🛡️ GhostSlate

Autonomous AST Program Repair, Time-Travel Debugger & Self-Healing Execution Sandbox. Built on Hexagonal Ports & Adapters with Tree-Sitter C grammars, a Two-Tier Multi-Agent Debate Loop (Triage Synthesizer ↔ Adversarial Critic), and an isolated subprocess test runner guaranteeing 100% Green verification before code suggestions are displayed.

✨ Features

🎯 Tree-Sitter AST Scoping & Surgical Node Isolation

No Whole-File Hallucinations: Traditional AI coding tools perform destructive whole-file rewrites that wipe comments, format unrelated blocks, and alter surrounding logic. GhostSlate uses Tree-Sitter C grammars and Python AST to isolate the exact syntax node (IfStatement, MethodBody, Comparison) responsible for the breach.
Enclosing Scope Bounds: Intelligently maps syntax coordinates (start_point to end_point) and preserves surrounding indentations, types, and class structures intact.

⏳ State Invariant Time-Travel Scrubber

Frame-by-Frame Execution Playback: Don't just inspect where an error triggered—scrub backwards and forwards in time to inspect how state mutated into corruption.
Live Variable Delta Inspection: Dynamic variable scope cards show real-time variable mutations at every execution frame.
Invariant Breach Alerting: Automatically traps invalid states (e.g. negative balances, boundary overflows, null pointer dereferences, or ledger imbalances) and highlights the culprit variable, expected invariant condition, and corrupt runtime value.

🤖 Two-Tier Multi-Agent Debate Loop

⚡ Triage Agent (Synthesizer): Analyzes the runtime invariant violation, identifies the faulty AST node, and crafts a minimal reproducible unit test alongside a surgical diff patch.
🛡️ Adversarial Critic (Auditor): Actively red-teams proposed patches against edge cases, boundary conditions, and type invariants (e.g. barring negative transaction inputs or typecasting nullable JSON tokens).
Consensus Gating: The patch only moves to execution when both agents reach cryptographic consensus and issue an audit approval.

🧪 Deterministic Sandbox Runner (Subprocess Isolation)

Zero Demo Flakiness: Runs inside an ephemeral temporary workspace using Python subprocess isolation.
Strict Verification Gate: Code patches are never marked as valid or merged unless internal tests transition from ❌ Red Failed (Exit 1) to ✅ 100% Green Passed (Exit 0).
Microsecond Timing: Sub-second execution benchmarking with cryptographic proof tokens.

📝 Monaco AST-Scoped Diff Studio

High-Fidelity Code Studio: Embedded Monaco Diff Editor with side-by-side and inline visual diff toggles.
Unified Diff Metrics: Real-time calculation of inserted, modified, and deleted lines, proving minimal change radius.
1-Click Copy: Instant clipboard export for git patches and unified diffs.

💥 Interactive Chaos Injection Simulator & Custom Sandbox

One-Click Bug Scenarios & Live Code Studio: Pre-configured with 6 realistic scenarios including arbitrary user code execution:
1. Concurrent Order Book Race Condition (Double-spending & negative balances)
2. Sliding Window Rate Limiter Off-By-One (len(timestamps) <= max_requests boundary bug)
3. JWT Auth Context Null Pointer (NoneType member dereference)
4. Double-Entry Financial Ledger Imbalance (Solvency conservation failure)
5. High-Priority Stream Interrupt & Causal Watermark (Monotonic sequence reordering)
6. Custom Evaluator Sandbox (Interactive source code & pytest assertion studio with live dynamic AST repair)
5-Stage Visual Stepper: Watch the healing pipeline progress live through Invariant Breach → AST Isolation → Agent Debate → Subprocess Pytest → 100% Green Verified.
Hands-Free Keyboard Shortcuts: Rapid-fire hotkeys (1-6 scenario select, Space trigger heal, E export PR, ? shortcuts cheat sheet, Esc dismiss).

📦 1-Click Pull Request & SARIF Compliance Exporter

Production-Ready PRs: Generates formatted markdown Pull Request descriptions with root cause summaries, unified diffs, and deterministic sandbox proofs.
SARIF v2.1.0 Export: Direct export in Static Analysis Results Interchange Format for GitHub Security Code Scanning and CI/CD pipelines.

💬 Challenge Card #2: Real-World Feedback & Community Iteration

Full Documentation & Visual Proofs: See the /feedback directory for conversation logs, community critique, and verified screenshots.
Public Outreach: Shared on LinkedIn (https://lnkd.in/p/ddR6nADX) tagging @GREVIX.

GhostSlate was shared directly with peer developers, students, and backend engineers to gather unfiltered critique on how developers would use autonomous program repair in production.

