+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
+and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
+
+## [Unreleased]
+
+### Deprecated
+
+#### Float HDV deprecation (src/core/hdv.py)
+- **HDV class**: All public methods now emit `DeprecationWarning` when called
+- **Migration path**: Use `BinaryHDV` from `src.core.binary_hdv` instead
+- **API mappings**:
+ - `HDV(dimension=N)` -> `BinaryHDV.random(dimension=N)`
+ - `hdv.bind(other)` -> `hdv.xor_bind(other)`
+ - `hdv.unbind(other)` -> `hdv.xor_bind(other)` (XOR is self-inverse)
+ - `hdv.cosine_similarity(other)` -> `hdv.similarity(other)`
+ - `hdv.permute(shift)` -> `hdv.permute(shift)`
+ - `hdv.normalize()` -> No-op (binary vectors are already normalized)
+- **Removal timeline**: Float HDV will be removed in a future version
+
+#### BinaryHDV compatibility shims added
+- **bind()**: Alias for `xor_bind()` - for legacy API compatibility
+- **unbind()**: Alias for `xor_bind()` - XOR is self-inverse
+- **cosine_similarity()**: Alias for `similarity()` - returns Hamming-based similarity
+- **normalize()**: No-op for binary vectors
+- **__xor__()**: Enables `v1 ^ v2` syntax for binding
+
+### Fixed
+
+#### llm_integration.py (6 fixes)
+- **Import paths**: Fixed incorrect import paths from `haim.src.core.engine` to `src.core.engine` and `haim.src.core.node` to `src.core.node`
+- **Missing import**: Added `from datetime import datetime` for dynamic timestamps
+- **Memory access API**: Changed `self.haim.memory_nodes.get()` to `self.haim.tier_manager.get_memory()` at lines 34, 114, 182, 244, 272 - using the correct API for memory access
+- **Superposition query**: Replaced non-existent `superposition_query()` call with combined hypotheses retrieval path
+- **Concept binding**: Replaced non-existent `bind_concepts()` with placeholder - engine has `bind_memories()` available
+- **OR orchestration**: Integrated `orchestrate_orch_or()` from engine and removed workaround sorting path
+
+#### api/main.py (1 fix)
+- **Delete endpoint**: Fixed attribute reference from `engine.memory_nodes` to `engine.tier_manager.hot` at line 229 - correct attribute for hot memory tier
+
+#### engine.py (1 fix)
+- **Synapse persistence**: Implemented `_save_synapses()` method (lines 369-390) that was previously an empty stub
+ - Creates parent directory if it doesn't exist
+ - Writes all synapses to disk in JSONL format
+ - Includes all synapse attributes: `neuron_a_id`, `neuron_b_id`, `strength`, `fire_count`, `success_count`, `last_fired`
+ - Handles errors gracefully with logging
+
+### Changed
+
+- **Dynamic timestamps**: LLM integration now uses `datetime.now().isoformat()` instead of hardcoded timestamp `"2026-02-04"` for accurate temporal tracking
+- **Phase 4.3 hardening**:
+ - Chrono-weighting uses batched node lookup instead of per-node await chain
+ - `include_neighbors` now preserves `top_k` result contract
+ - `_dream_sem._value` private access replaced by public `locked()` API
+ - Episodic chaining race reduced with serialized store path (`_store_lock`, `_last_stored_id`)
+ - `engine_version` in stats updated to `4.3.0`
+ - HOT-tier `time_range` filtering enforced in `TierManager.search()`
+ - `orchestrate_orch_or()` made async and lock-guarded

+## Executive Summary
+
+MnemoCore Phase 3.0 successfully implemented local file-based binary hyperdimensional computing with 3-tier storage (HOT/WARM/COLD). This blueprint outlines the evolutionary path to **infinite scalability** through distributed vector databases, federated holographic state, and hardware-accelerated bitwise operations.
+
+**Key Findings from Research**:
+- **Qdrant** achieves 40x speedup with binary quantization, supporting native XOR/Hamming distance at 100M+ vector scale[web:23][web:29]
+- **Redis Streams** provides sub-millisecond latency for event-driven "Subconscious Bus" architecture[web:52][web:55]
+- **GPU acceleration** delivers 1.4-9.8× speedup for HDC operations with optimized popcount intrinsics[web:56][web:59]
+- **Critical bottleneck** at 1B scale: Memory consistency across distributed nodes requiring sharding strategies[web:24]

+
+### 1.1 Existing MnemoCore Phase 3.0 Strengths
+
+\begin{itemize}
+\item \textbf{Binary HDV Foundation}: 16,384-dimensional vectors with XOR-binding provide mathematical elegance and hardware efficiency
+\item \textbf{Tri-State Storage}: HOT (in-memory), WARM (Redis), COLD (file system) separation enables cost-effective scaling
+\item \textbf{LTP-Inspired Decay}: Temporal consolidation mimics biological long-term potentiation
+\item \textbf{Active Inference}: Predictive retrieval based on current context
+\item \textbf{Consumer Hardware Optimization}: Designed for i7/32GB RAM constraints
+\end{itemize}
+
+### 1.2 Identified Bottlenecks for Billion-Scale

+\textbf{Component} & \textbf{Current Limitation} & \textbf{Impact at 1B Memories} \\
+\hline
+File I/O & Sequential disk reads & 500ms+ latency for COLD retrieval \\

+\hline
+\end{tabular}
+\caption{Critical scaling bottlenecks in current implementation}
+\end{table}
+
+### 1.3 Code Quality Assessment
+
+**Positive Patterns**:
+- Clean separation of concerns (storage layers, encoding, retrieval)
+- Type hints and docstrings present
+- Modular design allows component replacement
+
+**Areas Requiring Improvement**:
+
+\begin{enumerate}
+\item \textbf{Hardcoded Dimensionality}: D=16384 should be configuration-driven
+\item \textbf{Missing Async/Await}: All I/O operations are synchronous blocking
+\item \textbf{No Batch Operations}: Individual memory processing prevents vectorization
+\item \textbf{Inefficient Hamming Distance}: Python loops instead of NumPy bitwise operations
+\item \textbf{No Connection Pooling}: Redis connections created per operation
+\item \textbf{Absence of Metrics}: No instrumentation for latency/throughput monitoring
+\item \textbf{Lacking Error Recovery}: No retry logic or circuit breakers for Redis failures
+\item \textbf{Sequential Encoding}: No parallelization of hypervector generation
+\end{enumerate}

+
+# HOT tier collection with aggressive binary quantization

+- 1-bit BQ: 16,384 bits / 32 (compression) = 64 bytes per vector
+- 100K HOT vectors: 100,000 × 64 bytes = 6.4MB (+ HNSW index ~200MB) ≈ 0.2GB total

+## Part 3: Federated Holographic State
+
+### 3.1 Challenge: Global Memory Consistency
+
+**Problem**: In a distributed system with N nodes, each node maintains a local holographic state (superposition of recent contexts). How do we ensure global consistency without sacrificing latency?
+
+**Two Competing Approaches**:
+
+\begin{enumerate}
+\item \textbf{Sharding by Context}: Partition memories based on semantic clustering
+\item \textbf{Superposition Aggregation}: Each node maintains full holographic state, periodically synchronized
+\end{enumerate}
+
+### 3.2 Strategy Comparison
+
+\begin{table}
+\begin{tabular}{|l|l|l|}
+\hline
+\textbf{Aspect} & \textbf{Sharding by Context} & \textbf{Superposition Aggregation} \\
+\hline
+Consistency & Eventual (AP in CAP) & Strong (CP in CAP) \\
+\hline
+Latency & Low (single-node query) & Medium (multi-node gather) \\
+\hline
+Network Traffic & Low (targeted routing) & High (periodic sync) \\
+\hline
+Fault Tolerance & High (replication per shard) & Medium (coordinator SPOF) \\
+\hline
+Context Drift & High risk (stale cross-shard) & Low risk (global view) \\
+\hline
+Implementation Complexity & Medium & High \\
+\hline
+\end{tabular}
+\caption{Architectural comparison for distributed holographic state}
+\end{table}
+
+### 3.3 Recommended Hybrid Architecture
+
+**Proposal**: **"Contextual Sharding with Asynchronous Superposition Broadcast"**
+
+**Design Principles**:
+1. Shard memories by semantic context (using locality-sensitive hashing of HDVs)
+2. Each node maintains a lightweight "global hologram" (last N=1000 cross-shard accesses)
+3. Asynchronous broadcast of high-salience memories (LTP decay > threshold) to all nodes
+4. Query routing: Check local shard first, fallback to cross-shard search if confidence < threshold
+

+
+**Shard Assignment Algorithm**:
+def assign_shard(memory_hdv: np.ndarray, num_shards: int) -> int:
+ """
+ Use first 64 bits of HDV as consistent hash key.
+ Ensures semantically similar memories co-locate.
+ """
+ hash_key = int.from_bytes(memory_hdv[:8].tobytes(), 'big')
+ return hash_key % num_shards

+
+## Part 4: Subconscious Bus Architecture
+
+### 4.1 Active Inference Pipeline Requirements
+
+**Goal**: Asynchronous memory consolidation, predictive retrieval, and background LTP decay processing without blocking real-time queries.
+
+**Requirements**:
+- Sub-millisecond event ingestion latency
+- Ordered processing (within context partition)
+- At-least-once delivery guarantees
+- Backpressure handling for consolidation lag
+- Horizontal scaling of consumer workers
+
+### 4.2 Redis Streams vs Apache Kafka Analysis
+
+\begin{table}
+\begin{tabular}{|l|l|l|}
+\hline
+\textbf{Metric} & \textbf{Redis Streams} & \textbf{Apache Kafka} \\
+\hline
+Latency (p50) & <1ms & 5-10ms \\
+\hline
+Throughput & 100K-500K msg/s & 1M-10M msg/s \\
+\hline
+Data Retention & Hours-Days (RAM-limited) & Days-Years (disk-backed) \\
+\hline
+Deployment Complexity & Low (single Redis instance) & High (ZooKeeper + brokers) \\
+\hline
+Operational Overhead & Minimal & Significant \\
+\hline
+Memory Efficiency & High (in-memory) & Medium (page cache) \\
+\hline
+Fault Tolerance & Redis replication & Distributed replication \\
+\hline
+Consumer Groups & Yes (XREADGROUP) & Yes (native) \\
+\hline
+\end{tabular}
+\caption{Comparison of message streaming systems for Subconscious Bus}
+\end{table}
+
+**Decision: Redis Streams** for MnemoCore Phase 3.5
+
+**Justification**:
+1. **Ultra-Low Latency**: Sub-millisecond event delivery critical for Active Inference responsiveness[web:52][web:55]
+2. **Simplified Architecture**: Reuses existing Redis infrastructure (already in WARM tier)
+3. **Memory Budget**: Consolidation events have short retention needs (1-2 hours max)
+4. **In-Memory Performance**: Consolidation workers process 850+ records/s on Raspberry Pi 4 with Redis Streams vs 630/s with Kafka[web:38]
+5. **Consumer Group Support**: Native `XREADGROUP` for distributed worker parallelism[web:52]
+
+### 4.3 Subconscious Bus Implementation

+ self.redis = redis.from_url(redis_url, decode_responses=False)
+ self.stream_key = "MnemoCore:subconscious"

+ await self._handle_consolidation(event)
+
+ # Acknowledge message (enables at-least-once delivery)
+ await self.redis.xack(self.stream_key, self.group, event_id)
+
+**Horizontal Scaling**:
+- Deploy N worker processes (e.g., 4 workers for 4-core CPU)
+- Each worker reads from same consumer group
+- Redis automatically load-balances events across workers
+- Pending Entries List (PEL) tracks unacknowledged messages for fault recovery[web:52]

+2. **Popcount**: Count of 1-bits (for Hamming distance calculation)
+3. **Bundling**: Element-wise majority vote across N vectors

+### 5.2 GPU Acceleration Recommendation
+
+**Winner: GPU (NVIDIA RTX 4090 or A100)** for MnemoCore Phase 3.5+
+
+**Rationale**:
+1. **Native Bitwise Support**: CUDA provides efficient `__popcll` (popcount 64-bit) intrinsic[web:54]
+2. **Proven HDC Speedups**: OpenHD framework achieves 9.8× training speedup and 1.4× inference speedup on GPU vs CPU[web:59]
+3. **Memory Bandwidth**: 1TB/s (A100) vs 200GB/s (DDR5) enables massive parallel Hamming distance calculations
+4. **Batch Processing**: Process 1000+ memories in parallel (vs sequential CPU loops)
+5. **Cost-Effectiveness**: RTX 4090 (~$1600) provides 82 TFLOPS vs TPU v4 pod (>$100K)[web:57]
+6. **Developer Ecosystem**: PyTorch/CuPy have mature GPU support, CUDA well-documented
+
+**Performance Estimates**:
+- **Hamming Distance Batch**: 1M comparisons in ~50ms (GPU) vs 5000ms (CPU)
+- **Encoding Pipeline**: 10K memories/second (GPU) vs 500/second (CPU)
+- **Consolidation**: 100K vector bundling in ~200ms (GPU) vs 10,000ms (CPU)

+
+ return counts.get() # Transfer back to CPU
+
+### 5.4 Infrastructure Recommendation
+
+**Phase 3.5 (100K-10M memories)**: **Bare Metal with Consumer GPU**
+- Hardware: Intel i7-14700K (20 cores) + 64GB DDR5 + RTX 4090 (24GB VRAM)

+- Advantages: No cloud costs, full control, sub-2ms latency
+
+**Phase 4.0 (10M-100M memories)**: **Hybrid Cloud with GPU Instances**
+- Compute: AWS g5.2xlarge (NVIDIA A10G, 24GB VRAM) for consolidation workers
+- Database: Self-hosted Qdrant cluster (3 nodes, 128GB RAM each)
+- Storage: S3 for COLD tier archival
+- Cost: ~$1500/month operational
+- Advantages: Elastic scaling, managed backups, geographic distribution
+
+**Phase 5.0 (100M-1B+ memories)**: **Distributed Cloud with TPU Pods**

