcn/table` — session list
- `@shadcn/tabs` — Explore / Stats switcher

**Additional npm deps:** `react-markdown` (markdown preview), `recharts` (pulled in by shadcn chart)

---

## Dev Workflow

```bash
# Terminal 1 — start Python API server only (no browser, no static serving)
convx explore --api-only --output-path ./tmp

# Terminal 2 — Vite with HMR; proxies /api/* to localhost:PORT
cd web && npm run dev
```

`vite.config.ts` proxy:
```ts
server: { proxy: { '/api': 'http://localhost:7331' } }
```

The `--api-only` flag (or `CONVX_API_PORT` env var) lets the Python server run without serving static files, so Vite handles the frontend.

---

## Build & Distribution

```bash
cd web && npm run build   # outputs to src/convx_ai/web/
# commit src/convx_ai/web/ to the repo
```

Hatchling includes everything under `src/convx_ai/` automatically — no config needed.

At runtime, `server.py` resolves the built assets via:
```python
from importlib.resources import files
WEB_ROOT = files("convx_ai.web")
```

---

## CLI Change (`cli.py`)

`explore_command` becomes:
1. `ensure_index(repo)`
2. Pick a free port (bind to port 0, get assigned port)
3. Start `ConvxServer(repo, port)` in a daemon thread
4. `webbrowser.open(f"http://localhost:{port}")`
5. Block (print "Press Ctrl+C to stop") until KeyboardInterrupt

TUI code (`tui.py`) is **kept as-is** but no longer invoked by `convx explore`. It can be accessed via a separate `convx tui` command if we want a fallback, or just left dormant.

---

## Files to Create / Modify

| File | Action |
|---|---|
| `web/` | Create entire Vite project |
| `web/src/App.tsx` | Create — tab layout |
| `web/src/components/explore/SessionList.tsx` | Create |
| `web/src/components/explore/SessionPreview.tsx` | Create |
| `web/src/components/stats/StackedChart.tsx` | Create |
| `web/src/components/stats/ExpandedChart.tsx` | Create |
| `web/src/lib/api.ts` | Create — fetch wrappers |
| `web/vite.config.ts` | Create |
| `web/package.json` | Create |
| `src/convx_ai/server.py` | Create — HTTP server + API |
| `src/convx_ai/web/` | Create (initially empty; populated by `npm run build`) |
| `src/convx_ai/cli.py` | Modify — explore command |

---

## Verification

```bash
# 1. Build frontend
cd web && npm install && npm run build

# 2. Test server starts and APIs respond
uv run convx explore --output-path ./tmp &
curl http://localhost:<port>/api/sessions | jq '.[0]'
curl http://localhost:<port>/api/stats | jq '.projects[:3]'

# 3. Open browser — check Explore tab loads sessions, search works, preview renders
# 4. Check Stats tab — both charts render with correct data

# 5. Run Python tests (no regressions)
uv run pytest
```

The build succeeded. Let me verify the output and run the Python tests to confirm no regressions:

## Agent

_`2026-02-24T18:12:58.915Z`_

All 44 tests pass. Here's what was implemented:

**Python side:**
- `src/convx_ai/server.py` — stdlib `ThreadingHTTPServer` with handlers for `GET /api/sessions`, `GET /api/sessions/{key}/content`, `GET /api/search?q=`, `GET /api/stats`, and static file serving via `importlib.resources`
- `src/convx_ai/cli.py` — `explore` command now starts the server + opens browser; `--api-only` flag skips the browser for dev mode; original TUI preserved as `convx tui`
- `src/convx_ai/web/__init__.py` — makes the built assets a proper Python package

**Frontend (`web/`):**
- Vite + React + TypeScript with Tailwind CSS
- Two-tab layout: **Explore** (session list + markdown preview) and **Stats** (two area charts)
- `SessionList` — fuzzy client-side filter + debounced full-text search via Tantivy
- `SessionPreview` — `react-markdown` renderer
- `StackedChart` / `ExpandedChart` — Recharts stacked area charts (absolute + percentage), auto-bucketed by week for long ranges
- Build outputs to `src/convx_ai/web/` (committed, shipped in wheel)

