## What is Cortex?

Cortex is a **drop-in persistent memory engine** for AI agents. It solves the three failure modes of naive AI memory: identity drift, junk accumulation, and no lifecycle.

**Key differentiators:**

- 🪨 **Cornerstones** — always-on identity memories that inject at the start of every session, bypassing semantic retrieval. Your agent's core identity is guaranteed to be present.
- 🌙 **Dream Cycles** — async memory consolidation via a persistent CircadianEngine. Memories are scored, promoted, decayed, and synthesized while your agent sleeps.
- 👥 **Multi-tenant** — full `owner_id` isolation. One Cortex instance serves multiple users with complete memory separation.
- 🔌 **Provider-agnostic** — pluggable LLM and embedding providers: Venice, Mistral, Google, Voyage. Switch without re-embedding.

**Production-ready out of the box:**

- 🚀 One-command Fly.io deploy via `cortex-fly.toml`
- 💾 Litestream continuous backup + GitHub Actions daily snapshot
- 📡 Sentry error tracking + performance spans

---

## What's New in v1.4.0

> v1.4.0 is the **memory scoping + entity intelligence** release.

- 🔭 **Entity-scoped retrieval** — filter memories by `entity_id` and `entity_type` on retrieve, search, and browse endpoints. Your agent can now recall memories about specific people, projects, or concepts (#923, #931)
- ⏳ **Temporal claims** — memories have `valid_from`/`valid_to` lifecycle. Expired claims are excluded by default; include with `include_expired=true`. New `GET /memories/timeline` endpoint for subject history (#925, #931)
- 👥 **Entity visibility lifecycle** — entities progress through `extracted → promoted → active` states based on `connection_count`. Dashboard-ready entity intelligence (#933, #938)
- 🎭 **Peer promotion** — peers promoted to canonical actor identities with `peer_type`, `status`, `permissions_json`, and `connection_count`. First-class support for multi-actor systems (#932, #941)
- 🧹 **Extraction quality** — predicate filter removes junk claims (code artifacts, bot names, ephemeral actions) + prompt tuning for better extraction (#929, #940)
- 🌐 **Cortex-proxy** — Supabase edge function for CORS-free dashboard access with path traversal protection (#928, #937)

**Previous highlights (v1.3.x):**

- 🦛 **Hippo LCM** — Lossless Context Management: compaction, summarization, retrieval (#869–#871)
- 🪨 **Cornerstone always-on injection** — identity cornerstones inject unconditionally every session (#733)
- 🔑 **Static API key auth** — `X-Cortex-API-Key` header replaces JWT complexity (#737)
- 🌙 **Dream engine persistent scheduler** — CircadianEngine starts at server boot (#776)

See the full [CHANGELOG](CHANGELOG.md) for all fixes and changes.

## Architecture

Cortex processes memory through a **five-layer pipeline**:

```
Capture → Extract → Reconcile → Retrieve → Dream
```

| Layer | What It Does |
|-------|-------------|
| **Capture** | Intercepts conversation turns and session events |
| **Extract** | LLM-powered claim extraction with noise filtering |
| **Reconcile** | Smart conflict resolution: ADD / UPDATE / SUPERSEDE / NOOP |
| **Retrieve** | Hybrid BM25 + vector search with Reciprocal Rank Fusion |
| **Dream** | Async consolidation, decay, synthesis, and contradiction resolution |

### Cornerstone Layer

Cornerstones are **identity memories that inject first, every session**. They bypass semantic retrieval entirely — they are always present, always loaded, and protected from accidental deletion. This is the foundation of identity preservation.

```
Session Start
     │
     ▼
┌─────────────────────┐
│  Cornerstone Load   │  ← unconditional, always first
│  (identity anchors) │
└──────────┬──────────┘
           │
           ▼
┌─────────────────────┐
│  Semantic Retrieval │  ← query-dependent context
│  (BM25 + vector)    │
└──────────┬──────────┘
           │
           ▼
┌─────────────────────┐
│  Context Injection  │
│  (system prompt)    │
└─────────────────────┘
```

### Provider System

Cortex uses a pluggable provider system for both LLM and embedding operations:

| Capability | Default Provider | Alternatives |
|---|---|---|
| LLM extraction | Venice (`mistral-small-3-2-24b-instruct`) | Google, OpenAI, Anthropic |
| Embeddings | Venice BGE-M3 (1024-dim) | Voyage, Google, OpenAI |
| Reranking | Voyage | — |

Switch providers at runtime via config or env vars — no re-embedding required.

