Sulcus v3.5.5 — Cloud fallback + Plugin fixes

What's New

Plugin (openclaw-sulcus)

• Cloud-first init: Cloud-only users no longer need local dylibs (v3.5.3)
• Cloud HTTP fallback: Lightweight stateless HTTP client for serverUrl+apiKey users (v3.5.0)

• Better diagnostics: Startup summary shows backend mode + config status (v3.5.1)
• Auto-download wizard: npx @digitalforgestudios/openclaw-sulcus configure downloads platform binaries (v3.4.0)

Prebuilt Binaries

• sulcus-macos-x64.tar.gz — Intel Mac (libsulcus_store.dylib + libsulcus_vectors.dylib)
• sulcus-linux-x64.tar.gz — Linux x86_64 (libsulcus_store.so + libsulcus_vectors.so)

Still Needed

• macOS ARM64 (Apple Silicon)
• Linux ARM64

Install

npm install @digitalforgestudios/openclaw-sulcus@3.5.5
npx @digitalforgestudios/openclaw-sulcus configure

Sulcus v3.4.0 — Architecture Refactor + Easy Button

What's New

Architecture Refactor

• Crate restructuring: sulcus-local → sulcus, sulcus-embed → sulcus-store + sulcus-vectors
• New shared crates: sulcus-core, sulcus-types for clean separation of concerns
• WASM SIU: Client-side memory classification via WebAssembly
• Server: libsulcus_vectors.so now ships in the container — semantic search fully operational

OpenClaw Plugin v3.4.0

• One-command setup: npx @digitalforgestudios/openclaw-sulcus configure
• Auto-downloads prebuilt binaries for your platform
• Everything off by default — full opt-in, privacy-safe
• No dynamic code execution — ClawHub scanner clean
• Config-driven hook dispatch with hooks.defaults.json