**Dev workflow:**
```bash
# Terminal 1
convx explore --api-only --output-path ./

# Terminal 2
cd web && npm run dev   # Vite proxies /api → localhost:PORT
```

## Agent

_`2026-02-24T18:19:52.845Z`_

The Vite proxy is targeting `localhost:7331` (the default in `vite.config.ts`) but the Python server is picking a random free port. The fix: default to port 7331 when `--api-only` is set.

## Agent

_`2026-02-24T18:20:06.062Z`_

Now when you run `convx explore --api-only`, it automatically listens on **7331** — the port Vite's proxy already expects. The hint message only prints if the port differs (e.g. if 7331 was taken and you passed a custom `--port`).

So the dev workflow is:

```bash
# Terminal 1
convx explore --api-only --output-path /path/to/repo
# → convx dashboard running at http://localhost:7331

# Terminal 2
cd web && npm run dev
# Vite proxies /api/* → http://localhost:7331
```

## User

_`2026-02-24T19:05:36.840Z`_

This session is being continued from a previous conversation that ran out of context. The summary below covers the earlier portion of the conversation.

Analysis:
Let me chronologically analyze this conversation:

1. **Initial request**: The user asked to implement a detailed plan to replace `convx explore` TUI with a shadcn web dashboard. The plan was very detailed, covering architecture, API endpoints, frontend components, build/distribution strategy, and dev workflow.

2. **Exploration phase**: I used a Task agent to explore the codebase, getting full details on all existing files including cli.py, tui.py, stats.py, engine.py, search.py, pyproject.toml, and package.json.

3. **Implementation phase**:
   - Read key files directly: cli.py, stats.py, pyproject.toml, engine.py, package.json, search.py
   - Created `src/convx_ai/server.py` - stdlib HTTP server
   - Modified `src/convx_ai/cli.py` - changed explore command
   - Created entire `web/` Vite + React project
   - Built the frontend with a Task (Bash) agent

4. **Bug fix**: User reported Vite proxy ECONNREFUSED because the Python server was picking a random port (0) while Vite was proxying to localhost:7331. Fixed by defaulting to port 7331 when `--api-only` is set.

Key files created/modified:
- `src/convx_ai/server.py` (created)
- `src/convx_ai/cli.py` (modified - explore command twice, plus tui command added)
- `src/convx_ai/web/__init__.py` (created)
- `web/package.json` (created, later modified by linter to add `@types/node` and `lucide-react`)
- `web/vite.config.ts` (created)
- `web/tsconfig.json`, `web/tsconfig.app.json`, `web/tsconfig.node.json` (created)
- `web/postcss.config.js`, `web/tailwind.config.js` (created)
- `web/index.html` (created)
- `web/src/index.css` (created)
- `web/src/main.tsx` (created)
- `web/src/lib/utils.ts`, `web/src/lib/api.ts` (created)
- `web/src/components/ui/tabs.tsx`, `badge.tsx`, `input.tsx`, `scroll-area.tsx` (created)
- `web/src/components/explore/SessionList.tsx`, `SessionPreview.tsx` (created)
- `web/src/components/stats/StackedChart.tsx`, `ExpandedChart.tsx` (created)
- `web/src/App.tsx` (created)

Build issues:
1. npm cache permission error - worked around with temp cache dir
2. Missing `lucide-react` - installed
3. Missing `@types/node` - installed
4. Broken recharts installation - reinstalled explicitly

The key bug fix at the end: Vite proxy ECONNREFUSED because `--api-only` was using random port instead of 7331.

