Architecture, Tech Stack & Roadmap
The complete technical blueprint for SIAR: zero single points of failure, multi-region sovereign storage, browser WASM simulation, and 100% verified supply-chain provenance.
Definitive Platform Technology Stack
Engineered for zero-dependency longevity, high performance, and air-gapped survivability.
Core Frontend & UI
Vanilla CSS Design Tokens, HTML5 WebGL / 2D Canvas physics, zero-runtime overhead, and OLED pure-black themes.
Rust & WASM Engine
Pure-Rust protocol framing (`siar-protocol`, `siar-crypto-mls`), WebWorkers, and Postcard binary wire encoding.
Supply Chain Security
Minisign Ed25519 signatures, Sigstore keyless attestation, and SLSA Level 3+ in-toto provenance ledgers.
Edge Compute & CDN
Cloudflare Edge Workers, Anycast DNS, MinIO sovereign bare-metal clusters, and Backblaze B2 WORM storage.
Native Repositories
Official APT (`InRelease`), RPM (`repomd.xml`), F-Droid (`index-v2.json`), Arch PKGBUILD, Homebrew, and Winget.
P2P & Offline Survival
BitTorrent swarms with permanent web seeds, Iroh P2P blobs, and Wi-Fi captive portal emergency repeaters.
Implementation Milestones & Verification
All 4 engineering phases have been completed and verified across the codebase:
Content Security Policy (CSP) & Header Compliance Auditor
Inspect the zero-trust HTTP headers and script isolation policies active across the domain.
Infrastructure Sizing & Bandwidth Capacity Calculator
Estimate monthly origin bandwidth, Cloudflare R2 egress cost ($0.00), and BitTorrent P2P offloading ratio for disaster mesh deployments.
