📖 Project Description *

Horizon is an Autonomous Enterprise Infrastructure Recovery Platform engineered to safeguard distributed cloud architectures against catastrophic system outages, cascading microservice dependency crashes, and uncoordinated disaster recovery operations.

Modern enterprise applications comprise complex webs of polyglot databases, distributed caches, event-streaming message brokers, authentication clusters, internal gRPC services, and edge API gateways. When critical stateful nodes fail, manual recovery in high-pressure emergency "War Rooms" frequently results in out-of-order service restarts, triggering thundering herds, database connection pool starvation, and multi-hour cascading outages.

Horizon resolves this fundamental engineering challenge by providing a fully automated, mathematically governed resilience and disaster recovery engine:

Continuous Telemetry & Anti-Flapping Surveillance: Observes distributed nodes in real time through Datadog/Dynatrace APM probes and synthetic heartbeats, employing a 3-consecutive-miss sliding window to eliminate transient network jitter false positives.
Deterministic Dependency Graph Resolution: Constructs a live Directed Acyclic Graph (DAG) of the entire infrastructure and computes mathematically sound, deadlock-free bottom-up recovery sequences using Kahn's Topological Sorting algorithm $\mathcal{O}(V+E)$ paired with Tarjan's Strongly Connected Components analysis.
Dual-Path Risk-Tiered Governance: Safely automates low-risk operational remediation (cache purges, queue drains, container restarts) with sub-second execution while halting high-impact state mutations (database primary failover, point-in-time storage restoration, cross-region DNS cutover) behind a cryptographic EIP-712 Human-in-the-Loop Web3 Approval Gate.
Sovereign Multi-Agent SRE Reasoning: Leverages Sarvam AI (sarvam-2b and sarvam-105b) to synthesize root-cause diagnostics and generate declarative Kubernetes/Docker manifests, protected by an Indic multilingual safety barrier.
Decentralized Trust on MST Blockchain: Enforces non-repudiable Incident Commander authorization via BridgeKey Web3 Wallets, anchors 32-byte Merkle root audit proofs into an on-chain ledger (HorizonAuditVault.sol), and gates enterprise platform access through ERC-721 subscription passes (HorizonSubscriptionNFT.sol / ZXPASS) on the MST Blockchain Testnet (Chain ID 91562037).
Universal Agent Interoperability via MCP: Ships a production-grade 12-tool Model Context Protocol server, enabling AI assistants (Claude Desktop, Cursor IDE, Google Antigravity) to inspect cluster topologies, diagnose incidents, execute recovery playbooks, and verify on-chain audit proofs seamlessly.

⚠️ Problem Statement *

In large-scale enterprise production environments (AWS, GCP, Azure, and hybrid on-premise Kubernetes clusters), infrastructure degradation is inevitable. However, legacy disaster recovery methodologies fail catastrophically in four critical dimensions:

└────────────────────────────────────────────────────────────────────────────────────────────────────────┘

1. The Cascading Dependency Trap & Out-of-Order Chaos

Distributed systems have strict structural dependencies: an API Gateway depends on Auth Services, which depend on Redis Caches and PostgreSQL Primary Datastores. During major outages, panicking SREs frequently restart edge services before backend datastores are read-ready. This triggers thundering herd storms, instantaneous socket pool exhaustion, and cascading crash loops that amplify the initial failure across the entire service mesh.

2. Alert Flapping & On-Call Fatigue

Transient packet loss, momentary GC pauses, and brief network jitter frequently cause single-ping telemetry drops. Legacy monitoring platforms trigger instantaneous P1 alarms, waking SREs at 3:00 AM for false alarms. Over time, alert fatigue leads teams to ignore or delay response to legitimate catastrophic failures.

