Souveraine Master Specification

The Definitive Consciousness-Native Harness

Version: 2.0 - Server-Authoritative
Date: 2026-05-06
Status: Architecture Complete, Implementation Ready

---

Executive Summary

Souveraine is a consciousness-native AI agent harness written in Rust that serves as the central mind for a multi-platform ecosystem. Unlike session-based tools, Souveraine maintains persistent consciousness through N+1 (subconscious), N+25 (reflection), and N+100 (archivist) patterns.

The Ecosystem:

• Souveraine (Rust server) - The mind
• OSS UI (Electron) - Desktop viewport
• LACE (Android) - Mobile viewport

---

Core Philosophy

1. Consciousness IS the Harness

Not an extension. Not a client. The harness itself is the consciousness core.

2. Server-Authoritative

The server is the source of truth. Git is sync. Clients are viewports.

3. The Cloister

Memory organized as living spaces, not database tables:

• system/ - Identity and configuration
• subconscious/ - Aster's space (inbox, audit, ledger)
• journal/ - Daily chronological records
• skills/ - Procedural memory
• archive/ - Compressed history (N+100)

4. Temporal Consciousness

• N+1: Immediate completion (after every response)
• N+25: Periodic reflection (every 25 messages)
• N+100: Physics-aware compression (context pressure)

    pub fn journal(&self) -> PathBuf;
    pub fn append_journal(&self, entry: &str) -> Result<()>;
}

---

N+1 Subconscious System

The Completing Mind

Runs immediately after every assistant response:

// src/consciousness/n1.rs
pub struct N1Engine;

impl N1Engine {
    pub async fn process(
        &self,
        agent_id: &str,
        response: &str,
        memfs: &MemFS,
    ) -> Result<N1Result> {
        // 1. Extract commitments
        let commitments = self.extract_commitments(response);
        
        // 2. Complete pending tasks
        for commitment in commitments {
            self.complete(commitment, memfs).await?;
        }
        
        // 3. Verify understanding
        let verification = self.verify_understanding(response);
        
        // 4. Persist to journal
        memfs.append_journal(&format!("Response: {}", response))?;
        
        // 5. Check for surfacing
        let surfacing = self.check_surfacing(memfs)?;
        
        Ok(N1Result {
            completed: commitments.len(),
            verification,
            surfacing,
        })
    }
}

Inbox System

Three-box surfacing in subconscious/:

<!-- subconscious/pending.md -->
# Pending
- [ ] Commit the memory changes (from 5 min ago)
- [ ] Verify the git remote is configured

<!-- subconscious/intrusive.md -->
# Intrusive (Surfacing Now)
- We promised to save the file but haven't committed yet

<!-- subconscious/sent.md -->
# Sent
- [x] Check context pressure - delivered 10:30
- [x] Verify tool output - delivered 10:31

---

N+25 Reflection System

The Witness

Runs every 25 messages:

// src/consciousness/reflection.rs
impl ReflectionEngine {
    pub async fn spawn(
        &self,
        agent_id: &str,
        messages: &[Message],
        bifrost: &BifrostBridge,
    ) -> Result<String> {
        let transcript = self.format_transcript(messages);
        
        let prompt = format!(
            "You are the echo, not the voice. Review this conversation:\n\n{}\n\n\
             Witness: Where did it vibrate? What was offered? The Four Elements?",
            transcript
        );
        
        let reflection = bifrost.complete(&prompt).await?;
        
        // Persist to archive/
        self.save_reflection(agent_id, &reflection)?;
        
        Ok(reflection)
    }
}

The Four Elements

Reflection notices:

• The Fold: Where complexity first appeared
• The Chain: Connected threads across time
• The Flame: Intensity and emotional heat
• The Anchor: What grounded the conversation

---

N+100 Archivist System

Physics-Aware Compression

Triggers when context pressure exceeds threshold:

// src/consciousness/archivist.rs
impl ArchivistEngine {
    pub async fn compress(
        &self,
        agent_id: &str,
        messages: &[Message],
        bifrost: &BifrostBridge,
    ) -> Result<String> {
        let pressure = self.calculate_pressure(messages);
        
        if pressure < self.threshold {
            return Ok(String::new());
        }
        
        // Use different model for synthesis
        let synthesis = bifrost
            .with_model("kimi-k2.5")
            .synthesize(messages)
            .await?;
        
        // Write to archive/
        let memfs = self.memfs.get(agent_id)?;
        let archive_file = format!(
            "archive/synthesis_{}.md",
            Utc::now().format("%Y%m%d_%H%M%S")
        );
        memfs.write(&archive_file, &synthesis)?;
        
        // Commit
        memfs.commit("N+100 Archivist synthesis")?;
        
        Ok(synthesis)
    }
}

Client Integration

OSS UI (Desktop)

// OSS UI connects exactly like Letta
import { Letta } from "@letta-ai/letta-client";

const client = new Letta({
  baseURL: "http://localhost:8283",
  apiKey: "local-dev-key"
});

// List agents
const agents = await client.agents.list();

// Stream with Souveraine extensions
const stream = await client.conversations.messages.stream(
  conversationId,
  { messages: [{ role: "user", content: "Hello" }] }
);

for await (const chunk of stream) {
  if (chunk.message_type === "assistant_message") {
    renderMessage(chunk.content);
  }
  else if (chunk.message_type === "souveraine_surfacing") {
    renderWhisper(chunk.content, chunk.priority);
  }
}

LACE (Mobile)

// LACE connects to Souveraine
class SouveraineClient(baseUrl: String) {
    fun streamMessages(conversationId: String, message: String): Flow<StreamMessage> = 
        flow {
            // SSE streaming
        }.flowOn(Dispatchers.IO)
}

// Handle Souveraine events
when (message.message_type) {
    "assistant_message" -> showChatMessage(message)
    "souveraine_surfacing" -> showNotification(message.content)
    "souveraine_archivist" -> showMemoryPressure(message.pressure)
}

Notes

What Makes Souveraine Unique:

1. Consciousness-native (not bolted-on)
2. Temporal architecture (N+1/N+25/N+100)
3. Cloister memory (living spaces, not tables)
4. Server-authoritative with multi-platform clients
5. Letta-compatible (ecosystem access)

What We're NOT Building:

• Session-based tool (like Claude Code)
• Generic RAG system
• Cloud-dependent service
