-## Task 6: Jobs Page Redesign — Report
-
-### Changes Made
-
-**`templates/jobs.html`** — Complete rewrite from table layout to responsive card grid.
-
-- Page heading changed from "All Jobs" to "Processing Jobs"
-- Card grid layout with responsive columns: 1 col (mobile), 2 col (640px+), 3 col (1024px+)
-- Each job card contains:
-  - Thumbnail image from `/preview/thumb/<job_id>` with SVG placeholder fallback on error
-  - Status badge (top-right corner) using `.badge-*` classes: success (COMPLETED), info (RUNNING), warning (PENDING), error (FAILED), neutral (CANCELLED)
-  - Truncated job ID (12 chars + ellipsis) with copy-to-clipboard button (green checkmark feedback)
-  - Video filename extracted from `job.video_path`
-  - Thin 4px progress bar with model count and percentage
-  - Relative timestamp (e.g. "2 minutes ago") with auto-update every 60s
-  - "View Details" link to `/status/<job_id>`
-- Empty state with film-strip SVG icon, "No jobs yet" heading, and "Upload a video" CTA button
-- Scoped `<style>` block with design system tokens (no new CSS in `style.css`)
-- Inline `<script>` for relative time formatting and clipboard copy functionality
-
-### Verification
-
-- Template loads without Jinja2 errors
-- Flask `/jobs` endpoint returns 200 OK
-- Empty state renders correctly (no jobs by default)
-- All required elements present in rendered HTML: page header, grid, card structure, thumbnails, badges, copy button, progress bars, relative times, empty state, CTA button
-
-### Commit
-
-`b1170f4` — `feat(ui): jobs page — card grid with badges and thumbnails`
-
----
-
-### Review Fixes (3 findings)
-
-1. **Non-semantic card container** — Changed `<div class="card job-card">` → `<article class="card job-card">` (and closing tag) for better screen reader navigation.
-
-2. **`onclick` on copy button** — Removed inline `onclick="copyJobId(this, '{{ job.job_id }}')"` attribute; added `data-job-id="{{ job.job_id }}"` for identification; moved copy logic to `addEventListener('click', ...)` in the `<script>` block using `document.querySelectorAll('.copy-btn')`.
-
-3. **Gradient on progress bar** — Replaced `linear-gradient(90deg, var(--color-primary-500), var(--color-primary-400))` with solid `var(--color-primary-500)` to match flat design system.

+# Feedmill Recounter — Web UI Redesign
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Redesign the feedmill_recounter web UI from a basic dark theme to a clean, modern, user-friendly interface with live preview of processing, using a Flat Design system with teal primary (#0D9488), orange accent (#EA580C), Plus Jakarta Sans font, and dark-mode-ready tokens.
+
+**Current State:** 4 templates (base.html, index.html, status.html, jobs.html), 1 CSS file (34 lines), no JS file. App.py serves on port 9000.