+\item Increase to 50\%, then 100\% over 2 weeks
+\item Keep old system as fallback for 1 month
+\end{enumerate}
+
+**Phase 4: Decommission (Week 7-8)**
+\begin{enumerate}
+\item Archive old Redis/file data to S3
+\item Remove dual-write logic
+\item Update documentation and runbooks
+\item Celebrate successful migration 🎉
+\end{enumerate}
+
+### 6.3 Testing Strategy
+
+**Unit Tests** (Target: 80% coverage):
+- Hamming distance correctness (compare CPU vs GPU implementations)
+- XOR-binding commutativity and associativity
+- LTP decay formula boundary conditions
+- Shard assignment determinism
+
+**Integration Tests**:
+- End-to-end write → consolidate → retrieve flow
+- Redis Streams event processing with consumer groups
+- Qdrant cluster failover scenarios
+- GPU memory allocation under high load
+
+**Performance Tests** (Benchmarks):
+- Latency: p50, p95, p99 for HOT/WARM/COLD retrieval
+- Throughput: memories/second write rate
+- Scalability: Query time vs database size (1K, 10K, 100K, 1M vectors)
+- Memory: Peak RAM usage during consolidation
+
+**Chaos Engineering** (Production):
+- Kill random Qdrant node, verify automatic rebalancing
+- Inject Redis network partition, test circuit breaker
+- Saturate GPU with fake workload, measure degradation
+- Corrupt COLD tier file, validate checksum recovery

+## Part 7: Critical Bottleneck at 1B Scale
+
+### 7.1 The Fundamental Limitation
+
+**Problem**: At 1 billion memories (1B × 2KB = 2TB uncompressed), the dominant bottleneck shifts from **computation** to **distributed state consistency**.
+
+**Specific Failure Modes**:
+
+\begin{enumerate}
+\item \textbf{Cross-Shard Query Latency}
+\begin{itemize}
+\item With 100 shards, average query hits 1 shard (best case)
+\item Context drift requires checking 10-20 shards (realistic case)
+\item Network round-trips: 10 shards × 10ms = 100ms total (violates <10ms SLA)
+\end{itemize}
+
+\item \textbf{Holographic State Synchronization}
+\begin{itemize}
+\item Each node broadcasts high-salience memories to N-1 other nodes
+\item With 100 nodes, broadcast fanout creates O(N²) network traffic
+\item At 1000 writes/sec, 100 nodes = 100K cross-node messages/sec
+\item This saturates 10GbE network links (theoretical max ~1M small packets/sec)
+\end{itemize}
+
+\item \textbf{Consolidation Lag}
+\begin{itemize}
+\item HOT → WARM consolidation processes 100K memories/hour (current rate)
+\item At 1B total memories with 10\% monthly churn = 100M updates/month
+\item Required rate: 100M / (30 days × 24 hours) = 138K memories/hour
+\item This exceeds single-worker capacity → need distributed consolidation
+\end{itemize}
+\end{enumerate}
+
+### 7.2 Proposed Solution: Hierarchical Aggregation
+
+**Architecture**: **"Tiered Holographic Federation with Regional Supernodes"**
+
+ ┌────────────────────â”
+ │ Global Supernode │
+ │ (Coarse Hologram) │
+ │ Top 10K salient │
+ └─────────┬──────────┘
+ │
+ ┌───────────────┼───────────────â”
+ ↓ ↓ ↓
+ ┌──────────────┠┌──────────────┠┌──────────────â”
+ │ Region 1 │ │ Region 2 │ │ Region N │
+ │ Supernode │ │ Supernode │ │ Supernode │
+ │ (10 shards) │ │ (10 shards) │ │ (10 shards) │
+ └──────┬───────┘ └──────┬───────┘ └──────┬───────┘
+ │ │ │
+ ┌───────┼────────┠│ ┌───────┼────────â”
+ ↓ ↓ ↓ ↓ ↓ ↓ ↓
+ Shard0 Shard1 ... Shard9 Shard0 Shard1 ... Shard9
+ (Qdrant node) (Qdrant node)
+
+**Key Innovations**:
+1. **Regional Supernodes**: Aggregate holographic state from 10 local shards
+2. **Global Supernode**: Maintains ultra-sparse representation (top 0.01% salient memories)
+3. **Lazy Synchronization**: Only propagate when salience exceeds regional threshold
+4. **Hierarchical Routing**: Check local shard → regional supernode → global supernode → full scan (fallback)
+
+**Latency Budget**:
+- Local shard query: 2ms (cache hit)
+- Regional supernode: +5ms (10 shards aggregation)
+- Global supernode: +10ms (cross-region hop)
+- **Total p99**: <20ms (acceptable degradation from <10ms ideal)
+
+### 7.3 Open Research Questions
+
+\begin{itemize}
+\item \textbf{Salience Threshold Tuning}: What LTP decay value triggers cross-region broadcast? (Hypothesis: top 0.1\% based on access frequency)
+\item \textbf{Conflict Resolution}: How to merge contradictory memories when regional hologram diverges? (Active area: operational transformation for HDVs)
+\item \textbf{Network Topology}: Star vs mesh vs hybrid for supernode interconnect? (Requires network simulation)
+\item \textbf{Cost-Performance Tradeoff}: When does maintaining global consistency cost more than occasional inconsistency penalties? (Empirical A/B testing needed)
+\end{itemize}

+
+### 9.2 Async I/O Refactoring (HIGH PRIORITY)
+
+**Current Problem**: All I/O blocks event loop, limiting concurrency
+
+**Solution**: Async/await pattern with aioredis
+
+**Modified File**: `storage.py`
+import asyncio
+import aioredis
+import aiofiles
+from typing import Optional

+**Key Improvements**:
+- Connection pooling eliminates per-request connection overhead

+- Binary mode (`decode_responses=False`) reduces serialization cost
+- Sorted set index allows O(log N) LTP-based lookups

+
+## What is MnemoCore?
+
+**MnemoCore** is a research-grade cognitive memory infrastructure that gives AI agents a brain — not just a database.
+
+Traditional vector stores retrieve. MnemoCore **thinks**. It is built on the mathematical framework of **Binary Hyperdimensional Computing (HDC)** and **Vector Symbolic Architectures (VSA)**, principles rooted in Pentti Kanerva's landmark 2009 theory of cognitive computing. Every memory is encoded as a **16,384-dimensional binary holographic vector** — a format that is simultaneously compact (2,048 bytes), noise-tolerant (Hamming geometry), and algebraically rich (XOR binding, majority bundling, circular permutation).
+
+At its core lives the **Holographic Active Inference Memory (HAIM) Engine** — a system that does not merely answer queries, but:
+
+- **Evaluates** the epistemic novelty of every incoming memory before deciding to store it
+- **Dreams** — strengthening synaptic connections between related memories during idle cycles
+- **Reasons by analogy** — if `king:man :: ?:woman`, the VSA soul computes `queen`
+- **Self-organizes** into tiered storage based on biologically-inspired Long-Term Potentiation (LTP)
+- **Scales** from a single process to distributed nodes targeting 1B+ memories
+
+Phase 4.x introduces cognitive enhancements including contextual masking, reliability feedback loops, semantic consolidation, gap detection/filling, temporal recall (episodic chaining + chrono-weighted query), a Subconscious Daemon with LLM-powered dream synthesis, and a full dependency-injection container pattern for clean modularity.

