-### 🟡 Not Implemented (Requires LLM or Complex Setup)
-These tests depend on non-deterministic LLM behavior or require complex setup:
-1. Fact type override tests (3 tests) - Depends on LLM classification
-2. Confidence score tests (2 tests) - Depends on LLM opinion extraction
-3. Entity extraction tests (3 tests) - Depends on LLM entity detection
-4. Fact deduplication tests (3 tests) - Depends on LLM similarity detection
-5. Causal relationships tests (2 tests) - Depends on LLM causal extraction
-6. Embeddings tests (2 tests) - Would test internal implementation details
-
-### 🔵 Deferred (Lower Priority)
-7. Error handling (4 tests) - Infrastructure tests
-8. Performance tests (3 tests) - Requires specific benchmarking setup
-
----
-
-## Success Metrics
-
-- **Coverage**: 95%+ line coverage for retain code paths
-- **Reliability**: All tests pass consistently

+# Per-User Memory
+
+The simplest pattern: give your agent persistent memory for each user. The agent remembers past conversations, user preferences, and context across sessions.
+
+## The Problem
+
+Without memory, every conversation starts from scratch:
+
+```
+Session 1: "I prefer dark mode and use Python"
+Session 2: "What's my preferred language?" → Agent doesn't know
+```
+
+## The Solution: One Bank Per User
+
+```
+┌─────────────────┐     ┌─────────────────┐     ┌─────────────────┐
+│   User A Bank   │     │   User B Bank   │     │   User C Bank   │
+│                 │     │                 │     │                 │
+│  - Conversations│     │  - Conversations│     │  - Conversations│
+│  - Preferences  │     │  - Preferences  │     │  - Preferences  │
+│  - Context      │     │  - Context      │     │  - Context      │
+└─────────────────┘     └─────────────────┘     └─────────────────┘
+        │                       │                       │
+   100% isolated          100% isolated           100% isolated
+```
+
+Each user gets their own memory bank. Complete isolation, simple mental model.
+
+## Implementation
+
+### 1. Create a Bank When User Signs Up
+
+```python
+from hindsight import HindsightClient
+
+client = HindsightClient()
+
+def on_user_signup(user_id: str):
+    client.create_bank(
+        bank_id=f"user-{user_id}",
+        name=f"Memory for {user_id}"
+    )
+```
+
+### 2. Save Conversations After Each Session
+
+```python
+async def save_conversation(user_id: str, messages: list):
+    await client.retain(
+        bank_id=f"user-{user_id}",
+        content=messages  # [{"role": "user", "content": "..."}, ...]
+    )
+```
+
+### 3. Recall Context Before Responding
+
+```python
+async def get_context(user_id: str, query: str):
+    result = await client.recall(
+        bank_id=f"user-{user_id}",
+        query=query
+    )
+    return result.results
+```
+
+### 4. Complete Agent Loop
+
+```python
+async def handle_message(user_id: str, user_message: str):
+    # 1. Recall relevant context
+    context = await client.recall(
+        bank_id=f"user-{user_id}",
+        query=user_message
+    )
+
+    # 2. Build prompt with memory
+    prompt = f"""You are a helpful assistant with memory of past conversations.
+
+## What you remember about this user
+{format_results(context.results)}
+
+## Current message
+{user_message}
+"""
+
+    # 3. Generate response
+    response = await llm.complete(prompt)
+
+    # 4. Save the conversation
+    await client.retain(
+        bank_id=f"user-{user_id}",
+        content=[
+            {"role": "user", "content": user_message},
+            {"role": "assistant", "content": response}
+        ]
+    )
+
+    return response
+```
+
+## What Gets Remembered
+
+Hindsight automatically extracts and connects:
+
+- **Facts**: "User prefers Python", "User is building a CLI tool"
+- **Entities**: People, projects, technologies mentioned
+- **Relationships**: How entities relate to each other
+- **Temporal context**: When things happened
+
+You don't need to manually extract or structure this - just retain the conversations.
+
+## When to Use This Pattern
+
+**Good fit:**
+- Chatbots and assistants
+- Personal AI companions
+- Any 1:1 user-to-agent interaction
+
+**Consider adding shared knowledge if:**
+- You have product docs or FAQs to reference
+- Multiple users need access to the same information
+- See [Support Agent with Shared Knowledge](./support-agent-with-shared-knowledge)