3. The Autonomy Paradox: Runaway Scripts vs. War Room Bottlenecks

Enterprise engineering leadership faces a paralyzing dilemma:

Unchecked Automation: Fully autonomous remediation scripts lack situational safety boundaries. A runaway script executing an unverified primary database failover can cause permanent data loss, split-brain replication divergences, and corrupted transaction logs.
Manual War Rooms: Requiring human consensus for every trivial action bogs teams down in frantic Slack channels and Zoom calls. The average enterprise Mean Time to Recovery (MTTR) stretches to 45–60+ minutes, costing Fortune 500 enterprises an average of $9,000 to $14,000 per minute of downtime.

4. Regulatory Audit Vulnerabilities & Forensic Non-Repudiation

Post-incident forensic investigations are frequently compromised by mutable, centralized log storage. Database administrators or compromised credentials can alter, truncate, or delete server logs to conceal negligence or compliance breaches. Furthermore, emerging statutory directives—such as CERT-In's mandatory 6-hour cyber incident reporting mandate, DPDP Act 2023, and SOC 2 Type II controls—require mathematically verifiable, time-locked, non-repudiable evidence of the root cause, approved playbooks, and authorized personnel.

⚡ Key Features Implemented *

1. The 7-Stage Cryptographic Autonomous Remediation Pipeline

Horizon structures resilience into seven deterministic, verifiable lifecycle stages. Every single stage generates a deterministic SHA-256 cryptographic checksum (0x...), logged to the browser console and aggregated into an on-chain Merkle root digest:

Stage 1/7: APM Telemetry Ingestion & Probe Validation
Stage 2/7: Anomaly Detection & Anti-Flapping P1 Tripwire
Stage 3/7: Kahn's DAG Dependency Sequencing $\mathcal{O}(V+E)$ & Blast Radius
Stage 4/7: Real AI SRE Root Cause Diagnosis (Sarvam AI)

Stage 7/7: On-Chain Merkle Audit Vault Anchoring & Auto-Resolution

2. Kahn's Algorithm Topological Dependency Engine

Implemented in apps/web/src/engine/dependencyGraph.ts and mcpserver/app/engine/topology.py.
Evaluates the live infrastructure dependency matrix as a Directed Acyclic Graph (DAG) in linear time $\mathcal{O}(V + E)$.
Automatically computes in-degree node weights, detects circular deadlocks via Tarjan's Strongly Connected Components algorithm, and segments recovery into discrete, parallelizable bottom-up execution tiers (Tier 0: Datastores $\to$ Tier 1: Caches & Queues $\to$ Tier 2: Internal Services $\to$ Tier 3: Edge Ingress).

3. Anti-Flapping Sliding Window Failure Detection

Implemented in apps/web/src/engine/watchdog.ts.
Evaluates continuous multi-protocol health probes (HTTP GET, TCP handshake, synthetic pings).
Enforces a strict 3-consecutive-miss threshold over a 5-second sliding window before escalating to a critical P1 incident, completely preventing alert flapping from transient network micro-bursts.

4. Sovereign Sarvam AI SRE Copilot & Multi-Lingual Safety Barrier

Implemented in apps/web/src/engine/sarvamAgent.ts and mcpserver/app/engine/sarvam.py.
Dual-Mode Provenance Architecture:
- Mode 1 (Cloud LLM): Real-time integration with Sarvam AI API (sarvam-2b and sarvam-105b-conversations), displaying a green ORIGINAL SARVAM AI CLOUD (HTTP 200) provenance badge and latency telemetry.
- Mode 2 (Deterministic Guardrail): Local heuristic SRE fallback ensuring deterministic responses during connectivity interruptions.
Canonical Safety Barrier: Operators interact in English, Hindi, Hinglish, Tamil, Marathi, Spanish, or French, but all synthesized recovery commands are strictly typed, schema-validated, hash-locked standard English.

5. Web3 EIP-712 Cryptographic Approval Gate

Implemented in apps/web/src/engine/mstBlockchain.ts.
Automatically categorizes playbook steps by risk: Low-risk tasks execute autonomously; High-risk tasks (database promotion, disk rollback) freeze execution.
Dispatches an EIP-712 typed structured data signing prompt to the Incident Commander's BridgeKey wallet, verifying commander authorization on the MST Blockchain before unblocking execution.

