Legacy Browser Compatibility Suite & Diagnostics Hardening

Comprehensive architecture overhaul ensuring full functional and visual compatibility across legacy browser engines (Google Chrome 50–55 on Windows 7, Safari 8–10 on macOS), centralized stylesheet architecture, and enhanced hardware scanner session synchronization.

Legacy Engine Layout Hardening
  • LAYOUT Numpad Flexbox Architecture: Replaced modern CSS Grid with a resilient dual-column Flexbox layout (.numpad-container) using pure margins, resolving the Chrome < 57 vertical collapse bug while preserving spanning keys.
  • LAYOUT Universal Sibling Margins: Replaced unsupported flexbox gap properties with adjacent sibling margin rules (.speaker-box + .speaker-box) to ensure proper 80px physical separation on Chrome < 84 without gap doubling.
  • ALIGN Keyboard Alignment Standardization: Standardized main keyboard section to 639px with proportional flex-grow spacing, aligning function keys, spacebar, and right-hand modifier keys flush with the perimeter.
  • CSS CSS Centralization: Consolidated all component and test styling into central css/style.css with timestamped cache busters (?v=...) to prevent edge proxy cache collisions.
Diagnostic Runtimes & Scanner Polling
  • CORE Pre-Populated Scanner Sessions: Session IDs are now generated directly on the server in PHP and pre-rendered into PowerShell, macOS, and Linux scanner commands on first paint, guaranteeing session presence without client-side JS dependency.
  • FIX Pure ES5 URL Parameter Parser: Replaced modern URLSearchParams with a pure ES5 query parser, preventing fatal script crashes on Chrome 50 and ensuring background scan polling begins immediately on page load.
  • AUDIO Legacy Media & Web Audio Fallbacks: Added 3D PannerNode equalpower fallback for audio panning in speaker tests, along with WebKit legacy stream bindings (webkitGetUserMedia / URL.createObjectURL) and fallback container heights for webcams.
  • NAV Vanilla Dropdown Controller: Built an independent fallback controller in js/legacy-compat.js for navigation dropdowns and mobile toggles when third-party bundles are unreachable.

Device Information UI Overhaul & Hardware Detection Refinements

Introduced a deeply refined, collapsible master card for Device Information alongside scanner patches for accurate RAM clock speeds.

Dashboard UI Upgrade
  • UI Redesigned the Device Information section into a clean, collapsible master accordion.
  • GRID Implemented a balanced 3x2 quick-glance system summary grid on the collapsed card face.
  • DISK Added intelligent storage array aggregation (caps at 2 drives with a +More indicator) for clean UI scaling.
  • MAC Added dynamic Apple device field masking (hiding SKU/UUID for native Macs).
Core Scanner & Fixes
  • METRIC Added missing hardware data metrics: CPU Core Counts, system Chassis Type, and individual RAM Serial Numbers.
  • RAM Patched Windows PowerShell RAM scanner to accurately detect high-speed LPDDR4x/LPDDR5 memory frequencies via ConfiguredClockSpeed.
  • CPU Refined dynamic CPU string parsing for dual-processor configurations.
  • NAV Resolved an issue where the "All Tests" button in the navigation header was unresponsive.

Storage Telemetry macOS Native REST API Portal UI & UX
August 26, 2026

Storage Telemetry, Client API Portal, Native macOS Scanner & Barcode UI

A major consolidated system release introducing native macOS disk telemetry, client-side B2B REST API management, commercial capacity rounding, operational Power-On Time, and responsive barcode UI scaling.

Storage Telemetry & macOS Native
  • DISK Native macOS disk health monitoring & lifetime read/write volume tracking (TBW).
  • TIME Operational Power-On Time formatting and power cycle telemetry.
  • SPEC Commercial drive capacity tier rounding (e.g. 1,024 GB displayed accurately as 1 TB).
  • SMART Apple Regulatory Model number identification, TRIM verification, and S.M.A.R.T. health status.
B2B REST API & UI Enhancements
  • API Secure Client REST API Portal with instant key generation and live integration examples.
  • QUERY Public REST API endpoints supporting programmatic scan lookup by Test ID or Serial Number.
  • SCAN Responsive barcode scanning modal with auto-scaling dimensions and boundary constraints.
  • UI Formatted Test ID display with unspaced clipboard copying.
