### Description (declared)

# Temporal Knowledge Substrate

An MCP server that lets LLM agents accumulate organizational knowledge across sessions, scoped by domain, backed by Neo4j. Tools enforce structural invariants so the graph can't corrupt itself — no raw Cypher writes.

**Two-layer architecture:**
- **Process layer** — Domains own Sessions. Sessions chain forward in time via `NEXT_SESSION`. The arrow of time is enforced by the tool, not by instructions.
- **Knowledge layer** (append-only) — 10 ontological types + 5 sub-labels via Neo4j multi-labeling, connected by 11 relationship types. Knowledge evolves via `EVOLVED_FROM` chains — every prior moment is preserved, never overwritten.

**The principle:** the tool may make claims about the graph but may not make claims about consciousness. Collisions error rather than silently merge. Description changes always create a new chain node — `update_knowledge` and `retype_knowledge` do not exist by design. See `HOWTO.xml` for the operator-facing teaching, and `docs/design/` for the design archive.

## Prerequisites

- Python 3.10+
- [uv](https://docs.astral.sh/uv/) package manager
- Neo4j 5.x instance (local or remote)

## Quick Start

```bash
# Install
uv sync

# Run (stdio transport, default for MCP clients)
mcp-temporal-knowledge --db-url bolt://localhost:7687
```

## Configuration

All options can be set via CLI flags or environment variables. CLI takes precedence.

| CLI Flag | Env Var | Default | Description |
|---|---|---|---|
| `--db-url` | `NEO4J_URI` or `NEO4J_URL` | `bolt://localhost:7687` | Neo4j connection URL |
| `--username` | `NEO4J_USERNAME` | `neo4j` | Neo4j username |
| `--password` | `NEO4J_PASSWORD` | `password` | Neo4j password |
| `--database` | `NEO4J_DATABASE` | `neo4j` | Neo4j database name |
| `--transport` | `NEO4J_TRANSPORT` | `stdio` | Transport: `stdio`, `sse`, or `streamable-http` |
| `--namespace` | `NEO4J_NAMESPACE` | *(none)* | Tool name prefix (e.g. `myapp` -> `myapp-begin_session`) |
| `--server-host` | `NEO…
