## Overview

#### Purpose and entry point
This is a compact Rust application centered on algorithmic processing and movement-related logic. The executable entry point is `src/main.rs`, with domain code grouped under the `stuff` module tree.

#### Application composition
`src/main.rs` likely initializes settings, constructs domain data, and invokes the primary algorithms. The module root `src/stuff/mod.rs` defines the internal package boundary and exposes the submodules used by the binary.

Key paths:
- `src/main.rs`
- `src/stuff/mod.rs`

#### Domain model and configuration
`src/stuff/datatypes.rs` contains the core data structures passed between algorithm stages. `src/stuff/settings.rs` represents runtime or algorithm configuration, separating tunable parameters from processing code.

Primary flow: startup reads or constructs settings → creates/loads domain data → hands both to algorithms.

Key paths:
- `src/stuff/datatypes.rs`
- `src/stuff/settings.rs`

#### Core algorithm layer
`src/stuff/algorithms.rs` is the likely general-purpose computation/orchestration layer. It should own high-level algorithm selection, evaluation, or transformation over the domain types rather than embedding those concerns in `main`.

Key path:
- `src/stuff/algorithms.rs`

#### Movement algorithm boundary
`src/stuff/move_algos.rs` isolates movement, traversal, routing, or state-transition behavior from the broader algorithm layer. This is an important architectural boundary: movement-specific decisions can evolve independently while operating on shared types from `datatypes.rs`.

Key paths:
- `src/stuff/move_algos.rs`
- `src/stuff/datatypes.rs`
- `src/stuff/algorithms.rs`

#### Shared operational utilities
`src/stuff/tools.rs` holds reusable support operations used by algorithm modules. It should remain a dependency leaf where possible: higher-level modules may call it, but it should avoid owning application flow or movement policy.

Key paths:
- `src/stuff/tools.rs`
- `src/stuff/algorithms.rs`
- `src/stuff/move_algos.rs`

#### Runtime and deployment
The runtime is Rust, defined by `Cargo.toml` and compiled into the binary rooted at `src/main.rs`. Container deployment is supported through `Dockerfile`; stage and production deployment are represented by Windows batch scripts.

Key paths:
- `Cargo.toml`
- `Dockerfile`
- `deploy_stage.bat`
- `deploy_prod.bat`

No external services, persistence layer, or web/server entry point are identifiable from the supplied tree.
