Phase 2.5: Runtime Localization, Corporate Branding, and Immersive Login

Milestone Overview

CyberSim Phase 2.5 prepares the simulation platform for organizational deployment and Phase 3 scenario authoring. This milestone introduces a robust localization layer, configuration-driven enterprise branding, an immersive workstation login experience, learner first- and last-name personalization, standalone certificate rendering and printing, and cross-locale offline credential verification while preserving 100% offline execution and strict security boundaries.

Key Deliverables Implemented

1. CyberSim OS & Scenario Multilingual Localization (I18n):

   • Built a standalone, offline-first localization engine (i18n.js) with deterministic fallback behavior (Selected Locale -> Deployment Default Locale -> English -> visible [missing: key] indicators).
   • Embedded full English UI catalogs (locales/en.json) and Spanish demonstration catalogs (locales/es.json) for instant offline dictionary availability.
   • Decoupled scenario content localization (scenarios/[id]/locales/[lang].json), enabling independent translations of emails, documents, web pages, notifications, and pedagogical feedback without altering scenario schemas or scoring logic.

2. Deployment Configuration & Corporate Branding:

   • Implemented src/config/deployment.json and a dynamic BrandingManager (branding.js) to customize organization identity (name, short name, logo, wallpaper, accent color, and service desk contact) via CSS custom property injection.
   • Built automatic fallbacks to default CyberSim enterprise styling when custom branding properties are omitted.
   • Preserved simulation safety indicators to maintain clear simulation boundaries.

3. Immersive Workstation Login & Dynamic Network Discovery:

   • Replaced raw scenario loading with an enterprise lockscreen interface (login.js) featuring real-time language switching, strict first- and last-name input validation (required, trimmed, max length 50), and dynamic workplace network selection.
   • Added direct verification shortcut links on the login screen to allow verifying completion certificates without logging into a simulation.
   • Avoided any credential or password entry requirements on the simulated OS login screen.
   • Extended scenario manifest schemas to support supportedLocales declarations and login metadata (networkName, networkDescription, networkIcon).

4. Learner Full-Name Personalization & Security Boundaries:

   • Exposed learner.firstName, learner.lastName, and full learner.name to scenario action dispatchers, simulated workplace applications, and certificate generators.
   • Implemented safe template interpolation with HTML entity escaping to prevent cross-site scripting (XSS) or HTML injection from user-provided names.

5. Deterministic Cryptographic Verification & Print Rendering:

   • Canonicalized SHA-256 fingerprinting (fingerprint.js) against the base scenario structure, ensuring that completion certificates issued in one language remain 100% machine-verifiable in any language.
   • Updated the standalone offline certificate verifier (verify.html) to render the full official Certificate of Competency upon successful validation, with dedicated print styling and export actions.

6. Comprehensive Automated Verification & Zero External Dependencies:

   • Added an automated Node.js test suite (tests/run_tests.js) covering localization fallback, branding defaults, login validation, template escaping, cross-locale fingerprinting, and offline dependency verification.
   • Verified 100% offline compatibility with zero external CDN, font, or API requirements.
