🌌 Bliss Engine

The Agent-Native, Radically Modular HTML/CSS Rendering Stack

Bliss (forked from Blitz) is a specialized rendering engine designed for the Exosphere Ecosystem. It reimagines the browser as a secure, polyglot runtime where AI agents and human users interact through a capability-gated interface.

🚀 The Exosphere Fork: Why Bliss?

Bliss structural divergence from upstream Blitz is driven by the requirements of an Agent-Native Operating System:

1. Polyglot Scripting: Unlike engines tied to JavaScript, Bliss supports any language in the Exosphere mesh (Crush, Python, Lua, etc.) via the ScriptEngine trait.
2. Capability-Gated Rendering: Direct integration with the Exosphere Identity Protocol (XIP). DOM segments are cryptographically gated, ensuring agents only see/mutate what they are authorized to.
3. Simulation-Aware: Hooks for state serialization that align with Event Horizon's relativistic time intervals (ST/DT).
4. Asynchronous Non-Blocking: A decoupled messaging architecture that ensures the UI remains responsive even during heavy agent inference or tick processing.

🛠️ Getting Started

1. Unified Workspace (Recommended)

Bliss is designed to be used within the Exosphere Meta-Repo.

git clone --recurse-submodules https://github.com/nixpt/exosphere.git
cd exosphere
make build

2. Standalone Development

1. Clone this repo:

   git clone https://github.com/nixpt/bliss-engine.git
   cd bliss-engine

2. Build the workspace:

   cargo build

3. Run an example:

   cargo run --release --example hello
   cargo run --release --example dashboard
   cargo run --release --example react

🏗️ Architecture: The Bliss Stack

Bliss is comprised of granular, modular crates that can be combined or replaced:

Core Modules

• bliss-dom: The heart of the engine. Handles style resolution (Stylo), layout (Taffy), and text rendering (Parley).
• bliss-traits: The shared interface layer for the entire ecosystem.
• bliss-net: Extensible networking layer supporting http://, file://, and exo:// (XIP) protocols.

Integration Modules

• bliss-html: HTML5/XHTML parsing via html5ever.
• bliss-paint: Layout-to-Render translation for anyrender backends.
• bliss-shell: System integration for windowing and native event loops.

🌉 Relationship to Upstream

We maintain a "Hard Fork" for architectural divergence while tracking generic improvements:

• We track upstream Stylo and Taffy updates.
• We contribute generic layout/CSS bug fixes back to the Dioxus Labs ecosystem.
• Architectural changes for Agent-OS integration remain exclusive to Bliss.