---

## Quick Start

### Environment Variables

```bash
# Required
export CORTEX_API_KEY=your-secret-key

# Provider (Venice — default)
export VENICE_API_KEY=your-venice-key
export CORTEX_EMBEDDING_MODEL=text-embedding-bge-m3

```

### CLI

```bash
# Initialize a new memory store
evaos init

# Teach it something
evaos remember "Andrew is the founder of 100Yen Org. He lives in Bangkok."

# Ask it later
evaos recall "Where does Andrew live?"
# → Andrew lives in Bangkok. He is the founder of 100Yen Org.

# Check config
evaos config show

# Validate provider config
evaos config validate
```

### Python SDK

```python
import asyncio
from evaos import Cortex

async def main():
    cortex = Cortex(db_path="my_memory.db")
    await cortex.initialize()

    # Start a session — cornerstones inject automatically
    await cortex.wake(session_id="session_001")

    # Store information — claim extraction happens automatically
    await cortex.remember("Andrew is the founder of 100Yen Org. He lives in Bangkok.")

    # Retrieve relevant memories for an LLM prompt
    context = await cortex.retrieve("Where does Andrew live?")
    print(context.context_block)
    # → "Andrew lives in Bangkok. He is the founder of 100Yen Org."

    # End the session — dream cycle consolidates
    await cortex.sleep(session_id="session_001")

asyncio.run(main())
```

## Features

### 🧠 Memory Pipeline

| Layer | What It Does |
|-------|-------------|
| **Extraction** | LLM-powered claim extraction with noise filtering (skips "changed line 47 of auth.py") |
| **Entity Resolution** | Fuzzy deduplication — "Andrew", "andrew", "@andrew" → same person |
| **Reconciliation** | Smart conflict resolution: ADD / UPDATE / SUPERSEDE / NOOP |
| **Cornerstones** | Always-on identity anchors — inject first, every session, no keywords needed |
| **Token Budget** | Assembles memory context within configurable token ceilings |

### 🌙 Dream Cycles

A persistent `CircadianEngine` starts at server boot and runs async memory consolidation:
- **Standard Dream** — Ebbinghaus decay, contradiction resolution, cross-session synthesis
- **Deep Dream** — Generative memory synthesis; Gen1 Soul restoration (new in v1.3.0)
- **Extraction Failure Queue** — Failed extractions retried automatically in dream cycles

### 🔑 Auth & Multi-Tenancy

- **Static API key** — `X-Cortex-API-Key` header. Simple, secure, no JWT complexity.
- **Multi-tenant** — `owner_id` resolved per-request from API key. Complete memory isolation between users.
- **Soft-delete** — Deleted memories retained for 90 days, restorable via API. Dream cycle purges after expiry.

### 📋 Commitments & Open Loops

First-class tracking of agent commitments and unresolved threads. Both inject into session boot context for continuity across sessions.

### 💬 Dialectic Engine

Ask your memory natural-language questions. Fast path for simple lookups, agentic multi-step QueryPlanner for complex reasoning across your memory graph.

### 🔍 Hybrid Retrieval

BM25 full-text search + vector similarity with Reciprocal Rank Fusion. Optional Voyage reranking for high-stakes queries.

### 📡 Observability

- **Sentry** — error tracking + performance spans in wake pipeline and retrieval
- **Health endpoint** — version, dream cycle timestamp, system status
- **Metrics** — pipeline counters, histograms, gauges, quality gates

### 🔌 Five Interfaces

| Interface | Use Case |
|-----------|----------|
| **CLI** | `evaos remember`, `evaos recall`, `evaos ask`, `evaos dream`, `evaos config` |
| **HTTP API** | FastAPI REST server — `evaos serve` |
| **MCP Server** | Model Context Protocol for agent frameworks — `evaos mcp` |
| **TypeScript SDK** | `@evaos/client` — typed client for Node.js applications |
| **OpenClaw Plugin** | `cortex` — drop-in memory plugin for OpenClaw agents |

---

## OpenClaw Plugin

Cortex ships an [OpenClaw](https://openclaw.com) plugin (`cortex`) that bridges your agent's memory to a running Cortex instance.

```jsonc
// openclaw.plugin.json (included in openclaw-plugin/)
{
  "id": "cortex",
  "kind": "memory"
  // configSchema: cortexUrl, apiKey, ownerId, autoRecall, autoCapture, ...
}
```

**What it does:**
- **before_agent_start** — loads cornerstones unconditionally, then retrieves semantic context
- **agent_end** — captures conversation as new memories (fire-and-forget)
- **session_start / session_end** — calls wake/sleep for session lifecycle

**Tools exposed:** `cortex_search`, `cortex_remember`, `cortex_forget`, `cortex_update_commitment`, `cortex_resolve_open_loop`

See [`openclaw-plugin/`](openclaw-plugin/) for full source and configuration schema.
