### Adding New API Configuration Flags
Configuration follows a hierarchical system: **Global (env vars) → Tenant (via extension) → Bank (database)**.
When adding a new environment variable configuration:
Fields must be categorized as either **hierarchical** (can be overridden per-tenant/bank) or **static** (server-level only).
#### Adding a New Configuration Field
1. **config.py** (`hindsight-api-slim/hindsight_api/config.py`):
- Add `ENV_*` constant for the environment variable name (e.g., `ENV_MY_SETTING = "HINDSIGHT_API_MY_SETTING"`)
1. **config.py** (`hindsight-api/hindsight_api/config.py`):
- Add `ENV_*` constant for the environment variable name
- Add `DEFAULT_*` constant for the default value
- Add field to `HindsightConfig` dataclass with type annotation
- **Mark as hierarchical or static** by adding to `_HIERARCHICAL_FIELDS` set (hierarchical) or leaving it out (static)
- Add field to `HindsightConfig` dataclass
- Add initialization in `from_env()` method
```python
# Hierarchical field (can be overridden per-bank)
_HIERARCHICAL_FIELDS = {
...,
"my_setting", # Add here for hierarchical
}
# Static field - just don't add to _HIERARCHICAL_FIELDS
```
2. **main.py** (`hindsight-api-slim/hindsight_api/main.py`):
2. **main.py** (`hindsight-api/hindsight_api/main.py`):
- Add field to the manual `HindsightConfig()` constructor call (search for "CLI override")
3. **Use hierarchical config in MemoryEngine**:
```python
# Config is resolved automatically per bank via ConfigResolver
config_dict = await self._config_resolver.get_bank_config(bank_id, context)
value = config_dict["my_setting"]
```
4. **Use static config** (non-hierarchical):
3. **Use the config** in code:
```python
from ...config import get_config
config = get_config()
value = config.my_static_field
value = config.your_new_field
```
5. **Documentation** (`hindsight-docs/docs/developer/configuration.md`):
4. **Documentation** (`hindsight-docs/docs/developer/configuration.md`):
- Add to appropriate section table with Variable, Description, Default
- Mark if it's hierarchical (can be overridden per-bank)
#### Hierarchical vs Static Guidelines
**Hierarchical** (per-bank overridable):
- LLM settings (provider, model, API key, base URL)
- Operation-specific settings (retain mode, chunk size, etc.)
- Feature flags that vary by customer/bank
**Static** (server-level only):
- Infrastructure settings (database URL, port, host)
- Global limits (max concurrent operations)
- System-wide feature flags

## Release Process
The project uses `scripts/release.sh` for creating releases. This script automates the entire release workflow:
1. Bumps version in all components (API, clients, CLI, control plane, Helm)
2. **Regenerates OpenAPI spec and client SDKs** (Python, TypeScript, Rust)
3. Updates documentation versioning
4. Creates a commit and git tag
5. Pushes to GitHub (triggers CI/CD to publish packages)
### Usage
```bash
./scripts/release.sh <version>
```
**Example:**
```bash
./scripts/release.sh 0.5.0
```
### Important for Developers
- During development, version bumps in `__init__.py` do NOT require client regeneration
- Clients are only regenerated during releases
- Do not manually run `./scripts/generate-clients.sh` unless testing generation changes
- Client version comments will reflect the API version from the latest release