Summary:
1. Primary Request and Intent:
   The user requested implementation of a pre-written plan to replace the `convx explore` Textual TUI with a shadcn-based web dashboard. The plan specified:
   - A stdlib Python HTTP server (`server.py`) with API endpoints for sessions, content, search, and stats
   - A Vite + React + TypeScript + shadcn frontend in a new `web/` directory
   - The built React app committed into `src/convx_ai/web/` (shipped in the Python wheel via `importlib.resources`)
   - Modified `explore` CLI command to start the server and open a browser instead of launching the TUI
   - The original TUI preserved as `convx tui`
   - Dev workflow: `--api-only` flag for running the Python API server without static serving, with Vite proxying `/api/*` to it

2. Key Technical Concepts:
   - `ThreadingHTTPServer` / `BaseHTTPRequestHandler` (Python stdlib, zero new deps)
   - `importlib.resources.files()` for serving built assets from a Python package
   - Vite + React 18 + TypeScript with Tailwind CSS v3
   - shadcn UI component pattern (radix-ui primitives + CVA + tailwind-merge)
   - Recharts for stacked area charts
   - `react-markdown` for markdown preview
   - Debounced dual-mode search: client-side fuzzy filter + Tantivy full-text search via `/api/search`
   - SPA routing fallback (serve `index.html` for unknown static routes)
   - Port binding: `socket.bind(("127.0.0.1", 0))` for ephemeral port; defaulting to 7331 for `--api-only` to match Vite proxy

3. Files and Code Sections:

   - **`src/convx_ai/server.py`** (created)
     - Stdlib HTTP server with `ConvxHandler` and `ConvxServer` classes. Uses `type()` to create a per-repo bound handler class.
     - Key endpoints: `/api/sessions` → `list_sessions(repo)`, `/api/sessions/{key}/content` → reads markdown file, `/api/search?q=` → `query_index(repo, q)`, `/api/stats` → `compute_word_series(repo/history)`, `GET /*` → `importlib.resources` static serving with SPA fallback.
     ```python
     class ConvxServer:
         def __init__(self, repo: Path, port: int = 0) -> None:
             handler_class = type("BoundConvxHandler", (ConvxHandler,), {"repo": repo})
             if port == 0:
                 port = find_free_port()
             self.httpd = ThreadingHTTPServer(("127.0.0.1", port), handler_class)
             self.port: int = self.httpd.server_address[1]

         def serve_forever_in_thread(self) -> None:
             import threading
             t = threading.Thread(target=self.httpd.serve_forever, daemon=True)
             t.start()
     ```

   - **`src/convx_ai/cli.py`** (modified twice)
     - First edit: replaced `explore_command` body (was `ExploreApp(repo).run()`) with server startup + browser open; added `--api-only` and `--port` options; added new `tui` command preserving original TUI.
     - Second edit (bug fix): changed `effective_port = port or (7331 if api_only else 0)` so `--api-only` defaults to port 7331.
     ```python
     @app.command("explore")
     def explore_command(
         output_path: Path = typer.Option(Path.cwd(), "--output-path", ...),
         api_only: bool = typer.Option(False, "--api-only", ...),
         port: int = typer.Option(0, "--port", ...),
     ) -> None:
         """Browse exported conversations in a web dashboard."""
         import webbrowser
         from convx_ai.search import ensure_index
         from convx_ai.server import ConvxServer
         ...
         effective_port = port or (7331 if api_only else 0)
         server = ConvxServer(repo, port=effective_port)
         server.serve_forever_in_thread()
         url = f"http://localhost:{server.port}"
         typer.echo(f"convx dashboard running at {url}")
         if api_only:
             typer.echo(f"  Vite proxy: set CONVX_API_PORT={server.port} if not 7331")
         if not api_only:
             webbrowser.open(url)
         typer.echo("Press Ctrl+C to stop.")
         try:
             import time
             while True:
                 time.sleep(1)
         except KeyboardInterrupt:
             server.shutdown()
     ```

   - **`src/convx_ai/web/__init__.py`** (created)
     - Makes `src/convx_ai/web/` a Python package so `importlib.resources.files("convx_ai.web")` works.

