TPT Cortex

Give PWAs native superpowers — without the app store.

TPT Cortex is a custom statically-typed DSL and lightweight VM that lets web apps declare background tasks, hardware interactions, and local data operations executed by a native companion process. No WebView jail. No Play Store. No iOS App Store.

Architecture

PWA (Svelte)  <──WebSocket──>  cortex-daemon (Go)  <──FFI──>  cortex-engine (Rust)
                127.0.0.1:9911                                  Lexer → Parser → VM

Components

Component	Language	Purpose
cortex-engine	Rust	Compiler (lexer, parser, type checker, bytecode) + VM + CLI
cortex-daemon	Go	Native IPC host, WebSocket server, background scheduler
cortex-shell	Rust	Desktop WebView host (Tauri WRY) — Phase 3
cortex-pwa	Svelte + TS	Demo PWA frontend — Phase 3
cortex-android	Kotlin	Android companion app (TPT Core) — Phase 4

Quick Start

# Phase 1 — compile a Cortex script
cargo run -p cortex-engine -- compile examples/hello.ctx --allow=native.log

# Phase 2 — run a Cortex script
cargo run -p cortex-engine -- run examples/hello.ctx --allow=native.log

The Cortex Language

task syncNotes(userId: string) -> void {
    let notes: list<string> = native.db.query("SELECT * FROM notes WHERE synced = 0");

    if native.net.isConnected() {
        let payload: string = native.json.encode(notes);
        native.http.post("https://api.example.com/sync", payload);
    }

    native.log("Done");
}

Roadmap

• Phase 1 (Weeks 1–3): Core compiler — lexer, parser, type checker, CLI
• Phase 2 (Weeks 4–6): VM — bytecode compiler, stack-based execution, op budgeting
• Phase 3 (Weeks 7–9): Native bridging — Go daemon, IPC, Svelte PWA
• Phase 4 (Weeks 10–12): Pulse daemon, background scheduler, Android companion

Distribution

TPT Core (Android) is distributed via direct APK download — no app store required.