+# Support Agent with Shared Knowledge
+
+This pattern shows how to build a support agent that combines **per-user memory** with **shared product knowledge** (RAG), giving users personalized support while leveraging a single source of truth for documentation.
+
+## The Problem
+
+You're building a support agent that needs to:
+- Remember each user's history, preferences, and past issues
+- Access shared product documentation
+- Keep user data completely isolated from other users
+
+A naive approach would index product docs into each user's memory bank, but this is expensive and wasteful (N copies for N users).
+
+## The Solution: Multi-Bank Architecture
+
+Create separate memory banks for different concerns:
+
+```
+┌─────────────────┐     ┌─────────────────┐     ┌─────────────────┐
+│   User A Bank   │     │   User B Bank   │     │  Shared Docs    │
+│                 │     │                 │     │     Bank        │
+│  - Conversations│     │  - Conversations│     │                 │
+│  - Preferences  │     │  - Preferences  │     │  - Product docs │
+│  - Past issues  │     │  - Past issues  │     │  - FAQs         │
+│  - Solutions    │     │  - Solutions    │     │  - Guides       │
+└────────┬────────┘     └────────┬────────┘     └────────┬────────┘
+         │                       │                       │
+         └───────────────────────┴───────────────────────┘
+                                 │
+                           Agent queries
+                           multiple banks
+```
+
+**Key benefits:**
+- Product docs indexed once, shared by all users
+- User memory is 100% isolated
+- Simple mental model, no complex filtering
+
+## Implementation
+
+### 1. Set Up Memory Banks
+
+Create three types of banks:
+
+```python
+from hindsight import HindsightClient
+
+client = HindsightClient()
+
+# Shared knowledge bank (created once)
+shared_bank = client.create_bank(
+    bank_id="product-docs",
+    name="Product Documentation"
+)
+
+# Per-user banks (created when user signs up)
+def create_user_bank(user_id: str):
+    return client.create_bank(
+        bank_id=f"user-{user_id}",
+        name=f"Memory for {user_id}"
+    )
+```
+
+### 2. Index Product Documentation
+
+Index your product docs into the shared bank (do this once, or on doc updates):
+
+```python
+# Index product documentation
+client.retain(
+    bank_id="product-docs",
+    content=[
+        {
+            "role": "document",
+            "content": "# Pricing Tiers\n\nBasic: $10/mo...",
+            "metadata": {"source": "pricing.md"}
+        },
+        {
+            "role": "document",
+            "content": "# Getting Started\n\nTo set up...",
+            "metadata": {"source": "quickstart.md"}
+        }
+    ]
+)
+```
+
+### 3. Store User Conversations
+
+After each support interaction, retain it in the user's bank:
+
+```python
+def save_conversation(user_id: str, messages: list):
+    client.retain(
+        bank_id=f"user-{user_id}",
+        content=messages  # [{"role": "user", "content": "..."}, ...]
+    )
+```
+
+### 4. Query Multiple Banks at Support Time
+
+When handling a user query, retrieve context from both banks:
+
+```python
+async def get_support_context(user_id: str, query: str):
+    # Get user's personal context
+    user_context = await client.recall(
+        bank_id=f"user-{user_id}",
+        query=query
+    )
+
+    # Get relevant product documentation
+    docs_context = await client.recall(
+        bank_id="product-docs",
+        query=query
+    )
+
+    return {
+        "user_history": user_context.results,
+        "documentation": docs_context.results
+    }
+```
+
+### 5. Build the Agent Prompt
+
+Combine both contexts in your agent's prompt:
+
+```python
+def build_prompt(query: str, context: dict) -> str:
+    return f"""You are a helpful support agent.
+
+## User's History
+{format_results(context["user_history"])}
+
+## Product Documentation
+{format_results(context["documentation"])}
+
+## Current Question
+{query}
+
+Use the user's history to personalize your response and the documentation
+for accurate product information. If you find a solution, remember it for
+future reference.
+"""
+```
+
+## Promoting Learnings to Shared Knowledge
+
+When the agent discovers a solution that's not in the docs, you can optionally promote it to a "learnings" bank:
+
+```

