This commit introduces a specialized visualization for ADAS radar data and significantly
improves the Data Explorer's responsiveness at small window dimensions.
Key Changes:
- ADAS Visualization: Replaced the horizontal AG Grid for the ADAS tab with a custom
Vertical Property View. This uses a card-based layout with clean Key-Value tables,
optimizing for high-column counts and narrow panels.
- Layout Optimizations:
- Reduced minimum window dimensions for the Data Explorer from 400x300 to 250x200.
- Implemented horizontal scrolling for the tab navigation row to prevent UI breakage
at narrow widths.
- Added 'flex-shrink-0' guards to the panel header and tabs to ensure they remain
visible and stable during vertical resizing.
- UI Refinement: Cleaned up the ADAS view by removing redundant property IDs from
headers and centering all data within a structured 2-column grid.
- Documentation:
- Updated the /intel folder (readme.md, context.md, GEMINI.md) to reflect new features.
- Added "Rationale" comments to source code (index.html, dataExplorer.js) to document
architectural decisions and prevent future UI regressions.
Fixes: #ADAS-Explorer-Overhaul
- Decoupled 'God Mode' from GridStack into a standalone floating fixed overlay.
- Extracted 'makeDraggableAndResizable' utility with persistent localStorage memory.
- Implemented "Soft-Reload" for GridStack: restores panel positions by gs-id without destructive DOM replacement.
- Added viewport-aware "Rescue Logic" to pull off-screen panels back into view on window resize.
- Re-architected God Mode auto-hide sequence (5s delay + 3s countdown with visual warning).
- Implemented 'Auto-Focus' logic: clicking any floating panel populates it to the front (z-index: 40).
- Hardened all p5.js sketches with 0-width guards to prevent crashes during container shifts.
- Cleaned up redundant UI text overlays and unified the visual presentation.
- Extracted drag/resize logic from Data Explorer into reusable `ui.js` utility.
- Migrated Zoom Sketch from GridStack into a free-floating, draggable, and resizable `z-30` overlay (default size 900x455).
- Restored and optimized auto-hide timing lifecycle for Close-Up mode:
- 0-5s: Clean freeze for data inspection without hovering.
- 5-8s: Fading visual countdown warning prior to panel closure.
- Implemented state flag `zoomPanelExplicitlyClosed` guaranteeing the "X" button correctly masks rapid re-triggers.
- Bound 'g' toggle shortcut to aggressively wipe/close panels when exiting God Mode entirely.
- Added visual "Mouse pointer Out of Bounds" overlay when cursor exits main radar canvas.
- Implemented GridStack.js as the core dashboard manager, enabling responsive dragging and resizing of the Radar, Video, and SpeedGraph panels.
- Replaced global windowResized events with debounced ResizeObserver instances attached to the specific panel containers.
- Fixed a massive memory leak in p5.js sketches by explicitly calling .remove() on old Graphics buffers before recreation.
- Optimized zoomSketch.js by removing destructive canvas teardown calls from radarSketch and using smoothed camera coordinates for tooltip bounding logic.
- Patched tooltip overflow bugs in drawUtils.js and speedGraphSketch.js to intelligently clamp within panel edges, even in narrow columns.
- Disabled native p5 windowResized triggers to prevent double-firing when moving the web app across multiple monitors.
- Expanded start screen card and drop zone visuals for better accessibility.
- Implemented a global #global-drag-overlay that appears on drag over the entire window.
- Attached drag-and-drop listeners to document.body for universal file loading.
- Refined dragCounter logic to prevent overlay flickering during child element transit.
- Added null check for appState.vizData in sync.js to prevent TypeError during visualization reset.
- Implemented key validation guards in db.js manual offset functions to avoid IndexedDB DataErrors.
- Updated fileLoader.js to bypass manual offset lookup when no JSON filename is available.
- Added regression test 'tests/regression_video_only.test.js' to verify stable partial load paths.

fix: resolve console warnings and add configurable debug logging
This commit addresses active console warnings and reduces logging noise in the SpeedGraph component.
