### Milestone Overview

The Phase 1 MVP of CyberSim-OS establishes a browser-native, zero-dependency simulation environment designed to assess end-user cybersecurity behavior in a realistic workplace context.

### Key Deliverables Implemented

1. **Fictional Desktop Shell & Window Manager**:
   - Original enterprise Windows-like theme with draggable and minimizable window frames, taskbar, start launcher, real-time clock, and Web Audio synthesized toast alerts.

2. **Core Workplace Application Suite**:
   - **Inlook**: Email client with RFC envelope inspector (detects typosquatted sender domains), destination link hover inspection, and SOC incident reporting.
   - **Navigator**: Simulated web browser supporting intranet directories, security policy hubs, and simulated credential-harvesting phishing portals.
   - **Files & Doc Viewer**: Virtual corporate storage and multi-format renderer for financial spreadsheets (`.xlsx`), security policies (`.pdf`), and approved vendor lists.
   - **Security Center**: Endpoint threat monitoring dashboard, alert feeds, and incident tracking.

3. **Behavioral Telemetry & Delayed Consequence Engine**:
   - Granular event logging recording all learner interactions with timestamps and context.
   - Delayed consequence scheduler that triggers realistic delayed alerts (e.g. anomalous login notifications following credential submissions) without arcade-like immediate feedback.

4. **7-Axis Behavioral Assessment & After-Action Report**:
   - Comprehensive scoring rubric measuring *Threat Detection*, *Investigation*, *Safe Handling*, *Verification*, *Incident Reporting*, and *False Positive Control* on a 0–100 scale (80 passing threshold).
   - Pedagogical debrief modal providing score breakdowns and constructive feedback.

5. **Cryptographic Certificate Verification**:
   - SHA-256 scenario fingerprinting using the native Web Crypto API.
   - Portable `*.cybercert` JSON credential export and standalone drag-and-drop offline verifier (`verify.html`).

6. **Standalone Offline Deployment**:
   - Bundled Python 3 local server launcher (`launcher.py`) binding strictly to `127.0.0.1`.