+
+**Tech Stack:** HTML, CSS, vanilla JS (no new Python dependencies), Flask templates
+
+---
+
+## Global Constraints
+
+- Python >= 3.10 (uses `X | Y` union syntax)
+- No new Python dependencies for UI redesign (Flask + OpenCV already installed)
+- Web UI port 9000 via `WEB_PORT` env variable
+- All model weights in `models/` directory; `.engine` files are gitignored
+- Class filtering by name string (`"sack"`, `"box"`, `"truck"`), not numeric ID
+- CSS uses Flat Design with teal primary (#0D9488), orange accent (#EA580C)
+- Font: Plus Jakarta Sans (Google Fonts CDN)
+- Dark-mode-ready CSS custom properties (light mode default, easy dark swap)
+- Accessible: skip-link, focus rings, semantic HTML, ARIA where needed
+- Responsive: mobile-first, works on 320px to 1920px+
+- No JS frameworks — vanilla JS only
+- Live preview: pipeline emits JPEG frame every Nth frame → Job.latest_frame → served as base64 in API → JS polls and displays
+
+---
+
+## File Structure (changes only)

+```
+
+---
+
+### Task 1: Design System Foundation
+
+**Files:**
+- Rewrite: `feedmill_recounter/static/style.css`
+- Rewrite: `feedmill_recounter/templates/base.html`
+
+**Requirements:**
+1. `style.css` — complete rewrite with:
+   - CSS custom properties (design tokens) for colors, spacing, typography, radii, shadows
+   - Teal primary: `--color-primary: #0D9488` (with 50-900 scale shades)
+   - Orange accent: `--color-accent: #EA580C` (with 50-900 scale shades)
+   - Neutrals: `--color-neutral-50` through `--color-neutral-900`
+   - Status colors: success (#16A34A), warning (#F59E0B), error (#DC2626), info (#0EA5E9)
+   - Typography: `--font-sans: 'Plus Jakarta Sans', system-ui, sans-serif`
+   - Spacing scale: `--space-1` (4px) through `--space-16` (64px)
+   - Border radius: `--radius-sm` (6px), `--radius-md` (8px), `--radius-lg` (12px), `--radius-xl` (16px)
+   - Shadows: `--shadow-sm`, `--shadow-md`, `--shadow-lg`
+   - Transitions: `--transition-fast` (150ms), `--transition-normal` (250ms)
+   - Base reset/normalize
+   - `.container` max-width 1200px centered
+   - Skip-link (visually hidden, visible on focus)
+   - Focus ring: 2px solid primary, offset 2px
+   - Button styles: primary (teal), secondary (outline), accent (orange), ghost
+   - Card component: `.card` with padding, border-radius, shadow, border
+   - Badge component: `.badge` with status variants
+   - Form elements: inputs, selects, labels with consistent styling
+   - Responsive breakpoints: 640px, 768px, 1024px, 1280px
+
+2. `base.html` — rewrite with:
+   - `<!DOCTYPE html>`, `<html lang="en">`
+   - `<meta charset="UTF-8">`, `<meta name="viewport" content="width=device-width, initial-scale=1.0">`
+   - Google Fonts link for Plus Jakarta Sans (weights 400, 500, 600, 700)
+   - Skip-link: `<a href="#main" class="skip-link">Skip to content</a>`
+   - Semantic `<header>` with `<nav>` containing Upload and Jobs links
+   - `<main id="main">` with `{% block content %}{% endblock %}`
+   - `<footer>` with project credit
+   - Link to `style.css`
+   - `{% block head %}{% endblock %}` for page-specific head content (scripts, meta)
+
+**Commit:** `feat(ui): design system foundation — CSS tokens, base template`
+
+---
+
+### Task 2: Upload Page Redesign
+
+**Files:**
+- Rewrite: `feedmill_recounter/templates/index.html`
+- Create: `feedmill_recounter/static/app.js` (drag-drop + video preview logic)
+
+**Requirements:**
+1. `index.html` — rewrite with:
+   - Page heading: "Upload & Analyze"
+   - Drag-and-drop zone: `.upload-zone` with dashed border, icon, text "Drag video here or click to browse"
+   - Hidden file input triggered by zone click
+   - Video preview: `<video>` element showing selected file (controls, muted)
+   - File info display: name, size, duration (if probed)
+   - Model selection section: grid of `.model-card` elements
+   - Each model card: checkbox, model name, known classes as badges, class-filter dropdown
+   - "Select All" / "Deselect All" toggle for models
+   - Submit button: "Start Analysis" (primary, disabled until video + model selected)
+   - Loading state on submit: button text changes to "Starting..."
