# infrastructure/inference/

## Purpose

Inference adapter layer. The root module provides `DefaultProviderRegistry` (registers `InferenceProvider` instances) and `FirstAvailableRoutingStrategy`. Submodules cover shared HTTP client infrastructure (`commons/`) and the llama.cpp server adapter (`llama_cpp/`).

## Ownership

Adapter for LLM inference backends. Implements `core:inference` interfaces. No dependency on other `infrastructure:*` modules.

## Local Contracts

- `DefaultProviderRegistry` implements `ProviderRegistry` from `core:inference`.
- `FirstAvailableRoutingStrategy` is the default routing policy; extend only in `core:inference`, not here.
- All LLM responses are proposals — they must be validated by the core before affecting state (invariant #7). Adapters return raw responses; they do not validate.
- Network calls to the llama.cpp server are environment observations; results must be recorded as events by callers if replay must reproduce them (invariant #9).
- Model lifecycle (spawn/own the llama-server process) lives in `llama_cpp/`; the autonomous scheduler is intentionally unbuilt (see root CLAUDE.md).

## Work Guidance

Standard adapter rules apply (see parent `AGENTS.md`). HTTP client code uses Ktor CIO; blocking I/O in `withContext(Dispatchers.IO)`.

## Verification

```
./gradlew :infrastructure:inference:test --rerun-tasks
./gradlew :infrastructure:inference:commons:test --rerun-tasks
./gradlew :infrastructure:inference:llama_cpp:test --rerun-tasks
```