### Changes:
- **index.html**: Fixed `[Deprecation]` warning by replacing the non-standard `-webkit-appearance: slider-vertical` with modern CSS properties (`writing-mode: vertical-lr; direction: rtl;`).
- **speedGraphSketch.js**:
- Resolved `pop() was called without matching push()` error by removing an orphaned `pop()` call in [drawStaticGraphToBuffer](cci//file:///d:/Work/Repo/refactor/steps/src/p5/speedGraphSketch.js:41:2-295:4).
- Muted "Density Info" messages by gating them behind a configurable debug flag.
- **debug.js**: Added a new [speedGraph](cci:1://file:///d:/Work/Repo/refactor/steps/src/p5/speedGraphSketch.js:7:0-538:2) flag (defaulted to `false`) to `debugFlags` to allow selective enabling of SpeedGraph logs.
IMPROVEMENTS:
- **utils.js**: Enhanced [extractTimestampInfo](cci//file:///d:/Work/Repo/refactor/steps/src/utils.js:36:0-70:1) with a robust, prefix-agnostic regular expression. It now identifies `YYYYMMDD_HHMMSS` and `DDMMYYYY_HHMMSS` patterns anywhere in a filename, enabling support for generic camera names like `cam_20260312_163310` or raw recordings.
- **dom.js**: Decoupled persistent overlays and debug diagnostics from mandatory video date-time metadata. The dashboard now remains fully functional even when loading generic video files (e.g., `output.mp4`).
- **Standardized Epoch Fallback**: Implemented a unified time-anchoring logic. If a filename lacks date-time information, the system now defaults to **January 1, 1970 (Unix Epoch)**, ensuring the absolute time clocks and sync diagnostics proceed without error or disappearance.
- **Bug Fixes**: Corrected syntax errors and structural scoping issues in the [updateDebugOverlay](cci:1://file:///d:/Work/Repo/refactor/steps/src/dom.js:200:0-291:1) function that were causing diagnostics to display inconsistently.
This commit refactors the initialization phase of the Visualizer to act as a Single Page Application (SPA). A persistent workspace shell is now initially hidden behind a "Data Synchronizer" Start Screen, which handles file ingestion before seamlessly revealing the canvas.
Part 1: Implement SPA Start Screen Modal and Data Routing
* steps/index.html: Added the full-screen `start-screen-modal` overlay to intercept the user on load. Removed text placeholders inside the video and canvas containers since the workspace is now exclusively visible when populated.
* steps/src/dom.js: Exported references for the new modal, drop zone, and primary load buttons.
* steps/src/main.js: Routed standard drag-and-drop and click events to target the new Start Screen elements rather than the legacy footer buttons, initiating the existing file pipeline.
Part 2: Integrate Loading Progress Natively
* steps/index.html: Added a hidden `start-progress-container` directly inside the Start Screen card to prevent overlapping popups.
* steps/src/dom.js: Exported references to the native progress bar and text elements.
* steps/src/modal.js: Refactored `showLoadingModal`, `updateLoadingModal`, and `hideModal` to dynamically route progress updates. If the Start Screen is active, it renders the inline progress bar and disables background buttons rather than spawning the generic popup modal.
* steps/src/fileLoader.js: Updated `processFilePipeline` to fully dismiss the `start-screen-modal` upon successful data ingestion and precomputation, seamlessly transitioning the user.
Part 3: Replicate Accessibility and Theme Controls
* steps/index.html: Duplicated the Quick Start Guide, Codebase Overview, What's New, and Theme Toggle buttons, positioning them in the top-right corner of the Start Screen. Also fixed a `-webkit-appearance` CSS warning on the range slider.
* steps/src/dom.js: Exported references for the new accessibility buttons and theme toggle SVGs.
* steps/src/ui.js: Attached existing `toggleGuideModal`, `toggleCodebaseModal`, and `toggleChangelogModal` event listeners to the new replicated buttons, granting users access to documentation before data load.
* steps/src/theme.js: Updated `initializeTheme()` so switching the theme from either the workspace or the Start Screen bidirectionally syncs the Light/Dark SVGs on both buttons simultaneously.