## What is Hindsight?
Hindsight™ is an agent memory system built to create smarter agents that learn over time. Most agent memory systems focus on recalling conversation history. Hindsight is focused on making agents that learn, not just remember.
Hindsight™ is an agent memory system built to create smarter agents that learn over time. It eliminates the shortcomings of alternative techniques such as RAG and knowledge graph and delivers state-of-the-art performance on long term memory tasks.
Hindsight addresses common challenges that have frustrated AI engineers building agents to automate tasks and assist users with conversational interfaces. Many of these challenges stem directly from a lack of memory.
<video src="https://github.com/user-attachments/assets/923b798d-3581-4897-bb62-9cfa5a931682" controls></video>
- **Inconsistency:** Agents complete tasks successfully one time, then fail when asked to complete the same task again. Memory gives the agent a mechanism to remember what worked and what didn't and to use that information to reduce errors and improve consistency.
- **Hallucinations:** Long term memory can be seeded with external knowledge to ground agent behavior in reliable sources to augment training data.
- **Cognitive Overload:** As workflows get complex, retrievals, tool calls, user messages and agent responses can grow to fill the context window leading to context rot. Short term memory optimization allows agents to reduce tokens and focus context by removing irrelevant details.
It eliminates the shortcomings of alternative techniques such as RAG and knowledge graph and delivers state-of-the-art performance on long term memory tasks.
## How is Hindsight Different From Other Memory Systems?
![Overview](./hindsight-docs/static/img/hindsight-overview.webp)
Most agent memory implementation rely on basic vector search or sometimes use a knowledge graph. Hindsight uses biomimetic data structures to organize agent memories in a way that is more like how human memory works:
- **World:** Facts about the world ("The stove gets hot")
- **Experiences:** Agent's own experiences ("I touched the stove and it really hurt")
- **Opinion:** Beliefs with confidence scores ("I shouldn't touch the stove again" - .99 confidence)
- **Observation:** Complex mental models derived by reflecting on facts and experiences ("Curling irons, ovens, and fire are also hot. I shouldn't touch those either.")
Memories in Hindsight are stored in banks (i.e. memory banks). When memories are added to Hindsight, they are pushed into either the world facts or experiences memory pathway. They are then represented as a combination of entities, relationships, and time series with sparse/dense vector representations to aid in later recall.
Hindsight provides three simple methods to interact with the system:
- **Retain:** Provide information to Hindsight that you want it to remember
- **Recall:** Retrieve memories from Hindsight
- **Reflect:** Reflect on memories and experiences to generate new observations and insights from existing memories.
### Agent Memory That Learns
A key goal of Hindsight is to build agent memory that enables agents to learn and improve over time. This is the role of the `reflect` operation which provides the agent to form broader opinions and observations over time.
For example, imagine a product support agent that is helping a user troubleshoot a problem. It uses a `search-documentation` tool it found on an MCP server. Later in the conversation, the agent discovers that the documentation returned from the tool wasn't for the product the user was asking about. The agent now has an experience in its memory bank. And just like humans, we want that agent to learn from its experience.
As the agent gains more experiences, `reflect` allows the agent to form observations about what worked, what didn't, and what to do differently the next time it encounters a similar task.

Hindsight is being used in production at Fortune 500 enterprises and by a growing number of AI startups.
## Adding Hindsight to Your AI Agents
The easiest way to use Hindsight with an existing agent is with the LLM Wrapper. You can add memory to your agent with 2 lines of code. That will swap your current LLM client out with the Hindsight wrapper. After that, memories will be stored and retrieved automatically as you make LLM calls.
If you need more control over how and when your agent stores and recalls memories, there's also a simple API you can integrate with using the SDKs or directly via HTTP.

Hindsight is built to support conversational AI agents as well as agents that are intended to perform tasks autonomously. The ideal use case for Hindsight are agents that require a blend of these features such as AI employees that need to handle open-ended tasks, change behavior based on user feedback, and learn to perform complex tasks to automate work at a level that approximates a human work. Hindsight can be used with simple AI workflows like those built with n8n and other similar tools, but may be overkill for such applications.
### Per-User Memories and Chat History
One of the simpler use cases you can use Hindsight for is to personalize AI chatbots and other conversational agents by storing and recalling memories associated with individual users.
The requirements for this use case usually look something like this:
![Per-User Memories](./hindsight-docs/static/img/per-user-memory-requirements.png)
<video src="https://github.com/user-attachments/assets/4805e8e1-e7d1-47c6-a4f8-2344a5ec8906" controls></video>
Satisfying these requirements in Hindsight is straightforward. When new user inputs and tool calls are ingested into Hindsight using the retain operation, custom metadata can be used to enrich the new memories. Metadata provides a convenient way to isolate memories that need to be restricted to a given user. Once these are fed into the retain operation, any raw memories and mental models that get created can be filtered when retrieving relevant memories.
![Per-User Memories](./hindsight-docs/static/img/per-user-memory-howto.png)
await client.retain('my-bank', 'Alice loves hiking in Yosemite');
await client.recall('my-bank', 'What does Alice like?');

