Architecture & full build

/ INTRO

Local-first desktop tool with a security-hardened, zero-network architecture.

/ STACK

  • Rust
  • Tauri 2
  • cargo-deny
  • CSP isolation
  • golden tests

/ DETAIL

Isolated sidecar design — a zero-dependency Rust core (~6,840 lines) shipped as a separate binary inside a Tauri 2 shell (~112 commits). Hard networking ban enforced end to end: cargo-deny + a CSP with connect-src 'none' + isolation tests. Golden-test and done-rubric process with an append-only decision log.