6. Immutable Merkle Audit Vault

Implemented in contracts/HorizonAuditVault.sol and apps/web/src/pages/AuditPage.tsx.
Aggregates the deterministic SHA-256 hashes of all 7 remediation stages into a single 32-byte Merkle root.
Anchors the transaction into the deployed smart contract on MST Testnet, providing tamper-proof verification accessible via MSTScan Block Explorer.

7. Model Context Protocol (MCP) Server (12 Enterprise Tools)

Implemented in mcpserver/ and live on Render.
Exposes 12 comprehensive SRE tools over Server-Sent Events (SSE), Direct HTTP JSON-RPC, and Standard I/O (Stdio) for Cursor IDE, Claude Desktop, and autonomous agents.
Includes Datadog/Prometheus webhook ingestion at POST /api/v1/incidents/webhook.

8. Web3 ERC-721 Token-Gated Platform Subscriptions (`ZXPASS`)

Implemented in contracts/HorizonSubscriptionNFT.sol and apps/web/src/pages/SubscriptionPage.tsx.

1. Injected Provider Detection & Resilient Connection Lifecycle

Implemented in apps/web/src/engine/mstBlockchain.ts:

Seamlessly interfaces with BridgeKey Wallet and standard EIP-1193 injected providers (window.ethereum).
Includes resilient delayed-injection detection handling for macOS browsers (Safari extension companion, Brave Shields, Arc) with dynamic eip6963:announceProvider event listeners.
Automatically handles network switching to MST Testnet (Chain ID 91562037) using wallet_switchEthereumChain and automatic fallback chain registration via wallet_addEthereumChain.

2. EIP-712 Typed Structured Data Signing for High-Risk Gates

When a destructive playbook step is triggered (e.g., PostgreSQL Standby Promotion or Point-in-Time Volume Rollback):

Horizon constructs an EIP-712 structured data message containing:
- incidentId: Unique incident tracking hash.
- stepTitle: Human-readable remediation action.
- targetService: Exact infrastructure node being mutated.
- commanderAddress: Public wallet address of the authorizing Incident Commander.
- timestamp: Unix epoch milliseconds.
- chainId: 91562037 (MST Blockchain Testnet).
The Incident Commander cryptographically signs this payload with their private key via BridgeKey Wallet.
The platform verifies the ECDSA signature against the authorized commander registry (AUTHORIZED_WALLETS_LIST), preventing replay attacks and man-in-the-middle exploits.

3. Immutable On-Chain Merkle Audit Vault (`HorizonAuditVault.sol`)

Deployed at 0x8192305827361a29384756281938472619284756 on MST Testnet.
Upon successful execution of all recovery tiers, Horizon hashes the collective SHA-256 checksums from Stages 1 through 6 into a single 32-byte Merkle root digest: $$\text{Merkle Root} = \mathcal{H}\Big(\mathcal{H}(S_1 \mathbin{\Vert} S_2) \mathbin{\Vert} \mathcal{H}(S_3 \mathbin{\Vert} S_4) \mathbin{\Vert} \mathcal{H}(S_5 \mathbin{\Vert} S_6)\Big)$$

Calls the smart contract method:

function recordAuditHash(bytes32 logHash, string memory incidentId, string memory actionType) external onlyOwner;

Any auditor or regulator can verify the authenticity of an incident remediation using the public view method:

function verifyAuditHash(bytes32 logHash) external view returns (bool exists, string memory incidentId, string memory actionType, uint256 timestamp);

