Glossary

A

Agent Loop The core execution cycle in clawft: receive message, build context, run pipeline stages, call tools, return response. See Agent Loop.

Analyzer / AnalyzerRegistry Pluggable trait-based assessment analyzers. The AnalyzerRegistry holds registered analyzers (complexity, dependency, security, topology, data source) and runs them during weft assess. Custom analyzers implement the Analyzer trait.

AssessmentService Kernel-native SystemService that performs codebase analysis. Uses tree-sitter for symbol extraction, pluggable analyzers for findings, and logs all operations to ExoChain. See Assessment Workflow.

AppContext The top-level runtime container that holds the message bus, session manager, memory store, tool registry, and LLM adapter. Wrapped by the kernel's Kernel<P> struct.

B

Boot Sequence The ordered startup process: K0 kernel init, K1 process table, K2 IPC, ExoChain genesis, K3 WASM sandbox, then optional ECC and mesh layers. See Boot Sequence.

C

CBOR Concise Binary Object Representation. Used as the payload encoding inside RVF segments for compact binary serialization.

clawft The agent runtime layer of WeftOS. Provides the LLM pipeline, tool system, skills, channels (Slack, Teams, CLI, web), and the browser WASM sandbox.

clawft-rpc Shared RPC crate providing DaemonClient for both weft and weaver CLIs. Enables daemon-first operation with graceful local fallback. Uses line-delimited JSON over Unix domain socket.

E

ECC (Ephemeral Causal Cognition) The cognitive substrate layer. Maintains a causal DAG (directed acyclic graph), HNSW vector memory, impulse queue for ephemeral signals, and a cognitive tick loop that runs continuous reasoning. See ECC.

ExoChain A tamper-evident append-only hash chain (SHAKE-256) that records every significant kernel event. Provides cryptographic provenance for agent actions. See ExoChain.

G

Gate The governance enforcement point. Every agent action passes through a gate that checks capabilities, constitutional rules, and resource limits before allowing execution.

GGUF A quantized model format used for local inference. WeftOS plans to support 0.5B-7B parameter GGUF models via the ruvllm crate for on-device agent reasoning.

H

HNSW Hierarchical Navigable Small World graph. The vector search index used by ECC for nearest-neighbor retrieval over agent memory embeddings.

I

IPC (Inter-Process Communication) The K2 messaging layer. Agents communicate via typed message envelopes with A2A routing, pub/sub, and cron scheduling. See IPC.

K

K-Phases The kernel build phases: K0 (boot), K1 (processes), K2 (IPC), K3 (WASM sandbox), K3c (ECC cognitive), K4 (containers), K5 (apps), K6 (mesh). See Kernel Modules.

Kernel The central Kernel<P: Platform> struct that manages the agent fleet. Wraps AppContext with process tracking, service lifecycle, IPC, health monitoring, and a boot state machine.

M

Mesh The K6 peer-to-peer networking layer for cross-node agent coordination. Supports encrypted transport, discovery, and state replication without central servers.

P

PID (Process ID) Every agent gets a unique PID from the kernel's process table, enabling supervision, resource limits, and lifecycle management.

Pipeline The multi-stage message processing chain in clawft: context building, tool selection, LLM inference, response formatting. Configurable with custom stages.

Platform The trait abstraction (Platform) that lets WeftOS run on native (Linux, macOS, Windows), Docker, WASI, and browser WASM with the same kernel code.

R

RVF (Rust Vector Format) A binary segment format for storing embeddings, metadata, and knowledge bases. Uses 64-byte aligned segments with CBOR payloads and optional WITNESS chains for tamper evidence.

ruvector The upstream ecosystem of Rust crates providing vector search, neural routing, consensus, and distributed coordination. WeftOS integrates ruvector-cluster, ruvector-core, and related crates.

S

SONA (Self-Optimizing Neural Architecture) A learning system that records agent decision trajectories and uses them to improve routing and model selection over time.

W

WASI (WebAssembly System Interface) The WASM runtime target for server-side deployments. WeftOS builds for wasm32-wasip2 with HTTP, filesystem, and environment access.

WASM (WebAssembly) The browser build target (wasm32-unknown-unknown). Enables running the full clawft agent runtime in a web browser via wasm-bindgen.

Weaver The ECC cognitive modeler. Runs the HYPOTHESIZE-OBSERVE-EVALUATE-ADJUST loop on causal models within the kernel.

WeftOS The complete AI agent operating system. Three layers: clawft (agent runtime), kernel (OS abstractions), and ECC (cognitive substrate).

WITNESS Chain A hash chain appended to RVF segment files that proves the integrity of embedded knowledge. Each operation is cryptographically linked to the previous, creating tamper-evident provenance.
