sim_lib_agent/
lib.rs

1//! Agent runtime surfaces for SIM: agents, tools, memory, patterns, fixtures,
2//! fairness facets, and model-fabric contract re-exports.
3//!
4//! Model placement is resolved through the `model/at` catalog. In-process
5//! runners and registry `site` exports share that catalog: a loaded native or
6//! wasm library can register an opaque site value under a placement symbol, and
7//! this crate adapts that value into an `EvalSite` without adding site behavior
8//! to the kernel. `model/cached` wraps placements in a content-addressed
9//! cassette, so successful inference replies are replayable by normalized
10//! request content, model identity, parameters, result shape, and capabilities.