# Nginx Reverse Proxy with Custom Base Path
Deploy Hindsight API under `/hindsight` (or any custom path) using Nginx reverse proxy.
## Quick Start (Published Image - API Only)
```bash
docker-compose up
```
- **API:** http://localhost:8080/hindsight/docs
- **Control Plane:** http://localhost:9999 (direct access, not proxied)
## Full Stack with Custom Base Path (Requires Build)
**Important:** You cannot rebuild from the published image with build args. You must build from source.
### Build from Source with Custom Base Path
1. **Clone the repository** (if you haven't):
```bash
git clone https://github.com/vectorize-io/hindsight.git
cd hindsight
```
2. **Build with base path**:
```bash
docker build \
--build-arg NEXT_PUBLIC_BASE_PATH=/hindsight \
-f docker/standalone/Dockerfile \
-t hindsight:custom \
.
```
3. **Update docker-compose.yml** to use your built image:
```yaml
services:
hindsight:
image: hindsight:custom # ← Change this
environment:
HINDSIGHT_API_BASE_PATH: /hindsight
NEXT_PUBLIC_BASE_PATH: /hindsight
```
4. **Update nginx.conf** to handle Control Plane routes (see below)
5. **Run**:
```bash
docker-compose up
```
### Required nginx.conf for Full Stack
Replace the current `nginx.conf` with this to proxy both API and Control Plane:
```nginx
events { worker_connections 1024; }
http {
include /etc/nginx/mime.types;
default_type application/octet-stream;
upstream hindsight_api { server hindsight:8888; }
upstream hindsight_cp { server hindsight:9999; }
server {
listen 80;
# API
location ~ ^/hindsight/(docs|openapi\.json|health|metrics|v1|mcp) {
proxy_pass http://hindsight_api;
proxy_set_header Host $http_host;
}
# Control Plane static files
location ~ ^/hindsight/_next/ {
proxy_pass http://hindsight_cp;
proxy_set_header Host $http_host;
}
# Control Plane UI
location /hindsight {
proxy_pass http://hindsight_cp;
proxy_set_header Host $http_host;
}
location = / { return 301 /hindsight; }
}
}
```
### Why Build is Required
Next.js requires `basePath` at **build time**. The published image was built without a custom base path, so you must rebuild from source with the `NEXT_PUBLIC_BASE_PATH` build arg to deploy the Control Plane under a subpath.
The API works without rebuild because `HINDSIGHT_API_BASE_PATH` is a runtime environment variable.

# Hindsight API deployment with Nginx reverse proxy (API-only)
#
# This example deploys Hindsight API under the path /hindsight with:
# - Hindsight standalone image (API + Control Plane + embedded pg0)
# - Nginx reverse proxy (API only)
#
# Quick Start:
# docker-compose -f docker/docker-compose/nginx/docker-compose.yml up
#
# Access:
# API (via nginx): http://localhost:8080/hindsight/docs
# Control Plane (direct): http://localhost:9999
#
# For full stack deployment (API + Control Plane both under /hindsight):
# See README.md in this directory for instructions on building with basePath.
#
# Note: This configuration uses the published image (no build required).
# Control Plane is served directly because Next.js basePath requires
# build-time configuration. See README.md for the full stack option.

# Hindsight with Timescale Extensions
This Docker Compose setup provides a complete Hindsight deployment with **Timescale extensions**:
- **pgvectorscale** - DiskANN algorithm for disk-based scalable vector search
- **pg_textsearch** - High-performance BM25 text search
Both extensions are from [Timescale](https://github.com/timescale) and provide production-grade performance.
## Prerequisites
- Docker and Docker Compose installed
- OpenAI API key (or another LLM provider)
## Quick Start
```bash
# Set environment variables
export HINDSIGHT_DB_PASSWORD="your-secure-password"
export OPENAI_API_KEY="your-openai-api-key"
# Build and start
docker compose -f docker/docker-compose/timescale/docker-compose.yaml up -d --build
# Check logs
docker compose -f docker/docker-compose/timescale/docker-compose.yaml logs -f
```
**Access:**
- API: http://localhost:8888
- Control Plane: http://localhost:9999
## Stop and Clean Up
```bash
# Stop services
docker compose -f docker/docker-compose/timescale/docker-compose.yaml down
# Remove volumes (deletes all data)
docker compose -f docker/docker-compose/timescale/docker-compose.yaml down -v
```
## Configuration
### Environment Variables
| Variable | Description | Default |
|----------|-------------|---------|
| `HINDSIGHT_DB_PASSWORD` | PostgreSQL password | `hindsight_password` |
| `HINDSIGHT_DB_USER` | PostgreSQL username | `hindsight_user` |
| `HINDSIGHT_DB_NAME` | Database name | `hindsight_db` |
| `HINDSIGHT_VERSION` | Hindsight Docker image version | `latest` |
| `OPENAI_API_KEY` | OpenAI API key | (required) |
| `HINDSIGHT_API_LLM_PROVIDER` | LLM provider | `openai` |
### Why Timescale Extensions?
**pgvectorscale (DiskANN):**
- 28x lower p95 latency vs dedicated vector databases
- 16x higher query throughput at 99% recall
- 60-75% cost reduction (disk is cheaper than RAM)
- Best for large datasets (10M+ vectors)
**pg_textsearch (BM25):**
- High-performance keyword retrieval
- Native BM25 ranking algorithm
- Optimized for full-text search
## Troubleshooting
### Extensions not installed
Check if extensions are available:
```bash
docker exec -it hindsight-db-timescale psql -U hindsight_user -d hindsight_db -c "\dx"
```
You should see:
- `vector` (pgvector)
- `vectorscale` (pgvectorscale/DiskANN)
- `pg_textsearch` (BM25 search)
### Build fails
If the Docker build fails during pgvectorscale compilation:
1. Ensure you have sufficient memory (recommended: 4GB+)
2. Check Docker build logs for Rust compilation errors
3. Try building with more resources: `docker compose build --no-cache --memory 4g`
### Port conflicts
If port 5438 is already in use, modify the `ports` section in docker-compose.yaml.