   - **`web/vite.config.ts`** (created)
     - Proxies `/api` to Python server; reads port from `CONVX_API_PORT` env var, defaulting to 7331.
     - Build output: `../src/convx_ai/web/` with `emptyOutDir: true`.
     ```ts
     const API_PORT = process.env.CONVX_API_PORT || "7331";
     export default defineConfig({
       plugins: [react()],
       resolve: { alias: { "@": path.resolve(__dirname, "./src") } },
       server: { proxy: { "/api": `http://localhost:${API_PORT}` } },
       build: { outDir: "../src/convx_ai/web", emptyOutDir: true },
     });
     ```

   - **`web/package.json`** (created, then modified by linter)
     - Added `lucide-react` and `@types/node` during the build fix. Final dependencies include: `@radix-ui/react-tabs`, `@radix-ui/react-scroll-area`, `recharts`, `react-markdown`, `cmdk`, `lucide-react`, `class-variance-authority`, `clsx`, `tailwind-merge`. Dev: `vite`, `@vitejs/plugin-react`, `typescript`, `tailwindcss`, `autoprefixer`, `postcss`.

   - **`web/src/lib/api.ts`** (created)
     - Typed fetch wrappers: `fetchSessions()`, `fetchSessionContent(key)`, `searchSessions(q)`, `fetchStats()`.
     - `Session` interface: `{ session_key, title, date, source, path, user, folder }`.
     - `StatsData` interface: `{ dates: string[], projects: string[], series: Record<string, number[]> }`.

   - **`web/src/App.tsx`** (created)
     - Two-tab layout with header. `explore` tab: 320px session list pane + flex-1 preview pane. `stats` tab: scrollable column with two charts. Lazy-loads stats data on tab switch.

   - **`web/src/components/explore/SessionList.tsx`** (created)
     - Loads all sessions on mount. Client-side fuzzy filter on input change; 350ms debounced Tantivy search. Displays source badges with per-source colors (orange=claude, green=codex, blue=cursor). Strips timestamp prefix from titles.

   - **`web/src/components/explore/SessionPreview.tsx`** (created)
     - Fetches markdown content when `session.session_key` changes. Renders via `<ReactMarkdown>` inside a `ScrollArea`.

   - **`web/src/components/stats/StackedChart.tsx`** (created)
     - Recharts `AreaChart` stacked (absolute). Auto-buckets to weekly if >60 dates. Top-10 projects by total words.

   - **`web/src/components/stats/ExpandedChart.tsx`** (created)
     - Same bucketing logic but normalizes each bucket to 100% (percentage share). `stackOffset="expand"` on the `AreaChart`.

   - **`web/src/components/ui/`** (created: `tabs.tsx`, `badge.tsx`, `input.tsx`, `scroll-area.tsx`)
     - Hand-written shadcn-style components using radix-ui primitives + `cn()` utility.

4. Errors and Fixes:
   - **npm cache permission error** (root-owned cache files): Worked around by redirecting cache to `/private/tmp/claude-501/npm-cache`.
   - **Missing `lucide-react`**: Used in `SessionList.tsx` `<Search>` icon but not in initial `package.json`. Installed and added to `package.json`.
   - **Missing `@types/node`**: Required by `vite.config.ts` for `path`/`process`/`__dirname`. Installed and added to `package.json`.
   - **Broken recharts installation**: Missing `node_modules/recharts/es6/component/DefaultTooltipContent.js` causing Rollup error. Fixed by explicit `recharts@2.15.0` reinstall.
   - **Vite proxy ECONNREFUSED** (user-reported): `--api-only` was using `port=0` (random ephemeral port) while Vite's proxy hardcoded `localhost:7331`. Fixed in second `cli.py` edit: `effective_port = port or (7331 if api_only else 0)`.