+
+2. `app.js` — create with:
+   - `initUploadZone()`: click-to-browse, drag-drop handlers, file validation
+   - `initVideoPreview()`: FileReader → `<video>` src, display file info
+   - `initModelCards()`: select-all toggle, enable/disable submit based on selections
+   - `initFormSubmit()`: disable button on submit, show loading state
+   - Progressive enhancement: works without JS (basic file input still functions)
+
+**Commit:** `feat(ui): upload page — drag-drop, video preview, model cards`
+
+---
+
+### Task 3: Preview Backend
+
+**Files:**
+- Create: `feedmill_recounter/src/preview.py`
+- Modify: `feedmill_recounter/app.py` — add preview routes
+
+**Requirements:**
+1. `preview.py` — create with:
+   - `probe_video(video_path: str) -> dict`: returns {width, height, fps, duration, frame_count} using cv2
+   - `extract_thumbnail(video_path: str, output_path: str, time_sec: float = 1.0) -> str`: extracts a single frame as JPEG, returns path
+   - `extract_sample_frames(video_path: str, output_dir: str, count: int = 6) -> list[str]`: extracts evenly-spaced frames as JPEGs, returns paths
+
+2. `app.py` — add routes:
+   - `GET /preview/thumb/<job_id>` — serves thumbnail JPEG for a job's video (extract on first request, cache in job output_dir)
+   - `GET /api/jobs/<job_id>/samples` — returns JSON array of sample frame paths (extract if not cached)
+   - `GET /api/jobs/<job_id>/frame` — returns current latest_frame as JPEG (for live preview during processing)
+
+**Commit:** `feat(api): video preview endpoints — thumbnail, sample frames, live frame`
+
+---
+
+### Task 4: Status Page Redesign
+
+**Files:**
+- Rewrite: `feedmill_recounter/templates/status.html`
+- Modify: `feedmill_recounter/static/app.js` — add polling + live preview logic
+
+**Requirements:**
+1. `status.html` — rewrite with:
+   - Job header: job ID, status badge (color-coded), created time
+   - Progress section: animated progress bar with percentage label, current model name
+   - Live preview section: `<img>` element that polls `/api/jobs/<id>/frame` every 2s, shows annotated frame during processing
+   - Video thumbnail: extracted from original video
+   - Results section: grid of result cards (not table)
+   - Each result card: model name, loading/unloading/net counts as big numbers, batch count, duration, download button
+   - Error display: alert-style error message if job failed
+   - Auto-refresh: JS polls `/api/jobs/<id>` every 2s, updates progress bar + status badge + live preview + results
+
+2. `app.js` — add:
+   - `initStatusPage()`: starts polling loop
+   - `updateProgressBar(progress)`: animates width
+   - `updateLivePreview(jobId)`: fetches `/api/jobs/<id>/frame`, updates `<img>` src
+   - `updateResults(results)`: renders result cards
+   - Polling stops when status is COMPLETED, FAILED, or CANCELLED
+
+**Commit:** `feat(ui): status page — progress bar, live preview, result cards, polling`
+
+---
+
+### Task 5: Live Annotated Frame Emission
+
+**Files:**
+- Modify: `feedmill_recounter/src/job.py` — add `latest_frame: bytes | None` field to Job
+- Modify: `feedmill_recounter/src/pipeline.py` — emit JPEG frame every 10th frame to callback
+
+**Requirements:**
+1. `job.py` — add to `Job` dataclass:
+   - `latest_frame: bytes | None = None` field
+   - Thread-safe update: worker sets `job.latest_frame = jpeg_bytes` under `self._lock`
+
+2. `pipeline.py` — modify `run_pipeline()`:
+   - Accept optional `frame_callback: Callable[[bytes], None] | None = None` parameter