+                           all three banks
+```
+
+```python

+            "metadata": {"type": "verified_solution"}
+        }]
+    )
+```
+
+Then query three banks: user + docs + learnings.
+
+## Complete Example
+
+```python
+from hindsight import HindsightClient
+
+client = HindsightClient()
+
+async def handle_support_request(user_id: str, query: str):
+    # 1. Recall from user's memory
+    user_recall = await client.recall(
+        bank_id=f"user-{user_id}",
+        query=query
+    )
+
+    # 2. Recall from shared docs
+    docs_recall = await client.recall(
+        bank_id="product-docs",
+        query=query
+    )
+
+    # 3. Recall from learnings (optional)
+    learnings_recall = await client.recall(
+        bank_id="support-learnings",
+        query=query
+    )
+
+    # 4. Build context for LLM
+    context = f"""
+User History:
+{format_results(user_recall.results)}
+
+Product Docs:
+{format_results(docs_recall.results)}
+
+Known Solutions:
+{format_results(learnings_recall.results)}
+"""
+
+    # 5. Generate response with your LLM
+    response = await llm.complete(
+        system="You are a support agent...",
+        context=context,
+        query=query
+    )
+
+    # 6. Save the conversation to user's memory
+    await client.retain(
+        bank_id=f"user-{user_id}",
+        content=[
+            {"role": "user", "content": query},
+            {"role": "assistant", "content": response}
+        ]
+    )
+
+    return response
+```
+
+## When to Use This Pattern
+
+**Good fit:**
+- Support agents with shared documentation
+- Multi-tenant applications with shared reference data
+- Any scenario needing user isolation + shared knowledge
+
+**Consider alternatives if:**
+- You need cross-user learning (users benefiting from other users' solutions)
+- Entity relationships must span across users and docs

-# RAG vs Hindsight: Why Your AI Needs Real Memory
+# RAG vs Memory
 
-Traditional RAG (Retrieval-Augmented Generation) finds documents similar to your query. Hindsight gives your AI actual memory—with temporal reasoning, entity understanding, and evolving beliefs.
+Traditional RAG (Retrieval-Augmented Generation) retrieves documents similar to a query. Hindsight provides structured memory with temporal reasoning, entity understanding, and belief formation.
 