Contributor / Peer	Community Role	What People Told Us	What We Changed Because Of It	Status
Aarav S.	Systems Engineer	"The canned scenarios are great, but evaluators need to test their own code. Can I paste my own broken Python class and custom pytest assertion to see it self-heal live?"	Built Interactive Custom Evaluator Sandbox: Added live code and test textareas with presets (Buffer Overflow, Token Bucket, Vault Solvency) and dynamic AST boundary repair.	🟢 Merged
Priya K.	Full-Stack Developer	"Switching scenarios and triggering heals with a mouse slows down live presentations. Can you add keyboard shortcuts?"	Engineered Hands-Free Hotkeys: Added global hotkeys for `1`-`6` (scenario switch), `Space` (run heal), `E` (PR export), `?` (shortcuts cheat sheet), and `Esc`.	🟢 Merged
Dev M.	Distributed Systems Student	"For the out-of-order interrupt scenario, how can I be sure the re-sequencing actually happened under 15µs latency rather than being pre-computed?"	Live Stream Sync Telemetry Banner: Integrated real-time jitter distance (frames), reordered frames count, causal watermark latency (µs), and monotonic integrity proofs into the UI.	🟢 Merged

🚀 Getting Started

1. Backend Setup

# Clone the repository
git clone https://github.com/saad2134/GhostSlate.git
cd GhostSlate

# Install Python dependencies
pip install fastapi uvicorn pydantic pytest tree-sitter tree-sitter-python tree-sitter-javascript

# Start the FastAPI engine (port 8000)
python -m uvicorn backend.main:app --host 127.0.0.1 --port 8000

2. Frontend Studio Setup

# In a new terminal, navigate to frontend
cd frontend

# Install dependencies
npm install

# Start the Vite development studio (port 5173)
npm run dev

Open your browser at http://127.0.0.1:5173 to launch GhostSlate.

3. Headless CLI Execution (CI/CD Mode)

You can run GhostSlate directly in headless CI/CD pipelines without opening the web interface:

# Run automated repair for a scenario and export a SARIF audit report
python -m backend.adapters.presentation.cli_adapter --scenario race_condition --output-sarif audit.sarif

🔒 Security & Data Integrity

GhostSlate enforces strict defense-in-depth isolation across all program repair pipelines and sandbox execution environments:

Isolated Ephemeral Subprocess Sandboxes: Every candidate patch is tested in an ephemeral temporary directory generated with tempfile.TemporaryDirectory(). The test workspace is destroyed immediately after execution.
Sanitized Execution Environment (clean_env): Subprocesses run with a stripped environment dictionary that purges all parent process secrets, tokens, API keys, and sensitive environment variables (os.environ).
Subprocess Resource Quotas & Timeouts: Sandbox runs enforce a strict 5.0-second execution deadline (timeout=5.0). Infinite loops or hangs are forcefully terminated with SIGKILL / terminate(), preventing Denial of Service.
Arbitrary Code Execution Hardening: The sandbox runner inspects source strings for prohibited modules (os.system, subprocess.Popen, arbitrary sockets) prior to dispatch.
Cryptographic Diff Line Boundaries: Tree-Sitter AST parser enforces surgical coordinate boundaries, ensuring zero unauthorized mutations outside the enclosing target scope.

♿ Accessibility (WCAG AA Compliance)

GhostSlate is built to comply with WCAG 2.1 AA accessibility guidelines across all interaction vectors:

Keyboard Navigation & Global Hotkeys:

Shortcut	Action	Description
`1` ✦ `6`	Scenario Switch	Instant toggle across 6 chaos scenarios
`Space`	Trigger Heal	Dispatches live chaos injection & automated AST self-healing loop
`E`	Export Modal	Opens 1-Click GitHub PR markdown & SARIF v2.1.0 exporter
`?` or `/`	Hotkey Cheat Sheet	Toggles interactive keyboard shortcuts modal
`Esc`	Dismiss Overlays	Closes any open modal or active dialog

Skip to Content Landmark: Features a top-level <a href="#main-content" class="skip-to-content"> allowing screen reader and keyboard-only users to bypass navigation straight to the interactive sandbox.
Semantic HTML5 Landmarks: Built using <header>, <main id="main-content">, <nav>, and <footer> with explicit aria-label tags on all interactive buttons and icons.
Touch Targets & Contrast: All interactive controls maintain minimum 44px touch envelopes with high-contrast text ratios exceeding WCAG AA standards (4.5:1 for body copy, 7:1 for headers).

🎨 Design Philosophy & Aesthetics

GhostSlate adheres to a strict Vercel High-Contrast Monochrome visual design system:

Pitch-Black Core Canvas: #000000 pitch black background paired with elevated #0a0a0a card backdrops and hairline #222222 (var(--border-subtle)) borders.
Functional State Accents:
- Emerald (#10b981): 100% Green Verified test passes and causal stream sync active state.
- Crimson (#ef4444): Invariant breaches, failed tests, and AST deletion diff lines.
- Amber (#f59e0b): Isolated AST target nodes, jitter warnings, and candidate repair warnings.
- Sky (#38bdf8): Subprocess execution and temporary workspace orchestration.
Non-Blocking Fluid Typography: Uses Geist, JetBrains Mono, and Inter loaded asynchronously via non-blocking media queries for optimal First Contentful Paint (FCP).
Aceternity UI Micro-Interactions: Subtle spotlight borders (SpotlightCard), fluid decrypted text reveals (DecryptedText), count-up counters, and animated shimmer action buttons (ShimmerButton).

🧪 Test Suite & Verification

All automated tests in GhostSlate are deterministic and run offline with zero cloud dependency.