Refactors the rendering logic for both main radar and zoom views to support
high-refresh-rate monitors and 4K displays without performance loss.
Key Changes:
1. Performance & Display:
- Uncapped Frame Rate: Set `p.frameRate(144)` in both sketches. This removes
artificial throttling on high-refresh monitors (75Hz+), eliminating
beat-frequency judder.
- 4K Quality: Removed `p.pixelDensity(1)` restrictions. High-end PCs will
now render at full device resolution (Retina/4K) instead of being downscaled.
2. Zoom Sketch Optimization:
- Viewport Culling: Implemented background slicing logic to only render the
visible portion of the static background image, significantly reducing GPU
bandwidth usage during zoom.
3. UX & Animation:
- Camera Smoothing: Applied a frame-rate independent Lerp (factor 0.5) to the
zoom camera. This mimics the weight and feel of the main radar cursor.
- Visual "Lead": Added a `leadFactor` (0.2) to the dashed hover circle. It
now interpolates between the camera and mouse, making controls feel
instant/elastic even while the view smooths out.
- Coordinate Fixes: Updated tooltip and connector logic to map correctly
from the smoothed camera space to screen space.
Addresses performance bottlenecks on high-end PCs and refines the
zoom interaction model to eliminate jitter while maintaining responsiveness.
Performance Optimizations:
1. High-DPI Scaling Fix:
- Forced `p.pixelDensity(1)` in zoomSketch.
- Issue: Retinal/4K screens were defaulting to pixelDensity 2.0+, causing
the GPU to render 4x the necessary pixels (e.g., 1000x1000 for a 500x500 canvas).
This bandwidth saturation caused FPS drops on powerful GPUs.
2. Refresh Rate Uncap:
- Set `p.frameRate(144)` explicitly.
- Issue: p5.js often throttles to 60fps. On 75Hz+ monitors, this caused a
"beat frequency" judder where update cycles missed display refresh cycles.
UX & Animation Logic:
1. Camera Smoothing (The "Cinematic" Feel):
- Decoupled the Zoom Camera position from the Raw Mouse position.
- Applied a Lerp smoothing factor of 0.5 (aligned with main radarSketch
cursor logic) to create fluid motion without feeling sluggish.
2. Visual "Lead" / Elasticity:
- Introduced `zoomLeadFactor` (0.2) for the dashed hover circle.
- The circle position is interpolated between the Smoothed Camera and
the Raw Mouse.
- Benefit: This creates a visual cue that "leads" the camera, making the
controls feel responsive/instant even while the view smoothly catches up.
3. Coordinate System Fixes:
- Reverted manual world-to-screen reprojection for tooltips.
- Adopted a relative screen-space transform:
(ItemScreenPos - CameraPos) * ZoomFactor.
- This ensures connector lines lock perfectly to visual elements regardless
of camera lag.
- Clamp delta time to minimum of 0 to prevent negative interpolation.
- Add protection against division by zero in SNR color mapping.
- Ensure trajectory points exist before fading alpha calculation.
- Standardize p.deltaTime usage for cross-browser stability.
Refactors animation and interpolation logic to ensure consistent behavior
across different monitor refresh rates (e.g., 60Hz vs 144Hz).
Changes:
- Implement time-delta adjusted smoothing for FPS counter and mouse tracking.
- Update IFT graph scaling in 'dom.js' to use performance-based delta time.
- Remove hardcoded 60FPS limit in zoom sketch to allow native refresh rates.
- Fix vertical tooltip jitter in 'drawUtils.js' by using smoothed mouse coordinates.
- Add 'lastOverlayUpdateTime' to global state for cross-module time tracking.
Adds linear interpolation (lerp) to mouse coordinates in the zoom view
to prevent jitter and provide a smoother user experience when inspecting
radar points.
Changes:
- Add `smoothedMouseX` and `smoothedMouseY` state to `radarSketch.js`.
- Apply smoothing factor (0.5) to mouse movement in the main draw loop.
- Update `handleCloseUpDisplay` and zoom sketch drawing to use smoothed coordinates.
- Ensure coordinates snap to mouse position on the first frame to prevent visual jumping.