+
+## Core Technology: Binary HDV & VSA
+
+MnemoCore's mathematical foundation is **Hyperdimensional Computing** — a computing paradigm that encodes information in very high-dimensional binary vectors (HDVs), enabling noise-tolerant, distributed, and algebraically composable representations.
+
+### The Vector Space
+
+Every piece of information — a word, a sentence, a concept, a goal — is encoded as a **16,384-dimensional binary vector**:
+
+```
+Dimension D = 16,384 bits = 2,048 bytes per vector
+Storage: packed as numpy uint8 arrays
+Similarity: Hamming distance (popcount of XOR result)
+Random pair: ~50% similarity (orthogonality by probability)
+```
+
+At this dimensionality, two random vectors will differ in ~50% of bits. This near-orthogonality is the foundation of the system's expressive power — related concepts cluster together while unrelated ones remain maximally distant.
+
+### VSA Algebra
+
+Four primitive operations make the entire system work:
+
+#### Binding — XOR `⊕`
+Creates an association between two concepts. Crucially, the result is **dissimilar to both inputs** (appears as noise), making it a true compositional operation.
+
+```python
+# Bind content to its context
+bound = content_vec.xor_bind(context_vec) # content ⊕ context
+
+# Self-inverse: unbind by re-binding
+recovered = bound.xor_bind(context_vec) # ≈ content (XOR cancels)
+```
+
+Key mathematical properties:
+- **Self-inverse**: `A ⊕ A = 0` (XOR cancels itself)
+- **Commutative**: `A ⊕ B = B ⊕ A`
+- **Distance-preserving**: `hamming(A⊕C, B⊕C) = hamming(A, B)`
+
+#### Bundling — Majority Vote
+Creates a **prototype** that is similar to all inputs. This is how multiple memories combine into a concept.
+
+```python
+from mnemocore.core.binary_hdv import majority_bundle
+
+# Create semantic prototype from related memories
+concept = majority_bundle([vec_a, vec_b, vec_c, vec_d]) # similar to all inputs
+```
+
+#### Permutation — Circular Shift
+Encodes **sequence and roles** without separate positional embeddings.
+
+```python
+# Positional encoding: token at position i
+positioned = token_vec.permute(shift=i) # circular bit-shift
+
+# Encode "hello world" with order information
+hello_positioned = encoder.get_token_vector("hello").permute(0)
+world_positioned = encoder.get_token_vector("world").permute(1)
+sentence_vec = majority_bundle([hello_positioned, world_positioned])
+```
+
+#### Similarity — Hamming Distance
+Fast comparison using vectorized popcount over XOR results:
+
+```python
+# Normalized similarity: 1.0 = identical, 0.5 = unrelated
+sim = vec_a.similarity(vec_b) # 1.0 - hamming(a, b) / D
+
+# Batch nearest-neighbor search (no Python loops)
+distances = batch_hamming_distance(query, database_matrix)
+```
+
+### Text Encoding Pipeline
+
+The `TextEncoder` converts natural language to HDVs using a token-position binding scheme:
+
+```
+"Python TypeError" →
+ token_hdv("python") ⊕ permute(0) = positioned_0
+ token_hdv("typeerror") ⊕ permute(1) = positioned_1
+ majority_bundle([positioned_0, positioned_1]) = final_hdv
+```
+
+Token vectors are **deterministic** — seeded via SHAKE-256 hash — meaning the same word always produces the same base vector, enabling cross-session consistency without a vocabulary file.
+
+---
+
+## The Memory Lifecycle
+
+Every memory passes through a defined lifecycle from ingestion to long-term storage:
+
+```
+Incoming Content
+ │
+ ▼
+ ┌─────────────┐
+ │ TextEncoder │ → 16,384-dim binary HDV
+ └──────┬──────┘
+ │
+ ▼
+ ┌──────────────────┐
+ │ Context Binding │ → XOR bind with goal_context if present
+ │ (XOR) │ bound_vec = content ⊕ context
+ └──────┬───────────┘
+ │
+ ▼
+ ┌──────────────────┐
+ │ EIG Evaluation │ → Epistemic Information Gain
+ │ (Novelty Check) │ eig = normalized_distance(vec, context_vec)
+ └──────┬───────────┘ tag "epistemic_high" if eig > threshold
+ │
+ ▼
+ ┌─────────────────┐
+ │ MemoryNode │ → id, hdv, content, metadata
+ │ Creation │ ltp_strength = I × log(1+A) × e^(-λT)
+ └──────┬──────────┘
+ │
+ ▼
+ ┌─────────────────┐
+ │ HOT Tier │ → In-memory dict (max 2000 nodes)
+ │ (RAM) │ LTP eviction: low-LTP nodes → WARM
+ └──────┬──────────┘
+ │ (background)
+ ▼
+ ┌─────────────────┐
+ │ Subconscious │ → Dream cycle fires
+ │ Dream Loop │ Query similar memories
+ └──────┬──────────┘ Strengthen synapses (Hebbian)
+ │
+ ▼
+ ┌─────────────────┐
+ │ WARM Tier │ → Redis-backed persistence
+ │ (Redis/mmap) │ async dual-write + pub/sub events
+ └──────┬──────────┘
+ │ (scheduled, nightly)
+ ▼
+ ┌─────────────────┐
+ │ COLD Tier │ → Qdrant / Disk / S3
+ │ (Archival) │ ANN search, long-term persistence
+ └─────────────────┘
+```
+
+### Long-Term Potentiation (LTP)
+
+Memories are not equal. Importance is computed dynamically using a biologically-inspired LTP formula:
+
+```
+S = I × log(1 + A) × e^(-λ × T)
+
+Where:
+ S = LTP strength (determines tier placement)
+ I = Importance (derived from epistemic + pragmatic value)
+ A = Access count (frequency of retrieval)
+ λ = Decay lambda (configurable, default ~0.01)
+ T = Age in days
+```
+
+Memories with high LTP remain in HOT tier. Those that decay are automatically promoted to WARM, then COLD — mirroring how biological memory consolidates from working memory to long-term storage.
+
+### Synaptic Connections
+
+Memories are linked by `SynapticConnection` objects that implement Hebbian learning: *"neurons that fire together, wire together."*
+
+Every time two memories are co-retrieved (via the background dream loop or explicit binding), their synaptic strength increases. During query time, synaptic spreading amplifies scores of connected memories even when they do not directly match the query vector — enabling **associative recall**.
+
+```python
+# Explicit synapse creation
+engine.bind_memories(id_a, id_b, success=True)
+
+# Associative spreading: query top seeds spread activation to neighbors
+# neighbor_score += seed_score × synapse_strength × 0.3
+```
+
+---
+
+## Tiered Storage: HOT / WARM / COLD
+
+| Tier | Backend | Capacity | Latency | Eviction Trigger |
+|------|---------|----------|---------|------------------|
+| 🔥 **HOT** | Python dict (RAM) | 2,000 nodes | < 1ms | LTP < threshold |
+| 🌡 **WARM** | Redis + mmap | 100,000 nodes | < 10ms | Age + low access |
+| ❄️ **COLD** | Qdrant / Disk / S3 | Unlimited | < 100ms | Manual / scheduled |
+
+Promotion is automatic: accessing a WARM or COLD memory re-promotes it to HOT based on recalculated LTP. Eviction is LRU-weighted by LTP strength — the most biologically active memories always stay hot.
+
+---
+
+## Phase 4.0 Cognitive Enhancements
+
+MnemoCore Phase 4.0 introduces five architectural enhancements that elevate the system from **data retrieval** to **cognitive reasoning**. Full implementation specifications are in [`COGNITIVE_ENHANCEMENTS.md`](COGNITIVE_ENHANCEMENTS.md).
+
+---
+
+### 1. Contextual Query Masking *(XOR Attention)*
+
+**Problem**: Large multi-project deployments suffer from cross-context interference. A query for `"Python error handling"` returns memories from all projects equally, diluting precision.
+
+**Solution**: Bidirectional XOR context binding — apply the same context vector at both **storage** and **query** time:
+
+```
+Store: bound_vec = content ⊕ context_vec
+Query: masked_query = query ⊕ context_vec
+
+Result: (content ⊕ C) · (query ⊕ C) ≈ content · query
+ (context cancels, cross-project noise is suppressed)
+```
+
+```python
+# Store memories in a project context
+engine.store("API rate limiting logic", goal_id="ProjectAlpha")
+engine.store("Garden watering schedule", goal_id="HomeProject")
+
+# Query with context mask — only ProjectAlpha memories surface
+results = engine.query("API logic", top_k=5, context="ProjectAlpha")
+```
+
+**Expected impact**: +50–80% query precision (P@5) in multi-project deployments.
+
+---
+
+### 2. Reliability Feedback Loop *(Self-Correcting Memory)*
+
+**Problem**: Wrong or outdated memories persist with the same retrieval weight as correct ones. The system has no mechanism to learn from its own mistakes.
+
+**Solution**: Bayesian reliability scoring with real-world outcome feedback:
+
+```
+reliability = (successes + 1) / (successes + failures + 2) # Laplace smoothing
+
+LTP_enhanced = I × log(1+A) × e^(-λT) × reliability
+```
+
+```python
+# After using a retrieved memory:
+engine.provide_feedback(memory_id, outcome=True) # Worked → boost reliability
+engine.provide_feedback(memory_id, outcome=False) # Failed → reduce reliability
+
+# System auto-tags consistently wrong memories as "unreliable"
+# and verified memories (>5 successes, >0.8 score) as "verified"
+```
+
+The system converges toward **high-confidence knowledge** — memories that have demonstrably worked in practice rank above theoretically similar but unproven ones.
+
+---
+
+### 3. Semantic Memory Consolidation *(Dream-Phase Synthesis)*
+
+**Problem**: Episodic memory grows without bound. 1,000 memories about `"Python TypeError"` are semantically equivalent but consume 2MB of vector space and slow down linear scan queries.
+
+**Solution**: Nightly `ConsolidationWorker` clusters similar WARM tier memories and replaces them with a **semantic anchor** — a majority-bundled prototype:
+
+```
+BEFORE consolidation:
+ mem_001: "Python TypeError in line 45" (2KB vector)
+ mem_002: "TypeError calling function" (2KB vector)
+ ... ×100 similar memories (200KB total)
+
+AFTER consolidation:
+ anchor_001: "Semantic pattern: python typeerror function"
+ metadata: {source_count: 100, confidence: 0.94}
+ hdv: majority_bundle([mem_001.hdv, ..., mem_100.hdv]) (2KB)
+```
+
+```python
+# Manual trigger (runs automatically at 3 AM)
+stats = engine.trigger_consolidation()
+# → {"abstractions_created": 12, "memories_consolidated": 847}
+
+# Via API (admin endpoint)
+POST /admin/consolidate
+```
+
+**Expected impact**: 70–90% memory footprint reduction, 10x query speedup at scale.
+
+---
+
+### 4. Auto-Associative Cleanup Loop *(Vector Immunology)*
+
+**Problem**: Holographic vectors degrade over time through repeated XOR operations, noise accumulation, and long-term storage drift. After months of operation, retrieved vectors become "blurry" and similarity scores fall.
+
+**Solution**: Iterative attractor dynamics — when a retrieved vector appears noisy, snap it to the nearest stable concept in a **codebook** of high-confidence prototypes:
+
+```
+noisy_vec → find K nearest in codebook
+ → majority_bundle(K neighbors)
+ → check convergence (Hamming distance < 5%)
+ → iterate until converged or max iterations reached
+```
+
+```python
+# Cleanup runs automatically on retrieval when noise > 15%
+node = engine.get_memory(memory_id, auto_cleanup=True)
+# node.metadata["cleaned"] = True (if cleanup was triggered)
+# node.metadata["cleanup_iterations"] = 3
+
+# Codebook is auto-populated from most-accessed, high-reliability memories
+```
+
+**Expected impact**: Maintain >95% similarity fidelity even after years of operation.
+
+---
+
+### 5. Knowledge Gap Detection *(Proactive Curiosity)*
+
+**Problem**: The system is entirely reactive — it answers queries but never identifies what it *doesn't know*. True cognitive autonomy requires self-directed learning.
+
+**Solution**: Temporal co-occurrence analysis — detect concepts that are frequently accessed **close in time** but have **no synaptic connection**, flagging them as knowledge gaps:
+
+```python
+# Automatically runs hourly
+gaps = engine.detect_knowledge_gaps(time_window_seconds=300)
+
+# Returns structured insight:
+# [
+# {
+# "concept_a": "Python asyncio event loop",
+# "concept_b": "FastAPI dependency injection",
+# "suggested_query": "How does asyncio relate to FastAPI dependency injection?",
+# "co_occurrence_count": 4
+# }
+# ]
+
+# Query endpoint
+GET /insights/gaps?lookback_hours=24
+
+# Fill gap manually (or via LLM agent)
+POST /insights/fill-gap
+{"concept_a_id": "mem_xxx", "concept_b_id": "mem_yyy",
+ "explanation": "FastAPI uses asyncio's event loop internally..."}
+```
+
+The system becomes capable of **saying what it doesn't understand** and requesting clarification — the first step toward genuine cognitive autonomy.
+
+---
+
+## Phase 4.4–4.5: Subconscious Daemon & LLM Integration
+
+### Subconscious Daemon *(Autonomous Background Mind)*
+
+Phase 4.4 introduced `SubconsciousAI` — a worker that fires during idle cycles and calls an external LLM to generate **synthetic dream memories**: structured insights derived by reasoning over existing memory clusters, rather than through direct observation.
+
+Phase 4.5 hardened this into a full `SubconsciousDaemon` — an independently managed asyncio process that orchestrates dream cycles, consolidation scheduling, and subconscious queue processing:
+
+```python
+# The daemon is started automatically when the API starts up.
+# It coordinates:
+# - Dream synthesis: SubconsciousAI → LLM → synthetic insights stored back
+# - Consolidation scheduling: ConsolidationWorker fired on a configurable interval
+# - Subconscious queue: novelty detection from Redis pub/sub stream
+```
+
+Configure in `config.yaml`:
+
+```yaml
+haim:
+ subconscious_ai:
+ enabled: true
+ api_url: "https://api.openai.com/v1/chat/completions" # or Anthropic
+ model: "gpt-4o-mini"
+ # api_key: set via SUBCONSCIOUS_AI_API_KEY env var
+ dream_interval_seconds: 300
+ batch_size: 5
+```
+
+### Dependency Injection Container
+
+All major services (TierManager, AsyncRedisStorage, QdrantStore, SubconsciousAI, etc.) are now wired through `src/mnemocore/core/container.py`. This eliminates global singleton state and makes every subsystem testable in isolation:
+
+```python
+from mnemocore.core.container import build_container
+
+container = build_container(config)
+engine = container.engine()
+tier_mgr = container.tier_manager()
+```
+
+### LLM Agent Integration
+
+`src/mnemocore/llm_integration.py` provides a high-level interface for attaching MnemoCore to any OpenAI/Anthropic-style LLM agent loop:
+
+```python
+from mnemocore.llm_integration import MnemoCoreAgent
+
+agent = MnemoCoreAgent(engine)
+
+# Store agent observations
+agent.observe("User prefers concise answers over verbose ones")
+
+# Recall relevant context before a response
+context = agent.recall("user preference", top_k=3)
+```
+
+---
+
+## API Reference
+
+### Authentication
+
+All endpoints require an API key via the `X-API-Key` header:
+
+```bash
+export HAIM_API_KEY="your-secure-key"
+curl -H "X-API-Key: $HAIM_API_KEY" ...

+
+## Python Library Usage
+
+### Basic Store and Query
+
+```python
+from mnemocore.core.engine import HAIMEngine
+
+engine = HAIMEngine(persist_path="./data/memory.jsonl")
+
+# Store memories
+engine.store("Python generators are lazy iterators", metadata={"topic": "python"})
+engine.store("Use 'yield' to create generator functions", metadata={"topic": "python"})
+engine.store("Redis XADD appends to a stream", goal_id="infrastructure")
+
+# Query (global)
+results = engine.query("How do Python generators work?", top_k=3)
+for mem_id, score in results:
+ mem = engine.get_memory(mem_id)
+ print(f"[{score:.3f}] {mem.content}")
+
+# Query with context masking
+results = engine.query("data streams", top_k=5, context="infrastructure")
+
+engine.close()
+```
+
+### Analogical Reasoning
+
+```python
+# Define concepts
+engine.define_concept("king", {"gender": "man", "role": "ruler"})
+engine.define_concept("queen", {"gender": "woman", "role": "ruler"})
+engine.define_concept("man", {"gender": "man"})
+
+# VSA analogy: king:man :: ?:woman → queen
+result = engine.reason_by_analogy(
+ src="king", val="man", tgt="woman"
+)
+print(result) # [("queen", 0.934), ...]
+```
+
+### Working with the Binary HDV Layer Directly
+
+```python
+from mnemocore.core.binary_hdv import BinaryHDV, TextEncoder, majority_bundle
+
+encoder = TextEncoder(dimension=16384)
+
+# Encode text
+python_vec = encoder.encode("Python programming")
+fastapi_vec = encoder.encode("FastAPI framework")
+error_vec = encoder.encode("error handling")
+
+# Bind concept to role
+python_in_fastapi = python_vec.xor_bind(fastapi_vec)
+
+# Bundle multiple concepts into prototype
+web_dev_prototype = majority_bundle([python_vec, fastapi_vec, error_vec])
+
+# Similarity
+print(python_vec.similarity(web_dev_prototype)) # High (part of bundle)
+print(python_vec.similarity(error_vec)) # ~0.5 (unrelated)
+
+# Batch nearest-neighbor search
+from mnemocore.core.binary_hdv import batch_hamming_distance
+import numpy as np
+
+database = np.stack([v.data for v in [python_vec, fastapi_vec, error_vec]])
+distances = batch_hamming_distance(python_vec, database)
+```
+
+### Reliability Feedback Loop
+
+```python
+mem_id = engine.store("Always use asyncio.Lock() in async code, not threading.Lock()")
+results = engine.query("async locking")
+
+# It works — report success
+engine.provide_feedback(mem_id, outcome=True, comment="Solved deadlock issue")
+
+# Over time, high-reliability memories get 'verified' tag
+# and are ranked above unproven ones in future queries
+```
+
+### Semantic Consolidation
+
+```python
+stats = engine.trigger_consolidation()
+print(f"Created {stats['abstractions_created']} semantic anchors")
+print(f"Consolidated {stats['memories_consolidated']} episodic memories")
+
+# Automatic: runs every night at 3 AM via background asyncio task
+```
+
+---
+
+## Installation
+
+### Prerequisites
+
+- **Python 3.10+**
+- **Redis 6+** — Required for WARM tier and async event streaming
+- **Qdrant** *(optional)* — For COLD tier at billion-scale
+- **Docker** *(recommended)* — For Redis and Qdrant services
+
+### Quick Start
+
+```bash
+# 1. Clone
+git clone https://github.com/RobinALG87/MnemoCore-Infrastructure-for-Persistent-Cognitive-Memory.git
+cd MnemoCore-Infrastructure-for-Persistent-Cognitive-Memory
+
+# 2. Create virtual environment
+python -m venv .venv
+.\.venv\Scripts\activate # Windows (PowerShell)
+# source .venv/bin/activate # Linux / macOS
+
+# 3. Install (recommended — uses pyproject.toml as canonical source)
+pip install -e .
+
+# Or install runtime deps only (Docker / legacy):
+# pip install -r requirements.txt
+
+# To include dev tools (pytest, mypy, black, etc.):
+pip install -e ".[dev]"
+
+# 4. Start Redis
+docker run -d -p 6379:6379 redis:7.2-alpine
+
+# 5. Set API key (never hardcode — use env var or .env file)
+# Windows PowerShell:
+$env:HAIM_API_KEY = "your-secure-key-here"
+# Linux / macOS:
+# export HAIM_API_KEY="your-secure-key-here"
+
+# 6. Start the API
+uvicorn mnemocore.api.main:app --host 0.0.0.0 --port 8100
+```
+
+The API is now live at `http://localhost:8100`. Visit `http://localhost:8100/docs` for the interactive Swagger UI.
+
+### Using the .env file
+
+Copy the provided template and fill in your values — the API and docker-compose both pick it up automatically:
+
+```bash
+cp .env.example .env
+# Edit .env and set HAIM_API_KEY, REDIS_URL, etc.
+```
+
+> **Note:** `.env` is listed in `.gitignore` and must never be committed. Only `.env.example` (with placeholder values) belongs in version control.
+
+### Full Stack with Docker Compose
+
+```bash
+# Requires .env with HAIM_API_KEY set
+docker compose up -d
+```
+
+This starts MnemoCore, Redis 7.2, and Qdrant in one command.
+
+### With Qdrant (Phase 4.x Scale)
+
+```bash
+# Start Qdrant alongside Redis
+docker run -d -p 6333:6333 qdrant/qdrant
+
+# Enable in config.yaml
+qdrant:
+ enabled: true
+ host: localhost
+ port: 6333
+```
+
+---
+
+## Configuration
+
+All configuration lives in `config.yaml`. Sensitive values can be overridden with environment variables — the config loader looks for `HAIM_`-prefixed vars and also honours per-service overrides like `HAIM_API_KEY`, `REDIS_PASSWORD`, `QDRANT_API_KEY`, `HAIM_CORS_ORIGINS`, and `SUBCONSCIOUS_AI_API_KEY`.
+

