* feat: introduce hindsight-api-slim and hindsight-all-slim packages

Closes #552

- Move all source code from hindsight-api/ to new hindsight-api-slim/
- hindsight-api-slim has heavy ML deps (torch, sentence-transformers,
  transformers, einops, flashrank, mlx, mlx-lm, safetensors) and
  pg0-embedded as optional extras: [local-ml], [embedded-db], [all]
- hindsight-api becomes a zero-code meta-package depending on
  hindsight-api-slim[all] for full backward compatibility
- Add hindsight-all-slim meta-package: hindsight-api-slim + client + embed
- hindsight-all updated to depend on hindsight-api-slim[all]
- pg0.py: lazy-import pg0 with clear ImportError pointing to [embedded-db]
- Dockerfile: replace sed hack with proper uv sync --extra flags
- Update release.yml, test.yml, lint.sh, release.sh, CLAUDE.md and
  all path references throughout the repo

* refactor: rename hindsight/ directory to hindsight-all/

* docs: document hindsight-api-slim and hindsight-all-slim package variants

Add package variants table and extras explanation to installation.md

* docs: remove emojis from installation.md, use professional tone

* docs: link Docker slim variant to pip package variants section

* docs: consolidate Docker image variants into single table

* ci: fix working-directory paths after package restructure

- Replace all hindsight-api → hindsight-api-slim in test.yml
- Replace hindsight → hindsight-all in test.yml
- Add --extra embedded-db to test-embed API install step

* ci: add local-ml and embedded-db extras to API sync steps

These extras were previously implicit in the old hindsight-api package
(which bundled everything). Now that hindsight-api-slim uses optional
extras, we must explicitly request local-ml and embedded-db in CI.

* ci: add API install step with embedded-db to test-embed smoke test

The smoke test starts hindsight-api as a daemon, which requires pg0-embedded.
Add a dedicated install step for hindsight-api-slim with embedded-db extra
so the daemon can start successfully.

* ci: remove --no-install-project when using optional extras

When --no-install-project is combined with --extra, the optional deps
are not installed because extras require the project to be active.
Remove --no-install-project from steps that need local-ml or embedded-db.

* ci: fix ordering of uv sync steps to preserve optional extras

When uv sync runs for a different workspace member, it removes optional
extras installed for other members. Fix by always running extra-requiring
API sync last, after other workspace member syncs.

Also remove --no-install-project from embedded-db sync in test-embed,
as --no-install-project prevents optional extras from being active.

* ci: add local-ml extra to test-embed API install for smoke test

The smoke test starts the full API server which needs sentence-transformers
for local embeddings (default provider). Add local-ml extra to the install.

* ci: simplify extras with --all-extras and add slim pip smoke test

- Replace explicit --extra local-ml --extra embedded-db with --all-extras
  for cleaner, more maintainable sync steps
- Add test-pip-slim job: tests hindsight-api-slim[embedded-db] without
  local ML models, using Cohere for embeddings/reranking (mirrors Docker
  slim smoke test approach)

* ci: simplify slim smoke test to health check only (mirrors Docker test)

+    llm_model="openai/gpt-oss-120b"
+)
+
+# Create client
+client = HindsightClient(base_url=server.url)
+
+# Store memories
+client.put(agent_id="assistant", content="User prefers Python for data analysis")
+
+# Search memories
+results = client.search(agent_id="assistant", query="programming preferences")
+
+# Generate contextual response
+response = client.think(agent_id="assistant", query="What languages should I recommend?")