- Implemented smooth dynamic scaling for the Inter-Frame Timing (IFT) graph that remains active even when playback is paused.
- Added a conditional `requestAnimationFrame` loop to ensure the graph scale converges smoothly to the target value during scrubbing or pause states.
- Tuned animation speeds: fast convergence (0.1 smoothing) during playback, slower (0.033) when paused for a more polished visual transition.
- Fixed a layout thrashing (forced reflow) performance issue in `updatePersistentOverlays` by reading `clientWidth` before writing text updates to the DOM.
radar view (src/drawUtils.js):
- Refactored drawTrackMarkers with a smart collision-resolution algorithm for floating labels.
- Added leader lines and themed tooltips for track IDs and speed data to prevent overlapping.
- Optimized velocity vectors with arrowheads and reduced thickness for better clarity.
- Updated drawRegionsOfInterest to use ROI_CLOSE_Y_MAX constant.
speed graph (src/p5/speedGraphSketch.js):
- Implemented a MATLAB-style spectral color scheme (Blue-Cyan-Green-Yellow-Red) to visualize track density on the CAN speed
line.
- Added a vertical smooth gradient legend bar for track density.
- Switched to robust 95th percentile normalization for density mapping to mitigate outlier noise.
- Synchronized density calculations with the "Confirmed Only" toggle.
- Updated the horizontal legend to reflect density-based coloring.
zoom view (src/p5/zoomSketch.js):
- Adjusted tooltip vertical offset for improved diagonal positioning.
- Disabled internal track detail boxes to prioritize the specialized zoom tooltip system.
- Implement robust fallback and safety logic to prevent division-by-zero or invalid state crashes.
- Update scale calculations and drawing utilities to use dynamic boundaries from appState.
- Refine radar-info-overlay to match plot width and center text content for better alignment.
- Add double-click reset functionality to the range slider to revert to default constants.
- Fix hover detection bug in God Mode during scroll-zoom interactions.
- Ensure Regions of Interest (ROI) scale proportionally with the dynamic plot range.
Vehicle Dimensions:
- Added "Show Dimensions" toggle to the display settings.
- Implemented `drawObjectDimensions` in `drawUtils.js` to render object extents as oriented rectangles based on `objectExtentRadii` and `objectExtentAngle`.
- Updated `radarSketch.js` to draw dimensions when enabled.
- Ensured dimensions and covariance ellipses are drawn at the `correctedPosition` for accurate alignment with track markers.
Track Visualization:
- Updated `drawTrajectories` to prioritize the `risk` property on track logs for coloring (0=Low/Blue, 1=Medium/Orange, 2=High/Red).
- Added fallback to `ttcCategoryTimeline` for backward compatibility.
- Fixed off-by-one error in trajectory history filtering to prevent drawing future points.
Frame Synchronization & UI:
- Refactored frame number display logic across Overlays, Data Explorer, and Timeline.
- UI now displays the actual `frameIdx` from the data source instead of the internal array index, resolving discrepancies between the Data Explorer and the main view.
This commit introduces several improvements to the radar visualization, focusing on responsiveness, error handling, and clearer data representation.
**Key Changes:**
* **Responsive Radar Overlay:** The persistent radar information overlay (`ift-dot-matrix` canvas) in `dom.js` is no longer a fixed size. It now dynamically adjusts its width to match the radar plot's size, ensuring a consistent visual experience across different screen resolutions and resize events. The internal drawing logic has been updated to dynamically calculate column counts based on the canvas's current dimensions.
* **Improved Error Handling in Drawing Utilities:** Comprehensive `try...catch` blocks have been added to all major drawing functions within `drawUtils.js`. This significantly enhances the application's robustness by gracefully handling potential errors during rendering, preventing crashes and providing better debugging insights.
* **TTC Category Fallback:** In `drawUtils.js`, the trajectory drawing logic for Time-to-Collision (TTC) now includes a fallback mechanism. If a track's `ttcCategory` is undefined or invalid, it will default to a neutral gray color, ensuring that trajectories are always rendered with a clear visual state.