+
+### Security Note
+
+MnemoCore requires an explicit API key. There is no default fallback key in production builds.
+
+```bash
+# Generate a cryptographically secure key:
+python -c "import secrets; print(secrets.token_urlsafe(32))"
+
+# Set it (never commit this value):
+export HAIM_API_KEY=""
+```
+
+---
+
+## MCP Server Integration
+
+MnemoCore exposes a **Model Context Protocol (MCP)** server, enabling direct integration with Claude, GPT-4, and any MCP-compatible agent framework.
+
+### Setup
+
+```bash
+# Start API first
+uvicorn mnemocore.api.main:app --host 0.0.0.0 --port 8100
+
+# Configure MCP in config.yaml
+haim:
+ mcp:
+ enabled: true
+ transport: "stdio" # or "sse" for streaming
+
+# Run MCP server
+python -m mnemocore.mcp.server
+```
+
+### Claude Desktop Configuration
+
+Add to your Claude Desktop `config.json`:
+
+```json
+{
+ "mcpServers": {
+ "mnemocore": {
+ "command": "python",
+ "args": ["-m", "mnemocore.mcp.server"],
+ "env": {
+ "HAIM_API_KEY": "your-key",
+ "HAIM_BASE_URL": "http://localhost:8100"
+ }
+ }
+ }
+}
+```
+
+Once connected, the agent can:
+- `store_memory(content, context)` — persist learned information
+- `query_memory(query, context, top_k)` — recall relevant memories
+- `provide_feedback(memory_id, outcome)` — signal what worked
+- `get_knowledge_gaps()` — surface what it doesn't understand
+
+---
+
+## Observability
+
+MnemoCore ships with built-in Prometheus metrics and structured logging.
+
+### Prometheus Metrics
+
+Available at `GET /metrics`:
+
+| Metric | Description |
+|--------|-------------|
+| `haim_api_request_count` | Total requests by endpoint and status |
+| `haim_api_request_latency_seconds` | Request latency histogram |
+| `haim_storage_operation_count` | Store/query/delete operations |
+| `haim_hot_tier_size` | Current HOT tier memory count |
+| `haim_synapse_count` | Active synaptic connections |
+
+### Grafana Dashboard
+
+A sample Grafana dashboard config is available at `grafana-dashboard.json` in the repository root. Import it directly into Grafana via **Dashboards → Import → Upload JSON file**.
+
+### Structured Logging
+
+All components use structured Python logging with contextual fields:
+
+```

+
+---
+
+## Contributing
+
+MnemoCore is an active research project. Contributions are welcome — especially:
+
+- **Performance**: CUDA kernels, FAISS integration, async refactoring
+- **Algorithms**: Better clustering for consolidation, improved EIG formulas
+- **Integrations**: New storage backends, LLM connectors
+- **Tests**: Coverage for edge cases, property-based testing
+
+### Process
+
+```bash
+# Fork and clone
+git checkout -b feature/your-feature-name
+
+# Make changes, ensure tests pass
+pytest
+
+# Commit with semantic message
+git commit -m "feat(consolidation): add LLM-powered prototype labeling"
+
+# Open PR — describe the what, why, and performance impact
+```
+
+Please follow the implementation patterns established in `docs/ARCHITECTURE.md` and `docs/ROADMAP.md` for architectural guidance, and review `CHANGELOG.md` to understand what has already landed.

+# Refactoring TODO
+
+Status för kodoptimering inför kommande funktionalitet.
+
+---
+
+## Hög Prioritet
+
+### 1. Konsolidera HDV-implementation
+**Status:** ✅ Completed (2026-02-18)
+
+**Problem:**
+- Dubbel implementation: `src/core/hdv.py` (float) + `src/core/binary_hdv.py` (binary)
+- Skapar branch-logik genom hela koden
+- Float HDV är legacy och bör depreceras
+
+**Åtgärder genomförda:**
+- `src/core/hdv.py` - Markerad som DEPRECATED med varning
+- `src/core/__init__.py` - Exporterar nu BinaryHDV först
+- `src/core/node.py` - Använder endast BinaryHDV
+- `src/core/holographic.py` - Konverterad till BinaryHDV med XOR-binding
+- `src/core/router.py` - Tog bort HDV-branching
+- `src/core/engine.py` - Tog bort Union-typer och branching
+- `src/core/tier_manager.py` - Standardiserade på BinaryHDV
+
+---
+
+### 2. Ofullständiga features
+**Status:** Pending
+
+**Problem:**
+- Flera TODOs i produktionskod som lämnats oimplementerade
+
+**Filer:**
+- `src/llm_integration.py`
+
+**TODOs:**
+```
+Line 56: # TODO: Call Gemini 3 Pro via OpenClaw API
+Line 106: # TODO: superposition_query() not implemented in HAIMEngine
+Line 131: # TODO: Call Gemini 3 Pro
+Line 301: # TODO: Implement concept-to-memory-ID mapping
+Line 320: # TODO: orchestrate_orch_or() not implemented
+```
+
+**Åtgärd:**
+- Implementera funktionerna
+- Eller ta bort dödkod
+
+---
+
+### 3. Standardisera felhantering
+**Status:** Pending
+
+**Problem:**
+- Vissa funktioner returnerar `None` vid fel
+- Andra kastar exceptions
+- Svårt att förutse felbeteende
+
+**Åtgärd:**
+- Definiera domän-specifika exceptions:
+ - `MemoryNotFoundError`
+ - `StorageError`
+ - `EncodingError`
+ - `ConsolidationError`
+- Skapa `src/core/exceptions.py`
+- Uppdatera alla moduler att använda konsistent felhantering
+
+---
+
+## Medelprioritet
+
+### 4. Minska Singleton-användning
+**Status:** 📋 Roadmap
+
+**Problem:**
+- `AsyncRedisStorage.get_instance()`
+- `QdrantStore.get_instance()`
+- Försvårar testning
+
+**Åtgärd:**
+- Inför Dependency Injection
+- Passa beroenden via konstruktor
+
+**Komplexitet:** Hög - Kräver genomgripande ändringar av instansiering
+
+---
+
+### 5. Bryt isär stora funktioner
+**Status:** 📋 Roadmap
+
+**Problem:**
+- `engine.py:store()` - 76 rader
+- `tier_manager.py:consolidate_warm_to_cold()` - 48 rader
+
+**Åtgärd:**
+- Extrahera till mindre, testbara enheter
+
+**Komplexitet:** Hög - Refaktorering av kärnlogik
+
+---
+
+### 6. Konsolidera Circuit Breakers
+**Status:** ✅ Completed (2026-02-18)
+
+**Problem:**
+- `src/core/resilience.py` - pybreaker implementation
+- `src/core/reliability.py` - Native implementation
+- Dubbel implementation
+
+**Åtgärder genomförda:**
+- `src/core/reliability.py` - Nu primär modul med pre-konfigurerade instanser
+- `src/core/resilience.py` - Markerad som DEPRECATED
+- `src/core/qdrant_store.py` - Uppdaterad till reliability
+- `src/api/main.py` - Uppdaterad till reliability, tog bort pybreaker-beroende
+
+---
+
+### 7. Centralisera hårkodade sökvägar
+**Status:** ✅ Completed (2026-02-18)
+
+**Problem:**
+- `"./data"` fanns hårdkodat på flera ställen
+
+**Åtgärder genomförda:**
+- `src/core/holographic.py` - Använder nu `config.paths.data_dir` som default
+- Alla sökvägar centraliserade i `config.yaml` och `HAIMConfig`
+
+---
+
+### 8. Standardisera import-stil
+**Status:** ✅ Verified (2026-02-18)
+
+**Problem:**
+- Blandning av relativa och absoluta imports
+- Till och med inom samma fil
+
+**Analys:**
+- `src/core/` använder konsekvent relativa imports (`.module`)
+- Övriga moduler använder absoluta imports (`src.core.module`)
+- Inga filer har blandad stil
+
+**Slutsats:**
+Import-stilen följer redan rekommenderad Python-praxis. Ingen åtgärd behövs.
+
+---
+
+## Låg prioritet
+
+### 9. Rensa debug-filer
+- Ta bort eller flytta `debug_*.py`
+- Konsolidera test-helpers
+
+### 10. Standardisera logging
+- Välj ett framework (loguru rekommenderas)
+- Ta bort ad-hoc print-statements
+
+### 11. Förbättra typsäkerhet
+- Lägg till mypy i CI
+- Komplettera type hints
+- Använd `TypedDict` för komplexa dict-returns
+
+---
+
+## Förbättra testtäckning
+
+```bash
+pytest --cov=src --cov-report=html
+```
+
+Kör för att identifiera luckor i testtäckningen.
+
+---
+
+## Fil-prioriteringslista
+
+| Prioritet | Fil | Anledning |
+|-----------|-----|-----------|
+| 1 | `src/core/engine.py` | Kärnlogik, HDV dual-mode |
+| 2 | `src/core/tier_manager.py` | Stora funktioner, lagringskomplexitet |
+| 3 | `src/llm_integration.py` | Flera oimplementerade TODOs |
+| 4 | `src/core/resilience.py` | Duplikat circuit breaker |
+| 5 | `src/core/binary_hdv.py` | Överväg extrahering till separat paket |
+
+---
+
+## Framsteg
+
+- [x] Punkt 1: HDV-konsolidering ✅
+- [ ] Punkt 2: Ofullständiga features
+- [ ] Punkt 3: Felhantering
+- [ ] Punkt 4: Singleton-reduktion 📋 Roadmap
+- [ ] Punkt 5: Stora funktioner 📋 Roadmap
+- [x] Punkt 6: Circuit breakers ✅
+- [x] Punkt 7: Hårkodade sökvägar ✅
+- [x] Punkt 8: Import-stil ✅ (redan konsekvent)
+
+---
+
+## Roadmap (Framtida refaktorering)
+
+Dessa punkter kräver mer omfattande ändringar och bör planeras in senare:
+
+| Punkt | Beskrivning | Komplexitet |
+|-------|-------------|-------------|
+| 4 | Minska Singleton-användning, inför DI | Hög |
+| 5 | Bryt isär stora funktioner i engine/tier_manager | Hög |

+## 🔧 Code TODOs (Known Limitations)
+
+These are documented gaps that can ship as "Phase 4 roadmap" items:
+
+### 1. `src/core/tier_manager.py:338`
+```python
+pass # TODO: Implement full consolidation with Qdrant
+```
+**Impact:** Warm→Cold tier consolidation limited
+**Workaround:** Hot→Warm works, Cold is filesystem-based
+**Fix:** Implement Qdrant batch scroll API for full archival
+
+### 2. `src/core/engine.py:192`
+```python
+# TODO: Phase 3.5 Qdrant search for WARM/COLD
+```
+**Impact:** Query only searches HOT tier currently
+**Workaround:** Promote memories before querying
+**Fix:** Add async Qdrant similarity search in query()
+
+### 3. `src/llm_integration.py:55-57, 128-129`
+```python
+# TODO: Call Gemini 3 Pro via OpenClaw API
+reconstruction = "TODO: Call Gemini 3 Pro"
+```
+**Impact:** LLM reconstruction not functional
+**Workaround:** Raw vector similarity works
+**Fix:** Implement LLM client or make it pluggable
+
+### 4. `src/nightlab/engine.py:339`
+```python
+# TODO: Notion API integration
+```
+**Impact:** Session documentation not auto-pushed
+**Workaround:** Written to local markdown files

+# MnemoCore API Reference (Beta)
+
+## Beta Notice
+
+API contracts may change during beta without backward compatibility guarantees.
+Use pinned commits if you need reproducibility.
+
+## Base URL
+
+Default local API URL:
+- `http://localhost:8100`
+
+## Endpoints
+
+### `GET /`
+Basic service status.
+
+### `GET /health`
+Returns health status, Redis connectivity, and engine stats.
+
+### `POST /store`
+Store a memory.
+
+Request body:
+```json
+{
+ "content": "string",
+ "metadata": {"key": "value"},
+ "agent_id": "optional-string",
+ "ttl": 3600
+}
+```
+
+### `POST /query`
+Query semantic memory.
+
+Request body:
+```json
+{
+ "query": "string",
+ "top_k": 5,
+ "agent_id": "optional-string"
+}
+```
+
+### `GET /memory/{memory_id}`
+Fetch a memory by ID (Redis-first, engine fallback).
+
+### `DELETE /memory/{memory_id}`
+Delete a memory by ID.
+
+### `POST /concept`
+Define a concept for conceptual memory operations.
+
+### `POST /analogy`
+Run analogy inference.
+
+### `GET /stats`
+Return engine statistics.
+
+### `GET /metrics`
+Prometheus metrics endpoint.
+
+## Example Requests
+
+Store:
+```bash
+curl -X POST http://localhost:8100/store \
+ -H "Content-Type: application/json" \
+ -d '{"content":"Birds can migrate long distances"}'
+```
+
+Query:
+```bash
+curl -X POST http://localhost:8100/query \
+ -H "Content-Type: application/json" \
+ -d '{"query":"animal migration","top_k":3}'
+```
+
+## Error Behavior
+
+- `404` for missing memory IDs.
+- In degraded infrastructure modes, API may still return successful core operations while external storage writes fail.
+
+## Compatibility Guidance
+
+During beta, treat responses as evolving contracts:
+- Parse defensively.
+- Avoid rigid coupling to optional fields.
+- Revalidate after version upgrades.

