## .slm

TinyRustLM model artifact format. It carries the compact model payload, tensor metadata, tokenizer metadata, quantization mode, dimensions, and checksums needed by the runtime.

## q8_0

An 8-bit symmetric block quantization path that stores 32 weights with a shared scale. It is the practical balance path for many tiny models.

## q4_0

A 4-bit block quantization path that packs two weights per byte. It reduces memory but increases unpacking work in WASM.

## ADP1 / ASP1 / ALR1

Adapter package families: raw f32 task delta, sparse f32 task delta, and low-rank task delta. They are sidecars, not replacement models.

## Selector registry

A local routing file that declares which model artifacts, manifests, receipts, module plans, and adapter families are eligible for browser selection.

## Runtime-smoke

Evidence that an artifact can load and execute in the runtime under a scoped test. It does not automatically mean broad assistant quality.