+# Hindsight API
+
+**Memory System for AI Agents** — Temporal + Semantic + Entity Memory Architecture using PostgreSQL with pgvector.
+
+Hindsight gives AI agents persistent memory that works like human memory: it stores facts, tracks entities and relationships, handles temporal reasoning ("what happened last spring?"), and forms opinions based on configurable disposition traits.
+
+## Installation
+
+```bash
+pip install hindsight-api
+```
+
+## Quick Start
+
+### Run the Server
+
+```bash
+# Set your LLM provider
+export HINDSIGHT_API_LLM_PROVIDER=openai
+export HINDSIGHT_API_LLM_API_KEY=sk-xxxxxxxxxxxx
+
+# Start the server (uses embedded PostgreSQL by default)
+hindsight-api
+```
+
+The server starts at http://localhost:8888 with:
+- REST API for memory operations
+- MCP server at `/mcp` for tool-use integration
+
+### Use the Python API
+
+```python
+from hindsight_api import MemoryEngine
+
+# Create and initialize the memory engine
+memory = MemoryEngine()
+await memory.initialize()
+
+# Create a memory bank for your agent
+bank = await memory.create_memory_bank(
+    name="my-assistant",
+    background="A helpful coding assistant"
+)
+
+# Store a memory
+await memory.retain(
+    memory_bank_id=bank.id,
+    content="The user prefers Python for data science projects"
+)
+
+# Recall memories
+results = await memory.recall(
+    memory_bank_id=bank.id,
+    query="What programming language does the user prefer?"
+)
+
+# Reflect with reasoning
+response = await memory.reflect(
+    memory_bank_id=bank.id,
+    query="Should I recommend Python or R for this ML project?"
+)
+```
+
+## CLI Options
+
+```bash
+hindsight-api --help
+
+# Common options
+hindsight-api --port 9000          # Custom port (default: 8888)
+hindsight-api --host 127.0.0.1     # Bind to localhost only
+hindsight-api --workers 4          # Multiple worker processes
+hindsight-api --log-level debug    # Verbose logging
+```
+
+## Configuration
+
+Configure via environment variables:
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `HINDSIGHT_API_DATABASE_URL` | PostgreSQL connection string | `pg0` (embedded) |
+| `HINDSIGHT_API_LLM_PROVIDER` | `openai`, `anthropic`, `gemini`, `groq`, `ollama`, `lmstudio` | `openai` |
+| `HINDSIGHT_API_LLM_API_KEY` | API key for LLM provider | - |
+| `HINDSIGHT_API_LLM_MODEL` | Model name | `gpt-4o-mini` |
+| `HINDSIGHT_API_HOST` | Server bind address | `0.0.0.0` |
+| `HINDSIGHT_API_PORT` | Server port | `8888` |
+
+### Example with External PostgreSQL
+
+```bash
+export HINDSIGHT_API_DATABASE_URL=postgresql://user:pass@localhost:5432/hindsight
+export HINDSIGHT_API_LLM_PROVIDER=groq
+export HINDSIGHT_API_LLM_API_KEY=gsk_xxxxxxxxxxxx
+
+hindsight-api
+```
+
+## Docker
+
+```bash
+docker run --rm -it -p 8888:8888 \
+  -e HINDSIGHT_API_LLM_API_KEY=$OPENAI_API_KEY \
+  -v $HOME/.hindsight-docker:/home/hindsight/.pg0 \
+  ghcr.io/vectorize-io/hindsight:latest
+```
+
+## MCP Server
+
+For local MCP integration without running the full API server:
+
+```bash
+hindsight-local-mcp
+```
+
+This runs a stdio-based MCP server that can be used directly with MCP-compatible clients.
+
+## Key Features
+
+- **Multi-Strategy Retrieval (TEMPR)** — Semantic, keyword, graph, and temporal search combined with RRF fusion
+- **Entity Graph** — Automatic entity extraction and relationship tracking
+- **Temporal Reasoning** — Native support for time-based queries
+- **Disposition Traits** — Configurable skepticism, literalism, and empathy influence opinion formation
+- **Three Memory Types** — World facts, bank actions, and formed opinions with confidence scores
+

-Hindsight requires PostgreSQL with the **pgvector** extension for vector similarity search.
+Hindsight requires PostgreSQL 14+ with a vector extension for similarity search. The supported extensions are:
+
+- **pgvector** (default)
+- **pgvectorscale**
+- **vchord**
+
+Configure which one to use with `HINDSIGHT_API_VECTOR_EXTENSION`. See [Configuration](./configuration) for details.
 
 **By default**, Hindsight uses **pg0** — an embedded PostgreSQL that runs locally on your machine. This is convenient for development but **not recommended for production**.

 ### LLM Provider
 
-You need an LLM API key for fact extraction, entity resolution, and answer generation:
-
-- **Groq** (recommended): Fast inference with `gpt-oss-20b`
-- **OpenAI**: GPT-4o, GPT-4o-mini
-- **Ollama**: Run models locally
-
-See [Models](./models) for detailed comparison and configuration.

