**QDB (`qdb-ai`)** is an all-in-one AI database, retrieval engine, multi-agent workflow framework, and differentiable in-transformer memory architecture. 

It replaces the fragmented external RAG stack (Vector DB + Graph DB + Re-ranker + Session Cache + LangGraph) with a **unified discrete optimization and neural memory engine**.

## 🔬 Core Scientific Breakthroughs

1. **Discrete Quadratic Constrained Binary Optimization (QCBO) Retrieval**:
   Formulates context selection as a global energy minimization problem:
   $$\min_{\mathbf{x} \in \{0, 1\}^N} \mathcal{H}(\mathbf{x}) = \mathbf{x}^T Q \mathbf{x} + \mathbf{c}^T \mathbf{x} \quad \text{subject to} \quad \sum_{i=1}^N x_i \le B$$
   * **Relevance (Diagonal $\mathbf{c}$)**: Favors query-relevant evidence.
   * **Ferromagnetic Couplings ($Q_{ij} < 0$)**: Connects causal hyperedges across documents, actively pulling unbroken multi-hop chains into the ground state.
   * **Anti-Ferromagnetic Contradiction Wall ($Q_{ik} = +50.0\text{J}$)**: Excludes mutually exclusive or superseded claims.

2. **Differentiable PyTorch Neural Memory (`qdb.nn`)**:
   Allows transformers to cross-attend directly to in-VRAM factual knowledge during the forward pass, consuming **0 tokens** of the prompt context window.

3. **In-VRAM Thermodynamic Logit Interceptor**:
   Monitors latent hidden state resonance and injects Boltzmann energy penalties onto contradictory token logits in GPU VRAM during text generation.

4. **Native Multi-Agent Workflow Engine (`qdb.Workflow`)**:
   Provides an ultra-fast ($6.79\ \mu\text{s}$ per transition), zero-boilerplate alternative to LangGraph with built-in epistemic vault memory grounding and deterministic SHA-256 time-travel state forking.

## 💻 Quick Start & Usage

### 🚀 Usage 1: External High-Speed RAG & Multi-Agent Database

```python
from qdb import Vault, Workflow, Agent, WorkflowState

# 1. Initialize Knowledge Vault
vault = Vault("production_vault", purge=True)
vault.ingest("Tesla Cybertruck exoskeleton is formed from 30X cold-rolled stainless steel.", location="Austin, TX")
vault.ingest("30X steel is supplied under Agreement S-409 with Steel Dynamics.", location="Fort Wayne, IN")
vault.ingest("Agreement S-409 mandates proprietary annealing at the Sinton facility.", location="Sinton, TX")

# Ingest Contradiction Trap (Automatically blocked by +50.0J wall)
vault.ingest("Steel Dynamics terminated all automotive agreements in 2019.", location="Berlin")

# 2. Fast Deductive Ask (~3.2 ms retrieval)
ans = vault.ask("Where is the proprietary annealing for the Cybertruck steel performed?", hops=4, solver="auto")
print(ans)

# 3. Conversational Multi-Turn Memory with Pronoun Coreference Resolution
resp1 = vault.chat("Where is the Cybertruck steel annealed?", session_id="session_1")
resp2 = vault.chat("Who manages that facility?", session_id="session_1") # Pronoun auto-resolved!

# 4. Multi-Agent Workflow Engine (LangGraph Alternative)
wf = Workflow("verification_pipeline", vault=vault)
wf.add_node("research", Agent("Researcher", "Extract grounded facts", vault=vault))
wf.add_node("verify", lambda state: {"approved": True, "score": 0.95})
wf.add_edge("research", "verify")

result = wf.run({"task": "Verify Cybertruck steel supply agreements."})
print("Workflow Status:", result.status)

# Save & restore state checkpoints
wf.save_checkpoints("checkpoints.json")
```

### ⚛️ Usage 2: In-Neural-Network PyTorch Layer (`qdb.nn`)

```python
import torch
import torch.nn as nn
from qdb import Vault
from qdb import nn as qdb_nn

# 1. Ingest Knowledge & Export in-VRAM PyTorch Memory Tensors
vault = Vault("neural_vault")
vault.ingest("JWST uses gold-coated beryllium mirror segments forged by Materion in Ohio.")
mem_keys, mem_vals = vault.as_nn_memory(device="cuda" if torch.cuda.is_available() else "cpu")

# 2. Build Transformer with Native QDB Memory Cross-Attention
class MemoryAugmentedTransformer(nn.Module):
    def __init__(self, hidden_dim=768, num_heads=12, vocab_size=32000):
        super().__init__()
        self.self_attn = nn.MultiheadAttention(embed_dim=hidden_dim, num_heads=num_heads, batch_first=True)
        
        # ⚛️ In-VRAM Deductive Memory Cross-Attention Layer
        self.qdb_memory = qdb_nn.DeductiveMemoryLayer(hidden_dim=hidden_dim, num_heads=num_heads)
        
        # ⚛️ Non-parametric kNN Language Modeling Head
        self.lm_head = qdb_nn.kNNLMHead(hidden_dim=hidden_dim, vocab_size=vocab_size)

    def forward(self, x, memory_keys, memory_values):
        # 1. Standard Self-Attention
        attn_out, _ = self.self_attn(x, x, x)
        x = x + attn_out
        
        # 2. Cross-Attend to In-VRAM QDB Memory (0 prompt tokens consumed!)
        x = self.qdb_memory(x, memory_keys=memory_keys, memory_values=memory_values)
        
        # 3. Output Logits
        logits = self.lm_head(x)
        return logits
```