4. Decentralized ERC-721 Subscription Engine (`HorizonSubscriptionNFT.sol`)

Deployed at 0x3EDad230dCFc6Dd3C357490b9feDa49639646BB7 under the symbol ZXPASS (HZN-SUB).
Governs decentralized access control across 4 subscription tiers:
- Tier 1 (Explorer): 5.0 MST | AutoLogging Rate Limit: 5 events/min | Up to 10 monitored nodes.
- Tier 2 (Guardian): 15.0 MST | AutoLogging Rate Limit: 10 events/min | Up to 50 monitored nodes.
- Tier 3 (Sentinel): 25.0 MST | AutoLogging Rate Limit: 15 events/min | Up to 200 monitored nodes.
- Tier 4 (Enterprise): 50.0 MST | AutoLogging Rate Limit: 20 events/min | Unlimited nodes & Sarvam AI.
Implements mintSubscription(Tier) and renewSubscription() with 30-day on-chain expirations.
Features getAutoLoggingRateLimit(address user) which allows the backend and client state engines to query on-chain subscription status to enforce telemetry quotas.
Automatically triggers EIP-747 (wallet_watchAsset) upon minting to import the NFT pass directly into the user's wallet with official branding and Cobalt Blue (#0047AB) palette styling.

🛡️ The 7-Stage Cryptographic Pipeline & Checksum Manifest

Horizon eliminates black-box ambiguity by computing a deterministic SHA-256 cryptographic checksum for every stage of remediation. The hashes are verified across the client console and anchored to the MST Blockchain:

Stage	Pipeline Name	Cryptographic Payload	Origin Source	Audit Purpose
1/7	Telemetry Ingestion & APM Probe	Target node ID, latency ($ms$), error rate, consecutive miss count	`telemetry-apm`	Proves incoming probe telemetry integrity
2/7	Anomaly Detection & P1 Tripwire	Incident ID, severity, APM source, computed BFS blast radius	`telemetry-apm`	Proves threshold exceeded and alert triggered
3/7	Kahn DAG Topological Sequencing	Acyclic dependency tiers, directed edges, sequence order	`kahn-dag`	Validates acyclic recovery math $\mathcal{O}(V+E)$
4/7	Real AI SRE Root Cause Diagnosis	Model identifier, prompt string, raw reasoning text, root cause	`sarvam-cloud-llm` / `sre-heuristic-guardrail`	Distinguishes cloud AI vs local guardrail
5/7	EIP-712 Cryptographic Approval Gate	MST Chain ID (`91562037`), Contract, Signer wallet, ECDSA signature	`eip712-gate`	Guarantees non-repudiable human authorization
6/7	Autonomous Playbook Execution	Restored nodes list, completion timestamp, elapsed RTO seconds	`system`	Validates container & service restoration
7/7	Merkle Audit Root Proof Anchoring	Aggregated upstream hashes ($1 \to 6$) hashed into Merkle root	`system`	Anchors immutable verification digest on MST Chain

🎬 Live Hackathon Demonstration Playbook

Follow this 60-second walkthrough to demonstrate the full power of Horizon to evaluators:

Launch the Observability Hub:
- Open http://localhost:5173/observability (or click Platform $\to$ Live Observability).
Demonstrate Anti-Flapping Protection:
- Highlight the 3-Miss Sliding Window indicator. Point out that isolated transient dropped packets do not flap alarms; 3 consecutive failures are mathematically required.
Simulate a Critical Outage:
- Select PostgreSQL Primary (db-primary) and click "Simulate Breach".
- Watch the Datadog APM latency wave surge to 999ms, CPU spike to 96%, and the PagerDuty P1 audio chime sound.
Trigger Autonomous AI Remediation:
- Click "Auto-Remediate with Real AI".
- Observe the Sentinel isolate the BFS blast radius, compute Kahn's topological tiers, ingest Sarvam AI diagnostics (HTTP 200), prompt the EIP-712 approval gate on MST Testnet, and sequentially heal services bottom-up.
Verify Cryptographic Checksums & On-Chain Audit Proof:
- Inspect the 7-Pipeline Checksums Table. Click "Copy Checksum Manifest" to prove end-to-end cryptographic integrity.
- Navigate to /audit to view the 32-byte Merkle root recorded on the MST Blockchain.