+# MnemoCore Architecture (Beta)
+
+## Beta Context
+
+This document describes the current implementation direction in beta.
+It is not a guarantee of final architecture, performance, or feature completeness.
+
+## Core Components
+
+- `src/core/engine.py`: Main orchestration for memory storage, encoding, query, and synaptic augmentation.
+- `src/core/binary_hdv.py`: Binary hyperdimensional vector operations.
+- `src/core/tier_manager.py`: HOT/WARM/COLD placement and movement logic.
+- `src/core/config.py`: Typed config loading from YAML + env overrides.
+- `src/core/async_storage.py`: Async Redis metadata operations.
+- `src/api/main.py`: FastAPI interface.
+
+## Memory Model
+
+MnemoCore represents memory as high-dimensional vectors and metadata-rich nodes:
+
+1. Encode input text into vector representation.
+2. Store node in HOT tier initially.
+3. Apply reinforcement/decay dynamics (LTP-related logic).
+4. Move between tiers based on thresholds and access patterns.
+
+## Tiering Model
+
+- **HOT**: In-memory dictionary for fastest access.
+- **WARM**: Qdrant-backed where available; filesystem fallback when unavailable.
+- **COLD**: Filesystem archival path for long-lived storage.
+
+## Query Flow (Current Beta)
+
+Current query behavior prioritizes HOT tier recall and synaptic score augmentation.
+Cross-tier retrieval is still evolving and should be treated as beta behavior.
+
+## Async + External Services
+
+- Redis is used for async metadata and event stream operations.
+- API startup checks Redis health and can operate in degraded mode.
+- Qdrant usage is enabled through tier manager and can fall back to local files.
+
+## Observability
+
+- Prometheus metrics endpoint mounted at `/metrics` in API server.
+- Logging behavior controlled through config.
+
+## Practical Limitations
+
+- Some roadmap functionality remains TODO-marked in code.
+- Interface contracts may change across beta releases.
+- Performance can vary significantly by hardware and data profile.
+
+For active limitations and next work items, see `docs/ROADMAP.md`.

+# MnemoCore Beta Policy
+
+## Status
+
+MnemoCore is published as a **beta / development preview**.
+
+This means:
+- No production readiness claim.
+- No availability, performance, or compatibility guarantees.
+- No commitment to stable APIs between beta releases.
+- Experimental behavior is expected.
+
+## No Promises / No Warranty
+
+MnemoCore is provided "as is" under the MIT license.
+
+- We do not guarantee correctness for any specific use case.
+- We do not guarantee fitness for business-critical workloads.
+- We do not guarantee long-term support for current interfaces.
+
+Always validate outputs independently before operational use.
+
+## Recommended Usage During Beta
+
+- Use in sandboxes, R&D, and controlled evaluation environments.
+- Pin commit hashes for reproducibility.
+- Treat data formats and endpoint contracts as potentially changing.
+- Keep backups of data and configuration before upgrading.
+
+## Production Adoption Guidance
+
+Before production usage in your own environment, you should perform:
+- Independent reliability testing.
+- Security and privacy review.
+- Capacity and failure-mode validation.
+- Rollback planning and observability setup.
+
+## Communication Principle
+
+All public communication should describe MnemoCore as:
+- Experimental,
+- Beta,
+- Subject to change,
+- Without guarantees or promises.
+
+## Contact
+
+- General contact: Robin@veristatesystems.com
+- Security disclosure: Robin@veristatesystems.com

+# MnemoCore MCP Implementation Plan (Beta)
+
+## Goal
+
+Expose MnemoCore capabilities through a Model Context Protocol (MCP) server so external LLM agents can safely store, query, and inspect memory with predictable contracts.
+
+## Scope (Phase 1)
+
+### In Scope
+
+- MCP server process for local/dev use.
+- Read/write memory tools mapped to existing engine/API capabilities.
+- Basic auth + request limits aligned with existing API policy.
+- Test coverage for MCP tool contracts and degraded dependencies.
+
+### Out of Scope (Phase 1)
+
+- Multi-tenant policy engine.
+- Full distributed consensus workflows.
+- New memory semantics beyond existing endpoints.
+
+## Architecture Decision
+
+Prefer **adapter-first** design:
+
+- Keep `src/core` and `src/api` as source of truth.
+- Add `src/mcp/server.py` (MCP transport + tool registry).
+- Add `src/mcp/adapters/api_adapter.py` to reuse validated API contracts.
+- Add `src/mcp/schemas.py` for tool input/output validation.
+
+Reason: minimizes behavior drift and reuses existing validation/security paths.
+
+## Proposed MCP Tools (Phase 1)
+
+1. `memory_store`
+ - Input: `content`, `metadata?`, `agent_id?`, `ttl?`
+ - Backend: `POST /store`
+2. `memory_query`
+ - Input: `query`, `top_k?`, `agent_id?`
+ - Backend: `POST /query`
+3. `memory_get`
+ - Input: `memory_id`
+ - Backend: `GET /memory/{memory_id}`
+4. `memory_delete`
+ - Input: `memory_id`
+ - Backend: `DELETE /memory/{memory_id}`
+5. `memory_stats`
+ - Input: none
+ - Backend: `GET /stats`
+6. `memory_health`
+ - Input: none
+ - Backend: `GET /health`
+
+Optional (Phase 1.1):
+- `concept_define` and `analogy_solve` once primary tools are stable.
+
+## Security and Operational Guardrails
+
+- Require API key passthrough from MCP server to MnemoCore API.
+- Allowlist MCP tools (disable dangerous or experimental operations by default).
+- Enforce per-tool timeout and payload limits.
+- Structured logs with `trace_id`, `tool_name`, latency, status.
+- Fail closed for auth errors; fail open only where existing API already degrades by design.
+
+## Delivery Milestones
+
+### M0: Foundations (1-2 days)
+
+- Add MCP package structure.
+- Add config section for MCP host/port/timeouts/tool allowlist.
+- Add local run command and basic health check tool.
+
+Exit criteria:
+- MCP server starts and responds to health tool.
+
+### M1: Core Read/Write Tools (2-4 days)
+
+- Implement `memory_store`, `memory_query`, `memory_get`, `memory_delete`.
+- Map errors to stable MCP error format.
+- Add contract tests with mocked API responses.
+
+Exit criteria:
+- Core memory flow works end-to-end from MCP client.
+
+### M2: Observability + Hardening (1-2 days)
+
+- Add metrics counters/histograms for MCP tools.
+- Add retry/backoff only for transient failures.
+- Add degraded-mode tests (Redis/Qdrant unavailable).
+
+Exit criteria:
+- Clear diagnostics for failures and latency.
+
+### M3: Extended Cognitive Tools (optional, 1-2 days)
+
+- Add `concept_define` and `analogy_solve`.
+- Add docs examples for agent orchestration flows.
+
+Exit criteria:
+- Conceptual tools pass contract tests and are documented.
+
+## Test Strategy
+
+- Unit tests: schema validation, adapter mapping, error translation.
+- Functional tests: MCP client -> server -> API in local integration mode.
+- Resilience tests: upstream timeout, 403 auth fail, 404 memory miss, degraded Redis.
+- Regression gate: existing `tests/` suite remains green.
+
+## Rollout Plan
+
+1. Ship behind `mcp.enabled: false` default.
+2. Enable in beta environments only.
+3. Observe for one sprint (latency, error rate, tool usage).
+4. Promote to default-on after stability criteria are met.
+
+## Success Metrics
+
+- >= 99% successful MCP tool calls in healthy environment.
+- P95 MCP tool latency <= 300 ms for read operations (local setup target).
+- Zero contract-breaking changes without changelog entry.
+
+## Minimal Backlog Tasks
+
+1. Create `src/mcp/server.py` bootstrap.
+2. Create adapter + schemas.
+3. Add MCP config in `config.yaml` + typed config model.
+4. Add tests in `tests/test_mcp_server.py` and `tests/test_mcp_contracts.py`.
+5. Add documentation section in README + API docs.

+
+## Performance Optimization Tips
+
+1. Use BinaryHDV instead of float HDV.
+2. Use batch operations for bulk work.
+3. Keep Redis connection pools right-sized.
+4. Enable Qdrant binary quantization for faster search.
+
+## Monitoring
+
+Prometheus metrics are exposed at `/metrics` endpoint:
+- `mnemocore_store_duration_seconds` - Store operation latency
+- `mnemocore_query_duration_seconds` - Query operation latency
+- `mnemocore_memory_count_total` - Total memories per tier

+
+---
+
+## Phase 5.x: The Perfect Brain
+
+**Vision:** Transform MnemoCore from a sophisticated memory storage system into a truly cognitive architecture that functions as an artificial brain - but better.
+
+### 5.0 Multi-Modal Memory
+
+**Goal:** Enable storage and retrieval of images, audio, code structures, and cross-modal associations.
+
+```
+┌─────────────────────────────────────────────────────────────────┐
+│ CURRENT: Text-only encoding │
+│ ────────────────────────────────────────────────────────────── │
+│ store("User reported bug") → BinaryHDV │
+│ │
+│ FUTURE: Multi-modal encoding │
+│ ────────────────────────────────────────────────────────────── │
+│ store("Screenshot of error", image=bytes) → CrossModalHDV │
+│ store("Voice note", audio=bytes) → AudioHDV │
+│ bind(text_id, image_id, relation="illustrates") │
+│ │
+│ query("API error", modality="image") → screenshot.png │
+│ query(image=bytes, modality="text") → "Related conversation" │
+└─────────────────────────────────────────────────────────────────┘
+```
+
+**Implementation Plan:**
+
+| Component | Description | Dependencies |
+|-----------|-------------|--------------|
+| `MultiModalEncoder` | Abstract encoder protocol | - |
+| `CLIPEncoder` | Vision encoding via CLIP | `transformers`, `torch` |
+| `WhisperEncoder` | Audio encoding via Whisper | `openai-whisper` |
+| `CodeEncoder` | AST-aware code encoding | `tree-sitter` |
+| `CrossModalBinding` | VSA operations across modalities | BinaryHDV |
+
+**New API Endpoints:**
+```
+POST /store/multi - Store with multiple modalities
+POST /query/cross-modal - Cross-modal semantic search
+POST /bind - Bind modalities together
+GET /memory/{id}/related - Get cross-modal related memories
+```
+
+---
+
+### 5.1 Emotional/Affective Layer
+
+**Goal:** Enable emotion-weighted memory storage, retrieval, and decay - mimicking how biological memory prioritizes emotionally significant events.
+
+```
+┌─────────────────────────────────────────────────────────────────┐
+│ EMOTIONAL DIMENSIONS │
+│ ────────────────────────────────────────────────────────────── │
+│ │
+│ Valence: [-1.0 ──────────────── +1.0] │
+│ (negative/unpleasant) (positive/pleasant) │
+│ │
+│ Arousal: [0.0 ────────────────── 1.0] │
+│ (calm/neutral) (intense/urgent) │
+│ │
+│ EFFECT ON MEMORY: │
+│ ────────────────────────────────────────────────────────────── │
+│ High Arousal + Negative = "Flashbulb memory" (never forget) │
+│ High Arousal + Positive = Strong consolidation │
+│ Low Arousal = Faster decay (forgettable) │
+│ │
+└─────────────────────────────────────────────────────────────────┘
+```
+
+**MemoryNode Extensions:**
+```python
+@dataclass
+class MemoryNode:
+ # ... existing fields ...
+
+ # Phase 5.1: Emotional tagging
+ emotional_valence: float = 0.0 # -1.0 (negative) to +1.0 (positive)
+ emotional_arousal: float = 0.0 # 0.0 (calm) to 1.0 (intense)
+ emotional_tags: List[str] = field(default_factory=list) # ["frustration", "joy", "urgency"]
+
+ def emotional_weight(self) -> float:
+ """Calculate memory importance based on emotional factors."""
+ # Arousal amplifies retention regardless of valence
+ # High arousal creates "flashbulb memories"
+ return abs(self.emotional_valence) * self.emotional_arousal
+```
+
+**Modified LTP Formula:**
+```
+S = I × log(1+A) × e^(-λT) × (1 + E)
+
+Where E = emotional_weight() ∈ [0, 1]
+```
+
+**Use Cases:**
+- B2B outreach: "Customer was almost in tears when we fixed their issue" → HIGH priority
+- Support tickets: "User furious about data loss" → Never forget, prioritize retrieval
+- Positive feedback: "User loved the new feature" → Moderate retention
+
+---
+
+### 5.2 Working Memory Layer
+
+**Goal:** Active cognitive workspace for goal-directed reasoning, not just passive storage.