+   - Every 10th frame (frame_idx % 10 == 0), encode frame as JPEG bytes via `cv2.imencode('.jpg', viz)`
+   - Call `frame_callback(jpeg_bytes)` if provided
+   - In `job.py` `_run_job()`, pass callback that sets `job.latest_frame`
+
+**Commit:** `feat(pipeline): emit live annotated frames for preview`
+
+---
+
+### Task 6: Jobs Page Redesign
+
+**Files:**
+- Rewrite: `feedmill_recounter/templates/jobs.html`
+
+**Requirements:**
+1. `jobs.html` — rewrite with:
+   - Page heading: "Processing Jobs"
+   - Empty state: illustration + "No jobs yet" + "Upload a video" CTA
+   - Card grid layout (responsive: 1 col mobile, 2 col tablet, 3 col desktop)
+   - Each job card:
+     - Thumbnail (extracted from video, or placeholder)
+     - Status badge (top-right corner)
+     - Job ID (truncated, with copy button)
+     - Video filename
+     - Model count + progress bar (thin)
+     - Created time (relative: "2 minutes ago")
+     - "View Details" link
+   - Sort: newest first (already default from job_queue.list_jobs)
+
+**Commit:** `feat(ui): jobs page — card grid with badges and thumbnails`
+
+---
+
+### Task 7: Accessibility, Responsive, Polish
+
+**Files:**
+- Modify: `feedmill_recounter/static/style.css` — add responsive utilities, a11y enhancements
+- Modify: `feedmill_recounter/static/app.js` — add keyboard handlers, ARIA updates
+- Modify: `feedmill_recounter/templates/*.html` — add ARIA attributes where needed
+
+**Requirements:**
+1. CSS additions:
+   - `@media (prefers-reduced-motion: reduce)` — disable animations
+   - `@media (prefers-color-scheme: dark)` — dark mode token overrides
+   - Print styles: `@media print` — hide nav, buttons, show content
+   - `.sr-only` utility for screen-reader-only text
+   - Focus-visible styles for keyboard navigation
+
+2. JS additions:
+   - Keyboard: Enter/Space on upload zone triggers file input
+   - ARIA: `aria-live="polite"` on progress region, `aria-busy` during processing
+   - Announce status changes to screen readers
+
+3. HTML fixes:
+   - All images have `alt` text
+   - All interactive elements have accessible names
+   - Form inputs have associated labels
+   - Status changes announced via `aria-live`
+
+**Commit:** `fix(ui): accessibility, responsive, polish pass`
+
+---
+
+### Task 8: Final Verification
+
+**Files:** None (verification only)
+
+**Requirements:**
+1. Run existing tests: `cd /home/jetson/feedmill_semarang_project/feedmill_recounter && python -m pytest tests/ -v`
+2. Verify Flask app starts: `python -c "from app import app; print('OK')"`
+3. Verify templates render: manual check or curl localhost:9000
+4. Verify CSS loads: check static/style.css served correctly
+5. Verify JS loads: check static/app.js served correctly
+6. Verify all routes work: /, /jobs, /status/<id>, /preview/thumb/<id>, /api/jobs, /api/jobs/<id>, /api/jobs/<id>/frame
+
+**Commit:** none (verification only)

+# Models Cleanup & Truck Filter Implementation Plan
+
+> **For agentic workers:** REQUIRED SUB-SKILL: Use superpowers:subagent-driven-development (recommended) or superpowers:executing-plans to implement this plan task-by-task. Steps use checkbox (`- [ ]`) syntax for tracking.
+
+**Goal:** Clean up the models directory, create TensorRT .engine files for all .pt models, add a "truck only" filter option, and fix the onnxruntime dependency issue.
+
+**Architecture:** One script to export all .pt models to .engine, one cleanup step to remove duplicates, one template change to add truck filter, one fix to handle missing onnxruntime gracefully.