# hindsight-all
All-in-one package for Hindsight - Agent Memory That Works Like Human Memory
## Quick Start
```python
from hindsight import start_server, HindsightClient
# Start server with embedded PostgreSQL
server = start_server(
llm_provider="groq",
llm_api_key="your-api-key",
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?")
# Stop server when done
server.stop()
```
## Using Context Manager
```python
from hindsight import HindsightServer, HindsightClient
with HindsightServer(llm_provider="groq", llm_api_key="...") as server:
client = HindsightClient(base_url=server.url)
# ... use client ...
# Server automatically stops
```
## Installation
```bash
pip install hindsight-all
```

# 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

"""Add GIN index on source_memory_ids for observation lookup performance
Without this index, queries using the array overlap operator (&&) or array
containment (@>) on source_memory_ids require a full sequential scan over all
observation memory_units. At ~77k observations this was measured at 45ms per
query, becoming a bottleneck during consolidation recall (57-64s timeouts) and
user recall (18-27s average).
The GIN index reduces these queries to index scans: 45ms → 0.049ms (927x
speedup). Recall dropped from 18-27s to ~6s, and consolidation recall
stabilised from timeout to ~15s.

The temporal retrieval entry-point query filters memory_units by occurred_start,
occurred_end, and mentioned_at using OR conditions. Without dedicated indexes the
planner falls back to a sequential scan of all bank rows after applying the
(bank_id, fact_type) index, then re-checks each date field.
These three partial indexes give the planner bitmap-index scan options for the
three most common date predicates, dramatically reducing the row set before any
embedding computation is required.
All indexes are created CONCURRENTLY so the migration does not block writes on
memory_units during production deployments. CONCURRENTLY requires running outside
a transaction block; see migrations.py for how this is handled safely.

"""Add covering and composite indexes to speed up link expansion graph retrieval.
Two indexes target the two bottlenecks identified by EXPLAIN ANALYZE on a 17M-row
memory_links table:
1. idx_memory_links_to_type_weight (to_unit_id, link_type, weight DESC)
The semantic incoming direction — finding facts that consider seeds as their
nearest neighbour — currently hits an expensive BitmapAnd of two separate
bitmap scans (to_unit_id bitmap ∩ link_type bitmap). A composite index
on (to_unit_id, link_type) turns this into a single index scan and reduces
latency from ~36 ms to < 5 ms per query.
2. idx_memory_links_entity_covering (from_unit_id) INCLUDE (to_unit_id, entity_id)
WHERE link_type = 'entity'
The entity co-occurrence expansion uses COUNT(DISTINCT ml.entity_id) and
joins on ml.to_unit_id. Without a covering index the planner must read
~2 500 heap pages to fetch entity_id and to_unit_id after the bitmap index
scan, adding ~230 ms of random I/O. INCLUDE adds those two columns to the
index leaf pages so the entire query can be served from the index (index-only
scan), eliminating the heap reads entirely.
Partial index (WHERE link_type = 'entity') keeps index size ~40 % smaller.
Both indexes are created with CONCURRENTLY so the migration does not block
concurrent reads or writes on memory_links. CONCURRENTLY requires running
outside a transaction block, so the migration emits an explicit COMMIT before
each statement and uses IF NOT EXISTS for idempotency.