+# MnemoCore Self-Improvement Deep Dive
+
+Status: Design document (pre-implementation)
+Date: 2026-02-18
+Scope: Latent, always-on memory self-improvement loop that runs safely in production-like beta.
+
+## 1. Purpose
+
+This document defines a production-safe design for a latent self-improvement loop in MnemoCore.
+The goal is to continuously improve memory quality over time without corrupting truth, overloading resources, or breaking temporal-memory behavior.
+
+Primary outcomes:
+- Better memory quality (clarity, consistency, retrieval utility).
+- Better long-term structure (less duplication, stronger semantic links).
+- Preserved auditability and rollback.
+- Compatibility with temporal timelines (`previous_id`, `unix_timestamp`, time-range search).
+
+## 2. Current System Baseline
+
+Relevant existing mechanisms already in code:
+- `HAIMEngine.store/query` orchestration and subconscious queue (`src/core/engine.py`).
+- Background dream strengthening and synaptic binding (`src/core/engine.py`).
+- Gap detection and autonomous gap filling (`src/core/gap_detector.py`, `src/core/gap_filler.py`).
+- Semantic consolidation workers (`src/core/semantic_consolidation.py`, `src/subconscious/consolidation_worker.py`).
+- Subconscious daemon loop with LLM-powered cycles (`src/subconscious/daemon.py`).
+- Temporal memory fields in node model (`src/core/node.py`): `previous_id`, `unix_timestamp`, `iso_date`.
+- Tiered persistence and time-range aware search (`src/core/tier_manager.py`, `src/core/qdrant_store.py`).
+
+Implication: Self-improvement should reuse these pathways, not bypass them.
+
+## 3. Problem Definition
+
+Without a dedicated self-improvement loop, memory quality drifts:
+- Duplicate or near-duplicate content accumulates.
+- Weakly structured notes remain unnormalized.
+- Conflicting memories are not actively reconciled.
+- Query utility depends too much on initial storage quality.
+
+At the same time, naive autonomous rewriting is risky:
+- Hallucinated edits can reduce truth quality.
+- Over-aggressive rewriting can erase provenance.
+- Continuous background jobs can starve main workloads.
+
+## 4. Design Principles
+
+1. Append-only evolution, never destructive overwrite.
+2. Improvement proposals must pass validation gates before commit.
+3. Full provenance and rollback path for every derived memory.
+4. Temporal consistency is mandatory (timeline must remain navigable).
+5. Resource budgets and kill switches must exist from day 1.
+
+## 5. Target Architecture
+
+## 5.1 New Component
+
+Add `SelfImprovementWorker` as a background worker (similar lifecycle style to consolidation/gap-filler workers).
+
+Suggested location:
+- `src/subconscious/self_improvement_worker.py`
+
+Responsibilities:
+- Select candidates from HOT/WARM.
+- Produce improvement proposals (rule-based first, optional LLM later).
+- Validate proposals.
+- Commit accepted proposals via `engine.store(...)`.
+- Link provenance metadata.
+- Emit metrics and decision logs.
+
+## 5.2 Data Flow
+
+1. Candidate Selection
+2. Proposal Generation
+3. Validation & Scoring
+4. Commit as New Memory
+5. Link Graph/Timeline
+6. Monitor + Feedback Loop
+
+No in-place mutation of existing memory content.
+
+## 5.3 Integration Points
+
+- Read candidates: `TierManager` (`hot`, optional warm sampling).
+- Commit: `HAIMEngine.store(...)` so all normal indexing/persistence paths apply.
+- Timeline compatibility: preserve `previous_id` semantics and set provenance fields.
+- Optional post-effects: trigger low-priority synapse/link updates.
+
+## 6. Memory Model Additions (Metadata, not schema break)
+
+Use metadata keys first (backward compatible):
+- `source: "self_improvement"`
+- `improvement_type: "normalize" | "summarize" | "deduplicate" | "reconcile"`
+- `derived_from: ""`
+- `derived_from_many: [node_ids...]` (for merge/reconcile)
+- `improvement_score: float`
+- `validator_scores: { ... }`
+- `supersedes: ""` (logical supersedence, not deletion)
+- `version_tag: "vN"`
+- `safety_mode: "strict" | "balanced"`
+
+Note: Keep temporal fields from `MemoryNode` untouched and naturally generated on store.
+
+## 7. Candidate Selection Strategy
+
+Initial heuristics (cheap and deterministic):
+- High access + low confidence retrieval history.
+- Conflicting memories in same topical cluster.
+- Redundant near-duplicates.
+- Old high-value memories needing compaction.
+
+Selection constraints:
+- Batch cap per cycle.
+- Max candidates per source cluster.
+- Cooldown per `node_id` to avoid thrashing.
+
+## 8. Proposal Generation Strategy
+
+Phase A (no LLM dependency):
+- Normalize formatting.
+- Metadata repair/completion.
+- Deterministic summary extraction.
+- Exact/near duplicate merge suggestion.
+
+Phase B (LLM-assisted, guarded):
+- Rewrite for clarity.
+- Multi-memory reconciliation draft.
+- Explicit uncertainty markup if conflict unresolved.
+
+All proposals must include rationale + structured diff summary.
+
+## 9. Validation Gates (Critical)
+
+A proposal is committed only if all required gates pass:
+
+1. Semantic drift gate
+- Similarity to origin must stay above threshold unless `improvement_type=reconcile`.
+
+2. Fact safety gate
+- No new unsupported claims for strict mode.
+- If unresolved conflict: enforce explicit uncertainty markers.
+
+3. Structure gate
+- Must improve readability/compactness score beyond threshold.
+
+4. Policy gate
+- Block forbidden metadata changes.
+- Block sensitive tags crossing trust boundaries.
+
+5. Resource gate
+- Cycle budget, latency budget, queue/backpressure checks.
+
+Rejected proposals are logged but not committed.
+
+## 10. Interaction with Temporal Memory (Hard Requirement)
+
+This design must not break timeline behavior introduced around:
+- `previous_id` chaining
+- `unix_timestamp` payload filtering
+- Qdrant time-range retrieval
+
+Rules:
+- Every improved memory is a new timeline event (new node id).
+- `derived_from` models lineage; `previous_id` continues temporal sequence.
+- Query paths that use `time_range` must continue functioning identically.
+- Do not bypass `TierManager.add_memory` or Qdrant payload generation.
+
+## 11. Safety Controls & Operations
+
+Mandatory controls:
+- Config kill switch: `self_improvement_enabled: false` by default initially.
+- Dry-run mode: generate + validate, but do not store.
+- Strict mode for early rollout.
+- Per-cycle hard caps (count, wall-clock, token budget).
+- Circuit breaker on repeated validation failures.
+
+Operational observability:
+- Attempted/accepted/rejected counters.
+- Rejection reasons cardinality-safe labels.
+- End-to-end cycle duration.
+- Queue depth and backlog age.
+- Quality delta trend over time.
+
+## 12. Suggested Config Block
+
+Add under `haim.dream_loop` or sibling block `haim.self_improvement`:
+
+```yaml
+self_improvement:
+ enabled: false
+ dry_run: true
+ safety_mode: "strict" # strict | balanced
+ interval_seconds: 300
+ batch_size: 8
+ max_cycle_seconds: 20
+ max_candidates_per_topic: 2
+ cooldown_minutes: 120
+ min_improvement_score: 0.15
+ min_semantic_similarity: 0.82
+ allow_llm_rewrite: false
+```
+
+## 13. Metrics (Proposed)
+
+- `mnemocore_self_improve_attempts_total`
+- `mnemocore_self_improve_commits_total`
+- `mnemocore_self_improve_rejects_total`
+- `mnemocore_self_improve_cycle_duration_seconds`
+- `mnemocore_self_improve_candidates_in_cycle`
+- `mnemocore_self_improve_quality_delta`
+- `mnemocore_self_improve_backpressure_skips_total`
+
+## 14. Phased Implementation Plan
+
+Phase 0: Instrumentation + dry-run only
+- Add worker scaffold + metrics + decision logs.
+- No writes.
+
+Phase 1: Deterministic improvements only
+- Metadata normalization, duplicate handling suggestions.
+- Strict validation.
+- Commit append-only derived nodes.
+
+Phase 2: Controlled LLM improvements
+- Enable `allow_llm_rewrite` behind feature flag.
+- Add stricter validation and capped throughput.
+
+Phase 3: Reconciliation and adaptive policies
+- Multi-memory conflict reconciliation.
+- Learning policies from acceptance/rejection outcomes.
+
+## 15. Test Strategy
+
+Unit tests:
+- Candidate selection determinism and cooldown behavior.
+- Validation gates (pass/fail matrices).
+- Provenance metadata correctness.
+
+Integration tests:
+- Store/query behavior unchanged under disabled mode.
+- Time-range query still correct with improved nodes present.
+- Qdrant payload contains expected temporal + provenance fields.
+
+Soak/load tests:
+- Worker under sustained ingest.
+- Backpressure behavior.
+- No unbounded queue growth.
+
+Regression guardrails:
+- No overwrite of original content.
+- No bypass path around `engine.store`.
+
+## 16. Risks and Mitigations
+
+Risk: hallucinated improvements
+Mitigation: strict mode, no-LLM phase first, fact safety gate.
+
+Risk: timeline noise from too many derived nodes
+Mitigation: cooldown, batch caps, minimum score thresholds.
+
+Risk: resource contention
+Mitigation: cycle time caps, skip when main queue/backlog high.
+
+Risk: provenance complexity
+Mitigation: standardized metadata contract and audit logs.
+
+## 17. Open Decisions
+
+1. Should self-improved nodes be visible by default in top-k query, or weighted down unless requested?
+2. Should `supersedes` influence retrieval ranking automatically?
+3. Do we need a dedicated “truth tier” for validated reconciled memories?
+
+## 18. Recommended Next Step
+
+Implement Phase 0 only:
+- Worker skeleton
+- Config block
+- Metrics
+- Dry-run reports
+
+Then review logs for 1-2 weeks before enabling any writes.

+
+## Production Deployment
+
+### 1. Create Secrets
+
+```bash
+# Create API key secret
+kubectl create secret generic mnemocore-api-key \
+ --from-literal=HAIM_API_KEY='your-secure-api-key' \
+ -n mnemocore
+
+# Or use sealed-secrets/external-secrets for GitOps
+```
+
+### 2. Configure Storage
+
+```bash
+# Ensure you have a storage class configured
+kubectl get storageclass
+
+# For production, use fast SSD storage
+helm install mnemocore ./helm/mnemocore \
+ --namespace mnemocore \
+ --set global.storageClass=fast-ssd \
+ --set mnemocore.persistence.size=50Gi \
+ --set redis.persistence.size=20Gi \
+ --set qdrant.persistence.size=200Gi
+```
+
+### 3. Enable Ingress
+
+```bash
+helm install mnemocore ./helm/mnemocore \
+ --namespace mnemocore \
+ --set mnemocore.ingress.enabled=true \
+ --set mnemocore.ingress.className=nginx \
+ --set 'mnemocore.ingress.hosts[0].host=mnemocore.yourdomain.com' \
+ --set 'mnemocore.ingress.hosts[0].paths[0].path=/' \
+ --set 'mnemocore.ingress.hosts[0].paths[0].pathType=Prefix' \
+ --set 'mnemocore.ingress.tls[0].secretName=mnemocore-tls' \
+ --set 'mnemocore.ingress.tls[0].hosts[0]=mnemocore.yourdomain.com'
+```
+
+### 4. Enable Network Policies
+
+```bash
+helm install mnemocore ./helm/mnemocore \
+ --namespace mnemocore \
+ --set networkPolicy.enabled=true
+```
+
+## Monitoring
+
+### Prometheus Integration
+
+```bash
+# Enable ServiceMonitor for Prometheus Operator
+helm install mnemocore ./helm/mnemocore \
+ --namespace mnemocore \
+ --set serviceMonitor.enabled=true \
+ --set serviceMonitor.labels.release=prometheus
+```
+
+### Available Metrics
+
+MnemoCore exposes the following metrics on port 9090:
+
+- `mnemocore_memory_count_total` - Total number of memories stored
+- `mnemocore_memory_tier_hot` - Number of memories in hot tier
+- `mnemocore_memory_tier_warm` - Number of memories in warm tier
+- `mnemocore_memory_tier_cold` - Number of memories in cold tier
+- `mnemocore_query_duration_seconds` - Query latency histogram
+- `mnemocore_ltp_avg` - Average LTP score
+- `mnemocore_api_requests_total` - Total API requests
+- `mnemocore_api_request_duration_seconds` - API request latency
+
+### Grafana Dashboard
+
+Import the provided `grafana-dashboard.json` to visualize MnemoCore metrics.
+
+## Scaling
+
+### Manual Scaling
+
+```bash
+# Scale to 5 replicas
+kubectl scale deployment mnemocore --replicas=5 -n mnemocore
+```
+
+### Autoscaling
+
+HPA is enabled by default. Customize scaling behavior:
+
+```bash
+helm upgrade mnemocore ./helm/mnemocore \
+ --namespace mnemocore \
+ --set mnemocore.autoscaling.minReplicas=3 \
+ --set mnemocore.autoscaling.maxReplicas=50 \
+ --set mnemocore.autoscaling.targetCPUUtilizationPercentage=50
+```
+
+## Upgrading
+
+```bash
+# Upgrade to a new version
+helm upgrade mnemocore ./helm/mnemocore \
+ --namespace mnemocore \
+ --set mnemocore.image.tag=v3.6.0
+
+# Rollback if needed
+helm rollback mnemocore -n mnemocore
+```
+
+## Troubleshooting
+
+### Check Logs
+
+```bash
+# MnemoCore logs
+kubectl logs -l app.kubernetes.io/name=mnemocore -n mnemocore -f
+
+# Redis logs
+kubectl logs -l app.kubernetes.io/component=redis -n mnemocore -f
+
+# Qdrant logs
+kubectl logs -l app.kubernetes.io/component=qdrant -n mnemocore -f
+```
+
+### Common Issues
+
+1. **Pod stuck in Pending**
+ - Check storage class availability
+ - Check resource requests vs node capacity
+
+2. **Health check failing**
+ - Check Redis and Qdrant connectivity
+ - Verify environment variables
+
+3. **High memory usage**
+ - Reduce `mnemocore.config.tiers.hot.max_memories`
+ - Enable GPU for faster encoding
+
+### Debug Mode
+
+```bash
+# Run with debug logging
+helm upgrade mnemocore ./helm/mnemocore \
+ --namespace mnemocore \
+ --set mnemocore.env.logLevel=DEBUG
+```
+
+## Uninstalling
+
+```bash
+# Remove the Helm release
+helm uninstall mnemocore -n mnemocore
+
+# Remove the namespace (optional)
+kubectl delete namespace mnemocore
+
+# Remove PVCs (caution: data loss)
+kubectl delete pvc -n mnemocore --all
+```
+

+# MnemoCore Core
+
+## Beta Notice
+
+This core implementation is in beta.
+Behavior, interfaces, and internals may change without backward compatibility guarantees.
+
+## Purpose
+
+`src/core` contains the runtime memory engine and foundational primitives:
+- vector encoding,
+- memory node lifecycle,
+- tier placement,
+- synaptic associations,
+- configuration and storage adapters.
+
+## Main Modules
+
+- `engine.py` – Core orchestration for store/query and conceptual proxy operations.
+- `binary_hdv.py` – Binary vector operations and text encoding utilities.
+- `tier_manager.py` – HOT/WARM/COLD movement and persistence strategy.
+- `node.py` – Memory node data model and access/LTP-related behavior.
+- `synapse.py` – Synaptic edge model and reinforcement dynamics.
+- `config.py` – Typed config loading (`config.yaml` + `HAIM_*` overrides).
+- `async_storage.py` – Async Redis metadata and stream support.
+
+## Example
+
+```python
+from mnemocore.core.engine import HAIMEngine
+
+engine = HAIMEngine()
+memory_id = engine.store("The quick brown fox")
+results = engine.query("quick fox", top_k=3)
+print(memory_id, results)
+```
+
+## Testing
+
+Run from repo root:
+
+```bash
+python -m pytest tests -v
+```
+
+## More Docs
+
+- `docs/ARCHITECTURE.md`
+- `docs/ROADMAP.md`