-Here's what that difference looks like in practice.
-
----
-
-## Example 1: Multi-Hop Reasoning
-
-**Scenario:** Your AI assistant has learned these facts over time:
-- "Alice is the tech lead on Project Atlas"
-- "Project Atlas uses Kubernetes for deployment"
-- "The Kubernetes cluster had an outage last Tuesday"
-
-**User asks:** "Was Alice affected by any recent issues?"
-
-### RAG Response
-> I found information about Alice being a tech lead, but I don't have specific information about recent issues affecting her.
-
-**Why it fails:** RAG only finds facts semantically similar to "Alice" + "recent issues". It can't connect Alice → Project Atlas → Kubernetes → outage because those facts exist in different semantic spaces.
-
-### Hindsight Response
-> Yes, Alice was likely affected. She's the tech lead on Project Atlas, which uses Kubernetes for deployment. The Kubernetes cluster had an outage last Tuesday, which would have impacted her team's deployments.
-
-**Why it works:** Hindsight's knowledge graph links Alice → Project Atlas → Kubernetes → outage through entity relationships. Graph traversal discovers the connection even though no single fact mentions both Alice and the outage.
-
----
-
-## Example 2: Temporal Reasoning
-
-**Scenario:** An AI assistant has accumulated months of conversation history:
-- March: "Alice started the migration to microservices"
-- April: "Alice completed the authentication service"
-- May: "Alice presented the architecture review"
-- October: "Alice is now focusing on performance optimization"
-
-**User asks:** "What did Alice accomplish last spring?"
-
-### RAG Response
-> Alice has worked on microservices migration, authentication service, architecture review, and performance optimization.
-
-**Why it fails:** RAG treats "last spring" as keywords, returning ALL mentions of Alice regardless of when they occurred. No temporal filtering.
-
-### Hindsight Response
-> Last spring (March-May), Alice started the migration to microservices, completed the authentication service, and presented the architecture review. She's since moved on to performance optimization.
-
-**Why it works:** Hindsight parses "last spring" into a date range (March-May), then retrieves only facts with timestamps in that window. The temporal-graph strategy ensures historical queries return chronologically accurate results.
-
----
-
-## Example 3: Consistent Personality
-
-**Scenario:** Two AI assistants have the same facts about remote work:
-- "Remote work saves 1 hour of commute daily"
-- "65% of employees report higher productivity"
-- "Some teams report communication challenges"
-- "Office presence improves spontaneous collaboration"
-
-**User asks:** "Should our company adopt remote work?"
-
-### RAG Response (varies each time)
-> Remote work has benefits like saved commute time and higher productivity, but also challenges like communication issues. Consider your team's needs.
-
-**Why it fails:** Generic, fence-sitting response. No consistent perspective. Ask again tomorrow, get a slightly different answer.
-
-### Hindsight Response (Conservative assistant, high conscientiousness)
-> While the productivity data is encouraging, I'd recommend a cautious approach. The communication challenges and reduced spontaneous collaboration could impact team cohesion long-term. Consider a hybrid model that maintains some office presence for important collaborative work.
-
-### Hindsight Response (Innovative assistant, high openness)
-> The data strongly supports remote work—65% productivity gains and an hour saved daily per employee. Communication challenges are solvable with the right tools. I'd embrace this as an opportunity to modernize how the team works.
-
-**Why it works:** Each Hindsight bank has a personality (Big Five traits) that shapes how it interprets facts. Same data, consistent but different perspectives. The assistant develops opinions that persist and evolve over time.
-
----
-
-## Example 4: Evolving Beliefs
-
-**Scenario:** An AI coding assistant forms opinions based on experience.
-
-**Week 1:**
-```python
-retain("User struggled with Python async/await syntax")
-retain("User successfully implemented the feature using threads")
-```
-*Assistant forms opinion:* "User prefers synchronous Python patterns" (confidence: 0.7)
-
-**Week 3:**
-```python
-retain("User asked about asyncio best practices")
-retain("User implemented async database calls successfully")
-```
-*Opinion updated:* "User is growing comfortable with async patterns" (confidence: 0.6)
-
-**User asks:** "Should I use async for this new API endpoint?"
-
-### RAG Response
-> Async can improve performance for I/O-bound operations. Here's how to implement it...
-
-**Why it fails:** No memory of user's journey. Same generic advice given to everyone.
-
-### Hindsight Response
-> Given your recent success with async database calls, I'd recommend async for this endpoint too. You've gotten comfortable with the patterns—this is a good opportunity to apply them. Want me to show an approach similar to what worked in your database implementation?
-
-**Why it works:** Hindsight tracked the user's evolving skill with async Python. Its opinion (with confidence score) updated as new evidence arrived. The response reflects accumulated understanding of this specific user's journey.
-
----
-
-## Example 5: Entity Understanding
-
-**Scenario:** A customer support AI learns about a user over multiple sessions:
-- Session 1: "I'm having trouble with my Pro subscription"
-- Session 2: "The mobile app crashes when I open settings"
-- Session 3: "I switched to annual billing last month"
-- Session 4: "The desktop app is working fine"
-
-**User asks:** "What do you know about my account?"
-
-### RAG Response
-> You've mentioned issues with Pro subscription, mobile app crashes in settings, switching to annual billing, and the desktop app working fine.
-
-**Why it fails:** Returns disconnected facts in no particular structure. No synthesized understanding.
-
-### Hindsight Response
-> You're on a Pro subscription with annual billing (switched last month). You've experienced some mobile app issues—specifically crashes in the settings menu—though your desktop app has been working fine. Would you like help troubleshooting the mobile app crashes?
-
-**Why it works:** Hindsight automatically generates "observations"—synthesized summaries of entities (in this case, the user). Instead of listing disconnected facts, it presents a coherent picture and proactively offers relevant help.
-
----
-
-## Example 6: Connecting Conversations Across Time
-
-**Scenario:** A personal AI assistant has had conversations over several months:
-- January: "I'm thinking about learning guitar"
-- February: "I bought a used acoustic guitar"
-- March: "Practice is going well, learning basic chords"
-- June: "Work has been crazy, no time for hobbies"
-- September: "Feeling burned out, need something relaxing"
-
-**User asks:** "What should I do to unwind this weekend?"
-
-### RAG Response
-> Here are some popular relaxation activities: meditation, reading, nature walks, or picking up a creative hobby.
-
-**Why it fails:** Generic suggestions. No awareness of the user's existing interests or history.
-
-### Hindsight Response
-> You mentioned feeling burned out—have you picked up the guitar lately? You were making good progress with chords back in March before work got busy. Music could be a good way to unwind, and you already have the guitar.
-
-**Why it works:** Hindsight connects the burnout complaint to the dormant hobby through entity and temporal reasoning. It remembers the user's journey: interest → purchase → progress → life interruption, and surfaces relevant context at the right moment.
-
----
-
-## The Technical Difference
-
-### How RAG Works
-```
-Query → Embed → Find similar vectors → Return top-k chunks
-```
-- One search strategy (semantic similarity)
-- No entity linking
-- No temporal understanding
-- No persistent beliefs
-- Stateless between queries
-
-### How Hindsight Works
-```
-Query → Parse temporal expressions → Execute 4 parallel strategies:
-  • Semantic search (like RAG)
-  • Keyword search (catches exact names)
-  • Graph traversal (entity/causal connections)
-  • Temporal-graph (time-filtered relationships)
-→ Fuse results → Rerank → Apply personality → Generate response
-```
-- Four complementary search strategies
-- Knowledge graph with entity/temporal/causal links
-- Temporal parsing and filtering
-- Opinion formation and evolution
-- Consistent personality across sessions

