# infrastructure/router/

## Purpose

Router infrastructure adapters. Currently contains one submodule: `turbovec/`, which provides `TurboVecL3MemoryStore` — a durable L3 (cross-session) memory store backed by a Python TurboVec sidecar process communicating over stdio.

## Ownership

Adapter for `core:router` L3 memory interfaces. No source in the root `router/` module itself; all code lives in `turbovec/`.

## Local Contracts

- `TurboVecL3MemoryStore` implements `L3MemoryStore` from `core:router`.
- The TurboVec sidecar is a Python process; `SidecarProtocol` defines the stdio JSON message protocol.
- The bundled `turbovec_sidecar.py` script is extracted from the classpath to `~/.cache/correx/` at startup by `InfrastructureModule`.
- Similarity search results are environment observations (ANN index query); callers must record retrieved memories as events if replay correctness requires them (invariant #9).
- `TurboVecSidecarConfig` is the only configuration surface.

## Work Guidance

Standard adapter rules apply (see parent `AGENTS.md`). Sidecar communication is async; never block the calling coroutine waiting for the process without `withContext(Dispatchers.IO)`.

## Verification

```
./gradlew :infrastructure:router:turbovec:test --rerun-tasks
```