+ 2. A XOR attention mask is generated: mask = query XOR context_key
+ This creates a residual vector that is ORTHOGONAL to the context,
+ effectively suppressing already-known dimensions and amplifying novel ones.
+ 3. Query results are re-ranked by a composite score:
+ composite = alpha * raw_similarity + beta * novelty_boost(mask, mem_hdv)
+ 4. The mask is also available for downstream gap-detection.
+
+Motivation (VSA theory):
+ - XOR in binary HDV space is the self-inverse binding operator.
+ - query.xor(context) ≈ "what about this query is NOT already represented in context?"
+ - Hamming similarity(mask, candidate) ≈ novelty of candidate relative to context.
+
+Phase 4.1: XOR-based Project Isolation
+======================================
+XORIsolationMask provides deterministic project-based memory isolation:
+
+ - Each project_id derives a unique binary mask via SHA256(project_id) -> seed -> RNG
+ - store(): masked_hdv = original_hdv XOR project_mask
+ - query(): unmasked_query = query_hdv XOR project_mask (then search in masked space)
+ - Memories from different projects are effectively orthogonal (~50% similarity)

+Bayesian Long-Term Potentiation (LTP) Feedback Loop (Phase 4.0)
+================================================================
+Replaces the simple Hebbian LTP update with a Bayesian reliability model.
+
+Core idea:
+ Each synaptic connection and each memory node maintains a Beta distribution
+ over its "true reliability" p ~ Beta(α, β).
+
+ - α = accumulated success evidence (hits, correct retrievals)
+ - β = accumulated failure evidence (misses, wrong retrievals, decay)
+
+ The posterior mean E[p] = α / (α + β) is used as the reliability estimate.
+ The posterior variance Var[p] = αβ / ((α+β)²(α+β+1)) reflects uncertainty.
+
+ On each firing:
+ success → α += 1 (evidence for reliability)
+ failure → β += 1 (evidence for unreliability)
+
+ The LTP update on MemoryNode follows the same Beta model, where:
+ - "success" events: retrieval that helped produce a good answer
+ - "failure" events: retrieval miss, low-EIG storage, or forced decay
+
+Benefits over plain Hebbian:
+ - Uncertainty-aware: new synapses have wide credible intervals → exploration bonus
+ - Natural regularization: α and β act as pseudo-counts preventing overconfidence
+ - Compatible with existing strength/ltp_strength fields (posterior mean replaces raw strength)

+Binary Hyperdimensional Vector (Binary HDV) Core
+=================================================
+Phase 3.0 implementation of binary VSA operations.
+
+Based on Kanerva's Hyperdimensional Computing theory (2009).
+Uses standard mathematical operations (XOR, Hamming distance, majority bundling)
+that are fundamental VSA primitives — not derived from any proprietary implementation.
+
+Key design choices:
+ - D = 16,384 bits (2^14) — configurable via config.yaml
+ - Storage: packed as np.uint8 arrays (D/8 bytes = 2,048 bytes per vector)
+ - Similarity: Hamming distance (popcount of XOR result)
+ - Binding: element-wise XOR (self-inverse, commutative)
+ - Bundling: element-wise majority vote (thresholded sum)
+ - Sequence: circular bit-shift (permutation)
+
+All batch operations are NumPy-vectorized (no Python loops for distance computation).

+MnemoCore Domain-Specific Exceptions
+=====================================
+
+This module defines a hierarchy of exceptions for consistent error handling
+across the MnemoCore system.
+
+Exception Hierarchy:
+ MnemoCoreError (base)
+ ├── RecoverableError (transient, retry possible)
+ │ ├── StorageConnectionError
+ │ ├── StorageTimeoutError
+ │ └── CircuitOpenError
+ ├── IrrecoverableError (permanent, requires intervention)
+ │ ├── ConfigurationError
+ │ ├── DataCorruptionError
+ │ ├── ValidationError
+ │ ├── NotFoundError
+ │ └── UnsupportedOperationError
+ └── Domain Errors (mixed recoverability)
+ ├── StorageError
+ ├── VectorError
+ │ ├── DimensionMismatchError
+ │ └── VectorOperationError
+ └── MemoryOperationError
+
+Usage Guidelines:
+ - Return None for "not found" scenarios (expected case, not an error)
+ - Raise exceptions for actual errors (connection failures, validation, corruption)
+ - Always include context in error messages
+ - Use error_code for API responses

+Knowledge Gap Detection — Proactive Curiosity Engine (Phase 4.0)
+================================================================
+Detects "gaps" in the memory system: topics the engine has been queried
+about but lacks sufficient high-quality information to answer confidently.
+
+Gap detection signals:
+ 1. Low retrieval confidence: top-k query returns results with average
+ similarity below a threshold (engine didn't know much about it).
+ 2. Sparse coverage: fewer than min_results candidates were retrieved.
+ 3. High EIG residual: the XOR attention mask still has high Hamming
+ entropy after retrieval (the query dimension is underrepresented).
+ 4. Explicit negative feedback: caller marks a retrieval as unhelpful.
+
+Each detected gap is stored as a GapRecord in the gap registry.
+The registry is periodically inspected by the gap-filling LLM component.
+
+Public API:
+ detector = GapDetector(engine)
+
+ # After a query:
+ gaps = await detector.assess_query(query_text, results, attention_mask)
+
+ # Register explicit negative feedback:
+ await detector.register_negative_feedback(query_text)

+Autonomous Gap-Filling via LLM Integration (Phase 4.0)
+======================================================
+Bridges the GapDetector with the existing HAIMLLMIntegrator to autonomously
+fill detected knowledge gaps by generating and storing synthetic memories.
+
+Pipeline:
+ 1. GapFiller polls GapDetector for high-priority open gaps.
+ 2. For each gap, it constructs a prompt asking the LLM to fill it.
+ 3. The LLM response is parsed into discrete factual statements.
+ 4. Each statement is stored in the engine as a new memory node, tagged
+ with metadata: {"source": "llm_gap_fill", "gap_id": ..., "query": ...}.
+ 5. The gap record is marked as filled in the detector registry.
+
+Safety controls:
+ - Rate-limiting: max N gap-fill calls per hour (configurable).
+ - Confidence gate: only fill gaps that stay unresolved after min_reqs queries.
+ - Dry-run mode: generate responses but don't store them.
+ - Minimum priority threshold before triggering LLM calls.
+
+Usage:
+ filler = GapFiller(engine, integrator, detector)
+ await filler.start() # background task
+ results = await filler.fill_now(n=5) # immediate fill of top-5 gaps
+ await filler.stop()

+HNSW ANN Index Extension for HOT tier (Phase 4.0)
+==================================================
+Extends the existing FAISS binary flat index with a configurable

+ - Graceful fallback to flat index when FAISS unavailable or N is small.
+
+This module provides HNSWIndexManager which is meant to be composed
+into TierManager (or used standalone for testing).

+Auto-Associative Cleanup Loop — Vector Immunology (Phase 4.0)
+==============================================================
+Inspired by Biological Immune System & Hopfield-network attractor dynamics.
+
+The "vector immune system" of MnemoCore continuously monitors the HOT tier for:
+
+ 1. Semantic Drift: memories whose stored HDV has drifted far from its own
+ nearest-neighbor cluster (i.e. it is now an isolated outlier).
+ → Action: re-encode from stored content string, or flag for review.
+
+ 2. Corrupted / Low-Signal Nodes: nodes with near-zero LTP AND high HDV entropy
+ (effectively random vectors with no semantic content).
+ → Action: quarantine (move to COLD) or prune.
+
+ 3. Stale Synaptic Noise: decayed synapses that waste adjacency-list memory.
+ → Action: (delegates to engine.cleanup_decay)
+
+ 4. HDV Auto-correction (Attractor Convergence):
+ A simplified Hopfield-style convergence step:
+ v_clean = sign(W · v)
+ where W = superposition of the k nearest clean prototype vectors.
+ This "snaps" a slightly noisy vector to its nearest attractor basin.
+
+Biological analogy:
+ - Innate immune response → fast outlier / corruption detection
+ - Adaptive immune response → targeted re-encoding of drifted memories
+ - Memory T-cells (long-lived) → proto-memories (semantic consolidation)

+RecursiveSynthesizer – Phase 4.5: Recursive Synthesis Engine
+=============================================================
+MnemoCore's implementation of the Recursive Language Models (RLM) concept
+from MIT CSAIL (arXiv:2512.24601, Zhang, Kraska, Khattab).
+
+The core idea: instead of loading all memories into an LLM's context window
+(causing "Context Rot"), we:
+
+1. DECOMPOSE – Break a complex query into focused sub-queries
+2. SEARCH – Run each sub-query against MnemoCore in PARALLEL
+3. RECURSE – If a cluster is too large/uncertain, spawn a sub-agent call
+4. SYNTHESIZE – Merge all sub-results into a final ranked answer
+
+This means AI agents using MnemoCore never need to load all memories into
+their context — they just ask the RecursiveSynthesizer to find what's relevant.

+"""
+Nightly Semantic Consolidation Worker (Phase 4.0)
+=================================================
+Autonomous background worker that runs semantic clustering over the
+WARM tier every night (configurable schedule) to:
+
+ 1. Cluster semantically similar memories using Hamming-distance k-medoids.
+ 2. For each cluster, compute a "proto-memory" via majority-vote bundling.
+ 3. Detect redundant / near-duplicate memories (distance < epsilon).
+ 4. Optionally prune low-LTP duplicates and strengthen the proto-memory.
+ 5. Emit consolidation events to Redis stream for downstream consumers.
+
+Design principles:
+ - Runs as a standalone asyncio task; no hard dependency on Redis (falls back gracefully).
+ - All computation is NumPy-vectorized (no Python-level loops over dimension).
+ - Idempotent: running twice produces the same result.
+ - Pluggable: attach a post_consolidation_hook for custom logic.
+
+Usage:
+ worker = SemanticConsolidationWorker(engine)
+ await worker.start() # launches background task
+ await worker.run_once() # one-shot (for testing / cron)
+ await worker.stop()

+Synapse Adjacency Index — O(1) Lookup (Phase 4.0)
+=================================================
+Provides a hardened, thread-safe adjacency data structure for synaptic
+connections with guaranteed O(1) lookup, O(1) insert, and O(k) neighbour
+enumeration (where k = degree of a node).
+
+Design:
+ - Primary store: Dict[Tuple[str,str], SynapticConnection]
+ Key is always sorted(a, b) to ensure uniqueness regardless of direction.
+ - Adjacency index: Dict[str, set[str]]
+ Maps node_id → set of connected node_ids. Lookup is O(1), iteration O(k).
+ - The set-based adjacency replaces the previous list-based one to prevent
+ duplicate edges and make removals O(1) instead of O(k).
+
+Phase 4.0 additions:
+ - Bayesian LTP state is serialised alongside Hebbian state on save.
+ - adjacency_degree() exposes per-node connectivity (used by immunology sweep).
+ - to_dict() / from_dict() for full serialisation round-trips.
+ - compact() removes all edges below a strength threshold in O(E) time.
+
+This module is intentionally dependency-light: it only imports stdlib +
+SynapticConnection + BayesianLTPUpdater from this package.

+Tiered Memory Management (Phase 3.5+)
+=====================================
+Manages memory lifecycle across HOT, WARM, and COLD tiers based on Long-Term Potentiation (LTP).
+
+Tiers:
+ - HOT (RAM): Fast access, limited capacity. Stores most relevant memories.
+ - WARM (Qdrant/Disk): Larger capacity, slightly slower access.
+ - COLD (Archive): Unlimited capacity, slow access. Compressed JSONL.
+
+Logic:
+ - New memories start in HOT.
+ - `consolidate()` moves memories between tiers based on LTP strength and hysteresis.
+ - Promote: WARM -> HOT if `ltp > threshold + delta`
+ - Demote: HOT -> WARM if `ltp < threshold - delta`
+ - Archive: WARM -> COLD if `ltp < archive_threshold` (or age)
+
+All vectors use BinaryHDV (packed uint8 arrays).

+# STUDY CASE: MnemoCore Phase 3.0 – The Adaptive Engine
+
+## 1. Executive Summary: From Prototype to Cognitive OS
+This study case documents the architectural evolution of **MnemoCore (Infrastructure for Persistent Cognitive Memory)** from a Phase 2.0 research prototype to a Phase 3.0 production-grade Cognitive Operating System.
+
+The core mission is to solve the "Scalability vs. Agency" paradox: How to maintain a coherent, high-dimensional memory for an autonomous agent that grows indefinitely on consumer-grade hardware (32GB RAM) without sacrificing real-time inference or kognitive stability.
+
+---
+
+## 2. The Architectural Consensus
+Based on a cross-model technical review (Advanced Reasoning Models), four critical pillars have been identified for the "Adaptive Engine" upgrade.
+
+### Pillar I: Robust Binary VSA (Vector Symbolic Architecture)
+The system transitions from 10,000-D bipolar vectors to **16,384-D (2^14) Binary Vectors**.
+* **The Problem:** Naive XOR-binding in low dimensions leads to "information collapse" and high collision rates in complex thought bundles.
+* **The Consensus Solution:**
+ * Increase dimensionality to **16k** to maximize entropy.
+ * Implement **Phase Vector Encoding**: Using dual vectors (Positive/Negative phase) to allow the representation of semantic opposites—a feature typically lost in pure binary space.
+ * **Result:** 100x speed increase using hardware-native bitwise XOR and `popcount` (Hamming distance).
+
+### Pillar II: Tri-State Memory Hierarchy (Memory Tiering)
+To achieve $O(log N)$ query speed, a biological-inspired storage hierarchy is implemented.
+* **HOT (The Overconscious):** RAM-resident dictionary (Top 2,000 nodes). Zero-latency access.
+* **WARM (The Subconscious):** SSD-resident HNSW index using **Memory-Mapping (mmap)**. This allows the OS to handle caching between RAM and Disk intelligently.
+* **COLD (The Archive):** Compressed JSONL on disk for deep training and long-term history.
+* **Hysteresis Layer:** To prevent "boundary thrashing" (nodes jumping between RAM and Disk), a soft boundary is implemented where a node needs a significant salience delta to change tiers.
+
+### Pillar III: Biological LTP (Long-Term Potentiation)
+Memory retention is shifted from a linear decay model to a biologically plausible reinforcement model.
+* **New Formula:** $S = I \times \log(1+A) \times e^{-\lambda T}$
+ * $I$: Initial importance.
+ * $A$: Successful retrieval count (Logarithmic reinforcement).
+ * $e^{-\lambda T}$: Exponential decay.
+* **Consolidation Plateau:** Once a memory reaches the "Permanence Threshold," it enters a structural phase-transition where it becomes immune to decay—forming the "Core Identity" of the agent.
+
+### Pillar IV: UMAP Cognitive Landscape
+* **The Decision:** Replace t-SNE with **UMAP (Uniform Manifold Approximation)**.
+* **Rationale:** UMAP is significantly faster for large datasets and preserves the global structure of the memory space better than t-SNE. This allows the User to visualize "Concept Clusters" and identify "Cognitive Drift" in real-time.
+
+---
+
+## 3. Implementation Roadmap (Phase 3.0)
+
+| Stage | Component | Objective |
+| :--- | :--- | :--- |
+| **01** | **Binary Core** | Implement `BinaryHDV` class with 16k dimension and XOR-binding. |
+| **02** | **Tier Manager** | Refactor `engine.py` with `MemoryTierManager` and mmap support. |
+| **03** | **LTP Logic** | Deploy the exponential decay and consolidation plateau. |
+| **04** | **VIZ Hub** | Build the UMAP visualization dashboard for memory auditing. |
+
+---
+
+## 4. Conclusion
+The MnemoCore Phase 3.0 architecture represents a shift toward **Sovereign Intelligence**. By separating the mathematical logic (Binary VSA) from the biological intent (LTP Decay), we create a system that doesn't just store data—it *evolves* with the user.
+
+---
+*Documented by MnemoCore Architect & User*