+
+**Tech Stack:** Python, ultralytics YOLO, TensorRT (via ultralytics export), Flask templates
+
+**Spec:** User request — April 2026
+
+---
+
+## Context
+
+### Current State
+- **Models directory:** 16 files (7 `.pt`, 7 `.onnx`, 0 `.engine`)
+- **Duplicate file:** `v4-best (1).pt` (same size as `v4-best.pt`) — needs removal
+- **No .engine files:** All models run as .pt or .onnx; .engine (TensorRT) would be faster on Jetson
+- **Recent job failure:** `job-e4e73c85` failed with `No module named 'onnxruntime'` when trying to run the second .onnx model
+
+### Filtering Explained
+The class filter dropdown in the upload page controls which object classes the YOLO model detects:
+
+| Filter Option | Value | Behavior |
+|---------------|-------|----------|
+| Use model defaults | `"default"` | Uses `model_config.known_classes` from `KNOWN_MODEL_CLASSES` map (e.g., `["person", "sack"]` for karung model) |
+| sack only | `"sack"` | Only detects sack objects |
+| box only | `"box"` | Only detects box objects |
+| sack + box | `"sack,box"` | Detects both sack and box |
+| **truck only** | (missing) | Should detect only truck objects |
+| all classes | `"all"` | No filtering — model detects everything it was trained on |
+
+**Key difference:** "Use model defaults" applies the known class filter from the registry. "All classes" passes `None` as the filter, letting the model detect all its trained classes. The pipeline code at `src/pipeline.py:92-94` shows:
+```python
+effective_filter = class_filter or (
+    model_config.known_classes if model_config.known_classes else None
+)
+```
+
+### Onnxruntime Issue
+The error `No module named 'onnxruntime'` occurs when the pipeline tries to load `.onnx` models. Two options:
+1. Install onnxruntime (`pip install onnxruntime`)
+2. Convert .onnx models to .engine (TensorRT) which doesn't need onnxruntime
+
+Since we're creating .engine files anyway, option 2 is preferred for Jetson.
+
+---
+
+## Global Constraints
+
+- Python >= 3.10
+- Platform: Jetson (ARM64) with CUDA
+- ultralytics already installed
+- TensorRT available on Jetson
+- .engine files are gitignored
+- Models directory: `./models/`
+
+---
+
+### Task 1: Remove Duplicate Model File
+
+**Files:**
+- Delete: `models/v4-best (1).pt`
+
+**Requirements:**
+- Remove the duplicate `v4-best (1).pt` file (same content as `v4-best.pt`)
+- Verify `v4-best.pt` still exists after deletion
+
+- [ ] **Step 1: Remove duplicate file**
+
+```bash
+rm "/home/jetson/feedmill_semarang_project/feedmill_recounter/models/v4-best (1).pt"
+```
+
+- [ ] **Step 2: Verify v4-best.pt still exists**
+
+```bash
+ls -la /home/jetson/feedmill_semarang_project/feedmill_recounter/models/v4-best.pt
+```
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add -A && git commit -m "chore: remove duplicate v4-best (1).pt model file"
+```
+
+---
+
+### Task 2: Create TensorRT .engine Files for All .pt Models
+
+**Files:**
+- Create: `scripts/export_engines.py`
+
+**Requirements:**
+- Script iterates over all `.pt` files in `models/`
+- For each .pt file, export to .engine using `model.export(format='engine', device=0, half=True, imgsz=640)`
+- Skip if .engine already exists
+- Handle export failures gracefully (log warning, continue)
+- Print summary of successful/failed exports
+
+- [ ] **Step 1: Create export script**
+
+```python
+#!/usr/bin/env python3
+"""Export all .pt models to TensorRT .engine format for Jetson."""
+
+from pathlib import Path
+from ultralytics import YOLO
+
+MODELS_DIR = Path(__file__).resolve().parent.parent / "models"

+    success = 0
+    failed = 0
+    skipped = 0
+
+    for pt_path in pt_files:

+
+    print(f"\nSummary: {success} exported, {skipped} skipped, {failed} failed")
+
+if __name__ == "__main__":
+    main()
+```
+
+- [ ] **Step 2: Run the export script**
+
+```bash
+cd /home/jetson/feedmill_semarang_project/feedmill_recounter
+python scripts/export_engines.py
+```
+
+- [ ] **Step 3: Verify .engine files created**
+
+```bash
+ls -la models/*.engine

+- [ ] **Step 4: Commit**
+
+```bash
+git add scripts/export_engines.py && git commit -m "feat: add TensorRT engine export script"