GIN indexes use a "fastupdate" pending list by default: small writes are

"""Add internal_id to banks and per-(bank, fact_type) partial HNSW indexes
Revision ID: d5e6f7a8b9c0
Revises: a3b4c5d6e7f8
Create Date: 2026-03-11
This migration:
1. Adds internal_id UUID column to banks (stable identifier for index naming)
2. Drops the global HNSW index (competes with per-bank partial indexes)
3. Creates per-(bank_id, fact_type) partial HNSW indexes for all existing banks
(new banks get indexes created at bank-creation time via bank_utils.create_bank_hnsw_indexes)
Why per-(bank, fact_type) indexes:
- fact_type-only partial indexes are never chosen by the planner when bank_id is in the WHERE
clause, because the idx_memory_units_bank_id B-tree index always wins at planning time.
- Per-(bank, fact_type) partial indexes have both predicates matching → planner selects them.
- The global HNSW index competes for larger partitions (world, observation) and must be dropped.
For large deployments, create indexes CONCURRENTLY before running this migration:
SELECT internal_id, bank_id FROM banks;
-- for each bank and each fact_type in (world, experience, observation):
CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_mu_emb_{ft}_{uid16}
ON memory_units USING hnsw (embedding vector_cosine_ops)
WHERE fact_type = '{ft}' AND bank_id = '{bank_id}';
DROP INDEX CONCURRENTLY IF EXISTS idx_memory_units_embedding;

1. If HINDSIGHT_API_MCP_AUTH_TOKEN is set (legacy), validates against that token
2. Otherwise, uses TenantExtension.authenticate_mcp() from the MemoryEngine
- DefaultTenantExtension: no auth required (local dev)
- ApiKeyTenantExtension: validates against env var

1. Multi-bank mode (for /mcp/ root endpoint):
- Exposes all tools: retain, recall, reflect, list_banks, create_bank
- All tools include optional bank_id parameter for cross-bank operations
- Bank ID from: X-Bank-Id header or HINDSIGHT_MCP_BANK_ID env var
2. Single-bank mode (for /mcp/{bank_id}/ endpoints):
- Exposes bank-scoped tools only: retain, recall, reflect
- No bank_id parameter (comes from URL)
- No bank management tools (list_banks, create_bank)
- Recommended for agent isolation
Bank ID resolution priority:
1. URL path (e.g., /mcp/{bank_id}/) → single-bank mode

- Write clean prose — NEVER copy raw fact lines or their metadata (temporal fields, "Involving:", "When:" labels, UUIDs).
- Parenthesized metadata like (occurred_start=...) and pipe-separated labels like "| Involving: ..." are fact formatting — strip them entirely from observation text.

- "observation_id": copy the EXACT "id" UUID string from EXISTING OBSERVATIONS.
- One create/update may reference multiple facts when they jointly support the observation.

Link Expansion graph retrieval.
Expands from semantic/temporal seeds through three parallel, first-class signals
stored in memory_links:
1. Entity links — precomputed co-occurrence graph (created at retain time, bounded to
MAX_LINKS_PER_ENTITY per entity). Score = number of distinct shared
entities between the seed set and each candidate.
2. Semantic links — precomputed kNN graph (each new fact linked to its top-5 most
similar existing facts at insert time, similarity >= 0.7). Checked
in both directions since the graph is not symmetric. Score = weight.
3. Causal links — explicit causal chains (causes/caused_by/enables/prevents).
Score = weight + 1.0 (boosted as highest-quality signal).
All three signals are bounded at retain time, so no LATERAL fan-out caps are needed
at query time. Each expansion is a simple aggregation over a small result set.
For non-observation fact types the three expansions are issued as a single CTE query
(one roundtrip, one connection) with a `source` discriminator column so the Python
merge step can apply per-signal score transformations.

Combined semantic + BM25 retrieval for multiple fact types in a single query.
Uses UNION ALL of per-fact_type subqueries so that each arm has its own
ORDER BY ... LIMIT, enabling the partial HNSW indexes per fact_type instead
of forcing a full sequential scan (which the previous window-function approach
caused by using PARTITION BY inside ROW_NUMBER()).
Requires partial HNSW indexes per fact_type (idx_mu_emb_world,
idx_mu_emb_observation, idx_mu_emb_experience), created automatically by
Alembic migration a3b4c5d6e7f8_add_partial_hnsw_indexes.py.
HNSW is approximate — semantic arms over-fetch by 5x (min 100) and trim to
limit in Python to compensate. ef_search=200 is set globally on pool
connections at init time (see memory_engine.py) to improve recall on sparse
graphs.
fact_type values are inlined as literals (safe: they come from a controlled
internal enum, never from user input).