 ### Docker Image Variants
 
-Hindsight provides two image variants with different size/capability tradeoffs:
+| Variant | Size (AMD64) | Size (ARM64) | When to use |
+|---------|--------------|--------------|-------------|
+| **Full** (`latest`) | ~9 GB | ~3.7 GB | Default. Works out of the box with no external services except the LLM. |
+| **Slim** (`slim`) | ~500 MB | ~500 MB | Use when you already rely on external services for embeddings and reranking (OpenAI, Cohere, TEI). Significantly smaller image, faster deploys. Requires [external providers](./configuration#embeddings). |
 
-| Variant | Size (AMD64) | Size (ARM64) | Use Case |
-|---------|--------------|--------------|----------|
-| **Full** (`latest`) | ~9 GB | ~3.7 GB | Includes local ML models (embeddings, reranking) |
-| **Slim** (`slim`) | ~500 MB | ~500 MB | Requires external embedding/reranking providers |
-
-**Full image** (default):
-```bash
-docker run --rm -it -p 8888:8888 \
-  -e HINDSIGHT_API_LLM_API_KEY=$OPENAI_API_KEY \
-  ghcr.io/vectorize-io/hindsight:latest
-```
-- ✅ Works out of the box with local ML models
-- ✅ No additional services needed
-- ❌ Larger image size (AMD64 includes CUDA libraries for GPU support)
-
-**Slim image**:
-```bash
-docker run --rm -it -p 8888:8888 \
-  -e HINDSIGHT_API_LLM_API_KEY=$OPENAI_API_KEY \
-  -e HINDSIGHT_API_EMBEDDINGS_PROVIDER=openai \
-  -e HINDSIGHT_API_RERANKER_PROVIDER=cohere \
-  -e HINDSIGHT_API_COHERE_API_KEY=$COHERE_API_KEY \
-  ghcr.io/vectorize-io/hindsight:latest-slim
-```
-- ✅ Dramatically smaller image (~95% reduction on AMD64)
-- ✅ Faster pull/deploy times
-- ✅ Lower memory footprint
-- ❌ Requires external embedding/reranking services (OpenAI, Cohere, TEI)
-
-**When to use slim:**
-- Cloud deployments where image size matters
-- Using managed embedding services (OpenAI, Cohere)
-- Running on Text Embeddings Inference (TEI) infrastructure
-- Kubernetes environments with fast pull requirements
-
-:::warning Slim Image Requires External Providers
-If you run the slim image **without** setting external embedding providers, you'll see this error:
-
-```
-ImportError: sentence-transformers is required for LocalSTEmbeddings.
-Install it with: pip install sentence-transformers
-```
-
-**Fix:** Always set embedding and reranking providers when using slim images:
-```bash
--e HINDSIGHT_API_EMBEDDINGS_PROVIDER=openai
--e HINDSIGHT_API_EMBEDDINGS_OPENAI_API_KEY=sk-xxx
--e HINDSIGHT_API_RERANKER_PROVIDER=cohere
--e HINDSIGHT_API_COHERE_API_KEY=xxx
-```
-:::
-
-See [Configuration](./configuration#embeddings) for all embedding provider options.
+The slim image corresponds to the [`hindsight-api-slim`](#package-variants) pip package. See [Configuration](./configuration#embeddings) for external provider options.

+## Embedded in a Python Application
+
+**Best for**: Using Hindsight programmatically from Python without running a separate server process.
+
+```bash
+pip install hindsight-all        # Full — works out of the box
+pip install hindsight-all-slim   # Slim — requires external services for embeddings, reranking, and the database
+```
+
+`hindsight-all` supports two modes of embedding:
+
+**In-process** (`HindsightServer`): the server runs in a background thread inside your application. Best when you want the tightest integration and are already managing your own process lifecycle.
+
+```python
+from hindsight import HindsightServer, HindsightClient
+
+with HindsightServer(llm_provider="openai", llm_api_key="sk-xxx") as server:
+    client = HindsightClient(base_url=server.url)
+    client.retain(bank_id="alice", content="Alice prefers concise answers.")
+    results = client.recall(bank_id="alice", query="How should I respond to Alice?")
+```
+
+**Managed subprocess** (`HindsightEmbedded`): the server runs as a background daemon process, shared across multiple Python processes or sessions. The daemon starts on first use and shuts down automatically after an idle timeout.
+
+```python
+from hindsight import HindsightEmbedded
+
+client = HindsightEmbedded(llm_provider="openai", llm_api_key="sk-xxx")
+client.retain(bank_id="alice", content="Alice prefers concise answers.")
+results = client.recall(bank_id="alice", query="How should I respond to Alice?")
+```
+
+See the [Python SDK](../sdks/python.md) for the full API reference.