- Implemented a "First Run" detection using `sessionStorage`.
- The User Guide modal now appears automatically when application is launched in a new tab or window.
- Logic added to skip the automatic file loading (cached session) on the first run to ensure a clean start for new sessions.
- Subsequent page reloads within the same session will hide the guide and resume the cached session as normal.
Create `shortcuts.html` as a standalone reference page.
Implement `#shortcuts-modal` in `index.html` to display key bindings.
Implement `#guide-modal` with an iframe to embed `User_Manual.html` directly in the app.
Refactor header navigation into color-coded buttons (Green/Blue/Amber-Indigo).
Update `src/dom.js` and `src/ui.js` to handle modal visibili and interactions (ESC key, 'k' key, click-to-close).
Improve visual consistency of header button heights and moda styling.
This commit refactors the monolithic `main.js` file to improve modularity, maintainability, and separation of concerns. The core application logic is now organized into more focused modules.
- **UI Logic (`ui.js`):** All general UI event listeners, including feature toggles, sliders, menu controls, and tooltips, have been moved from `main.js` into a new `src/ui.js` module. This centralizes UI-specific behavior.
- **Session Management (`session.js`):** The functionality for saving and loading application sessions has been extracted into a dedicated `src/session.js` module. This isolates all logic related to session state serialization and file handling.
- **`main.js` Simplification:** The `main.js` file now serves as a cleaner entry point, responsible for initializing all the different application modules in the correct order.
**Bug Fixes during Refactoring:**
- Corrected an issue where activating "God Mode" (`toggleCloseUp`) did not properly start the p5.js `loop()`, preventing the visualization from updating with mouse movement.
- Ensured the `toggleConfirmedOnly` state is now correctly saved and restored as part of the session file.
Adds a 'wheel' event listener to the speed graph container, binding it to the existing `handleTimelineWheel` function.
This change enhances user experience by allowing timeline scrubbing via the mouse scroll wheel when the cursor is over the speed graph. It creates consistent behavior across all major visualization components (radar canvas, timeline, and speed graph), improving the application's usability.
The logic is centralized within `initSyncUIHandlers` in `sync.js` to keep all synchronization-related event bindings in one place.
Improves the time offset feature by making manual offsets persistent and enhancing the user workflow.
- **Persistent Manual Offsets**: Manual offsets are now saved to IndexedDB, keyed by filename. They are automatically applied when the same file is loaded in a future session.
- **Click to Revert & Forget**: The "Manual" status indicator is now clickable. Clicking it reverts to the auto-calculated offset and, crucially, deletes the saved manual offset from the database. This ensures future sessions will correctly default to the automatic calculation.
- **Consistent UI**: The "Manual" indicator now appears instantly with a consistent gray style, whether set manually or loaded from cache, removing UI ambiguity.
- **Refactored Sync Logic**: The `revertToAutoOffset` function has been refactored to reuse the core `forceResyncWithOffset` logic. This reduces code duplication and centralizes the synchronization process, making it more robust and easier to maintain.
Resolve infinite p5.js auto-draw loop during file processing by ensuring comprehensive UI cleanup and correct p5 instance lifecycle management (`redraw` instead of `lo`).
Introduce conditional video retention in `resetUIForNewLoad`, allowing the loaded video to persist when only new JSON data is supplied.
The new loop iterates through the data and draws rectangles directly to the canvas. It changes ctx.fillStyle more often (once per column), but this cost is negligible to the cost of allocating and collecting memory 60 times a second. This should resolve the heap memory issue you observed.

3 - Implemented hover tooltips in `speedGraphSketch.js` to displ
CAN/Ego speeds and timestamps.
4 - Added drag-to-seek (scrubbing) and click-to-seek functionali
using native pointer events for smooth navigation.
5 - Integrated graph seeking with centralized `updateFrame` logi
to ensure consistent video synchronization and UI updates.
6 - Refactored input handling to use DOM listeners on the canvas
resolving conflicts with global p5 events (e.g., play button
issues).
7 - Optimized `theme.js` to redraw only the static graph buffer
theme changes instead of re-processing the entire dataset.