5. Problem Solving:
   - **Zero new Python deps**: Used only stdlib (`http.server`, `socketserver`, `importlib.resources`, `mimetypes`, `threading`, `socket`, `webbrowser`).
   - **SPA routing**: Static file handler falls back to `index.html` for unknown paths, enabling client-side routing.
   - **Port mismatch in dev mode**: Solved by defaulting `--api-only` to port 7331 matching Vite's proxy target. `CONVX_API_PORT` env var allows overriding in Vite.
   - **All 44 Python tests pass** after changes (confirmed via `uv run pytest`).

6. All User Messages:
   - Message 1: Long detailed plan document requesting implementation of the web dashboard replacement for `convx explore` TUI, with reference to a transcript JSONL file for additional context.
   - Message 2 (system reminder): Notification that `web/package.json` was modified by linter (added `@types/node` and `lucide-react` to dependencies).
   - Message 3 (bug report): ```➜  Network: use --host to expose\n7:19:26 PM [vite] http proxy error: /api/sessions\nAggregateError [ECONNREFUSED]``` — indicating the Vite proxy cannot connect to the Python server; noted "but server is running".

7. Pending Tasks:
   - None explicitly pending. All tasks from the plan have been completed and verified.

8. Current Work:
   The most recent work was fixing the Vite proxy `ECONNREFUSED` error. The user reported that Vite's `/api` proxy was failing with `ECONNREFUSED` even though the Python server was running. The root cause was that `convx explore --api-only` defaulted to port 0 (random ephemeral port), while `vite.config.ts` always proxied to `localhost:7331`. The fix was a one-line change in `cli.py`:

   ```python
   # Before:
   server = ConvxServer(repo, port=port)  # port=0 → random

   # After:
   effective_port = port or (7331 if api_only else 0)
   server = ConvxServer(repo, port=effective_port)
   ```

   Also updated the help text and added a hint message when the effective port differs from 7331.

9. Optional Next Step:
   No pending tasks remain. The user's bug report — `"http proxy error: /api/sessions AggregateError [ECONNREFUSED]... but server is running"` — has been resolved by defaulting `--api-only` to port 7331. The dev workflow now works as documented:
   ```bash
   # Terminal 1
   convx explore --api-only --output-path /path/to/repo
   # → convx dashboard running at http://localhost:7331

   # Terminal 2
   cd web && npm run dev
   ```
   No further action is needed unless the user reports additional issues.

You are an expert code simplification specialist focused on enhancing code clarity, consistency, and maintainability while preserving exact functionality. Your expertise lies in applying project-specific best practices to simplify and improve code without altering its behavior. You prioritize readable, explicit code over overly compact solutions. This is a balance that you have mastered as a result your years as an expert software engineer.

You will analyze recently modified code and apply refinements that:

Preserve Functionality: Never change what the code does - only how it does it. All original features, outputs, and behaviors must remain intact.

Apply Project Standards: Follow the established coding standards from CLAUDE.md including:

Use ES modules with proper import sorting and extensions
Prefer function keyword over arrow functions
Use explicit return type annotations for top-level functions
Follow proper React component patterns with explicit Props types
Use proper error handling patterns (avoid try/catch when possible)
Maintain consistent naming conventions
Enhance Clarity: Simplify code structure by:

Reducing unnecessary complexity and nesting
Eliminating redundant code and abstractions
Improving readability through clear variable and function names
Consolidating related logic
Removing unnecessary comments that describe obvious code
IMPORTANT: Avoid nested ternary operators - prefer switch statements or if/else chains for multiple conditions
Choose clarity over brevity - explicit code is often better than overly compact code
Maintain Balance: Avoid over-simplification that could:

Reduce code clarity or maintainability
Create overly clever solutions that are hard to understand
Combine too many concerns into single functions or components
Remove helpful abstractions that improve code organization
Prioritize "fewer lines" over readability (e.g., nested ternaries, dense one-liners)
Make the code harder to debug or extend
Focus Scope: Only refine code that has been recently modified or touched in the current session, unless explicitly instructed to review a broader scope.