+### Task 3: Add "truck only" Filter Option
+
+**Files:**
+- Modify: `templates/index.html:255` — add truck only option
+
+**Requirements:**
+- Add `<option value="truck">truck only</option>` after the "sack + box" option
+- The value `"truck"` will be split into `["truck"]` by the existing filter logic in `app.py:72`
+
+- [ ] **Step 1: Add truck only option to template**
+
+In `templates/index.html`, after line 254 (`<option value="sack,box">sack + box</option>`), add:
+
+```html
+<option value="truck">truck only</option>
+```
+
+- [ ] **Step 2: Verify template renders**
+
+```bash
+curl -s http://192.168.192.93:9000/ | grep "truck only"
+```
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add templates/index.html && git commit -m "feat: add truck only filter option to upload page"
+```
+
+---
+
+### Task 4: Handle Missing onnxruntime Gracefully
+
+**Files:**
+- Modify: `src/pipeline.py:95` — catch import error and suggest .engine
+
+**Requirements:**
+- When loading a .onnx model, if onnxruntime is not installed, raise a clear error message
+- Suggest the user either install onnxruntime or use the .engine version of the model
+- This prevents cryptic `ModuleNotFoundError` deep in the stack
+
+- [ ] **Step 1: Add onnxruntime check in pipeline.py**
+
+In `src/pipeline.py`, before line 95 (`shared_model = YOLO(model_config.path)`), add:
+
+```python
+    # Check onnxruntime for .onnx models
+    if model_config.path.endswith(".onnx"):
+        try:
+            import onnxruntime  # noqa: F401
+        except ImportError:
+            raise RuntimeError(
+                f"onnxruntime is not installed. Cannot load .onnx model '{model_config.filename}'. "
+                f"Either install it (pip install onnxruntime) or use the .engine version of this model."
+            )
+```
+
+- [ ] **Step 2: Run tests**
+
+```bash
+cd /home/jetson/feedmill_semarang_project/feedmill_recounter
+python -m pytest tests/test_pipeline.py -v
+```
+
+- [ ] **Step 3: Commit**
+
+```bash
+git add src/pipeline.py && git commit -m "fix: graceful error when onnxruntime missing for .onnx models"
+```
+
+---
+
+### Task 5: Update Model Registry for .engine Files
+
+**Files:**
+- Modify: `src/model_registry.py:9-16` — add .engine entries to KNOWN_MODEL_CLASSES
+
+**Requirements:**
+- Add entries for .engine files so they get proper known_classes
+- Since .engine files have the same stem as .pt files, the existing mapping should work
+- But verify that .engine files are picked up by `scan_models()` (they should be, since `MODEL_EXTENSIONS` includes `.engine`)
+
+- [ ] **Step 1: Verify .engine files are scanned**
+
+```python
+cd /home/jetson/feedmill_semarang_project/feedmill_recounter
+python3 -c "from src.model_registry import scan_models; models = scan_models('./models'); print([m.filename for m in models if m.filename.endswith('.engine')])"
+```
+
+- [ ] **Step 2: If not scanned, check MODEL_EXTENSIONS includes .engine**
+
+The current code already has `MODEL_EXTENSIONS = {".pt", ".onnx", ".engine"}` — no change needed.
+
+- [ ] **Step 3: Verify known_classes are assigned to .engine models**
+
+```python
+python3 -c "from src.model_registry import scan_models; models = scan_models('./models'); [(print(m.filename, m.known_classes)) for m in models if m.filename.endswith('.engine')]"
+```
+
+- [ ] **Step 4: No commit needed if everything works — this is verification only**
+

+
+## Summary of Changes
+
+| Task | File | Change |
+|------|------|--------|
+| 1 | `models/v4-best (1).pt` | DELETE |
+| 2 | `scripts/export_engines.py` | CREATE — export script |
+| 3 | `templates/index.html` | ADD — truck only filter option |
+| 4 | `src/pipeline.py` | ADD — onnxruntime check |
+| 5 | `src/model_registry.py` | VERIFY only — .engine already supported |
+
+---
+
+## Execution Order
+
+1. Task 1 (quick cleanup)
+2. Task 3 (quick template fix)
+3. Task 4 (quick pipeline fix)
+4. Task 5 (verification)
+5. Task 2 (export engines — longest, can run in background)
+
+Tasks 1, 3, 4 can be done in parallel. Task 2 should be last since it takes time.
