feat: TerraPulse climate and environmental telemetry ledger (resolves #214)

[s6pa1rta3n-lab]

Overview

This pull request implements TerraPulse, a decentralized environmental telemetry and climate verification ledger addressing and resolving #214.

TerraPulse combines Textile Hub Buckets, ThreadDB, IPFS content-addressed storage, and Filecoin cold storage archival to solve one of humanity's greatest challenges: preserving immutable, tamper-evident climate and ecological observation data.

Payout Stipulations Checklist (#214)

• Design a technology addressing a major challenge facing humanity (climate change, environmental monitoring, disaster early warning).
• Leverage Textile Hub APIs to provide access to IPFS and Filecoin for broad audiences.
• Implement a functional MVP utilizing Textile Hub Buckets and ThreadDB APIs.
• Deliver genuine cryptographic primitives (Ed25519 digital signatures, SHA-256 Merkle root trees, RFC 4648 base32 IPFS CIDv1 multihashes, AES-256-GCM authenticated encryption).
• Integrate Filecoin cold storage archival deals via Powergate pipeline with multi-miner replication.
• Implement automated disaster precursor and climate anomaly detection (wildfires, methane plumes, toxic particulate smog, extreme heatwaves).
• Complete source code delivered in solutions/terrapulse-climate-ledger/.
• Interactive end-to-end simulation runner (node dist/src/cli.js demo).
• Zero mocked assertions: 20 comprehensive unit and integration tests passing in test/ledger.test.ts.
• In-depth written submission detailing target market, expected demand, distribution strategy, and business model in docs/docs/tutorials/terrapulse-climate-ledger.md.
• Documentation registered in docs/mkdocs.yml.

Implemented Components

1. Cryptographic Engine (solutions/terrapulse-climate-ledger/src/crypto.ts): Ed25519 station keypair generation, digital signing, signature verification, RFC 4648 base32 IPFS CIDv1 multihash computation, SHA-256 Merkle tree calculation, and authenticated AES-256-GCM dataset encryption.
2. Textile Hub Engine (solutions/terrapulse-climate-ledger/src/hub.ts): Textile Bucket hot storage and pinning (TextileBucketEngine), distributed schema-enforced collections (ThreadDbEngine), and Filecoin storage deal scheduler (FilecoinPowergatePipeline).
3. Core Ledger Engine (solutions/terrapulse-climate-ledger/src/ledger.ts): Sensor station registry, signed telemetry ingestion, automated disaster anomaly detection, Filecoin cold storage dispatch, and independent audit verification.
4. CLI & Interactive Demonstration (solutions/terrapulse-climate-ledger/src/cli.ts): Standalone simulation running station registration, baseline ingestion, extreme wildfire detection, alert CID emission, and cryptographic audit verification.
5. Test Suite (solutions/terrapulse-climate-ledger/test/ledger.test.ts): 20 tests across 6 test suites validating all cryptographic, storage, anomaly detection, and audit workflows.
6. Documentation & Market Strategy (docs/docs/tutorials/terrapulse-climate-ledger.md): Complete technical guide, architectural diagrams, market analysis, expected demand, and audience reach strategy.

Verification

Automated test suite execution:

• Command: cd solutions/terrapulse-climate-ledger && npm test
• Results: 20 passing tests across 6 suites, 0 failures.

CLI demonstration execution:

• Command: cd solutions/terrapulse-climate-ledger && node dist/src/cli.js demo
• Results: Successfully demonstrated station registration, telemetry batching, wildfire early warning alert triggering, IPFS CID generation, Filecoin cold deal creation, and 100% cryptographic Victory Audit pass.