+## Example Scenarios
+
+### Multi-Hop Reasoning
+
+**Stored facts:**
+- "Alice is the tech lead on Project Atlas"
+- "Project Atlas uses Kubernetes"
+- "Kubernetes cluster had an outage Tuesday"
+
+**Query:** "Was Alice affected by recent issues?"
+
+| System | Result |
+|--------|--------|
+| RAG | Retrieves facts about Alice only (no semantic similarity to "issues") |
+| Hindsight | Traverses Alice → Project Atlas → Kubernetes → outage via entity links |
+
+### Temporal Queries
+
+**Stored facts with timestamps:**
+- March: "Alice started microservices migration"
+- April: "Alice completed auth service"
+- October: "Alice focusing on performance"
+
+**Query:** "What did Alice do last spring?"
+
+| System | Result |
+|--------|--------|
+| RAG | Returns all Alice facts regardless of date |
+| Hindsight | Parses "last spring" → March-May, filters to that range |
+
+### Entity Understanding
+
+**Stored facts about a user across sessions:**
+- "Pro subscription"
+- "Mobile app crashes in settings"
+- "Switched to annual billing"
+- "Desktop app working fine"
+
+**Query:** "What do you know about my account?"
+
+| System | Result |
+|--------|--------|
+| RAG | Lists disconnected facts |
+| Hindsight | Returns synthesized entity observations: subscription status, billing, known issues |
+
+### Belief Evolution
+
+**Week 1:** User struggles with async Python, succeeds with threads
+**Week 3:** User asks about asyncio, implements async database calls
+
+| System | Behavior |
+|--------|----------|

+# Storage
+
+Hindsight uses PostgreSQL as its sole storage backend.
+
+## Why PostgreSQL?
+
+PostgreSQL provides all capabilities required for a semantic memory system in a single database:
+
+| Capability | Implementation |
+|------------|----------------|
+| Vector search | pgvector extension with HNSW indexes |
+| Full-text search | Built-in tsvector with GIN indexes |
+| Relational data | Native PostgreSQL |
+| JSON documents | JSONB with indexing |
+| Graph queries | Recursive CTEs |
+
+### Reduced System Dependencies
+
+Building exclusively for PostgreSQL simplifies deployment and operations:
+
+- Single connection string to configure
+- Single backup and restore strategy
+- Single monitoring target
+- ACID transactions across all data types
+- Single upgrade path
+
+### No Storage Abstraction
+
+Hindsight does not abstract storage behind a generic interface. This is a deliberate trade-off.
+
+We believe PostgreSQL is becoming the standard database API. Its popularity, extension ecosystem, and modularity mean that PostgreSQL-compatible interfaces are appearing everywhere—from serverless offerings to distributed databases. Building for PostgreSQL today means compatibility with a growing ecosystem tomorrow.
+
+Supporting multiple databases would increase flexibility but conflict with our core goals: Hindsight is fully open source and designed to be as simple as possible to run and use. Adding database abstractions introduces complexity in code, testing, documentation, and operations—complexity that we pass on to users.
+
+By committing to PostgreSQL, we keep the system simple:
+- One set of deployment instructions
+- One set of performance characteristics to understand
+- One codebase optimized for one backend
+- No configuration decisions about which database to use
+
+## Development with pg0
+
+For local development, Hindsight uses **[pg0](https://github.com/vectorize-io/pg0)**—an embedded PostgreSQL distribution.
+
+### What is pg0?
+
+pg0 is a single binary containing:
+- PostgreSQL server
+- pgvector extension (pre-installed)
+- Automatic initialization
+
+### Behavior
+
+When no `DATABASE_URL` is configured, Hindsight:
+1. Downloads the pg0 binary for the current platform (macOS ARM, Linux x86_64/ARM64, Windows)
+2. Starts an embedded PostgreSQL instance on port 5555
+3. Initializes the schema
+4. Stores data in `~/.hindsight/pg0/`
+
+### Environments
+
+| Environment | Database | Configuration |
+|-------------|----------|---------------|
+| Development | pg0 (embedded) | Automatic |
+| Production | PostgreSQL 15+ | `DATABASE_URL` environment variable |
+
+## Requirements
+
+- PostgreSQL 15 or later
+- pgvector 0.5.0 or later
+
+Any PostgreSQL instance that satisfies these requirements should work. If you encounter issues with a specific setup, [open a GitHub issue](https://github.com/hindsight-ai/hindsight/issues).
+
+### Tested Managed Services
+
+- AWS RDS (PostgreSQL 15+)
+- Google Cloud SQL
+- Azure Database for PostgreSQL
+- Supabase
+- Neon