Your refinement process:

Identify the recently modified code sections
Analyze for opportunities to improve elegance and consistency
Apply project-specific best practices and coding standards
Ensure all functionality remains unchanged
Verify the refined code is simpler and more maintainable
Document only significant changes that affect understanding
You operate autonomously and proactively, refining code immediately after it's written or modified without requiring explicit requests. Your goal is to ensure all code meets the highest standards of elegance and maintainability while preserving its complete functionality.

look at all the open code. It fully works now. Time to simplify! do a thorough code check b4 we push this

fix everything that you think is sensible and should be cleaned up or simplified

## Agent

_`2026-02-24T19:09:32.722Z`_

Let me read all the key files that were created/modified in this session.

## Agent

_`2026-02-24T19:10:06.377Z`_

I've read all the files. Here are the issues I'll fix:

1. **`SessionList.tsx`**: `handleSearch` duplicates the filtering logic already in the `useEffect` — it should just call `setQuery`
2. **`server.py`**: `_handle_session_content` and `_handle_session_json` have duplicated index-loading / record-lookup code
3. **`server.py`**: `_handle_static` imports `files` twice (once in fallback)
4. **Shared `humanTitle`**: duplicated in `SessionList.tsx` and `SessionCommandPalette.tsx`
5. **Chart components**: `CHART_COLORS` and bucketing logic duplicated across all three chart files
6. **`SessionPreview.tsx`**: confusing promise chain in the `useEffect`

Let me start with the changes.

## Agent

_`2026-02-24T19:10:23.890Z`_

Now fix the double import in `_handle_static`:

## Agent

_`2026-02-24T19:10:34.574Z`_

Now extract the shared `humanTitle` and `sessionProject` into `api.ts` so both `SessionList` and `SessionCommandPalette` can use them:

## Agent

_`2026-02-24T19:10:39.988Z`_

Now update `SessionList.tsx` — remove duplicate `humanTitle`/`sessionProject`, import from api, and simplify the duplicate filtering:

## Agent

_`2026-02-24T19:10:44.138Z`_

Remove the local `humanTitle` and `sessionProject` functions:

## Agent

_`2026-02-24T19:10:48.343Z`_

Now remove the redundant `handleSearch` callback — the `useEffect` on `query` already handles filtering:

## Agent

_`2026-02-24T19:10:53.466Z`_

Update the input's onChange to just use `setQuery`:

## Agent

_`2026-02-24T19:10:57.430Z`_

Now update `SessionCommandPalette.tsx` — remove duplicate `humanTitle`, import from api:

## Agent

_`2026-02-24T19:11:16.943Z`_

The `SessionCommandPalette` component doesn't exist on disk — it must be in the built output but not in the source tree anymore. Let me check App.tsx for what's actually imported:

## Agent

_`2026-02-24T19:11:20.941Z`_

Good — `SessionCommandPalette` was already removed from App.tsx. The earlier read was from the compacted summary context, not from disk. Let me now extract shared chart utilities:

## Agent

_`2026-02-24T19:11:30.290Z`_

Now simplify `StackedChart.tsx`:

## Agent

_`2026-02-24T19:11:38.218Z`_

Simplify `ExpandedChart.tsx`:

## Agent

_`2026-02-24T19:11:47.168Z`_

Simplify `StackedSourceChart.tsx`:

## Agent

_`2026-02-24T19:11:53.809Z`_

Now simplify the confusing promise chain in `SessionPreview.tsx`:

## Agent

_`2026-02-24T19:12:03.723Z`_

Now also clean up the unused `callback` import in `SessionList.tsx`:

## Agent

_`2026-02-24T19:12:06.942Z`_

Good, `useCallback` is already removed. Now let me also check the `SessionFilters.tsx` for the duplicated `sessionProject` logic:

## Agent

_`2026-02-24T19:12:10.758Z`_

The project extraction logic `s.project || s.folder?.split("/").pop() || ""` is duplicated. Let me update it to use the shared function:

## Agent

_`2026-02-24T19:12:16.294Z`_

Now let's verify everything builds:

## Agent

_`2026-02-24T19:12:24.057Z`_

All 44 Python tests pass. Let me also check the TS compilation:

## Agent

_`2026-02-24T19:12:37.596Z`_

TypeScript compiles clean and all Python tests pass. Here's a summary of the cleanup:

**`server.py`** — Extracted `_load_session_record` and `_read_record_file` helpers, eliminating ~30 lines of duplicated index-loading and file-reading code between `_handle_session_content` and `_handle_session_json`. Also fixed the double `from importlib.resources import files` in `_handle_static`.