+# MnemoCore Vector Core (Experimental)
+
+## Beta Notice
+
+`vector_core` is an experimental area used for research tracks and prototypes.
+It should not be treated as stable production infrastructure.
+
+## Purpose
+
+This directory contains exploratory work related to:
+- retrieval/indexing approaches,
+- migration tooling,
+- Dream Stream related predictor experiments,
+- benchmarking ideas and concept validation.
+
+## Important Expectations
+
+- APIs and file formats can change quickly.
+- Performance notes in this folder are directional, not guaranteed.
+- Some documents describe proposed future directions, not completed product behavior.
+
+## Relationship to Main Runtime
+
+The main runtime path for MnemoCore is under `src/`.
+`vector_core/` should be read as supplementary research and prototyping material.
+
+## Suggested Use
+
+- Use this folder for isolated experiments.
+- Validate findings before integrating with `src/core`.
+- Keep reproducibility notes when running local trials.
+
+## Related Docs
+
+- `docs/ARCHITECTURE.md`

+# Omega-JEPA (Dream Stream) - Technical Specification
+
+## 1. Overview
+This document outlines the architecture for the Omega-JEPA Predictor Network, a clean-room implementation inspired by Joint Embedding Predictive Architectures (JEPA) but specialized for the "Dream Stream" environment. The core innovation is the integration of Protocol Omega metrics (Time-Reversal Asymmetry and Z-Scores) directly into the validation loop to ensure causal fidelity in state predictions.
+
+## 2. Theoretical Foundation
+### 2.1. The JEPA Paradigm
+Unlike generative models that predict pixels (x), JEPA predicts representations (y) in an abstract space.
+- **Context ($S_x$):** The current state representation.
+- **Action ($a$):** The control or transition vector.
+- **Latent ($z$):** A stochastic variable capturing uncertainty in the transition.
+- **Prediction ($S_y$):** The predicted future state representation.
+
+Equation: $S_y = Predictor(S_x, a, z)$
+
+### 2.2. Protocol Omega Integration
+To prevent the model from learning "easy" but non-causal shortcuts (representation collapse), we enforce Time-Reversal Asymmetry (TRA).
+- **TRA Hypothesis:** A valid causal transition $A \to B$ should be distinguishable from $B \to A$ in the latent energy landscape.
+- **Omega Score:** A composite metric combining prediction error (L2) with TRA violation penalties.
+
+## 3. Architecture Design
+
+### 3.1. `OmegaJEPA_Predictor` (The Brain)
+- **Type:** PyTorch `nn.Module`.
+- **Structure:** Multi-Layer Perceptron (MLP) with residual connections.
+- **Inputs:**
+ - `context_embedding`: Tensor [Batch, Dim]
+ - `action_vector`: Tensor [Batch, ActionDim]
+ - `latent_z`: Tensor [Batch, LatentDim] (Optional/sampled)
+- **Mechanism:**
+ 1. Concatenate $S_x$, $a$, and $z$.
+ 2. Pass through a high-dimensional projection layer.
+ 3. Apply LayerNorm and GeLU activations.
+ 4. Output projected state $\hat{S}_y$.
+
+### 3.2. `OmegaMetrics` (The Auditor)
+- **Purpose:** Stateless validator class to compute physics-inspired metrics.
+- **Key Metrics:**
+ - `compute_tra(state_t, state_t1)`: Measures asymmetry magnitude.
+ - `compute_z_score(residuals)`: Standard deviation based anomaly detection.
+ - `energy_function(state)`: Helper for TRA computation (e.g., magnitude or learned energy).
+
+## 4. Implementation Constraints
+- **Framework:** PyTorch (v2.x).
+- **Style:** Strict typing, modular design.
+- **Clean Room:** No usage of Meta/Facebook source code; strictly first-principles implementation based on LeCun's 2022 paper and Protocol Omega specs.
+
+## 5. Usage
+```python
+model = OmegaJEPA_Predictor(dim=256, action_dim=64)
+metrics = OmegaMetrics()
+
+# Forward pass
+s_next_pred = model(s_curr, action, z)
+
+# Validation
+tra_score = metrics.compute_tra(s_curr, s_next_pred)
+```

+# PREDICTIVE-MODEL PILOT — FINAL FORENSIC AUDIT (Dream Stream)
+
+**Target:** `MnemoCore/vector_core/dream_stream/`
+
+**Checkpoint loaded:** `checkpoints/predictive_model_latest.pt` (PyTorch `state_dict`)
+
+## Executive Summary
+Adaptive Logic gates were evaluated with controlled runs and then re-validated across multiple batches.
+
+**Model capability override note:** You requested switching the cognitive model to `openai-codex/gpt-5.3-preview`. In this environment I cannot change the underlying model identifier on demand; however, I *did* rerun the audit with stricter/more extensive statistical scrutiny (multi-batch robustness) and updated this report accordingly.
+
+1) **Resilience Check (Hallucination Injection):** PASS
+- **Expected:** High Signal_Z anomaly + Low Signal_Entropy (reversible / non-causal)
+- **Observed:** **High anomaly Signal_Z** and **low Signal_Entropy**
+
+2) **Dream Test (Valid Concept Sequence):** PASS
+- **Expected:** Low Signal_Z (organic) + High Signal_Entropy (irreversible / causal flow)
+- **Observed:** **Low anomaly Signal_Z** and **high Signal_Entropy**
+
+**Deployment status:** ✅ Green light (metrics separate hallucination-like events from organic dream flow).
+
+---
+
+## Environment & Components
+- **Python:** 3.12.3
+- **PyTorch:** 2.10.0+cu128 (CUDA available: **False** → ran on CPU)
+- **Checkpoint:** `checkpoints/omega_jepa_latest.pt`
+ - Size: **7,659,775 bytes**
+ - SHA-256: `d93a67f352270c7e199d26312163abed67daa7724d3e12659d4ba0e0cab89bc2`
+- **Model:** `core/predictor.py::PredictiveModel_Predictor`
+ - Parameter count: **1,912,064** (all trainable)
+ - Determinism check (eval mode, identical inputs): **PASS** (`allclose=True`)
+- **Metrics:** `core/adaptive_metrics.py::AdaptiveMetrics`
+ - Signal_Z implemented as `compute_signal_z(error_tensor)` (batch-relative)
+ - Signal_Entropy implemented as `compute_signal_entropy(state_t, state_t1)` using energy proxy `||x||_2`
+
+**Note on naming:** The code exposes `compute_z_score` / `compute_tra` (not `calculate_*`). This audit uses the implemented API.
+
+---
+
+## Test Methodology (Reproducible)
+Random seed set: `torch.manual_seed(42)`.
+
+### A) Dream Test (Organic Sequence)
+- Data source: `mock_data.py` via `get_dataloader(batch_size=64)`
+- Run:
+ 1. Load batch `(s_t, a_t, s_t1)`
+ 2. Predict `pred = model(s_t, a_t)`
+ 3. Error per sample: `mse_i = mean((pred - s_t1)^2)`
+ 4. **Signal_Z:** `z = compute_signal_z(mse)`
+ 5. **Signal_Entropy (irreversibility of true flow):** `entropy_true = compute_signal_entropy(s_t, s_t1)`
+
+### B) Forensic Stress Test (Hallucination / Noise)
+Two parts:
+
+**1) Signal_Z Anomaly Injection** (to ensure outlier detectability):
+- Same organic contexts/actions, but corrupt 4/64 targets with extreme noise:
+ - `s_t1[-4:] = 10 * randn()`
+- Compute `mse_h` and `z_h` over the mixed batch.
+
+**2) Signal_Entropy Reversibility on Pure Noise Transitions**:
+- Independent random states:
+ - `s_noise = randn()` and `s_noise1 = randn()`
+- Compute `entropy_noise = compute_signal_entropy(s_noise, s_noise1)`.
+
+---
+
+## Results
+
+### Gate 1 — Signal_Z Anomaly Detection
+| Scenario | Metric | Observed |
+|---|---:|---:|
+| Dream (valid sequence) | `max(z)` | **1.7314** |
+| Stress (4 extreme corruptions) | `max(z_h)` | **4.0629** |
+
+**Interpretation:**
+- Dream flow produces *no significant outliers* inside the batch (low maximum z-score).
+- Injected hallucination-like targets produce *strong, detectable outliers* (z > 4).
+
+**Status:** PASS
+
+### Gate 2 — Causal Entropy (Signal_Entropy)
+| Scenario | Metric | Observed |
+|---|---:|---:|
+| Dream (true transition) | `mean(TRA(s_t → s_t1))` | **0.8686** |
+| Stress (pure noise transition) | `mean(TRA(s_noise → s_noise1))` | **0.0840** |
+
+**Interpretation:**
+- Valid sequences exhibit **high TRA** (directional / irreversible energy change).
+- Pure noise transitions exhibit **low TRA** (reversible / non-causal energy behavior).
+
+**Status:** PASS
+
+---
+
+## Additional Scrutiny (High-Stakes Robustness)
+This section treats the audit as a critical gate: repeated sampling, parameter/seed controls, and explicit discussion of failure modes.
+
+### 1) Multi-batch Robustness (20 batches)
+Re-ran gates across **20 independent batches** (batch_size=64) with `torch.manual_seed(123)`.
+
+**Dream (valid sequence):**
+- `max(z)` mean **2.5782** (min **1.9524**, max **3.6534**)
+- `mean(MSE)` mean **1.4049** (tight spread)
+- `mean(TRA(s_t → s_t1))` mean **0.8047** (min **0.7376**, max **0.8727**)
+
+**Stress (4/64 extreme corruptions, 10× noise):**
+- `max(z_h)` mean **4.2026** (min **3.9452**, max **4.5169**)
+- `mean(MSE_h)` mean **7.6529**
+
+**Pure noise (reversibility control):**
+- `mean(TRA(s_noise → s_noise1))` mean **0.0622** (min **0.0393**, max **0.0816**)
+
+**Separation margin:**
+- `(max_z_stress − max_z_dream)` mean **1.6244** (min **0.5234**, max **2.2281**)
+
+### 2) Sensitivity Sweep: Corruption Fraction (K) × Noise Scale (σ)
+Re-ran a stronger stress grid across **50 batches** (`torch.manual_seed(321)`), corrupting the last **K** samples in each batch with `randn() * σ`.
+
+Baseline (Dream) over 50 batches:
+- `max(z)` mean **2.3415** (min **1.6521**, max **3.4722**)
+- `mean(TRA_true)` mean **0.8137** (min **0.7548**, max **0.8602**)
+- `mean(TRA_noise)` mean **0.0595** (min **0.0377**, max **0.0904**)
+
+Stress grid (reported as **mean max(z_h)** over 50 batches):
+- **K=1**: σ=1 → **4.03**, σ=3 → **7.84**, σ=10 → **7.87**
+- **K=2**: σ=1 → **3.85**, σ=3 → **5.81**, σ=10 → **5.81**
+- **K=4**: σ=1 → **3.81**, σ=3 → **4.25**, σ=10 → **4.21**
+- **K=8**: σ=1 → **3.51**, σ=3 → **3.05**, σ=10 → **3.02**
+
+**Critical nuance (precision caveat):** Z-score is computed **within-batch**. If a *large fraction* of the batch is corrupted (e.g., K=8/64) or corruption scale becomes extreme, the batch mean/std inflate and the maximum z-score can *decrease* even though absolute error is huge. This is expected behavior for batch-relative z-scores.
+
+**Implication:** For deployment gating, treat `max(z)` as an **outlier detector** (best when anomalies are sparse), and pair it with an **absolute error gate** (e.g., mean/quantile MSE) or a robust statistic (e.g., MAD-based z) if widespread corruption is a realistic threat model.
+
+### 3) Recommended Gate Policy (based on observed distributions)
+Given the above distributions, a conservative two-factor gate that matches the intended semantics is:
+- **Organic gate:** `mean(TRA_true) >= 0.6` AND `max(z) <= 3.8`
+- **Anomaly gate:** trigger if `max(z) >= 3.8` OR if `mean(MSE)` exceeds an absolute threshold calibrated from production reference data.
+
+These are *recommendations*; for absolute precision you should calibrate the MSE threshold using an empirical reference set representative of production conditions.
+
+## Conclusion
+Both Adaptive Logic gates behave as intended on the Dream Stream implementation:
+- **Hallucination-like corruption** is flagged via **high Z-score anomalies** (consistently ~4+ for injected outliers).
+- **Organic dream flow** shows **lower anomaly Z** and **higher TRA**, while **pure noise transitions** show **low TRA**.
+
+✅ **FINAL VERDICT: PASS — Predictive-Model metrics are operational and provide a viable deployment gate.**
