The ketraterm-core module is a high-performance, headless terminal grid engine. It implements the headless screen-state engine, coordinates all spatial grid mutations, manages cursor physics, scrollback margins, and controls alternate/primary screen switches.

The ketraterm-host module serves as the production bridge and adapter layer between the byte-stream parser (ketraterm-parser) and the headless state machine/grid engine (ketraterm-core).

The ketraterm-input module is the platform-agnostic, host-bound input encoding engine for KetraTerm Terminal. It converts UI-level, platform-neutral events—such as keyboard presses, text paste, window focus transitions, and mouse pointer actions—into standardized ANSI/DEC/xterm byte sequences written to the terminal host's input stream.

The ketraterm-parser module is a high-performance, strictly bounded, and allocation-conscious parser that transforms raw terminal host byte streams (from a PTY, SSH, or network socket) into semantic terminal command invocations.

The ketraterm-protocol module represents the zero-dependency, immutable core vocabulary of the KetraTerm Terminal pipeline. It defines the fundamental, standard-aligned constants, enumerations, and interfaces shared by all terminal components.

The ketraterm-pty module owns the lifecycle management, process stream pumping, and terminal size synchronizations of local, host-backed pseudo-terminal (PTY) processes.

The ketraterm-render-api module defines the strictly bounded, dependency-free public render contract and vocabulary shared across the terminal pipeline. It acts as the immutable, allocation-conscious bridge between stateful terminal state providers, frame caches, and UI rendering modules.

The ketraterm-render-cache module provides a high-performance, renderer-side double and triple-buffering publication system for KetraTerm Terminal. It consumes short-lived render frames exposed by :ketraterm-render-api and stores flat, primitive-packed, allocation-free snapshotted layouts.

The ketraterm-session module is the central orchestration hub and runtime synchronization engine of the KetraTerm Terminal pipeline. It coordinates the data-flow between the asynchronous transport layer, the byte-stream parser, the headless terminal grid, and platform-agnostic keyboard/mouse input encoders.

The ketraterm-testkit module is the dedicated test double and mock harness module for KetraTerm Terminal. It provides in-memory connectors and lifecycle simulation tools for testing terminal runtimes, transport layers, and host-bound input/output loops without spinning up physical shells, PTYs, or socket connections.

The ketraterm-transport-api module defines the transport-neutral, highly performant connection contracts between terminal runtimes and host byte-streams.

A reusable, premium-tier Swing terminal component built in Kotlin/JVM 21.

The ketraterm-workspace module provides a host-neutral session and tab manager for KetraTerm Terminal. It coordinates multiple active terminal sessions (tabs) under a unified workspace lifecycle, maps configurations onto file-based profiles, and implements standard TOML-backed settings persistence.