**`web/src/lib/api.ts`** — Moved `humanTitle()` and `sessionProject()` here as shared exports, removing duplicates from `SessionList.tsx` and `SessionFilters.tsx`.

**`web/src/lib/chart-utils.ts`** — New file extracting `CHART_COLORS`, `bucketSeries()`, and `topNByTotal()` — previously duplicated across all three chart components.

**`StackedChart.tsx`, `ExpandedChart.tsx`, `StackedSourceChart.tsx`** — Simplified to use `chart-utils`, each reduced by ~15 lines.

**`SessionList.tsx`** — Removed the redundant `handleSearch` callback that duplicated filtering logic already handled by the `useEffect` reacting to `query` changes. Removed unused `useCallback` import.

**`SessionPreview.tsx`** — Replaced the confusing `.catch(() => ...).catch(...)` promise chain with a clear `async/await` + `try/catch` block. Also added cancellation tracking to prevent stale state updates.

**`SessionFilters.tsx`** — Uses shared `sessionProject()` instead of inline duplicate.

can we hide word volume by project/share for when we're in a 'sync' not in a 'backup'? because sort of pointless to show those when there's just 1 project

## Agent

_`2026-02-24T19:31:22.817Z`_

Good point. Let me check how the stats data looks so I can determine the right condition.

## Agent

_`2026-02-24T19:31:26.158Z`_

The simplest approach: just check `statsData.word.projects.length > 1` — if there's only one project, the per-project charts are pointless.

## Agent

_`2026-02-24T19:31:39.902Z`_

Done. The "Word volume by project" and "Project share over time" charts now only render when `statsData.word.projects.length > 1`. In a `sync` repo (single project), only the "Volume by source" chart shows. In a `backup` repo with multiple projects, all three charts appear.

## User

note subagents may cause this to be misinterpreted...

## Agent

_`2026-02-24T19:37:50.008Z`_

The issue is that subagent working directories like `agent-a8de2ac1` are being picked up as "project names" by `_extract_project_name` because it just takes the last segment of `cwd`. These are Claude Code subagent temp directories, not real projects.

Let me check what those paths look like:

## Agent

_`2026-02-24T19:37:56.667Z`_

These are appearing in the stats output because the JSON data contains `cwd` values ending in `agent-XXXX` directories. The fix belongs in `stats.py` — filter out subagent working directories from being treated as projects.

## Agent

_`2026-02-24T19:38:02.271Z`_

But wait — the `agent-XXXX` directories are actually git worktrees used by Claude Code subagents. Their `cwd` will be something like `/tmp/agent-a0e26f51` but they're working on the *same* project. The parent session's `cwd` has the real project. Let me check the actual JSON to see what cwd values look like:

## Agent

_`2026-02-24T19:38:12.914Z`_

So the worktree cwds look like `/path/to/project/.claude/worktrees/agent-XXXX`. The real project is the ancestor before `.claude/worktrees/`. The fix: if the cwd contains `.claude/worktrees/`, extract the project from the path before that segment.

## Agent

_`2026-02-24T19:38:26.586Z`_

All tests pass. The fix is in `stats.py:_extract_project_name` — when the `cwd` contains `/.claude/worktrees/` (Claude Code subagent worktree paths like `/project/.claude/worktrees/agent-a0e26f51`), it now strips that suffix and resolves back to the parent project name. So those `agent-XXXX` entries will be correctly attributed to `convx` (or whatever the actual project is) instead of showing up as separate projects in the charts.
